Zhenfei Zhang

I am a cryptographer at Polyhedra Network. My professional journey includes roles at leading blockchain companies: Algorand, Espresso, Ethereum Foundation and Scroll. I write high-performance cryptography code and publish research in the field.

I organized the Sumcheck Builder Group, fostering collaboration and innovation in Zero-Knowledge Proofs and Sum-Check Protocols through regular seminars.

I contributed to Falcon signature scheme, a NIST PQC standard. I also worked on BLS standard.

Beyond research and development, I serve as an angel investor and advisor to startups, with particular emphasis on zero-knowledge technology. If you're working on innovative ideas in this space, I'd be interested in connecting.
