I was under the impression that the oracle voting built into the wallet was a consensus protocol. What would you consider it then? Maybe you have not used recent versions? The proof of person to verify is something completely different...
Consensus Algorithms in Blockchain
A consensus algorithm is a procedure through which all the peers of the Blockchain network reach a common agreement about the present state of the distributed ledger.

Agree, but this is not consensus. This is how you can join the "validators pool", not how blocks are validated/added to the blockchain (consensus).
