Learn how Proof of Stake networks enforce honest behavior

0 / 5 completedValidator Slashing
In Proof-of-Stake networks, validators must stake capital and behave honestly. Slashing is the economic penalty for protocol violations, ensuring network security through accountability.
What is Slashing?
Slashing is the mechanism that penalizes validators who act maliciously or negligently. When a validator violates protocol rules, a portion of their staked capital is destroyed (burned) or redistributed. This creates powerful economic disincentives against attacks.
Stake Burned
Slashed funds are permanently destroyed, not given to others
Economic Security
Attack cost must exceed potential gain
Protocol Defense
Automatic enforcement without manual intervention

Double Signing
Validator signs two different blocks at the same height, attempting to create conflicting chain history
Examples of This Violation:
- •Signing block A and B at height 1000
- •Creating fork to reverse transactions
- •Malicious chain reorg attempt

Why Slashing Matters
Economic Alignment
Validators risk real capital, aligning their incentives with network health. Honest behavior is profitable; attacks are expensive.
Nothing at Stake
Without slashing, validators could costlessly vote on multiple chains. Slashing makes attacks expensive, solving the nothing-at-stake problem.
Automatic Enforcement
Slashing is programmatic and deterministic. No manual intervention needed—the protocol automatically penalizes violations.
Critical Concept
Slashing isn't just punishment—it's the core security mechanism of Proof-of-Stake. By requiring validators to put capital at risk and threatening its destruction for misbehavior, PoS creates economic security without energy-intensive mining. The threat of slashing must be credible enough that attacking costs more than any potential gain.
