Post-Quantum Qoin

Consensus: Quantum-Vulnerable
Why this rating. Judgment call: default block validation requires multivariate proof of work and Drand beacons authenticated with classical BLS signatures. The Dilithium or Falcon block-signature check is commented out in core/consensus/qoincns/qcoin.go.
Transactions: Quantum-Vulnerable
Why this rating. Judgment call: MultiPqcVerify in lib/sigs/sigs.go verifies signatures against keys supplied with them, without binding those keys to the sender. An empty key list also succeeds. The secp256k1 path checks the sender address.
Algorithms: None listed
Website: Website
Source: Source
Note and links: PQ checks unbound to sender
