Is there a ln setup (self-custodial or trusted 3p) that makes transactions private?
Discussion
I am not a privacy expert. That said, for serious privacy, I would start with this:
- Get a dedicated device
- Install TailsOS on it
- Download a bitcoin node and electrs
- Open electrum (comes with TailsOS)
- Set it to use your node (not electrum servers)
- Set it use tor (probably automatic on TailsOS, but check)
- Send bitcoin to electrum via a coinjoin
- Open channels with privacy focused peers (e.g. ecash mints)
You will need almost 1 TB of disk space for a bitcoin node
TailsOS will be terrible to do any normal web browsing on because of the Tor blocks / CLoudflare CAPTCHAS
since it's a "dedicated device" for lightning transactions, it's not for web browsing

not if you do transaction pruning...though then there is some additional setup to ensure you can get the blocks you need when LN needs them
Ah .... then......just use a regular Linux distro
Tails is not persistent
Me after reading this thread:

This device has to be online 24x7 to keep channels open in lightning right?
No, my node is off pretty much all the time, I just turn it on when I need to make a payment
Though in order not to have to trust my counterparty, I do have to "check in" (i.e. open the wallet) once every two weeks or trust a watchtower
