About 10 hours ago, more than 75 verifiers of the Ethereum 2.0 beacon chain main network were fined by Slash (the fine was collected from the 32 ETH pledged in the node). According to Beaconscan data, the confiscated nodes this time involved the PoS service provider Staked.us, and the total number of confiscated nodes in the entire Ethereum 2.0 network so far is 114.
Rudy, Marketing Director of InfStones, said that the reason for being slashed is mostly due to double-signing of blocks, and the specific operation should be due to operational errors during server migration or backup. The node that is slashed will be kicked out of the validator team, and part of the pledge will be fined and cannot be retrieved before Ethereum 2.0 supports transactions. This also means that close to 2400 ETH can no longer participate in the pledge income. Calculated at 10%, the indirect loss exceeds 200 ETH.
