Though the heavier penalties are supposed to be easily avoided, just a day after the launch of the first phase of Ethereum 2.0 (ETH 2.0), the first validator has been 'slashed'.
According to BeaconScan.com, since the Phase 0 launched on December 1, one validator was already slashed yesterday.
Thank you brave validator https://t.co/9Evpf5tXB1— Agustín Aguilar
