My advertised service doesn’t promote themselves as the solution to Bitcoin privacy, doesn’t claim it’s non custodial or trustless. They’re sincere and at this point I much rather use them than your sketchy software.
If they were sincere, then why are they requiring their customers to trust them with their funds in privacy instead of coordinating trustless noncustodial WabiSabi coinjoins? There's no excuse for them collecting the funds and data of their customers when WabiSabi allows them to provide trustless privacy.
I do believe they had the choice to be honest and tell their users they have to shut down & maybe start working on a new, decentralized product. But it seems like they chose to give in and start spying & censorship to be able to let the business continue as usual.
What is your design proposal for a new, decentralized privacy product? I'm open to suggestions.
It obviously can't. If your coins are refused, you have no idea if it is due to Sybil attack or if Coinfirm has simply decided your coins are naughty and are not allowed to be coinjoined.
You would know because the coin is private, therefore it can't be refused due to its history.
What if:
- I don't have private coins?
Then get some if you are really that paranoid about testing for Sybil attacks.
- Both my private and non-private coins are accepted, but every single other (from the round) is denied and replaced with third party's coins?
How would the malicious coordinator know not to deny and replace your private coin with every single other one?...
