dBFT 2.0

    The NEO blockchain uses a highly advanced framework (dBFT 2.0) similar to Proof- of- Stake( PoS) called delegated byzantine fault tolerance, or dBFT. NEO’s dBFT 2.0 solves several inefficiencies that the first version of dBFT struggled with. DBFT 1.0 was occasionally susceptible to a single block fork, meaning that messaging problems between system nodes could frequently occur, resulting in network inefficiency.
