Blockchain system (or blockchain)

Decentralized and distributed technology, which is a chain (chain) of blocks in which data is recorded and stored with a high degree of reliability and without the possibility of changing it. Blockchain was originally created to support cryptocurrencies such as Bitcoin, where each block represents a group of transactions. However, over time, blockchain has found wide application in various fields where it is necessary to ensure decentralized and secure recording and transmission of data. Due to its characteristic of reliability and the impossibility of changing past records, blockchain allows sustainable recording, verification and auditing of transactions and events in various industries such as finance, logistics, healthcare and many others.
