最新报道:US lawmakers are pushing for blockchain firms to comply with Treasury Department sanctions by restricting access to decentralized protocols. Representatives Sean Casten and Bill Foster wrote to Treasury Secretary Janet Yellen urging action against crypto mixers and privacy tools that allegedly enable illicit finance. The letter follows Treasury's sanction of Tornado Cash last year, which faced legal challenges. Blockchain Association CEO Kristin Smith argues such measures could stifle innovation while failing to curb crime. The debate highlights tensions between regulatory oversight and preserving blockchain's decentralized nature as policymakers grapple with emerging technologies.
