A new US government report explores how blockchains could be used to track drones carrying medical supplies

Commercial drone delivery is becoming a serious business, but it still faces technical challenges related to data sharing and trust. Blockchains could help with that, a report published April 15 by the US Department of Transportation (DOT) contends. Companies and governments all over the world are using unmanned aircraft systems (UASs) to deliver essential products, like medicines. For instance, last year Ghana launched the world's largest medical drone delivery service, which takes up to 600 on-demand flights per day to 2,000 health facilities spread across the country.
