ZKPassport Case Study: A Look into Online Identity Verification | Aztec Blog

Aztec explores the challenge of verifying user identity in decentralized systems while safeguarding privacy. ZKPassport addresses this by enabling users to prove they hold a valid passport or government ID through an NFC scan, without revealing any sensitive information. The underlying zero-knowledge proofs (ZKPs) are generated locally on the user's device, ensuring complete data minimization. This method enables Aztec to onboard verified human node operators onto its Testnet, increasing decentralization while defending against Sybil attacks and bot infiltration.

Key Ideas

1. ZKPassport uses ZKPs to confirm user identity without revealing private data, solving for privacy-respecting Sybil resistance in decentralized networks.

2. Local proof generation via NFC-scanned IDs empowers trusted participation, helping Aztec scale its validator set securely and with enhanced user privacy.
