All the "solutions" I've seen don't prove anything to anyone until after the "proof" recipient has found Waldo - this may have been acceptable by the intent of the original author of the problem, but it's sure not how I read the wording.So, we need to come up with a way to present information to the competition that proves (when read), that we know the answer, without giving away the answer?It doesn't necessarily need to be just a one-way transfer of a single blob of information; it could be interactive (as most - all? - zero-knowledge proofs are).
Yeah - I should have written "(when presented)" instead of "(when read)".
