Ethereum co-founder Vitalik Buterin has shifted his stance to support native rollups, a significant change from his previous opposition. Buterin's initial concerns centered around the immaturity of ZK-EVM technology and the limitations of native rollup precompiles, which could only operate in either ZK or Optimistic modes. This limitation risked forcing Layer 2 solutions to adopt long withdrawal periods, potentially harming Ethereum's composability and leading to more multisig bridges. However, the timeline for Ethereum's Layer 1 to fully embrace ZK technology is now aligning with the progress of introducing native rollup precompiles, addressing these core issues. This development marks a pivotal moment in Ethereum's scalability strategy, as the ecosystem moves towards more efficient and secure rollup solutions.
