Prysm Bug Knocks Ethereum Consensus Participation After Fusaka

Shortly after the Fusaka network upgrade, the Ethereum network saw a sharp drop in validator participation after a bug in the Prysm consensus client knocked a chunk of votes offline.

According to a Thursday Prysm announcement, version v7.0.0 of the client unnecessarily generated old states while processing outdated attestations, a flaw that Prysm core developer Terence Tsao said prevented the nodes from functioning correctly. Developers recommended that users launch the client with the “–disable-last-epoch-targets” flag as a temporary workaround.
