Bitcoin may go quantum-safe while Lightning privacy stays exposed

Even if Bitcoin eventually adopts post-quantum protections for on-chain outputs, five parts of the Lightning Network’s off-chain payment system would still need separate upgrades, according to a Sept. 12 research preprint.
Key facts
- By contrast, ML-DSA-44 signing averaged 327 microseconds on the authors’ 16-core AMD Ryzen Threadripper PRO 3955WX workstation with 64 GB of RAM
- Bitcoin is +0.96% over the past 24 hours and currently sits at rank # 1 by market cap
- It adds hybrid ML-KEM key exchange to transport, payment onions and BOLT 12 privacy paths
- A smaller Falcon-derived FN-DSA configuration reduced the download multiple to 4.2 times, but NIST still lists that scheme as under development rather than a final standard
Summary
02 Default ML-DSA and ML-KEM settings raised full gossip downloads 10.2-fold. The paper proposes PQLN, a hybrid post-quantum extension implemented as a rust-lightning research prototype. Lightning currently uses secp256k1-based ECDSA, Schnorr signatures or ECDH across those functions. The authors built a feature-gated rust-lightning fork and a modified ldk-sample node.
