Bitcoin (BTC) is the world's first decentralized digital currency, created in 2009 by the pseudonymous Satoshi Nakamoto. As a cryptocurrency, Bitcoin uses cryptographic principles to ensure secure and anonymous transactions. Unlike traditional currencies, it operates without central authority—governed by a global network of users. Bitcoin has sparked worldwide interest, attracting investors and tech enthusiasts alike.
The Origin and Evolution of Bitcoin
Bitcoin’s concept debuted on October 31, 2008, when Nakamoto published the whitepaper Bitcoin: A Peer-to-Peer Electronic Cash System, outlining its design and mechanics. On January 3, 2009, Nakamoto mined the "genesis block", launching the Bitcoin network.

How Bitcoin Works: Core Principles
