Qubitcoin

Consensus
No Signatures / Quantum Resistant

Why this rating. Bitcoin Core fork with qPoW proof of work (SHA-256 plus quantum circuit simulation); blocks need no validator signatures.

Transactions
Quantum-Vulnerable

Why this rating. Judgment call: Bitcoin Core fork keeping secp256k1 keys. No post-quantum code in the repository; the website only says it plans quantum-resistant infrastructure, with no design or timeline, so we chose the less ready value.
