Exploring the Design Space for a Post-Quantum Public Key Registry for Ethereum Validators

Authors: Thomas Coratger , Tom Wambsgans , Ladislaus , Thomas Thiery , Justin Drake As outlined in the Strawmap roadmap , securing Ethereum against the looming threat of large-scale quantum computers is a top priority. A critical milestone in this transition is migrating our proof-of-stake consensus from BLS signatures to a post-quantum (PQ) secure signature scheme. This post aims to explore the concepts and design space for a Post-Quantum Public Key Registry. Importantly, the actual transition will happen in phases: the Public Key Registry fork will occur first, enabling validators to registe
