Researchers develop first quantum-resistant security for Bitcoin's Lightning Network

A team from East Texas A&M University and other institutions has created the first full post-quantum security solution for Bitcoin's Lightning Network. This new design layers quantum-resistant cryptography on top of Lightning's existing system, using ML-DSA and ML-KEM algorithms standardized by NIST. The hybrid approach means attackers must break both old and new cryptography to compromise transactions, protecting Lightning's off-chain payment channels from future quantum computer threats. This advance allows Lightning to prepare independently for the quantum era while Bitcoin's main network upgrades continue.

The post-quantum defense for Lightning Network is the story's subject. For readers following cryptocurrency markets, here is Pluang's market snapshot as of Oct 14, 2026 05:41 WIB: Out of 50 major cryptocurrencies, 26 rose and 23 fell today. Notable movers include CRV at Rp6.099 with a 1-day change of -3.01%, COTI at Rp223 with -2.70%, and ZIL at Rp62 with -2.66%.
