Sui publishes post-mortem after mainnet stall halted transactions for six hours

Sui Foundation published a post-mortem detailing a six-hour mainnet stall on January 15, caused by an edge-case bug in consensus commit logic. This led to validators processing conflicting transactions differently under specific garbage-collection conditions, resulting in divergent checkpoint digests. The network automatically halted to prevent inconsistent state finalization, prioritizing safety over availability. No forks, rollbacks, or fund losses occurred, and read operations remained functional. Sui is implementing improvements for faster recovery and enhanced testing to prevent similar issues, confirming the safety mechanisms worked as intended.
