I know POW is the Consensus algorithm of ethereum now, and it will be changed to POS. But does ethereum has other Consensus algorithm besides POW and POS? I heard from a man there are other Consensus algorithm in ethereum but I don't know if it is true. thank you .
It would be nice to compile a list of available consensus algorithms. I marked this answer as "community wiki", feel free to add to the list.
- Proof of Work (PoW) - currently in Mainnet
- Proof of Stake (PoS) - currently in research
- Proof of Authority (PoA):
- Clique - Geth, Parity and other clients EIP-225
- AuRa (Authority Round) - Parity
- Raft - Quorum (Geth fork)
- IBFT (Istanbul BFT) - Quorum (Geth fork)
- IBFT 2.0 - Pantheon (Java Ethereum client)
