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

Quick Take

  • Commercial drone delivery is seeing serious adoption around the world, but technical issues around data sharing and trust remain
  • Blockchain-based flight recorders and other similar systems could open the door to more advanced applications, according to a new report published by the US Department of Transportation.

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.

"The number of variety of UASs and the diverse operations they are or may be expected to soon be involved in make these aircraft especially suitable to the trust and operational integrity provided by blockchains," says the DOT report, which was penned by a group of contributors led by engineer Seamus McGovern of the John A. Volpe National Transportation Systems Center. The DOT's website describes the report as "a high-level study of unmanned aircraft systems' flight operations that may benefit from the application of blockchain concepts."

A "blockchain-based black box," for example, might provide data that would help investigators figure out what a drone was doing right before it crashed or failed. The report notes that IBM has obtained a patent for a system that would use a blockchain to help air traffic controllers chronicle each drone's flight path, and even respond in real-time if, say, the drone drifts too close to a restricted flight zone. 

For a more concrete example, consider a drone that is supposed to deliver a human organ for a transplant. This has already happened; in 2019 a drone delivered a kidney that was then successfully transplanted, at the University of Maryland. The kidney flew 2.6 miles in 10 minutes over the city of Baltimore, whereas a car trip would have taken 15-20 minutes.

"Not only is time an issue, but another concern is that en route the organ's progress is not normally known by the receiving hospital," and this lack of clarity can lead to unnecessary delays, notes the DOT report. In theory, adding a blockchain to the process would let all the entities involved – air traffic controllers, the drone operator, the drone itself, the hospital supplying the organ, and the hospital that is receiving it – track an important set of shared data.

They could have varying levels of access to the ledger, which might track the drone's position, its intended route, its fuel status, and essential information about the organ itself and its container.

"In this case study, not only is a range of valuable information readily available, but it is also trusted, which is critical in both aviation operations and medical procedures," the report concludes.
