Explain why you need ZKP for their flagship problem - the “prove you’re 21” thing.

Or choose any case you like.

Explain why I can’t do it without this hilariously elementary philosophy detached from real world dev.

No cheating! I get access to the same resources. Explain why I need ZKP.

I think the fine article says it best when it says

> After doing a bit of research, we decided that the most common real world use cases of zero-knowledge proofs (age verification, crypto, etc) aren’t particularly interesting to us. We enjoyed the graphs and theory of computation and networked computing though. We hope you had fun playing around with interactive proofs too.

The inclusion of this statement makes your comments look rather bizarre and strangely combative by comparison. Maybe we can just enjoy a bit of math together?

I actually don't think ZKPs solve the age verification problem (for a variety of reasons that won't fit here), but they solve plenty of more interesting problems. Private transactions in Zcash, for example.

		Only because zcash trusts the sending node - whoever is hosting that ledger. If they had no clue who it was, like the typical http web, they could not allow a sender to be a prover, since they would not be able to verify their balance. At some point a balance inquiry would have to reveal who they are. It only works if you trust the banker. Or by being a middleman. You send [payment service] the money and they send it to the recipient, hiding your info.
