Arik Galansky, VP of Technology at Fireblocks, discusses the intersection of architecture and cryptography, focusing on Multi-Party Computation (MPC) and its application to ECDSA in blockchain wallets. He explains why ECDSA is prevalent due to historical patent issues with Schnorr, and how MPC addresses key theft and self-custody concerns. Galansky details the challenges in measuring MPC protocol effectiveness, emphasizing communication rounds and scalability, and introduces a novel approach to stateless MPC using Evenly Verifiable Random Functions (EVRFs) to achieve internet-scale MPC, enabling horizontal scalability and improved security in distributed systems.
