In existing asynchronous distributed systems it is impossible to implement failure detectors which are perfect, i.e. they only suspect crashed processes and eventually suspect all...
We consider a set of clients collaborating through an online service provider that is subject to attacks, and hence y trusted by the clients. We introduce the abstraction of a fai...
Failure detectors — oracles that provide information about process crashes — are an important ion for crash tolerance in distributed systems. Although current failure-detector...

Abstract. We argue that failure detectors encapsulate fairness. Fairness is a measure of the number of steps a process takes relative to another processes and/or messages in transi...
We present a consensus algorithm that combines unreliable failure detection and randomization, two well-known techniques for solving consensus in asynchronous systems with crash f...
