Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Why i’m bullish on Zilliqa (long read)

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analysed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralised and scalable in my opinion.
 
Below I post my analysis why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors.

Mainnet is live since end of January 2019 with daily transaction rate growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralised and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. Maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realised early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralised, secure and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in amount of nodes. More nodes = higher transaction throughput and increased decentralisation. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue disecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as:
“A peer-to-peer, append-only datastore that uses consensus to synchronise cryptographically-secure data”.
 
Next he states that: >“blockchains are fundamentally systems for managing valid state transitions”.* For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralised and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimisation on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (>66%) double spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT etc. Another thing we haven’t looked at yet is the amount of decentralisation.
 
Decentralisation
 
Currently there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralised nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching their transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public.They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers.The 5% block rewards with an annual yield of 10.03% translates to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS & shard nodes and seed nodes becoming more decentralised too, Zilliqa qualifies for the label of decentralised in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. Faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time stamped so you’ll start right away with a platform introduction, R&D roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalised: programming languages can be divided into being ‘object oriented’ or ‘functional’. Here is an ELI5 given by software development academy: > “all programmes have two basic components, data – what the programme knows – and behaviour – what the programme can do with that data. So object-oriented programming states that combining data and related behaviours in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behaviour are different things and should be separated to ensure their clarity.”
 
Scilla is on the functional side and shares similarities with OCaml: > OCaml is a general purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognised by academics and won a so called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities safety is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa for Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue:
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships  
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organisations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggest that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already taking advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, AirBnB, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are build on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”*
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They dont just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities) also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiatives (correct me if I’m wrong though). This suggest in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures & Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

AMA Recap of CEO and Co-founder of Chromia, Henrik Hjelte in the @binancenigeria Telegram group on 03/05/2020.

Moh (Binance Angel)🇳🇬,
Please join me to welcome, “CHROMIA CEO & Co-founder, Henrik Hjelte” and “ CMO, Serge lubkin”
Oh, before we proceed, kindly introduce yourselves and tell us a bit about your roles at Chromia u/sergelubkin & u/henrik_hjelte.
Henrik Hjelte,
Ok, I’m Henrik, I’m CEO of ChromaWay that crated the Chromia project. My background is a bit mixed: developer for 30+ years (since 80: s), but I studied other things at university (economics, politics, social sciences philosophy). Life is more than computer you know… I worked with FInance/IT then started a web startup and got to know Alex Mizrahi who worked as a developer….
Web startup didn’t fly, but Alex showed me bitcoin. When I finally read the whitepaper I was blown away, and joined Alex colored-coins project, the first open source protocol to issue tokens. in 2013.
So, we started with open-source tokens (that kickstarted the blockchain industry. Then started company together 2014.
That is a long intro, I’ll shut up now… Thanks….
Serge,
I’m Serge, I’m assisting Henrik today and I work with Chromia marketing team as well as on some business development projects
Moh (Binance Angel)🇳🇬, , Question No 1 :
Kindly describe the CHROMIA project and what it aims to achieve?
Henrik Hjelte,
Chromia is a new public blockchain based on the idea of integrating traditional databases, Relational databases with blockchain security. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and normal languages but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains. There is a blog post about it, I’ll share later. On lines of code.
The aim of Chromia is to combine relational databases, which exist in every kind of organization, together using blockchains. We want to provide a platform for our users to develop totally decentralized apps securely. Our goal is for Chromia to be seen as the number one infrastructure for decentralized applications.
https://blog.chromia.com/reasons-for-rell-compactness/
Moh (Binance Angel)🇳🇬,Question No 2:
What inspired the CHROMIA Core team to pick interest in CHROMIA project? what breakthrough have you achieved so far? what are the present challenges you’re facing and how are you planning to overcome them?
Henrik Hjelte,
We started with public blockchains, tokens in 2012, the world’s first stable coin with a bank 2015 (LHV). When coding that solution, peer to peer payments of Euro-tokens, we discovered we need performance reasons to store all data in a database. We needed to quickly know the “balance” of a user, and can’t loop through a blockchain. And slowly the idea grew that we can make the database INTO a blockchain, integrate completely with the transaction mechanism of a database. So, we did it as a private blockchain first (Postchain), used it for some projects, then came up with the idea to make a Public Blockchain based on it.
The motivation is that we felt we needed a better programming model for blockchains. Our CTO Alex has always been thinking of optimal solutions for blockchain technology and has lots of experiences thinking about it. Also: make real-world useful things. For example, we support free-to-play models since users do not need to own “our” token to USE apps, the application itself (often the developer) pays for hosting. And of course, great performance. Also: more knowledge of who runs nodes and risk level. So, it is more suitable for enterprises.
In Chromia the application (at the start the developer) decides Who should be allowed to run its own blockchain (every dapp has its own blockchain). You can also say on a higher level that we want to provide technology to create “Public applications”, a tool
that enables us to create a fairer world.
https://blog.chromia.com/towards-publicly-hosted-applications/
Moh (Binance Angel)🇳🇬, Question No 3 :
Why did you create your own blockchain instead of leveraging on existing and proven base layer protocol?
Henrik Hjelte,
None of the existing protocols are suitable to support large-scale, mainstream applications. We designed Chromia to give our users exactly what they want; fast support, useful features, with an affordable service cost. Other platforms do not have the ability to host data applications in a decentralized and secure way, as Chromia can. Chromia also has its own bespoke programming language that sets it apart from SQL-based platforms. It’s so easy to use, even non-developers can understand it!
The other big difference with Chromia concerns payments. Chromia gives its users freedom from having to pay for each transaction. With Chromia, you have the flexibility to decide how to set fees for your dapp
And when it comes to “proven base layer protocols”: they are just a few years at max. Chromia is built on top of Postgresql, that has been used in enterprises for decades, a really proven technology. And the Java virtual machine on top of that. This is proven tech, at core.
Moh (Binance Angel)🇳🇬, Question No 4 :
What is Postchain?
Henrik Hjelte,
Postchain is an open-source product of ChromaWay for enterprise clients and it’s the core technology on which Chromia is built.
Postchain is a replicated blockchain and database that offers highly resilient distributed database management with distributed control.
Postchain is the only product on the market that combines the immutable consensus of a blockchain and the properties of a real database management system (You know, the tech that built SAP, Facebook, Banks…) …
Postchain allows you to share information between companies and/or individuals in a secure and transparent way.
That is the low-level base of Chromia you can say
Moh (Binance Angel)🇳🇬,
Can you please name some of your clients that are using this service already?
Serge,
You mean products built on Postchain? Also, Stockholm Green Digital Finance, Green Assets Wallet that’s now functioning on Chromia Bootstrap Mainnet.
Big financial institutions
It’s only a beginning of course, but very promising one. https://greenassetswallet.org/news/2019/12/12/launch-of-the-green-assets-wallet
Henrik Hjelte,
We got a lot of attention with the Swedish Land registry; we did a joint project between them and banks and a telco etc on postchain as base.
Then, right now we do a large project with the Inter-American Development bank also about land-registration (processes) in South America.
We had a client, Stockholm Green Digital Finance, that did a system for green bonds (tracking environmental impact. Yes, as Sege says, it was later moved to Chromia…
Which is cool. Also, another external development company did that phase of the project, proving that other can build on our tech,4irelabs from Ukraine is their name. Some companies using the GAW: Blackrock. SEB Bank etc…
Also, we have done more projects, in Australia, asia etc. Oh Daimler too (the Mercedes company) …
Moh (Binance Angel)🇳🇬,
Lots of enterprise clients you’ve got. No wonder I do see the meme “CHR=ETH KILLER”
Serge,
It’s a meme from our supporters. But we believe we can coexist:)
For some niche things eth is good :)
So, no killing :D
Henrik Hjelte,
We want to work with partners too for this, we can’t do all projects ourselves. Also, for Chromia projects, ChromaWay company can help do support maintenance etc. So, it is not competing, it adds value to the ecosystem.
Yeah ETH is good too, for some applications. We are friends with them from colored-coin times.
And colored-coins inspired ETH, and ETH inspires us.
Moh (Binance Angel)🇳🇬, Question No 5 :
Lastly, CHROMIA is already doing very well in terms of business. You just got listed on BINANCE JEX, you are on-boarding new clients and dishing out new features. But what’s next? Is there anything to be excited about?
Henrik Hjelte,
Plans for 2020 are to both release a series of dapps to showcase how fantastic Chromia is, as well as continue to develop the platform. And when it is secure and good enough, we will release the mainnet.
Dapps are now being made by us as well as others. We do a decentralized social network framework called Chromunity, now released to TestNet. It is really cool, users can vote over moderators, and in the future users might even govern the complete application, how it can be updated. This is a great showcase for Chromia and why we use the slogan Power to the Public.
https://testnet.chromunity.com/
Games coming are:
Mines of Dalarnia (by Workinman Interactive). An action game in a mine with blockchain rental of plots and stuff. Already on TestNet and you can take a peek on it at https://www.minesofdalarnia.com
more coming…
Krystopia 2, novas journey. A puzzle game done by Antler Interactive. Could only find trailer though: https://www.youtube.com/watch?v=-G95-Dw3kI4
However, we have even larger ambitions with blockchain gaming…
We are doing A secret demo-project that we do together with Antler to showcase the technical potential of Chromia platform.
Another exciting relase is an indie game Chain of Alliance, done by two external developers. It is a strategy game with full-logic on blockchain. Public release on TestNet on May 22!
More coming in 2020: Other dapps from other companies, one in impact-tech.
That is a serious app, Chromia also works outside gaming and social media for enterprises and startups
And I hope some of you will do something, we want to support dapps on the platform so reach out to us…
Moh (Binance Angel)🇳🇬,
When can we be expecting the mainnet? Any approximate time? I’m sure the community will really excited to have that info
Serge,
It’s now in Bootstap phase, so it’s technically already functioning. MVP will be very soon
Stay tuned;)
Twitter questions Vs answers
Ellkayy,
What’s the unique thing in Chromia that no other blockchain has, that makes you the better option?
Henrik Hjelte,
Unique: Chromia is the only blockchain that also has a real, proper database built-in. And blockchain is about managing data in a shared context. How to best managed data was solved in computer science already. So far, it is the relational algebra model that is used in 100% of all enterprises, and has an 85% market share. Chromia is the only blockchain that use that model and that power.
Ellkayy,
Why Chromia use RELL and not SQL or JavaScript? Can developers with other language knowledge use Chromia?
Serge,
Rell is the only language on the blockchain side. You can combine with anything on client-side, although now client only exists for JS/TS, C# and Java/Kotlin. Rell is a language for relational blockchain programming. It combines the following features:
1 Relational data modeling and queries similar to SQL. People familiar with SQL should feel at home once they learn the new syntax.
2 Normal programming constructs: variables, loops, functions, collections, etc.
3 Constructs which specifically target application backends and, in particular, blockchain-style programming including request routing, authorization, etc.
Rell aims to make programming as convenient and simple as possible. It minimizes boilerplate and repetition. At the same time, as a static type system it can detect and prevent many kinds of defects prior to run-time.
Roshan DV,
I have been monitoring your project for a while but some concerns about it: Your project will build your own core network, so you have more visibility than Ethereum and NEO. These are projects that were born before and which also have a very large community. And what can assure you that your project will guarantee the functionalities that you have defined?
Henrik Hjelte,
What came first? I want to remind that Vitalik was in the colored-coins project, led by our CTO and we had blockchain in production before ETH and NEO etc existed. We are the old dogs…
Large community: We are part of the same community. When developers are fustrated and want to try new tech, they go to us from other blockchains.
Also, we have a large potential: SQL (close to Rell and our tech) is the world top 3 language. Bigger than Java. Bigger than PHP. Only beaten bny HTML and javascript. Soliditiy is not on top 20 list. THere are millions of developers that know SQL. That is potential for community… (source is Stackoverflow annual programming survey).
Paul (Via Manage),
What are the utilities of Chromia and what purpose does the Chromia coin serve?
Serge,
Chromia meta-token called Chroma (CHR). It is used in Chromia to compensate block-producing nodes by fees. In Chromia, fees are paid by dapps, which can in their turn collect fees from users. Chromia provides mechanisms which balance the interests of developers and users. Dapp tokens can be automatically backed with Chroma, providing liquidity and value which is independent of investment into the dapp. Dapp investors can be compensated in Chroma through a profit-sharing contract. For developers, Chromia offers the opportunity to derive income from dapps. This incentivises the creation and maintenance of high quality dapps because better dapps generate more income and create more demand for tokens owned by the developer. The Chromia model is designed to support sustainable circular economies and foster a mutually beneficial relationship between developers, users, and investors.
Idemudia Isaac,
Thank you very much u/henrik_hjelte u/sergelubkin
You stated your plans for 2020 is to release series of dApps. What kind of large scale, mainstream decentralized application and $Chromia products do you think is suitable for the Nigerian environment?
Henrik Hjelte,
Actually, this is why we want to work with partners. We cannot know everything, For African market we have seen of course payments/remittances (but it has fallen out of trend). We would love to do real-estate /land-registration but we understand we need a strong local partner (more than a single person, a real company or organization driving).
●CC● | Elrond 🇵🇭,
What plans do you have to building a vibrant global community around Rell? And how would you go about encouraging/incentivising such ‘Rellists’ around the world to build dApps on Chromia? u/henrik_hjelte u/sergelubkin
Henrik Hjelte,
For developers (I am one too, or used to be) you normally need to prove a few things:
\ That the tech is productive (can I do apps faster?)*
\ That it is better (less bugs, more maintainable?)*
Then the community will come. We see that all the time. Look at web development. React.js came, and developers flooded to it. Not because of marketing on Superbowl, but because it was BETTER. Fewer bugs and easier to do complex webapps.
So, at core: people will come when we showcase the productivity gains, and that is what we need to focus on.
●CC● | Elrond 🇵🇭,
Why do you choose to build Chromia token on ERC20 instead of other blockchain such as BEP2, TRC20…or your own chain while ERC20 platform is very slow and have a case of fee? u/henrik_hjelte u/sergelubkin
Serge,
So far Ethereum has the best infrastructure, it’s the oldest and most reliable network for tokens. It also became the industry standard which exchanges utilize. We will transfer 80% of all erc20 tokens to our Chromia blockchain when it’s ready for that.
Koh,
In your whitepaper it says in the upcoming version of ChromiaWallet that it will be able to function as a Dapp browser for public use. Q) Will it be similar to the Dapp browser on Trust Wallet?
Serge,
It’s live already try it http://vault-testnet.chromia.com/
It’s the wallet and a dapp browser
CHROMIA is SOLID,
Your metamorphosis is a laudable one,surviving different FUD, how have you been able to survive this longest bear market and continue building and developing cos many projects have died out in this time period!
Henrik Hjelte,
You need to know we started a company before ETH existed. There was 0 money in blockchain when we started. I did it becuase it was fun, exciting tech and MAYBE someone would be interested in the thing we made “Tokens”…
We were never in the crazy bull-market, manly observed the crazies from the side. We fundraised for CHR in a dip (they called it bear market). ChromaWay the company also make money from enterprises.
Алекс,
What is SSO?
What makes it important for chromias ecosystem?
Why should we users be attracted to it?’
Serge,
Chromia SSO is perhaps the most important UX improvement that Chromia offers the decentralized world. It revolutionizes the way users interact with dapps. Any dapp requires users to sign transactions, that means they need a private key. Control of the private key is control of any and all dapps or assets associated with it. This means that private keys have an especially stringent set of security requirements in a blockchain context — they control real value, and there is no recourse if they are compromised or lost. https://blog.chromia.com/chromia-sso-the-whys-and-the-whats/
Olufemi Joel,
How do you see the Chromia project developing in 3 to 5 years, both on the commercial level and on the evolution of the company? What are the plans for expansion in different regions? Are you going to outsource the team/skills or keep it centralized and set up offices?
Henrik Hjelte,
I take part of the question. On outsource: we were a distributed team from day one, with co-founders from 3 countries (still living there). We are distributed now, Ukraine, Sweden, Vietnam, Croatia, China are “hubs” then we have individuals too. No big plan, just where we found great developers…
Park Lee, u/henrik_hjelte
You claim CHOROMIA have fast support, useful features with an affordable service cost. That fast and the fees are cheap but can you guarantee stability?
What’s the Algorithms which are used by CHROMIA for that fast? And Can you explain it?
Serge,
We use PBFT protocol with some features of DPOS, this plus sidechains parallelism offers almost unlimited speed and scalability. We also use the feature called anchoring to secure all transactions in batches on Bitcoin blockchain.
Mario Boy,
What are you guys trying to achieve as an end goal? The next Ethereum? Or the next enterprise version of Ethereum? Or something different?
Henrik Hjelte,
The end goal… good question. When we started in 2014 there were no other blockchain companies, so we wanted to do the best blockchain technology in order to enable a decentralized world with more fair applications. And that is what we still do. Technology/software that can enable people to make a fairer world
Erven James Sato,
“STAKING” is one of the STRATEGIES to ATTRACT USERS and ACHIEVE MASS ADOPTION
Does your GREAT PROJECT have plan about Staking?
Serge,
Yes, we announced our staking plans couple of months ago https://blog.chromia.com/on-providers-and-stakes/
We are working with our current partners to make it accessible for general public.
Chizoba,
I often see Chromia and ChromaWay being used interchangeably, what is the relationship between the two?
Henrik Hjelte,
ChromaWay the company started Chromia from code done as postchain. This is normal in open-source development, a company that leads development. But Chromia will be a decentalized network, so ChromaWay will not make direct money out of it more than if we have a role as a Provider (and get payed for hosting). ChromaWay can indirectly make money from optional support and maintenance etc. Also, this, perfectly normal in open-source world.
And it also benefits Chromia that there is a market for support.
A market open for competition.
No special treatment for “ChromaWay”
Enajite,
How to start coding on Chromia?
Henrik Hjelte,
Go to https://rell.chromia.com and follow the tutorial. Enjoy the free time you get compared to other blockchain languages…
●CC● | Elrond 🇵🇭,
Chromia process 500 TPS, these is slow compare to other Blockchains, where we can see now 60K TPS if more capacity require, how can that be? u/henrik_hjelte u/sergelubkin
Serge,
Yes, if you need faster speed you can use parallelism by having multiple blockchains for your dapp. Also, by optimization and better architecture sky is the limit.
Delphino.eth ⟠,
Can we consider Chromia an hybrid? For its mixing of Blockchain and a Database?
Henrik Hjelte,
Yes and no. I want to stress that Chromia is a FULL blockchain. It is not only “inspired”. It is a blockchain AND a database.
I tend to think about Hybrid more in the usecases that you might have as a customer. For example, a bank might want to have some data/transactions private (as a private blockchain) and have another half of the application with public data (on Chromia). So that is a hybrid solution, and Chromia ROCKS in that segment since it is the only blockchain that is complete relational database (what the normal world uses anyway for 85% of all applications)
Example area: “open banking”
Steve bush,
How will Chromia I have any empower Investors, Companies, Developers, Platform Users to
deliver impactful solutions and bring value to people all over the world?
Henrik Hjelte,
In order to make blockchain go big, we need to have users. Users need to be able to use apps with ease. Chromia have features like single-sign on (ease of use), but importantly do not require owning tokens to USE apps.
Also, it needs to be easy to make applications. For example, if you are a student in US and came up with an idea, you want to make an application for your school. Let’s call it “thefacebook”. You code something in PHP and MySQL. DID YOU SEE THAT. SQL. SQL.SQL. It is the same tech that Chromia has but no one else in the blockchain business. SQL rules the world if you look outside the crypto bubble. Google the Oracle head-office… 100% of all enterprises use it… Because it is easy and powerful.
And we even improve on SQL with Rell….
So, compare that with a hacky virtual machine that have a few years…. 😊
August,
“Mines of Dalarnia” is a game that has caught my attention a lot, due to its simplicity and quality. But in the time that I have used it I have not been able to differentiate between the Chromia blockchain of this game and that of the competition? What other games do you have next to develop? I would like to give ideas in those games like a Gamers!
Henrik Hjelte,
We thought about in corona time sports club might want to engage more with their fans digitally. And of course, E-Sports is getting a real momentum as the young generation grows up. Now a bit sad that all games are centralized. My daughter will be sad when (at some day?) they will close down roblox… it happens to all centralized apps eventually… that is what we fix. Power to the Public to control apps and their future. I’ll repost again Alex post. Sorry I like it a lot… https://blog.chromia.com/towards-publicly-hosted-applications/
Bisolar,
Good day Chromia team from a Chromia fan
Can you tell us Chromia’s geographical focus at the moment and the proces it follows for it BUSINESS DEVELOPMENT?
What factors do you consider before identifying NEW MARKETS to enter?
Serge,
Chromia will initially focus on community building in China, Korea, US and Europe. The focus of community growth will gradually expand to other markets as the project gains popularity.
Current community growth strategies of Chromia include:
Chromia blockchain incubator creation to welcome more projects to the Chromia blockchain
Host blockchain gaming conferences, workshops, and meetups to engage with potential users.
Provide online and face-to-face tutorials to engage with dapps developers.
Attract blockchain developers through direct and indirect approach via specialized platforms and communities.
Develop our relations with existing and previous corporate clients, and their partnership networks to participate in their blockchain ventures
Launch Node program to encourage system providers to run nodes on the Chromia blockchain.
Staking program for Chroma (CHR) tokens
Active community engagement via social channels.
Future community growth strategies of Chromia after Mainnet launch include:
Partner with more gaming studios, startups and enterprises
Build local communities with Ambassador Programs.
Partner with external incubator and accelerators to provide blockchain expertise and introduce projects to Chromia ecosystem
Continue organizing hackathons around the world to attract more developers.
Emmanuel,
I want to know the current structure of your roadmap? What is the future roadmap of CHROMIA? Is there any key milestone coming???
Henrik Hjelte,
It is easy to do a roadmap; anyone can make a pape plan. But I think they are used in the wrong way. Software is hard, blockchain is even harder because it NEEDS TO BE SECURE. No MVP releases. We cannot even have roadmap deadlines and skimp on quality. Where we are now though is: Rell language finished so much that developers can write apps and see its magic. We have external devs doing dapps. We have the first phase of mainnet. We have a series of releases coming up. We will release mainnet when it is secure enough, and gradual roll out. I think quite soon, development is going great at the moment, a bit quicker than we though.
Ellkayy,
Why doesn’t Chromia transactions use gas? How do you power transactions then?
Serge,
Main feature of gas in Ethereum is to pay for transactions for miners get rewards. In our scenario Providers get rewards from dapp owners. So dapp owner pays for storing their dapp. It’s like Amazon Web Service model. Then dapp owner can monetize it in its own way.
Ellkayy,
Many developers don’t know RELL, just Solidity and SQL. Is this a barrier or threat to Chromia? Why RELL is better?
Henrik Hjelte,
Very few developers know Solidity. Do a search on github. I referred previously to stackoverflow programming language survey results. https://insights.stackoverflow.com/survey/2019#technology
If you know SQL, you learn Rell in a day.
SQL is the top 3 language here. I’d say there are millions that can easily jump to Rell.
Soldity or other blockchains, not on top 20 list even.
Rell is a hipper, nicer version of SQL that is also a “normal” programming language.
Developers like to learn new things, new languages. Otherwise we would be stuck with PHP, the DOMINANT language. Well, is it still? Seems javascript and react.js and node etc is taking over…

Hi everyone. Pleased to be here! Thank you for taking your time to join me.
I’m the Chief Business Development Officer for TomoChain.
Educationally I graduated university with degrees in both Industrial Engineering and Economics from Georgia Tech, and later earned an MBA from the Wharton School of Business.
I grew up as a gaming addict and have a video game collection that is a bit unwieldy. Dozens of consoles and, at one point, over 13 classic arcade machines.
So, before crypto, I spent much of my profession in the gaming space. I was a Game Designer, Game Producer, and eventually Studio Head for a major games studio that was recently purchased by Rockstar Games. I have run my own game-related tech businesses as well.
I fell into crypto back in 2014, and over time it became a second passion of mine as I began to truly understand the value of decentralization. True ownership of data was not possible until Bitcoin came along and that is simply a powerful and game-changing message to a world structure built on an opposing foundation.
Brief Introduction

https://preview.redd.it/8p7jm15ul5t41.png?width=739&format=png&auto=webp&s=8b572bdee2c56ffa29a1d628dda7332fac0fac50
TomoChain is a Public Blockchain powered by Proof-of-Stake Voting. TomoChain launched into Mainnet 1 year ago in December 2018. It is secured by 150 Masternodes, of which I’m proud to be an operator myself. TomoChain is EVM Compatible and runs at a speedy 2000 TPS with a 2 Sec Blocktime. Gas fees are almost zero too.
Based out of Vietnam, TomoChain is Southeast Asia’s largest public blockchain. We are focusing on developing a full suite of DeFi products. We also have commercial and enterprise clients. TomoChain has a number of major crypto-partnerships including notables like Neo Blockchain, Chainlink and Crypto.com. Our Masternode network is run by some of the most recognizable players in the space as well, including Neo Global Capital, CoinGecko, HashQuark, KuCoin, and more large players are on the way.
TomoChain earned its place onto Binance.com with a fee-free listing last year by winning the BinanceDEX community vote in August 2019. Binance has written us up in a detailed Binance Research Report and awarded us the V-Label. We have also been in a number of their reports, including those related to Dapps and DeFi. We have been interviewed by Forbes.com official and had an in-person interview at NASDAQ, in the heart of Times Square, about TomoChain and our upcoming TomoX Protocol.
In China, specifically, we have been integrated into and have solid relationships with various blockchain players including HashQuark, HashKey, CoboWallet, Conflux, and many others. We launched an Ecosystem Development partnership with Neo Blockchain last December and co-hosted a meetup + workshop with them as well.

GEARED FOR REAL WORLD USE
Now, let’s talk about how TomoChain has been built for real-world use.
We’re looking at Payments & DeFi as low hanging fruit when it comes to user adoption and TomoChain is developing a suite of tools to support this. The biggest challenge for having users benefit from Blockchain on a day-to-day basis is how much friction is involved to acquire, store and use it. Even stable coins are dual currency systems. The Stablecoin and then the Native Token to pay gas fees. Blockchain is simply not user-friendly.
Our view is that the true solution for Blockchain adoption by the world is end-users shouldn’t need to know they are using blockchain technology at all. It should be a hidden technology layer, similar to payment processor settlements or even the internet distribution centers/routers that power this very AMA we’re all participating in right now. Do we need to know the underlying technology infrastructure to use them? Nope.
We are developing a system to hide this friction, so the TomoChain blockchain can be integrated into real-world applications that you use every day on mobile or web.
There are 3 protocols that we are building to enable this future: (1) TomoZ: Zero Friction (2) TomoX: The DEX Protocol (3) TomoP: The Privacy Suite.

https://preview.redd.it/irwduto4m5t41.png?width=741&format=png&auto=webp&s=56e21c8e56b86af197344d7a043d073456c53181
TomoZ: Zero Friction - Our TomoZ protocol is a core starting point to the solution for mass market use of blockchain technology. TomoZ: Zero Friction allows for token issuance and use by having gas fees paid by the token itself. That means you don’t need TOMO to send transactions. You don’t even need to know you’re using the TomoChain blockchain.
So you could buy a cup of coffee at a café using loyalty points that are TomoZ tokens. The customers redeem for their coffee or earn it, but they don’t even have to know it’s a blockchain token which they actually own.
This approach is structured to enable the next million-plus users to utilize blockchain as a technology layer. After all, the real value of any Blockchain is in its utilization of high-quality transactions.
Now, TomoZ transactions aren’t FREE. It actually does use TOMO, but that’s hidden from the end-user. The way it works is that the token issuer deposits a small amount of TOMO into a pool. Every time the token is sent, TOMO is taken from this pool to pay the Masternodes.
The key is that the end-user doesn’t need to get involved with internal workings, which is why we call it the Zero Friction protocol
Now let’s talk about TomoX: The DEX Protocol
TomoX is an upcoming DEX Protocol that allows anyone to launch their on permissionless Decentralized Exchange in minutes. It requires very little technical knowledge making it a near turn-key solution.
TomoX is the fastest DEX experience since it’s a Layer 1 protocol. This means it’s run and secured by the entire TomoChain network. Our Masternodes manage the DEX instructions directly, rather than other DEXs that operate as a Layer 2 protocol. What this means is TomoX DEXs will operate at about 50x faster than a typical 0x exchange. That significantly improves the end-user experience.
TomoX DEX operators have access to a shared liquidity pool across all DEXs. That means a user buying on one DEX can be matched with a user selling on another DEX. Of course, Operators can customize and choose which tokens to include.
TomoX is fully decentralized since the Order Book is on-chain. Many other semi-decentralized exchanges store the OB on a centralized service in order to speed up the execution. That means there is a centralized point of weakness for them. TomoX minimizes custody and security challenges that centralized exchanges have too since all users are always in possession of their assets.
TomoX is currently in testnet and you can checkout TomoChain’s own DEX, aptly called TomoDEX, here: https://dex.testnet.tomochain.com/
Here is a link to get some free Testnet TOMO that can be used on the testnet version of TomoDEX: https://faucet.testnet.tomochain.com/
And finally, there is TomoP: Privacy Suite - TomoP is currently in testnet and is going to be the FASTEST way to send tokens privately. 2-4 seconds fast!
Any token issued on TomoChain will be able to utilize TomoP to send privately and anonymously. And that’s not all. We are including access to wrapped BTC, ETH, USDT, and other tokens that can also utilize the blazing speed and privacy that TomoP will offer.
Dapp privacy is a major part of TomoP. It is going to allow for the creation of Dapps to be built to handle customer data with true privacy, including from the Dapp operators themselves. This can jumpstart a new wave of applications geared towards hiding user information, transactions, assets owned, etc.
We are issuing a new token standard (TRC21p) which will be purely private. The only data available will be on its token supply. Token issuers can optionally provide auditing access to enforcement authorities to meet regulatory compliance. What this means is if the next Global PayPal/Skrill/Alipay competitor can build their service right on TomoChain and meet the most basic criteria required to stay above board in many jurisdictions.

Questions from the host
1. It’s been stated that TomoChain was on track to be a cash flow positive business, is it currently cash flow positive? What services or products is it offering to bring in this revenue?
Yes, absolutely. Our plan is to be cash flow positive this year. This really goes back to the level of experience our executive team has. Everyone is seasoned, having come from different fields, in big business and startups. Before the crazy boom of ICOs and IEOs, raising funding for traditional startups required considerable proof that there was market fit, that there were actual customers to drive revenue, and a model for growth.
We knew that TomoChain’s funds raised during the ICO were for a space that has yet to prove itself so the company had to be smart in budgeting for an uncertain future. And part of that initial preparation was selling much of the ICO proceeds into fiat. Something MANY blockchain startups did not do, largely due to ambitious teams that are also headed by very inexperienced leaders. So while the bubble burst, we had capital to continue operations and to even scale it.
And, we ARE running a business. A sustainable business requires us to identifying areas to generate income in order to minimize risk and to sustain the business in the long term. So we do both consulting and services work by helping clients to develop wallets, launch tokens (Orbyt), build exchanges (AIS), and of course enterprise solutions on the blockchain of which we have clients based out of Japan and in the Middle East using blockchain for traceability solutions across various industries from automotive, healthcare, and food.
2. What is the most strategical step TOMO is doing to bring adoption of TOMO coin to our daily lives?
Empowering businesses with a truly scalable blockchain that can be used by thousands and millions of users. We see user adoption of blockchain coming from businesses that base their solutions on blockchain technology. And, TomoChain has a number of real income-generating companies that have built on us, from exchanges to payment services to enterprise clients. Not bad for 1 year I say, especially during a stagnant market. Here are some examples.
UcarPac – A Top 10 User Car company in Japan is building traceability solutions on the blockchain. We completed a POC at the end of last year. After the assessment, the client decided it was solid and commissioned Phase 2 to expand the development of the project for commercialization purposes
Triip Protocol – Triip is a destination service for travelers to book vacations powered by Blockchain. Triip is a Shark Tank Vietnam alumnus, and the first ICO on TomoChain. Users can book tours and staycations using Triip or TOMO tokens.
WisePass – A service that sells subscription services to get discounted Starbucks, Singha Beer, and even makeup (of all things) integrated TomoChain as a payment solution
“Undisclosed Vendor” – Soon to be announced, a large player in the corporate gift giving business is also launching a Dapp on TomoChain to allow for them to make purchases with TOMO across thousands of items.
Maka - A peer-to-peer marketplace to conveniently buy/sell TOMO and other blockchain tokens using standard payment gateways, including e-wallets and bank transfers.
Coin98 – A local Vietnam crypto media company launched an App to allow for their community to earn their TomoChain token called C98 and use it for products and services geared around investors and gamers. The reception has been HUGE. 95,000 users and generating 500K+ transactions on our blockchain within 3 months of their launch! They are proving that innovative new business models can be adopted relying on and being blockchain specific.

3. Do you have any plans to collaborate with developers or attract more Dapps built on TomoChain?
We are today. Our founders run the largest Blockchain Developer community in Vietnam and we work with a number of them to help develop solutions on the blockchain.
Our team has held Hackathons a few times over the last couple years and we have done developer workshops too, including one with Neo Blockchain. And this year we are working closely with educational institutions to launch blockchain courses in Vietnam.
Every Dapp developer we work with is a partner. We try to provide as much support as possible, both technical and marketing. A number of Dapps are games on TomoChain and we hold contests regularly to promote the developers and their titles.
Since we are focusing on alleviating the friction of blockchain technology, we are building out an API that will make it even easier for developers to integrate blockchain into standard applications. This is intended to allow standard non-blockchain application developers to operate in an environment they are accustomed to while also having the benefit of blockchain technology accessible.
Onboarding more developers will take time. However, I’m confident we’re on the cusp of something wonderful in the coming years that will change the relationship between users and applications enabled by blockchain. Entirely new economic structures can be set up since it’ll be the users owning all of their data for the first time in digital history. And true ownership is a powerful motivator that can be harnessed by innovative blockchain businesses.

MarcoPoloProtocol #2 #AMA Summary: #AMAwithKenny - How Marcopolo Protocol Designs a New P2P E-cash System?

MarcoPoloProtocol #2 #AMA Summary: #AMAwithKenny - How Marcopolo Protocol Designs a New P2P E-cash System?
#AMAwithKenny
On February 21, MarcoPolo Protocol hosted the second online AMA on MarcoPolo Protocol English Telegram group (https://t.me/MarcoPoloMAP) and they invited MarcoPolo Protocol Core Developer Kenny as our guest to answer questions from the community.
Here are the highlights from the AMA event.
#AMAwithKenny Question 1: Please introduce yourself to everyone, also, could you tell us what is MarcoPolo Protocol?
Hello everybody, I’m Kenny. I got into the field of blockchain at the end of 2016, mainly working on the research and development of public chain consensus protocols. At the moment, I’m a core developer of MarcoPolo Protocol.
MarcoPolo Protocol is an open-source blockchain protocol strategically invested by Softbank. It is a new peer-to-peer electronic cash system infrastructure and aims to achieve shared resources and intelligent inter-chain scheduling and contribute to decentralized applications with better scalability and lower transaction fees among the global blockchain networks.
#AMAwithKenny Question 2: Please describe the progress of your project in the past year.
From the perspective of funding and partnership, Marcopolo protocol was caught sight by Softbank last year and got Softbank investment, followed by being listed on the renowned exchange Kucoin. Its partners range from the global international electronic payment company Ksher , as well as a strategic partnership from several chains including fundamental developer forces and industrial resources.
According to the first step of the road map, gravity has been implemented. It is a central component, and currently supports the resource sharing of truechain and Ethereum
Based on gravity, DAPP Marcopay and POB community governance DAPP are implemented.
Building a technology community and interacting with developers through online AMA, discord, and riot has attracted many developers' attention to map.
At the beginning of the development of POC-1, the consensus, output block and RPC module of POC-1 are constructed based on the rule language.
In terms of product and applications, MarcoPolo protocol has already implemented a wallet application called MarcoPay, which is used widely in the community. Roughly 70,000 users and community members at the moment. And it's growing rapidly.
We have cooperated with a company named Ksher, a global electronic payment company. At present, payment in some stores has been implemented in Thailand.
We have developed communities of over 70000 people, covering South Korea, Nigeria, India, Vietnam, Indonesia, Turkey, Brazil, Australia, Russia. Also,our token has been listed on CoinMarketCap and Coingecko.
#AMAwithKenny Question 3: Compared to Polkadot and Cosmos, what are the distinct and innovative parts of MarcoPolo Protocol? Is it still necessary to develop other public chains?
Polkadot empowers blockchain networks to work together under the protection of shared security; Cosmos is a decentralized network of independent parallel blockchains and powered by BFT consensus algorithms like Tendermint consensus.
Similar to the other two projects, MarcoPolo Protocol could improve the scalability and interoperability of the blockchain network.
The main differences are the properties of shared resources and intelligent inter-chain scheduling. This is MarcoPolo Protocol’s innovation.After Satoshi Nakamoto proposed the p2p e-cash system, various public chains proposed a variety of solutions in order to accomplish the p2p payment without a third party. With the future popularity of digital encrypted currency payment and exchange, increasing TPS is highly demanded. Relying only on a single chain to process transactions would not significantly improve the processing speed. Therefore, more chains are needed to perform collectively in order to achieve TPS sharing.
MarcoPolo Protocol intends to provide a convenient and economical way of p2p payment while fully utilizing resources from different blockchains.
#AMAwithKenny Question 4: Why do you join MarcoPolo Protocol? What attracts you the most?
MarcoPolo Protocol is an open-source community, which is formed by a large number of blockchain open source technology enthusiasts and professionals. People applied their expertise and innovative ideas in many perspectives such as theoretical research, promotion, coding, system engineering, etc.MarcoPolo Protocol is committed to creating a new peer-to-peer electronic cash system that truly fulfills the vision of Nakamoto.
#AMAwithKenny Question 5: Can you tell us more about how MarcoPolo Protocol achieves resource sharing among chains? What is the mechanism to accomplish intelligent inter-chain scheduling?
Good questions, let me answer them together.
In terms of sharing resources across chains, in MarcoPolo Protocol, we select the appropriate synerchain as the target isomorphic chain to process transactions and then realize the TPS sharing of synerchains through the MTP protocol;
MarcoPolo Protocol selects a secure, efficient, and low-cost third-party public chain as the target heterogeneous chain, and then uses the computing power of the target chain to deal with transactions. The process requires the related interact-chain to interact with the target chain through BRPC and then moving applications and transactions to the target chain in order to finish the transactions. Therefore, the target chain is considered as Layer 2 and processes the transactions in MarcoPolo Protocol. In this way, the TPS capacity of the whole MarcoPolo Protocol network can be expanded by stacking multiple target chains.
Intelligent scheduling across chains is the core of MarcoPolo Protocol. We wish to build interactions across chains through MTP+BRPC, so as to solve the problem of inter-chain interoperability.
**#AMAwithKenny Question 6: As most people know, the ecosystem determines the future of public chains. How does MarcoPolo Protocol think about its ecological construction?**First of all, I highly agree with the significance of the ecosystem for public chains. We believe that there is a natural demand for payment, exchange, and borrowing of digital cryptocurrencies in the future.
MarcoPolo Protocol primarily targets three application scenarios: Dpayment, DEX, and Defi. We are building an E-cash system infrastructure that will serve the whole blockchain ecosystem.
In the electronic cash system, DEX and Defi are two important applications. Currently, DEX and Defi are structured in a single chain or ecosystem. We wish that DAPPs built on MarcoPolo Protocol could share DEX and Defi achievements of other ecosystems.
#AMAwithKenny Question 7: How many people in the MarcoPolo Protocol team?
Now the team has more than 30 people, more than 20 developers, 5 marketing staff, 7 operating staff, and distributed offices in many countries. They come from Singapore, Thailand, South Korea, China, Australia, Brazil, Indonesia, Turkey, and other countries.
#AMAwithKenny Question 8: What does the technical roadmap look like and what more is coming from MarcoPolo Protocol? At which development stage is it in right now?
MarcoPolo Protocol Road Map:The First Phase 2019.Q1Gravity: the interoperability module Gravity has been developed, which realized useable interoperability between third-generation public chain and high consensus digital currency such as BTC and ETH, will share computing power and performance gradually expand to more high-performance public chain through interoperability.The Second Phase 2019.Q3 Electromagnet: Online retail payment application - MarcoPay POB Community Governance DAPP.The Third Phase 2020.Q4Interaction: Independently developed MarcoPolo main Network StandardChain will be launched, achieving APoS, On-chain governance, Architecture design of InteractChain.The Fourth Phase 2022.Q2Grand Unification: The realization of heterogeneous cross-chain operability, resource sharing between chains. At present, core team members concentrate on the research and design the protocol. StandardChain is still in its early-stage proof of concept.
Also, during this stage, we launched MarcoPay DAPP. You can download it here and use it:
https://www.marcopolopay.org/download
In addition, we are having an Airdrop activity right now (https://t.me/MarcoPay_Airdrop_Bot), you can join it and win MAPC and swap your MAPC to MAP on MarcoPay APP
#AMAwithKenny Question 9: MarcoPolo Protocol technical community has attracted developers from Bitcoin and Cosmos. Could you please talk about how to participate in the technical community?
MarcoPolo Protocol technical community encourages researchers, technology evangelists, and developers to participate. After the protocol passed through the PoC phase and was able to be implemented in modules, we definitely need more developers to join the community. After sorting out the research topics, we will share with everyone on the Discord and Riot channels in our technical community.Click the link below to join the community to know the up-to-date progress and take part in the discussion.Discord: https://discord.gg/KTJ2QzcRiot: https://riot.im/app/#/room/#MarcoPolo:matrix.org
**#AMAwithKenny Question 10: Developers are essential to the development of the technical community. Could you please tell us what are the incentives of MarcoPolo protocol in this regard?**Regarding the motivation mechanism, as far as I know, MarcoPolo has set up a pool of 9% of MAP for incentives to the technical community. The incentives are mainly used in two aspects: technology and community.
Technology has three parts: research, technical promotion, and development;
Community includes online AMA, Meet-ups, Workshops, etc. MarcoPolo Protocol has been actively exploring ways to motivate great and talented people to get involved in this open-source project through different levels.
#AMAwithKenny Question 11: What’s the advantage of MarcoPolo Protocol’s APoS consensus? What are the advantages and disadvantages compared with PoS? And what problems APoS has solved?
APoS is an Assets Proof of Stake consensus algorithm. There are three advantages:
  1. It supports multiple digital cryptocurrency staking, more people can participate in the ecosystem
  2. it can protect assets, people are still keeping their original BTC or ETH, they just staked into APoS system
  3. It solves the problem of easy centralization in the traditional PoS/DPoS consensus mechanism
#AMAwithKenny Question 12: Are there any new products coming out soon?
Good questions, there is an exciting product coming up soon
We are launching a new build-in product Milione in 5 days.
I can share some of its features:
  1. You can deposit MAP to earn USDT
  2. The yield rate is higher than most of the products on the market
  3. No lock-up, you can withdraw your asset anytime you want
  4. Profitable referral mechanism, you can invite your friends and earn money with them together.
Besides products, there are many more partnerships coming up, we have reached many other famous companies and exchanges. Please stay tuned, once it is confirmed, we will announce it in this group and our twitter.
#AMAwithKenny Bonus Question 1: Is there anything you want to say on the MAP piece?
Let's wait and see
#AMAwithKenny Bonus Question 2: What payment scenario do you have so far? Where can I use it?
We have launched MacroPay DAPP, you can download it here:
https://www.marcopolopay.org/download
This DAPP can manage digital assets on multiple chains simultaneously, providing a "safe, professional, decentralized" solution for global online and offline product payments. You can use MarcoPay to shop in some stores in Thailand, and more shops will support MarcoPay in Southeast Asia, South America, Africa, Europe, and other countries.
#AMAwithKenny Bonus Question 3: What payment scenario do you have so far? Where can I use it? What is Kenny’s opinion on the future for MacoPolo Protocol Token and what are the most difficult challenges he encountered during the development of MarcoPolo Protocol?
MAP is planning to open more than 1000 retailer shops to do peer to peer payment transactions in 2020 across Brazil, Turkey, Indonesia, Korea, and Thailand. MAP has a strong technical team including developers and researchers around the world to make sure the project will be delivered in high quality and in time.
#AMAwithKenny Bonus Question 4: What’s the business model of MAP? Is building another public chain? Or you want to charge fees for the applications hosting on the chain? How do you make the business sustainable and profitable in the long run? How much return you expect to be able to get in 2-3 years of time frame?
Marcopolo protocol p2p electronic cash infrastructure will enable Defi, Dpayment, Dex applications. Successful applications will help to boost the on-chain ecosystem under MAP infrastructure. And applications who make profits will feedback to the community in the means of MAP token only. We will make sure the community and application developers win-win together then we can achieve a long term success.
MAP since listed in Kucoin 3 months ago has already gained 4 folds. We are pretty sure the token price will go up further according to the current strategy.

Establishing a smart contract commercial scenario: Chainlink, Zk-Snarks and sharding technology work together to make the ultimate killer

https://medium.com/@rogerfeng/making-smart-contracts-work-for-business-how-chainlink-zk-snarks-sharding-finally-delivered-8f268af75ca2
Author: Feng Jie translation: Liu Sha
“The highest state of technology is to integrate into the various scenes of everyday life, to fade away from high-tech outerwear and become a part of everyday life.” – Mark Weiser
People in the future will not even think that smart contracts are "innovative." By that time, smart contracts would permeate every aspect of life, and people couldn't even imagine what the era of non-digital currency would look like.
Later historians may divide human business history into two eras, the pre-smart contract era and the post-smart contract era. After all, digital money has brought unprecedented changes to the nature and patterns of business practices in the real world. An anonymous member of the Chainlink community once said: "Smart contracts can change the DNA of the business."
Of course, like all the technological revolutions of the past, smart contracts also need to reach a "tipping point" to truly achieve large-scale applications. So we need to ask ourselves two questions:
  1. What exactly is this so-called tipping point?
  2. As of August 2019, have we reached this tipping point?
To reach the tipping point means unlocking the ultimate nirvana of business.
Tipping point We can think about this issue from the perspective of mainstream companies. Imagine what a perfect smart contract platform should look like. What characteristics should this platform have? Or what features must be possessed?
To reach the tipping point, you must establish a public chain with the following four characteristics:
  1. Privacy protection
  2. In addition to the cryptocurrency, the transaction can also be settled in mainstream legal currency and comply with the regulatory requirements of financial markets such as ISO 20022.
  3. Achieve scalability without sacrificing decentralization or security, that is, solving the "impossible triangle problem."
  4. Connect the external data under the chain, that is, solve the "prophecy problem."
Now that we have Chainlink, zk-snarks and sharding technology, we have reached this tipping point.
Next, let's explore how this ultimate nirvana is actually made. Our discussion will be mainly from the perspective of Ethereum, which is still the top smart contract platform for community size and mainstream applications.
So what about the private chain?
Before delving into it, I want to take the time to solve an unavoidable problem. The mainstream view has always believed that the private chain is a more suitable solution for the enterprise. Therefore, we first dialectically analyze the two advantages and two major drawbacks of the private chain.
Disadvantages
  1. Centralization leads to relatively lower security
It's not surprising that IBM and Maersk's blockchain freight alliances have a hard time finding customers who are willing to join. How can other freight companies be willing to let their biggest competitors (Maersk) verify their trading data? Only madmen dare to do this.
  1. The staking of the horses occupy the hills:
This problem is even more serious than centralization. John Wolpert, co-founder of the IBM blockchain, wrote an excellent article called Breaking the Barriers to Realize Security: Why Companies Should Embrace the Ethereum Public Chain, which he covered in detail in the article.
If every company builds its own private chain, it will lead to chaos in the mountains. Today's B2B ecosystem is very complex. Imagine the innumerable private chains of the world intertwined to form a huge "spider web." This is not only cost-effective, but also not scalable.
The starting point of the blockchain is to break down barriers instead of building more barriers.
"One day, one of your big buyers called you to ask if you want to join their private chain. You promised. The next day you received a call from the wholesaler to ask you the same question. Then came the supplier, freight. Business, insurance company or even bank, and each company may have several private chains! Finally you have to invest a lot of time and cost to operate dozens of blockchains every day . If there are partners to let you join them at this time The private chain, you might say "Forget it, or fax me the order!" ”—Paul Brody (Ernst & Young)
“Every time you connect two private chains through a system integrator, you have to pay a lot of money .”
Advantage
  1. Scalability: With the Ethereum public chain implementing fragmentation technology, this advantage is rapidly shrinking.
  2. Privacy protection: At this stage, the classification of public chain / private chain is actually not very accurate. The Aztec , Zether, and Nightfall protocols (both based on the zk-snarks protocol) effectively provide a "private chain model" for the Ethereum public chain, allowing it to switch between the public and private chains. Therefore, a more accurate classification should be the alliance chain and the public chain.
By 2020, the label of the public chain/private chain will gradually disappear. The public and private chains will no longer be two opposing concepts. Instead, the concept of publicly traded/private transactions and confidential contracts/open contracts is changed, and the scope of these transactions and contracts varies according to specific needs, either bilaterally or multilaterally or even publicly.
All in all, the private chain has two major drawbacks compared to the public chain. Not only that, but the two major advantages of the private chain are also rapidly disappearing.
“Technology will evolve over time, so there will be a variety of solutions to solve existing problems. Ultimately, the public-chain platform will have the same performance, scalability and data privacy as the private chain, while at the same time ensuring security and Decentralized."
Feature 1: Privacy protection (predictive machine and public chain privacy)
Enigma founder Guy Zyskind once joked in his MIT graduation thesis that smart contracts can only become commercially valuable if they become "confidential contracts." He later proposed that zk-snarks and Trusted Execution Environment (TEE) are the most promising solutions. He said nothing wrong.
What is zk-snarks ? Zk-snarks is a zero-knowledge proof mechanism (ZPK). So what is the zero-knowledge proof mechanism? In short: a zero-knowledge proof mechanism allows you to prove that you own certain information without revealing the content of the information.
Vitalik Buterin explained this concept in detail from a technical point of view in an article published in 2017. Hackernoon also wrote an excellent article explaining the concept in an easy-to-understand way with the example of a five-year-old child and Halloween candy.
What is the trusted execution environment? The trusted execution environment lets the code run on closed hardware, and
1 ) The guarantee result cannot be tampered with
2 ) Protecting absolute privacy, even hardware running code can't get confidential information.
The most well-known trusted execution environment is Intel SGX. Chainlink has established a partnership with Intel SGX after acquiring Tom Crier.
Ernst & Young released the Nightfall agreement on Github on May 31, 2019. A well-known accounting firm with a history of 100 years will choose to add privacy features to the public chain instead of developing a private chain. This is a problem.
Since then, the community has been actively developing on this basis, not only to improve the code, but also to develop a plug-and-play Truffle Box for those who are not good at writing code. Blockchain communities and businesses generally rarely collaborate, so these collaborations fully demonstrate the popularity of Nightfall.
Prior to this, two zk-snark-based Ethereum public chain privacy protocols were introduced, namely AZTEC (Consensys) and Zether (Stanford, JPMorgan Chase). An obvious trend is slowly taking shape.
In the field of oracles, Chainlink uses both zero-knowledge proof and a trusted execution environment to complement each other. Trusted execution environments guarantee data privacy, even for nodes that cannot access data (this feature is critical for bank accounts and API keys).
Chainlink is still trying to implement a trusted execution environment, and nodes can access data temporarily, so authentication services are also needed. Although the credible execution environment is almost 100% foolproof, in theory, a strong shield has a spear that can penetrate it. Therefore, the team is currently trying to run zk-snarks in a trusted execution environment (Thomas Hodges mentioned this in the 2019 Trufflecon Q&A session). The combination of the two can form a very robust and complete system. The attacker must find a way to strip all the layers of an onion at the same time to make any effective attack (and it is already difficult to peel off a layer of skin).
“Chainlink combines a trusted execution environment with zero-knowledge proof to build what we call a defense-in-depth system, which means they provide all the tools needed for smart contract developers, including trusted execution environments, multiple nodes, and Data sources, fine margins, reputation systems, asymmetric encryption, zero-knowledge proofs, WASM, and OTP+RNG, these features allow smart contract developers to adjust the confidentiality and cost of contracts based on specific budget and security needs. Machine, Chainlink and its four major application scenarios》
In the future, zk-snarks may be upgraded to zk-starks (a fully transparent zero-knowledge proof mechanism) that protects the system from quantum computer attacks. And the best thing about zk-starks is that it's more scalable than zk-snarks. In other words, it can better protect privacy, and the cost of gas will not increase.
If you want to learn more about zk-starks, you can read a popular science article written by Adam Luciano.
Feature 2: Scalability (scalability of predictive machines and public chains) To understand this problem, we can make an analogy like this:
A public chain is like a large enterprise, and every employee (ie, a node) must attend each meeting (ie, confirm each transaction). Imagine how inefficient this company is! Only customers who have a lot of money (ie gas fees) can get their requests to the forefront. And this is not the most serious problem. The most serious problem is that the more employees (ie nodes) who join the company, the harder it is for the company to function properly! In the end, the company not only failed to expand linearly, but also became smaller and smaller. Although this guarantees decentralization and security to the greatest extent, the price is completely abandoning scalability.
There are various temporary fire fighting solutions, but no one solution can completely solve this "impossible triangle problem." For example, EOS uses the DPOS mechanism (share authorization certification mechanism), where only 21 super nodes (many of which are well-known nodes) are responsible for verifying all transactions.
Sidechains (such as Bitcoin's Lightning Network and Ethereum's lightning network) guarantee scalability and decentralization at the expense of security.
So how to use the fragmentation technology to solve this problem? Let's make another analogy:
In reality, there is only one company that is not too much to ask everyone to attend all meetings, that is, small start-ups (that is, private chains that limit the number of nodes).
In most cases, large companies divide employees into thousands of teams (ie, shards), and each team's principal (ie, the certifier) ​​is responsible for reporting to the senior management (ie, the main chain). If people from different teams need to collaborate (and sometimes also), then they can collaborate by cross-shard receipts. If a new employee joins the company, the team can be re-segmented (ie re-sharding). This allows for linear expansion.
In fact, the process of developing a start-up to a large enterprise is surprisingly similar to the process of Ethereum 1.0 developing into Ethereum 2.0.
“The Ethereum 1.0 period is that several people who are alone are trying to build a world computer; and Ethereum 2.0 will really develop into a world computer.” Vitalik Buterin said in the first piece of the workshop.
Since Ethereum was not originally built on the principle of fragmentation, it takes seven steps to achieve the goal (this is a bit like the word morphing solitaire game). The first step is planned for January 3, 2020.
At the same time, developers can use many other blockchain platforms designed based on the fragmentation principle. Some platforms, including Zilliqa and Quarkchain, are already compatible with Chainlink.
If you want to see more in-depth technical analysis of shards, check out an article by Ramy Zhang.
In the field of oracles, Chainlink has the following two characteristics:
1 ) Use Schnorr threshold signatures to quickly reach consensus in a cost-effective manner. The next version of the chain only needs 16,000 gas.
2 ) We have previously discussed the need to use trusted execution environment hardware to ensure that nodes cannot access sensitive data. Since you have hardware in your hand, you can use it to do some actual computing work, so that you can properly reduce the amount of computation on the smart contract platform.
"With the SGX system (Town Crier) and zero-knowledge proof technology, the oracle can be truly reliable and confidential, so the boundaries between the oracle and the smart contract are beginning to flow... Our long-term strategy... is to let The predictor becomes the key chain of computing resources used by most smart contracts. We believe that the way to achieve this goal is to perform chain operations in the oracle to meet various computing needs, and then send the results to the smart contract."Chainlink White Paper, Section 6.3 (26 pages)
Of course, this “long-term strategy” has certain risks, unless Chainlink can implement a trusted execution environment and its service provider ecosystem can achieve a qualitative leap. However, the Chainlink team's vision is absolutely forward-looking: under-chain computing is a key factor in ensuring that blockchains are not dragged down by large amounts of IoT data.
The Internet of Things has dramatically increased the current state of big data. At present, most of the data is still generated on the software side, and it is not real-time data, and most of the data in the future will be real-time data generated on the sensor side. One of the big drawbacks of real-time data is that it increases storage pressure. For example, Coughlin Associates expects an unmanned car to generate 1G of data per second. This means that the same car will produce 3.6T data per hour!
The only viable solution is to do real-time analysis of the data, rather than storing the data first. In the Global Cloud Index: 2016-2021 Forecast and Methodology White Paper, Cisco predicts that more than 90% of data in 2021 will be analyzed in real time without storage.
That is to say, the essence of data is that it can only exist in just one instant. The nature of the blockchain is not to be modified, so the two are as incompatible as water and oil.
The solution is to analyze the raw data under the chain, extract the meaningful results and send them to the blockchain. The combination of fragmentation technology and trusted execution environment forms a new computing architecture, similar to the cloud computing-fog computing-edge computing architecture.
It should be noted here that it is good to improve computing power, but this is not the main purpose of the blockchain.
The fundamental purpose of the blockchain is not to reduce the original cost of computing and data storage. After all, technology giants such as Amazon, Microsoft, Google, Salesforce, Tencent, Alibaba, and Dropbox have built world-class cloud services. The centralized server wins high computational efficiency (but the blockchain will greatly improve the computational efficiency through fragmentation technology, and will catch up with it one day). The value of the blockchain is to reduce the cost of building trust. Nick Szabo calls it "social scalability" (this is a relative concept to the "operational" scalability we have been talking about). Vitalik Buterin also made it clear that the meaning of smart contracts is to accept small arithmetic delay penalties in exchange for a substantial reduction in "social costs."
Alex Coventry of the Chainlink team once raised the question: "We have missed many opportunities for cooperation and reciprocity because we can't confirm whether the other party will fulfill the promise?"
Is there any potential for data storage projects like Siacoin and IPFS? What about decentralized computing projects like SONM and Golem?
Siacoin 's core value proposition is not that its computing efficiency is higher than traditional cloud services. The cost of computing is required to split, repeat, and reassemble data. And companies are more capable of buying the latest and greatest hardware than individuals. Siacoin's core value proposition is to process data in an Airbnb-like mode, so management fees will be lower than traditional models. It also generates additional social value, such as flood control, privacy and security, and anti-censorship.
The same is true of Golem and SONM. Even with the most efficient protocol, it is inevitable that a small amount of delay will be imposed and fined to coordinate the hardware of different geographical locations. Therefore, under the condition that all other conditions are equal, the centralized hardware still has the advantage of faster computing speed. However, the core value proposition of the above project is to use the Airbnb-like model to reduce management costs.
We must strictly distinguish between "social scalability" and "operational scalability", and the two cannot be confused. I will explain these two concepts in detail when I discuss "Magic Bus and Lightweight Library" later.
Feature 3: Compatible with legal currency
Most mainstream companies do not regard cryptocurrencies as "real currencies." In addition, even if someone wants to use cryptocurrency for trading, it is very difficult to actually operate because of its high price volatility. I discussed the “price volatility problem” in detail in Chapters 8 and 9 of the previous article. These problems do not completely erase the existence value of cryptocurrencies, because cryptocurrencies also have many advantages that legal currency does not have. I am just emphasizing what we need to know more about the comfort zone of mainstream companies.
Chainlink acts as a universal API connector that triggers open banking payments. Chainlink is fully compliant with ISO 20022 and has established a long-term partnership with SWIFT (it is worth mentioning that SWIFT has not been updated for a long time and hopes to be updated after the SIBOS 2019 conference).
PSD2 will take effect on September 14, 2019. All banks in the EU will all comply with this new regulation by then. In other words, the bank must put all account data in the "front end" and can be called through the API. The approved third party (ie, the Chainlink node) can trigger the payment directly without the payment service provider.
Although the United States and Japan have not adopted similar laws, many banks still spontaneously promote the development of open banks. Banks open APIs to third-party developers to create new revenue streams and customer experiences that ultimately increase profitability. In addition, this will allow banks to better respond to competitors in the mobile payment and financial technology sectors in an APP-centric economic model.
As this open banking revolution continues, Chainlink will connect smart contracts with the world's major currencies (US dollar, euro, yen, etc.).
Only one external adapter is required to connect to the authenticated API. From a programming perspective, it is relatively simple to allow everyone in the community to contribute code to the code base (and thus achieve scalability). Chainlink has released adapters for PayPal and Mister Tango (European version of PayPal).
Feature 4: Data connection with the chain
Chainlink has been working on solving the "prophecy problem" and successfully succeeded on the main online line on May 30, 2019.
Chainlink has made many achievements in just a few months. Provable (formerly Oraclize) was successfully used on the Chainlink node and finally settled the debate about whether the predictor should be centralized or decentralized.
Synthetic Ether lost 37 million Ethercoins in a hack because it did not connect to Chainlink. Fortunately, the money was finally recovered and did not cause any loss. This lesson illustrates the importance of decentralized oracles.
In addition, both Oracle and Google have partnered with Chainlink to monetize their API data and create a virtuous circle to capture the market opportunities that Facebook missed.
There are new nodes coming online every week, and the network activity has been very high. The Chainlink team maintains a list of certified nodes in the documentation and Twitter releases. Twitter user CryptoSponge also set up a new development for the Tableau push update Chainlink team:
Regarding the importance of the current stage in the history of blockchain development, Brad Huston summed it up very brilliantly:
"The biggest problem with cryptocurrencies is to build bridges between cryptocurrencies, fiat currencies and big data. Chainlink is very beautifully narrowing the distance between the three. Now it can even be said: 'The bridge has been built.'"
Magic bus and lightweight library
Let's summarize what we discussed earlier. The real purpose of the blockchain is to reduce the cost of building trust and achieve "social scalability."
Therefore, according to this logic, the main application scenarios of platforms such as Ethereum 2.0 and Zilliqa should be in the B2B field. I quote a sentence I wrote in a previous article:
“My conclusion is: If the smart contract is successful, it will also succeed in the B2B field first.”
The private chain itself is self-contradictory and destined to fail. It has led to the phenomenon of occupying the hills, thus increasing the social cost, which is in opposition to B2B itself, and ultimately it is self-restraint. ”
Before the emergence of fragmentation technology, even simple games (ie, etheric cats) could not be smoothly run on the public chain, let alone dealing with complex B2B contracts and even changing commercial DNA. With the sharding technology, everything is ready.
Despite this, we can't use Ethereum 2.0 as an all-powerful platform. Just now we said that although it is a good thing to speed up the calculation, this is not the real purpose of Ethereum 2.0. And before we also said that due to the irreversible modification of the blockchain, it is not good to deal with a large number of fleeting real-time data of the Internet of Things. In other words, we must be soberly aware that Ethereum 2.0 will not replace traditional web 2.0. Instead, we should make better use of the real advantages of Ethereum 2.0:
“There is a new concept now, that is to think of the Ethereum main network as a global bus... We use the Ethereum 2.0 main network to treat various business resources as a working group on Slack: it can be easily built and integrated. And restructuring. The SAP inventory management system in your company, the dealer's JD Edwards ERP system, and the financial technology partner's tall blockchain system can seamlessly interface, eliminating the need to develop an infrastructure specifically for each partner." - John Wolper describes his ideal "magic bus"
Ethereum 2.0 should be an integration center, not a data center or computing center. It should be a library built specifically to store B2B contract terms (to be honest, even with fragmentation technology, the amount of data is large enough).
We should not expect Ethereum 2.0 to be an all-powerful platform, but rather develop it into a "lightweight library."
If we reorder the pyramid model just now, the architecture of the magic bus is obvious:
Of course, the positional relationship in the above model is not static. With the development of 5G technology, edge computing and IoT sensors, they may bypass the cloud to directly interact (or even bypass the fog end). If the collaboration between Iotex and Chainlink is successful, then the edge can interact directly with the trusted execution environment.
Time will tell if Airbnb's shared data storage and computing model can make management costs lower than the current mainstream Web 2.0 model. Time will also prove whether the market really needs anti-censorship, anti-tampering, security protection and privacy protection. Do users really care about these social values ​​and are willing to pay for them? Do they think these are just the icing on the cake or the most fundamental value?
in conclusion
Whether it is the battle between web2.0 and web3.0 or the battle between cryptocurrency and legal currency, one thing is beyond doubt:
We have reached the tipping point, and the era of smart contracts with commercial value has arrived.
In fact, the only problem at the moment is the time issue, and the main roadblocks have been basically cleared.
  1. When will Ethereum 2.0 finish these 7 stages and be officially released?
  2. When will Chainlink use a trusted execution environment on a large scale? If the cooperation between Intel SGX and Town Crier fails, what alternative plans are there? Will Chainlink communicate with other blockchain teams that plan to use a trusted execution environment (such as Dawn Song's Oasis Labs)?
At present, the main technical problems in the ecosystem have been solved, and now it is only necessary to recruit a group of enthusiastic developers to do the work of “connecting the line”.
Digital currency has changed commercial DNA, and the future is full of possibilities.
The only thing that hinders us now is our own imagination. The future is infinitely imaginative, and the future will be the world of developers. Dapps is already overwhelming. There is no doubt that we have found the ultimate nirvana.
