Quantum computers could one day threaten today’s signatures. Mining remains safe longer, but signatures (ECDSA) are the main concern.

Simple definitions:

•Shor’s algorithm: Could break current signature schemes when quantum is strong enough.
•PQ (Post‑Quantum) signatures: New kinds of signatures designed to resist quantum attacks.
•Migration: A careful plan to move to safer signatures if/when needed.
