If a validator was automatically unbonded due to downtime and wishes to come back online &
possibly rejoin the bonded set, it must send MsgUnjail:
Copy
// MsgUnjail is an sdk.Msg used for unjailing a jailed validator, thus returning// them into the bonded validator set, so they can begin receiving provisions// and rewards again.messageMsgUnjail{string validator_addr =1;}
Below is a pseudocode of the MsgSrv/Unjail RPC:
Copy
unjail(tx MsgUnjail)
validator = getValidator(tx.ValidatorAddr)
if validator == nil
fail with "No validator found"
if getSelfDelegation(validator) == 0
fail with "validator must self delegate before unjailing"
if !validator.Jailed
fail with "Validator not jailed, cannot unjail"
info = GetValidatorSigningInfo(operator)
if info.Tombstoned
fail with "Tombstoned validator cannot be unjailed"
if block time < info.JailedUntil
fail with "Validator still jailed, cannot unjail until period has expired"
validator.Jailed = false
setValidator(validator)
return
If the validator has enough stake to be in the top n = MaximumBondedValidators, it will be automatically rebonded,
and all delegators still delegated to the validator will be rebonded and begin to again collect
provisions and rewards.
