A blockchain is a distributed database implemented in a number of nodes, where each node automatically verifies all changes and additions made in any of the other nodes. The original blockchain was designed to guarantee the authenticity of the electronic currency bitcoin. Today, we see many new applications of the blockchain, for example in the Internet-of-Things (IoT) domain, where it is often essential to ensure that all sensors and control means are authorized (such as in autonomous vehicles and in medical surveillance).
