Solana Proposal Aims to Enhance Blockchain Efficiency with Asynchronous Execution

According to PANews, Solana developer Max Resnick has submitted a proposal, SIMD-301, to introduce asynchronous execution capabilities to the blockchain. This proposal seeks to allow validator nodes to vote before the completion of block transaction execution, significantly reducing block confirmation times. It also sets the stage for future developments in multi-leader concurrency (MCL) and pipelined consensus mechanisms. Key changes outlined in the proposal include the removal of the BankHash field from the voting structure, the introduction of a static block validation check mechanism, and enabling validator nodes to vote after passing static checks without waiting for transaction execution to complete. The proposal emphasizes the need to prevent malicious nodes from submitting time-consuming transactions that could result in empty blocks. The asynchronous execution feature will be activated in phases through a feature flag and is expected to be deployed following the completion of the Alpenglow upgrade.
