slashing
Penalty that reduces a cryptocurrency validator's stake for misbehavior.
Slashing is a punishment mechanism used in blockchain networks that rely on validators to maintain the ledger. When a validator acts dishonestly—such as voting for conflicting blocks, going offline repeatedly, or attempting to manipulate the network—the protocol automatically destroys a portion of their deposited cryptocurrency. This financial penalty makes misbehavior costly.
Slashing exists because validators need incentives to stay honest. Instead of relying solely on reputation or trust, the system forces validators to risk their own money. When you see slashing mentioned in headlines, it usually means either a network is testing its security, or a validator has been caught breaking the rules. The size of the penalty varies by network and violation type.
