Gate News 消息,3 月 9 日,美国财政部在提交给国会的一份报告中承认,加密货币混币器可以被用于合法的金融隐私目的,合法用户可以通过混币器在公共区块链交易中保护个人财富、商业支付或慈善捐赠的敏感信息。这是自 2022 年制裁 Tornado Cash 以来的立场转变。报告区分了托管型与非托管型混币器,托管型混币器已被要求向 FinCEN 注册为货币服务企业,但未建议对非托管型混币器施加新限制,也未最终确定或支持 FinCEN 2023 年提出的混币器相关记录保存规则,而是引用总统工作组报告建议财政部在平衡非法金融风险与隐私关切的同时"考虑下一步措施"。报告同时披露,朝鲜网络犯罪分子在 2024 年 1 月至 2025 年 9 月期间窃取至少 28 亿美元数字资产,并例行使用混币器进行多步骤洗钱。自 2020 年 5 月以来,超过 16 亿美元来自混币服务的存款流入跨链桥,其中逾 9 亿美元集中在一个与朝鲜洗钱有关的桥上。财政部建议国会制定针对数字资产的"hold laws"安全港机制,允许金融机构短期调查期间临时冻结可疑资产,并明确 DeFi 参与者反洗钱义务,同时提议在《爱国者法案》中增加"第六项特别措施",授权财政部对某些数字资产传输施加限制。
