Svmuu News: Base has officially released an analysis report on block production interruptions, revealing that the Base mainnet experienced two block production interruptions on June 25 and 26, lasting 116 minutes and 20 minutes, respectively. The security of on-chain assets was not affected, and funds remained secure at all times. The root cause of the incident was a vulnerability in the sequencer’s block-building logic: after a transaction execution failed, the old journal state was not properly cleared, leading to gas calculation errors during the execution of subsequent valid transactions. This, in turn, generated invalid state transition blocks, causing the entire L2 chain to halt block production.
Base stated that the issue has now been resolved through a patch. Moving forward, the team will strengthen the protocol’s fuzz testing and stress testing systems to identify potential malicious transaction paths, while also optimizing monitoring and operations processes. Additionally, the team plans to introduce a recovery mechanism to enhance rapid recovery capabilities in the event of similar incidents in the future.
