The paper considers the consensus problem in a partially synchronous system with Byzantine processes. In this context, the literature distinguishes (1) authenticated Byzantine faults, where messages can be signed by the sending process (with the assumption ...
The paper proposes a generic consensus algorithm that highlights the basic and common features of known consensus algorithms. The parameters of the generic algorithm encapsulate the core differences between various consensus algorithms, including leader-ba ...

The paper considers the consensus problem in a partially synchronous system with Byzantine faults. All deterministic algorithms that solve consensus in this context are leader-based. However, in the context of Byzantine faults, leader-based algorithms are ...
Problems in fault-tolerant distributed computing have been studied in a variety of models. These models are structured around two central ideas: (1) degree of synchrony and failure model are two independent parameters that determine a particular type of sy ...
In modern distributed systems, failures are the norm rather than the exception. In many cases, these failures are not benign. Settings such as the Internet might incur malicious (also called Byzantine or arbitrary) behavior and asynchrony. As a result, and ...

The perfectly-synchronized round-based model provides the powerful abstraction of crash-stop failures with atomic and synchronous message delivery. This abstraction makes distributed programming very easy.We describe a technique to automatically transform ...
The Byzantine failure model allows arbitrary behavior of a certain fraction of network nodes in a distributed system. It was introduced to model and analyse the effects of very severe hardware faults in aircraft control systems. Lately, the Byzantine failu ...
