Know Your Address - Proving Humanity Onchain
summary
Provable builds a working stack: ZPass issues verifiable credentials that produce ZK proofs for concrete claims like “over 18,” “resident of X,” or “not on a sanctions list” without revealing raw IDs; passport registration verifies government signatures and can anchor a record onchain. KYA uses on‑device ZKML facial verification (enroll three samples, train a model in ~20 seconds) to prove ongoing control of an address; demo at kya.provable.com runs on mobile/desktop and does not store raw biometrics.
