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.

Thanks Nick, I'd completely forgotten about nitter!
