also, the receiver only knows the IP address of the request for the invoice, not the lightning node that will originate the payment. using tor to fetch invoices closes this hole too. what's hard about lightning is the implementations have many design features that make them unstable and the source-routed onion design, like all source routed protocols, suffers from the existence of congestion and dead points in the path. this could also be fixed using atomic multipath redundant onions, but isn't possible unless the message size is increased (8kb is a good size) so that you can add a fork and join operation, and an atomic race-based cancellation of the later arriving sidepaths. there is solutions, just that nobody with an idea is being paid to build them. instead, at least this person writing it, is stuck building front end GUIs and supporting adoption of my relay project. i love the relay but i wish i could work specifically on lightning. between taproot and segwit and the slow progress of lightning to solve the obvious problems i'm getting tired of bitcoin too. not to mention the miner centralization problem and this opens up cooption to state-level actors.

Ok dude I didn’t even bring up Monero. Ok point me to a resource instead of being a dick about it believe it or not I like Lightning but from what I have read on chain settlement is still a big privacy risk. Maybe it’s outdated but I read the this guide recently https://www.voltage.cloud/blog/lightning-privacy-for-beginners and have done other research so I’m sorry I am not a genius like you and don’t know how lightning works.

Ephemeral in thoery...except that most LN node software saves and stores transaction info by default, and you also don't control what info other nodes save. Peter Todd did a talk on this problem a few months ago showing how his node still had transactions he made over a year ago. Onion layers aren't a magic barrier. Tor has a long list of attacks that can reduce or completely deanonymize you. Now consider that even if you use LN in a private way (vast majority do not) less than 1% of lightning nodes hold over 99% of total liquidity... https://www.youtube.com/watch?v=r3iFrkESigo https://github.com/Attacks-on-Tor/Attacks-on-Tor
