Unjail a Validator
For whatever reason your validator becomes jailed while partaking in the Union network, you can unjail your validator with a simple command.
The Unjail command
Once your validator is unbonded and jailed, you can use the unjail command to rejoin the active set.
The unjail command is a transaction command from the slashing module and can be submitted like this:
uniond tx slashing unjail --from $KEY_NAME
Epoch Staking & Validator Set Updates
Just like creating your validator, once you’ve unjailed your validator, they’ll rejoin the active set at the end of the current epoch.
