In this thread you linked, disgraced Samourai developer 'PavelTheCoder'
(who also was caught lying exactly like you were about WabiSabi coinjoins being traceable) calls
the issue I opened for enabling "absolutely vital" privacy features by default on Samourai wallet "a retarded change".
Whirlpool does use a central coordinator, so it is absolutely vital that you use it with your own node and Tor to keep your privacy from the central coordinator.
Samourai acts as a surveillance app, sending everyone's financial history to their servers. You claimed that it's
"absolutely vital" to keep your privacy by connecting to your full node and using Tor, and yet this
"absolutely vital" privacy improvement was
DELETED from Samourai's Gitlab repository:
https://web.archive.org/web/20230417145554/https://code.samourai.io/wallet/samourai-wallet-android/-/issues/4581 - Both Samourai and Sparrow tell you the size of your change output prior to signing and broadcasting Tx0. If you don't want to create a change output of this size, then you go and edit your transaction. This is the expected behavior of any good wallet.
Tell me why you would you ever want to send an output to yourself that costs more in sats to create than it is worth. Any good wallet would prevent you from taking this unnecessary loss.
2 - Tx0 clearly pays the coordinator, and this output is easily identified. The privacy of Whirlpool coinjoins does not depend on this fee payment being secret. It does not matter if you and I both pay to the same coordinator address - there is zero loss of privacy.
Apparently you are not aware of Samourai's statements regarding reuse of coordinator fee addresses:
https://stephanlivera.com/episode/150/Stephan Livera: Also. So recently there’s been this whole debacle around Wasabi wallet getting flagged. So essentially some users, so the two recent examples, which to my knowledge, are the third and fourth cases that I know of. So there was Catxolotl from Binance Singapore. And then the other guy was RonaldMcHodled. RonaldMcHodled was withdrawing from Paxos. And so it’s sparked up this whole debate about basically how easy is it to flag CoinJoin transactions. My perspective on it was, look, these are like an unforced error. Wasabi should not have had a fixed fee address. And in fairness to Wasabi they are now changing that, after a lot of debate and a lot of time on this topic.
Samourai Wallet: It doesn’t matter now though. The impact has already been made. There’s no going back from more than a year of address reuse. It’s tied into the architecture of the mixes now. So it’s very good that they finally changed that. But it really isn’t going to do all that much.
If this is so important to Samourai that coordinator fee addresses are not reused in Wasabi, why would they delete an issue from their Gitlab repo proving that the coordinator fee address is reused in Samourai?
