Ethereum Consensus Layer Client Prysm Releases Fusaka Mainnet December 4th Post-Mortem Analysis Report
BlockBeats News, December 14th: Ethereum consensus layer client Prysm released a postmortem analysis report on the Fusaka mainnet incident that occurred on December 4th. During the Fusaka upgrade period, almost all Prysm beacon nodes experienced resource exhaustion when processing specific attestations, leading to delayed responses to validator requests, resulting in a significant number of missed blocks and attestations.
The incident affected a range from epoch 411439 to 411480, spanning 42 epochs, with 248 blocks missing out of 1344 slots, representing an approximately 18.5% omission rate. The network participation rate dropped to 75%, and validators lost an estimated 382 ETH in rewards. The root cause was Prysm receiving attestations from potentially out-of-sync nodes with the mainnet, referencing the block root of the previous epoch. To validate their legitimacy, Prysm repeatedly replayed old epoch states and performed a resource-intensive epoch transition, causing nodes to experience resource exhaustion under high concurrency.
The Prysm team provided a temporary solution by enabling the --disable-last-epoch-target parameter in version 7.0.0. Subsequently released versions 7.0.1 and 7.1.0 include a long-term fix that validates attestations using the head state to avoid replaying historical states repeatedly.
