Build 'PrivacyLock'—a decentralized, on-device age verification protocol using zero-knowledge proofs (ZKPs) and federated learning. The platform would: 1) Replace ID uploads with cryptographic proofs (e.g., 'User is over 16' without revealing birthdate); 2) Integrate with decentralized identity standards (W3C DIDs, SpruceID) for seamless adoption; 3) Deploy edge AI to detect circumvention (e.g., VPNs, deepfake IDs) without storing user data; 4) Provide 'Compliance SDKs' for platforms to embed age gates (e.g., 'Verify age before accessing Bluesky/Mastodon'); 5) Offer audit trails for regulators (e.g., 'Zero violations in Q2').
