Optimistic Byzantine Fault Tolerance
International Journal of Parallel, Emergent and Distributed Systems, 2015 The primary concern of traditional Byzantine fault tolerance is to ensure strong replica consistency by executing incoming requests sequentially according to a total order.

Multi-Threshold Byzantine Fault Tolerance [PDF]
Proceedings of the 2021 ACM SIGSAC Conference on Computer and Communications Security, 2021 Classic Byzantine fault tolerant (BFT) protocols are designed for a specific timing model, most often one of the following: synchronous, asynchronous or partially synchronous.

Byzantine fault tolerance for nondeterministic applications [PDF]
Third IEEE International Symposium on Dependable, Autonomic and Secure Computing (DASC 2007), 2007 All practical applications contain some degree of nondeterminism. When such applications are replicated to achieve Byzantine fault tolerance (BFT), their nondeterministic operations must be controlled to ensure replica consistency.

Egalitarian Byzantine Fault Tolerance [PDF]
2021 IEEE 26th Pacific Rim International Symposium on Dependable Computing (PRDC), 2021 Minimizing end-to-end latency in geo-replicated systems usually makes it necessary to compromise on resilience, resource efficiency, or throughput performance, because existing approaches either tolerate only crashes, require additional replicas, or rely on a global leader for consensus.

Strengthened Fault Tolerance in Byzantine Fault Tolerant Replication [PDF]
2021 IEEE 41st International Conference on Distributed Computing Systems (ICDCS), 2021 Byzantine fault tolerant (BFT) state machine replication (SMR) is an important building block for constructing permissioned blockchain systems. In contrast to Nakamoto Consensus where any block obtains higher assurance as buried deeper in the blockchain, in BFT SMR, any committed block is secure has a fixed resilience threshold.

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
