Slashing a validator

The chain supports slashing of misbehaving validators through governance vote.

Proposal Message

The proposal should contain a single MsgSlashValidator (opens in a new tab) message for each validator that should be slashed.

Notes:

The slashing will occur when the proposal is passed, not the infraction_height.
The infraction_height must be set so that time(proposal pass height) - time(infraction_height) < unbonding period. Typically a good choice for infraction_height is the current height unless there is a recent unbonding undelegation/redelegation that should be included in the slash. In that case the infraction_height should be set prior to the initiation of the undelegation/redelegation.
Both tokens_at_infraction_height and slash_factor must be set correctly, otherwise undelegations and redelegations might be slashed disproportionately to the rest of the validator's stake. tokens_at_infraction_height * slash_factor determines the total amount of tokens to be slashed. Unbonding delegations and redelegations are first slashed by slash_factor, and then the remaining amount is taken from the validator's stake.
The x/staking HistoricalInfo query endpoint can be used to find the correct value for tokens_at_infraction_height.
See the MsgSlashValidator (opens in a new tab) inline comments for further details on the above requirements.

Example Proposal Json

Below is an example proposal JSON file to propose a slashing a validator's total bonded tokens (both user delegated and self-delegated) by 0.2 at block height 5000. In other words:

assuming that the proposal passes governance vote
assuming that the validator has 1000 total bonded tokens at height 5000
once the proposal is passed, the validator will lose 200 tokens
if there are unbonding undelegations and redelegations since height 5000, they will lose 0.2 of their stake, and the remaining will be taken from the validator for a total of 200 tokens lost
