Staking in Ethereum 2.0: when will it appear and how much can you earn on it?
Why coin staking will be added in Ethereum 2.0A brief educational program for those who do not follow the update of the project of Vitalik Buterin. Ethereum has long been in need of updating, and the main problem of the network is scalability: the blockchain is overloaded, transactions are slowing down, and the cost of “gas” (transaction fees) is growing. If you do not update the consensus algorithm, then the network will someday cease to be operational. To avoid this, developers have been working for several years on moving the network from the PoW algorithm to state 2.0, running on PoS. This should make the network more scalable, faster and cheaper. In December last year, the first upgrade phase, Istanbul, was implemented in the network, and in April of this year, the Topaz test network with the possibility of staking was launched - the first users already earned 1%. In the PoS algorithm that Ethereum switches to, there is no mining, and validation occurs due to the delegation of user network coins to the masternodes. For the duration of the delegation, these coins are frozen, and for providing their funds for block validation, users receive a portion of the reward. This is staking - such a crypto-analogue of a bank deposit. There are several types of staking: with income from dividends or masternodes, but not the device’s power, as in PoW algorithms, but the number of miner coins is important in all of them. The more coins, the higher the income. For crypto investors, staking is an opportunity to receive passive income from blocked coins. It is assumed that the launch of staking:
The first payments to stakeholders will be one to two years after the launch of the updateThe minimum validator steak will be 32 ETN (≈$6092 for today). This is the minimum number of coins that an ETH holder must freeze in order to qualify for payments. Another prerequisite is not to disconnect your wallet from the network. If the user disconnects and goes into automatic mode, he loses his daily income. If at some point the steak drops below 16 ETH, the user will be deprived of the right to be a validator. The Ethereum network has to go through many more important stages before coin holders can make money on its storage. Collin Myers, the leader of the product strategy at the startup of the Ethereum developer ConsenSys, said that the genesis block of the new network will not be mined until the total amount of frozen funds reaches 524,000 ETN ($99.76 million at the time of publication). So many coins should be kept by 16,375 validators with a minimum deposit of 32 ETN. Until this moment, none of them will receive a percentage profit. Myers noted that this event is not tied to a clear time and depends on the activity of the community. All validators will have to freeze a rather significant amount for an indefinite period in the new network without confidence in the growth of the coin rate. It’s hard to say how many people there are. The developers believe that it will take 12−18 or even 24 months. According to the latest ConsenSys Codefi report, more than 65% of the 300 ETH owners surveyed plan to use the staking opportunity. This sample, of course, is not representative, but it can be assumed that most major coin holders will still be willing to take a chance.
How much can you earn on Ethereum stakingDevelopers have been arguing for a long time about what profitability should be among the validators of the Ethereum 2.0 network. The economic model of the network maintains an inflation rate below 1% and dynamically adjusts the reward scale for validators. The difficulty is not to overpay, but not to pay too little. Profitability will be variable, as it depends on the number and size of steaks, as well as other parameters. The fewer frozen coins and validators, the higher the yield, and vice versa. This is an easy way to motivate users to freeze ETN. According to the October calculations of Collin Myers, after the launch of Ethereum 2.0, validators will be able to receive from 4.6% to 10.3% per annum as a reward for their steak. At the summit, he clarified that the first time after the launch of the Genesis block, it can even reach 20.3%. But as the number of steaks grows, profitability will decline. So, with five million steaks, it drops to about 6.6%. The above numbers are not net returns. They do not include equipment and electricity costs. According to Myers, after the Genesis block, the costs of maintaining the validator node will be about 4.75% of the remuneration. They will continue to increase as the number of blocked coins increases, and with a five millionth steak, they will grow to about 14.7%. Myers emphasized that profitability will be higher for those who will work on their own equipment, rather than relying on cloud services. The latter, according to his calculations, at current prices can bring a loss of up to minus 15% per year. This, he believes, promotes true decentralization. At the end of April, Vitalik Buterin said that validators will be able to earn 5% per annum with a minimum stake of 32 ETH - 1.6 ETH per year, or $ 304 at the time of publication. However, given the cost of freezing funds, the real return will be at 0.8%.
How to calculate profitability from ETN stakingThe easiest way to calculate the estimated return for Ethereum staking is to use a special calculator. For example, from the online services EthereumPrice or Stakingrewards. The service takes into account the latest indicators of network profitability, as well as additional characteristics: the time of operation of a node in the network, the price of a coin, the share of blocked ETNs and so on. Depending on these values, the profit of the validator can vary greatly. For example, you block 32 ETNs at today's coin price - $190, 1% of the coins are blocked, and the node works 99% of the time. According to the EthereumPrice calculator, in this case your yield will be 14.25% per annum, or 4.56 ETH.
Validator earnings from the example above for 10 years according to EthereumPrice.
If to change the data, you have the same steak, but the proportion of blocked coins is 10%. Now your annual yield is only 4.51%, or 1.44 ETH.
Validator earnings from the second example over 10 years according to EthereumPrice.
It is important that this is profitability excluding expenses. Real returns will be significantly lower and in the second case may be negative. In addition, you must consider the fluctuation of the course. Even with a yield of 14% per annum in ETN, dollar-denominated returns may be negative in a bear market.
When will the transition to Ethereum 2.0 startBen Edgington from Teku, the operator of Ethereum 2.0, at the last summit said that the transition to PoS could be launched in July this year. These deadlines, if there are no new delays, were also mentioned by experts of the BitMEX crypto exchange in their recent report on the transition of the Ethereum ecosystem to stage 2.0. However, on May 12, Vitalik Buterin denied the possibility of launching Ethereum 2.0 in July. The network is not yet ready and is unlikely to be launched before the end of the year. July 30 marks the 5th anniversary of the launch of Ethereum. Unfortunately, it seems that it will not be possible to start the update for the anniversary again. Full deployment of updates will consist of several stages. Phase 0. Beacon chain. The "zero" phase, which can be launched in July this year. In fact, it will only be a network test and PoS testing without economic activity, but it will use new ETN coins and the possibility of staking will appear. The "zero" phase will test the first layer of Ethereum 2.0 architecture - Lighthouse. This is the Ethereum 2.0 client in Rust, developed back in 2018. Phase 1. Sharding - rejection of full nodes in favor of load balancing between all network nodes (shards). This should increase network bandwidth and solve the scalability problem. This is the first full phase of Ethereum 2.0. It will initially be deployed with 64 shards. It is because of sharding that the transition of a network to a new state is so complicated - existing smart contracts cannot be transferred to a new network. Therefore, at first, perhaps several years, both networks will exist simultaneously. Phase 2. State execution. In this phase, various applications will work, and it will be possible to conclude smart contracts. This is a full-fledged working Ethereum 2.0 network. After the second phase, two networks will work in parallel - Ethereum and Ethereum 2.0. Coin holders will be able to transfer ETN from the first to the second without the ability to transfer them back. To stimulate network support, coin emissions in both networks will increase until they merge. Read more about the phases of transition to state 2.0 in the aforementioned BitMEX report.
How the upgrade to Ethereum 2.0 will affect the staking market and coin priceThe transition of the second largest coin to PoS will dramatically increase the stake in the market. The deposit in 32 ETH is too large for most users. Therefore, we should expect an increase in offers for staking from the exchanges. So, the launch of such a service in November was announced by the largest Swiss crypto exchange Bitcoin Suisse. She will not have a minimum deposit, and the commission will be 15%. According to October estimates by Binance Research analysts, the transition of Ethereum to stage 2.0 can double the price of a coin and the stake of staking in the market, and it will also make ETH the most popular currency on the PoS algorithm. Adam Cochran, partner at MetaCartel Ventures DAO and developer of DuckDuckGo, argued in his blog that Ethereum's transition to state 2.0 would be the “biggest event” of the cryptocurrency market. He believes that a 3–5% return will attract the capital of large investors, and fear of lost profit (FOMO) among retail investors will push them to actively buy coins. The planned coin burning mechanism for each transaction will reduce the potential oversupply. However, BitMEX experts in the report mentioned above believe that updating the network will not be as important an event as it seems to many, and will not have a significant impact on the coin rate and the staking market. Initially, this will be more likely to test the PoS system, rather than a full-fledged network. There will be no economic activity and smart contracts, and interest for a steak will not be paid immediately. Therefore, most of the economic activity will continue to be concluded in the original Ethereum network, which will work in parallel with the new one. Analysts of the exchange emphasized that due to the addition of staking, the first time (short, in their opinion) a large number of ETNs will be blocked on the network. Most likely, this will limit the supply of coins and lead to higher prices. However, this can also release some of the ETNs blocked in smart contracts, and then the price will not rise. Moreover, the authors of the document are not sure that the demand for coins will be long-term and stable. For this to happen, PoS and sharding must prove that they work stably and provide the benefits for which the update was started. But, if this happens, the network is waiting for a wave of coins from the developers of smart contracts and DeFi protocols. In any case, quick changes should not be expected. A full transition to Ethereum 2.0 will take years and won’t be smooth - network failures are inevitable. We also believe that we should not rely on Ethereum staking as another panacea for all the problems of the coin and the market. Most likely, the transition of the network to PoS will not have a significant impact on the staking market, but may positively affect the price of the coin. However, relying on the ETN rally in anticipation of this is too optimistic.

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.

(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.
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.
