Blockchain is a revolutionary technology underpinning cryptocurrencies like Bitcoin. It operates as a decentralized ledger where transactions are recorded across a network of computers. Each transaction forms a "block" linked cryptographically to the previous one, creating an immutable chain. This transparency and security make blockchain appealing beyond finance, impacting sectors like supply chain management, healthcare, and voting systems.
