Abstract:

With the rapid development of blockchain, using ethereum to engage in pyramid selling, fraud, and money laundering crimes has increased year by year. Therefore, the detection of ethereum accounts has become an effective method to crack new types of crimes. The information was integrated into the characteristics of the ethereum address and account as a model to detect whether the account was a malicious one. The model in this paper improves the the neural network of graph attention mechanism and the time-series transaction information to realize the final expression of the address account characteristics. It is verified by experiments that the purposed model is superior to the graph neural network classification algorithm established by the traditional classification method.

Key words: graph attention mechanism, time kernel function, ethereum accounts
