Chenxing Li | 李辰星

I am a Research Scientist at Shanghai TreeGraph Blockchain Research Institute (Conflux), where I have been a founding member and core developer since 2018. I received my Ph.D. from Tsinghua University, advised by Professor Andrew Chi-Chih Yao.

My research focuses on the security and performance of blockchain systems, with particular interest in consensus protocols, authenticated storage, and the application of cryptographic primitives to decentralized systems. I design core features of the Conflux blockchain and have contributed to key developments including PoW/PoS hybrid consensus, heterogeneous VM interoperation, and on-chain governance.
