The Sui Foundation released a post-incident analysis report regarding the mainnet outage on January 14th, confirming that the six-hour-long downtime was caused by a security measure triggered by an edge case vulnerability in the consensus submission logic. This vulnerability led validators to produce different outputs, thereby preventing checkpoint certification. No forks, rollbacks, or fund losses occurred during the event, and read operations continued as normal. Planned improvements include speeding up inconsistency detection and strengthening testing.
