Build a 'Zero-Knowledge Age Assurance Protocol' for decentralized platforms. Use cryptographic proofs (zk-SNARKs) to verify user age (e.g., 'User is over 16') without revealing birthdate or identity. Integrate with W3C DIDs and protocols like ActivityPub. Offer a 'Compliance SDK' for platforms to embed age gates (e.g., 'Verify age before accessing this community'). Provide audit trails for regulators.

Social platforms and decentralized networks face massive compliance costs to implement age assurance. Current solutions rely on fragile self-reporting or invasive ID verification, creating privacy risks and user friction. Non-compliance risks multi-million dollar fines under UK law. Decentralized platforms like Bluesky struggle with enforcement, as seen in Mississippi's age assurance law challenges.
