An Extensible Consensus Algorithm Based on PBFT
2019 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery (CyberC), 2019Practical Byzantine Fault Tolerance (PBFT) is a deterministic consensus algorithm, which is widely used in blockchain due to the advantage of no forks. However, PBFT still has some problems, such as not being suitable for dynamic networks, requiring large communication overhead, and not being able to identify Byzantine nodes.

QPoS: Decentralized Stake-Based Leader and Voter Selection in a PBFT System With Mobile Voters
IEEE Transactions on Network Science and EngineeringBoth Proof of Stake (PoS) and Delegated Proof of Stake (DPoS) consensus schemes for permissioned blockchains incur the risk of centralization of voting power in the hands of a small number of wealthy voters.

PBFT-based ordering service for IoT domains
2020 IEEE 92nd Vehicular Technology Conference (VTC2020-Fall), 2020This work proposes and evaluates a Practical Byzantine Fault Tolerance (PBFT)-inspired ordering service for IoT data collection and block formation in a permissioned blockchain environment. We implement an algorithm for atomic insertion of request to ordering service in which each ordering node can initiate insertion and lead the consensus protocol ...

When Honest Nodes in PBFT Consensus Meet Software Aging: SMP-Based Performability Evaluation
ICC 2025 - IEEE International Conference on CommunicationsAvailability and/or performance of PBFT (Practical Byzantine Fault Tolerance) consensus service has been widely studied. However, the existing studies overlook the situation of software aging of honest nodes, which can degrade system performance over ...
