Base Mainnet Suffers Two Block Production Outages in June: Sequencer Bug Halts Block Production, Funds Safe
Base released an analysis report on June 28 detailing two block production interruptions on June 25 and 26, lasting 116 and 20 minutes respectively. The root cause was a sequencer block-building logic bug where old journal state was not cleared after a failed transaction, leading to gas calculation errors and invalid state transitions. Funds remained safe. Base has deployed a fix and plans to enhance fuzz testing, stress testing, and introduce a rapid recovery mechanism.
