Last Notes npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Legit, credit to Nifty for letting him speak on the topic. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Yes... Because it's our podcast. Not his. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I don't work for Knut. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I draw the line at personal insults. You do that, you're just a troll. GTFO. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Fuck off, troll. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I see zero actual harms from 110. A couple of niche use cases will need redeveloping. No risk to being able to self custody or send Bitcoin for normal users. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf It was more inertia than anything. I had my node running the 110 client, and I knew I could always change versions later. To a certain extent, I was just waiting and watching. Then my node actually stopped responding, and I needed to wipe and reinstall to get it back up. That took longer than I expected, and by the end of it I had reasoned my way back to 110 support. Sorry for any offense, it wasn't intentional. It was more of an anecdote that I had never turned the signal button off. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf This is taking "value is subjective" to an absurd place. Bitcoin isn't for everyone's meaning. It's for money. The protocol already has rules. More rules is fine. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Yes :) npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I'm live on Stacker News right now! https://stacker.news/items/1524157 Ask me about Bitcoin cybersecurity, BTCHEL, BIP-110, or anything else! npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Join me in a few hours and AMA! #nevent1q…ruw0 npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Tldr since the Guy interview: I find 110 activating smoothly to be the least risky and least chaotic scenario. I was getting the game theory steps a bit wrong. Something longer coming when I have time to write everything down. Also a few more pods. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Apparently you haven't kept up with my X. I should really make an update on both platforms. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf There is no reason for this. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I mostly see Luke as committing to forking off to an altcoin if 110 doesn't work. That profoundly saddens me. This all-or-nothing talk is part of the problem. I will be happy if 110 succeeds but I just don't see it happening. I believe now that the incentives are the inverse of what they should be. And the result will be that a large portion of the monetary maximalists leave Bitcoin. And maybe there's even a protracted chain split and a competing coin. I can't support that outcome. Maybe I'm overvaluing the tail risk, but that's sort of my job. If I'm wrong, I'm wrong. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Knots on StartOS, mining with OCEAN using DATUM. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Apparently the IBD has been improved significantly in recent Core releases. Not just assumevalid. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf This bot account is a deranged moron who apparently thinks I'm pro spam. GTFO. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf You've given me lots of food for thought. I'm not saying I'll change my position. But if I do, it will be final. Still a little ways to go yet. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf The vast majority of Bitcoin users have no idea BIP110 is even happening. Disruptions to the ability to use Bitcoin as money should be avoided. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf This fellow is reply-guying me elsewhere too. Seems to have a specific issue with me. Oh well! npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf No, idiot. A perfectly valid transaction could be mined by a non-110-signalling block and then it's in limbo. If it gets mined by the BIP-110 chain, it will be in a totally separate block with separate history, which may have downstream effects. But the BIP-110 side could also get RBF'd, permitting a double-spend. Think things through before posting. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I content myself knowing that you're completely wrong. Feel free to point out why you think my book is "AI slop". If you don't want to do that, kindly fuck off. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Thanks for the feedback! I'm actively considering my position on BIP-110. If forced to pick between "pro" and "anti", I'm currently "anti", but there's a lot more nuance. I'm mostly focusing on the downside tail risks. Maybe I'm overweighting that scenario. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Disagree. If a user's transaction gets mined in a non-compliant block, that transaction will be in conflict. Double spending will be possible on the margins. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Thanks, I appreciate that! I came to my position through writing Defending Bitcoin. I wrote a risk management book. I evaluate the risk of profoundly negative outcomes if BIP-110 causes a chain split to be too high. Frankly, my real position might be that I support it after all (because I still mostly support the changes, I have specific technical objections that aren't direction ally important), but only if those signaling/enforcing drop it immediately if it looks like it's going to end up with a tiny minority of hash rate and just fork off. In other words, try it, see what the outcome is, but don't cling to a dead-on-arrival fork if that's the result. I believe Bitcoin will survive with or without BIP-110. The "with" scenario would be truly positive in my view. A user-activated rebuke of both arbitrary data and the prevailing governance structure. I'm all for that. The "without" scenario is what I'm worried about. I don't want all the monetary maximalists to leave if this soft fork fails to activate and become the longest chain. I don't think making this an all-or-nothing effort is right. And, in the case of failure, there will be much gloating from on high and ridiculing of those who prefer less arbitrary data on Bitcoin and are uncomfortable with Core's governance. In Defending Bitcoin itself, I don't even say "don't support BIP-110." I highlight the potential risks of a chain split, and say DYOR. Know what you're getting into. At this point, I see that the momentum for BIP-110 is absolutely there. Almost half the plebs I met at BTC Prague said they were pro-110 or considering supporting it. The only opposition I heard was from devs. But there are also smart people in the space who support its goals but don't think it will activate. I'm in that camp too. I don't know how to square these positions. My internal schelling point landed on not supporting BIP-110, but I'm not sure that's totally accurate anymore. Perhaps more accurate would be that I support trying, but giving up quickly if it fails. The problem is that we're dealing with individuals. I have a feeling or even know that many people will either continue to support the minority chain or just give up on Bitcoin entirely. This is kind of a chicken and egg problem now. If it's going to happen anyway, does my support or non-support make any real difference? Either way, come August 7th, I'm still going to be here. And dealing with the fallout of BIP-110 being unsuccessful, if that's the case. I don't know if that clarified anything for either of us. But those are my thoughts. Take them as you like. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf See here. #nevent1q…mjyj npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Look at any of my highlighted X posts, listen to any of my recent podcast appearances, or any Bitcoin Infinity Show / Feeedom Footprint Show from about the middle of 2023.

That's why I'm not supporting at this point. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Care to tell me why you think that?

This one is from my career defending the industrial systems that keep the world running. Industrial control systems are the computer and network layers running physical processes. Power plants. Water treatment facilities. Pipelines. Factory floors. When one of these systems gets hit, it's not a website that goes down, it's a real-world process that stops or fails in a way that can hurt people. Defending these systems is a different job from defending a website. The IT side of cybersecurity can usually patch on a schedule and tolerate a few minutes of downtime. The operational side often can't, because the plant has to keep running, and any unplanned stop has real consequences. The two sides optimize for opposite things. Chapter 4 walks through the architecture, the controls, and the culture of this critical infrastructure security. How a plant gets organized into network zones so a single compromise stays contained. How we organize security controls into categories, and use security levels to scale them up to resist a determined nation-state. How the IT and OT mindsets converge when you have to defend something that absolutely cannot fail. This is the framework the rest of the book uses. Every threat chapter in Part II uses the ideas and vocabulary from Chapter 4. Next, we see how it all connects and applies to Bitcoin. https://blossom.primal.net/4a793f17c29fa6f73116f2e9d264f950739c4f227c80746716dd0e1d3530e393.jpg npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Chapter 4 of Defending Bitcoin - Industrial Control Systems and Securing Critical Infrastructure.

Chapter 3 walks the core concepts the rest of the book runs on, in plain language. It opens with the CIA triad (just a coincidence, I promise!), the three properties cybersecurity defends in every system. Confidentiality keeps information from anyone who shouldn't have it, integrity keeps it from being altered without authorization, and availability keeps it reachable for the people who need it. Every threat in Part II maps back to one of those three. From there it gets into threat modeling, which is a structured discipline rather than a vibes-check. Before you defend anything, you ask who the adversary is, what the asset is, where the attack surface lies, and what the mitigation looks like. Run that formally and some threats turn out to be less important, while others turn out larger than you'd expect. Then comes defense in depth, which is just the principle that you never lean on a single control. You layer them so each one stands on its own, and a failure in one doesn't cascade through the rest. The chapter walks how to design those layers so the whole system doesn't unwind from a single point. We also formally define the concept of risk, measured as likelihood times impact. A threat that's devastating but unlikely calls for different controls than one that's common but survivable, and that matrix is how Part II keeps everything in proportion. Without it, the threat chapters that follow would read like a long list instead of a prioritized map. By the end, you've got the cybersecurity vocabulary that the rest of the book depends on, and the bridge from "I hold Bitcoin" to "I'm responsible for defending a system I have a stake in." npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Write a review on Amazon if you've read and liked Max's book!

Bitcoin — The Hardest Money Ever Made. This chapter walks the case from first principles. Scarcity that can't be debased. Verifiability without trust. Ownership without anyone's permission. A supply schedule fixed in code and enforced by every node. It's my distillation of Bitcoin's monetary principles. This chapter will be familiar reading for most bitcoiners, but it gets us all up to speed. For the technical reader who is approaching Bitcoin for the first time through this book, it's an introduction to Bitcoin as money. https://blossom.primal.net/9d796eb8a9330f4516132074f35b75038908eb4b192cd863b861684dfa85039a.jpg If you want to read Defending Bitcoin right now, sign up for an advance copy below.

Between now and then, I'm going to preview what's inside, one chapter at a time. Chapter 1, Bitcoin: The Decentralized Protocol. I had to make a choice with the opening chapter. Start with the monetary features, or start with the protocol. I went with the latter, because I figure that technical non-Bitcoiners (such as those who might read a cybersecurity book) might be more comfortable with the technical side of things. So, Chapter 1 walks the protocol from first principles. Nodes, miners, the mempool, the difficulty adjustment. The architecture of decentralization. Building up the how before getting to the why. Bitcoiners get a refresher. The dual-track approach runs the length of the book.

Can't stop the things from getting out into the wild. Warning against doing stupid things is one of the only forms of recourse. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Yes. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I think this falls into the category of just because you CAN do something. doesn't mean you SHOULD. Nobody should use this, IMO. But, like many things, looks like it's getting built. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Look inside my upcoming book, Defending Bitcoin: Industrial-Grade Cybersecurity for the Monetary Grid 👇 https://blossom.primal.net/678ab8b5ca6800770239bcce042d3fcbcd19e431cc144c599f5d379c2c149e4f.png First, the Foreword by Mikko Hyppönen. One of the most widely-respected figures in cybersecurity with his own take on Bitcoin. I'm grateful that he agreed to contribute his view to the Defending Bitcoin! Next the Introduction. My story of how I started in the Industrial Controls sector, then found Bitcoin, and merged the two worlds. Also goes over the format of Defending Bitcoin. Part I is the introduction to Bitcoin and Cybersecurity, forming a basis of vocabulary for readers familiar with either or neither subject. Chapter 1. Bitcoin — The Decentralized Protocol All about Bitcoin the technology, written for technically-minded readers who don't know about how Bitcoin works. Chapter 2. Bitcoin — The Hardest Money Ever Made All about Bitcoin the money. What makes Bitcoin's monetary properties different from every other money in history. Chapter 3. Cybersecurity Fundamentals — The Universal Shield The vocabulary of cybersecurity based on industry best practices. What is risk, what are threats, vulnerabilities, controls. Everything we need for the rest of the book. Chapter 4. Industrial Control Systems and Securing Critical Infrastructure How critical infrastructure is defended differently from traditional cybersecurity. Includes a primer on industrial control systems and critical infrastructure so my the comparison to Bitcoin makes sense. Chapter 5. Bitcoin as Critical Infrastructure — The Monetary Grid The core thesis, that Bitcoin is the first decentralized critical infrastructure for money and should be defended the same way we protect power grids, pipelines, and factories. Part II is the Bitcoin Threat Landscape. 10 chapters of threats on an individual and network level, and what we can do about them. Chapter 6. Exchange and Custodial Failures From Mt. Gox to FTX, why custodial Bitcoin keeps blowing up, and what that means for your stack. Hint: the answer is to get your Bitcoin off the exchanges and into self-custody. Chapter 7. Securing Your Bitcoin: Personal Defense of the Private Key The full personal custody chapter, covering hardware wallets, multisig, seed phrase handling, and inheritance. You have the responsibility to secure your Bitcoin. Learn how here. Chapter 8. Privacy, Physical Security, and Staying Safe Privacy on-chain, OPSEC off-chain, and maintaining your physical security when people know you own Bitcoin. Huge shoutout to the excellent Praxeology of Privacy by @nprofile…8p0e , read that after this chapter. Chapter 9. 51% Attacks and the Decentralization of Mining What a 51% attack would actually look like, why mining concentration is important, and how decentralized the hashrate really is. Includes practical steps to do something about it, as always. Chapter 10. Node-Level Threats and Client-Side Defenses Everything to do with the security of your node, including all the work being done to secure Bitcoin node software, and what they defend against. Run a node, stay secure while you do. Chapter 11. Arbitrary Data and Witness Abuse An overview of ordinals, inscriptions, and arbitrary data. You may not think these are a problem. I lay out why it's a cybersecurity issue and makes Bitcoin worse as money. Chapter 12. Governance Risks. An honest examination of the risks Bitcoin faces from development centralization, and what can be done about it. It's not one-sided, though. I also cover the risk of changing Bitcoin, especially without wide consensus. Chapter 13. Political and Regulatory Threats Bans, surveillance, KYC, and mining restrictions, plus the realistic ways Bitcoin survives state-level pressure. Chapter 14. Grid and Network Failures: Keeping Bitcoin Alive Offline What happens when the grid goes down or the internet gets cut, and how Bitcoin stays alive offline through mesh networks, radio, and satellite. Chapter 15. Emerging Threats: Quantum and AI Full coverage of the latest developments of Bitcoin and Quantum. No FUD, but it's not something we should ignore. Also includes coverage of AI as it affects everyone more and more these days. Conclusion We end summarizing everything together, and it's optimistic! Defending Bitcoin isn't about doom and gloom. It's about knowing what's out there, and finding out what you can do about it. There's always something you can do. Always. Appendices Included in the print book are glossaries of cybersecurity and Bitcoin terms, and a section of recommended reading across all topics. Further resources are available on defendingbitcoin.com, including a threat model worksheet where you can find out how the threats in Defending Bitcoin apply to you. No data collection, I promise! You can see more about the book at the Look Inside page, including the full foreword, introduction, and previews from two chapters. https://defendingbitcoin.com/read Reminder, Defending Bitcoin will be available on Amazon and bitcoininfinitystore.com from June 15th, and the first physical copies will be available at @nprofile…py4c - come see me there and get a signed copy! npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Worth exploring, Joe. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf What is the reason to do this?

Looking forward to your thoughts. npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf It is a Bitcoin maximalist perspective. Although it's really simply a Bitcoin perspective. Other cryptos are essentially not covered at all. Some of the security practices will absolutely apply universally. I appreciate your offer to buy with Monero, but I only accept Bitcoin (and dirty fiat). npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf Thanks a lot for the support, Max!

Thanks for all your support! npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf You can hear me tell @nprofile…3hw8 all about it on the latest @nprofile…k3zk on Fountain: https://fountain.fm/episode/xRzrZHRj9fRDqf3UI3EW npub1fk8h6g8zhftw8c7pga2zjd84p2z949up5lc3qdchm9v4m0q7mwws7jcwld lukedewolf I've been a bit absent from Nostr for the last little while, but that's about to change. For the past few months, I started focusing on a new project, and I'm finally ready to announce what I've been up to. I've written a book. Defending Bitcoin: Industrial-Grade Cybersecurity for the Monetary Grid. 6 months ago, I realized how I could apply my cybersecurity background to Bitcoin, with a perspective grounded in the world of critical infrastructure and industrial control systems. In Defending Bitcoin, I make the case that Bitcoin is critical infrastructure, and I mean that technically. Critical infrastructure is everything essential for the modern world to run the way it does, and I assert that Bitcoin meets the threshold of that definition. Defending Bitcoin is grounded in the industrial cybersecurity principles that I use on a daily basis. The framework I've built is based on ISA/IEC 62443, the most widespread industry standard for industrial cybersecurity, and applies universal cybersecurity principles such as defense-in-depth, risk management, and threat modeling. And in all cases, there's always something you can do to improve your security or that of the network as a whole. I wrote the book for two audiences at once. The first is bitcoiners who want to improve their security posture. The second is technical professionals who may be skeptical about Bitcoin and want to understand it better. I build a base of vocabulary for both sides to understand each other, then cover the threat landscape over the course of 10 chapters. Launching today is the accompanying website, https://defendingbitcoin.com/ where you can get a preview of the book, read endorsements from Mikko Hyppönen (the foreword writer), @nprofile…w2ua , @nprofile…u7e3 , @nprofile…h4hk , @nprofile…8p0e , and @nprofile…cqdh . I've also built a threat modeling tool where you can check how the book applies to you (fully local, we don't collect any data except your email address, if you want updates). Defending Bitcoin will be available for purchase online on June 15th, right after @nprofile…py4c where I'll be debuting the book physically. Use code DEFENDINGBITCOIN for your ticket, and come see me in Prague to get your signed copy! I'm thrilled to be releasing this book because it's truly the best possible contribution to the space that I can make. I managed to find a way to bridge the two worlds I live in, those of my day job in cybersecurity and Bitcoin. I hope you find the book to be a helpful guide to improving your security, and that it makes a positive impact for Bitcoin as a whole. I'll be posting more often about the Bitcoin cybersecurity topic, and hopefully that's valuable as well. I'm looking forward to hearing what you think! https://blossom.primal.net/678ab8b5ca6800770239bcce042d3fcbcd19e431cc144c599f5d379c2c149e4f.png
