Winning First Prize#
I was invited to participate in the hackathon as a member of the Peking University InfoSec Laboratory team (supervised by Professor Chen Zhong and Associate Research Professor Guan Zhi). The six students of our lab were divided into two groups. The first group, composed of Abba Graba, Ke Wang, and Li Yue, focused on improving blockchain consensus protocol for the Internet of Things. I, Liu Chao, and Li Anran formed the second group (Team 18: Yet Another Atomic Swap), tackling the topic of atomic swaps on decentralized exchanges.
After two sleepless nights and a lot of caffeine, our group proposed an improvement plan for the decentralized trading platform Cybex, which consists of design and code implementation. With a profound understanding of the problem, perfect plan design, and excellent on-the-spot performance, our team advanced to the final six and won the first prize award.
