What went fallacious?
Slashing happens when validators act towards consensus guidelines, typically by publishing contradictory attestations.
Preston Vanloon, an Ethereum core developer, explained that such errors often seem when validator keys are run throughout a number of environments. In that state of affairs, nodes might even see completely different views of the chain, resulting in double-signing and computerized penalties.
