Bitcoin's Quantum Problem: Three Ways Researchers Are Trying to Fix It
60-second summary
Researchers tackle Bitcoin’s “quantum problem” with three advances: a cost‑effective post‑quantum signature scheme dropping implementation expenses below $1 million, a novel privacy‑preserving protocol that shields transaction data from quantum attacks, and a detailed custody playbook guiding custodians on quantum‑resistant key management; together they shift mitigation from theory toward practical safeguards, easing market concerns about future quantum threats.
Three developments this week—a cost breakthrough, a new privacy design, and a custody playbook—show a field moving from theory to logistics, even as "Q-Day" remains hypotheti
