About
Justin Thaler is a Research Partner at a16z and an Associate Professor of Computer Science at Georgetown University, focusing on verifiable computing, complexity theory, and algorithms for large data sets. In 2011 he built the first implementation of a general-purpose interactive proof system, and he wrote the survey "Proofs, Arguments, and Zero-Knowledge" and co-created the open-source streaming algorithms library Apache DataSketches. He previously worked as a Research Scientist at Yahoo Labs and earned his PhD in Computer Science from Harvard University.

All the sum-check optimizations we could come up with (some brand new from new coauthor Zach DeStefano), collected in one paper. These make a huge difference in Jolt (~11x faster, ~17x less memory for key subroutines), and can benefit almost all sum-check-based SNARKs. https://t.co/Mq4S5JzaVz

10/ Huge thanks to the Nova, HyperNova, and Vega authors for identifying such a clean and efficient technique to add zero-knowledge to Jolt. @srinathtv @abhiramko @daryakaviani Stay tuned for more major Jolt updates.

9/ The upshot: whether you want to scale blockchains with GPU provers or achieve privacy with proofs generated on a phone, Jolt has you covered.
