Bitcoin is an open-source, decentralized digital currency and peer-to-peer payment network that enables permissionless transactions without a central authority. It uses a distributed ledger (blockchain) and collective network validation to issue and record bitcoins, offering global payments, low processing fees, and censorship resistance. Bitcoin is maintained by a community of developers and contributors; resources such as Bitcoin. org provide wallets, documentation, developer guides, and tools for running full nodes and participating in the network.
