Introduction
Bitcoin is a groundbreaking decentralized digital currency that enables instant, borderless payments worldwide. Operating on peer-to-peer technology, it eliminates the need for central authorities, with transactions and money issuance managed collectively by the network. Originally developed by Satoshi Nakamoto and released under the MIT license, Bitcoin represents the first successful implementation of a distributed cryptocurrency, combining cryptography, economic principles, and technological innovation.
