Samourai Wallet founders Keonne Rodriguez and William Hill pleaded guilty to operating an unlicensed money-transmitting business, admitting their Bitcoin mixer facilitated $2 billion in transactions, including $100 million in dark web laundering. They face up to five years in prison. Meanwhile, Roman Storm, co-founder of Tornado Cash, stands trial for allegedly enabling over $1 billion in laundering, including funds linked to North Korea’s Lazarus Group. Storm faces up to 40 years if convicted. These cases mark a pivotal moment in U.S. legal action against crypto privacy tools, with major implications for DeFi and open-source software development.
