ZKPassport is a privacy-preserving digital identity protocol that enables users to verify attributes such as age, nationality, and humanity using zero-knowledge proofs without exposing personal data. By scanning NFC-enabled passports or IDs locally on a device, users can generate cryptographic proofs that applications can verify without storing sensitive information. The protocol is designed for compliance, Sybil resistance, access control, and Web3 onboarding while maintaining user privacy and self-custody of identity data.
