The Great Hackening of 2026
In this Take episode, I break down the “Great Hackening” ripping through Bitcoin right now – from Coldcard’s catastrophic entropy bug to Liquid’s recent 4,000 BTC exploit, Lightning implementation issues, and a few major wallet update and data breaches. I also explain how AI has completely flipped the economics of attack and defense, why Bitcoin is the canary in the digital coal mine, and what practical steps you must take to protect your stack. This episode is a roadmap for surviving and ultimately benefiting from this brutal security stress test.

How Does Bitcoin Self Custody Recover From This? (Coldcard Q&A P3)
In this third Coldcard Q&A, I tackle entropy, device trust, DIY signers, and why I’m leaning harder than ever on multi-sig. I walk through why understanding encryption must become a mandatory survival skill, rather than a niche hobby, if we want to resist a dystopian future. I also share where I moved my personal stack, explain how multisig actually saved me, and explore the impossible ethical nightmare of white-hat hackers trying to rescue compromised wallets.

Roundtable_024 - The Aftermath
The roundtable is back, but we're missing a familiar face. Mechanic has officially stepped down from Ocean, so it’s just Jeff, Steve and I digging into the aftermath of BIP110, from why the soft fork failed to what Luke and Mechanic’s departure means for Ocean and Bitcoin Core’s influence. We debate whether the real existential risk is block-template centralization, how much BIP110 helped or hurt Knots and Ocean, and why some of us think the strategy overplayed its hand. We close with a wild proposal to pressure Coinbase into proving reserves using their wrapped BTC token, and what true Bitcoin “bank runs” might look like in the future. Chapters - Introduction - The BIP-110 aftermath - Mining decentralization versus spam filtering - Tapscript, OP_IF, and breaking consensus rules - The importance of Stratum V2 and block templates - Mining economics on the BIP 110 fork chain - The Coldcard incident and state-sponsored attacks - Force proof of reserves on Coinbase - The Great Consensus Cleanup - Ron Paul, stepping stones, and sound money Guest Links Steve Simple Nostr (Link: https://tinyurl.com/3s6a8yn8) Steve Simple on X (Link: https://x.com/stevesimple) Jeff Swann Nostr (Link: https://tinyurl.com/3sjc3bcp) Jeff Swann on X (Link: https://x.com/agoristview) Affiliate Links Become sovereign, hold your keys, be censorship resistant with the Bitbox hardware wallet.

Was it all a "Retirement Attack"? (Coldcard Q&A P2)
In this episode I continue unpacking the Coldcard RNG disaster, wrestling with whether it was malicious or just shockingly incompetent design and attitude. I walk through how arrogance, licensing changes, and convoluted security theater may have let a fundamental failure sit unnoticed for years, possibly causing key collisions and bizarre “free Bitcoin” situations. I also warn about fake Sparrow and Wasabi mobile apps ruggedly stealing funds from people scrambling to move their funds, and set up a part three focused on lessons learned and best practices.

Is Rolling Your Own Entropy The New Standard? (Coldcard Q&A P1)
In this Guy's Take, I walk through listener questions and comments on the Coldcard random number generation failure and what it really means for Bitcoin self-custody. We dig into why the RNG bug went unnoticed for years, the difference between source-available and truly open source hardware, and how dice rolls and strong passphrases change your threat model. I also share how I’m thinking about safer setups going forward.

Chat_178 - Our Burden To Carry with American HODL, Erik Cason, and Brandon Quittem
***"In the early days, the average user could probably use a Coldcard and know the amount of entropy required. The average Bitcoin user today, no clue. And so the times have changed, our message should have changed. And where I come down to is essentially what you said HODL, you should custody your bitcoin at the level that you are ready for. And that is a process. Day 1, don't shame someone for using an ETF. Applaud them for exposure and remind them that this isn't the end and as your experience, your knowledge, your position size increases, you may want to change that custody model and that's okay." ~ Brandon Quittem*** Today, I'm sitting down with American HODL, Erik Cason, and Brandon Quittem for a conversation that swings between total despair and genuine optimism. We are facing a massive reckoning in the Bitcoin space right now. The recent Coldcard exploit and other vulnerabilities have shattered a lot of illusions. And frankly, we misled a lot of newcomers into thinking self-custody was easy. The fallout has been tragic for many who lost their savings. In this chat, we confront the uncomfortable truth about toxic maximalism, groupthink, and the arrogance that led us to trust blindly. But it's not all doom and gloom. We discuss the practical tools we have at our disposal today to build real resilience. We debate the true meaning of self-custody, why holding ETFs isn't a sin, and how local AI models can actually help you harden your setup. The stakes are simply too high to keep relying on bad heuristics. You need to hear this if you want to protect your stack and your family from what's coming next.

Learning the Wrong Lessons
Thousands of careful Bitcoiners just got wiped out by a Coldcard entropy bug, and I use this episode to push back hard on the idea that self-custody is dead, and "don't trust, verify" failed us. I walk through the brutal history of centralized custodial failures, explain why "holding your own keys is still orders of magnitude safer, and extract three real lessons from this recent disaster. This is about keeping perspective, learning the right lessons from pain, and making Bitcoin self-custody stronger, not weaker. Chapters - Intro - Is self custody pointless - Only tradeoffs exist - History of exchange hacks - Custodial total losses - Not your keys - Coldcard loss in context - Bitcoin as antifragile - Open vs source available - Audits and entropy Affiliate Links Become sovereign, hold your keys, be censorship resistant with the Bitbox hardware wallet.

Chat_177 - Security Is Just a Hard Problem with Lloyd Fournier
***"I think that self custody is not going to be dead. I think that there is going to have to be a group, a vanguard of people that do this and take it seriously. The revolution won't work without that. Everything under the spectrum is acceptable. But if you know what you're here for, you got to put pressure against those systems. And that is by taking the self-custody yourself. That's why we make tools for those people." ~ Lloyd Fournier*** Self-custody is not dead, but it is a ridiculously hard problem to solve. And recent events have proven that hardware wallets are not the infallible fortresses we sometimes pretend they are. I sat down with Lloyd Fournier, the cryptographer and architect at Frostsnap, to talk about what it actually takes to secure your Bitcoin when you can't even trust your own devices. We get straight to the weeds on how Frostsnap is rethinking multisig by using Shamir secret sharing to sign transactions without ever reconstructing the private key in one place. But we also tackle the elephant in the room: the recent Coldcard entropy vulnerability. Lloyd also explains exactly how the Dark Skippy attack works, why bad random number generation is fatal, and why hardware wallet manufacturers are ultimately trusted third parties. We also shift gears to talk about alternative cryptography, and the magic of BLS signatures and why they completely remove the need for randomness during signing. And of course, we had to address the quantum computing threat. Is the danger real, or is it mostly academic noise? We debate the best way for Bitcoin to safely migrate if quantum computers ever actually materialize, including a really clever idea for a quantum canary bounty. This is a must-listen if you approach self-custody with an adversarial mindset. Chapters - Introduction - Lloyd Fournier's background and building Frostsnap - Why software is a multisig single point of failure - Dark Skippy and hardware wallets attacks - Breaking down the Coldcard entropy vulnerability - Why self-custody is mandatory for Bitcoin - BLS signatures and removing randomness from signing - The quantum computing threat - Soft forks and quantum canary bounties - Hash-based signatures and stateless cryptography - Red teaming hardware wallets using AI models - Why everyone must eventually learn self-custody Guest Links Lloyd on X (Link: https://twitter.com/LLFOURN) Frostsnap on X (Link: https://twitter.com/FrostsnapTech) Frostsnap's Website (Link: https://frostsnap.com/) Affiliate Links Become sovereign, hold your keys, be censorship resistant with the Bitbox hardware wallet.
