Blockchain is a technology that allows data to be stored and exchanged on a peer-to-peer1 (P2P) basis. Structurally, blockchain data can be consulted, shared and secured thanks to consensus-based algorithms2. It is used in a decentralised manner and removes the need for intermediaries, Termín blockchain je v posledních třech letech trochu nadužívaný, obzvlášť na konferencích plných lidí v na míru šitých oblecích o něm uslyšíte na každém rohu. Co to ten blockchain ale vlastně je?
