“What is unique about us is that we have actually put theory into practice.”https://preview.redd.it/n6lo2xcmtn621.png?width=800&format=png&auto=webp&s=281acce4b45eed8acf0c52b201d01cb6f0d13507
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:
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.
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.
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.
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:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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: 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.

II. Project evaluation
(一) Market analysis
1. Market conditions | 8 pointsThe 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 pointsSince 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.
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.

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.
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.
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.
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.
Ø Expanded design of specific technologies and mechanisms
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 pointsAccording 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!

(六) Institution enabling (Investors)
1. Cooperative institutions | 9 points
u Analysis: Cocos-BCX has a wide margin for cooperation, and its cooperation institutions are not only numerous, but also mainly of leading and quality enterprises in the industry.
The cooperative institutions include HelloEOS, NEO, NEBULAS (chain), Loom, IMEOS.ONE, Kingsoft Cloud and SlowMist Technology, etc.
NEO is one of the earliest blockchain projects in China. It was officially created in 2014 and was open sourced in real time in Github in June 2015. Since its establishment, the NEO team has experienced ups and downs of the blockchain industry. This project can be said to be a veteran project in the industry. NEO combines with a series of technologies, such as point-to-point network, Byzantine fault tolerance, digital certificate, smart contract, superconducting transactions, and cross-chain interoperability protocols, to perform rapid, efficient, secure, and legitimate smart management of assets.
2. Investment institutions | 9 points
u Analysis: There are numerous investment institutions, many of which are Class I institutions, with a strong institutional strength.
Investment institutions include NGC, Binance, INB Capital, Dfund, 500 Startups, BlockVC, OK Blockchain Capital, Yisu Capital, Xiong'an Capital, ONTology, FreeS FUND, NODE Capital, Consensus Capital, Hash Capital, NEO Capital, Ticker Capital , ContractVC, Junwu Capital, Candy Capital, Hofan VC, BMETA Capital, BYTE Capital, Nimble Capital, InsurFun, BA Capital, Consensus Lab, TOKENMANIA, Byzantium Capital, etc.
The rest investment institutions are also well-known. For example, DFUND was founded by Zhao Dong, a well-known figure in the digital currency domain in July 2017. Yisu Capital is engaged in the early investment and project cooperation, focusing on blockchain technology and big data intelligence analysis, and other domains.
(七) Drawing attention | 6 points
Project content description
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 | 7.78User 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
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 SummaryThe 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.
