Unknowable Math Can Help Hide Secrets

Is the approach analogous to one way hash? But with mathematical statements?

Given that they can’t be proven, so it’s effectively unpredictable and “un-generatable” ?

How is this not security through obscurity?

What is that new powerful tool in cryptography, then?

I'm not sure what "interactive" means here, but I thought ZK-SNARKs were already non-interactive.

It seems the article has nothing to do with anything practical..
