About
Blockchain is a distributed ledger technology in which records (blocks) are cryptographically linked and distributed across a network of computers, making them effectively immutable and transparent without requiring a central authority. Bitcoin, created by Satoshi Nakamoto in 2009, was the first major blockchain application — enabling peer-to-peer digital currency transactions without banks.
Ethereum (2015) introduced smart contracts — self-executing code on the blockchain — enabling NFTs, DeFi (decentralized finance), and DAOs. The total cryptocurrency market has reached over $2 trillion in value. Beyond finance, blockchain applications include supply chain tracking, healthcare records, voting systems, and digital identity verification.
