## Description

Join Marek Olszewski at Pragma Denver 2025 as he unveils Self Protocol, a new identity and verification solution leveraging machine-readable biometric passports, zero-knowledge proofs, and Celo’s emerging Layer-2 architecture.

Learn how Self Protocol addresses critical crypto challenges—like Sybil resistance, verifying you’re not on an OFAC list, and even confirming you’re human—without exposing private data. Marek demonstrates the mobile onboarding experience, explains the trusted execution environment (TEE) for secure proofs, and shows how developers can integrate Self Protocol’s SDK for dApps requiring age checks, region blocks, or other identity-based logic.

If you’re searching for privacy-preserving identity solutions in Web3, this talk has you covered.
