What Is Bitcoin and How Does It Work?
Bitcoin is an open-source, peer-to-peer digital currency network that allows users to send and receive value without relying on a central authority. Its transactions are processed by miners, who use computing power to validate activity and secure the blockchain.

Why it matters
Transactions on the Bitcoin network are handled through a global system of nodes and miners. Nodes maintain copies of the blockchain, including its history of previous transactions, while pending transactions are distributed across the network. Miners use computational power to solve cryptographic puzzles, helping validate transactions and add new blocks to the chain.
Bitcoin is designed as a decentralized network for transferring value directly between users. Unlike a traditional banking system, it does not depend on a central authority to approve transactions, manage access, or control monetary supply. Its code is open source, meaning anyone can review it, and developers with the right expertise can propose improvements.

Miners are compensated through block rewards. According to the source material, after Bitcoin’s 2020 halving, the reward stood at 6.25 BTC. Bitcoin’s design, described in Satoshi Nakamoto’s whitepaper, includes a reward schedule that halves roughly every four years.
Bitcoin is often discussed for its ability to operate without intermediaries and for giving users direct control over their funds. The source also notes that some have framed Bitcoin as an inflation hedge, though that narrative has faced scrutiny, including during the period when U.S. inflation reached 7.5% in January 2022. For users who buy Bitcoin through an exchange, the source emphasizes the importance of understanding wallet custody, since controlling a wallet’s private key means controlling access to the funds.
