Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system. Bitcoin transactions are secured by mathematics and energy. Cryptographic signatures prevent other people from spending your money. Energy spent by proof of work (PoW) prevents other people from undoing, rearranging or losing your transactions. So long as you take the required steps to protect your wallet, Bitcoin can give you control over your money and a strong level of protection against many types of fraud.

Bitcoin Core is programmed to decide which block chain contains valid transactions. The users of Bitcoin Core only accept transactions for that block chain, making it the Bitcoin block chain that everyone else wants to use. It is these users who keep Bitcoin decentralized. They individually run their own Bitcoin Core full nodes, and each of those full nodes separately follows the exact same rules to decide which block chain is valid. There's no voting or other corruptible process involved: there's just individual software following identical rules—"math"—to evaluate identical blocks and coming to identical conclusions about which block chain is valid. Bitcoin Core ensures every block and transaction it accepts is valid, increasing not only your security but also helping prevent miners and banks from taking control of Bitcoin. Bitcoin Core provides exclusive privacy features that can make it hard for anyone to link you to your transactions.
