The Ethcore Parity wiki states that it supports 'Proof of Authority Chains'. What distributed byzantine consensus mechanism is used?

No actual consensus mechanism is used.

Some nodes/keys have the right to sign blocks (configured in the example json you see at https://github.com/ethcore/parity/wiki/Proof%20of%20Authority%20Chains ), others don't.

As the text says, this is only for demo/development purposes. An actual consensus mechanism will need to be plugged in later.


Seems like now Parity is called OpenEthereum, which includes a consortium consensus algorithm called Aura
