Simple and efficient asynchronous byzantine agreement with optimal resilience
Consider a completely asynchronous network consisting of n parties where every two parties are connected by a private channel. An adversary At with unbounded computing power activ...

Fast Asynchronous Consensus with Optimal Resilience
Abstract. We give randomized agreement algorithms with constant expected running time in asynchronous systems subject to process failures, where up to a minority of processes may f...

Optimal Resilience Asynchronous Approximate Agreement
Consider an asynchronous system where each process begins with an arbitrary real value. Given some fixed > 0, an approximate agreement algorithm must have all non-faulty process...

An Almost-Surely Terminating Polynomial Protocol for Asynchronous Byzantine Agreement with Optimal Resilience
Consider an asynchronous system with private channels and n processes, up to t of which may be faulty. We settle a longstanding open question by providing a Byzantine agreement pr...

Signature-Free Broadcast-Based Intrusion Tolerance: Never Decide a Byzantine Value
: Provide application processes with strong agreement guarantees despite failures is a fundamental problem of fault-tolerant distributed computing. Correct processes have not to be...
