WebFeb 22, 2005 · Byzantine Agreement (BA) is a paradigm problem that attempts to isolate the key features of reaching agreement. We focus here on the number of messages required to reach BA, with particular emphasis on the number of messages required in the failure-free runs, since these are the ones that occur most often in practice. WebThe simplest good algorithm for Byzantine Agreement with reliability t is optimal with respect to time for immediate agreement (t+l phases). Though its0(n2)message requirement is not optimal, we discuss it here because it establishes the feasibility of actually implementing algorithms for Byzantine Agreement with reliability greater than 1.
