@mullvadnet@mastodon.online So I'm trying to learn zkp right now and it seems to me that it doesn't do much.
For example, to generate a proof to verify age you need both the actual birthday and the target age. So you can't just certify a proof that can be used with any age. You have to certify ones that are for say 21 and 18 and any other you might need. So far that's what I'm seeing and that seems useless to me. You can just certify a statement that says, "This person is 18," and forego all the math.

Even if you have a zero-knowledge proof that "this person is at least 18" (without revealing their actual age) you still need to identify which person it is that the proof pertains to. That is the difficult part.
