  Currently, drones represent a promising technology for combating Coronavirus
disease 2019 (COVID-19) due to the transport of goods, medical supplies to a
given target location in the quarantine areas experiencing an epidemic
outbreak. Drone missions will increasingly rely on drone collaboration, which
requires the drones to reduce communication complexity and be controlled in a
decentralized fashion. Blockchain technology becomes a must in industrial
applications because it provides decentralized data, accessibility,
immutability, and irreversibility. Therefore, Blockchain makes data public for
all drones and enables drones to log information concerning world states, time,
location, resources, delivery data, and drone relation to all neighbors drones.
This paper introduces decentralized independent multi-drones to accomplish the
task collaboratively. Improving blockchain with a consensus algorithm can
improve network partitioning and scalability in order to combat COVID-19. The
multi-drones task is to combat COVID-19 via monitoring and detecting, social
distancing, sanitization, data analysis, delivering goods and medical supplies,
and announcement while avoiding collisions with one another. We discuss End to
End (E2E) delivery application of combination blockchain and multi-drone in
combating COVID-19 and beyond future pandemics. Furthermore, the challenges and
opportunities of our proposed framework are highlighted.
