Joinmarket, the Bitcoin tumbler service apparently popular among darknet market aficionados today announced that their service isn't actually very anonymous after all. Project developer Chris Belcher (WOT:nonperson) stated that "there are some possible vulnerabilities which could be exploited to spy on every user." While this was identified approximately one year ago, nothing was done to remedy the issue until multiple users noticed deanonymizing attacks happening in real time. Belcher assures his users that "We have a pretty good idea how to fix this" and after discussing the matter with CoinJoin creator Gregory Maxwell (WOT:gmaxwell) they together suppose they have an algorithm that will make it more difficult for attackers to uncover information on utxo's. It was admitted that "This algorithm is not intended as a complete solution to that issue" leaving darknet market users with another steaming pile of shitware.
