As 6G communication technology advances, there is a growing trend of incorporating
blockchain technology, which has already demonstrated its effectiveness in multiple areas …

The Narwhal system is a state-of-the-art Byzantine fault-tolerant scalable architecture that
involves constructing a directed acyclic graph (DAG) of messages among a set of validators …

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 …

Abstract State Machine Replication (SMR) solutions often divide time into rounds, with a
designated leader driving decisions in each round. Progress is guaranteed once all correct …

The problem of distributed consensus has played a major role in the development of
distributed data management systems. This includes the development of distributed atomic …

The Dolev-Reischuk bound says that any deterministic Byzantine consensus protocol has
(at least) quadratic communication complexity in the worst case. While it has been shown …

It is a common belief that Byzantine fault-tolerant solutions for consensus are significantly
slower than their crash fault-tolerant counterparts. Indeed, in PBFT, the most widely known …

Byzantine state-machine replication (SMR) ensures the consistency of replicated state in the
presence of malicious replicas and lies at the heart of the modern blockchain technology …

Modern chained Byzantine Fault Tolerant (BFT) systems leverage a combination of
pipelining and leader rotation to obtain both efficiency and fairness. These protocols …

First-generation blockchains provide probabilistic finality: a block can be revoked, albeit the
probability decreases as the block sinks deeper into the chain. Recent proposals revisited …
