World Opens ProveKit to Developers for Privacy-Preserving Age Checks

This is a strategic expansion beyond World's own identity ecosystem, signaling a bet that privacy-preserving verification becomes a standard middleware layer for apps. The significance lies in shifting from a proprietary identity solution to an infrastructure play, which could accelerate adoption of zero-knowledge proofs in mainstream consumer contexts if developers see demand for age gates without document exposure. It affects both app developers seeking compliant verification and users wary of data leakage. The open question is whether third-party integration gains traction beyond crypto-native use cases, or if regulatory and trust hurdles keep it niche.
