Fan Zhang

Assistant Professor of Computer Science, Yale University

My research is in computer security. I’m passionate about removing trust from computer systems, through decentralization, verifiability, or accountability. I study such real-world systems and build the cryptographic tools that make them possible.

Several projects I worked on, notably zkTLS, confidential smart contracts, trustless bridges, and efficient DC nets, have been deployed in industry.

My research has been supported by the NSF, the Ethereum Foundation, Flashbots, Mysten Labs, the Yale Roberts Innovation Award, and IBM. I received my Ph.D. in Computer Science from Cornell University, advised by Prof. Ari Juels, and my B.S. from Tsinghua University.

Research interests
  • Cryptographic protocols for decentralization, verifiability, or accountability
  • Economic security with rational players
  • Decentralized finance, identity, and AI applications
