DRT-PBFT: A Novel PBFT-Optimized Consensus Algorithm for Blockchain Based on Dynamic Reputation Tree

Future Internet
While the practical Byzantine fault tolerance (PBFT) consensus algorithm provides excellent theoretical fault tolerance, its performance in practical blockchain applications is often constrained by high communication overhead, especially in scenarios with limited node resources and high mobility, such as Vehicular Ad hoc Networks (VANETs).
