Ethereum experienced a rare slashing event on Wednesday, with 39 validators penalized, according to blockchain explorer Beaconcha.in.
The validators were tied to the SSV Network, a distributed validator technology (DVT) protocol that decentralizes staking infrastructure by splitting validator keys across multiple operators.
Despite the scale of the incident, SSV founder Alon Muroch emphasized that the protocol itself was not compromised. Instead, the penalties stemmed from operator-side infrastructure issues involving third-party staking providers using SSV.
One cluster of slashed validators was tied to Ankr, a liquid staking provider. According to Muroch, routine maintenance on Ankr’s systems triggered the event. A second slashing involved a validator cluster that had migrated from Allnodes two months earlier. Investigators believe a secondary validator setup caused the duplicate signing that led to penalties.
In total, 39 validators were slashed, making this one of the largest
