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.
