Hooks

This section contains a description of the module's hooks. Hooks are operations that are executed automatically when events are raised.

Staking hooks

The slashing module implements the StakingHooks defined in x/staking and are used as record-keeping of validators information. During the app initialization, these hooks should be registered in the staking module struct.

The following hooks impact the slashing state:

AfterValidatorBonded creates a ValidatorSigningInfo instance as described in the following section.
AfterValidatorCreated stores a validator's consensus key.
AfterValidatorRemoved removes a validator's consensus key.

Validator Bonded

Upon successful first-time bonding of a new validator, we create a new ValidatorSigningInfo structure for the now-bonded validator, which StartHeight of the current block.

onValidatorBonded(address sdk.ValAddress)

  signingInfo, found = GetValidatorSigningInfo(address)
  if !found {
    signingInfo = ValidatorSigningInfo {
      StartHeight         : CurrentHeight,
      IndexOffset         : 0,
      JailedUntil         : time.Unix(0, 0),
      Tombstone           : false,
      MissedBloskCounter  : 0
    }
    setValidatorSigningInfo(signingInfo)
  }

  return
