The protocol not only needethereum etf stock canadas to access data off-chain, but also data on-chain.
Shackle two, the interoperability between traditional games is very limited. To a large extent, many games on the ccardano ada investmenturrent market are still walled gardens: they are independent of different "game worlds" and have their own items and experiences. Of course, this problem is not surprising! Game developers want to gain complete independent control over their own creative efforts, but what if game developers can collaborate with each other in more complex ways?Shackle three, traditional games lack business model options. At this stage, more than 80% of total digital game revenue comes from free games (or "freemium games"). In some successful paid games, most of them only get income through the purchase of skins, which will also limit the design space of some developers. Form follows function. As more game developers launch new business models (such as secondary NFT sales commissions), new game forms will also appear.
Why the "Playing and Earning" game can get a big explosionIn fact, there are five major trends that have driven the explosion of "play while earning" games:Trend 1: The blockchain network continues to expand. Remember the network congestion caused by the "crypto cat" CryptoKitties game in 2017? But now, with the emergence of the second-tier Ethereum expansion protocol, a new high-throughput blockchain, and other scalability solutions, there has been a solid foundation for the vigorous development of blockchain native games;Trend 2: NFT becomes mainstream. Many innovations, including the ERC-721 standard, have spawned the recent upsurge in NFT applications. Game companies now have the tools to NFT games, and more importantly, the public can better understand why rare game assets are valuable.Trend 3: DeFi tools and architectures are increasing. Many basic decentralized financial industry tools (for example, AMM automatic market makers) have been tested in actual combat and have been widely implemented. Game developers can combine these tools to realize game financialization and promote purchase, lending, mortgage and other basic financial activities Now they can all enter the game field smoothly.
Trend 4: Web2 interoperability. Many traditional large-scale technology giants have also begun to join the decentralized ecosystem, and have also opened up a new distribution mechanism for encryption-driven games. For example, Apple’s recent changes to the App Store can make it easier for iOS users to directly access NFT-based “sides”. Play and earn” game.Trend 5: Metaverse. "Meta universe" has become a new frontier of digital experience, and the rapid rise of this emerging concept has even aroused Facebook's interest.Rook is the other half of the Fund of Funds Queen's sub-funds (type B sub-funds, high-risk funds). Holding Rook is equivalent to depositing BTCB on the platform, and using the deposited BTCB as a margin, borrowing from Bishop holders and continuing to purchase Enter the Queen of Funds of Funds and pay a certain amount of interest to Bishop holders.
CHESS is its native token, with a total of 300 million issued. It is currently issued in BSC, but it follows the Erc-20 standard and is widely used for voting and incentives in the Tranchess ecology. CHESS holders will currently share 50% of the agreement fee income, and will vote to determine the internal interest margin imposed on ROOK holders. The team plans to put products on more blockchains in the future and add different types of underlying assets.20% of the token supply will be allocated to the core team;5% of tokens will be provided to seed investors;15% will be reserved for future investors to use in subsequent rounds of financing;
50% of the tokens will be allocated to liquidity mining;10% of the token supply is reserved for the Tranchess ecosystem/treasury-including but not limited to partnerships, third-party services, listing fees.
The purpose of CHESS is to slowly reduce circulation within 4 years. 50% of the community rewards will be distributed on Pancake and TranchesApp.Of the 150 million tokens allocated for community incentives, 120 million are being distributed on the Tranchess app. The liquidity mining activity will continue until November 11, 2021. CHESS will be distributed to QUEEN, BISHOP and ROOK holders in a fixed ratio of 3:4:2.In terms of products, it aims to track more underlying encrypted assets, add various fund structures through innovative synthetic derivatives, and achieve more use cases for its governance token CHESS. Tranchess is looking to expand to multiple chains and build a mature technology and marketing team to cooperate with other agreements in the ecosystem. The project plans to establish a community DAO by the end of this year to take over the governance of the agreement.In July, Tranchess Protocol completed a $1.5 million seed round of funding, led by Arrows Capital and Spartan Group, with participation from Binance Labs, Longhash Ventures, and IMO Ventures. The funds will be used to expand the product to a multi-chain system and transition to the DAO structure before the end of the year.
Tranchess is a team of blockchain and financial experts who have different backgrounds and experiences around the world, covering the U.S., Europe and Asian time zones. Most of the members of the Tranchess team come from investment banks, asset management companies and hedge funds, and have extensive experience in network security for exchanges and DeFi protocols.Its co-founder is Danny Chong. Danny Chong has more than 16 years of banking experience. He was responsible for Crédit Agricole CIB's foreign exchange and fixed-rate product (FX & Rates) sales SEA department.On September 1, the public beta version of Arbitrum, the general expansion network of Ethereum, was officially launched. At the beginning of the launch, it was sought after by many DeFi blue chip applications such as Uniswap, Sushiswap, and Curve. In less than two weeks, the amount of funds locked up reached 2.2 billion. The US dollar has surpassed the public chains of Fantom, Heco, Near, etc., and is close to the current two-tier leader polygon.The launch of Arbitrum has become a milestone in the history of Layer 2 development, and it has been praised by many as "finally there is a "true second layer"." The second layer network, or Layer 2 as we often say, generally refers to the second layer of Ethereum. Their operating logic is simply: to reduce the data processing on the main chain by performing calculations or storage outside the main chain , So as to achieve the purpose of expanding performance, but still relying on the status of the main chain security.
In fact, in the early days of Bitcoin, Layer 2 was already a topic that attracted much attention. At that time, Layer 2 was mainly used to solve the payment expansion of Bitcoin. It proposed a side chain solution including state channels and Liquid, RSK, etc. plan.After entering the era of Ethereum, in addition to the sidechain and state channel solutions that have already appeared, a new expansion plan appeared-Plasma, which was the protagonist of the early Ethereum expansion plan, but later, due to the Plasma plan Security issues, as well as the emergence of the Rollup solution and the maturity of the zero-knowledge proof technology, the Plasma solution was gradually abandoned, and the research direction turned to the current mainstream Rollup solution.
The so-called Rollup here refers to the collection of multiple transactions under the chain, compressed into a transaction, and then sent to the main network, so as to achieve the effect of saving transaction costs and reducing the amount of interaction. How to ensure the security and authenticity of the data under the Rollup chain, based on the different proof mechanisms, gave birth to two mainstream expansion solutions that we are familiar with-ZK Rollp (zero-knowledge proof) and Optimistic Rollup (fraud proof). Each has its own advantages and disadvantages in performance. As we will introduce later, the Arbitrum launched this time is the latter (subtle differences).Because the era of Ethereum sharding is in the foreseeable future, Layer 2 has always been regarded as the best solution to relay the Ethereum ecology. "The current L2 is approximately equivalent to the state of July to August last year." This is Shenyu's current Layer 2 Judgement of the track.
At present, Layer 2 is divided from the width of the application. It can be divided into two categories, general-purpose and vertical. For example, Loopring, dYdX, Synthetix are all vertical applications, and general-purpose ones include Arbitrum, zkSync, etc. It is equivalent to the "Layer 2 public chain". If there is a Layer 2 overlord in the future, then there is a high probability that it will also come out of this field.As a track that has just begun to rise, Layer 2 has high hopes from many people. Some people think that it will start a new round of "DeFi Summer", and some people think that it will give birth to a Layer 2 comparable to Ethereum. So who has it? This potential? What are the Layer 2 general-purpose projects worthy of our attention?At present, the zkSync network only supports the transfer function, and the supported currencies are relatively limited. It only supports dozens of mainstream currencies such as UNI, DAI, USDC, etc. As the ZK Rollup solution has relatively large technical difficulties in compatible EVM, it must be implemented Like Arbitrum's current features, it is not yet realistic. At the end of last month, the official also postponed the launch of the testnet zkSync2.0 (EVM version) and gradually opened the testnet in three phases, precisely for this reason.The interesting point is: in zkSync network payment gas, you can use other tokens instead, you don’t need to have ETH, for example: in Gitcoin donation, if you donate with DAI in zkSync network, you can directly use DAI as Gas fee, for those tokens that do not have a liquid market price, the fee can also be paid with other tokens.In the zkSync network, transaction costs are mainly divided into two parts: the off-chain part and the on-chain part. The off-chain part is the calculation cost of state storage and zero-knowledge proof generation, which is fixed, and the official estimate is about 0.001 US dollars per transfer. The on-chain part is that the verifier must pay Ethereum gas to verify the zero-knowledge proof. The cost is mainly based on the gas price of the Ethereum main network, but this is several orders of magnitude cheaper than the normal ETH/ERC20 transfer cost.Proof mechanism: zero-knowledge proof
Advantages of zkSync: Every transaction data is stored on the main chain, which is more secure; it is faster to exit the second-tier network (ideally a few minutes, but the actual measurement takes about 2-3 hours).zkSync challenges: generating zero-knowledge proofs requires a lot of computing resources, and the hardware threshold for zkSync verifiers is relatively high; it is difficult to implement general smart contract functions (this is a problem that all adopters of ZK Rollup solutions currently face).
Optimism EthereumOptimism Ethereum uses the Optimistic Rollup expansion plan. On January 15 this year, the Optimism team started the trial operation of the mainnet.
The Optimism team hopes to establish instant transactions and scalable smart contracts on Ethereum. The team has created an EVM-compatible solution OVM on Layer 2. Optimism is a scaling solution with a complete cross-layer migration function.At present, only projects that apply for the whitelist can be deployed on the Optimistic Ethereum mainnet. There are not many projects that have been built on Optimism, mainly including cross-chain bridge Optimism Gateway, Hop.Exchange, Celer bridge; DEX platforms uniswap, Kwenta, Rubicon, 1 inch; and 13 applications including option trading platform Lyra and Synthtix.
Projects that have been built in OptimismThe official said before that "the conditions for completely removing the whitelist are not yet available, and a major upgrade is planned in the next three months." On September 13th, Optimism announced that it would double the throughput limit of the main network to handle up to 200,000 transactions per day.When using the Optimism network, the following two points are completely different from Ethereum. You must be clear:First: The transaction is processed according to the first-in-first-out principle, so increasing the gas price will not affect the execution speed of the transaction.
Second: Currently, Optimism uses gas limit to encode information about transactions executed on L2 and on L1 post transaction cost information, so do not try to modify the gas limit automatically provided by the application, otherwise your transaction may be rejected.Proof mechanism: fraud proof
Optimism advantage: Data is stored on the main chain, and it is easier to support general smart contract technology.Optimism challenge: The exit period of the second layer is long (7 days). This is also a problem faced by all Layer 2 solutions that use fraud proof mechanisms. The overall security is slightly lower than that of the main chain and ZK solutions.
Arbitrum was originally an academic project at Princeton University, established by the team Offchain Labs.Arbitrum's proof mechanism is similar to Optimism above. The difference is mainly reflected in the difference in the data uploaded to the main chain. In the process of processing, when someone thinks that the second-level data is in dispute, they can pay a deposit and submit a proof. At this time, the contract will arbitrate it. In the Optimistic Rollup scheme, a complete contract will be simulated and executed on the main chain. Calling consumes high costs; in the Arbitrum Rollup scheme, firstly, through multiple rounds of interactions at the second layer, the dispute scope is reduced before being simulated on the main chain, the number of interactions is reduced, and the cost of dispute resolution on the chain is reduced. This is the biggest difference between the two schemes.
In May of this year, Arbitrum was opened to developers for the first time. On September 1st, the public beta was launched, and the whitelist mechanism was also offline. Similar to Optimism, Arbitrum currently has a clear limit on the upper limit of network processing capacity (80,000 arbgas/s), which roughly matches the current capacity of Ethereum L1, but Arbitrum also stated that as the system becomes stable, the speed limit will be gradually increased in the future. , And continue to improve performance.It is also this limitation. At present, the gas fee of Arbitrum is not very low, which is criticized by everyone, especially when a large number of transactions are influx and reach the upper limit of network capacity, then the cost of L2 will rise further, but compared to the main chain That said, the cost can still be reduced by dozens of times.Comparison of handling fees for Layer 2 transfer of ETH Data source: l2feesIt is undeniable that Arbitrum has fired the first shot of Layer 2 ecological development, but at present, Arbitrum is flooded with too many native dog projects, and everyone must pay attention to risks.
Proof mechanism: fraud proofArbitrum advantages: Data is stored on the main chain, and it is easier to be compatible with EVM; the traditional Optimistic Rollup solution is optimized, which can further reduce costs.
Arbitrum challenge: The exit period of the second layer is longer (7 days), and the overall security is slightly lower than that of the main chain and ZK solutions.StarkNet is a Layer 2 expansion general platform led by StarkWare. It is similar in type to the zkSync we mentioned above, and the difference is mainly reflected in two different zero-knowledge proofs.
zkSync uses zk-SNARKs; StarkNet uses zk-STARKs. For space reasons, the details of the two technologies will not be discussed. We only need to know the final difference: zk-SNARKs on-chain storage space and gas consumption Both are smaller, but zk-STARKs are better in terms of safety.In January of this year, StarkWare announced the roadmap for the development of StarkNet. The team will complete the final Layer 2 ecological deployment (planet, constellation, and universe) in three stages, gradually transition from single-application Rollups to multi-application Rollups, and finally realize the entire governance DAOization.
