In a recent article on the website, Security Intelligence, the idea of blockchain is introduced. Security is becoming more of an issue as more and more businesses and individuals are using UAVs. Concerns range from privacy to terrorism. Drones can interfere with large aircraft, take pictures of private spaces, and even deliver explosives and other weapons with devastating effects. Fortunately, technology is being developed to regulate this industry and the se of UAVs. Blockchain can help to organize information, regulate airspace, and protect drones and individuals by providing a type of virtual air traffic control system. How ubiquitous will blockchain become? What other technologies may compete with blockchain? How will agencies like the FAA enforce the use of blockchain by users?
