Plasma essentially belongs to the category of side chains. First, create a smart contract on Ethereum as a connection between the Ethereum main network and plasma sub-chain. This plasma sub-chain can even be a private chain, and data calculation and processing are both In the plasma sub-chain, the executors of layer 2 only need to periodically submit a "state commitment" to the main chain to ensure the credibility of the data off the chain. The security of this scheme is relatively low, so it is basically used by many mainstream research institutions. Abandoned.For example, the OMG Foundation, which previously focused on plasma, also proposed a new expansion research plan this year-Boba network, and what Boba uses is Optimistic in the Rollup plan.In view of the awkward position of Polygon, many people regard the current Polygon as a pseudo two-layer, but Polygon positions itself as a Layer 2 solution aggregator, which to a certain extent has found another development path for Polygon. Moreover, Polygon has also acquired the ZK Rollup expansion network Hermez launched by iden3, which reduces the doubts about the pseudo-second layer to a certain extent.Proof mechanism: fraud proofPolygon advantage: extremely high scalability, EVM is easily compatible.

Polygon Challenge: Security is the lowest among the above-mentioned schemes.Overall, Optimistic Rollup is the easiest solution to implement under the current technical background, but its essence still does not fundamentally solve the security problem of assets. The ZK Rollup solution may become the final Layer 2 solution, but how to catch up The first-mover advantage of Optimistic Rollup ecological development is also a problem in the ZK Rollup solution.It 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.

StarkNet roadmap plans to complete the aggregation of multiple applications before the end of the yearBut currently, StarkNet is still in the testing phase. On September 1, StarkNet released the Alpha 2 test version, which supports the interaction between smart contracts for the first time. It is reported that the team is currently preparing for the release of the StarkNet Alpha mainnet, which will be approved by then Online application in the form of whitelist.In fact, in addition to the StarkNet mentioned above, Starkware has also proposed another expansion solution, StarkEx (Validium). Currently, there are not many applications that use the StarkEx solution. They are the following four: DeversiFi, dYdX, ImmutableX and Sorare.Although StarkEx also belongs to ZK Rollup, not all data is uploaded to the main chain at the first level. Therefore, theoretically, it can have higher scalability and processing speed. It is precisely for this reason that compared to other Rollup solutions, StarkEx network Data availability and security risks are higher.

Proof mechanism: zero-knowledge proofStarkNet advantage: Data is stored on the main chain, which is more secure than other ZK expansion solutions.StarkNet Challenge: EVM compatible technology is more difficult, and the gas fee is slightly higher than zkSync.Polygon used to be called Matic Network, and the technology used in its L2 chain is plasma.

Polygon advantage: extremely high scalability, EVM is easily compatible.Polygon Challenge: Security is the lowest among the above-mentioned schemes.Overall, Optimistic Rollup is the easiest solution to implement under the current technical background, but its essence still does not fundamentally solve the security problem of assets. The ZK Rollup solution may become the final Layer 2 solution, but how to catch up The first-mover advantage of Optimistic Rollup ecological development is also a problem in the ZK Rollup solution.Looking at all the different Layer 2 general solutions, we found that the current Layer 2 does not have a perfect solution. Different solutions have made a trade-off between safety and efficiency, either the former or the latter, but the most The bottom layer and the core effective solution can only be implemented on layer1, which is also the importance of Eth2 sharding.In the trading market, there is a faintly visible grass snake gray line behind every rise and fall. The cryptocurrency market is no exception.According to data from Coingecko, on September 18, 2021, the price of MX on the Matcha Exchange (MEXC) platform rose 28% from yesterday, reaching a maximum of 1.93 USDT. This is the second time that MX has recorded an intraday increase of more than 20% since the 15th.

This is all related to a rumor circulating in the community.Matcha was acquired by Bybit?

On September 15, there was a rumor that "Matcha was acquired by Bybit" from the community, and the price of MX quickly rose from 1.3 SUDT to 1.6 USDT.On September 16th, in response to the rumors of matcha being acquired, the relevant person in charge of MEXC responded that "the rumors are untrue" and said, "At present, MEXC is increasing its global layout and making positive progress in overseas business. In the future, it will continue to adhere to the user-centered approach. Principle layout of the global market".

After MEXC rejected the rumors, the price of MX retreated below 1.5 USDT on September 17.After MX fell below 1.5 USDT, MX began to break again strongly, rising to 1.93 USDT around 13:00 on September 18, an increase of more than 28%.

After the head of MEXC dispelled the rumors that MEXC was acquired on September 16, why did MX rise sharply again? It is still related to the rumors of MEXC being acquired.According to internal sources, the rumors of MEXC being acquired by Bybit should be true. Some investors also said in the community that they bought MX from 1.1 USDT.Who is Bybit? According to data from Coingecko, Bybit ranks third in derivatives exchanges based on open positions; Bybit ranks sixth in terms of 24-hour trading volume.Why the rumored object is Bybit? Some analysts said that firstly, Bybit is the world's top five derivatives exchange, with an annual profit of billions of dollars; secondly, after Bybit completely withdraws from China and moves overseas in 2020 and recently launched BitDAO, the Bybit ecosystem needs to be domestically and centralized. The spot market is complementary; again, Bybit is created for the domestic team, and there are no obstacles in language and culture.

And Bybit has been moving frequently recently.Bybit announced on June 6 the launch of BitDAO, a decentralized autonomous organization aimed at promoting the development of open finance, and completed $230 million in financing. Peter Thiel, Founders Fund, Pantera Capital, and Dragonfly Capital led the investment.

On August 10, BitDAO launched the first step of the DeFi ecosystem, auctioning 200 million BIT tokens on the Sushi MISO platform in the Netherlands, raising nearly 350 million U.S. dollars. As of press time, the market value of BIT is 410 million USDT and the market value of MX is 180 million USDT.In the future, BitDAO intends to launch various DeFi products, including an encrypted futures exchange and a decentralized version of Bybit.

After layout, Bybit has formed a centralized derivatives exchange and a decentralized DeFi ecosystem, and there is still a lack of a centralized spot exchange.MEXC is Bybit's choice? The crypto community will wait and see.

Arbitrum will continue to absorb the most advanced technology and actively promote the development of the expansion field.After the Ethereum expansion network Arbitrum One was officially launched and publicly tested, it has become the network with the largest amount of asset lock-ups in the Ethereum L2, even an order of magnitude higher than the second place. But in fact, this is only the first expansion network launched by Offchain Labs, and a parallel expansion technology with Arbitrum One will be launched in the future.For example, in the previous cooperation with social media and online forum Reddit, Arbitrum has stood out among dozens of expansion plans, and Reddit will use Arbitrum to expand its community points system (Community Points). The Arbitrum team told Lianwen, "According to our current expectations, there will be various industry-specific and company-specific Rollup solutions in the future. Multiple Rollups can run in parallel to increase the total capacity."At that time, Reddit conducted research and in-depth review of multiple Ethereum scalability solutions, and found that Arbitrum's Optimistic Rollups were the most promising expansion technology for the community points system, so it decided to adopt the Arbitrum solution, which will be launched on the Rinkeby testnet first. , And then migrate to the Ethereum mainnet.

As for the current expansion effect of Arbitrum One, the team said that there is still some room for improvement in the short term, but in the long run, it still needs to rely on the data sharding technology of Ethereum 2.0 in order to reduce transaction costs more significantly.In addition, we also chatted with the Arbitrum team about "the centralization risk of a single Sequencer", "views on other expansion technologies" and other topics.

What are the components of Arbitrum's complete solution?In fact, we are very curious about what components Arbitrum is built of as a novel and complex expansion technology, and what role AVM and ArbOS, which are often heard in the community, play in this agreement.

The Arbitrum team stated that Arbitrum consists of four parts, namely: smart contract of the agreement, AVM (virtual machine), ArbOS and asset bridge.Smart contract of the protocol: Sometimes called EthBridge, it refers to the smart contract of the Arbitrum Rollup protocol on Ethereum. It ensures that the business above this layer can run correctly, and provides mediation if there is a dispute in the Arbitrum protocol. "Logic. (Chain note: The term Arbitrum comes from Arbitrium, which means arbitration, that is, "dispute resolution").
