Bybit and HKU Students Collaborate on Anti-Money Laundering Research

In a groundbreaking initiative, Bybit, the world's second-largest cryptocurrency exchange by trading volume, has partnered with students from The University of Hong Kong (HKU) to tackle anti-money laundering (AML) issues through a hands-on approach. The collaboration culminated in a unique challenge that allowed the students to engage in practical cryptocurrency investigations, utilizing advanced machine learning techniques against real-world scenarios.

The Context of the Collaboration

This partnership was initiated following a significant security breach faced by Bybit in February 2025. The breach served as a compelling case study, allowing students to delve into the intricacies of blockchain analytics and machine learning applications to trace laundering activities linked to cryptocurrency mixer operations. The direction of the project was expertly guided by Professor Doyeon Kim, who teaches Accounting and Law at HKU. Professor Kim's academic insights, combined with industry context provided by Bybit, helped students understand the complexities of cryptocurrency-related financial crimes.

Focus Areas and Methodologies

Under the guidance of David Zong, the Head of Group Risk Control and Security at Bybit, students embarked on a mission to track funds linked to the infamous Lazarus Group, an entity known for its cryptocurrency-related illicit activities. The students were tasked with analyzing various wallet addresses implicated in laundering operations and systemizing their findings through advanced machine learning methodologies.

Bybit effectively facilitated this collaboration, allowing students the freedom to choose their analytical paths. While some teams leveraged existing blockchain tracing techniques, others experimented with innovative machine learning models and graph analytics to dissect transaction patterns associated with digital currency mixers. This open-ended structure encouraged creativity and independent research, leading to a diverse range of solutions and methodologies.

The Research Journey

Over the span of several weeks, participants refined their approaches through constant iteration, collaborative discussions, and feedback from Bybit conducted mid-term reviews. Students gathered comprehensive datasets, analyzing about 49,800 Bitcoin blocks and over 146 million transactions. Utilizing sophisticated clustering models and graph neural networks, the teams successfully identified transactions that were similar to those of Wasabi, generating a network that contained over 1.6 million address nodes, illustrating the extensive reach of cryptocurrency laundering practices.

The findings revealed a significant capability of their machine learning model, achieving a recall rate of 70.5% in identifying addresses tied to the Democratic People’s Republic of Korea (DPRK). These outcomes not only exemplify the project’s impact but also highlight the continuing challenges presented by cryptocurrency mixers designed to obscure transaction histories and complicate investigations.

Personal and Academic Growth for Students

Students who participated expressed how this collaboration enhanced their understanding of anti-money laundering systems and cryptocurrency security operations firsthand. One participant remarked on the project’s educational value, asserting that it illustrated the importance of AML technologies in hindering criminal activities and emphasized the multifaceted nature of tackling real-world industry problems.

Moreover, many students acknowledged that their initial expectations were exceeded, with learning outcomes that encouraged deeper engagement with topics surrounding blockchain security and compliance. Participants noted how the project presented a rich understanding of Bitcoin's transactional landscape and its implications for the future of blockchain-based financial systems, pivotal for aspiring professionals in finance and technology.

Looking Ahead

This partnership showcases the burgeoning interest from both academia and industry in deploying machine learning and blockchain analysis to real-life cybersecurity and compliance challenges. Bybit’s commitment to engaging with emerging talent demonstrates an investment in the future of cryptocurrency regulation and security. The initiative not only benefited the students by providing real-world experience but also enabled Bybit to enhance its strategic contributions to academic research.

In conclusion, Bybit's collaboration with HKU marks a significant step forward in the fight against financial crimes in the cryptocurrency space, bridging the gap between education and practical application. The insights gained from this project may very well contribute to shaping the future of compliance and anti-money laundering efforts within the cryptocurrency sector.
