Accepts both post-quantum (mars1z…) and legacy (M…) addresses.

Generate a brand-new quantum-resistant address on the node. Save the address and pubkey — they are not stored anywhere else.

What makes this quantum-resistant?

🔐 SPHINCS+ / SLH-DSA

These mars1z… witness v2 outputs are protected by SPHINCS+ (standardized as SLH-DSA by NIST in FIPS 205). It uses only SHA-256 hash trees — no elliptic curves, no RSA, no discrete logarithms.

⚡ Why it matters

A sufficiently large quantum computer running Shor's algorithm can break ECDSA (used by Bitcoin/Marscoin) in polynomial time. Hash-based signatures like SLH-DSA remain secure even against quantum adversaries.

📦 Witness v2 outputs

  • Script type: witness_v2_pq
  • Spending requires a valid SLH-DSA signature
  • ~8 KB signature size (trade-off for security)
  • Native SegWit — no wrapping needed
