Bitcoin is the world's first and most widely accepted cryptocurrency. It was introduced in 2009 by an anonymous individual known as Satoshi Nakamoto. Bitcoin is basically a computer money with no central authority, which facilitates peer-to-peer transactions on a decentralized network. Its invention opened the gates to a new era of finance—one that would allow people to transfer value without middlemen like banks and governments.

Bitcoin operates on an innovation known as blockchain. Blockchain is a public record that stores every transaction ever done using Bitcoin. When one sends Bitcoin to another user, the transaction is authenticated by a network of computers known as miners. The miners compute intricate mathematical equations to ensure that the transaction is valid. Once authenticated, the transaction is incorporated into the blockchain.

Bitcoin is created by the mining process. New bitcoins are given to miners as reward for being in the position to successfully validate transactions. But Bitcoin supply is capped at 21 million coins, making it scarce—like gold. That scarcity is part of the reason that Bitcoin is considered to be a store of value by so many.
