Introduction
Blockchain technology has evolved far beyond its cryptocurrency origins, transforming industries from healthcare to supply chain management. While Bitcoin introduced decentralized digital money, blockchain’s potential extends to secure data sharing, smart contracts, and tamper-proof record-keeping. This comprehensive guide explores how blockchain is revolutionizing sectors beyond finance, its real-world applications, and what the future holds for this groundbreaking technology.
A. Understanding Blockchain’s Core Capabilities
