Vitalik: Unless L2 can "scale to the limit" or make a breakthrough, the original vision is no longer valid

BlockBeats News, February 3rd, Ethereum founder Vitalik Buterin posted on social media, stating, "With Ethereum's Layer 1 (L1) scaling and gas limit significantly increased, the original vision of 'brand-based sharding' for Layer 2 (L2) is no longer necessary. L2 cannot fully meet the intended features of 'brand-based sharding,' and some projects may even remain in Stage 1 indefinitely to meet customer regulatory requirements. Therefore, L2 should be repositioned to no longer simply pursue scalability but to provide unique additional features, such as a privacy-focused virtual machine, application-specific efficiency, maximum scalability, non-financial application designs like social/identity/AI, and features like low latency or built-in oracles."

Best practices for L2 include: maintaining at least Stage 1 standards (otherwise essentially just an independent L1 with bridging) and striving for interoperability with Ethereum as much as possible. Additionally, exploring integration with native Rollup precompiles (ZK-EVM verification) to achieve secure, trustless cross-chain operations and synchronous composability.

Users should have a clear understanding of the protections provided by L2. The L2 ecosystem will present diverse options: chains that fully rely on Ethereum's trust and credit and chains with varying degrees of association, each focusing on different functions or application scenarios, truly achieving innovative additions rather than just extending L1."
