World Unveils Open-Sourced ProveKit Toolkit for Private Identity Checks
World has open-sourced ProveKit, a production-ready zero-knowledge toolkit for private ID checks. The release makes its on-device proof-generation stack available to developers, according to the World Foundation.
ProveKit is designed to let users establish specific identity-related claims without exposing underlying identity data. Proof generation takes place locally and private information does not leave the device. Instead of sending an identity document or full personal profile to a verifier, the interaction is a cryptographic assertion limited to the claim being requested.
The ProveKit repository supports compiling Noir programs into R1CS constraints and generating and verifying WHIR proofs, with integrations for Rust, JavaScript, Swift, Kotlin, and C-compatible environments. World said ProveKit combines Noir, WHIR, and Spartan-based proving, targets 128-bit post-quantum security, requires no trusted setup, and was independently audited by Least Authority.
World is already working on ProveKit v2, which will focus on reducing proof sizes and memory consumption while making on-chain verification more efficient. This version is positioned as practical constraints for client-side proving and blockchain-based verification.
