The Evolution of Blockchain

Blockchain technology emerged in 2008 with the launch of Bitcoin, designed as a decentralized, peer-to-peer currency that allowed individuals to send value directly to one another without intermediaries like banks or payment processors. Bitcoin's innovative use of cryptography and distributed ledger technology (DLT) created a trustless system, where no single entity controlled the network, and all participants could rely on cryptographic proof to verify transactions.

Since then, blockchain has evolved far beyond its original use case of digital money. The underlying technology has become the backbone of many decentralized applications (dApps), giving rise to new concepts such as smart contracts, decentralized finance (DeFi), non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs). Blockchain has transformed industries ranging from finance and supply chain to healthcare and entertainment.
