your sixth sense is right... is just noise. What other reason would they have to make such conversation in public if not to confuse plebs with a shitshow? there's probably a reason for it...

I agree though, it is good topic to increase conversation and engagement here in SN

# Minor protocol change that could reduce CTLV delta from many hours to almost nothing

[^1] CTLV delta is many hours regardless of payment size, is that correct? This is a severe attack vector for "reserve payment attack". It can be trivially shrunk to almost zero. To achieve this, the 2-phase commit needs to be improved and advanced to a 3-phase commit, and the penalty made gradual (X amount at timeout and then continuous timeouts rather than the full payment at timeout). To achieve this, a penalty must exist on every phase (which in 2-phase it does not, there is none on "prepare" step) as the cumulative timeout gets very long. To achieve this, the other 2-phase (finish-on-timeout) has to be added first and then the cancel-on-timeout (the one Lightning Network uses) afterwards, with an intermediary phase that switches the timeout behavior. I have implemented this in full. It is quite easy. I would be happy to discuss it openly, here for example. The hours long CTLV delta (regardless of payment size...) is the elephant in the room. It has been ignored as no better solution was known. There is now a better solution with the 3-phase commit. Edit: For complete implementation (trust-backed) see [here](https://resilience.me/resilience.c) (it demonstrates how to add 3-phase, and it is trivial to add 3-phase to Lightning Network), for a pretty good article see [here](https://resilience.me/3phase.pdf) and for a video presentation see [here](https://resilience.me/3phase.mp4) below.

# Tread Carefully, Build Confidently
Operating a Lightning node remotely can be incredibly rewarding — but only if approached with the same seriousness you’d apply to running a financial service. Because in many ways, that’s exactly what it is. The Lightning Network is still growing and maturing. While its promise of instant, low-cost, global payments is very real, the infrastructure behind it is still nascent. 

If you’re setting up a node just to pay over Lightning or receive some sats, modern wallets and platforms make that easier than ever. For users in this category, most of the headaches described in this article won’t apply.

But if you’re trying to run a profitable routing node — or even just a performant one — you need to treat uptime, liquidity, security, and observability as nonnegotiables. There are no shortcuts. It’s not set-it-and-forget-it. It’s a living system that demands your attention.

For those who do invest the time and care to do it right, however, the rewards go far beyond routing fees. You gain a front-row seat to the future of Bitcoin — and help shape it.
