Blockchain is a decentralized, distributed ledger technology that records transactions across a network of computers.
Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant's ledger. This creates a chain of blocks, or a blockchain, that is secure, transparent, and resistant to modification. Blockchain technology is most commonly associated with cryptocurrencies like Bitcoin, but its potential applications go far beyond digital currencies. It can be used to securely record transactions in industries such as finance, supply chain management, healthcare, and more, revolutionizing the way we store and exchange value and information.
