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.

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 ...

Multiple entry point PBFT for IoT systems
GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020Practical Byzantine Fault Tolerance (PBFT) consensus algorithm is unsuitable for Internet of things (IoT) applications due to the need for a single view leader. In this work we propose to augment PBFT with a contention-based bandwidth reservation phase that allows any ordering node to initiate a new consensus round.
