Jan 1, 2026

January 2026 highlights for lambdaclass/ethereum_rust: Delivered a unified multisync tool enabling parallel syncing across hoodi, sepolia, and mainnet via Docker Compose, with configurable environment variables and timeouts, CI-driven validation, and Slack status notifications improving reliability and operator visibility. Introduced Local Build Configurability to support low-bandwidth builds by adding the --builder.max-blobs CLI flag (EIP-7872), boosting local build throughput while respecting protocol limits. Enhanced observability and triage with Loki logs instance filtering, enabling per-instance log views. Improved debugging and stability with more informative temporary DB access errors, reducing time-to-diagnose. Maintained CI/devops hygiene by reverting a daily engine test workaround and addressing port collisions for ethereum-metrics-exporter, and removing unnecessary metrics setup to stabilize server-sync workflows. These efforts collectively reduce time-to-value for cross-network deployments, improve reliability, and expand support for developer workflows.
