Build 'ZKAge'—a zero-knowledge proof (ZKP) based age verification protocol for decentralized platforms. The platform would: 1) Use cryptographic proofs to verify user age (e.g., 'User is over 18') without revealing birthdate or identity; 2) Integrate with decentralized identity standards (e.g., W3C DIDs, SpruceID) for seamless adoption; 3) Offer a 'compliance SDK' for platforms to embed age gates (e.g., 'Verify age before accessing this Bluesky community'); 4) Provide audit trails for regulators. Monetization via per-verification fees ($0.50/user), enterprise SaaS ($50K/year), and white-label solutions for governments.

Decentralized social networks (e.g., Bluesky, Mastodon), healthcare platforms, and regulated industries (e.g., telemedicine, fintech)
