[Blockchain Association Urges U.S. Treasury to Clarify GENIUS Act DeFi Applicability Boundaries] According to a report by NewsBTC on October 21, the U.S. Blockchain Association has submitted comments on the Treasury's proposed Rule 3 under the GENIUS Act, calling for clearer boundaries regarding software, foreign stablecoin issuers, and liability attribution. The association argues that frameworks designed for regulated payment issuers should not unintentionally encompass unrelated software and market participants. One point of contention is the definition of "digital asset service providers." The association advocates for distinguishing between customer-facing financial services and infrastructure such as self-custody software and validators that do not provide similar services. Another issue involves how to define "knowingly participating" in illegal stablecoin issuance. The association asserts that enforcement should be based on actual knowledge and substantive assistance, and ordinary secondary market activities should not be treated as evidence of participation. Foreign stablecoin issuers are also under scrutiny. The association argues that compliance requirements should be based on accessible regulatory information, rather than assuming every service provider can investigate issuers with whom they have no direct relationship. The report emphasizes that these are industry advocacy positions and not modifications adopted by the Treasury. The final wording will determine whether GENIUS Act compliance primarily falls on stablecoin issuers or extends to a broader surrounding ecosystem.
