Exploring Security of ZK Systems with Nethermind’s Michał & Albert

On this week’s episode, Anna Rose interviews Michał Zając and Albert Garreta from the Nethermind team. They discuss the origin story of Nethermind and its role in the ecosystem today. They also delve into the cryptography research being done at Nethermind, including their work on proving the security of FRI-based protocols, identifying security issues with Fiat-Shamir, exploring topics like ZK malleability and aggregation, and building SNARKs over rings.

Here’s some additional links for this episode:
