Fan Zhang

I’m an assistant professor of Computer Science at Yale University. I work on computer security and applied cryptography, with a focus on building systems that enhance the security of decentralized systems and applications. Several of my works, notably oracles (aka zkTLS), confidential smart contracts, trustless bridges, and efficient DC Net, have been adopted by the industry. My research has been supported by awards and grants from the NSF, the Ethereum Foundation, Flashbots, Mysten Labs, the Yale Roberts Innovation Award, and IBM.

I’m also affiliated with IC3, Center for Distributed Confidential Computing (CDCC) and Center for Algorithms, Data, and Market Design at Yale (CADMY).

At Yale, I teach Intro to Blockchain and Real-World Cryptography.
