Slashing is a penalty mechanism used in blockchain networks, particularly in Proof-of-Stake and Delegated Proof-of-Stake consensus algorithms. Its primary purpose is to discourage malicious or negligent behavior by network validators or stakers. Slashing involves the confiscation or 'slashing' of a portion of a validator's or staker's cryptocurrency holdings as a punishment for violating network rules or acting against the network's best interests.
