Implementing LatticeFold with Matthew and Albert from Nethermind

In this episode, x.com/AnnaRRose and Nico (x.com/nico_mnbl) speak with Matthew Klein (matthewklein.co.uk) and Albert Garreta (x.com/0xAlbertG) from Nethermind (nethermind.io) about their work implementing and advancing lattice-based cryptography systems, particularly focusing on folding schemes and their applications in zero-knowledge proofs.

Matthew and Albert share insights from their implementation of LatticeFold and discuss the evolution of lattice-based systems, including newer developments like LatticeFold+ and Neo. The conversation explores the unique challenges and opportunities of working with lattice-based constructions, from performance optimizations to post-quantum security considerations. They also dive into their work on post-quantum signatures for Ethereum, light zkML solutions, and the Zinc project, which offers a novel approach to handling integer-based constraints in zero-knowledge proofs.
