Nov 1, 2024November 2024: Ethereum Execution Specs — Focused on improving runtime configurability, correctness after forks, and cross-fork robustness. Key outcomes: a URL-based configuration for the EVM Tool Daemon enabling dynamic runtime control without restarts; a critical fix to fork block gas accounting for Cancun ensuring zeroed initial blob gas values and correct propagation; a refactor unifying transaction handling across hard forks and upgrading RLP to ethereum-rlp with enhanced invalid-signature error handling, improving robustness and consistency across forks. Business impact: faster experimentation, fewer post-fork discrepancies, reduced maintenance cost, and stronger security posture.

Oct 1, 2024In 2024-10, delivered targeted improvements to error handling in ethereum/execution-specs, consolidating RLP decoding errors under EthereumException and introducing a new InvalidSenderError to improve fault isolation and client-facing messaging. Updated tests to reflect broader exception catching and replaced legacy InvalidBlock paths for transactions from accounts with code. These changes reduce ambiguity, improve error reporting, and support more robust client behavior for validators and wallets.
