Hi! I am currently a third year postgraduate at school of data science and engineering (DASE), ECNU. My research interests are blockchain systems.
More specifically, I am committed to building high-performance, reliable permissioned blockchain systems from the perspectives of system architecture, sharding, authenticated data structures, zkRollup and etc.
