> “Bitcoin is not having a crisis. It’s having an election,” says Brian Armstrong, the CEO of Coinbase, a very well funded startup based in San Francisco. “The [prevailing] mental model for what’s going on is a split, a divide in the community. But the right model is an election.” ... Bitcoin is designed to operate as a democracy, and indeed, it’s deep into a major election. This is pretty much how things are supposed to work.
Is it? That's really what this is all about.
Unlike a constitutional political system, Bitcoin has no explicit meta-rules that govern how to change its basic rules. On one side of the present "civil war" over the size of transaction blocks is a group that wants to make a minor technical change to the protocol to allow it to support a higher volume of transactions; and on the other side is a group that doesn't want that to happen.
But these groups really represent two sides of a more substantial debate. One side is advocating for the first deliberate change to the protocol's basic rules, and the other side is saying, no, you can't do that. Michael Marquardt (aka theymos), who controls bitcoin.org, bitcointalk.org, and /r/Bitcoin, and who is a vehement proponent of the status quo, has made plain his position in this meta-debate: "Bitcoin is not a democracy."
And that's the position taken by several Core developers, who insist that the block-size is a "technical issue" over which users and stakeholders should have no say. Gregory Maxwell, a vocal Core developer on the status-quo side of the debate, and many others, object to changing the protocol in ways that could cause a fork in the blockchain, with clients following one set of rules going one way and clients following other rules going another. It's an objection in principle as much as a practical concern: nobody should be coerced into submitting to a new set of rules by the risk of being separated from the mainstream of the Bitcoin community, and that means we have to stick with the present rules. (Its exponents call this philosophy "consensus".)
So it's the newest setting for the oldest and most basic conundrum of politics: bad rules are bad, but so is changing the rules of the game halfway through. Artificially constrained blocks are driving up the cost of transacting in bitcoin and hampering the currency's adoption; but rules are rules, say people like Maxwell and his colleagues at Blockstream, who have carefully arranged their lives and built their businesses on the assumption that the present rules will be the future rules. (Blockstream is a company that employs several Core developers and is building a mechanism for transacting in bitcoin off the blockchain, i.e., a mechanism for providing more transaction capacity to an artificially limited protocol.)
And Maxwell and his colleagues have a point. We are, after all, talking about the rules of a currency that was created in part to take away from central bankers, politicians, and the masses the ability to change the rules of the game halfway through. If the block-size limit can be changed, what's to prevent people from changing more important rules, like the one that keeps bitcoin's money supply from growing without bound?
Still, as the saying goes, rules are made to be broken—and the peasants do tend to revolt.
Edit: I edited my comment to properly attribute to Marquardt words that I mistakenly recalled coming from Maxwell. I also tried to clarify a couple of points.
- Hermel 11y agoThis particular rule you are referring to was introduced as a temporary fix. Satoshi himself described how to change it later on. Thus, it is in fact Maxwell and his companions who are changing the rules of the system by refusing to execute what the inventor initially planned.

- bachback 11y agoWell, Maxwell is wrong in the sense that it is the fault of the system of favouring expert rule against user will. Due to mining centralisation users have lost their power, although really never exercised it in full. They only exercise it in the sense that they can stop inflation, but not much else. The far more interesting question is what better consensus systems will be capable of. In the first article on blockchains the system was described as a "constitutional microdemocracy". http://szabo.best.vwh.net/securetitle.html http://szabo.best.vwh.net/securetitle.html If one follows Core's line the question becomes: who if not nodes make decision in Bitcoin? Their answer - the core developers. A future system will have to address this corruption of power.
- maaku 11y agoThat completely mis-characterizes Maxwell and Blockstream's position. It isn't that "the rules are the rules and we got to live with them." Rather larger, slower to validate, slower to relay blocks creates centralization pressures, and centralization destroys the user protections at the heart of Bitcoin's value proposition. Blockstream has no position on the block size debate, other than supporting the consensus building process (whatever the outcome might be). Blockstream's business model does not depend in any way shape or form on small blocks. That is pure FUD. In fact, small blocks are a hindrance to things like sidechains, which generally use much larger transactions for the two-way peg smart contracts. Some of the risks called out in the sidechains whitepaper are that Bitcoin blocks might be too small to contain a return peg, or that full blocks will make it difficult to get a fraud proof on chain before the expiry. Everyone stands to benefit from larger blocks, but only so long as the network remains decentralized. The debate is over where to draw that line. (Disclaimer: I'm a co-founder of Blockstream.)
