GROUPED MULTILAYER PRACTICAL BYZANTINE FAULT TOLERANCE ALGORITHM: A PRACTICAL BYZANTINE FAULT TOLERANCE CONSENSUS ALGORITHM OPTIMIZED FOR DIGITAL ASSET TRADING SCENARIOS

Based on the practical Byzantine fault tolerance algorithm (PBFT), a grouped multilayer PBFT consensus algorithm (GM-PBFT) is proposed to be applied to digital asset transactions in view of the problems with excessive communication complexity and low consensus efficiency found in the current consensus mechanism for digital asset transactions.Firstl
