Chinese Prosecutors Propose Stricter Scrutiny of Privacy Coins and Crypto Mixers

Highlights:

• Chinese prosecutors propose treating crypto mixers, privacy coins and anonymous wallets as possible money laundering signals.
• Research suggests courts could rely more on blockchain records and analytics reports when reviewing crypto-related cases.
• The proposal also calls for national rules covering crypto seizure, storage, valuation and lawful disposal.

Chinese prosecutors and a legal scholar have proposed treating the use of crypto mixers, privacy coins and certain anonymous wallets as possible signs of money laundering. The recommendation appeared in a research article published on July 12 on the website of China’s Supreme People’s Procuratorate, the country’s highest prosecutorial authority.

The article was written by two officials from the Yuhu District People’s Procuratorate in Xiangtan and an associate professor at Xiangtan University. It outlines possible ways for Chinese authorities to improve criminal investigations involving virtual currencies. The proposals are professional recommendations rather than newly adopted national rules.

Crypto Tools Could Support an Inference of Intent

The authors said investigators often struggle to prove that a person knowingly helped hide criminal funds. Crypto transactions can move across borders, pass through several blockchains and involve wallets that are not directly linked to a real identity.

To address that problem, the article proposes allowing courts to infer possible money-laundering intent from certain transaction patterns unless the suspect provides a reasonable explanation. One suggested signal is the use of crypto mixers or privacy coins to hide transaction activity.

A crypto mixer combines or rearranges digital assets from different users, making the original path of funds more difficult to follow. Privacy coins use built-in technology to conceal details such as wallet addresses, transaction amounts or the movement of funds.

Other proposed warning signs include quickly disposing of large amounts of crypto through unusual prices or methods. The authors also pointed to frequent, high-value transfers through anonymous wallets with no clear connection to the user’s public identity or known source of funds.

Blockchain Records May Receive Greater Evidentiary Weight

The paper also calls for clearer standards for blockchain evidence. It suggests that transaction records verified through a public blockchain explorer could receive an initial presumption of authenticity when their identifying hash values remain consistent.

Reports from compliant blockchain analytics companies could also be accepted as specialist evidence, according to the proposal. Courts would still need to examine whether the tools were reliable, the methods were sound, and the conclusions were objective.

The authors further argued that prosecutors should be able to build a money-laundering case using connected indirect evidence. Under their suggested approach, authorities would not always need to trace every crypto transaction back to its first source or final destination when the available evidence forms a complete and consistent chain.

Proposal Also Covers Crypto Seizure and Recovery

Beyond proving criminal intent, the article recommends national rules for seizing, storing, valuing and selling crypto linked to criminal cases. It says China currently lacks a fully unified process for handling confiscated digital assets.

The authors proposed creating a national custody and disposal platform, supported by compliant methods such as targeted auctions or negotiated transfers. They also called for stronger international cooperation because crypto assets can move quickly across different jurisdictions.

The publication does not announce a change in Chinese law. However, it shows that prosecutors and legal researchers are considering how privacy-focused crypto tools, blockchain analytics, and unusual transaction behavior could shape future money-laundering investigations.
