What it's about
Written by industrial-cybersecurity professional Luke de Wolf (foreword by Mikko Hyppönen), this applies the frameworks that protect power grids and pipelines to Bitcoin as decentralised critical infrastructure. It walks through ten concrete threats — from custodial failure and mining centralisation to quantum computing — and the layered defences, drawn from industrial standards, that address each one.
Why it matters
Security is exactly where new users most need calm, trustworthy guidance, and this treats it with unusual rigour — useful both for personal self-custody and for thinking about the network's resilience.
