Blockchain is a register with decentralized distribution in which all of a network's transactions are saved. Here, several transactions are collated in one block and the blocks are linked together chronologically. What is crucial is that the correctness of a piece of information no longer needs to be verified by a central authority, but is confirmed using a transparent mechanism of consensus between the participants. Blockchain technology thus supports cooperation across the organization along the entire value chain.
Blockchain technology can be used in all areas where large-scale and comprehensive exchange of data takes place to maintain data integrity.
