Arguments Against Broad Crypto Mixer Reporting Requirements

Summary

The letter responds to a proposed FinCEN rule that would require reporting transactions associated with a broadly defined category of virtual currency mixing. It accepts that illicit actors can misuse crypto, but argues that the proposal targets general-purpose technologies that can also support legitimate aims such as scaling and execution optimization. The authors contend that regulation should focus on abusive actors rather than broadly covering tools that can obscure transaction details.

As an alternative, the letter points to the existing suspicious activity reporting framework for financial institutions and urges FinCEN to use or adapt its current authorities instead of establishing a wide new reporting regime. It also argues that broad requirements could push blockchain development offshore and harm national security interests. The document is an advocacy submission, not an empirical assessment: it provides no data measuring the proposal’s likely effects or comparing enforcement outcomes under alternative rules.

Key ideas

• The proposed rule would impose reporting duties on transactions associated with a broadly defined class of mixing activity.
• The authors distinguish general-purpose privacy or transaction technologies from the bad actors who may misuse them.
• The letter argues that existing suspicious activity reporting tools can address illicit finance concerns.
• It warns that broad reporting obligations could shift blockchain development offshore.
• The document presents a policy position and does not quantify the effects of the proposed rule.
