What is slashing in proof of stake?

Slashing is the penalty a proof-of-stake network applies when a validator breaks the rules, for example by signing two conflicting blocks or staying offline too long. Part of the stake is removed, and delegators share the loss.

What triggers it

  • Double signing: signing two different blocks at the same height, which looks like an attack on the network.
  • Long downtime: missing too many blocks in a row on networks that penalise it.

Who pays

The penalty is taken from the validator's total stake, which includes delegated funds, so everyone delegated to that validator shares the loss proportionally.

How a good validator avoids it

Slashing is rare for careful operators. Evernodes runs monitored infrastructure with safeguards against double signing, and publishes every slashing or jailing incident on its network status page.

How common is slashing?
Rare among professional validators, but it cannot be ruled out entirely, which is why it is listed as a risk of staking.
