Bitcoin's Lightning Network gets first quantum-proof security layer from East Texas A&M researchers

Researchers at East Texas A&M University developed PQLN, the first working quantum-resistant security layer for Bitcoin's Lightning Network, released on September 12, 2026. PQLN adds lattice-based cryptography on top of existing protocols to protect against future quantum computer threats without replacing current systems. It operates efficiently, adding minimal delay per operation and maintaining compatibility with legacy nodes. However, it does not secure Bitcoin's base layer funds, which would require a broader network consensus to upgrade.

Bitcoin's Lightning Network quantum-proof defense is the story's subject. For readers following cryptocurrency, here is Pluang's market snapshot as of Sep 23, 2026 04:21 WIB: 34 of 50 major cryptocurrencies rose today.
