Abstract
A method for achieving agreement among n participating network devices to an agree-value in a network is disclosed. The method proposes an optimistic approach to the consensus problem, whereby the number t of faulty devices is less than n/3. It is distinguished between an optimistic and pessimistic case. In the pessimistic case, a fallback agreement protocol is performed that reaches the same agree-value as the method in the optimistic case outputs.
