Probabilistic proofs: theory, hardware, and everything in between

Speaker: Riad S. Wahby, Stanford University

Location: Online

Date: April 1, 2021, 10 a.m.

Host: Jinyang Li


In the past decade, systems that use probabilistic proofs in real-world
applications have seen explosive growth. These systems build upon some
of the crown jewels of theoretical computer science---interactive proofs,
probabilistically checkable proofs, and zero-knowledge proofs---to solve
problems of trust and privacy in a wide range of settings.

This talk describes my work building systems that answer questions ranging
from "how can we build trustworthy hardware that uses untrusted components?"
to "how can we reduce the cost of verifying smart contract execution in
blockchains?" Along the way, I will discuss the pervasive challenges of
efficiency, expressiveness, and scalability in this research area; my approach
to addressing these challenges; and future directions that promise to bring
this exciting technology to bear on an even wider range of applications.
