According to reports from Wu, Max Resnick, the chief economist of the Solana ecosystem development company Anza, has submitted the Solana Improvement Proposal SIMD-0301: Asynchronous Execution. This proposal eliminates replay bottlenecks in the consensus critical path by introducing asynchronous execution. Compared to traditional synchronous execution models, SIMD-0301 allows validators to vote before block execution, significantly reducing confirmation delays under the Alpenglow consensus mechanism and supporting multi-lead concurrency and pipelined consensus. Currently, this proposal is still in draft stage and must meet several prerequisites to be activated, with plans for implementation after the new Alpenglow consensus mechanism is enabled.
