Month: 2024-10 — Monthly summary for EspressoSystems/espresso-network focusing on reliability improvements to LightClient history retention and pruning logic. This month, a bug fix corrected the pruning condition in LightClient.updateStateHistory, ensuring the state history retention period is enforced using the most recent state instead of the upcoming block timestamp. Tests were updated to reflect the corrected behavior, improving confidence in state retention correctness and preventing growth of outdated state entries. The work reduces risk in cross-node state synchronization and improves long-term network stability.
