Bitcoin
Protocol
Decentralized digital money secured by proof of work.
Bitcoin is a network and asset designed for peer to peer electronic cash. It uses proof of work to secure a public ledger and a fixed supply that caps issuance at 21 million BTC. Anyone can run a node to verify the rules and validate their own transactions. People use Bitcoin to store value and send payments globally. Fees vary with demand, and final settlement happens on the base chain. Learn how addresses and confirmations work before you move larger amounts, and keep secure backups of your wallet.
