Improving Robustness and Accuracy of Ponzi Scheme Detection on Ethereum Using Time-Dependent Features

no code implementations31 Aug 2023 Phuong Duy Huynh, Son Hoang Dau, XiaoDong Li, Phuc Luong, Emanuele Viterbo

The contract-code-based approach, while achieving very high accuracy, is not robust: first, the source codes of a majority of contracts on Ethereum are not available, and second, a Ponzi developer can fool a contract-code-based detection model by obfuscating the opcode or inventing a new profit distribution logic that cannot be detected (since these models were trained on existing Ponzi logics only).
