Proof-of-Authority is introduced by Microsoft on it's Azure network, the product features a built-in decentralized application (DApp or dApp) called the “Governance DApp” that provides consortium members with the authority to govern the network or delegate their voting power to others. Network participants can also delegate other nodes to vote on their behalf in the event that their primary nodes go offline, ensuring that all members maintain continual consensus participation.
Network administrators, in turn, can use on-chain voting to vote on and alter network authorities in a transparent and auditable manner.
