# Worldcoin (WLD) Quantum Readiness Report

> Worldcoin has a QRI score of 2/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence.

Evaluation date: 2026-06-06. Review status: draft. Evaluated scope: WLD as ERC-20 token on Ethereum L1 and World Chain L2; includes World ID proof-of-personhood protocol. Token inherits host-chain quantum risk per QRI Section 7.2. AMPC biometric privacy layer scored separately as off-chain infrastructure..

Worldcoin (WLD) scores 2/100 on the QRI, placing it at Stage 1 (Quantum Risk Assessed). The project has acknowledged quantum risk through its AMPC biometric privacy system (quantum-secure SMPC for off-chain iris code protection) and through inheritance of Optimism's January 2026 Superchain PQ roadmap targeting ECDSA deprecation by 2036. However, all production blockchain layers — spend authorization (ECDSA/secp256k1), World ID zero-knowledge proofs (Groth16 zkSNARKs on BN254 pairing-based curve), consensus authentication (sequencer ECDSA keys), and account/public-key exposure (Ethereum EOAs) — remain fully quantum-vulnerable with no migration path active or imminent. The AMPC system provides genuine quantum-secure multi-party computation for biometric data privacy but does not protect on-chain assets, identity proofs, or consensus. No PQ code, testnet, or mainnet support exists for any blockchain layer. The WLD token inherits the quantum risk profile of Ethereum L1 and World Chain L2. The low Factor Score reflects minimal credit for having public cryptographic documentation (Least Authority audits, open-source code, protocol specs) and an ecosystem-level roadmap (Optimism 2036), but no Worldcoin-specific quantum assessment, no deployed PQ protection, and zero migration coverage.
