Bitcoin birthed the concept of blockchain technology, and now even organizations as technologically advanced as NASA are considering its benefits. Yet cryptocurrency is often described as a fad, a bubble, and even worthless.
Ronald J. Reisman, an aero-computer engineer at the NASA Ames Research Center, has put forward blockchain to solve issues of privacy and the prevention of spoofing, denial of service, and other attacks.
He says a new system due for implementation in 2020, the Automatic Dependent Surveillance-Broadcast (ADS-B), does not provide for the protection of flight plans and positions and other state data. Reisman believes blockchain has the answer in the form of an engineering prototype built using a permissioned blockchain.
