Bitcoin (BTC) is the first decentralized digital currency in history. Just after the financial crisis in 2008, the white paper "Bitcoin: A Peer-to-Peer Electronic Cash System" was published under the pseudonym of Satoshi Nakamoto.

Nakamoto invented Bitcoin in response to the need for an electronic payment system based on the revolutionary blockchain technology, which is used to record and control transactions, instead of trust. This payment system makes it possible for two parties to perform transactions directly with each other without the intervention of a third party such as a bank.
