Apparently we may have a good solution to the Lightning Replacement Cycling Attack: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2023-October/022040.html
Uff 😓 👍
"This attack isn't easy. Pulling it off involves:
- opening two channels with the victim.
- routing a payment through them.
- successfully replacement-cycling the victim's htlc-timeouts for Δ blocks.
- without the victim discovering the htlc-preimage transaction.
Despite that, the attack is also hard to solve completely, explained @mononaut in a thread.
@niftynei also held X Spaces explaining the vulnerability."
What's the best eli5 for the attack and maybe also for the solution if there is one?
My bad, the original link has a pretty good explanation. I only saw the top comment on my feed.

Still refuse to go on X 😂
I'm not LN advanced, but imma repost it's important. Can't have bugs brooo
My understanding of it is that the bug isn't that of lightning, but a "feature" of the layer 1 and any layer 2 will be susceptible to it.
Any YouTube videos I like audio 😅
Idk about YouTube, but I'll go back and see if I can figure out which podcast I listened to that talked about it. I feel like it was rabbit hole recap #275 but I'm not at all certain.
