摘要:

近些年来,利用“去中心化”金融DeFi实施犯罪的新型作案手法已初露端倪。尤其是智能合约代码的违规部署和应用在虚拟货币涉传涉诈类案件中呈逐年上升趋势。由于DeFi协议框架下反洗钱和KYC要求被免除,涉案交易过程无法从中心化机构调取证据,开源且无须许可的智能合约易于复制和修改,混币程序和跨链交易等深度匿名交易手段通过DeFi得以应用,导致各类DeFi犯罪的资金链路隐蔽且复杂,难以通过传统侦查方法予以穿透。对此,需要分析DeFi分层系统中引发安全漏洞的因素,以此为基础对DeFi犯罪做出类型化分析,进而围绕不同犯罪模式与智能合约创建特征之间的映射关系开展虚拟货币资金流研判工作,利用合约协议引出的关键线索实现案件“破局”。

  • dc.description.abstract
  • In recent years, a new method of committing crimes by using decentralized financial DeFi has emerged. In particular, the illegal deployment and application of smart contract codes in the cases of virtual currency involving transmission and fraud are on the rise year by year. Due to the exemption of anti-money laundering and KYC requirements under the framework of the DeFi agreement, the involved transaction process cannot be transferred from the centralized institution, the open source and unlicensed smart contract is easy to copy and modify, and the deep anonymous transaction means such as currency mixing program and cross-chain transaction are applied through DeFi, resulting in the hidden and complex financial links of various DeFi crimes that are difficult to penetrate through traditional detection methods. In this regard, it is necessary to analyze the factors that cause security vulnerabilities in the DeFi layered system, and make a typological analysis of the DeFi crime based on this, and then carry out the research and judgment of the virtual currency capital flow around the mapping relationship between different crime patterns and the characteristics of smart contract creation, and use the key clues derived from the contract agreement to achieve the "breaking" of the case.
