Proof of Authority (PoA)

PoA is variant on the Proof of Stake consensus method. Rather than user's voting on the version of events recorded in the ledger with voice in proportion to the size of their staked capital, validators have equal votes and earn them in virtue of staking their personal reputation on their decision. PoA was first employed by the PoA network, which launched as a sidechain of the Ethereum network. Participants in the PoA network acted as public notaries. To participate in the validation process, notaries registered their physical address and identity with the network, implying that their reputation is at stake.
