About
Prof. David Yang is an Associate Professor of Computer Science at Purdue University. He is an applied cryptographer and a privacy researcher. His research builds on and expands applied cryptography, distributed computing, and data-driven analysis to solve security/privacy problems in decentralized environments. His current projects focus on communication privacy and distributed ledgers (or blockchains). He is a recipient of the 2019 NSF CAREER Award.
Before joining Purdue in 2015, he was a junior faculty member at Saarland University, Germany. He completed his postdoctoral fellowship at Max Planck Institute for Software Systems (MPI-SWS), Germany. He has received his PhD from the University of Waterloo, Canada, and his masters from IIT-Bombay, India.
Interests and expertise
15+ years of research experience in applied cryptography, distributed systems and digital privacy. 9+ years of involvement in blockchain research. Dr. Kate focuses on bridging the gap between theory, practice, and real world utility
Affiliated with Purdue University (on leave), Max Planck Institute for Software Systems (MPI-SWS), University of Waterloo, and IIT-Bombay. Recipient of the 2019 NSF CAREER Award. K in the KZG Polynomial Commitments, aka Kate Commitments, are the basis for most ZK Proof Systems today and underpin the brea kthroughs in scaling for Ethereum 2.0.
Commentary
14 years of research experience in applied cryptography and security systems. Research discussions and collaborations with the Supra team since its early years. H-index 40+. Passionate in designing and implementing secure and scalable consensus protocols and zero-knowledge proofs, as well as system pen-testing and incident response.

Christiane Kuhn, David Yang, Thorsten Strufe • arXiv preprint arXiv
“As DeFi grows, the next generation of blockchains will have to be comprehensive. What I mean by that, is the same set of blockchain system nodes have to be utilized for the oracle network providing randomness services, automation networks, and so on.”
