Bitcoin

Bitcoin is the world's first decentralized cryptocurrency, introduced in 2009 by the pseudonymous Satoshi Nakamoto. It enables peer-to-peer transfer of value over the internet without relying on banks, governments, or any central authority. Transactions are secured and verified through cryptographic proof and recorded on a public, immutable ledger called the blockchain.

The Bitcoin network is maintained by a global network of nodes and miners who use a Proof-of-Work consensus mechanism to validate transactions and secure the chain. With a hard-capped supply of 21 million BTC, Bitcoin is designed to be a scarce, censorship-resistant store of value.

Bitcoin is widely used as a long-term store of value, a medium of exchange, and a treasury asset by individuals, institutions, and corporations around the world. It remains the largest cryptocurrency by market capitalization and the foundational layer-1 blockchain that pioneered the entire digital asset industry.
