Vitalik's new article: We should continue to adhere to the L2 expansion route, but L2 needs to fulfill its promises, such as contributing a certain amount of income to support ETH

Vitalik published another new article today, outlining Ethereum Layer1, Layer2, and future expansion issues. In the article, Vitalik mentioned that a possible shortcut to expansion is to abandon Layer2 and complete all work through Layer1 with a higher gas limit, but this approach will undermine the advantages of Ethereum's current social structure, which is very effective in obtaining different forms of research, development, and ecosystem building culture at the same time. Therefore, we should stick to it and continue to expand mainly through Layer2, but make sure that Layer2 does fulfill the promises they should fulfill. This means that we need to do the following: Layer1 needs to accelerate the expansion of Blob; Layer11 also needs to moderately expand EVM and increase gas limits; Layer2 needs to continue to improve security; L2s and wallets need to accelerate improvements and standardize interoperability; Layer2 deposit and withdrawal times need to become faster; as long as basic interoperability requirements are met, heterogeneous Layer2 is not a problem; ETH's economic model should be clarified, and it is necessary to ensure that ETH can continue to accumulate value even in a Layer2-intensive world. In the content about the ETH economic model, Vitalik also mentioned that Layer2 is encouraged to support ETH by contributing a certain percentage of fees, which can be achieved by destroying part of the fees, permanently staking and donating the proceeds to Ethereum ecosystem public products or some other schemes.
