The U.S. authorities have successfully seized assets linked to a money laundering operation orchestrated by Chen Zhi through his Huione Group. Chen allegedly used the Lubian mining pool to convert illicit funds into Bitcoin. In 2020, Lubian claimed a hack resulted in the loss of 127,000 BTC, but it was later revealed to be a cover for Chen's self-directed fund transfer. Following a detailed blockchain analysis, U.S. officials obtained the private keys necessary to confiscate the assets. Although Chen remains at large, the core funds of the fraudulent operation are now under U.S. control. This case highlights the enhanced traceability and regulatory capabilities of blockchain technology.
