SPHINCS+ vs Dilithium for a Layer-1 blockchain
A Layer-1 signature choice affects transaction encoding, verification and wallet support. Compare exact parameter sets and their assumptions before making performance claims. Dilithium led to ML-DSA; SPHINCS+ is the basis of SLH-DSA.
What changes when a blockchain chooses SPHINCS+ instead of Dilithium?
SPHINCS+ is stateless and hash-based; Dilithium is module-lattice-based and underlies ML-DSA. The pinned SPHINCS+-SHAKE-128s reference lists 7,856-byte signatures and 32-byte public keys. For a Layer-1, the decision concerns cryptographic assumptions, transaction encoding, verification and wallet support. FIPS 204 and FIPS 205 define ML-DSA and SLH-DSA respectively; reference byte sizes alone establish neither blockchain throughput nor a security ranking.

FIPS 204 specifies ML-DSA; FIPS 205 specifies SLH-DSA based on SPHINCS+. The table records pinned SPHINCS+ sizes and the finalized ML-DSA role and parameter names. It is not a runtime or matched-security benchmark. Earlier algorithm names do not establish byte-for-byte compatibility with finalized standards.
| Reference | Security basis | Parameter scope | Public evidence used here | Layer-1 check |
|---|---|---|---|---|
| Pinned SPHINCS+-SHAKE-128s | Stateless hash-based | The 128s variant | 7,856-byte signature; 32-byte public key; 64-byte secret key. | Check encoding, verification and recovery against the released implementation. |
| ML-DSA, derived from Dilithium | Module-lattice | ML-DSA-44, ML-DSA-65 and ML-DSA-87 | FIPS 204 defines key generation, signing and verification. | Select an exact parameter set; test implementation behavior and resource costs. |

What does SYNX publicly specify, and what still needs measurement?
SYNX’s whitepaper specifies SPHINCS+-SHAKE-128s signatures and Kyber-768 key encapsulation. The pinned SPHINCS+ reference supplies raw parameter sizes, not SYNX release measurements. Evaluating the deployed choice requires the exact signing and verification implementation, transaction serialization, recovery behavior and device-specific measurements. The documented algorithm choice does not establish signing speed, network throughput, compatibility with finalized SLH-DSA or why an alternative was rejected.

The live SYNX whitepaper identifies the design; it does not supply benchmark logs for this comparison. The pinned upstream SPHINCS+ table supplies raw sizes. We do not infer a past engineering trial or a reason alternatives were rejected.
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.
