Self Protocol Workshop
summary
A decentralized identity system that registers passports, Aadhaar or biometric IDs into an onchain Merkle tree to produce a unique nullifier and prevent duplicate sign‑ups, then uses Groth16 + Circom ZK proofs (generated in TEEs because some zkeys are ~5GB) to disclose single attributes via a QR flow and SDK. Example contract extends SelfVerificationRoot, verifies proofs on chain, emits events; hackathon bounties prioritize onchain work up to $5,000.
