Keonne Rodriguez, a developer of the Samourai Wallet, has been sentenced to five years in prison for his involvement in creating a bitcoin mixing service that laundered $237 million in illicit funds. Rodriguez, along with co-developer William Lonergan Hill, pleaded guilty in July to conspiracy to operate an unlicensed money transmitting business, thereby avoiding a more severe money laundering charge. This sentencing is part of a broader U.S. crackdown on cryptocurrency privacy tools, with another Samourai developer, Roman Storm, also recently convicted on similar charges.
