Build 'PrivacyShield AI'—a $25K/year SaaS platform that provides privacy-preserving age verification for decentralized platforms using zero-knowledge proofs (ZKPs) and federated identity. The platform would: 1) Deploy ZKPs to verify user ages without collecting PII (e.g., 'User is 18+—verified by state DMV without revealing DOB'); 2) Provide a 'Compliance Dashboard' showing real-time verification rates (e.g., 'Mississippi compliance: 95%—no blocked users'); 3) Integrate with state DMV APIs and passport databases via federated queries (e.g., 'Query Texas DMV—no data stored'); 4) Offer a 'State Risk Score' showing legal exposure (e.g., 'Florida: High risk—new law pending').
