The network launched on January 3, 2009, when Nakamoto mined the genesis block, creating the first cryptocurrency system to achieve real-world operation. Its core mission is direct electronic payment between independent participants without reliance on banks, payment processors, or centralized monetary authorities. Bitcoin remains the benchmark asset for the broader digital asset market because it combined cryptographic proof, open participation, scarcity, and censorship-resistant settlement into a durable public network. Technically, Bitcoin uses a proof-of-work consensus model secured by SHA-256 mining and a UTXO accounting structure. Transactions are grouped into blocks, miners compete to append valid blocks, and full nodes independently verify the entire rule set from genesis. This architecture gives Bitcoin strong auditability, simple monetary rules, and high resistance to unilateral change. Its development model is conservative, with major protocol changes requiring broad coordination across developers, miners, exchanges, businesses, and node operators. SegWit and Taproot are examples of major upgrades that expanded Bitcoin's transaction and scripting capabilities while preserving backward compatibility. Bitcoin's primary use cases include long-term savings, censorship-resistant settlement, global value transfer, collateral, treasury reserves, and base-layer monetary finality. The ecosystem also includes second-layer infrastructure such as the Lightning Network, which enables faster and cheaper payments through off-chain payment channels. Bitcoin is supported by a deep custody and infrastructure market, including hardware wallets, desktop wallets, mobile wallets, major centralized exchanges, block explorers, analytics services, mining infrastructure, and institutional market products. Its historical milestones include the first known commercial purchase with BTC on May 22, 2010, the emergence of exchange trading in July 2010, and later adoption by corporations, funds, and regulated derivatives markets. Bitcoin's tokenomics are defined by a fixed maximum supply of 21 million BTC and issuance through mining rewards that decline over time through scheduled halvings. The supplied data lists 20.03 million BTC in circulation, equal to about 95.41% of the maximum supply. Bitcoin had no premine, no ICO, no venture allocation, and no founder allocation before public availability; coins were obtained through mining from network launch. This fair-launch distribution, combined with its long operating history and lack of controlling company, is central to Bitcoin's decentralization profile. Governance is informal and off-chain. There is no CEO, no controlling company, and no on-chain DAO voting system. Protocol changes are proposed through Bitcoin Improvement Proposals, implemented in node software, and adopted through social and economic consensus among users, node operators, miners, developers, exchanges, and infrastructure providers. This makes Bitcoin slower to change than many newer networks, but that conservatism is also part of its value proposition: predictable monetary policy, robust backwards compatibility, and resistance to capture by any single organization or executive team.
