WebComputer Science. Computer Science questions and answers. Show that if binary consensus using atomic registers is impossible for two threads, then it is also impossible for n threads, where n > 2. (Hint: argue by reduction: if we had a protocol to solve binary consensus for n threads, then we can transform it into a two-thread protocol.) 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. A consensus protocol is an algorithm that produces such an agreement. Each process in a consensus protocol has, as

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.
