I know Bitcoin runs on a POW (Proof of work) concept and that there is a side chain of Ethereum using PoA but other than that what other blockchains/crypto currencies run using these or different protocols?
Here you can read the difference between consensus algorithms, how do they work and who uses them. There are more consensus algorithms (Proof-of-Importance in NEM, Proof-of-Elapsed-Time and other).
