Isn't it enough no show a hash?
- JanisErdmanis 4y agoIt would be a random string for the verifier as he does not know the secret. It’s much like one can sign a document without revealing a secret key. In fact signatures are proofs of g^sk=pk where the document hash is a verifier challenge.
- Double_a_92 4y agoA hash of what exactly though? This would only work as a timestamp, if you ever plan to publicly release your secret. But it wouldn't work if you e.g. want to find other people that also know what you know, without ever telling anyone. (Because they wouldn't have your exact text or document to hash...)
