Luke de Wolf, industrial cybersecurity expert and author of “Defending Bitcoin”, applies critical infrastructure security frameworks to Bitcoin itself. We dig into the network's real risks and vulnerabilities: arbitrary data, Bitcoin Core's governance structure, and the Core vs. Knots split. Luke’s argument: Bitcoin has weathered this so far, but complacency is the one risk it can't afford.
