About this episode
In this episode, Anna and Nico speak with Vadim Lyubashevsky, research scientist at IBM Research, about the evolving field of lattice-based cryptography and its role in zero-knowledge systems.
Vadim shares the history and mathematical foundations of lattices, and explains how they might be used to build post-quantum secure ZK proofs and SNARKs. The conversation covers the unique challenges of adapting lattice techniques to zero-knowledge, explores the tradeoffs relative to hash-based constructions, and highlights the importance of developing quantum-safe standards for the future of cryptography.
