Workload-based randomization byzantine fault tolerance consensus protocol
High-Confidence Computing, 2022 This paper introduces a new Byzantine fault tolerance protocol called workload-based randomization Byzantine fault tolerance protocol (WRBFT). Improvements are made to the Practical Byzantine Fault Tolerance (PBFT), which has an important position in the

Efficient Byzantine Fault-Tolerance [PDF]
IEEE Transactions on Computers, 2013 We present two asynchronous Byzantine fault-tolerant state machine replication (BFT) algorithms, which improve previous algorithms in terms of several metrics. First, they require only 2f+1 replicas, instead of the usual 3f+1. Second, the trusted service in which this reduction of replicas is based is quite simple, making a verified implementation ...

Joint Reputation Based Grouping and Hierarchical Byzantine Fault Tolerance Consensus Protocol
IEEE Access, 2023 Consensus protocol has challenges in terms of low consensus efficiency and centralization, as well as poor fault tolerance. A joint reputation model based grouping and hierarchical byzantine fault tolerance consensus protocol has been proposed.

Flexible Byzantine Fault Tolerance [PDF]
Proceedings of the 2019 ACM SIGSAC Conference on Computer and Communications Security, 2019 This paper introduces Flexible BFT, a new approach for BFT consensus solution design revolving around two pillars, stronger resilience and diversity. The first pillar, stronger resilience, involves a new fault model called alive-but-corrupt faults. Alive-but-corrupt replicas may arbitrarily deviate from the protocol in an attempt to break safety of the

On Probabilistic Byzantine Fault Tolerance
CoRR, 2020 Byzantine fault tolerance (BFT) has been extensively studied in distributed trustless systems to guarantee system's functioning when up to 1/3 Byzantine processes exist. Despite a plethora of previous work in BFT systems, they are mainly concerned about common knowledge deducible from the states of all participant processes.

Byzantine Fault-Tolerant Causal Ordering
Proceedings of the 24th International Conference on Distributed Computing and Networking, 2023 Causal ordering in an asynchronous system has many applications in distributed computing, including in replicated databases and real-time collaborative software. Previous work in the area focused on ordering point-to-point messages in a fault-free setting, and on ordering broadcasts under various fault models.
