somewhat recently cake wallet added silent payment support to their bitcoin wallet. I don't ever use bitcoin so I was unaware of the tech until then. it seems to work similarly to monero's remote node scanning & is said to enhance privacy.

im wondering how it weighs against moneros privacy protections & what this development may or may not mean for the project in the future. im worried about the way it may overshadow XMR due to bitcoins reach & possible consequences if it is inferior tech (being based on a transparent L1 & all). however it is also a big step towards closing the gap between the privacy coin community & the BTC maxis (which is probably only good for eveyone involved). so im feeling split & figured i would ask the community what they think of the development.

it seems to be more like hiding coins in different addresses while obscuring it on chain & using some clever math to make the UX better. aswl as not giving over ur key to the remote node. although Ill admit the technical stuff is slightly about my head so please correct my explanation as needed haha.

im more so wondering about the practical use/implications when it comes to privacy & was struggling to find a good comparison online.

As far as Bitcoin goes, there's also coinjoin. Lightning transactions are pretty opaque since they don't occur on L1. If I have a lightning node (which I run on an android phone), and you have a lightning node, and we make a tx between each other, nobody knows it. Even for a multi-hop transaction, nobody aside from those hops knows about it. Setting up a lightning channel requires an L1 transaction, but you can make a lightning channel with anybody and then send funds to anybody, it's not a 1:1 relationship. In other words, if I want to send you money via lightning, as long as I have an existing lightning channel with somebody else, I can do it.

Bitcoin's privacy continues to get better, it's a common refrain at Bitcoin conferences that privacy needs to be focused on more. Monero is still king here but it's losing ground in this area. Bolt12 is a new thing being implemented that helps with privacy as well.

With whirlpool going out of biz, what coinjoin is there for btc?

LN stuff

Doesn't work when mempool fees are high
Most people are forced/nudged into using custodial wallets
LN was not designed to be a privacy tool. Bitcoiners tried to shoe-in that it is also a privacy tool

Monero is losing ground to LN

Where are LN darknets?

There's plenty for anybody who want to research. Coinjoin is a technique.

Doesn’t work when mempool fees are high

LN is disconnected from mempool, that's the entire point of an L2. Your transactions don't go on chain or in the mempool. Main chain secures the transactions, lightning stores the transactions. The main chain only stores the start and end balance of a lightning channel, that's it.

Most people are forced/nudged into using custodial wallets

Their choice, some people will always prefer custodial options no matter how easy non-custodial ones are. LN works fine non-custodially, that's how I use it. You move money from L1 to L2 in a single tx. Now you have a lightning channel that can have functionally unlimited transactions in it between you and anybody else on lightning. Transactions confirm in a second for pennies in fees.

Privacy continues to enhance, look at the Bolt12 upgrades for example. But I agree, and Bitcoin can't hold a candle to Monero's level of privacy.
