This has nothing to do with zero-knowledge crypto. Here's some intuition about what zero-knowledge is actually about: https://minaprotocol.com/blog/kimchi-the-l

  It's my understanding that zero-knowledge concepts can be extended to databases, in a way where I can query a database and get a result without knowing the contents, perhaps to pass on to a trusted system to perform another action. Depending how you slice it, I either do or don't get to know if the result set is empty. In the latter case, there's a variation of this crush registration system where I don't get to know if Sally has a crush on me, but I do find out if anyone has a crush on me. Of course if the answer is empty set, I don't know if I'm unloved or only loved by people that don't use the app. Which could be pretty heavy.

    This system is not zero knowledge, because publishing the link actually leaks info to non-intended recipients. Suppose I share a link, and you suspect I am trying to steal your partner. You could easily check whether my crush is your partner.

    What you’re describing is more like MPC to me

  Crypto like cryptography or crypto like cryptocurrency?

    Aren't they the same? Cryptocurrency is called that because it uses cryptography.

    As in cryptography, although the link I posted also explains how it can be applied to smart contracts
