SSV Network 13

On September 10, Ethereum’s Beacon Chain slashed 40 validators for publishing conflicting attestations, with initial reports implicating StakeFi, Allnodes, and SSV Network. Further investigation revealed most were tied to Ankr, with individual penalties around $1,300 per validator. Ethereum core developer Preston Vanloon explained that such errors typically occur when validator keys are run across multiple environments, causing nodes to see different chain views and double-sign. Slashed validators must continue duties until exited or face additional liveness penalties. While mass slashing is rare—only 15 cases this year—past incidents like Bitcoin Suisse’s $200,000 loss in 2023 highlight the financial risks of operational mistakes in Ethereum’s proof-of-stake system.
