World Unveils Quantum-Resistant Zero-Knowledge Proving Toolkit

World has unveiled an open-source and production-ready zero-knowledge (ZK) proving toolkit called Provekit v1. This toolkit allows users to generate cryptographic proofs directly on smartphones and web browsers without revealing sensitive data to third parties.

The toolkit is already integrated into World ID, a system for verifying human identity. The goal of the toolkit is to enable AI agents to prove they are backed by a unique and verified person through World ID. Provekit v1 relies on a hash-based commitment scheme called WHIR instead of traditional elliptic-curve math.

This allows smartphones running the World App to handle computations without holding large proving keys in memory, making it possible for low-end devices to use the system. Benchmark tests show that Provekit generates proofs in just a few seconds on standard smartphones and under 30 seconds on low-end hardware.

According to a spokesperson for the World Foundation, post-quantum security is necessary because migrating to quantum-resistant standards takes years to execute, even though practical quantum attacks may be five to 15 years away. The toolkit processes zero-knowledge proofs locally rather than transmitting raw biometrics or credentials over the web.

Developers can create custom claims using Noir, an open-source domain-specific language developed by Aztec. World is currently developing Provekit v2, which aims to further reduce proof sizes and memory consumption while improving on-chain verification efficiency.
