Google open sources their Zero-Knowledge Proof (ZKP) libraries to support age ID verification.

1. Authenticate your birth date with a trusted authority (the Issuer) and receive a cryptographically signed digital certificate.
2. A website requiring an age ID sends you a random maths puzzle.
3. The ZKP library solves the puzzle with your digital cert and replies with the proof.
4. Using the Issuers Public Cert the website validates the proof.

This is no small task, and we can't afford to be reductive in our architecture. Well worth a read. #Identity #Reputation #Social #Privacy #ZKP #Vouching
