    Café Bitcoin | Yan Pritzker on Bitcoin Fork History, the September 1 Hard Fork, and Why Doing Nothing Is the Safest Move | Day 27 of 50

    Yan Pritzker, Swan's cofounder and CTO, walks his new essay on Bitcoin fork history, from the 2015 block size debates through the hard fork scheduled for September 1. Published on the Swan blog and posted to X during the show. His own entry point was Ethereum, not Bitcoin. The 2016 DAO rollback split the chain and created Ethereum Classic, and watching that taught him what a fork actually is before he lived through one in Bitcoin. Soft fork versus hard fork, explained without jargon. A soft fork produces blocks old nodes still accept. A hard fork produces blocks every existing node rejects, which means everyone must upgrade or the new chain is invisible to them. The asymmetry that decides every hard fork. Doing nothing rejects it by default. The forker has to convince every exchange, business, and holder to change software, including people asleep, on vacation, or gone. Brady's summary: they said if you're not with us you're against us, but the truth is if you're not with us, you ignored us. The block size wars were about governance, not block size. The big blockers had 58 companies, 22 countries, 83% of hash power. They still lost, because Bitcoin is not decided by a vote but by whether the blocks you produce get accepted. A 2010 forum post Yan found while researching. Jeff Garzik proposed a few lines of code to match PayPal's throughput, and 13 minutes later theymos and then Satoshi told him it would fork him off the network. The idea and the answer are both sixteen years old. The SegWit2x futures market as free-market polling. Exchanges let people trade the forked coin before the fork existed, it priced below Bitcoin, and miners used that signal. Brady: you are risking capital to vote, not answering a question on the telephone. Why every fork coin bleeds out. Holders receive it at a cost basis of zero, so selling at any price above zero is profit. Brady recounts selling his Bitcoin Cash near the intraday top around 0.4 to 0.45 BTC on Thanksgiving week 2017, watching a Telegram group call the biggest red candle in Bitcoin's history. Suze sat through six days of Craig Wright's cross-examination and describes supporters leaving court convinced he was winning. Yan's read: each splinter selects for the most willing to believe, producing what Brady calls mini cults. ⭐ The practical warning, and the reason to listen: do nothing. Replay attacks mean a transaction signed to move fork coins can be rebroadcast on Bitcoin and move your real Bitcoin. Never type a seed phrase into fork software, and treat any urgent instruction as a scam. On tail emissions: Yan grants that if Bitcoin had launched with 0.1% inflation nobody would object, because the point of the monetary policy is that it is fixed and predictable. Introducing it now is different, and he points at Ethereum changing its policy as the demonstration. His closing thought turns the whole story around. Every failed fork has proved Bitcoin cannot be changed, and the price rose after each one. He suggests this fork may mark the bear market bottom.

    Café Bitcoin | Orwellian Overreach, the Museum of Civil Liberties, and the Freedom Tech Field Guide | Day 24 of 50

    A museum for things that aren't gone yet. Roxana Nasoi of Logos walks through the Museum of Civil Liberties: five halls, twenty major events, a record kept where it can't be quietly edited. Phase one of a past, present, and future campaign. "Liberties, not rights." Roxana explains the word choice: rights imply something that can be granted and revoked. The halls cover control of money, the surveillance state, censorship, the failure of voice, and systems of control. The timing writes itself. The show aired August 14. The museum's centerpiece entry is August 15, 1971, when Nixon suspended the convertibility of the dollar into gold: fifty-five years ago, to the day after recording. Why a civil liberties project starts with money. Quoting Logos cofounder Jarrad Hope: the state offers money, property, law, identity, and governance. Bitcoin fixed the money. The other four are still hanging. Suze's Euston station moment. Talk of the surveillance state stayed abstract until a delayed train left her people-watching under what felt like hundreds of cameras. The room digs into why invisible threats only become real through shocks. KYC that doesn't stop crime. Suze lays out her case: by the Chainalysis figures she cites, under 1% of illicit activity moves through "crypto" and just 0.14% through Bitcoin, while illicit flows in traditional finance hold at 2 to 5% of global GDP, unchanged across decades of FATF rules. A rare rollback. The room welcomes this week's Treasury move to permanently end Corporate Transparency Act ownership reporting for US companies and delete the filed data: the opposite ending from the breached Liechtenstein register discussed yesterday. The freedom tech field guide. Roxana's practical stack: Umbrel home servers, mesh networks like Meshtastic that carried protests through internet shutdowns in India, mixnets like Nym versus VPNs, Faraday bags, offline second devices, and local AI. A chess app as a philosophy lesson. She built one in a weekend on Logos: Stockfish engine, real-time play, and an ephemeral chat that leaves no record anywhere once the game ends. Private by architecture, not by promise. Who adopts freedom tech before it's necessary? Brandon Quittem returns to his Myers-Briggs survey: analysts are ten times overrepresented among Bitcoiners, and maybe everyone wired to get obsessed is already here. The next wave joins by social consensus, not rabbit holes.

    Café Bitcoin | Self-Custody with Nick Neuman, Money Without Permission and Debanking | Day 23 of 50

    Suze takes us inside the UK's debanking inquiry. A director and co-founder of Bitcoin Policy UK, she's submitting evidence to Parliament's cross-party inquiry this week, and explains what an APPG can and can't do about banks blocking lawful transactions. The numbers are staggering. The Locked Out report found roughly 40% of payments to exchanges blocked or delayed by UK banks, with one exchange reporting a billion pounds in declined transactions in a single year. All legal transactions. Even the advocates got debanked. Suze's organization goes by BPUK partly because a name containing "Bitcoin" risked losing banking services. A survey found only 14% of firms successfully opened and kept an account with one of the nine largest UK banks. Nick Neuman of Casa surprises the room with a report from inside the Coldcard response: all hands taking calls for a week, helping people rotate keys, and his estimate that far more Bitcoin moved to safety than was stolen. Why multisig held up. Neuman explains why wallets requiring multiple keys haven't been swept: attackers go after single-key wallets first, and unrevealed public keys make paired devices dramatically harder to crack. The takeaway from both hosts: upgrade to multisig. Casa has been debanked twice. When Silicon Valley Bank failed, the company's Bitcoin treasury meant it could keep operating no matter what happened to the account. His advice: keep a backup bank and self-custodied Bitcoin as a stopgap. Does Bitcoin in an ETF still count? The room digs into BlackRock lowering conversion minimums into IBIT, why the conversion mostly runs one direction, and whether Bitcoin keeps its fundamental value if real coins stop circulating. Why self-custody matters to the network, not just to you. Brady walks through the block size wars: holders running nodes are who kept Bitcoin's rules intact, and concentrated custody would hand that influence to a few large institutions. Selling freedom instead of fear. Alec raises the "sovereignty multiple," the positive case for holding your own money, and Suze describes orange-pilling her beautician by paying in Bitcoin: adoption through use, not through warnings. Lebanon, El Salvador, and Liechtenstein. Suze's reporting tour: what a country looks like after banking trust dies, holding two ideas at once about El Salvador, and a breached ownership register as the case against data honeypots.

    Greg Foss on Bitcoin as Insurance, Credit Signals in the AI Boom, and Do the Math | 50 Days for Freedom, Day 22

    Greg Foss is back. After stepping away from Twitter and spending time on Nostr, the veteran credit analyst explains what pulled him back: young people reaching for socialism, and credit markets he sees as far less healthy than equities. The credit default swap thesis. Foss walks through his method: take the CDS spread on U.S. government debt, multiply by total obligations including unfunded liabilities, then compare that to Bitcoin's market cap. He flagged his spread number as from memory. Why insurance, not a risk asset. Most holdings are short volatility: when volatility rises, they fall. Foss argues Bitcoin should do the opposite, and credits BlackRock's Larry Fink as one of the few in traditional finance framing it that way. The rate the Fed does not control. Warsh has suggested AI productivity gains leave room to cut. Foss points instead to the 10-year Treasury, set in the open market, which could rise if investors demand more for U.S. credit risk. Credit markets are flashing before equities. A listener asked about widening CDS spreads across AI infrastructure names. Foss compared NVIDIA's vendor financing to Nortel and Lucent in 2000, and pointed to CoreWeave's tight debt service covenant. Banking is a leveraged business. From inside an insolvent Bank of Boston in 1992, Foss saw the math up close: roughly $5 of equity behind every $100 loaned. He argues Bitcoin can act as a safety net against that fragility. Bitcoin mining versus AI data centers. Miners can switch off in seconds and chase stranded energy; AI workloads cannot. Suze raised UK curtailment spending and ERCOT's grid balancing record, and asked whether mining gets built into AI sites. What the ETFs changed. Foss says a Wall Street wrapper was necessary for institutional allocation, while raising the paper Bitcoin question. He runs a 5% of global assets thought experiment, stressing he is not certain it happens. Treasury companies as an evolution, not an endpoint. Foss says he admires Michael Saylor without admiring every lever pulled, notes the premium to underlying Bitcoin has collapsed toward parity, and expects these vehicles to matter less over time. Bitcoin as collateral, and pensions inching in. Foss calls Bitcoin pristine collateral and a natural extension of lending. Dom described recommending it to pension boards years ago and pointed to a Michigan 13F filing adding to its position.

    Café Bitcoin | Larry Lepard and Greg Foss on Japan as the Seminal Event, Credit as the Warning, and Why Timing Beats Everyone | Day 21 of 50

    Cory's argument about narratives. Journalists and bankers keep asking what the catalyst will be, but narrative follows price rather than causing it. Something moves because sellers are exhausted, and the reason gets fitted afterward. The only narrative that matters is Bitcoin being better money for eight billion people. Larry Lepard on what actually moved. The debasement trade began in earnest last year, and it showed up first in gold and silver rather than Bitcoin because those are more widely understood. Silver quadrupling is the kind of thing that has essentially never happened before. Japan is the seminal event. With Japan holding roughly $1.2 trillion in Treasuries, the US offered swap lines and rotated euro reserves into yen. What shook the gold market was the Treasury Secretary suggesting the existing facility should be larger. As Larry put it, a swap line is printing money, full stop. A guest correcting his own AI. Larry noted the press had the facility's usage wrong and that AI had misled him too, so he went and read the Fed's own statements to establish it had not actually been drawn on. Worth noting as a method, not just a detail. The 1992 parallel, corrected live. It was Warsh, not Bessent, who worked for Soros attacking the Bank of England. Thirty-four years later he is on the other side of that trade, in the Bank of England's role. Larry's thesis for the year is the unmasking of Warsh as a hawk, because the math will not let him be one. The Fed has exactly two tools. It can mislead about inflation, and it can print. Larry's read is that we are currently in the first phase and last week signalled a move toward the second. He also explained yield curve control as what governments do when the bond market stops cooperating, with the post-war precedent as the template. His own record is the caveat he volunteers. He expected massive inflation out of 2008 and a cascade from Silicon Valley Bank, and was wrong both times. The people running the system are good at kicking the can, so the honest position is direction with no date. The two-tier system he expects. The dollar remains the unit everyone transacts in, gold displaces Treasuries as the reserve asset, and Bitcoin sits alongside before eventually supplanting gold over years, not days. It is already visible in oil sold for yuan and immediately swapped into physical gold. Greg Foss on where trouble announces itself. Every recent crisis began in credit rather than equities, and private credit is where he is watching now. His trader's version: equity investors ask how much they can make, credit investors ask how much they can lose. Credit is the first smoke in the theatre. And his structural objection about treasury companies. He takes issue with perpetual preferred shares being described as credit, because a perpetual has no maturity and no principal repayment, so its running yield cannot be compared to a bond's yield to maturity. Retiring that stack at scale would mean selling Bitcoin, which was never the strategy.

    Café Bitcoin | Jeff Ross on Energy Money, Why Abundance Still Needs Scarcity, and Study Before You Stack | Day 20 of 50

    The theme was looking forward After two brutal weeks the room turned to what comes next, set up by a listener's observation that the philosophical Bitcoin conversation which drew people in around 2020 had gone quiet for years and is audibly back Why the guard dropped Phillip framed Coldcard as a psychic blow because it was the standard for personal sovereignty, and the harder question is why the surrounding behavior got a pass. Isaiah added that a friendly administration lulled people into "we've arrived" and a foot off the gas Suz's line is the sharpest in the episode "I don't tell people to buy Bitcoin anymore. I tell them to study it," because only genuine understanding stops someone panic-selling an eighty percent drawdown And she named the drift Keep Bitcoin separate from the leverage games and financial engineering, and drop the hero worship and Wall Street cheerleading, particularly among people who pride themselves on critical thinking Dice rolls may not be the destination Swan engineer Steve is unconvinced that rolling your own entropy is the paradigm going forward, citing Luke Childs' time-locked proposal as proof that one week of focused attention already produced something worth exploring Jeff Ross on why he came back He left in 2024 at what he called peak clown world and returned because the Overton window moved and macro conversation had vanished from Bitcoin rooms. He was emphatic that nobody should follow him and that nothing he says is advice Energy money, his signature thesis The dollar began as commodity money redeemable for gold, and Bitcoin is commodity money whose commodity is energy itself. Tesla, Ford and Buckminster Fuller all reached for the same idea, and proof of work is what makes it real He rejects the abundance argument flatly Told money may not matter within fifteen years, he called that top-of-hype-cycle talk most often heard during fundraising. Sunlight is free but panels, batteries and rare earths are not, and economics will always be economics Cory on the only real asymmetry Strategy is legible to him and operations are not, but cryptography is the one thing genuinely on our side: the ability to make something unbreakable by an adversary with millions of times more power. His conclusion is that early-nineties cypherpunks may turn out to be the pivotal figures How both guests actually cope Jeff sees an eerie replay of the 1930s and admits a libertarian may not fit where this is heading. Brandon Quittem urged empathy for those with no stake in the system, citing Naval that societies coordinate by free market or by force. Both landed on going outside and thinking local

    Café Bitcoin | Slay Your Heroes, the Fourth Turning, and Certainty Lowers Your Guard | Day 17 of 50

    Suze's Forbes piece, and the question under it. Her Telegram reporting found a persistent identifier that survives restarts, network changes and borders, with the credible risk being targeted surveillance rather than mass tracking. Her real question: why is don't-trust-verify never applied to companies and personalities inside Bitcoin? The confessions, and Cory's calibration. American HODL admitted he bought a Coldcard largely as a badge of Maxi Club membership, and Odell described being pulled into a cult of personality. Cory's distinction: someone who bills himself as a technical expert and reviews products carries responsibility a self-described bullshitter does not. He also warned against the new bad heuristic. Treating abrasiveness as a proxy for bad code fails immediately: Core and Blockstream are full of people who read as cocky and their code is sound. He credited NVK as a genuinely good educator while calling the outcome inexcusable. Brandon Quittem: deep in it, not at peak. Maximum wealth inequality is a classic Fourth Turning signpost, and the post-war institutions are a shell of themselves without anyone needing to be malicious. He held his own confidence low throughout, calling the framework a rough way to squint at the world. His bet on the climax. Not a head-to-head with China, which a hyperglobalized economy makes unlikely, but a Cold War 2.0: proxy and economic war, trade policy, supply-chain fights, plausible deniability, and zero-day attacks on each other's infrastructure. AI through the Fourth Turning lens. The authors would say technology is always arriving and the variable is how the generational mood receives it. Facebook landed because millennials were the sharing archetype; Gen X would have refused it. He calls AI pure leverage with no clear direction. Horseshoe theory, and Bitcoin as the through line. Answering Suz on where left and right even are now: both extremes arrive at authoritarianism from the same wealth-inequality catalyst, which is why Bernie and Trump were popular at once. Bitcoin is what pushes back on both. He retracted his own timeline live. Five years ago he would have called a Bitcoin standard likely by 2030 and now says that was far too aggressive. A First Turning looks like exhaustion, inequality easing, culture getting more boring, and it may only be visible in hindsight. The libngu decision, traced. An audience question surfaced that the firmware was rewritten off a GPL library partly out of anger at being cloned, producing an in-house source-available replacement and fewer eyes. Of 300-plus repos the red team has scanned, the one that came back completely clean was libsecp256k1. The synthesis, and the way out. Suz: Bitcoiners who believe they saw through the system struggle to admit deception, because it means admitting they were fooled. Brandon: that lowers the guard rather than raising it. His prescription is local, not global. Be the sewer rat yourself.

    Café Bitcoin | Guy Swann and Yan Pritzker on Coldcard, the Asymmetry of Defense, and Privacy | Day 16 of 50

    Guy Swan on learning the wrong lessons. The takeaway circulating is "go with the biggest company," which forgets Mt. Gox and FTX and everything else proving size is not safety. His analogy: when a libertarian politician betrays you, libertarianism didn't break, you got scammed. He wants a rule that works forward. His sharpest point: "I don't want a rule that only works in hindsight." Anyone can now point at the source-available license. The useful question is what indicator predicts the next failure before it happens. His own heuristic broke in both directions. He had trained himself not to dismiss builders for being abrasive, and now concludes that for security specifically, a maintainer who attacks people reporting problems is telling you something. Yan Pritzker paired it with the engineering version: without a culture of safety, people stop surfacing mistakes. James O'Beirne's tripwires. He seeded wallets on-chain carrying graduated entropy over broken Coldcard seeds, five dice rolls, ten, fifteen, one and two-word passphrases, as bait. The bare seed was swept within an hour and nothing else has moved, mapping attacker capability live. The red team's numbers. Rob Hamilton and Calle have scanned over 300 repos and spent roughly $40,000 on tokens in two days, finding critical vulnerabilities at about one per person per hour. OpenSats is now funding most of that budget. Every company needs an agentic security pipeline. Yan's argument: agents are non-deterministic, so one scan proves nothing. The real work is harnesses that find, test, distill and reproduce on a loop. Swan has been building this for six to twelve months. The asymmetry is the whole problem. Attackers need one vulnerability, defenders need all of them, and the economics favor the attacker. Some have been paying up to 90% of stolen funds in fees to get transactions mined quickly. A fake Coldcard desktop app is circulating. No such application has ever existed. Trezor reported a phishing spike since disclosure, and a counterfeit Wasabi wallet reached an app store. Nobody legitimate asks for recovery words, and unsolicited migration instructions are always hostile. Yan's read on whether this repeats. He calls the bug exotic: entropy wasn't weak, it was switched off entirely. Scans across the popular hardware wallets show correct and consistent entropy use, so he thinks this specific failure is unlikely to recur elsewhere. Government overreach, the other half of the show. Suz on Liechtenstein's beneficial ownership register, roughly 31,000 entities, built in 2021 for EU anti-money-laundering compliance and now breached and offline. Yan on the Bank Secrecy Act's 1970 threshold, never inflation-adjusted, capturing dramatically more data for near-zero measured effect.
