If you issue a certificate, you proof ownership via * challenge–response test that is validated by each node. If x% (like eg. 70%) of nodes agree that the test is passed, the block counts as validated and can be placed onto the chain. (Each node places the block on their chain and the hash must be same as hash of chain of majority of nodes)
A blockchain to verify ssl cert keys and changes may work. Though idk how consensus would be secured.
