WebReaching agreement in the presence of faults has been a cornerstone of distributed computing for over 40 years. In this paper we consider the asynchronous model with an adaptive adversary, where the adversary is allowed to delay any message between any two parties by any finite amount and can choose the delay and who to corrupt WebAlgorithms are presented to reach approximate agreement in asynchronous, as well as synchronous systems. The asynchronous agreement algorithm is an interesting contrast to a result of Fischer, Lynch, and Paterson, who show that exact agreement is not attainable in an asynchronous system with as few as one fault process.
