Thanks to a fix suggested provided by Matt Corallo, I believe that this issue is now fixed and all of the Alby nodes will see that their Megalith LSP channels come back online over the next hour or so. Apologies again for the disruption, but you can remember you were around for an actual discovery of a potential problem in Lightning that had never been discovered before....
Discussion
not a fan of taproot assets, so i force closed
wouldn't have known that if you had tested updating your node without ensuring it wasn't gonna cause interop problems
i'm glad i know, i don't want to be part of funding lightning shitcoinery, sorry, not sorry
What was the issue that was fixed exactly?
We discovered a vulnerability in the interaction of two different Lightning implementations. It creates a situation close to DOS (denial of service), so we're not publicly disclosing how it works -- if we did, we could enable a bad actor to attempt to bring down other services. But the implementations involved are both aware of the situation and will be patching it in an upcoming release. We also remediated the situation on our end so we're no longer vulnerable.
Wow! Amazing work
