Research Interests

Kejun’s research focuses on Bitcoin and Blockchain via operations research methodologies. One of the projects investigates the dynamics of repeated Bitcoin mining games. Given the limited monetary budget and mining power capacity, the work considers dynamic interactions among miners and explore Nash-equilibrium for the network. Under fluid and mean-field approximations, the team solves for the fluid mean-field equilibrium (FMFE) and obtain the FMFE-based individual mining strategy. In another project, Kejun builds a Monte-Carlo simulation model to study the miners’ and mining pool managers’ decisions in the Bitcoin blockchain network. The simulation model aims to capture the dynamics and participants of these two different layers and how their decisions collectively affect the behavior of the system.
