POPA ReconExploring the Design Space for a Post-Quantum Public Key Registry for Ethereum Validators
Exploring the Design Space for a Post-Quantum Public Key Registry for Ethereum Validators How Ethereum is preparing for quantum computers Quantum computers could break today’s BLS signatures. Ethereum is adding a simple “Public Key Registry” first - a safe warmup phase so validators can register tiny new quantum-proof keys before the real switch Validators register one 52-byte public key (almost same size as now) that lasts ~1,600 years. Bigger signatures are bundled using fast zero-knowledge proofs so the network stays fast and cheap Keys are generated offline in a few hours on a norma…
