What is blockchain

Blockchain is a decentralized and distributed technology that provides data recording and storage in the form of a block chain. Each block contains a set of transactions, a timestamp and a hash of the previous block, which ensures data integrity and security. The blockchain works on a network of nodes where each participant has access to the same version of the registry, which eliminates the possibility of manipulation. This system is used in cryptocurrencies, and also finds application in various fields: finance, logistics, supply chain management and even in healthcare. Blockchain provides transparency, reliability and avoids intermediaries, which makes it a revolutionary technology.
