Btw I have questions to both greenlight and economical side of LSP idea.
For greenlight, as far as I understand it outsources channel updates signing and refund destinations, but it should be able to do things like:
- publish an old channel state and let peer take all the funds (peer is greenlight).
- do nothing for long enough when peer publishes an old channel state and let them take all the funds.
If we trust them not to, this is a custodial solution.
For LSP, I would really like to know how well do current ones do and how much payment activity per channel on average do they need to be profitable.
