This is insane. This is INSANE. This is a blatantly obvious sign of the impending doom of the U.S. Dollar and all fiat currencies. Here's the situation: The United States Treasury issues bonds and other investment securities. They call these, “treasuries.” The U.S. Treasury issues treasuries when the U.S. Federal Government spends past its budget, resulting in a “budgetary deficit.” The sale of treasuries makes up for the loss. The treasuries are sold and tacked on as debt. This is the substance of the big $40 trillion debt number in the United States. Key point: The U.S. Federal Government has been in a budgetary deficit in 51 of the last 55 years, with the last surplus year being in 2001. Here's how it actually plays out: A year passes. The government spends too much money, creating a budgetary deficit. The government finances that deficit by selling debt (in the form of treasuries). The government receives money to cover its spending, and tacks on the sold debt to its debt total. Next year comes around. The government spends too much money again, creating another deficit. Same mechanism... government sells debt, receives money, and tacks on more debt. But there's an issue. Old debt is coming due. But the government doesn't have the money to pay for it - it has been spent. What does the government do? It issues new debt to pay off the old debt. Round and round this goes, year after year. This is how the government operates. Key point: The U.S. Treasury, which is part of the U.S. Federal Government, has to sell new debt to new investors to pay off the old debt from old investors. This is because of 1) the constant budgetary deficits and 2) the debt from years past coming due. Key point: Given that the definition of a Ponzi scheme is, “An investment scheme where new investor money is used to pay off old investors.” …The U.S. Federal Government is running a Ponzi scheme. To the tune of $40 trillion, and counting. Trillion is just a word. Let’s make sure we note the significance. A *billion* seconds ago was 1994 (32 years ago). A *trillion* seconds ago was 30,000 B.C. Multiply that trillion by 40. That's 1.2 million B.C. *Over a million years' worth of debt* That’s the scale of the United States debt bill. But WAIT. It gets worse. Key point: The U.S. Treasury always has to have buyers of its debt, because if it doesn’t, the government won’t be able to pay off 1) its deficit spending and 2) the old debt coming due (and the interest on the debt). If it fails to pay those off, the Government would default and collapse. Well, then, who buys all the U.S. Government debt? Key point: The largest single buyer and owner of the U.S. Federal Government debt is THE U.S. FEDERAL GOVERNMENT ITSELF. Don’t trust, verify (picture attached below): TAKE A SECOND TO CONTEMPLATE HOW INSANE THAT IS. The U.S. Government runs a budgetary deficit, then issues treasuries to pay for the spending, then, at a bigger rate than anybody else, buys the treasuries to cover the loss.

🚨 The Bond Market Just Broke: Japan Dumps $26 Billion in Treasuries While America Is Buying Back Its Own Bonds Today, the US Treasury admitted the long end of the bond market is broken. Nobody wanted the 10-year, 20-year, or 30-year debt. The 30-year yield just slammed into its highest level since 2007 (peaking near 5.33%). So what did they do? They announced they’re AT LEAST DOUBLING their liquidity buybacks of those exact long-term bonds, from a $2 billion max per operation to $4 billion+ starting September 9. They’re literally borrowing short-term money to buy back their own long-term debt. Classic desperation move. Bond prices spiked, yields crashed 9-10 bps, and futures ripped higher the second the news dropped. Meanwhile Japan, still the #1 foreign holder of US Treasuries is dumping them to fund currency interventions. The BoJ and finance minister threatened of bold actions to save the yen. BoJ’s Yuto apologized for the measures being prepared. June data just showed Japan cut holdings by another $26.4 billion (down to $1.117 trillion). That follows the massive joint US-Japan yen-buying intervention in late July that burned tens of billions of dollars trying to stop the yen from hitting 40-year lows near 164. The yen has already given back more than half those gains and is back above 159. When the biggest foreign buyer is selling Treasuries to defend its own currency… and the US government is forced to step in and buy its own unwanted long bonds… this isn’t “market support.” This is the system flashing red. The famous City Of London banker @LordBelgrave had already warned about the planned debt, oil + currency financial crisis at the start of the year. It is now being executed. Yields are the gravity of everything, your mortgage, stocks, crypto, gold. The can just got kicked harder and farther. Don’t look away.

🇺🇸 The US Government is becoming a bigger buyer of its own debt. Treasury just announced it will at least DOUBLE long-end bond buybacks from $2bn to $4bn per operation. They call it “liquidity support.” Translation: the market is demanding higher yields to absorb America’s debt, so Treasury is stepping in as a bigger buyer of its own long-duration liabilities. This is NOT QE. Yet. Treasury can issue at the short end and use the proceeds to buy back debt at the long end. When your debt is too expensive at the long end, you move the funding shorter. And when too much debt moves shorter, refinancing risk explodes. Eventually someone has to provide the liquidity. Enter the Fed. This is the FIC (Financial Industrial Complex) at work: Treasury issues the debt. Wall Street distributes it. The banking system finances it. The Fed provides the liquidity when the system needs it. Taxpayers service it. Privatize the gains. Socialize the losses. Debase the currency when the debt becomes unpayable in real terms. You are not witnessing a $4bn story. You are watching the plumbing of a debt-based monetary system becoming increasingly dependent on intervention to keep functioning. Watch what happens next if long-end yields keep rising. That’s when Treasury “liquidity support” starts colliding with Fed monetary policy. FIC always needs more liquidity. And you are the product. A collateralised debt obligation to subside the FIC.

Yesterday I began fully integrating the @OpenAI trust cyber program into my Bitcoin Red Team efforts. This morning I woke up to see this. I am now being blocked from doing additional analysis on a codebase which I've already responsibly disclosed to, and have received confirmation had legitimate findings. To be clear, this is after having already KYC'd and completed the onboarding process months ago to use the cyber capabilities OpenAI has to offer. I am now prevented from being able to continue the investigation in a further effort to make sure their code changes are sufficient, as well as understand if there are other issues that have yet to be discovered.

I have spent over $10,000 scanning 100+ bitcoin ecosystem related libraries looking for vulnerabilities with Kimi K3 running as quarterback. Myself and a small "Red Team" have found multiple serious vulnerabilities impacting the ecosystem. They vary in scope severity, but this is a call to action. For any critical tier vulnerability that was identified if I was able to immediately demonstrate a POC (proof of concept), I have already responsibly disclosed to the maintainers. HERE IS HOW YOU CAN HELP ME IF YOU ARE NOT TECHNICAL: - please share with me any repository that is on github that I can scan, we want to cast a wide net. It takes a few moments for you to link github accounts, we'll take it from there - if that project does not have a SECURITY.md make an issue asking the dev to list one IF YOU ARE TECHNICAL: - If you are a maintainer or contributor to a project, I may have already scanned your repo, hit me up I'll share the results, if not I'll add your project to the list. - If I can trust you to do larger review to start looking through this stuff to give me more eyes let me know. AI Has forever changed software development. Tomorrow marks 1 week of Kimi k3 being live in open weights. We are going to accelerate.

I am getting a lot of questions about a Bitcoin multi-sig setup so I thought I'd create this quick guide. This is now the gold standard for serious self custody. Any single device can fail or have a flaw. Multi-sig removes the single point of failure. 1) The equipment: Mix your hardware brands. A bug in one vendor's firmware cannot touch a setup where the other two keys come from different manufacturers. -Trezor Safe 5 (wallet 1) -Blockstream Jade (wallet 2) -BitBox02 (wallet 3) -Sparrow Wallet (desktop-only) as your coordinator 2) Generate your keys: Set up all three devices completely independently. Secure the 12 or 24 word seed phrase for each. You now have three unrelated wallets. 3) Export the public keys: Open Sparrow. Plug in each device and export its XPUB. XPUBs only read balances, they cannot move funds. This step is safe. Make sure all three devices use the same script type, for example Native SegWit. Mixing address types across devices will cause errors in Sparrow. 4) Build the vault: New Wallet, Multi-Signature 2-of-3. Import all three XPUBs. Sparrow merges them into a single vault. Save and print the Wallet Configuration File. This is your blueprint and this is where people get caught out. Two seeds spend your Bitcoin. Three XPUBs find it. Bitcoin locks multi-sig funds to all three public keys simultaneously. Feed Sparrow only two XPUBs and it generates completely different addresses. Your balance shows zero. The coins are still there, you just cannot see them. XPUBs cannot move your funds, but anyone holding them can see your entire balance and transaction history. Keep a copy of the blueprint wherever a seed lives, and store it with the same care. 5) Test it: Send $5 to your new multi-sig address, then spend it back out. Sparrow will ask you to sign with any two devices. If the spend works, your setup works. Do not skip this. 6) Separate your backups: Never store them in the same place. For example... -Home: Seed 1 + blueprint -Close relative's home: Seed 2 + blueprint -Third location: Seed 3 + blueprint You can also keep an extra copy of the blueprint on its own somewhere separate. It cannot spend anything by itself. The absolute rule is that no single location should ever hold two seeds. Two seeds plus the blueprint is a spendable wallet and the blueprint is not secret enough to rely on as protection. Why 2-of-3 works: House burns down? Retrieve the other two seeds and recover everything. One device compromised by a firmware flaw? Your Bitcoin is safe. They need two. I have not covered passphrases to keep this simple. I hope this helps. Happy to assist if anyone needs any support.

This Cold Card security breach is new data that has to be taken into serious consideration as a Bitcoin holder. I am not a techy person. I am just a Dad trying to protect my family's future from the endless debasement. Do I need to become more technical in order to protect my family's sovereignty? Yes, absolutely yes. Today it was Cold Card, tomorrow it could be a different hardware wallet. I am not a coder, I have no idea which wallet has the strongest code. The question is do I have the time, energy and mental bandwidth to do this on top of all the other responsibilities I have as a father with a wife and young children. I don't know, but this weekend I need to seriously consider my options. How are you guys dealing with this?

A quick primer on #Bitcoin multisig: Multisig allows you to take custody of your BTC in a way that eliminates any single point of failure. With multisig, you will not lose your BTC if you lose a key, or if your house is broken into, catches fire, or floods. The most common type of multisig setup is a 2-of-3, meaning 2 out of 3 keys (hardware wallets) are required to sign a transaction to move/spend the BTC. With a multisig setup, you need to keep track of your keys and a descriptor file. Keys: These are typically hardware wallets that come with a paper backup for the seed phrase. With a 2-of-3 setup, you can lose one of the keys and still be safe. Best practices are to (1) store all 3 keys in separate geographic locations, (2) use a different hardware vendor for each key, and (3) back up each hardware wallet's seed phrase on steel instead of just paper. Descriptor file: This is essentially a backup of the multisig wallet configuration. The descriptor file should be saved securely and/or printed out (as a QR code). If an attacker gains access to the descriptor file, they can recreate the multisig wallet and view the BTC balance, but they can't move the funds unless they actually have access to at least 2 of the keys. If the descriptor file is lost, it can be restored, but it requires gathering all 3 keys to recreate it.
