Anza Chief Economist Submits Solana SIMD-0301: Eliminating Consensus Replay Bottleneck Through Asynchronous Execution

According to Wu Shuo, Max Resnick, Chief Economist of Solana ecosystem development company Anza, has submitted a Solana Improvement Proposal (SIMD-0301): Asynchronous Execution. This proposal introduces asynchronous execution to eliminate the replay bottleneck in the consensus critical path (i.e., the process where validators need to re-execute transactions within the block). Compared to the traditional synchronous execution mode, where validators must wait for the replay of transactions to complete before voting, SIMD-0301 allows validators to vote before block execution, thereby significantly reducing confirmation latency under the Alpenglow consensus mechanism and supporting Multi-Consensus Leadership (MCL) and pipeline consensus. Currently, the proposal is still in the draft stage and requires multiple prerequisites to be met before activation. It is planned to be officially implemented after the new Alpenglow consensus mechanism is enabled.
