【Abstract】With the widespread application of blockchain technology, the cyberspace security issue of phishing has also appeared in the emerging blockchain cryptocurrency ecosystem. Because phishing fraud in cryptocurrency transactions has its own unique characteristics compared to traditional phishing, many existing phishing detection algorithms are not usable. Therefore, based on graph convolutional networks, we have researched and built a high-performance model for detecting blockchain cryptocurrency phishing fraud. Our model divides the constructed blockchain cryptocurrency transaction graph into "Sender" and "Receiver" graphs, according to the sending and receiving directions. Then, the edge features in the graph are transferred. Finally, we use a double-layer graph convolution network for feature learning and send it to the classifier for fraud detection. After completing training on the actual dataset collected from Ethereum, the model achieved an accuracy of 88.02% and an F1 score of 88.14% on the test data, which had a better performance than that of the other models. Our model provides a new concept for the detection of phishing scams in blockchain cryptocurrency networks.
