Somebody could be recording Lightning traffic right now, betting a future quantum computer will crack it open. A team from East Texas A&M and three other universities just built PQLN to guard against that, a post quantum layer for Lightning's gossip, connections, invoices, and payment onions. It runs on rust lightning next to normal nodes and adds at most a third of a millisecond.

It's a preprint, channel funds still wait on Bitcoin itself, and gossip gets heavier. But somebody built it and tested it on real nodes. Read it and make it better.
