A public settlement ledger
Thousands of independently operated nodes verify the same transaction history. Miners compete to add blocks, while nodes enforce the network's rules and reject invalid changes.
Protocol profile · Bitcoin
Bitcoin is a decentralized monetary network designed to move and preserve value without a central issuer. Its narrow scope is a feature: settlement first, experimentation second.
Thousands of independently operated nodes verify the same transaction history. Miners compete to add blocks, while nodes enforce the network's rules and reject invalid changes.
New bitcoin enters circulation through block rewards that halve roughly every four years. The fixed maximum supply is enforced by network consensus, not a company promise.
Bitcoin prioritizes censorship resistance, final settlement, and long-term monetary credibility. The Lightning Network can support smaller, faster payments above the base layer.
Proof of work consumes significant energy, base-layer throughput is intentionally limited, and self-custody introduces irreversible responsibility. Its scripting system is less expressive than general-purpose smart-contract networks.
