Build 'AgeChain'—a blockchain-based, privacy-preserving age verification protocol for decentralized social networks. The platform would: 1) Use zero-knowledge proofs (ZKPs) to verify age without storing personal data; 2) Integrate with decentralized identity standards (W3C DIDs, SpruceID) for seamless adoption; 3) Provide 'Age Verification Nodes' that platforms can deploy to comply with regulations; 4) Offer a 'Regulatory Compliance Dashboard' showing audit trails for regulators; 5) Auto-generate 'Child Safety Certificates' for platforms to display compliance (e.g., 'AgeChain Verified: 99.9% accuracy').

Market Catalyst & News Trigger

"Pinterest CEO calls on governments to ban social media for users under 16, comparing it to tobacco and alcohol protections."

The Workflow Friction

Governments are under pressure to regulate social media for minors, but decentralized platforms (e.g., Bluesky, Mastodon) lack scalable age verification tools. Current solutions (e.g., ID uploads) violate user privacy and are easily circumvented. The friction includes: 1) Legal risks for platforms (fines, bans); 2) Operational costs of manual verification; 3) User attrition due to invasive methods; 4) Lack of interoperability across decentralized networks.
