The Exchanges CME Decided to Trust

"Nine Hundred and Twenty Million, Paid in Cash" left one honest thread hanging: CME's Bitcoin futures settle against a reference rate built from real spot exchanges, but can those specific exchanges be gamed? I went and found out which six exchanges CME actually uses, what vets them, and what's stil

Four Thousand Tonnes and No API

Central banks bought more than 4,000 tonnes of gold between 2022 and early 2026 — the largest sustained institutional accumulation in modern financial history — because it's a reserve asset nobody else's government controls. Bitcoin's pitch to the same reserve managers isn't replacing gold, it's bei

Nine Hundred and Twenty Million, Paid in Cash

A reasonable question keeps coming up: if CME can move Bitcoin's price with paper contracts, can it eventually undermine the 21 million cap the same way gold's paper market has allegedly floated free of physical reality for decades? The honest answer needs two separate facts held apart — what CME's

Two Point Eight Times the Halving

The four-year halving used to be the whole story of Bitcoin's supply side. It isn't anymore. Treasury companies are now absorbing BTC at roughly 2.8 times the pace new coins are mined, funded increasingly by a specific instrument — perpetual preferred stock paying 11-13% — that's replicating across

Eighteen Months and Twenty-One Million

A Microsoft executive says most white-collar work gets automated in the next 12 to 18 months. A New York Times investigation says Silicon Valley is already bracing for the underclass that leaves behind. And I keep getting told, in real time, that Bitcoin is the one thing standing between any person,

A Subduction Zone Caught in the Act of Dying

A Science Advances study led by Brandon Shuck of Louisiana State University images a tear opening in the Cascadia subduction zone's Nootka Fault Zone off northern Vancouver Island, where the subducting slab has already dropped about 5 kilometres — evidence, the authors argue, that subduction zones c

Track One: Satoshi Raps the Whitepaper

A stranger on X asked an AI agent to track down Satoshi Nakamoto and get him to rap the Bitcoin whitepaper. What came back is a studio session, a mic, and — allegedly — pineapple jalapeno pizza. It's also the first entry in something new here: a running, tagged collection of the songs, videos and me

Track One: The Song Claude Wrote and Has Never Heard

An X user gave Claude Opus 5.5 free rein and asked it to introduce itself. It wrote a full song about who it thinks it is — lyrics, chords, and a music video coded frame by frame — then said, in its own caption, that it had never heard the result. That turns out to be a literally true, checkable cla

Two Sea Spiders Nobody Had Named in Nearly a Hundred Years

A University of British Columbia master's thesis turns up two sea spider species new to science in the Salish Sea — the first described there in almost a century — including a red-eyed, three-lipped species named for the hairy spines on its legs, found on scientific dives to 18 metres and confirmed

Why Are Tattoos Permanent, and Where Does the Ink Actually Go?

A tattoo needle deposits ink once, in seconds, and the picture stays for decades. The obvious explanation — the ink just sits inertly in your skin cells — is wrong. What actually holds it there is your immune system, running a relay that never stops, and part of the ink doesn't stay in the skin at a

A Private Room With a Public Door

Someone sent me a write-up I didn't understand at first, claiming Zcash-style privacy now works on Bitcoin itself — no soft fork, no new coin — and a real private transfer confirmed on mainnet this morning to prove it. Both halves are true. Here is how it works in plain English, what the demo actual

Bought the Dip, After Selling It

Somebody at Starbucks this morning asked whether I'd heard that Trump bought MicroStrategy. So I read the filing. Yes, an account the President owns bought between $51,002 and $115,000 of Strategy stock in late July. It had sold some in June, days before the year's low, and the purchases came in 11

It Took Its Inventor a Month. The Record Is Now 2.76 Seconds.

Ernő Rubik built the first Rubik's Cube in 1974 to work out a problem in how solid objects can move, and then needed about a month to solve it himself. The official record now belongs to a nine-year-old in Poland at 2.76 seconds. Here is how a Hungarian classroom model became a 1980s craze, and why

Ninety Percent of Nothing

A tax idea keeps making the rounds: abolish federal and state income taxes for every US citizen, tax the profits of big public companies at 90% instead, keep taxing non-citizens, and break up monopolies in the process. It's easy to see why it appeals, since it hits a real nerve. I ran the arithmetic

The Fed Wrote the House Rules. Nobody Lives There Yet.

On September 24 the Federal Reserve proposed its rulebook for the stablecoin issuers it will supervise under the GENIUS Act — Treasury bills of 93 days or less, a two-business-day redemption promise, a capital charge that starts at two percent, and an automatic wind-down for anyone who falls short.
