Webtitle = {Reaching Agreement in the Presence of Faults}, year = {1980}, month = {April}, This paper shows that "Byzantine" faults, in which a faulty processor sends inconsistent information to the other processors, can defeat any traditional three-processor algorithm. (The term Byzantine didn't appear until [46].) WebAlgorithms are presented to reach approximate agreement in aynchronous, as well as synchornous systems. The asynchronous agreement algorithm is an interesting contrast to a result of Fischer, Lynch, and Paterson, who show that exact agreement is not attainable in an asychronous system with as few as one fault process. The algorithms work by ... grant writing consultant fee
