About Me

Hi! I am currently a Ph.D. student 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, secure permissioned blockchain/ledger systems from the perspectives of system architecture, transactional smart contracts, 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.

I have broad interests in cryptography, graph databases, and TEEs. I am still twisting and struggling with indirect hesitation and persistence, to catch up my important 3 SIGMOD deadlines.
