Editorial v1. Scores are derived from public design documents, NIST PQC literature (ML-KEM / ML-DSA / SLH-DSA), and project disclosures as of June 2026. Adoption and security weights are conservative; lower confidence means we have less independent evidence. Disagree with a score? Email support@quantumcryptorisk.com with sources.

FAQ

Frequently asked questions

How are the quantum crypto rankings calculated?

Every project is scored on six pillars — security, transparency, adoption, developer activity, decentralization, and usability — with explicit public weights. Confidence labels reflect how much independent evidence supports each score. Full methodology is published at /methodology.

Why does Bitcoin not rank as quantum-safe?

Bitcoin currently relies on ECDSA over secp256k1, which is vulnerable in principle to a large quantum computer running Shor's algorithm. No mainnet Bitcoin address type uses NIST PQC signatures today. Ongoing BIP discussions (e.g., quantum-resistant address types) are tracked in the score as pending, not delivered.

Do any live blockchains actually use NIST PQC?

As of 2026, no top-cap public blockchain has migrated its consensus signatures to ML-DSA or SLH-DSA. Some newer projects use post-quantum-adjacent primitives (hash-based signatures, lattice hybrids) but none are drop-in replacements for existing UTXO or account-based chains. The rankings flag this clearly.

Can I dispute a score?

Yes. Send sources to support@quantumcryptorisk.com. Every ranking includes a change log, and confidence labels are downgraded when new evidence contradicts the current score.
