## Definition

Slashing is the punishment built into proof-of-stake networks. If a validator signs conflicting blocks, stays offline for too long, or otherwise misbehaves, the network destroys part of their stake.

The threat of slashing is what makes proof of stake secure. Stakers who delegate to a validator can also be exposed to slashing, which is why choosing a reputable operator matters.
