Varying models of computation may define a "consensus problem". Some models may deal with fully connected graphs, while others may deal with rings and trees. In some models message authentication is allowed, whereas in others processes are completely anonymous. Shared memory models in which processes communicate by accessing objects in shared memory are also an important area of research. Webof randomized asynchronous consensus protocols by giving detailed de-scriptions of several such protocols. 1 Introduction The consensus problem [45] is to get a group of nprocesses in a distributed system to agree on a value.
