According to TechFlow, on October 17, Ethereum co-founder Vitalik Buterin published an article (Possible futures for the Ethereum protocol, part 2: The Surge) to explore the future development direction of the Ethereum protocol and put forward four key goals:

Achieve 100,000+ TPS on L1+L2; maintain the decentralization and robustness of L1; at least part of L2 fully inherits the core properties of Ethereum (trustless, open, and censorship-resistant); achieve maximum interoperability between L2s, making the Ethereum ecosystem more unified.

Vitalik emphasized that the current task is to complete the rollup-centric roadmap and solve related problems while maintaining the robustness and decentralization of Ethereum L1. The article discusses in detail technical directions such as data availability sampling, data compression, generalized Plasma, maturity of L2 proof system, cross-L2 interoperability improvements, and L1 execution expansion.

Vitalik pointed out that the main challenge facing the L2 ecosystem is that it is difficult for users to navigate, and the simplest methods often reintroduce trust assumptions. In order to realize the vision of L2 as part of Ethereum, it is necessary to make the user experience of the L2 ecosystem more unified. The article proposes a number of cross-L2 interoperability improvement suggestions, including chain-specific addresses, cross-chain payment request standardization, cross-chain exchanges and gas payments, light clients, etc.
