According to Wu Blockchain, Base has released a postmortem report on the two mainnet halts that occurred on June 25 and 26. The report states that both incidents were caused by the same Sequencer block construction logic bug, which led to the creation of blocks containing invalid state transitions. This resulted in network halts lasting approximately 116 minutes and 20 minutes, respectively. Base confirmed that on-chain funds were not affected, the bug has been fixed, and they plan to further enhance protocol fuzz testing, load testing, and network recovery mechanisms to reduce the risk of similar incidents in the future. https://www.(wublock123.com)/news/base-postmortem-two-mainnet-halts-sequencer-block-construction-bug-63597
