The first validator fined on Ethereum 2.0 network

In the Ethereum 2.0 network, one of the validators lost part of the stake for block corruption. This was announced by lead developer Justin Drake.

A validator got slashed for a block equivocation, losing ~0.25 ETH. Do not try to run fancy validator redundancy that could bypass the slashing protections.https://t.co/gmhofdy7E4

The validator is fined 0.25 ETH on slot 6669. At the time of writing, his balance is below 32 ETH, so he cannot participate in the block release.

Over the last 24 hours, the validator participation rate is 96.99%.

Drake recalled that in the first phase of the Ethereum 2.0 launch, it was decided to ease sanctions for isolated incidents. Over time, the amount of the fine will return to 1 ETH.

Slashing penalties are designed to be lenient for isolated offences like these. Mass slashings are heavily penalised (if X% get slashed they lose ~3X% of their balance).

(Note also that the minimum slashing amount was reduced for genesis and will be increased back to 1 ETH.)

Earlier, Ethereum co-founder Vitalik Buterin said that fines are imposed for violation of the rules and malicious acts. In the first months of the protocol’s operation, they will not exceed a quarter of the stack size on the Medalla testnet.

Recall that the launch of the zero phase of Ethereum 2.0 took place on Tuesday, December 1.
