# Canton Network (CC) Quantum Readiness Report

> Canton Network has a QRI score of 12/100 and is assessed at Stage 2 (Mitigation / Development) with medium evidence confidence.

Evaluation date: 2026-06-01. Review status: draft. Evaluated scope: Native asset (CC), base-layer protocol cryptography, privacy layer, EVM integration, and institutional transaction authorization.

Canton Network has a public, detailed cryptographic inventory, a published risk assessment (DA forum, April 2025), and active mitigation design work in progress (Quanton proposal for native PQC verification, BOLTS QFlex pilot, FC 2026 research paper on key migration). However, zero production protection exists across all critical layers: spend authorization, consensus authentication, privacy encryption, P2P transport, node identity, and wallets remain entirely classical (Ed25519, ECDSA, RSA). All ~$6B market cap (~$4T+ institutional assets) is quantum-vulnerable with no migration path deployed. The project's privacy model advantageously avoids quantum-vulnerable ZK proof systems but encryption remains classically dependent and vulnerable to store-now-decrypt-later. The QRI Score of 12 (Stage 2: Mitigation / Development, capped at 40) reflects a project that has acknowledged risk and initiated design work but has not yet materially protected production users.
