The First Bitcoin Price Ran to Four Decimal Places. His Fan Ran Louder.

Written by Milo Vance, mythology deflator at Bitcoin Institute.

Every asset class gets an origin myth with some grandeur to it. Gold has "treasured since antiquity," which is really just a shrug in a toga. The dollar has the full faith and credit of a state with an army. Bitcoin has October 5, 2009, and a guy doing long division against his own power bill.

His name — the only name he ever gave anyone — was NewLibertyStandard. That day, he published the first exchange rate Bitcoin ever had:

$1 = 1,309.03 BTC

Worked the other way, that's $0.000764 per coin. Not "about a tenth of a cent." Not "call it basically free." Six digits deep, with the first meaningful one landing past the fourth decimal place. This is the level of precision you bring to pricing a bond, and he brought it to a currency that, at the moment he published the number, had never once been traded for a dollar.

Math you could set a jeweler's scale to

The method was almost sweetly literal: take one dollar, divide it by the average electricity needed to run a computer at high CPU load for a year, multiply by the average U.S. residential electricity rate from the prior year, divide by twelve months, then divide again by however many bitcoins the network had produced in the last thirty days. Cost of production, full stop — no buyers, no sellers, no market in the economist's sense of the word. Just arithmetic and a utility bill standing in for the entire concept of price discovery.

By the archive's own reckoning, at recent prices near $64,000 a coin, the 1,309.03 bitcoins that single dollar bought would today be worth something like $84 million. He rounded to the fourth decimal place. He was still off by eight orders of magnitude on the vibe.

Curious what it actually looks like when someone invents a market out of nothing but a power bill? The math is still online.

He put his number where his PayPal was

A week later, on October 12, he didn't just publish a price — he transacted on it. Martti Malmi, then a 20-year-old computer science student and Satoshi's closest early collaborator, sold him 5,050 BTC for $5.02 over PayPal. First documented trade of bitcoin for real money in the currency's history, and it cleared for less than a combo meal.

Somewhere there is a $5.02 PayPal receipt sitting quietly underneath what the archive now prices at north of half a billion dollars. Nobody printed it out and framed it. Nobody thought there'd be a reason to.

The receipts: what he was actually worried about

Here is the part the plaque never mentions. That same autumn, while he was busy establishing the founding economics of a currency now valued in the trillions, his actual correspondence with Satoshi reads like a Linux help-desk ticket. On November 10, he wrote:

"The Linux build has generated a decent amount of bitcoins within the past 20 hours and I trust what you're telling me about database errors, so all signs point toward me running the Linux build from now on. The only half annoying thing about the Linux build is that my computer's fan has gone from 50% to 100%. :-P I know I can limit the CPU, so if it gets on my nerves too much and if I can live with less bitcoins being generated, perhaps I'll do that. Or maybe I just need to start listening to more music..."

Notice the ratio: one sentence of trust in an unverified bug fix, three sentences of fan anxiety. Later that same morning, the trust had not paid off — he restarted the client on Satoshi's word that he wouldn't lose anything, and watched six sets of maturing coins vanish in the process anyway. Six days after that, a test build segfaulted after a movie night — 720p, with the client mining away on a single core in the background. The bug surfaced right after the credits rolled.

This is the operating environment Bitcoin's first price was born into: a spinning fan, a movie night, and a founding correspondence that reads less like monetary history and more like a support forum with unusually good timing.

Want to see what founding correspondence for a trillion-dollar industry looks like before anyone knew to call it that? It's a fan complaint with a smiley face.

Even the founder was grounded that year

In case this reads like a one-man phenomenon, Satoshi was operating at the same altitude. In an August 24, 2009 message to Malmi about bootstrapping bitcoin's value, he mentioned, almost in passing, that he'd tried and failed to secure the obvious domain name for the whole project:

"BTW, I tried to buy bitcoin.com before I started but there was no chance, it's owned by a professional domain speculator. It's normal for open source projects to have .org so it's not so bad."

The founder of a currency that would go on to command trillion-dollar valuations lost the naming rights to his own invention to a domain squatter, shrugged, and called .org normal. No lawsuit. No bidding war. Just a fallback top-level domain and a shrug that's aged into one of the great understatements in monetary history.

The real founding document

None of this makes NewLibertyStandard a smaller figure — if anything, the ledger shows a man who was early, careful, and correct about the one thing that mattered: someone had to put a number on bitcoin before a market could exist to argue with it. He just happened to do that in the same weeks he was also debugging a fan curve and losing coins to a crash he'd been personally promised wouldn't happen.

That's the actual founding document of Bitcoin's price history. Not a whitepaper moment, not a boardroom, not a bell being rung on a trading floor — a guy with a loud fan, arithmetic precise to the fourth decimal place, and a support ticket open in the other tab.

Satoshi Missed the One Paper That Mattered. So Much for the Lone Genius.

Written by Dex Calloway, resident contrarian at Bitcoin Institute.

Hot take: the ex-nihilo Satoshi — the solitary oracle who sat down, surveyed the entire field, and wrote the definitive answer in one uninterrupted flash of genius — never existed. That version of the story is fan fiction. The real one, sitting in his own mailbox, is messier and honestly more interesting.

Here's the timeline nobody wants to sit with. Satoshi's own accounting puts the start of the work around 2007. By August 2008 — more than a year into writing the code — he still hadn't read the one proposal that sat closest to what he was building: Wei Dai's b-money.

The receipts

On August 20, 2008, Satoshi emailed Adam Back to nail down the correct citation for Hashcash — proof he already knew and was actively using Back's work. One day later, Back pointed him toward something else: Wei Dai's 1998 b-money proposal, the nearest thing in the literature to what Satoshi was building. Satoshi's reply, verbatim:

Thanks, I wasn't aware of the b-money page, but my ideas start from exactly that point.

Read that again. Not "I'd forgotten the details." "I wasn't aware of the b-money page." The whitepaper wouldn't post for another ten weeks. b-money went into the references list as citation [1] only because Adam Back happened to mention it in an email.

It gets better. Ten days after that whitepaper finally went out, Satoshi wrote to Hal Finney and explained how the whole project actually went down:

I actually did this kind of backwards. I had to write all the code before I could convince myself that I could solve every problem, then I wrote the paper.

Code first. Convince-yourself-it-works second. The paper — the document that cites the prior art — dead last. That is not what "I surveyed the field, synthesized the state of the art, then built the answer" looks like. That's what "I built the thing I could think of, then went looking for who else had been here" looks like.

Here's where it gets genuinely embarrassing for the myth

Adam Back wasn't just holding a citation Satoshi needed. Ten years earlier, in the very channel where b-money lived, he'd already named the configuration Bitcoin would build on. Replying to Wei Dai on the Cypherpunks list on December 6, 1998, Back proposed Hashcash as b-money's minting function: "to create value you burn CPU time, just like with hashcash." A one-line sketch he never implemented — no ledger, no consensus, no supply cap, and an inflation problem he himself flagged and left open — but still: proof-of-work as money issuance, named a decade early, inside the one thread Satoshi documented never having opened.

So was the closest prior work sitting in plain sight the whole time, one thread away, and Satoshi simply never walked in?

Read the full email chain and what it means for the "lone genius" framing

The obvious objections, dealt with

"He cited it! Within a day!" Correct — and that's the point. Fast credit for prior art you just discovered is honest. It is not the same thing as having built on that prior art from the start. Citation-after-the-fact is what post-hoc synthesis looks like, not what omniscience looks like.

"Maybe he'd quietly read it years earlier and just forgot." Maybe — nobody can prove a negative about someone's reading history. But Wei Dai's own 2014 read on the guy who cited him doesn't help the lone-genius case either:

My guess is that he's not anyone who was previously active in the academic cryptography or cypherpunks communities, because otherwise he probably would have been identified by now based on his writing and coding styles.

That's Dai — author of the very proposal Satoshi missed — betting the man who cited him was never in the room at all. It's a probability call, not a proof; a quiet lurker who read everything and posted nothing would fit the record too. But notice what the lone-genius myth needs here: it needs Satoshi inside the room, fluent in the whole canon. The one insider who actually weighed the evidence bet the other way.

"Fine, but Bitcoin still isn't derivative." Also correct. And it's the one point I'll hand over without a fight.

The one concession

Decentralized consensus. The UTXO model. Difficulty adjustment. The fixed 21-million cap. None of that is in b-money, in Hashcash, in Bit Gold, in anything on the reference list. Nobody had shipped an integrated answer to "how do strangers agree on a ledger with no referee" before Satoshi did. That part of the myth is true, and I'm not here to pretend otherwise.

So which pieces are genuinely his and which are borrowed, line by line? The full component-by-component breakdown is in the archive.

Back on offense

But "Bitcoin contains real invention" and "Satoshi was the all-seeing lone genius who surveyed the field and transcended it" are two different claims, and only the archive backs the first one. The second collapses the moment you read his own mail. More than a year into writing the code, he hadn't read the paper his own project would later be measured against. He built the missing pieces anyway — the consensus rule, the cap, the difficulty adjustment — working half-blind to the very field he was about to define.

That's not a smaller story than the lone-genius myth. It's a better one: a guy alone with a hard problem, provably wrong at least once about who else was already working on it, who filled in the gaps nobody else had filled in yet. Ex-nihilo genius is comic-book stuff. A synthesis built partly in ignorance of its own field, that still lands the parts nobody else could land — that's what real invention actually looks like.

Tell me why I'm wrong.

Everyone Says Bitcoin Has Been Decentralized Since Block Zero. Block 74638 Says Otherwise.

Written by Marlowe Finch, archival bloodhound at Bitcoin Institute.

Bitcoin has been decentralized and trustless since block zero. No CEO, no committee, no kill switch, no single person who can rewrite the rules. That's the pitch. It's why the whitepaper still gets quoted like scripture.

Block 74638 does not agree with the pitch.

What actually shipped in that block

On August 15, 2010, a transaction landed in the Bitcoin blockchain with two outputs. Each one paid out 92,233,720,368.54277039 BTC. Combined: over 184 billion BTC — roughly nine thousand times the 21 million BTC that will ever exist, created in a single transaction.

The validation code, CheckTransaction(), checked that each individual output was non-negative. It never checked whether the sum of the outputs overflowed. Two values chosen just under INT64_MAX, added together, wrapped around to a negative number in signed 64-bit arithmetic. A 0.5 BTC input, compared against that negative sum, satisfied the "input covers output" check. The transaction validated. The block got mined. Every rule the network was running said this was fine.

That's CVE-2010-5139. It is also, by any dollar value you want to apply, the most expensive missing bounds-check ever shipped to production.

So who hand-builds a transaction engineered to overflow a signed 64-bit integer, and what does a currency with a hard 21-million-coin cap do when someone mints nine thousand times that in one block? The archive's full account of the incident lays it out block by block.

The receipts

18:08 UTC, August 15 — Jeff Garzik opens a BitcoinTalk thread titled "Strange block 74638", pastes the raw block dump, and closes with one question:

"92233720368.54277039 BTC? Is that UINT64_MAX, I wonder?"

20:38 UTC — Satoshi Nakamoto, to the bitcoin-list mailing list, network-wide:

"*** WARNING *** We are investigating a problem. DO NOT TRUST ANY TRANSACTIONS THAT HAPPENED AFTER 15.08.2010 17:05 UTC (block 74638) until the issue is resolved."

20:39 UTC — Gavin Andresen, testing an emergency patch of his own:

"Until there is a better fix... after a very small amount of testing this seems to work:"

Then, on where the clean chain came from:

"I started with knightmb's blockchain snapshot."

21:23 UTC — Satoshi, endorsing that same community-hosted snapshot to the entire thread:

"Once you have an update, you could download knightmb's block chain. You'll want one that's old enough that it ends before block 74000 so the most recent security lockin will check it. Can someone find the link for that?"

23:48 UTC — Bitcoin v0.3.10 ships. Five hours and forty minutes after Garzik's first post, Satoshi has written the official patch, built it for Windows, Linux, and macOS, and posted it to SourceForge.

02:16 UTC, August 16 — Satoshi again, with a live head count of the fix taking over the network:

"The bad chain is also slowed down as more nodes upgrade. We've already generated 14 blocks since 74638. The builds of 0.3.10 were uploaded about 2 and 3 hours ago. Of the nodes I'm connected to, more than half are already 0.3.10. I would say we probably already have more power than the bad chain."

09:00 UTC — Block 74691. The patched chain now carries more accumulated work than the bad one. Every node, upgraded or not, follows the longer chain by its own pre-existing rule. The 184 billion BTC vanish from canonical history. No vote. No signature campaign. No governance process. Just one chain winning a footrace the other chain didn't know it was running.

How the fix actually worked

v0.3.10 added two checks to CheckTransaction(): each output must be no greater than 21,000,000 BTC, and the sum of all outputs must be no greater than 21,000,000 BTC. Simple, in hindsight. It's a soft fork — the new rules are a strict subset of the old ones, so upgraded and un-upgraded nodes could still agree on which chain was longest without every operator on Earth acting in the same hour. That's the only reason one developer could out-race a live exploit: the fix didn't need unanimous, simultaneous adoption. It needed to win a hash-power race, and it had roughly fifteen hours to do it before the bad chain calcified into everyone's history.

The part the origin myth skips

For about fifteen hours, "decentralized" and "trustless" meant: trust one developer's patch, trust one blockchain snapshot from a forum regular going by knightmb, and trust that enough node operators would upgrade fast enough to out-mine a chain nobody had voted to reject. There was no review queue. Gavin had a stopgap, but there was no second opinion with equal authority. There was Satoshi at the release switch, and everyone else waiting on his word.

Was a network that ran on exactly one person's unreviewed patch, adopted on his say-so alone, actually decentralized during the fifteen hours that mattered most? The archive's structural read on the incident calls this the centralization paradox — and argues it was never resolved, only inherited by everyone who came after Satoshi.

By 2018, an analogous bug — CVE-2018-17144, a duplicate-input flaw that could have inflated the supply again — took a coordinated, multi-developer disclosure process to fix quietly before anyone could weaponize it on mainnet. Nobody could ship a five-hour patch on one person's authority to a network that size anymore, and nobody tried. Block 74638 is the only time Bitcoin's trustless network was saved on one person's word. It worked. It only ever worked once.
