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 decide on 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
