Byzantine Fault-Tolerant (BFT) protocols cover a broad spectrum of design dimensions from
infrastructure settings, such as the communication topology, to more technical features, such …

To reduce latency and communication overhead of asynchronous Byzantine Fault Tolerance
(BFT) consensus, an optimistic path is often added, with Ditto and BDT as state-of-the-art …

ABSTRACT State Machine Replication (SMR) allows implementation of faulttolerant systems
and secure critical infrastructure. The advent of cryptocurrencies has increased research …

Conventional Byzantine fault tolerance (BFT) requires replicated state machines to execute
deterministic operations only. In practice, numerous applications and scenarios, especially …

When put under stress, traditional state-machine replication protocols typically exhibit
response times that by far exceed the average level of normal-case operation. The common …

Multi-BFT consensus runs multiple leader-based consensus instances in parallel,
circumventing the leader bottleneck of a single instance. However, it contains an Achilles' …

The rapid advancement of technology has brought about profound changes in various
spheres of our society. Among these improvements, the Internet of Things (IoT) stands out as …

Byzantine fault tolerant (BFT) consensus allows the construction of robust, distributed
systems via the state-machine replication (SMR) approach. Still, after more than 40 years of …

We present TRAIL: an algorithm that uses a novel consensus procedure to tolerate failed or
malicious shards within a blockchain-based cryptocurrency. Our algorithm takes a new …

Byzantine fault-tolerance is arguably an expensive characteristic for protocols to support,
especially when considering its overhead on message complexity, number of …
