Stateful ZK Identity with Ian Miers
Wed Feb 04 2026
In this episode, Anna Rose and Nico Mohnblatt welcome back Ian Miers, Assistant Professor of Computer Science at the University of Maryland, to continue the conversation from a previous episode and dig deeper into his latest work like zk-Promises, zk-Cookies, and Cryptographic Personas. These ZK tools aim to build social networks that protect user privacy while maintaining integrity, like anonymous moderation and reputation systems without central databases. Ian explains how they differ from traditional creds but share ideas around proving attributes securely.
The conversation explores real-world applications, such as banning bad actors without de-anonymizing them, setting rules in private group chats, and creating self-sovereign identities that persist over time. Ian also touches on challenges like stolen accounts, trolling, age checks, and how these primitives could shape future online interactions.
