May 1, 2026May 2026 monthly summary: Delivered major GLOAS integration for Caplin with enshrined proposer-builder separation (ePBS), updated consensus-spec alignment, and targeted stability fixes to the fork-choice and syncing path. Implemented Caplin P2P private key persistence to the datadir, ensuring ENR stability across restarts. Introduced per-directory Caplin consensus spec maps to improve clarity and governance of consensus-critical changes. Fixed critical reliability issues including mainnet resilience after the GLOAS merge, infinite loop in state loading, nil-panic guards, and improved liveness/UX by suppressing noisy shutdown warnings and correcting the liveness endpoint behavior. These efforts reduced restart risk, accelerated recovery after outages, and provided clearer specification governance for ongoing Caplin development.

Oct 1, 2024For 2024-10, delivered centralized elapsed time measurement utilities to standardize timing and metrics across epoch processing in erigon, improving observability, readability, and maintainability. Implemented a TimeMeasure struct and ObserveElapsedTime, enabling consistent timing across modules and easier performance diagnostics. This work includes a targeted refactor in ProcessEpoch as part of issue #12545 (commit e1f959c5fb3614b9dd633bb410b20b7eb8deb075), aligning timing instrumentation with broader monitoring goals.
