What is Bitcoin

What is Bitcoin, and why do people around the world talk about it? Normally, electronic payments go through banks, which check and control every transaction. In two thousand eight, an inventor using the name Satoshi Nakamoto proposed a way to skip the middlemen. He described the idea in a short document known as the Bitcoin whitepaper.

How the network works

In two thousand nine, the Bitcoin network went live: a network of equal computers run by ordinary users. About every ten minutes, these computers record checked transactions into a new block. The blocks link together one after another, forming a public chain called the blockchain. To change an old record, someone would have to rewrite the whole chain, so the data is very well protected.

The key rules

The number of coins is strictly limited: there will never be more than twenty one million bitcoin. Every two hundred ten thousand blocks, the halving happens, and the reward for new blocks is cut in half. Satoshi Nakamoto built these clear rules into the system from the very start. The main idea: Bitcoin gives people the freedom to send and hold money directly, without middlemen.
