Slashing for bridge operators
Overview
Slashing is a mechanism that governs the behavior of validators and bridge operators on the Ronin blockchain. This page describes the slashing rules for bridge operators.
A "day" in the slashing rules refers to the period from midnight to midnight UTC.
Unavailability bridge operator
The system slashes bridge operators for not providing enough signatures. This is checked against a smart contract that records the number of the bridge operators' votes.
Tier 1 operator slashing
If a bridge operator misses more than 10% votes in a day, the operator doesn't earn the bridge rewards on that day. The operator's status is set to Punished.
Tier 2 operator slashing
If a bridge operator misses more than 30% votes in a day, the operator doesn't earn the bridge rewards for the next five days. The operator's status is set to Punished.
Penalty stacking
If a penalized operator is slashed again, their penalty is stacked. For example, if an operator gets tier-2 slashed on day 1, it will be penalized until day 5. Then, if the operator gets tier-1 slashed on day 2, it will be penalized until day 6. Finally, if the operator gets tier-2 slashed on day 4, it will be penalized until day 11.
If an operator gets penalized for 20 days (for example, at day 100, it's penalized until day 120), it will be removed from the operator set.
