In computer science, Uniform Consensus is a distributed computing problem that is a similar to the consensus problem with one more condition which is no two processes (whether faulty or not) decide differently.
More specifically one should consider this problem:
- Each process has an input, should on decide an output (one-shot problem)
- Uniform Agreement: every two decisions are the same
- Validity: every decision is an input of one of the processes
- Termination: eventually all correct processes decide
- Uniform consensus is harder than consensus (Bernadette Charron-Bost and André Schiper)
