How far away are we from a simple ZK passport implementation?

Would let Farcaster users verify an email or passport without disclosing sensitive information. 

Key word is simple (i.e, can build a working FC prototype in a day).

2 projects I’m aware focused on this are:

ZKPassport - https://zkpassport.id/
Self Protocol - https://docs.self.xyz/

I’ll also add that regardless if you use one or build your own, I would suggest a Noir implementation. Compiled circuits are smaller file size and shaves off proving time if paired with UltraHonk.
