中国检察官公众号：办理虚拟货币洗钱案件应以钱包地址为突破口

Odaily: The WeChat public account "China Prosecutor" published an article titled "Key Points for Cross-border Electronic Evidence Collection in Virtual Currency Money Laundering Crimes," which points out that in handling virtual currency money laundering cases, investigators should use virtual currency wallet addresses as a breakthrough point. By leveraging blockchain technology to analyze on-chain data characteristics and fund flow paths, they can identify money laundering activities conducted through virtual currencies and achieve precise crackdowns.

The article proposes that, focusing on the two core proof elements of identity correlation and transaction correlation, an evidence collection model should be established based on "domestic evidence collection as the foundation, cross-border evidence collection as a supplement." It also recommends standardizing the application boundaries between unilateral evidence collection and bilateral judicial assistance to improve the efficiency of cross-border evidence collection.

For third-party entities such as exchanges, wallet service providers, and payment gateways, the article suggests establishing "element-based" data retrieval standards. Key data to be obtained includes KYC information and change records, login logs, device and IP information, two-factor authentication records, deposit and withdrawal records, on-chain addresses, transaction hashes, as well as risk control and freezing records, in order to establish the correlation chain of "address — account — natural person."
