About Me
Hi! I am currently a third year Ph.D. Candidate 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.
If you are interested in my works, please follow me on ResearchGate for latest updates.
I am the founder and maintainer of 1000+ stars GitHub repo ccf-deadlines that helps researchers track deadlines of cs conferences.
