The creator of Bitcoin, Satoshi Nakamoto,
Bitcoin is an experimental property transfer and verification system based on a peer-to-peer network without any central authority.
The initial application and the main innovation of the Bitcoin network is a decentralized electronic money system whose bitcoin is the unit of account.
Bitcoin works with software and protocol that allows users to issue bitcoins and manage transactions collectively and automatically. As a free protocol (open source code), it also allows interoperability of software and services that use it. As a currency bitcoin is both a payment intermediary and a store of value.
Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed evenly by computing power across the network, and will be limited to 21 million units divisible up to the eighth decimal place. The smooth functioning of the exchanges is guaranteed by a general organization that everyone can examine, because everything is public: the basic protocols, the cryptographic algorithms used, the programs making them operational, the data of the accounts and the debates of the developers.
The possession of bitcoins is materialized by a series of numbers and letters which constitute a virtual key allowing the expense of the bitcoins associated with it on the register. A person can hold several keys in a "Bitcoin Wallet", a "key ring" web, software or hardware that allows access to the network to perform transactions. The keychain is used to view the balance in bitcoins and public keys intended to receive payments. It also contains (often encrypted) the private keys associated with these public keys. These private keys must remain secret because their holder can spend bitcoins associated with them on the registry. Any media (keyring) is suitable to keep the following symbols constituting your keychain: paper, USB key, memory, etc. With the right software, you can manage your assets on your computer or phone.
To have bitcoins on an account, you need either a bitcoin holder gave you, for example in exchange for a good, or go through a foreign exchange platform that converts conventional currency into bitcoins, or have earned by participating in collective currency control operations.
