Praise for Defending Bitcoin
Luke approaches Bitcoin the way I approach malware. He wants to understand how it actually works, where it is strong, and where it can be broken. This book applies that thinking to Bitcoin, and I have not seen it done before.MIKKO HYPPÖNENFrom the foreword · Author, If It’s Smart, It’s Vulnerable · Global Cybersecurity Expert
Bitcoin changes how we think about security, and Luke bridges that gap with clarity and precision. This is the cybersecurity book Bitcoin has been waiting for. If you care about protecting what matters in a digital world, this is essential reading.JEFF BOOTHAuthor, The Price of Tomorrow · Technology Visionary
LYN ALDENAuthor, Broken Money · Former Systems EngineerA Bitcoin book that goes above and beyond the usual, Defending Bitcoin gives the reader an actionable overview on how to use Bitcoin securely and privately.
In Defending Bitcoin, Luke analyzes the risk profile of the network as a whole, but really dives deep into how individuals can reduce their own risk profiles when using it.
TONY YAZBECKCEO, The Bitcoin Way · Senior Cybersecurity ProfessionalDefending Bitcoin is a masterful exploration of the critical intersection between cybersecurity and the future of money, providing practical, industrial-grade strategies to safeguard Bitcoin against sophisticated threats in an increasingly hostile digital landscape.
Luke de Wolf's deep expertise makes this an indispensable resource for builders, holders, and defenders of this once in a lifetime monetary revolution.
LAWRENCE LEPARDAuthor, The Big Print · Macro InvestorEvery Bitcoiner needs to read this book.
Luke lays out the security fundamentals too many of us skip past until it's too late, and he does it without dumbing them down.
I've seen firsthand how quickly things can go wrong, and I've shared my story so others don't have to learn the same lesson the hard way.
Read it before you need it.
MAX HILLEBRANDAuthor, The Praxeology of Privacy · CypherpunkEvery modern state is a printing press wired to a surveillance system, and Bitcoin is a knife pointed at both.
… Holding your own keys, running your own node, and refusing to be identified are how the knife stays sharp.
… Thanks to Luke for writing the field manual the rest of us were going to have to assemble from scratch.
