**[Vitalik Buterin Proposes Ethereum Layer 2 Strategy Adjustment]** In February 2026, Vitalik Buterin published a post proposing an adjustment to Ethereum's Layer 2 strategy, acknowledging that the 2020 roadmap centered on "Rollups" has become misaligned with reality. Vitalik highlighted two core issues: the slow progress of Layer 2 decentralization, with some teams potentially never achieving full decentralization due to regulatory or business model constraints; and the faster-than-expected scaling of Ethereum Layer 1, where low fees have turned Layer 2 from a necessity into an optional solution for specific use cases. Vitalik proposed a "trust spectrum" framework, recognizing the differentiated positioning of Layer 2 solutions and suggesting improvements to cross-layer interaction efficiency through native Rollup precompiles and synchronized composability mechanisms. Mainstream Layer 2 teams responded differently to the proposal, showcasing strategic diversity.
