Blockchain is a relatively new technology with enormous potential in various areas of aviation. Even though there is currently no market-ready blockchain application that permanently changes the value chain of airlines, the topic is gaining momentum and numerous players are increasingly testing new solutions in this area. This is also reflected in the enthusiastic response to the world’s first Aviation Blockchain Challenge, which the Lufthansa Innovation Hub and SAP.iO Foundry jointly announced in July. Over the six-week submission period, teams from 56 countries submitted a total of 312 blockchain ideas.
