Consensus: Quantum-Vulnerable
Why this rating. Judgment call: subnet consensus runs on threshold BLS signatures (ICP docs). DFINITY describes crypto agility and monitoring, per a forum summary, but publishes no post-quantum code, plan or timeline.
Transactions: Quantum-Vulnerable
Why this rating. The interface specification allows Ed25519, ECDSA P-256 and secp256k1 signatures only. The dfinity/ic repository holds no post-quantum signature code, and no roadmap item or proposal was found.
Algorithms: None listed
