This is the author accepted manuscript. The final version is available from IEEE via the DOI in this record5G-enabled drones have potential applications in a
variety of both military and civilian settings (e.g., monitoring
and tracking of individuals in demonstrations and/or enforcing of social / physical distancing during pandemics such as
COVID-19). Such applications generally involve the collection
and dissemination of (massive) data from the drones to remote
data centres for storage and analysis, for example via 5G
networks. Consequently, there are security and privacy considerations underpinning 5G-enabled drone communications. We
posit the potential of leveraging blockchain to facilitate privacy
preservation, and therefore in this article we will review existing
blockchain-based solutions after introducing the architecture for
5G-enabled drone communications and blockchain. We will also
review existing legislation and data privacy regulations that need
to be considered in the design of blockchain-based solutions, as
well as identifying potential challenges and open issues which
will hopefully inform future research agenda
