Month: 2025-09 — Delivered centralized vkey hashing refactors across agglayer/provers and agglayer, leveraging the agglayer-primitives library to consolidate hashing logic, remove redundant hashing, and update dependencies. This work standardizes hashing for verification keys, improves reliability, and reduces maintenance burden by providing a single source of truth. No separate major bug fixes were recorded this month; instead, the refactor mitigates risk by addressing duplication and inconsistency in the hashing flow. The changes prepare the system for future enhancements in verification-key processing and notifier integration. Key commits include 166c6de6a28a262d36568db08535f6c1663d4467 (provers) and 8381f539eeb7bff97ecbd2cb5bbea673167f98bd (agglayer).

During August 2025, the agglayer team completed a major hashing system overhaul to improve performance, security, and maintainability. We adopted Keccak256Hasher as the standard hashing mechanism, removed the generic Hasher trait, upgraded related dependencies, and moved empty-hash calculations to compile time to eliminate runtime overhead. These changes reduce per-call hashing costs, ensure more consistent behavior across modules, and simplify the hashing API for future enhancements. The work establishes a solid foundation for further cryptographic optimizations and reliability improvements across the repository.
