a record, not a rant
That's the first sentence of Satoshi Nakamoto's 2008 whitepaper. This page documents, with dates and sources, how a small number of people came to decide that block space had to stay artificially small — and what happened to Bitcoin's use as everyday cash once they got their way.
Satoshi Nakamoto wrote, in the whitepaper's own first line, that Bitcoin was a system for peer-to-peer electronic cash. Not digital gold. Not a settlement layer for institutions. Cash — something anyone could send directly to anyone else, with no bank, no border and no permission required.
What the record actually shows, not as prediction but as history: a single mining pool held a majority of the network's hashpower in 2014, under the same small-block policy that was supposed to prevent exactly that. The blockchain itself has grown to roughly 870GB, pricing ordinary people out of running their own full node anyway. For years, while blocks weren't full, typical fees sat around a penny — proof small payments worked fine on-chain, until the fixed 1MB cap failed to grow alongside demand and congestion took over. Steam accepted Bitcoin in 2016 at 20 cents a transaction and dropped it in 2017 when the same fee hit $20, saying so publicly, in their own words. None of that is speculation — it happened, on schedule, while the block-size increase that was promised in writing never arrived.
On top of the technical bottleneck sits a policy one: in most jurisdictions, Bitcoin is classified as property, not currency. Spending it on a coffee is treated as disposing of an asset — a taxable event a pound in your pocket never triggers. And getting hold of it in the first place, for almost everyone, means passing through a handful of government-licensed, identity-verified exchanges — the exact kind of centralized, monitored gatekeeper Bitcoin was built to route around.
None of this was inevitable. A version of Bitcoin that scaled its base layer instead of freezing it could have let a million people each send a fraction of a cent to someone in poverty and have it arrive, directly, in minutes — no bank, no remittance fee eating half of it, no government able to block it. That is what “peer-to-peer electronic cash” was for. It is not what Bitcoin does today.
Somebody wrote down, plainly, what this was for. He isn't here to defend that statement anymore — and a small group of people who came after him decided that gave them room to redefine it. Stating what a thing's inventor said it was for, in his own words, isn't a fringe position. Treating his stated purpose as negotiable the moment he's no longer around to object to the rewrite is the actual departure from the record.
Small blocks did not deliver the decentralization and accessibility they were sold on. That's the claim this whole page is built to show — plainly, and with dates.
Hong Kong, 21 February 2016 — the Bitcoin Roundtable Consensus
After an 18-hour closed-door meeting at Hong Kong's Cyberport, mining companies representing roughly 80% of network hashpower and a group of Bitcoin Core developers — including Adam Back, signing on behalf of Blockstream — published a joint public statement.
Segregated Witness would ship within ~2 months. In exchange, Core developers committed to producing code for a hard fork raising the block size, to be recommended within 3 months of SegWit's release, targeting activation around July 2017.
SegWit shipped roughly on schedule. The block-size hard fork code did not arrive. Blockstream's Gregory Maxwell publicly rejected the agreement after it was signed. Bitmain's Jihan Wu later accused developers of having “unilaterally torn up” it.

four moments, in order
Version 0.9.0 shipped a new default: any non-payment data attached to a transaction was limited to 40 bytes, framed as an anti-spam measure. Services already using OP_RETURN for document timestamping and early asset protocols were broken outright.
Raised to 80 bytes in Core 0.11 (2015) after public pushback. The underlying question — who decides what's a legitimate use of the chain — resurfaced again in 2025.
Moderators of the largest Bitcoin discussion forum at the time carried out a mass wave of bans and removals targeting any mention of Bitcoin XT, a rival client proposing larger blocks. A user was banned for posting two comics. Another was banned for counting how many people had just been banned.
“...regrettably escalated to censorship.”
— a moderator's own public statement, preserved and widely quoted since.
See above. Adam Back signs for Blockstream. SegWit ships. The block-size increase does not.
A second, broader version of the same deal — backed by companies representing ~83% of hashpower — was called off with no explanation required and no consequence attached to any signatory. Blockstream's Samson Mow had publicly opposed it beforehand, stating a hard fork “is not needed now.”
the base layer today, sixteen years after the whitepaper
A system that can't clear a coffee purchase without a second-layer workaround, or without paying more in fees than the coffee cost, is not functioning as the whitepaper's first sentence describes. That's not an opinion about the future — it's what already happened, on the record, while the promised capacity increase never arrived.

the funding behind the small-block position
The small-block argument wasn't anonymous. It was made, on the record, by named Bitcoin Core contributors — several of whom were, at the time, on the payroll of a company whose products depend on Bitcoin's base layer staying capacity-constrained.
“Before discussing increasing block size, there must be evidence that transaction load has gone over the optimum level for creating a market for fees.”
— note the date: this is before Blockstream existed. The fee-market argument predates the company that would later profit from it.
“Increasing the size of blocks now will simply make it cheap enough to continue business as usual for a while.”
— Bitcoin dev mailing list
“Fee pressure is an intentional part of the system design and essential for the system's long term survival.”
— #bitcoin-wizards IRC
“[Bitcoin's blocks are] already too big.”
— Decrypt interview. Drew public criticism at the time — compare with his own video above, from a year earlier, titled “Why Small Blocks are Important for Bitcoin.”
Blockstream, founded 2014, has raised well over $200M across its life — including a further $210M in October 2024 — and its revenue sits mostly off Bitcoin's base layer: the Liquid sidechain, Blockstream Mining, and since 2025 a Bitcoin asset-management arm. It employed Maxwell (until 2021), Wuille, and Mow, among others quoted above.
“Some Bitcoin quarters contend that where Bitcoin comes short, that's where Blockstream profits.” Critics say the company kept the block size small to suit its own sidechain business, and hired community developers to work on Blockstream products rather than base-layer scaling.
CryptoVantage, May 2021; Decrypt, Oct 2020; Blockstream press release, Oct 2024.
Fair to say plainly: the fee-market argument didn't start with Blockstream's money — Maxwell was making it in 2013, before the company existed. What Blockstream's funding changed is who had the strongest incentive to keep making it, once SegWit and Liquid turned a capacity-constrained base layer into a business model rather than just a technical position.
what the people arguing for peer-to-peer cash said, at the time
“It is urgent. Looking at the transaction volume on the Bitcoin network, we need to address it within the next four or five months.”
He went further: “My fear is there'll be no critical event that causes people to react — Bitcoin just kind of has a long slow death.”
— MIT Technology Review
“The block chain is full… an entirely artificial capacity cap of one megabyte per block… has not been removed.”
“[Bitcoin] has become something even worse: a system completely controlled by just a handful of people.”
— “The resolution of the Bitcoin experiment”
“Even if you like the changes that Bitcoin Core has made, the historical record is clear that they radically differ from the original design.”

his own forum posts, dated and sourced — not paraphrase
The 1MB limit itself was Satoshi's: he added it in July 2010, as an anti-spam circuit breaker while the network was still tiny. What he said about it, on the record, in his own words, was that it was a dial to be turned — not a permanent ceiling.
“The threshold can easily be changed in the future. We can decide to increase it when the time comes. It's a good idea to keep it lower as a circuit breaker and increase it as needed.”
— BitcoinTalk, “Always pay transaction fee?” thread
“It can be phased in, like: if (blocknumber > 115000) maxblocksize = largerlimit. It can start being in versions way ahead, so by the time it reaches that block number and goes into effect, the older versions that don't have it are already obsolete.”
— BitcoinTalk, reply to “[PATCH] increase block size limit”
Worth noting the complication rather than hiding it: Satoshi also wrote, in July 2010, that he anticipated “there will never be more than 100K nodes, probably less,” with most participants running lightweight clients instead of full nodes — the same node-count tradeoff Adam Back invokes above to justify keeping blocks small. Satoshi didn't resolve that tension himself. What he did say plainly, twice, on the specific question of the block size threshold itself, is that it was designed to be raised — a circuit breaker, not a target.

why “just fork it” hasn't worked, and what actually would
A block-size increase can only happen as a hard fork — a node running the old rules sees an oversized block and rejects it outright, full stop. That's structurally different from Segregated Witness or Taproot, which were soft forks: the rules only tightened, so an un-upgraded node could still accept the new blocks without understanding them. That difference is why Segwit could be forced through by a fraction of the network — BIP148, August 2017, nodes simply started rejecting non-Segwit blocks and made it too costly for miners not to comply — without needing every business, wallet and exchange to move in lockstep first. A block-size hard fork has no equivalent shortcut. Everyone moves together, or the network splits, and whichever side has less of the economic majority gets treated as the new coin.
Gavin Andresen's BIP 101 wasn't a breakaway attempt — it specified a hard fork that would only activate once 750 of the last 1,000 blocks (75% of hashpower) signaled support, with a two-week grace period after. The design was explicit: hit that threshold and the old chain becomes the minority, not the other way around. It stalled well short of it.
This one got close — something like 80–90% of mining pools and major businesses had signaled support. It still collapsed days before activation, because miners don't enforce the rules alone; full nodes do, and enough of the node-operating, wallet-running side of the network refused to go along that proceeding risked exactly the fracture everyone was trying to avoid.
After roughly $50M was stolen from a project called The DAO, the Ethereum Foundation pushed a hard fork to reverse the theft. It kept the name. Same ticker, ETH, same everything. The untouched original chain became the footnote, renamed Ethereum Classic. A vote beforehand showed 87% support among participating ether, and the Foundation's trademark plus its developer and exchange backing meant the market simply followed.
Bitcoin was deliberately built without an equivalent to the Ethereum Foundation — no company, no trademark owner, nobody who can declare which chain is “real.” That's normally called a feature. In practice, the small group everyone's wallets and exchanges defer to by default sits in the same seat the Foundation did — they've just only ever used it to block a change, never to declare one.

node count is one measure. it isn't the only one.
The standard small-block argument — Adam Back's own framing, in section 05 — is that bigger blocks mean fewer people can afford to run a full validating node, so bigger blocks mean less decentralization. That's a real metric. It is not the only one, and it's conveniently the one that happens to justify capping the layer Blockstream's own products profit from constraining.
There's a second, equally legitimate measure: how many people actually hold and move their own bitcoin directly, peer to peer, with no custodian, exchange or Lightning hub standing in between. That's the decentralization the whitepaper's first sentence was actually describing. Small blocks didn't protect it — they shrank it. Fees that spiked past $20 during congestion (section 04) didn't make more people run nodes; they pushed ordinary payments off-chain entirely, into exchanges and custodial wallets — the exact intermediaries Bitcoin was built to remove. A base layer that scaled with demand instead would likely mean a smaller share of users bother running a full node — Satoshi himself expected that trade-off, back in section 08 — but a far larger number of people actually transacting in bitcoin directly, without asking anyone's permission first. That's a more decentralized outcome in the sense that was supposed to matter. It just doesn't show up on the one graph small-blockers chose to measure.
Most people holding bitcoin today were never handed that trade-off in full. They got a one-line slogan — bigger blocks, worse decentralization — presented as settled fact, from the same small group whose position benefits from it being accepted without question. Given the fuller picture, it's a reasonable bet most of them would prefer the version of Bitcoin that lets them actually spend their own money peer-to-peer, not just the version that lets more hobbyists run a node nobody downstream of them is using.
small blocks forced a choice between cash and asset. the choice had a beneficiary.
Two unrelated decisions landed the same year and pushed the same direction. In 2014, Bitcoin Core capped OP_RETURN and the small-block position began hardening (section 03). In March 2014, separately, the IRS ruled Bitcoin was property, not currency, for tax purposes — while it was still trading in the hundreds of dollars, still niche, still very much being used as everyday cash by the people who held it. Nobody needed to coordinate those two events for them to compound: one made Bitcoin technically harder to spend at scale, the other made spending it a taxable disposal of an asset rather than moving money. Between them, “store of value” became the only lane left standing.
“It's a fraud... worse than tulip bulbs.”
— Jamie Dimon, JPMorgan CEO, 2017
“Rat poison squared.”
— Warren Buffett, 2018
Before the US approved spot Bitcoin ETFs in January 2024, regulated institutional ownership of Bitcoin was effectively zero. By mid-2026, ETFs and corporate treasuries together held over 9% of all the Bitcoin that will ever exist — roughly 1.28 million BTC in US spot ETFs alone, plus 750,000+ BTC in corporate treasuries, Strategy (formerly MicroStrategy) the largest single holder at around 580,000 BTC.
Jamie Dimon reversed course. JPMorgan began offering clients access to Bitcoin. Same man, same institution, eight years between calling it a fraud and helping clients buy it.
None of this requires a conspiracy to explain. Nobody needs to have colluded for a tax ruling and a code decision made in the same year, for unrelated reasons, to compound into the same outcome — or for institutions that spend a fortune on failing to guess right early to simply buy in once the guessing was over. What's fair to say plainly: the class with the least reason to want peer-to-peer cash to succeed dismissed it for most of a decade, then arrived, in volume, the moment it had safely become something else.

Worth saying directly, for anyone reading this as more than it is: this isn't a claim that banks and governments planned any of it together. It's simpler and harder to dismiss than that — two separate sets of people, with two separate motives, both happened to benefit from Bitcoin failing at the one job it was built for, and neither had to lift a finger to make it happen.
not speculation — the size of the gap, in numbers that already exist
1.3 billion adults worldwide still have no bank account (World Bank Global Findex, 2025). Migrant workers sent roughly $650 billion home to their families last year, at an average cost of 6.36% of the amount sent — call it somewhere north of $40 billion that never arrived, taken in fees, by people who by definition don't have much to spare. The World Bank's own estimate is that cutting those fees by just five percentage points would save $16 billion a year. That's not Bitcoin's marketing material. That's the World Bank describing the problem peer-to-peer electronic cash was designed to solve, without mentioning Bitcoin at all.
None of this is a promise that Bitcoin, running at that volume, would have closed the gap cleanly — a payment system carrying that scale brings real problems of its own, and nobody gets to run the experiment now to find out. What can be said without overreaching is narrower, and still large enough to sit with: the tool built to move value directly, for a fraction of a cent, with no bank and no border in the way, had its capacity capped at close to the exact moment it might have started doing that job at scale. Ten years on, the fees, the delays and the 1.3 billion people still outside the banking system are all still fully intact — on a scale measured precisely, by people who aren't Bitcoiners and have no reason to exaggerate it.
“A purely peer-to-peer version of electronic cash.” That's still the first sentence. This page is the record of how far short of it the base layer was allowed to stay, and who that suited.
