Researchers Build First Working Post-Quantum Defense for Bitcoin Lightning Network
- —Implementation runs on Rust-Lightning with about 11,000 lines of code
- —Hybrid scheme pairs ML-DSA signatures with ML-KEM key encapsulation
- —Defense works without waiting for a base-layer Bitcoin upgrade
- —Large post-quantum key sizes remain the main deployment hurdle
Why it matters: Lightning can harden its channels and payments against quantum attacks before Bitcoin's base layer upgrades its signature scheme.
