China's Prosecutors Propose Treating Crypto Mixers as Money Laundering Evidence

Prosecutors' Proposed Standards

China's Supreme People's Procuratorate, the country's top prosecutorial body, published proposals in its official paper that would shift the evidentiary burden in crypto money-laundering cases. Under the proposals, use of mixers and privacy coins would be treated as a sign of laundering intent rather than requiring prosecutors to prove intent independently. The proposals also call for new rules governing how blockchain evidence is admitted in court and for the establishment of a state platform to liquidate seized cryptocurrency.

Regulatory Intent and Scope

The proposals reflect Beijing's ongoing effort to restrict cryptocurrency activity within China, building on years of bans on crypto trading and mining. By treating mixer and privacy-coin transactions as presumptive evidence, prosecutors would lower the threshold for charging individuals and entities with money laundering. The move does not constitute law yet — the Procuratorate publishes policy recommendations that may or may not be adopted by lawmakers — but signals the direction of prosecutorial thinking as China continues to tighten its stance on digital assets.

Implications for Privacy-Focused Protocols

If adopted, the proposals would effectively criminalize the use of privacy-enhancing tools in China, even for users without laundering intent. The presumption of guilt based on tool use alone represents a departure from standard legal practice in most jurisdictions, where intent must typically be proven. The proposals underscore China's hostile regulatory posture toward decentralized finance and privacy-focused blockchain projects.
