Blockchain is a system of storing and transferring information in a distributed and decentralized way. You can think of it as a ledger or a record book that is shared and updated by many participants, instead of being controlled by a single authority. Each entry or transaction in the ledger is verified and encrypted by a network of computers, called nodes, using cryptography. These transactions are grouped into blocks, and each block is linked to the previous one by a unique code, called a hash. This creates a chain of blocks, or a blockchain, that is secure, transparent, and immutable.
