A Scalable Multi-Layer PBFT Consensus for Blockchain [PDF]
IEEE Transactions on Parallel and Distributed Systems, 2021 Practical Byzantine Fault Tolerance (PBFT) consensus mechanism shows a great potential to break the performance bottleneck of the Proof-of-Work (PoW) based blockchain systems, which typically support only dozens of transactions per second and require minutes to hours for transaction confirmation. However, due to frequent inter-node communications, PBFT
