Researchers Build First Working Post-Quantum Defense for Bitcoin's Lightning Network

  • —The design uses ML-DSA and ML-KEM, post-quantum algorithms standardized by NIST
  • —New quantum-resistant cryptography is layered on top of Lightning's existing cryptography rather than replacing it
  • —The implementation took three to four months and about 11,000 lines of code in Rust-Lightning
  • —An attacker would have to break both the new and the old cryptography to compromise a connection
Why it matters: The work shows Lightning's off-chain systems can prepare for the quantum era independently while others focus on mainnet solutions.
