The idea behind EIP-8450: Don't wait for quantum computers. Get the keys ready while BLS is still secure. Validators would register a quantum-resistant key in beacon state today. It stays dormant this fork, and a later fork switches duties over to it. 🔐 Hash-based leanXMSS key + a 32-byte vrf_root, ~2.6 KB per registration 📊 The registry shows how much stake is actually PQ-ready before any switch ⚠️ Open questions: who can authorize key changes, and DVT costs flagged by Obol (~55–164 GB key shares per node) For stakers and restaking operators, there's nothing to do yet, but every validator will eventually need a PQ key. Prepare early. Switch when it's safe.👇
