World is releasing ProveKit, its zero-knowledge proof toolkit, to let any app verify age, nationality, or ID status without storing personal data. The move trades World's competitive moat for infrastructure control, positioning the company as the plumbing layer for privacy-preserving identity rather than a direct consumer play, while normalizing orb-based biometric collection as the trust foundation for digital identity at scale. The leverage sits in the iris-scan dataset World has already accumulated and the network effects of apps built on verified identity proofs.
