A decentralized and distributed technology for storing and transmitting information, which allows for the creation of immutable and secure digital records of transactions and other data. It is a system in which information is stored in blocks, and each block contains transaction data, information about the time and order of transactions, and a unique verification code. The blocks are then linked together in a chain, creating a continuous and unalterable history of transactions. Blockchain is protected against external interference by advanced cryptographic techniques and data distribution across multiple computers in the network, making it very secure and difficult to falsify. Blockchain is used in many fields, including cryptocurrencies, logistics, supply chain, law, medicine, and many others.
