Quantum Cryptography vs Post-Quantum Cryptography: Claim Check
“Quantum security” can describe several different operations. This reference classifies a claim by the equipment it needs and the result it produces, then identifies the evidence needed before extending that claim to a cryptocurrency.
Which details distinguish a QKD claim from a PQC claim?
Ask what the system uses and what it produces. A QKD claim describes quantum signals and equipment used to establish shared key material. A post-quantum KEM describes an algorithmic shared-secret operation. A post-quantum signature describes signing and verification with public and private keys. These operational details are more informative than a product’s use of the word “quantum.”

NIST’s quantum cryptography overview identifies QKD as one example within a broader field. The table classifies these common claims; it does not treat QKD as the whole of quantum cryptography.
| Claim describes | Classification and source | Evidence to request next |
|---|---|---|
| Quantum signals and a resulting shared key | QKD is a quantum-cryptography example. NIST overview | Protocol, equipment, endpoint authentication and covered link. |
| Encapsulation and decapsulation of shared secret material | Post-quantum KEM, if the named scheme is PQC. ML-KEM standard | Exact algorithm, parameters and surrounding authenticated protocol. |
| A signature checked against a public key | Digital-signature operation; identify the specific scheme. ML-DSA standard | Signed data, key format, verification rules and deployed implementation. |
| SLH-DSA or a SPHINCS+ family label | Hash-based signature claim with names that need precise source identification. SLH-DSA standard | Exact algorithm name, parameter set, version and any conformance evidence. |

When does a claim provide evidence about blockchain authorization?
A claim concerns blockchain authorization when it identifies the signed transaction data and the verification rules that the network enforces. Evidence about a protected communication link or established shared secret addresses another operation. To connect either claim to spending security, request the actual authorization scheme, its parameters and its deployed verifier rather than inferring them from the channel technology.

The distinction follows the separate operations specified by FIPS 203 和 FIPS 204. Our classification applies that distinction to the scope of a cryptocurrency claim; it does not evaluate any particular QKD product.
SYNX claim scope
As reviewed September 21, 2026, the SYNX whitepaper states: “SynX uses SPHINCS+-SHAKE-128s” and “SynX uses Kyber-768”. The signature and key-encapsulation roles are project claims. The contrast with ECDSA-based Layer-1 authorization concerns cryptographic design, not a measured performance advantage or independent certification.

Which cryptographic role fits your task?
Choose the operation to see the relevant role and its primary source. This selector classifies functions; it does not certify a coin or implementation.
All cryptographic roles are shown below.
按鍵封裝
ML-KEM establishes shared key material; the application uses that material within a complete encryption protocol. See FIPS 203 和 how key establishment differs from blockchain authorization.
數位簽名
A verifier checks signed data against a public key. ML-DSA 和 SLH-DSA are NIST signature standards. See how signature families change a Layer-1 integration.
Quantum key distribution
QKD uses quantum signals to establish key material across a suitable link. See NIST’s quantum-cryptography explanation 和 how QKD differs from software PQC roles.
Stateful signature management
XMSS and LMS are stateful hash-based signature schemes; their state requirements belong in the implementation and recovery design. See NIST SP 800-208 和 how signature state changes backup requirements.
