Facebook’s cryptocurrency Libra uses LibraBFT, a Byzantine Fault Tolerance (BFT) consensus protocol. Libra is a derivative of another consensus protocol called HotStuff, which uses classical BFT algorithm. Facebook must have chosen a variation of dBFT in order to ensure that untrustworthy actors use its currency as a means of minimizing KYC and AML risks, according to proponents. NEO and NEO are not the only blockchain projects using BFT consensus protocols, as well, which combines verifiable random functions and BFT algorithms.
