Sui releases report on mainnet outage: sustained disruption due to internal disagreement in validator consensus processing

Techub News reports that Sui has released a report regarding the mainnet outage on January 14. The cause of this incident was a persistent disruption due to internal disagreements in the validator consensus process. This failure prevented validators from certifying new checkpoints, resulting in transaction submission timeouts. The issue was unrelated to network congestion or transaction volume. Sui's checkpoint certification and isolation mechanisms promptly detected and contained the problem, preventing a user-visible fork by suspending the process. The network has resumed normal operation after validators deployed a fix and reprocessed the consensus data. Sui stated that no certified transactions were rolled back during this incident, and user funds remain secure.
