Blockchain is a decentralized digital ledger technology that securely records and verifies transactions across a network of computers. Each transaction is grouped into a block, cryptographically linked to the previous one, forming an immutable chain. This ensures transparency, security, and trust without the need for intermediaries like banks. Blockchain underpins cryptocurrencies like Bitcoin and Ethereum but also extends to applications in supply chain management, voting systems, and smart contracts. Its tamper-resistant nature prevents fraud, while its distributed structure enhances reliability. Public blockchains allow anyone to participate, whereas private blockchains restrict access. Consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) validate transactions efficiently. By eliminating central authority, blockchain fosters innovation in finance, healthcare, and beyond, revolutionizing how data is stored and shared globally.
