Dec 1, 2024

Month: 2024-12 — Focused on strengthening configuration management for the shardeum repository with JSON-based, multi-file config loading and dynamic runtime adjustments. Implementations reduced deployment risk by preserving environment overrides, adding robust error handling, and introducing new configuration knobs (formingNodesPerCycle, flexibleRotationDelta) to support faster, safer rollouts without code changes. The work enables more flexible operations in the P2P server and improves resilience in production configurations.
