Concurrency Testing of PBFT: How do different exploration strategies perform for detecting concurrency bugs in PBFT?

, 2023
Consensus algorithms, as well as distributed systems in general, are vulnerable to concurrency bugs due to non-determinism. Such bugs are hard to detect since it is necessary to test using a lot of different scenarios and even then, there is no guarantee

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).

PBFT vs proof-of-authority: applying the CAP theorem to permissioned blockchain

, 2017
Permissioned blockchains are arising as a solution to federate companies prompting accountable interactions. A variety of consensus algorithms for such blockchains have been proposed, each of which has different benefits and drawbacks. Proof-of-Authority
