摘要:

智能庞氏骗局是一种新形式的经济犯罪,使用以太坊智能合约账户和加密货币来实施庞氏骗局。智能庞氏骗局已经损害了众多投资者的利益,但目前对智能庞氏骗局检测的研究还非常有限。现有的智能庞氏骗局检测方法存在特征工程需要大量人力资源、模型可移植性差等问题。为了解决这些问题,本文提出了一种数据驱动的智能庞氏骗局检测系统。该系统使用动态图嵌入技术,基于与账户交易相关的多源多模态数据自动学习账户的表示。与传统的方法相比,该系统需要非常有限的人机交互。据我们所知,这是第一个通过动态图嵌入实现智能庞氏骗局检测的工作。实验结果表明,该方法明显优于现有的智能庞氏骗局检测方法。

英文摘要:

A smart Ponzi scheme is a new form of economic crime that uses Ethereum smart contract account and cryptocurrency to implement Ponzi scheme. The smart Ponzi scheme has harmed the interests of many investors, but researches on smart Ponzi scheme detection is still very limited. The existing smart Ponzi scheme detection methods have the problems of requiring many human resources in feature engineering and poor model portability. To solve these problems, we propose a data-driven smart Ponzi scheme detection system in this paper. The system uses dynamic graph embedding technology to automatically learn the representation of an account based on multi-source and multi-modal data related to account transactions. Compared with traditional methods, the proposed system requires very limited human-computer interaction. To the best of our knowledge, this is the first work to implement smart Ponzi scheme detection through dynamic graph embedding. Experimental results show that this method is significantly better than the existing smart Ponzi scheme detection methods.
