Vitalik: Unless L2 can be "extremely scaled" or innovated, the original vision is no longer applicable.

According to ME News, on February 3 (UTC+8), Ethereum founder Vitalik Buterin posted on social media that "with the Ethereum mainnet (L1) scaling up and the gas limit plan significantly increasing, Layer 2 (L2), originally envisioned as 'brand sharding,' is no longer necessary. L2 cannot fully meet the characteristics that 'brand sharding' should have, and some projects may even remain in Phase 1 indefinitely to meet customer regulatory requirements. Therefore, L2 should be repositioned, no longer just pursuing scaling, but providing unique additional functions, such as privacy-dedicated virtual machines, application-specific efficiency, extreme scaling, non-financial application design such as social/identity/AI, and low latency or built-in oracles. Best practices for L2 include: at least maintaining the Phase 1 standard (otherwise it is essentially just a standalone L1 with bridging), and achieving interoperability with Ethereum as much as possible, while exploring integration with native Rollup pre-compilation (ZK-EVM verification) to achieve secure, trustless cross-chain operations and synchronous composability." Users should clearly understand the guarantees provided by L2. The L2 ecosystem will offer diverse choices: there are chains that rely entirely on Ethereum's trust and credit, as well as chains with varying degrees of interconnection, each focusing on different functions or application scenarios, truly achieving innovative additions rather than simply extending L1.
