Money without a middleman
A file can be copied. So can digital money, and that means spending it twice. Until now a central party prevented this: the bank keeps an account and deducts the amount. Anyone who wants to do without such a party needs another way.
The core problem is called double spending.
Bitcoin solves it by having a worldwide network of computers keep the same ledger. Every payment is passed to everyone, everyone checks it, and whatever is written in it reads the same for all. Spending one coin twice is noticed immediately.
Payments are bundled into blocks. Each block contains the fingerprint of its predecessor, a checksum derived from that block's entire contents. If someone changes an old block, its fingerprint changes, and every block after it no longer fits.
Each block hangs on the one before. Hence chain.
There will never be more than 21 million bitcoin. That limit is part of the rules all participants have agreed on. Nobody can print more, no government either, and not in a crisis. Unlike state money, the supply is not subject to a decision.
A number in a paper is not a promise. With Bitcoin the cap is credible because it does not hang on a decision but on software running on tens of thousands of other people's computers. Anyone wanting to change it would have to get practically all of them to run a different version at the same time.
And they would have nobody on their side: whoever holds bitcoin loses from a higher cap, and whoever mines is paid in the same currency. The rule holds because breaking it hurts everyone who would have to enforce the break.
That is the real difference from state money. There the supply is the subject of a trade-off between goals that can conflict. That is not an accusation; it is a different design. Bitcoin trades adaptability for predictability.
Coinovo also has a fixed cap: one billion CNVO. Only here it is NOT credible in the same sense, and that deserves saying. It sits in software that lives in one place and can be changed by one operator.
That difference is worth understanding: a cap is only as sound as the answer to who could change it. For Bitcoin: nobody alone. For almost every other project including this one: the operator.
Knowing that, you read every paper differently. The number is never the answer; the answer is what the number hangs on.
One bitcoin can be split into 100 million units. The smallest is called a satoshi, after the pseudonym of its creator. So you do not have to buy a whole bitcoin, any more than you have to buy a whole kilo bar of gold.
It is not a company, it has no board and no head office. There is nobody who could reverse a payment, freeze a balance or change the rules alone. That is the advantage and at the same time the risk: mistakes are final.
