zkID with Oleksandr Brezhniev

 In Module 12, Oleksandr Brezhniev of Polygon ID and host Bobbin Threadbare discuss the types of ID from physical to digital, centralized to self-sovereign and how their work on Polygon’s zkID aims to build a system for decentralized identity. Oleksandr explains how the use of blockchain technology and ZK proofs can be used as a form of identity verification.
