Blockchain is a decentralized, digital ledger that records transactions across multiple computers in a secure, transparent, and tamper-proof manner. It consists of “blocks” containing transaction data, cryptographically linked to form a “chain.” Once added, data cannot be altered without consensus from the network. This eliminates the need for intermediaries like banks, ensuring trust through algorithms and cryptography. Blockchain powers cryptocurrencies like Bitcoin, but its applications extend to supply chain management, smart contracts, and decentralized finance (DeFi). By providing transparency, immutability, and security, blockchain revolutionizes how data is stored, shared, and verified in various industries.
