The hosts mention the podcast's Discord community and introduce the sponsor of the week, Nomada, a proof of stake L1 blockchain. They then introduce Ulrich Habak, an applied cryptographer at Polygon Labs, and discuss the topics they will cover during the interview.
In this week’s episode, host Anna Rose and cohost Nico Mohnblatt catch up with Ulrich Haböck, an applied cryptographer at Polygon Labs. This episode revolves around Ulrich’s journey into applied zero-knowledge cryptography, transitioning from an academic environment to being a full-time practitioner. They discuss his contributions to the field, including his many write-ups and manuscripts as well as his breakthrough research on Multivariate lookups with his work logUp. They also cover his work on logarithmic derivative lookups using GKR with Shahar Papini, as well as his innovative approaches to STARKs over finite fields that are not ‘NTT-friendly’. This episode offers a deep dive into the complexities and breakthroughs in applied cryptography.
