A man deposits $10,000 in a bank.
The bank thanks him and records the deposit on its balance sheet. But not where you might expect. For the bank, that $10,000 is actually a liability – because technically it belongs to the customer and might have to be returned.
So the bank does what banks do. It lends $9,000 of that money to someone buying a car.
Now something interesting happens. The $9,000 loan appears on the bank’s books as an asset – because someone now owes the bank money.
So the same $10,000 is doing two jobs at once. The depositor believes he has $10,000 safely in the bank. The borrower now has $9,000 to spend.
That $9,000 gets deposited somewhere else. The next bank lends $8,100. That gets deposited again. Then $7,290 gets lent out.
Soon the original $10,000 has quietly turned into tens of thousands of dollars of loans scattered across the economy.
Everyone believes they have money. Depositors see balances in their accounts. Borrowers have the money they spent. Banks show healthy assets on their balance sheets because people owe them money.
And here’s the best part.
Banks charge interest on all those loans – maybe 7%. But the depositor who supplied the original money might earn only 0.5% on their savings account.
So banks collect interest on money that mostly wasn’t theirs to begin with – and keep the difference.
The system works beautifully.
As long as nobody asks for the money back at the same time.
“You can’t create more than 21 million Bitcoin onchain.”
But offchain?
Jim Bianco ( @biancoresearch ) warns we've built “a fractional reserve system around Bitcoin.”
“The ETFs, TradFi borrowing… to buy Bitcoin, structured products… tied to the ETFs, treasury companies..."
We’re creating “many billions of dollars of crypto buying that is not onchain.”
“When the market started to crack… it was the synthetic markets that cracked.” 📉
Catalysis 2025 Roundup: The year onchain risk coverage became inevitable.
This year institutions moved onchain at full velocity.
Restaking matured into financial guarantees. RWA credit expanded, stablecoin rails grew massively.
Bottleneck? Risk scaled faster than protection.
Private equity is coming onchain 💰

1. Many scholars believe that Tolkien's 1911 hike through Lauterbrunnen directly inspired the valley of Rivendell in The Lord of the Rings.

*They are not a small engineer team but one of the leading frontier lab (+100 researchers full time).
*They are not a newcomer. Started in 2023 by retraining a llama, then slowly rising to the top. All documented in their 16 (!) papers.

Really happy to see this project become a reality and such a success. The documentary film Longevity Hackers, narrated by @_EdwardNorton_ , is finally released after almost four years of work. The film explores the latest research in the field of longevity and features scientists like me as well as mainstream celebrities and experts like @TonyRobbins , @markcuban , @steveaoki , @tonyhawk , @PeterDiamandis , @chrismirabile and many more.
Director @misiewierski and producer @RubenFigueres did an amazing job at bringing this issue, possibly the most important of our lifetime, to the front of the spotlight.
The film is available at Apple TV (https://t.co/UcH2E4ug0x) and Amazon (https://t.co/vbbfQfzxic). Please spread the word so that more organisations and governments make the fight against aging a priority.
GROK IS YOUR AI DOCTOR
Imagine a world where your smartphone isn't just for doom-scrolling through social media or capturing questionable selfies but where it can also play doctor.
Grok can now give you the lowdown like it's been to medical school.
Elon:
"You can upload anything from a phone picture of your blood test results to an MRI or X-Ray and Grok will analyze it for you."
Grok's analysis won't just tell you, "Yep, that's an MRI," or "Those numbers look... numbery."
It'll dive deep, offering insights from spotting peculiarities in your blood work to interpreting those shadowy blobs on your X-rays.
Now, while Grok isn't a real doctor, it's pretty adept at providing initial interpretations.
It could point out if your cholesterol levels are on a joyride or if there's something unusual lurking in your MRI that might warrant a follow-up with an actual medical professional.
