Abstract

By analyzing the states of knowledge that the processors attain in an unreliable system of a simple type, we capture some of the basic underlying structure of such systems. The analysis provides us with a better understanding of existing protocols for problems such as Byzantine agreement, generalizes them considerably, and facilitates the design of improved protocols for many related problems.
