TechFlow News, June 1: According to The Block, the Sui Foundation released an incident report on May 31 disclosing three consecutive outages on its mainnet from May 29 to 30, all stemming from two independent bugs introduced in the v1.72 software upgrade. The first two outages were caused by a gas fee calculation error triggered by the newly launched “address balance” feature—funds were deducted even when transactions were canceled, resulting in negative account balances and subsequent validator node crashes. The third outage was triggered by a latent vulnerability in the random number generator during node restarts, preventing the network’s epoch from closing normally. The Sui Foundation stated that all known issues have now been resolved, user funds remained unaffected throughout the incidents, and no settled transactions were rolled back. The Foundation plans to further enhance its fault-tolerance mechanisms to ensure that future similar vulnerabilities impact only individual transactions rather than causing network-wide outages.
