Sui Foundation releases analysis report on three mainnet outages: consecutive interruptions caused by Gas injection logic and randomness state bug

Foresight News reports that the Sui Foundation has released an analysis report on three mainnet outages. The first two outages were caused by a crash vulnerability that occurred when the Gas injection logic, introduced in version 1.72, interacted with address balances. The team initially restored the network through a temporary fix, but this solution had a known low-probability issue that led to the second outage. The third outage occurred during the epoch transition on May 29. After validators restarted, they failed to correctly save the randomness state, causing distributed key generation (DKG) to fail and not persist, ultimately preventing the epoch from closing properly. Throughout the three outages, user funds were unaffected and the network did not roll back any confirmed transactions. The Sui core team has now fixed all known issues and network activity has returned to normal.
