Are you thinking of Wasabi? Samourai did not do chainalysis
Discussion
OXT was a chainalysis & block explorer ran by the Samourai team.
I’m vaguely aware of this and need to research more, but I was under the impression OXT was a series of open source tools to measure privacy and Samourai used them to see the effectiveness of the privacy they provided. Which you can make a pro case for and say you have to measure the effectiveness of your product somehow or con case and say it’s too risky and creates a bad incentive. At the very least I wouldn’t say throw it in the same bucket as Wasabi using an outside chainalysis firm to explicitly screen and block certain transactions. I’ve tried to research and see no evidence of Samourai blocking anyone. Also Samourai you could’ve always run your own Dojo and didn’t need to give out your xpub, another key difference versus Wasabi.
You can use any block explorer to check to see if transactions are private.
You can run your own private block explorer.
They chose to run a chainalysis outfit & a honeypot of Xpubs.
I wonder why?!
They didn't have to collect those Xpubs, they just wanted to, to make more money.
Also mentioning wasabi is a false positive comparison, as I'm not doing some BS compare & contrast as I wouldn't have used either.
In talking to people smarter than me I think there’s two points 1) since the Samourai backend is proprietary it is unknowable if there was a honeypot. They could’ve had good opsec and purged xpubs after using them or kept them forever. Impossible to know unless/until it comes out in court. 2) someone somewhere has to collect xpubs to coordinate the transactions. Oversimplifying: So your options are basically central coordinator or run your own(they called this a Dojo). Samourai provided both options. User had to elect not to run their own Dojo and divulge their xpub, it was not required. People should never give up their xpub imho
I definitely agree with the meta point of it was a mistake to use either. I don’t think they provided much if any privacy and it was clear governments were closely monitoring and likely Sybil attacking them and you only were as private as your coinjoins peers were smart about not doxing themselves, aka not very private at all.
