Is there anywhere doing a comparison of bitcoin and monero, especially with regards to privacy gains added via silent payments, lightning, and ecash?
Discussion
first thing to point out is there can never be monero lightning
You misread my response cuz that's obvious.
it's very important though because that means their capacity is very limited, it's one of the things they never address too, the moneros
also, ecash is not private without a competent denomination and mixing design, and probably the use of tor, where lightning itself uses a tor-style but source routed private payment path scheme
This is just straight up false
Seraphis and FCMP++ open the door for LN channels
Ecash is pretty damn private and on par with Monero I would say (if not more so since there is no blockchain) when directly using it's tokens (not as much when making payments out of the mint over lightning). Except yea you know the big drawbacks with ecash. Can also do things that Monero can't like offline payments, instant payments, etc
When used with your own node lightning has good sender privacy. Bad receiver privacy. And amount privacy is not guaranteed from larger routing nodes.
Silent Payments are an improvement on on-chain receiver privacy for sure, particularly third parties, but your counter party can obviously determine what address it went to if they wanted and can follow from there if you're not careful.
mleku brought up that ecash doesn't have network level privacy, which is true, but neither does anything else
You have to mask your IP somehow or use tor/i2p/or some other mixer
Monero does offer default IP protection from other nodes via Dandelion++, but your ISP can still associate your transactions with your IP in a worst case scenario (although they wouldn't know amounts or receivers, just that a Monero transaction originated from your IP iirc)
