Long (300 words)

Luke de Wolf is an ICS cybersecurity professional, podcaster, author, and Bitcoin advocate. He grew up in Calgary, Alberta and studied computer science. An internship at a major oil and gas pipeline company introduced him to industrial control systems, where he discovered that securing physical systems was more compelling than writing code. He has spent over a decade working with the systems that keep critical infrastructure running, from pipelines and refineries to power generation and maritime operations. He currently works at Wärtsilä, a Finnish industrial company. Luke holds the CISSP (Certified Information Systems Security Professional) and GICSP (Global Industrial Cyber Security Professional) certifications.

Luke discovered Bitcoin during the COVID lockdowns, around the same time he moved from Canada to Finland. He co-hosts the Bitcoin Infinity Show with Knut Svanholm. The pair previously launched the Freedom Footprint Show, which later went independent and rebranded. Luke and Knut also co-founded Lemniscate Media, where they re-edited and re-released all of Knut's books, and co-authored Bitcoin: The Inverse of Clown World in 2024. The two are often found playing rock and metal at Bitcoin conferences as part of the Satoshi Rockamoto concert series.

Luke is a co-founder of BTCHEL, the first large-scale Bitcoin conference in the Nordics. The inaugural edition drew more than a thousand attendees, with keynotes from Jeff Booth and Mikko Hyppönen. Prior to finding Bitcoin, Luke co-hosted all 53 episodes of the Northern Myths Podcast with Dan Larabie, an exploration of the Norse Poetic Edda and the Finnish Kalevala. Defending Bitcoin is his first solo book, bringing the Bitcoin and cybersecurity worlds together after years of work in each.

Book

One-line

Industrial-grade cybersecurity for the world's first decentralized monetary network.

Description (50 words)

Bitcoin is the first decentralized critical infrastructure for money. Defending Bitcoin treats Bitcoin that way. ICS cybersecurity professional Luke de Wolf maps the full Bitcoin threat landscape, from personal custody to network-level risks to systemic threats, and shows what individuals can do at every layer. Foreword by Mikko Hyppönen.

Description (150 words)

Bitcoin is the first decentralized critical infrastructure for money, and it demands the same layered, threat-modeled defense as power grids or pipelines. Defending Bitcoin is the first cybersecurity book written for Bitcoin from inside the discipline that secures critical industrial systems.

ICS cybersecurity professional Luke de Wolf maps the full Bitcoin threat landscape across three layers: threats to the individual (custody, privacy, physical security), threats to the network (mining centralization, node-level attacks, developer risk), and external systemic threats (regulation, grid failure, quantum, AI). For each, the book pairs the threat with concrete controls drawn from the IEC 62443 industrial-cybersecurity framework.

Written for two audiences: Bitcoiners who want to understand cybersecurity at industrial depth, and cybersecurity professionals who are skeptical of, or unfamiliar with, Bitcoin. Foreword by Mikko Hyppönen.

Sample interview questions

The book calls Bitcoin "critical infrastructure." What does that mean, and what changes when we treat it that way?
You spent more than a decade securing pipelines, refineries, and power generation. What does that lens reveal about Bitcoin that Bitcoiners typically miss?
Why apply IEC 62443, a framework from industrial cybersecurity, to Bitcoin? What does it bring that other frameworks don't?
The book splits threats into three layers: individual, network, systemic. For a typical reader, which layer should they focus on first?
You're a self-described Bitcoin Maximalist working as an ICS professional. How do those two communities react to each other when they meet?
How serious are quantum and AI risks to Bitcoin in your view, and on what time horizon?
The book argues that there is always something you can do. What's a concrete example for someone who feels overwhelmed by the threat landscape?
Mikko Hyppönen wrote the foreword. How did that come together, and what was his read on the book?
If a CISO read this book and had two minutes to decide whether Bitcoin is worth their professional attention, what would you want them to take away?
