Original Title: Ethereum saw validator participation drop by 25% at one point after Fusaka upgrade… Almost lost finality
Original Link:
Ethereum experienced a sharp 25% drop in validator participation immediately following the Fusaka(Fusaka) network upgrade.
This was related to a bug in the Prysm consensus client. The Prysm v7.0.0 version unnecessarily generated outdated states, causing nodes to malfunction, which led to decreased validator participation. At one point, the Ethereum network recorded a 75% sync participation rate and a 74.7% voting rate, barely surpassing the two-thirds threshold required to maintain finality.
The network has since recovered to a 99% participation rate, but at the time of the incident, the proportion of validators using the Prysm client dropped from 22.71% to 18%.
Similar issues have occurred in the past. In May 2023, bugs in the Prysm and Teku clients caused Ethereum mainnet to lose finality, and at that time, Prysm controlled more than two-thirds of the nodes, which could have led to an even more severe situation.
The problem of a lack of diversity among Ethereum clients has resurfaced. Lighthouse(Lighthouse) accounts for 52.55%, and Prysm for 18%, indicating that reliance on a single client remains high. Ethereum educator Anthony Sassano said, “If there had been a bug in Lighthouse, the network would have lost finality.”
