Ethereum is set to enhance its transaction execution capabilities with the upcoming 'Glamsterdam' hard fork, introducing parallel transaction execution to the Ethereum Virtual Machine (EVM). Developer Toni Wahrstätter announced that the core proposal, EIP-7928, will implement a "Block Access List" (BAL) to record accounts and storage areas accessed by a block, streamlining transaction effects visibility. This update will allow Ethereum clients like Geth and Nethermind to verify transactions in parallel, optimizing multi-core processor use. The hard fork will also introduce "batch prefetch" to preload data during block execution, speeding up transaction verification. Additionally, EIP-7928 will enable parallel "post-state root" calculations, reducing block validation bottlenecks. The update includes "snap sync v2" for faster node synchronization, enhancing network resilience. Tests indicate a fivefold increase in block verification speed on 6-core machines, potentially raising the block gas limit to 300 million. The Glamsterdam update marks a significant step in Ethereum's scalability efforts.
