Your point about the need to "popularize" zk-snarks etc. is well-taken and I upvoted you for it.

But that said, we seem to be talking past each other at this point. I don't see why my criticism of the OP was unconstructive. This is not actually a research paper, it has not undergone any sort of academic peer review, and if the goal is to present it as one example of the kinds of things that are possible to build with zkSNARKs, then it ought to be presented in that context.

I do want to note that it is possible to compose zkSNARKs in an application in ways that result in the composition not being zero-knowledge. Not saying that has happened here, but implying there's no danger with incorrect usage of zkSNARKs seems sketchy to me.
