加密货币洗钱犯罪的侦查取证研究

Investigative and Forensic Research on Cryptocurrency Money Laundering Crimes

随着去中心化金融的飞速发展,区块链的匿名性和去中心化性质逐渐吸引到一些试图或正在进行非法洗钱活动的犯罪分子。现如今,犯罪分子多选择利用加密货币进行洗钱犯罪,使非法资金流动到全球若干个网络金融站,利用各种不同的程序进行处理,直到它再次作为“合法和干净的钱”回到它的起源,致使非法商业交易的收益难以被追踪。因此,越来越多的法规被制定出来,以禁止和监督加密货币的使用。本文建立了一个调查去中心化金融(DeFi)洗钱犯罪的框架,简要解释了犯罪分子如何利用加密货币实施网络洗钱犯罪的类型,以及如何利用区块链的数据收集、数据保存、数据处理和数据展示等性质收集犯罪证据,对此类犯罪行为进行有效的取证侦破。

With the rapid growth of decentralised finance, the anonymity and decentralised nature of the blockchain is attracting criminals who are attempting to or are engaged in illegal money laundering activities. Today, criminals are choosing to use cryptocurrencies to commit money laundering crimes, allowing illicit funds to flow to several online financial stations around the world, using a variety of different processes until it returns to its origins as "legal and clean money", making it difficult to trace the proceeds of illegal business transactions. As a result, more and more regulations are being developed to prohibit and monitor the use of cryptocurrencies. This paper establishes a framework for investigating decentralised financial(DeFi) money laundering crimes, briefly explaining how cryptocurrencies are used by criminals to commit types of online money laundering crimes and how the nature of blockchain data collection, data preservation, data processing and data presentation can be used to gather evidence of crimes and effectively detect such crimes forensically.
