About Me

Hello 👋, I'm currently pursuing my Master's degree at Zhejiang University under the supervision of Prof. Jian Liu. Prior to this, I earned my Bachelor's degree from Wuhan University, where I actively participated in CTF competitions as part of the team DAWN and SU, focusing on reverse engineering and Android security.

After beginning my Master's studies, I shifted my focus to the emerging field of blockchain, particularly its security aspects. I am eager to engage in innovative and impactful work, addressing real-world challenges in this dynamic domain.

🎓 Education

• Zhejiang University (2023 - Present) Master's in Cyberspace Security
• Wuhan University (2019 - 2023) Bachelor's in Information Security

🧐 Research Journey

I have conducted research on several topics, including MEV, DeFi Security, and Scalability. However, as a novice researcher, coming up with great ideas can be challenging, while simpler ideas often demand quick realization to stay competitive, making tangible outcomes difficult to achieve. 🤣
So far, I have no published works, with two preprints still under submission.

• LookAhead: Preventing DeFi Attacks via Unveiling Adversarial Contracts Shoupeng Ren, Lipeng He, Tianyu Tu, Di Wu, Jian Liu, et al.
  This work addresses the growing challenge of attackers using private mempool services to conceal their adversary transactions. By analyzing the features of DeFi attacks, we propose a method for detecting adversarial smart contracts, offering a new direction for real-time defense mechanism. On the Atomicity and Efficiency of Blockchain Payment Channels Di Wu, Shoupeng Ren, Yuman Bai, Lipeng He, Jian Liu, Wu Wen, Kui Ren, Chun Chen.
  This work analyzes the inherent security risks in Lightning-style payment channels caused by non-atomic state transitions. To address this issue, we propose a novel payment channel protocol that guarantees atomicity while significantly reducing latency.
