Chinese prosecutors have emphasized the importance of using virtual currency wallet addresses as a key entry point in tackling money laundering cases involving cryptocurrencies. According to an article published on the official WeChat account of Chinese prosecutors, leveraging blockchain technology to analyze on-chain data characteristics and the flow of funds in fraudulent schemes can help identify various money laundering activities conducted through virtual currencies. The article suggests that case handling practices should focus on the cross-border nature of electronic evidence in virtual currency money laundering crimes. It highlights the need to establish identity and transaction correlations as core proof elements and to clarify evidence collection points. By building a model that combines domestic evidence collection with cross-border supplementation, the integrity and stability of the evidence system can be enhanced. Additionally, the article calls for the standardization of unilateral evidence collection and bilateral judicial assistance, aiming to improve the precision of cross-border evidence requests and preemptive evidence standards, thereby enhancing the quality and efficiency of handling such cases.
