A blockchain is a decentralized, distributed ledger technology that securely records transactions across a network of computers. Each block contains a timestamped list of validated transactions. Once a block is added to the chain, it is extremely difficult to alter, ensuring data integrity and transparency. This innovative technology underpins cryptocurrencies like Bitcoin and has applications far beyond digital currencies, including supply chain management and secure data sharing due to its inherent security and immutability.
