## Description

Learn how to build privacy-preserving identity verification with Self Protocol in this ETHGlobal Taipei 2025 workshop. Discover how biometric passports and zero-knowledge proofs (ZKPs) enable applications to verify user attributes (age, nationality, sanctions compliance) without exposing personal data.

The Self team demonstrates on-chain and off-chain integration of their SDK, including QR code flows for mobile verification and smart contract templates for attestations. With $10K in hackathon prizes for innovative implementations, this workshop covers everything from passport NFC scanning to ZK proof verification on Celo. Ideal for developers building compliant DeFi, airdrops, or age-gated dApps with real-world identity solutions.
