According to the Odaily Planet Daily report, Ethereum Lianchuang Vitalik Buterin issued an article pointing out that the L2 protocol has four key areas that can be improved: 1. More efficient use of bytes through data compression; 2. Optimistic data technology, using L1 only under special circumstances. Protect L2; 3. Continuously improve the implementation of relevant constraints; 4. Continue to improve security. He also said that Ethereum is no longer just a financial ecosystem, but a full-stack alternative to most "centralized technologies" and even provides some things that centralized technologies do not have (such as governance-related applications) , this broader ecosystem now needs to be taken into account.
