The network said the first halt lasted 116 minutes and the second 20 minutes, with a later race condition and infrastructure issues slowing recovery.
Base said two mainnet outages on June 26 stemmed from a software bug in the sequencer (system that orders transactions) block-building logic. The bug preserved stale journal state after an invalid transaction failed, halting the network twice. The first interruption lasted 116 minutes and the second 20 minutes. Base added that a later race condition and infrastructure issues delayed recovery, and said it plans more fuzz testing (automated stress testing with random inputs) and recovery improvements.
