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!

What are the benefits of Crypto Mining?

What are the benefits of Crypto Mining?

https://preview.redd.it/q6xfuxvtmjv41.png?width=875&format=png&auto=webp&s=b092bca718f6cba3ae8c327a54952f4e65c7ed25
If you’ve ever heard the word cryptocurrency, then you’ve probably heard about the mining as well. If you still don’t know what cryptocurrency mining is and about profitable, keep reading!
In order to understand crypto mining, you need to fully understand what a cryptocurrency is first. Unlike traditional currencies (aka fiat currency), a cryptocurrency is a digital asset that works in a decentralized way; it does not require a bank or a third-party to operate. Someone can send someone else a cryptocurrency directly without any third-party involved.
The first ever cryptocurrency created was Bitcoin.
Every single cryptocurrency has a blockchain, which is an immutable digital ledger. A single transaction is recorded on the blockchain permanently, which no one can edit or delete it randomly.
A blockchain works by incentivizing miners to confirm the authenticity of each transaction. A person who confirmed the authenticity of the transaction, get the cryptocurrency as a reward.
Since the cryptocurrencies are based on cryptography, the miners need to solve extremely complicated mathematical problems to verify each transaction. They are incentivized to do it because they are rewarded for it.
Anyone can participate in mining from anywhere in the world as long as they have a computer. When the number of miners increases, it allows cryptocurrencies to be more secure. Even if an attacker would want to attack the blockchain network, somehow, an attacker needs to know 51% or more miners. Since the miners are spread around the world, this task is close to impossible and most likely not economically viable.

Types of Crypto Mining

Bitcoin was the first cryptocurrency to introduce the Proof-of-Work (PoW) consensus algorithm, where users have to solve complex mathematical problems in order to process transactions and secure the whole network.
Bitcoin was quite easy to mine at first, and you could do it with your CPU, there was no need for special equipment, and the rewards were huge. However, today, Bitcoin’s mining difficulty has increased considerably, and users need specialized and expensive equipment to mine it.
There are four main types of mining when it comes to the PoW algorithm. There is a CPU, GPU, ASIC, and Cloud mining.
The first three are essentially the same, but they use different parts of your computer. There are some cryptocurrencies specifically created to be mined only through CPU and to be ASIC resistant. Other cryptocurrencies can be mined through all three methods.
Cloud mining, on the other hand, is a process where a user basically pays to rent out a mining machine somewhere else. You don’t have to buy the equipment physically but it is wise to carry out due diligence and research into who and what you are paying for.

Proof of Stake ‘Mining’

With the introduction of the Proof-of-Stake (PoS) consensus algorithm, cryptocurrency mining changed forever. In this case, users don’t have to solve computationally intensive puzzles. In PoS-based cryptocurrencies, the creator of blocks is chosen via random selection or wealth.
Validators in the PoS consensus have to lock up some of their coins as a ‘stake’ and will get rewarded for it.
There are many benefits over the traditional PoW like lower cost and more energy efficiency. Additionally, because PoS encourages users to hold the coin in the wallet, it stabilizes the price a bit more than conventional cryptocurrencies.
Today, you can find plenty of exchanges that support staking, including the most popular exchange, Binance. The safest option, however, is always going to be staking using your own private wallet.

Proof of Formulation ‘Mining’

FLETA has developed the most innovative and newest consensus algorithms known as Proof-of-Formulation (PoF).
This PoF consensus algorithm uses something called the ‘Synchronization Group’, which allows all of the miners to mine in an orderly manner. The generating block time only takes 0.5 seconds, and the observer node checks the irregular blocks in real-time, which prevents the fork and double-spending. Furthermore, FLETA’s PoF algorithm is currently undergoing the patent process through the United States Patent Office (Application Number: 62717695).
The users can easily create a FLETA formulator through the official FLETA wallet. The minimum amount to create a single Formulator is 200,000 FLETA. The blockchain network is operated by FLETA and requires a 6-core CPU or higher.
As you created at least four Formulators, you will be able to upgrade it, which allows you to get 1.3 times more rewards.
Besides creating a Formulator, users can contribute to mining with a minimum amount of 100 FLETA.

Conclusion

Today, various mining methods exist, each with their pros and cons. However, cryptocurrency miners are still craving more convenient (and less costly) ways to earn rewards.
FLETA’s Proof-of-Formulation consensus is not only fast, but it is also highly secure the added layer of protection between observer nodes, formulator, and the synchronization group.
With plenty more to come, in terms of DApp development, games and partnerships, FLETA’s PoF is increasingly becoming the preferred consensus of many developers due to the speed, security and convenience of the platform.

Cocos-BCX:The decentralized gaming application & crypto assets creation platform

Cocos-BCX:The decentralized gaming application & crypto assets creation platform

I. Project Overview

Cocos-BCX is a platform used for the development, operation, management and transfer of decentralized applications and in-application assets on the blockchain ecosystem. The platform mainly includes three function modules:
(1)The application development framework that supports multiple operating systems and various blockchain environments.
(2)Completely scripted, componentized and data-driven application development tools;
(3)An improved blockchain system, which is oriented to high performance applications and based on graphene technology framework, and its related functional components.
Cocos-BCX can allow developers to perform programming, debugging, and publishing of decentralized applications oriented to the blockchain environment, and hybrid architecture applications. Meanwhile, the platform integrates the distributed user account system, wallet and digital asset circulation platform based on the blockchain, which can realize the permanent saving and cross-chain use of in-application assets.

II. Project evaluation

(一) Market analysis

1. Market conditions | 8 points

The organizing pattern of productivity dominated by governments in some areas or industrial domains is apt to change in the context of bottlenecks existing for global scientific and technological progress, rising resource consumption, an aging population, and intensified geopolitical conflicts. In particular, in 2008, when Nakamot published his thesis "Bitcoin: A Peer-to-Peer Electronic Cash System", discussions on blockchain and digital currency have gradually extended from technological aspects to economic, social and political, and other fields. The general public have begun to pay close attention to the impact of blockchain on social development as well as the role of digital currency in the world economy. Based on the decentralized characteristics of the blockchain and the vibrant vitality of the digital economy, the general public has enough confidence to predict that the decentralized "digital assets" will be a sweeping trend in the future, and will derive new business models and social values.
At the same time, in the development process of decentralized applications of different types, the game industry enjoys unique development advantages, because the game's production mode is the most sophisticated, enjoys the highest degree in terms of commercialization, and is one of the scenarios with the most profound foundation in terms of developers and users.
u Analysis: The game field has a huge room for development, which is highly consistent with the characteristics of the blockchain, and accords with the future development tendency of the digital economy.
The digital asset economy model carried by the project through the blockchain technology will assetize the content produced by the developer, enable the developer to continue reaping benefits during the use, management and transfer of his assets, and provide him with a convenient, decentralized game distribution channel; meanwhile, it helps players to transform the data formed by time and energy as well as the props they obtain as a result of their consumption into the assets that can be safely stored and circulated, offering players the right to manage and commercialize them.

2. Competition | 8 points

Since the last century till now, owing to the sustained efforts and promotion by a variety of IT technology game enterprises, the national and even global online game market is developing by leaps and bounds. If there is no systematic risks, such as policy regulation, vicious incidents and other factors, there will be no smooth and endless development momentum unless something unexpected happens. However, an objective analysis reveals that the current online game market is still dominated by IT technology companies, and even in a controlled and monopolized development, which, of course, also brings substantial profits, such as Tencent, Blizzard Tech.
u Analysis: It can be predicted that the Cocos-BCX project will hardly have any direct competitors in the strict sense for the time being, but will encounter a marginal pressure competitive environment from two dimensions. In summary, the classical IT game companies at home and abroad are massive in size and have obvious capital advantages. However, the Cocos-BCX project has an advanced philosophy and cutting edge technology, and thereby enjoys first-mover advantages for a breakthrough; The blockchain game project of the same business is currently marked by wide participation and generic applicability. But in comparison, the Cocos-BCX game industry has such advantages as a salient background, special project orientation and sophisticated development in technical modules, and therefore has greater development potential.

(二) Token Status

1. Token situation | 6 points

(1) Basic situation of Token
Token name: COCOS
Total tokens in circulation: 100 billion
Consensus mechanism: DPOS
(2) Token usage and allocation
Part I 82%: Cocos-BCX is used for the platform community construction in various ways, including but not limited to the witness' block reward, incentives for platform ecological developers, global community construction, marketing and promotion, industry alliances, eco-investment, research, financial and legal compliance. The use of this part of Cocos-BCX includes swapping by means of the consensus work contributions, free gifts, gifts in exchange for service, and gifts in exchange for other tokens, etc.
Part II, 18%: Cocos-BCX is intended as incentives for the sponsoring team of the project. The incentive part will set up a locking mechanism, which will be issued and unlocked one-third at the end of each year after Token generation, and the issuance will be completed within three years.

https://preview.redd.it/sahtuohmtb821.jpg?width=684&format=pjpg&auto=webp&s=324cbde0e5911f219649d8a64470dc3d70ecdb7f
u Analysis: The use of Token is mainly divided into two parts, among which, 82% is used for project development and construction. The remaining 18%, which has a locked position mechanism, is intended for team incentive and construction. The use design is rather rational, but the team part is slightly higher. Given that the industry is in the initial stage of development, it is of great importance to seize the first opportunity and acquire early traffic users. It is suggested that the proportion of Token used by the team be reduced slightly, which is more conducive to the long-term development of the project. It should be noted that the original holding distribution of Token has not been queried via the official channel, while this link for the conventional blockchain project are basically disclosed. Meanwhile, from the standpoint of ordinary investors, Token’s original holding ratio is also one of the important parameters for its investment.

2. Ecological cycle | 8 points

(1)The Token (COCOS) positioning of the platform: circulation media and governance proof in eco-economic activities
COCOS not only serves as a value exchange carrier and community participation proof for Cocox-BCX, but its orientation as a basic pricing Token is likely to play a critical role in the digital asset ecosystem. With the continuous development of the industry, a large quantity of decentralized digital assets will exist in multiple blockchain ecosystems according to different standards in the future, and the value existing in asset pricing media transcending the chain ecology will be infinitely magnified.
, which is specifically manifested in that developers and users can evaluate, compare, trade and manage digital assets of different chain ecosystems, worldview content, and technical standards based on COCOS. Meanwhile, as a primary and basic pricing medium, COCOS is positioned to become the necessary conditions for the blockchain industry to develop and trade financial products and derivatives of digital assets in the future.
(2)Basic use model of Token (COCOS)
Ø Value exchange medium within the platform ecosystem;
Ø Entrusted consensus equity share representative of the Cocos-BCX public blockchain;
Ø The reference and basis for the measurement of the participation in and contribution to the platform community.
(3)How to obtain Token (COCOS)
Ø Value creation: It includes the contribution of the behavior of creating digital assets, that is, developing games, making props, etc.
Ø Platform contribution reward: Users who contribute to the Cocos-BCX community is entitled to COCOS;
Ø Market transaction: Selling the prop assets obtained in the game to get COCOS;
Ø Behavioral incentives: Various effective behaviors within the Cocos-BCX platform, community and platform games will be converted into COCOS
according to a certain contribution degree.
u Analysis: The use model, scenario application, acquisition method, market orientation, etc. for the Token ecosystem design are all well deliberated, to be verified by the market.
The ecosystem design of the Token project not only takes the macroscopic use model and scenario application, but also gives a detailed description of the acquisition method. Another point that must be pointed out is that it has a clear market orientation and future prospect as soon as the design begins, therefore, in general the Token ecosystem design is well-considered and far-sighted. However, for the volatile blockchain market, the crux depends on whether the ecological design philosophy can keep pace with the times, which is very essential. In a word, in the face of massive uncertainties, it needs to be finally verified by the market.

(四) Tech Analysis

1. Tech highlights | 9 points

(1) Smart contract system which can be updated iteratively: The smart contract system, represented by Ethereum, is not subject to modification once its definition is published, making it difficult to meet the volatile demands of market. Therefore, an iterative smart contract system is designed to address this pain spot.
(2) Prop circulation platform: Unlike conventional game transaction platform, Cocos-BCX's decentralized digital asset circulation platform does not have intermediary agencies. Players can complete the transfer and purchase of non-homogeneous assets, including "game gold coins" and prop assets acquired in the game on the prop circulation platform. In the whole process of transfer, the platform will adopt smart contract for automatic matching to help users complete the transfer process more efficiently.
(3) Game interactive operation environment:
Based on the judgment of the operation environment characteristics of blockchain games in the future, Cocos-BCX has designed a set of integrated operation environment that accommodates various types of APPs, as well as the supporting interoperability interface. Combined with COCOS Creator, it simplifies the process of docking game programs and blockchain, making intra-chain interaction transparent to developers, and allowing conventional game developers to develop or migrate blockchain game without a threshold.
(4) Mapping gateway that supports multi-chain and asset riveting:
Cocos-BCX provides a set of mapping gateways used for the automatic mapping of game gold coins and props. Under the unified value measurement system, it realizes the smooth transition of different in-chain game content and different platform content. The content that can be used for mapping includes game gold coins, game equipment data, etc.
(5) Transaction authentication mechanism that prevents BP/developers from cheating:
BP, as the core of transaction processing and communication of the whole network, can know the processing result of the latest transaction prior to general nodes. Therefore, BP enjoys a priority for information with timeliness or confidentiality
, as compared with general nodes, so it has a cheating potential in terms of
information acquisition. To address the drawbacks of this technical link, five modular confrontation mechanisms has been specially designed to hold the likelihood of BP/developer cheating at bay.
(6) Economies Principle Design of Cocos-BCX:
The Cocos-BCX platform carries the game assets value created by developers by providing a complete set of functional components including the underlying public blockchain, digital property management, and exchanges. Its technology and governance structure design, based on the graphene standard, has the economic attributes corresponding to the DPoS consensus mechanism.
u Analysis: There are a multiplicity of technical highlights in that the overall technology construction shows characteristics such as rigid logic and prominent modularity, and various technical solutions and mechanisms with a strong pertinence have been put forward.
Based on the market pain spots of the game industry, and combined with the development opportunities of blockchain technology, the Cocos-BCX project puts forward a vision system to create consistence between the content producer and consumer in the digital world. In view of the initial intention of the project and the relatively profound background of the game industry, the overall technical structure design of the project is highly targeted and has a strong logic, which can be described as closely connected with each other. Based on the large technical framework system, each technical link and organization also has a strong sense of target and logical gene, and on this basis, many modular and modified technical programs or mechanisms have been proposed. However, it is worth noting that the synergy of a series of highlight technologies remains to be verified and examined. Meanwhile, attention should also be paid to the practicability and rationality.

2. Impossible Triangle | 7 points

(1) Decentralization
Ø Low fork risk: Cocos-BCX uses the DPoS consensus mechanism, which does not require miners to use mining machines for mining, and thereby it can effectively avoid the impact of centralized computing on the entire basechain, which in turn reduces a low fork risk. Under the DPoS mechanism, if a witness wants to fork by voting, it is necessary to guarantee that over one third of the witnesses violate this mechanism at the same time.
Ø Improved DPOS consensus mechanism: The consensus layer of the Cocos-BCX test chain adopts the DPoS consensus algorithm. The advantage characteristics of the improved edition DPOS are as follows: all active witnesses have the same block predefined probability as the witnesses' predefined algorithm in the DPoS consensus algorithm, which ensures that the block probability of all witnesses is consistent with the block reward.
Ø Lightweight node: In Cocos-BCX design, lightweight node is essentially an environment with chain interoperability. Unlike the whole node, the lightweight node does not require to synchronize the whole network data. Instead, it needs the contract information and environment data required for synchronous running. This design can greatly reduce the data volume and synchronization time required for node synchronization, enabling the in-chain game terminal software to have a capacity which is actually used and a plausible time cost.
(2) Security
Ø Player autonomy and asset security: Because of the open and transparent characteristics of the blockchain network, the digital asset information obtained by players in the game can be viewed through the blockchain.
Ø Guarantee by modern cryptography: Modern cryptography is a technology based on mathematics. Currently, it has been widely used in many industries in the Internet domain. Common symmetric encryption technologies include AES encryption used for WiFi, and asymmetric encryption algorithms (public and private key cryptography) RSA, ECC, etc., among which, ECC (Elliptic Curves Cryptography) is an encryption algorithm commonly used in the blockchain field.
Ø A transaction verification mechanism that prevents BP/developers from cheating: BP enjoys a priority compared with general nodes, so it has the probability to cheat in terms of information acquisition. Therefore, the BCX program has designed a set of transaction execution, messaging, and operating mechanisms to address the possible links that allow cheating by BP and developers.
Ø Iterative updated smart contract system: It can provide logical updating and loophole repair for the in-chain game smart contract, thus ensuring the security and timeliness of the smart contract.
(3) Expandability:
Ø Strong expandability of the top-level design of the project
The expandability of Cocos-BCX is powerful, which is specifically shown in a decentralized game production and an overall solution to the game economy operation established by means of the game engine, development environment and Cocos-BCX game chain.

https://preview.redd.it/xm5n7esrtb821.jpg?width=1207&format=pjpg&auto=webp&s=c3daa5d913560c0e8143c0635374596566bdbfc9
A business ecosystem is constructed based on the above overall solution, with the purpose of connecting the global game ecosystem. The main ecological links include developers, users, creative content, key ecological links and blockchain system, etc.

https://preview.redd.it/h4ssn41ttb821.jpg?width=1276&format=pjpg&auto=webp&s=ca6244d17b9745ce41b5be235f75a39f8a8af051
Ø Expanded design of specific technologies and mechanisms
  1. Multi-platform game integration running environment: This platform is mainly characterized by four features, consistent and perfect chain interoperability interface, downward transparent accepting mode, encapsulated atomic operation and multi-platform compatibility.
  2. Interactive interface of blockchain:
Cocos-BCX provides a chain-interactive development environment so that developers can easily interact with the chain through this set of environment. Meanwhile, its blockchain interactive development environment provides development components compatible with multiple working platforms, including SDK for the Android and iOS system, javascript libraries for front-terminal web applications, and python and PHP libraries for back-terminal applications.
u Analysis: The expandability of the project's "impossible triangle" shows the most prominently, and the decentralized attribute is the weakest, whose security is between the two. However, the project takes the three into consideration in terms of the technical mechanism and program function. Yet, the focus is different.
The project interprets the “impossible triangle” by means of thinking and design that focus on technical aspects and key issues.
The security level first guarantees the assets security and freedom of the ecosystem participants, and meanwhile ensures the rationality and security of the overall framework design, and finally takes its system updating and safe recovery into consideration mainly by means of player autonomy, modern cryptography and transaction verification mechanism that prevents BP/developers from cheating.

3. Development difficulty | 8 points

According to the summary of the project white paper, the blockchain game can be generally divided into four developmental stages.
(1)Using the homogeneous assets for the settlement of the game "gold coins";
(2)Free conversion of the game "gold coins" and props;
(3)In-chain operation of critical rules;
(4)Overall in-chain operation of the game
The game in-chain operation is the final form of the industry. Based on the above summary, Cocos-BCX proposes the future development prospect, mainly represented in seven aspects:
(1)Players having a lightweight full-node environment;
(2)The service stack operating in the blockchain environment;
(3)The game engine as one of the node infrastructures;
(4)Providing a joint development/debugging environment including engine, visual IDE, and chain network interactive interface;
(5)a set of asynchronous consensus tasks between nodes to ensure the trustworthiness of the engine environment. This consensus may be based on the discrimination of feature code of
the engine critical function's target code
(6) The game code (contract) is executed by the secure virtual machine controlled by the engine, and the key numerical calculation of the contract may adopt
the “Trusted Execution Environment” scheme, which is executed independently of the main part of the contract;
(7) The key process of the contract is witnessed by the adjacent or related nodes (like players in a copy).
u Analysis: The project covers a multiplicity of technical characteristics and functional mechanisms. The overall development is rather difficult. However, it is highly practicable in terms of performance.
At the initial stage of the project, four stages of blockchain game development were analyzed. After combing, the highest prospect was proposed, implicating to create a complete multi-platform game running environment, which can provide game developers with convenience in developing blockchain games and a perfect ecological environment to the maximum, while bringing game users a brand-new gaming experience and a game form that transcends the previous ones.
Based on the initial project prospect, numerous technical goals and functional modules are listed, indicating that the technical support for the project vision is rather effective. However, as public blockchain of the industry application basis, it encompasses various technical applications and functional modules. Comparatively speaking, the development difficulty is rather big. Meanwhile, as released by the white paper, the theoretical throughput of the Cocos-BCX test chain can reach up to 100,000 tps. The actual throughput is approximate to 3,500 tps, and the block time is 3 seconds, that is, the information broadcast across the entire network is completed once every 3 seconds. It can be seen from the project technical performance data that it has a relatively strong realistic significance. Therefore, on the whole, the project puts forward a sizeable technical challenge, and in the meantime has a reasonable practicability, therefore, it is worthwhile to look forward to!

u Analysis: The game user and developer group are highly active, and meanwhile the publicity of the media and news client are enhanced. The overall heat and operation and maintenance thinking are well-balanced. However, the current community operation link is relatively weak, and requires improvement in the follow-up.
Presently, the number of community fans is small. Therefore, the operation link of project content is rather weak. However, media communication and news broadcasting, two links of propaganda and promotion efforts, are quite effective, basically realizing a timely and real-time posting of the latest developments of the project. Although the media and news client are widely disseminated, their social interaction is relatively weak. The social platform has its own communication limitations. However, it is highly involved in interaction.

(VIII) Social Response | 7.78

User A | Point: 7.9
Comment: From the perspective of production mode and commercialization, this game is the most sophisticated. So I think this project has a very extensive application scenario, especially for developers and users.
User B | Point: 7.0
Comment: Currently, it seems that the game industry is greatly influenced by macro policies. Tencent's recent performance is a case in point. However, the project orientation is quite good.
User C | Point: 8.0
Comment: The technical advantages of the project are particularly prominent, and it also seizes the development opportunities of the blockchain. However, ultimately it needs to undergo the test of the market.
User D | Point: 9.0
Comment: First of all, COCOS has a large number of developers, solid underlying technology and reliable team work, which is worth looking forward to. Of course, great "undertaking" calls for enormous input, especially in technology. The way is arduous and long. Come on.
User E | Point: 7.0
Comment:
As a game practitioner, I would talk something about Cocos-BCX project: when the concept of blockchain game is put forward for everyone to consider, at this stage, it is no doubt that the dimension (type) of the game is developed from the perspective of "inheritance" and "tracing its very origin". If the Cocos-BCX project can be applied by game developers in terms of "development kit", is easy to learn and use, and allows the mobile game developers to shift to the development of blockchain games without a threshold, then the game dimensions and users can be further expanded. In a word, phenomenal games of blockchain games need the support of Cocos-BCX and the efforts of developers, both of which are indispensable. It is hoped that the team will make great efforts in development and publicity. "Coin friends" may not need to know how the game is developed, but they will certainly care about its future space. Such evaluation can only be called prospects and expectations. It remains to be determined whether the project adopts capital operation or the mode as solid as the old engine of COCOS till the project is landed.

III. Evaluation Summary

The project orientation is accurate, and the team has a strong lineup. It merits pointing out that its technical strength and model architecture design are particularly prominent, and there are an array of investment and cooperation institutions with strong strength. However, at present, the code has not been open sourced and the community operation and maintenance is deficient. The information disclosure of the Token link is not particularly perfect, and individual investors may care much about it. The Roadmap of the project development is all too simple. These are the deficiencies of the project development at the current moment.

II. Project evaluation

(一) Market analysis

1. Market conditions | 8 points

The organizing pattern of productivity dominated by governments in some areas or industrial domains is apt to change in the context of bottlenecks existing for global scientific and technological progress, rising resource consumption, an aging population, and intensified geopolitical conflicts. In particular, in 2008, when Nakamot published his thesis "Bitcoin: A Peer-to-Peer Electronic Cash System", discussions on blockchain and digital currency have gradually extended from technological aspects to economic, social and political, and other fields. The general public have begun to pay close attention to the impact of blockchain on social development as well as the role of digital currency in the world economy. Based on the decentralized characteristics of the blockchain and the vibrant vitality of the digital economy, the general public has enough confidence to predict that the decentralized "digital assets" will be a sweeping trend in the future, and will derive new business models and social values.
At the same time, in the development process of decentralized applications of different types, the game industry enjoys unique development advantages, because the game's production mode is the most sophisticated, enjoys the highest degree in terms of commercialization, and is one of the scenarios with the most profound foundation in terms of developers and users.
u Analysis: The game field has a huge room for development, which is highly consistent with the characteristics of the blockchain, and accords with the future development tendency of the digital economy.
The digital asset economy model carried by the project through the blockchain technology will assetize the content produced by the developer, enable the developer to continue reaping benefits during the use, management and transfer of his assets, and provide him with a convenient, decentralized game distribution channel; meanwhile, it helps players to transform the data formed by time and energy as well as the props they obtain as a result of their consumption into the assets that can be safely stored and circulated, offering players the right to manage and commercialize them.

2. Competition | 8 points

Since the last century till now, owing to the sustained efforts and promotion by a variety of IT technology game enterprises, the national and even global online game market is developing by leaps and bounds. If there is no systematic risks, such as policy regulation, vicious incidents and other factors, there will be no smooth and endless development momentum unless something unexpected happens. However, an objective analysis reveals that the current online game market is still dominated by IT technology companies, and even in a controlled and monopolized development, which, of course, also brings substantial profits, such as Tencent, Blizzard Tech.
u Analysis: It can be predicted that the Cocos-BCX project will hardly have any direct competitors in the strict sense for the time being, but will encounter a marginal pressure competitive environment from two dimensions. In summary, the classical IT game companies at home and abroad are massive in size and have obvious capital advantages. However, the Cocos-BCX project has an advanced philosophy and cutting edge technology, and thereby enjoys first-mover advantages for a breakthrough; The blockchain game project of the same business is currently marked by wide participation and generic applicability. But in comparison, the Cocos-BCX game industry has such advantages as a salient background, special project orientation and sophisticated development in technical modules, and therefore has greater development potential.

(二) Token Status

1. Token situation | 6 points

(1) Basic situation of Token
Token name: COCOS
Total tokens in circulation: 100 billion
Consensus mechanism: DPOS
(2) Token usage and allocation
Part I 82%: Cocos-BCX is used for the platform community construction in various ways, including but not limited to the witness' block reward, incentives for platform ecological developers, global community construction, marketing and promotion, industry alliances, eco-investment, research, financial and legal compliance. The use of this part of Cocos-BCX includes swapping by means of the consensus work contributions, free gifts, gifts in exchange for service, and gifts in exchange for other tokens, etc.
Part II, 18%: Cocos-BCX is intended as incentives for the sponsoring team of the project. The incentive part will set up a locking mechanism, which will be issued and unlocked one-third at the end of each year after Token generation, and the issuance will be completed within three years.

https://preview.redd.it/s47w2jtfj6521.jpg?width=684&format=pjpg&auto=webp&s=a60ea62b86dc0f177f9596608d1961e039d3bd1b
u Analysis: The use of Token is mainly divided into two parts, among which, 82% is used for project development and construction. The remaining 18%, which has a locked position mechanism, is intended for team incentive and construction. The use design is rather rational, but the team part is slightly higher. Given that the industry is in the initial stage of development, it is of great importance to seize the first opportunity and acquire early traffic users. It is suggested that the proportion of Token used by the team be reduced slightly, which is more conducive to the long-term development of the project. It should be noted that the original holding distribution of Token has not been queried via the official channel, while this link for the conventional blockchain project are basically disclosed. Meanwhile, from the standpoint of ordinary investors, Token’s original holding ratio is also one of the important parameters for its investment.

2. Ecological cycle | 8 points

(1)The Token (COCOS) positioning of the platform: circulation media and governance proof in eco-economic activities
COCOS not only serves as a value exchange carrier and community participation proof for Cocox-BCX, but its orientation as a basic pricing Token is likely to play a critical role in the digital asset ecosystem. With the continuous development of the industry, a large quantity of decentralized digital assets will exist in multiple blockchain ecosystems according to different standards in the future, and the value existing in asset pricing media transcending the chain ecology will be infinitely magnified.
, which is specifically manifested in that developers and users can evaluate, compare, trade and manage digital assets of different chain ecosystems, worldview content, and technical standards based on COCOS. Meanwhile, as a primary and basic pricing medium, COCOS is positioned to become the necessary conditions for the blockchain industry to develop and trade financial products and derivatives of digital assets in the future.
(2)Basic use model of Token (COCOS)
Ø Value exchange medium within the platform ecosystem;
Ø Entrusted consensus equity share representative of the Cocos-BCX public blockchain;
Ø The reference and basis for the measurement of the participation in and contribution to the platform community.
(3)How to obtain Token (COCOS)
Ø Value creation: It includes the contribution of the behavior of creating digital assets, that is, developing games, making props, etc.
Ø Platform contribution reward: Users who contribute to the Cocos-BCX community is entitled to COCOS;
Ø Market transaction: Selling the prop assets obtained in the game to get COCOS;
Ø Behavioral incentives: Various effective behaviors within the Cocos-BCX platform, community and platform games will be converted into COCOS
according to a certain contribution degree.
u Analysis: The use model, scenario application, acquisition method, market orientation, etc. for the Token ecosystem design are all well deliberated, to be verified by the market.
The ecosystem design of the Token project not only takes the macroscopic use model and scenario application, but also gives a detailed description of the acquisition method. Another point that must be pointed out is that it has a clear market orientation and future prospect as soon as the design begins, therefore, in general the Token ecosystem design is well-considered and far-sighted. However, for the volatile blockchain market, the crux depends on whether the ecological design philosophy can keep pace with the times, which is very essential. In a word, in the face of massive uncertainties, it needs to be finally verified by the market.

(四) Tech Analysis

1. Tech highlights | 9 points

(1) Smart contract system which can be updated iteratively: The smart contract system, represented by Ethereum, is not subject to modification once its definition is published, making it difficult to meet the volatile demands of market. Therefore, an iterative smart contract system is designed to address this pain spot.
(2) Prop circulation platform: Unlike conventional game transaction platform, Cocos-BCX's decentralized digital asset circulation platform does not have intermediary agencies. Players can complete the transfer and purchase of non-homogeneous assets, including "game gold coins" and prop assets acquired in the game on the prop circulation platform. In the whole process of transfer, the platform will adopt smart contract for automatic matching to help users complete the transfer process more efficiently.
(3) Game interactive operation environment:
Based on the judgment of the operation environment characteristics of blockchain games in the future, Cocos-BCX has designed a set of integrated operation environment that accommodates various types of APPs, as well as the supporting interoperability interface. Combined with COCOS Creator, it simplifies the process of docking game programs and blockchain, making intra-chain interaction transparent to developers, and allowing conventional game developers to develop or migrate blockchain game without a threshold.
(4) Mapping gateway that supports multi-chain and asset riveting:
Cocos-BCX provides a set of mapping gateways used for the automatic mapping of game gold coins and props. Under the unified value measurement system, it realizes the smooth transition of different in-chain game content and different platform content. The content that can be used for mapping includes game gold coins, game equipment data, etc.
(5) Transaction authentication mechanism that prevents BP/developers from cheating:
BP, as the core of transaction processing and communication of the whole network, can know the processing result of the latest transaction prior to general nodes. Therefore, BP enjoys a priority for information with timeliness or confidentiality
, as compared with general nodes, so it has a cheating potential in terms of
information acquisition. To address the drawbacks of this technical link, five modular confrontation mechanisms has been specially designed to hold the likelihood of BP/developer cheating at bay.
(6) Economies Principle Design of Cocos-BCX:
The Cocos-BCX platform carries the game assets value created by developers by providing a complete set of functional components including the underlying public blockchain, digital property management, and exchanges. Its technology and governance structure design, based on the graphene standard, has the economic attributes corresponding to the DPoS consensus mechanism.
u Analysis: There are a multiplicity of technical highlights in that the overall technology construction shows characteristics such as rigid logic and prominent modularity, and various technical solutions and mechanisms with a strong pertinence have been put forward.
Based on the market pain spots of the game industry, and combined with the development opportunities of blockchain technology, the Cocos-BCX project puts forward a vision system to create consistence between the content producer and consumer in the digital world. In view of the initial intention of the project and the relatively profound background of the game industry, the overall technical structure design of the project is highly targeted and has a strong logic, which can be described as closely connected with each other. Based on the large technical framework system, each technical link and organization also has a strong sense of target and logical gene, and on this basis, many modular and modified technical programs or mechanisms have been proposed. However, it is worth noting that the synergy of a series of highlight technologies remains to be verified and examined. Meanwhile, attention should also be paid to the practicability and rationality.

2. Impossible Triangle | 7 points

(1) Decentralization
Ø Low fork risk: Cocos-BCX uses the DPoS consensus mechanism, which does not require miners to use mining machines for mining, and thereby it can effectively avoid the impact of centralized computing on the entire basechain, which in turn reduces a low fork risk. Under the DPoS mechanism, if a witness wants to fork by voting, it is necessary to guarantee that over one third of the witnesses violate this mechanism at the same time.
Ø Improved DPOS consensus mechanism: The consensus layer of the Cocos-BCX test chain adopts the DPoS consensus algorithm. The advantage characteristics of the improved edition DPOS are as follows: all active witnesses have the same block predefined probability as the witnesses' predefined algorithm in the DPoS consensus algorithm, which ensures that the block probability of all witnesses is consistent with the block reward.
Ø Lightweight node: In Cocos-BCX design, lightweight node is essentially an environment with chain interoperability. Unlike the whole node, the lightweight node does not require to synchronize the whole network data. Instead, it needs the contract information and environment data required for synchronous running. This design can greatly reduce the data volume and synchronization time required for node synchronization, enabling the in-chain game terminal software to have a capacity which is actually used and a plausible time cost.
(2) Security
Ø Player autonomy and asset security: Because of the open and transparent characteristics of the blockchain network, the digital asset information obtained by players in the game can be viewed through the blockchain.
Ø Guarantee by modern cryptography: Modern cryptography is a technology based on mathematics. Currently, it has been widely used in many industries in the Internet domain. Common symmetric encryption technologies include AES encryption used for WiFi, and asymmetric encryption algorithms (public and private key cryptography) RSA, ECC, etc., among which, ECC (Elliptic Curves Cryptography) is an encryption algorithm commonly used in the blockchain field.
Ø A transaction verification mechanism that prevents BP/developers from cheating: BP enjoys a priority compared with general nodes, so it has the probability to cheat in terms of information acquisition. Therefore, the BCX program has designed a set of transaction execution, messaging, and operating mechanisms to address the possible links that allow cheating by BP and developers.
Ø Iterative updated smart contract system: It can provide logical updating and loophole repair for the in-chain game smart contract, thus ensuring the security and timeliness of the smart contract.
(3) Expandability:
Ø Strong expandability of the top-level design of the project
The expandability of Cocos-BCX is powerful, which is specifically shown in a decentralized game production and an overall solution to the game economy operation established by means of the game engine, development environment and Cocos-BCX game chain.

https://preview.redd.it/9zqpm1zzj6521.jpg?width=1207&format=pjpg&auto=webp&s=97073eb57409e0904da5c11873cc543c3b9f310b
A business ecosystem is constructed based on the above overall solution, with the purpose of connecting the global game ecosystem. The main ecological links include developers, users, creative content, key ecological links and blockchain system, etc.

https://preview.redd.it/l83i3pk0k6521.jpg?width=1276&format=pjpg&auto=webp&s=df7e694a557af1485c840ed44b9bbfba432b1d86
Ø Expanded design of specific technologies and mechanisms
1) Multi-platform game integration running environment: This platform is mainly characterized by four features, consistent and perfect chain interoperability interface, downward transparent accepting mode, encapsulated atomic operation and multi-platform compatibility.
2) Interactive interface of blockchain:
Cocos-BCX provides a chain-interactive development environment so that developers can easily interact with the chain through this set of environment. Meanwhile, its blockchain interactive development environment provides development components compatible with multiple working platforms, including SDK for the Android and iOS system, javascript libraries for front-terminal web applications, and python and PHP libraries for back-terminal applications.
u Analysis: The expandability of the project's "impossible triangle" shows the most prominently, and the decentralized attribute is the weakest, whose security is between the two. However, the project takes the three into consideration in terms of the technical mechanism and program function. Yet, the focus is different.
The project interprets the “impossible triangle” by means of thinking and design that focus on technical aspects and key issues.
The security level first guarantees the assets security and freedom of the ecosystem participants, and meanwhile ensures the rationality and security of the overall framework design, and finally takes its system updating and safe recovery into consideration mainly by means of player autonomy, modern cryptography and transaction verification mechanism that prevents BP/developers from cheating.

3. Development difficulty | 8 points

According to the summary of the project white paper, the blockchain game can be generally divided into four developmental stages.
(1)Using the homogeneous assets for the settlement of the game "gold coins";
(2)Free conversion of the game "gold coins" and props;
(3)In-chain operation of critical rules;
(4)Overall in-chain operation of the game
The game in-chain operation is the final form of the industry. Based on the above summary, Cocos-BCX proposes the future development prospect, mainly represented in seven aspects:
(1)Players having a lightweight full-node environment;
(2)The service stack operating in the blockchain environment;
(3)The game engine as one of the node infrastructures;
(4)Providing a joint development/debugging environment including engine, visual IDE, and chain network interactive interface;
(5)a set of asynchronous consensus tasks between nodes to ensure the trustworthiness of the engine environment. This consensus may be based on the discrimination of feature code of
the engine critical function's target code
(6) The game code (contract) is executed by the secure virtual machine controlled by the engine, and the key numerical calculation of the contract may adopt
the “Trusted Execution Environment” scheme, which is executed independently of the main part of the contract;
(7) The key process of the contract is witnessed by the adjacent or related nodes (like players in a copy).
u Analysis: The project covers a multiplicity of technical characteristics and functional mechanisms. The overall development is rather difficult. However, it is highly practicable in terms of performance.
At the initial stage of the project, four stages of blockchain game development were analyzed. After combing, the highest prospect was proposed, implicating to create a complete multi-platform game running environment, which can provide game developers with convenience in developing blockchain games and a perfect ecological environment to the maximum, while bringing game users a brand-new gaming experience and a game form that transcends the previous ones.
Based on the initial project prospect, numerous technical goals and functional modules are listed, indicating that the technical support for the project vision is rather effective. However, as public blockchain of the industry application basis, it encompasses various technical applications and functional modules. Comparatively speaking, the development difficulty is rather big. Meanwhile, as released by the white paper, the theoretical throughput of the Cocos-BCX test chain can reach up to 100,000 tps. The actual throughput is approximate to 3,500 tps, and the block time is 3 seconds, that is, the information broadcast across the entire network is completed once every 3 seconds. It can be seen from the project technical performance data that it has a relatively strong realistic significance. Therefore, on the whole, the project puts forward a sizeable technical challenge, and in the meantime has a reasonable practicability, therefore, it is worthwhile to look forward to!

u Analysis: The game user and developer group are highly active, and meanwhile the publicity of the media and news client are enhanced. The overall heat and operation and maintenance thinking are well-balanced. However, the current community operation link is relatively weak, and requires improvement in the follow-up.
Presently, the number of community fans is small. Therefore, the operation link of project content is rather weak. However, media communication and news broadcasting, two links of propaganda and promotion efforts, are quite effective, basically realizing a timely and real-time posting of the latest developments of the project. Although the media and news client are widely disseminated, their social interaction is relatively weak. The social platform has its own communication limitations. However, it is highly involved in interaction.

(VIII) Social Response | 7.78

User A | Point: 7.9
Comment: From the perspective of production mode and commercialization, this game is the most sophisticated. So I think this project has a very extensive application scenario, especially for developers and users.
User B | Point: 7.0
Comment: Currently, it seems that the game industry is greatly influenced by macro policies. Tencent's recent performance is a case in point. However, the project orientation is quite good.
User C | Point: 8.0
Comment: The technical advantages of the project are particularly prominent, and it also seizes the development opportunities of the blockchain. However, ultimately it needs to undergo the test of the market.
User D | Point: 9.0
Comment: First of all, COCOS has a large number of developers, solid underlying technology and reliable team work, which is worth looking forward to. Of course, great "undertaking" calls for enormous input, especially in technology. The way is arduous and long. Come on.
User E | Point: 7.0
Comment:
As a game practitioner, I would talk something about Cocos-BCX project: when the concept of blockchain game is put forward for everyone to consider, at this stage, it is no doubt that the dimension (type) of the game is developed from the perspective of "inheritance" and "tracing its very origin". If the Cocos-BCX project can be applied by game developers in terms of "development kit", is easy to learn and use, and allows the mobile game developers to shift to the development of blockchain games without a threshold, then the game dimensions and users can be further expanded. In a word, phenomenal games of blockchain games need the support of Cocos-BCX and the efforts of developers, both of which are indispensable. It is hoped that the team will make great efforts in development and publicity. "Coin friends" may not need to know how the game is developed, but they will certainly care about its future space. Such evaluation can only be called prospects and expectations. It remains to be determined whether the project adopts capital operation or the mode as solid as the old engine of COCOS till the project is landed.

III. Evaluation Summary

The project orientation is accurate, and the team has a strong lineup. It merits pointing out that its technical strength and model architecture design are particularly prominent, and there are an array of investment and cooperation institutions with strong strength. However, at present, the code has not been open sourced and the community operation and maintenance is deficient. The information disclosure of the Token link is not particularly perfect, and individual investors may care much about it. The Roadmap of the project development is all too simple. These are the deficiencies of the project development at the current moment.

AMA with Wanchain VP Lini

AMA with Wanchain VP Lini
Original article here: https://medium.com/wanchain-foundation/ama-with-wanchain-vp-lini-58ada078b4fe

“What is unique about us is that we have actually put theory into practice.”
— Lini
https://preview.redd.it/n6lo2xcmtn621.png?width=800&format=png&auto=webp&s=281acce4b45eed8acf0c52b201d01cb6f0d13507
https://preview.redd.it/10aj3ointn621.png?width=800&format=png&auto=webp&s=6a187e8a6eb5ac0445ddc73d5b0f9077f12bce39
Wanchain’s Vice President of Business Development, Lini, sat down with blockchain media organization Neutrino for an AMA covering a wide range of topics concerning Wanchain’s development.
The following is an English translation of the original Chinese AMA which was held on December 13th, 2018:
Neutrino: Could you please first share with us a little basic background, what are the basic concepts behind cross chain technology? What are the core problems which are solved with cross-chain? In your opinion, what is the biggest challenge of implementing cross chain to achieve value transfer between different chains?
Lini: Actually, this question is quite big. Let me break it down into three smaller parts:
  1. First, what is the meaning of “cross-chain”?
https://preview.redd.it/cpui6t7qtn621.png?width=720&format=png&auto=webp&s=86bc39d94b0713949c150598e2397a4f9d3ac491
In China, we like to use the word “cross-chain”, the term “interoperability” is used more frequently in foreign countries. Interoperability is also one of the important technologies identified by Vitalik for the development of a future blockchain ecosystem mentioned in the Ethereum white paper. So cross-chain is basically the concept of interoperability between chains.
  1. The core problem solved by cross chain is that of “multi-ledger” synchronous accounting
https://preview.redd.it/603dl86stn621.png?width=720&format=png&auto=webp&s=425b827298ac919f8cf05909037458a173100cc4
In essence, blockchain is a distributed bookkeeping technique, also known as distributed ledger technology. Tokens are the core units of account on each chain, there currently exist many different chains, each with their own token. Of especial importance is the way in which each ledger uses tokens to interact with each other for the purpose of clearing settlements.
  1. The core purpose of the cross-chain technology is as one of the key infrastructures of the future economy based on digital currencies.
https://preview.redd.it/3d61f26utn621.png?width=720&format=png&auto=webp&s=b735482c9734e1d32176e406adce1718be20583e
Cross chain technology is one of the foundational technological infrastructures that is necessary for the large scale application of blockchain technology.
Neutrino: As we all know, there are many different kinds of cross-chain technologies. Please give us a brief introduction to several popular cross-chain technologies on the market, and the characteristics of each of these technologies。
Lini: Before answering this question, it is very important to share two important concepts with our friends: heterogeneity and homogeneity, and centralization and decentralization.
https://preview.redd.it/n6wbs77wtn621.png?width=720&format=png&auto=webp&s=83fcadd09afb214d2aa5a2a6deb6c24d0d4da671
These two points are especially important for understanding various cross-chain technologies, because there are many different technologies and terminologies, and these are some of the foundational concepts needed for understanding them.
There are also two core challenges which must be overcome to implement cross-chain:
https://preview.redd.it/84wqd28ytn621.png?width=720&format=png&auto=webp&s=dafe1cd2993f853547b532421404e6ab86e185f1
Combining the above two points, we look at the exploration of some solutions in the industry and the design concepts of other cross-chain projects.
First I’d like to discuss the Relay solution.
https://preview.redd.it/qgcqiwlztn621.png?width=720&format=png&auto=webp&s=0925d4221c9e92e365e150638c645bef8c609b3f
However the Relay solution must consume a relatively large amount of gas to read the BTC header. Another downside is that, as we all know, Bitcoin’s blocks are relatively slow, so the time to wait for verification will be long, it usually takes about 10 minutes to wait for one block to confirm, and the best practice is to wait for 6 blocks.
The next concept is the idea of Sidechains.
https://preview.redd.it/9cg79bl1un621.png?width=720&format=png&auto=webp&s=1260e14213b1757eadc4b6141a365ed3b0e20316
This solution is good, but not all chains contain SPV, a simple verification method. Therefore, there are certain drawbacks. Of course, this two way peg way solves challenge beta very well, that is, the atomicity of the transaction.
These two technical concepts have already been incorporated into a number of existing cross chain projects. Let’s take a look at two of the most influential of these.
The first is Polkadot.
https://preview.redd.it/1o3xwz93un621.png?width=720&format=png&auto=webp&s=249909a33b5420050a6010b961a944285fc94926
This is just a summary based on Polkadot’s whitepaper and most recent developments. The theoretical design is very good and can solve challenges alpha and beta. Last week, Neutrino organized a meetup with Polkadot, which we attended. In his talk, Gavin’s focus was on governance, he didn’t get into too much technical detail, but Gavin shared some very interesting ideas about chain governance mechanisms! The specific technical details of Polkadot may have to wait until after their main net is online before it can be analyzed.
Next is Cosmos.
https://preview.redd.it/5gtjf6x4un621.png?width=720&format=png&auto=webp&s=94d6408ff65dc7041316f0130867888e108848b2
Cosmos is a star project who’s basic concept is similar to Polkadot. Cosmos’s approach is based on using a central hub. Both projects both take into account the issue of heterogeneous cross-chain transactions, and both have also taken into account how to solve challenges alpha and beta.
To sum up, each research and project team has done a lot of exploration on the best methods for implementing cross-chain technology, but many are still in the theoretical design stage. Unfortunately, since the main net has not launched yet, it is not possible to have a more detailed understanding of each project’s implementation. A blockchain’s development can be divided into two parts: theoretical design, and engineering implementation. Therefore, we can only wait until after the launch of each project’s main network, and then analyze it in more detail.
Neutrino: As mentioned in the white paper, Wanchain is a general ledger based on Ethereum, with the goal of building a distributed digital asset financial infrastructure. There are a few questions related to this. How do you solve Ethereum’s scaling problem? How does it compare with Ripple, which is aiming to be the standard trading protocol that is common to all major banks around the world? As a basic potential fundamental financial infrastructure, what makes Wanchain stand out?
Lini: This question is actually composed of two small questions. Let me answer the first one first.
  1. Considerations about TPS.
First of all, Wanchain is not developed on Ethereum. Instead, it draws on some of Ethereum’s code and excellent smart contracts and virtual machine EVM and other mature technical solutions to build the mainnet of Wanchain.
The TPS of Ethereum is not high at this stage, which is limited by various factors such as the POW consensus mechanism. However, this point also in part is due to the characteristics of Ethereum’s very distributed and decentralized features. Therefore, in order to improve TPS, Wanchain stated in its whitepaper that it will launch its own POS consensus, thus partially solving the performance issues related to TPS. Wanchain’s POS is completely different from the POS mechanism of Ethereum 2.0 Casper.
Of course, at the same time, we are also paying close attention to many good proposals from the Ethereum community, such as sharding, state channels, side chains, and the Raiden network. Since blockchain exists in the world of open source, we can of course learn from other technological breakthroughs and use our own POS to further improve TPS. If we have some time at the end, I’d love to share some points about Wanchain’s POS mechanism.
  1. Concerning, Ripple, it is completely different from what Wanchain hopes to do.
Ripple is focused on exchanges between different fiat pairs, the sharing of data between banks and financial institutions, as a clearing and settlement system, and also for the application of DLT, for example the Notary agent mechanism.
Wanchain is focused on different use cases, it is to act as a bridge between different tokens and tokens, and between assets and tokens. For various cross-chain applications it is necessary to consume WAN as a gas fee to pay out to nodes.
So it seems that the purpose Ripple and Wanchain serve are quite different. Of course, there are notary witnesses in the cross-chain mechanism, that is, everyone must trust the middleman. Ripple mainly serves financial clients, banks, so essentially everyone’s trust is already there.
Neutrino: We see that Wanchain uses a multi-party computing and threshold key sharing scheme for joint anchoring, and achieves “minimum cost” for integration through cross-chain communication protocols without changing the original chain mechanism. What are the technical characteristics of multi-party computing and threshold key sharing? How do other chains access Wanchain, what is the cross-chain communication protocol here? What is the cost of “minimum cost?
Lini: The answer to this question is more technical, involving a lot of cryptography, I will try to explain it in a simple way.
  1. About sMPC -
It stands for secure multi-party computation. I will explain it using an example proposed by the scholar Andrew Yao, the only Turing Award winner in China. The scenario called Yao’s Millionaire Problem. How can two millionaires know who is wealthier without revealing the details of their wealth to each other or a trusted third party? I’m not going to explain the answer in detail here, but those who are interested can do a web search to learn more.
In sMPC multiple parties each holding their own piece of private data jointly perform a calculation (for example, calculating a maximum value) and obtain a calculation result. However, in the process, each party involved does not leak any of their respective data. Essentially sMPC calculation can allow for designing a protocol without relying on any trusted third parties, since no individual ever has access to the complete private information.
Secure multiparty computing can be abstractly understood as two parties who each have their own private data, and can calculate the results of a public function without leaking their private data. When the entire calculation is completed, only the calculation results are revealed to both parties, and neither of them knows the data of the other party and the intermediate data of the calculation process. The protocol used for secure multiparty computing is homomorphic encryption + secret sharing + OT (+ commitment scheme + zero knowledge proofs, etc.)
Wanchain’s 21 cross chain Storeman nodes use sMPC to participate in the verification of a transaction without obtaining of a user’s complete private key. Simply put, the user’s private key will have 21 pieces given to 21 anonymous people who each can only get 1/21 part, and can’t complete the whole key.
  1. Shamir’s secret sharing
There are often plots in a movie where a top secret document needs to be handed over to, let’s say five secret agents. In order to protect against the chance of an agent from being arrested or betraying the rest, the five agents each hold only part of a secret key which will reveal the contents of the documents. But there is also a hidden danger: if one the agents are really caught, how can the rest of the agents access the information in the documents? At this point, you may wonder if there is any way for the agents to still recover the original text with only a portion of the keys? In other words, is there any method that allows a majority of the five people to be present to unlock the top secret documents? In this case, the enemy must be able to manipulate more than half of the agents to know the information in the secret documents.
Wanchain uses the threshold M<=N; N=21; M=16. That is to say, at least 16 Storeman nodes must participate in multi-party calculation to confirm a transaction. Not all 21 Storeman nodes are required to participate. This is a solution to the security problem of managing private keys.
Cross-chain communication protocols refers to the different communication methods used by different chains. This is because heterogeneous cross-chain methods can’t change the mechanism of the original chains. Nakamoto and Vitalik will not modify their main chains because they need BTC and ETH interoperability. Therefore, project teams that can only do cross-chain agreements to create different protocols for each chain to “talk”, or communicate. So the essence of a cross-chain protocol is not a single standard, but a multiple sets of standards. But there is still a shared sMPC and threshold design with the Storeman nodes.
The minimum cost is quite low, as can be shown with Wanchain 3.0’s cross chain implementation. In fact it requires just two smart contracts, one each on Ethereum and Wanchain to connect the two chains. To connect with Bitcoin all that is needed is to write a Bitcoin script. Our implementation guarantees both security and decentralization, while at the same time remaining simple and consuming less computation. The specific Ethereum contract and Bitcoin scripts online can be checked out by anyone interested in learning more.
Neutrino: What kind of consensus mechanism is currently used by Wanchain? In addition, what is the consensus and incentive mechanism for cross-chain transactions, and what is the purpose of doing so? And Wanchain will support cross-chain transactions (such as BTC, ETH) on mainstream public chains, asset cross-chain transactions between the alliance chains, and cross-chain transactions between the public and alliance chains, how can you achieve asset cross-chain security and privacy?
Lini: It is now PPOW (Permissioned Proof of Work), in order to ensure the reliability of the nodes before the cross-chain protocol design is completed, and to prepare to switch to POS (as according to the Whitepaper roadmap). The cross-chain consensus has been mentioned above, with the participation of a small consensus (at least 16 nodes) in a set of 21 Storeman nodes through sMPC and threshold secret sharing.
In addition, the incentive is achieved through two aspects: 1) 100% of the cross chain transaction fee is used to reward the Storeman node; 2) Wanchain has set aside a portion of their total token reserve as an incentive mechanism for encouraging Storeman nodes in case of small cross-chain transaction volume in the beginning.
It can be revealed that Storeman participation is opening gradually and will become completely distributed and decentralized in batches. The first phase of the Storeman node participation and rewards program is to be launched at the end of 2018. It is expected that the selection of participants will be completed within one quarter. Please pay attention to our official announcements this month.
In addition, for public chains, consortium chains, and private chains, asset transfer will also follow the cross-chain mechanism mentioned above, and generally follow the sMPC and threshold integration technology to ensure cross-chain security.
When it comes to privacy, this topic will be bigger. Going back to the Wanchain Whitepaper, we have provided privacy protection on Wanchain mainnet. Simply put, the principle is using ring signatures. The basic idea is that it mixes the original address with many other addresses to ensure privacy. We also use one-time address. In this mechanism a stamp system is used that generates a one-time address from a common address. This has been implemented since our 2.0 release.
But now only the privacy protection of native WAN transactions can be provided. The protection of cross-chain privacy and user experience will also be one of the important tasks for us in 2019.
Neutrino: At present, Wanchain uses Storeman as a cross-chain trading node. Can you introduce the Storeman mechanism and how to protect these nodes?
Lini: Let me one problem from two aspects.
  1. As I introduced before in my explanation of sMPC, the Storeman node never holds the user’s private key, but only calculates the transaction in an anonymous and secure state, and the technology prevents the Storeman nodes from colluding.
  2. Even after technical guarantees, we also designed a “double protection” against the risk from an economic point of view, that is, each node participating as a Storeman needs to pledge WAN in the contract as a “stake”. The pledge of WAN will be greater than the amount of any single transaction as a guarantee against loss of funds.
If the node is malicious (even if it is a probability of one in a billion), the community will be compensated for the loss caused by the malicious node by confiscation of the staked WAN. This is like the POS mechanism used by ETH, using staking to prevent bad behavior is a common principle.
Neutrino: On December 12th, the mainnet of Wanchain 3.0 was launched. Wanchain 3.0 opened cross-chain transactions between Bitcoin, Ethereum and ERC20 (such as MakerDao’s stable currency DAI and MKR). What does this version mean for you and the industry? This upgrade of cross-chain with Bitcoin is the biggest bright spot. So, if now you are able to use Wanchain to make transactions between what is the difference between tokens, then what is the difference between a cross chain platform like Wanchain and cryptocurrency exchanges?
Lini: The release of 3.0 is the industry’s first major network which has crossed ETH and BTC, and it has been very stable so far. As mentioned above, many cross-chain, password-protected theoretical designs are very distinctive, but for engineering implementation, the whether or not it can can be achieved is a big question mark. Therefore, this time Wanchain is the first network launched in the world to achieve this. Users are welcome to test and attack. This also means that Wanchain has connected the two most difficult and most challenging public networks. We are confident we will soon be connecting other well-known public chains.
At the same time of the release of 3.0, we also introduced cross chain integration with other ERC20 tokens in the 2.X version, such as MakerDao’s DAI, MKR, LRC, etc., which also means that more tokens of excellent projects on Ethereum will also gradually be integrated with Wanchain.
Some people will be curious, since Wanchain has crossed so many well-known public chains/projects; how is it different with crypto exchanges? In fact, it is very simple, one centralized; one distributed. Back to the white paper of Nakamoto, is not decentralization the original intention of blockchain? So what Wanchain has to do is essentially to solve the bottom layer of the blockchain, one of the core technical difficulties.
Anyone trying to create a DEX (decentralized exchange); digital lending and other application scenarios can base their application on Wanchain. There is a Wanchain based DEX prototype made by our community members Jeremiah and Harry, which quite amazing. Take a look at this video below.
https://www.youtube.com/watch?v=codcqb66G6Q
Neutrino: What are the specific application use cases after the launch of Wanchain 3.0? Most are still exploring small-scale projects. According to your experience, what are the killer blockchain applications of the future? What problems need to be solved during this period? How many years does it take?
Lini:
  1. Wanchain is just a technology platform rather than positioning itself as an application provider; that is, Wanchain will continue to support the community, and the projects which use cross-chain technology to promote a wide range of use cases for Wanchain.
  2. Cross-chain applications that we anticipate include things like: decentralized exchanges, digital lending, cross chain games, social networking dAPPs, gambling, etc. We also expect to see applications using non fungible tokens, for example exchange of real assets, STOs, etc.
  3. We recently proposed the WanDAPP solution. Simply speaking, a game developer for example has been developing on Ethereum, and ERC20 tokens have been issued, but they hope to expand the player base of their games to attract more people. To participate and make full use of their DAPP, you can consider using the WanDAPP solution to deploy the game DAPP on other common platforms, such as EOS, TRON, etc., but you don’t have to issue new tokens on these chains or use the previous ERC20 tokens. In this way the potential user population of the game can be increased greatly without issuing more tokens on a new chain, improving the real value of the original token. This is accomplished completely using the cross-chain mechanism of Wanchain.
  4. For large-scale applications, the infrastructure of the blockchain is not yet complete, there are issues which must first be dealt with such as TPS, sharding, sidechains, state channels, etc. These all must be solved for the large-scale application of blockchain applications. I don’t dare to guess when it will be completed, it depends on the progress of various different technical projects. In short, industry practitioners and enthusiasts need a little faith and patience.
Neutrino community member Block Venture Capital Spring: Will Wanchain be developing any more cross chain products aimed at general users? For example will the wallet be developed to make automatic cross chain transfers with other public chains? Another issue the community is concerned about is the currency issuance. Currently there are more than 100 million WAN circulating, what about the rest, when will it be released?
Lini: As a cross-chain public chain, we are not biased towards professional developers or ordinary developers, and they are all the same. As mentioned above, we provide a platform as infrastructure, and everyone is free to develop applications on us.
For example, if it is a decentralized exchange, it must be for ordinary users to trade on; if it is some kind of financial derivatives product, it is more likely to be used by finance professionals. As for cross-chain wallets which automatically exchange, I’m not sure if you are talking about distributed exchanges, the wallet will not be “automatic” at first, but you can “automatically” redeem other tokens.
Finally, the remaining WAN tokens are strictly in accordance with the plan laid out in the whitepaper. For example, the POS node reward mentioned above will give 10% of the total amount for reward. At the same time, for the community, there are also rewards for the bounty program. The prototype of the DEX that I just saw is a masterpiece of the overseas community developers, and also received tokens from our incentive program.
Neutrino community member’s question: There are many projects in the market to solve cross-chain problems, such as: Cosmos, Polkadot, what are Wanchain’s advantages and innovations relative to these projects?
Lini: As I mentioned earlier, Cosmos and pPolkadot all proposed very good solutions in theory. Compared with Wanchain, I don’t think that we have created anything particularly unique in our theory. The theoretical basis for our work is cryptography, which is derived from the academic foundation of scholars such as Yao Zhizhi and Silvio Micali. Our main strong point is that we have taken theory and put it into practice..
Actually, the reason why people often question whether a blockchain project can be realized or not is because the whitepapers are often too ambitious. Then when they actually start developing there are constant delays and setbacks. So for us, we focus on completing our very solid and realizable engineering goals. As for other projects, we hope to continue to learn from each other in this space.
Neutrino community member Amos from Huobi Research Institute question: How did you come to decide on 21 storeman nodes?
Lini: As for the nodes we won’t make choices based on quantity alone. The S in the POS actually also includes the time the tokens are staked, so that even if a user is staking less tokens, the amount of time they stake them for will also be used to calculate the award, so that is more fair. We designed the ULS (Unique Leader Selection) algorithm in order to reduce the reliance on the assumption of corruption delay (Cardano’s POS theory). which is used for ensuring fairness to ensure that all participants in the system can have a share of the reward, not only few large token holders.
Wu Di, a member of the Neutrino community: Many big exchanges have already begun to deploy decentralized exchanges. For example, Binance, and it seems that the progress is very fast. Will we be working with these influential exchanges in the future? We we have the opportunity to cooperate with them and broaden our own influence?
Lini: I also have seen some other exchange’s DEX. Going back the original point, distributed cross-chain nodes and centralized ones are completely different. I’m guessing that most exchanges use a centralized cross-chain solution, so it may not be the same as the 21 member Storeman group of Wanchain, but I think that most exchanges will likely be using their own token and exchange system. This is my personal understanding. But then, if you are developing cross chain technology, you will cooperate with many exchanges that want to do a DEX. Not only Binance, but also Huobi, Bithumb, Coinbase… And if there is anyone else who would like to cooperate we welcome them!
Neutrino community member AnneJiang from Maker: Dai as the first stable chain of Wanchain will open a direct trading channel between Dai and BTC. In relation to the Dai integration, has any new progress has been made on Wanchain so far?
Lini: DAI’s stable currency has already been integrated on Wanchain. I just saw it yesterday, let me give you a picture. It’s on the current 3.0 browser, https://www.wanscan.org/, you can take a look at it yourself.
This means that users with DAI are now free to trade for BTC, or ETH or some erc20 tokens. There is also a link to the Chainlink, and LRC is Loopring, so basically there are quite a few excellent project tokens. You may use the Wanchain to trade yourself, but since the DEX is not currently open, currently you can only trade with friends you know.
