How Bitcoin Works: The Blockchain Architecture
Bitcoin operates on a blockchain - a chain of "blocks" containing groups of transactions ordered sequentially. The blockchain serves as a public, distributed ledger that permanently records all transactions.
Key components of Bitcoin's architecture include:
- Nodes: Computers that participate in the network by validating and relaying transactions
- Miners: Special nodes that compete to produce new blocks and earn rewards
- Transactions: Transfers of Bitcoin between addresses, secured by cryptographic signatures
- Blocks: Groups of transactions that are added to the blockchain approximately every 10 minutes
Consensus Rules: The protocols determining how the network reaches agreement on transaction validity
