How Does ‘Slashing’ in Pure PoS Systems Attempt to Solve ‘Nothing-at-Stake’?
Slashing is a punitive mechanism where a validator's staked cryptocurrency is partially or fully taken away (slashed) if they engage in malicious behavior, such as double-signing or attesting to conflicting blocks. This introduces a significant economic cost for misbehavior.
By making it financially harmful to vote on multiple forks, slashing provides a strong disincentive, thus addressing the 'nothing-at-stake' problem in pure PoS.
