Solana community launches SIMD-301 proposal aimed at implementing asynchronous execution functionality

According to the Solana Improvement Document (SIMD), developer Max Resnick submitted a SIMD-301 proposal aimed at implementing asynchronous execution functionality for blockchain. This proposal will allow verification nodes to vote before the completion of block transactions, significantly reducing block confirmation time and paving the way for subsequent multi leader concurrency (MCL) and pipeline consensus mechanisms. The core changes include: 1. Removing the BankHash field from the voting structure; 2. Introduce a static block verification and inspection mechanism; 3. Once the verification node passes the static check, it can vote without waiting for the transaction to complete. The proposal specifically points out the need to prevent the risk of empty blocks caused by malicious nodes submitting time-consuming transactions. This feature will be activated in stages through feature flags and is expected to be deployed after the Alpenglow upgrade is completed.
