CBDC - Technology, Privacy, Security and Tracking Illegal Activities

2 November (Tuesday)

3:30 - 4:30 PM  HKT

(This panel was moved online due to adverse weather.)

The Hong Kong Monetary Authority began its research on central bank digital currencies (CBDCs) in 2017 to better understand its feasibility, implications, and potential uses at the wholesale level.


How can we keep up with technologies as it continues to reshape business and financial applications?


Join this HKU FinTech Day 2022 panel in discussions on the technical architecture (Blockchain) for CBDCs, security and privacy measures, the gap between private and public information, artificial intelligence’s ability to trace illicit transactions and more!



Opening remarks:

Professor Tak-Wa Lam, Executive Director, HKU-SCF Fintech Academy and Head, Department of Computer Science, The University of Hong Kong
