Consensus Mechanisms

With no need for Proof of Work (PoW) in a permissioned network, GoQuorum instead implements multiple consensus mechanisms that are more appropriate for consortium chains:

• Raft-based

  A consensus model for faster blocktimes, transaction finality, and on-demand block creation. See Raft-based documentation for more information

• Istanbul BFT (Byzantine Fault Tolerance)

  A PBFT-inspired consensus algorithm with immediate transaction finality, by AMIS. See IBFT documentation, the RPC API, and this technical web article.

• Clique Proof of Authority (PoA)

  A default POA consensus algorithm bundled with Go Ethereum. See Clique POA Consensus Documentation and a guide to setup clique json with puppeth
