Bolt12 does nothing for privacy, blinded paths maybe do (debatable) but exist outside of Bolt12 (LND has had them for a long time already) CLINK is better for static addresses, and more private since it's decoupled from the node, allows for HA, and is out of band on a web port. (static addresses are a misnomer because Lighting is inherently synchronous, they're just pointers to a live endpoint) Bolt12 is literally just invoice passing over Tor-like onion messages, fortunately LND has an option to disable them. Since you can't inspect them you can't block non-invoice data, Bolt12 is a vulnerability pushed by the minor implementations who went all in on phones-are-servers. Dumbest thing ever.

Onion routed payments mean that routing nodes can't collect telemetry on the payment details. Surely that's a privacy improvement. #Utreexo moves us a long way toward phones and other low cost devices become lightning nodes. There are some sub $60 options at waveshare.com

In CLINK how do you preserve network privacy when your node is interacting with nostr relays?
