The war of the blocks
Signal21 Editorial Desk
A question with a precedent
Our consortium coverage this week raised an objection we took seriously: whoever pays the developers ends up, indirectly, choosing what Bitcoin becomes. The strongest answer is not a theory but a precedent. In 2017, during what is remembered as the war of the blocks, the best-capitalized coalition in Bitcoin's history tried to change the protocol's rules with nearly every visible lever of power on its side. Replaying that episode in detail is the fairest way to weigh what money can and cannot do here.
Two paths out of the same dispute
For years one part of the ecosystem had wanted to raise Bitcoin's capacity by enlarging the blocks themselves. No consensus formed around that change, and the disagreement finally split into two distinct strategies. One camp stopped waiting: on 1 August 2017 it activated a hard fork with bigger blocks, and the result was Bitcoin on one side and Bitcoin Cash on the other — a separate network with its own rules. The other strategy, SegWit2x, aimed for something more ambitious than a breakaway: a negotiated compromise that the whole network would accept as an upgrade of Bitcoin itself, not a departure from it.
The most backed proposal in Bitcoin's history
That compromise had been struck in May 2017, when a coalition of large companies and miners met in New York during an industry conference and signed what became known as the New York Agreement. Coinbase, BitPay, Bitmain, Blockchain and Xapo were among the backers, and the agreement claimed the support of 58 companies across 22 countries and of miners representing over 80% of global hashrate. The plan came in two steps: first activate SegWit, an upgrade optimizing how block space is used, which the other camp had long demanded; then, months later, double the base block size through a hard fork. On paper, nearly everything that looked capable of steering Bitcoin stood behind it — and the first step did happen, with SegWit activating in August 2017.
The suspension
The second step never came. As the hard fork approached, it became clear that a large share of developers, users and node operators would not follow. Pressing on would not have changed Bitcoin in any uncontested way; it would most likely have created yet another parallel chain. On 8 November 2017, days before activation, the project's leaders suspended SegWit2x, writing that they had not built sufficient consensus for a clean upgrade. The claimed 58 companies and the majority of hashrate had not been enough — a result that only makes sense once you look at what a node actually does, which is where we pick up next.
What Signal21 takes from it
The 2017 episode is the cleanest natural experiment Bitcoin has produced on the question our consortium series keeps circling: institutional weight, however visible, has never been the unit in which Bitcoin's rules are decided. None of this history changes the near-term tape, where our short- and medium-term view stays Bearish Bias on unrepaired price structure. It does inform the long horizon, where our view remains Strong Bullish: an asset that has already survived its best-funded takeover attempt carries evidence most assets never get to accumulate. This is market analysis, not a recommendation to buy or sell any security.
