Prysm Bug Cost Ethereum Validators Over $1 Million After Fusaka Upgrade

Ethereum consensus client Prysm said validators missed out on 382 ETH, equivalent to more than $1 million, after a software bug triggered network disruptions shortly after the recent Fusaka upgrade. The incident, detailed in a post-mortem titled “Fusaka Mainnet Prysm incident,” stemmed from a resource exhaustion event that affected nearly all Prysm nodes and led to missed blocks and attestations. What Caused Prysm’s Outage? According to Offchain Labs, the developer behind Prysm, the problem emerged on December 4 when a previously introduced bug caused delays in validator requests. Those delays resulted in missed blocks and attestations across the network source: https://beincrypto.com/ethereum-validators-lost-over-1-million-to-prysm-bug/
