While I respect the attempt of nostr:npub1yxp7j36cfqws7yj0hkfu2mx25308u4zua6ud22zglxp98ayhh96s8c399s to present the Lightning network as financial privacy tech
I hate it when it provides reassurance to people who have no idea what they’re doing.
Tor + opening private channels won’t help your invoices hide information about your node.
Have you actually retrieved information about a node you are spending to? Or is it just something you've heard is possible?
He's probably talking about the nodes pub key.
Still, perfect is the enemy of good. So the criticism seems a little flimsy.
It does help if the user has ever had any public channels. Nodes with public channels publish a network string in LN gossip, and depending on how the user set up their node, it is either a tor url or their ip address. If such a user then creates an invoice, anyone can look ip that user's network string.
As a result, if you have ever had any public channels, you are at risk of exposing your ip address via your invoices unless you run your node on tor. Running on tor thus sometimes helps your invoices hide information about your node -- specifically, its ip address.
"Anyone" -- oops, I should have said "the sender," not "anyone."
