CoinVoice has learned that Ethereum L2 network Starknet released a post-mortem report on the short-term mainnet outage this Monday, stating that the cause of the incident was a state inconsistency between the execution layer (blockifier) and the proof layer: under specific cross-function call and rollback combinations, the execution layer incorrectly recorded a rolled-back state, leading to transaction execution anomalies. The related transactions did not receive final confirmation from L1. This event triggered a blockchain reorganization, and approximately 18 minutes of on-chain activity was rolled back.
This is the second major outage since 2025. Previously, in September, a sequencer vulnerability caused over 5 hours of downtime and a rollback of about 1 hour of on-chain activity.
