 Proof-of-authority requires trusting a set of authorized signers that are set in the [genesis block](/glossary/#genesis-block). In most current implementations, all authorized signers retain equal power and privileges when determining consensus of the chain. The idea behind reputation staking is every authorized validator is well-known to everyone through things like know your customer (KYC), or by having a well-known organization being the only validator—this way if a validator does anything wrong, their identity is known.
 
-Proof-of-Authority has different implementations, but the standard Ethereum implementation is **clique**, which implements [EIP-225](https://eips.ethereum.org/EIPS/eip-225). Clique is developer-friendly and an easy-to-implement standard, supporting all client syncing types. Other implementations include [IBFT 2.0](https://besu.hyperledger.org/stable/private-networks/concepts/poa) and [Aura](https://openethereum.github.io/Chain-specification).
