Reaching agreement in the presence of faults
WebJul 27, 1995 · We study in these models the classical testbed problem for fault tolerant distributed computing: Byzantine agreement. It has been shown that if ρ=1, then agreement cannot be reached in the... WebByzantine Agreement, Quantum Computation 1. INTRODUCTION Reaching agreement in the presence of faults is a funda-mental problem in distributed computation. Here a group of n players must agree on a bit despite the faulty be-havior of some of the players. Ruling out trivial solution (such as always deciding on the same bit), this problem,

WebJan 1, 1994 · Faulty processes mayattempt to inhibit agreement by acting in a malicious or "Byzantine" manner. Approximate agreement defines one form of agreement in which the voted values obtained by the non-faulty processes need not be identical. Instead, they need only agree to within a predefined tolerance. WebPease, Marshall, Robert Shostak, and Leslie Lamport. “Reaching agreement in the presence of faults.” 27.2 (1980): 228-234.
