Proving knowledge without revealing information allows us to prove computations (validating them is a lot quicker than repeating the computation) and "use things" without sacrificing privacy. You can combine the two and have private transactions which are then rolled up in a computation, and then post the proof of the computation to mainnet. You get both cheap and private transactions and infra on top of the base chain.
But this goes beyond blockchain: we can hand code to other people to run and then have proof they haven't altered what we agreed upon running, so we can trust the results of someone else running something. That is useful in all sorts of research for replicability in science/engineering.
