This week, Anna and Nico catch up with Srinath Setty, researcher at Microsoft. They look back at his research since his work on Nova, spanning lattice-based folding, zero-knowledge identity proofs, and lookups and memory checking, much of which traces back to his 2019 work, Spartan.
The bulk of the conversation is on Magnetar, his newly released zkVM. Built only on standard hash functions, it aims to be among the most secure general-purpose zkVMs, and it also turned out to be dramatically faster than many existing systems. Srinath explains how it’s put together, where the speed comes from, and what’s still left to build.
