• Transactions are grouped into blocks and added to the chain in chronological order.
• Each block is secured using cryptographic hashes and consensus mechanisms.
• Blockchain enables trustless peer-to-peer transactions without a central authority.
• It’s used in crypto, smart contracts, DeFi, and other emerging technologies.
