Acinq LSP is used for trampoline routing. Phoenix to Phoenix, acinq knows exactly who's paying whom how much. They can follow every single payment
Super sounds like cope af

I figured out a way to let any lightning wallet route a payment even if it doesn't have code for routing. The technique has a few things in common with the concept of "wrapped invoices" except I figured out how to do it even if the wallet doesn't have code for creating them.
I also figured out how to use this technique to ruin the heuristics Acinq uses to determine the "origin" phoenix wallet and the "recipient" phoenix wallet. I know how to blind an LSP.
Wanna help me build it? I'm happy to discuss it with you in DMs!
Sounds fun. I was talking about the current implementation which doesn't use wrapping or anything like that. The server literally knows every payment you make, sometimes on both ends.
