Bitcoin Network

The Bitcoin Network is a peer-to-peer system for transferring and recording value. It has no central operator, no headquarters, and no single point of failure. Participants run software that follows a shared set of rules. When those rules are followed, transactions can be broadcast, verified, and recorded on a public ledger known as the Bitcoin blockchain.

Anyone can join the network by running a full node. A node downloads and verifies the entire history of the chain. It rejects blocks or transactions that violate the consensus rules. Miners propose new blocks by performing proof-of-work. Users create transactions with private keys. No single participant controls the others. The network continues as long as participants choose to run the software and follow the rules.

The design prioritizes censorship resistance and open access over speed or simplicity. Settlement finality is probabilistic and improves as more blocks are added on top of a transaction. The network does not require identity, permission, or geographic proximity. It only requires that a transaction be valid according to the rules enforced by the nodes that choose to participate.
