Ethereum consensus client Prysm released a post-mortem on the Dec. 4 Fusaka mainnet incident, attributing the outage to resource exhaustion caused by costly state recomputation when processing certain attestations. The issue led to 41 missed epochs, network participation dropping to 75%, and validator reward losses of about 382 ETH. A temporary fix was applied via a runtime flag, followed by permanent changes to attestation validation logic in versions v7.0.1 and v7.1.0.https://t.co/JQVP8cENHm ...
