In 2025, NASA researchers at Ames Research Center conducted drone-based tests of a blockchain system designed to protect flight data from tampering or interception. The decentralized blockchain framework allowed real-time, secure sharing and storage of aircraft registration, flight plans, and telemetry data among trusted users, aiming to counter evolving cyber threats in aviation.
The successful demonstration on an Alta-X drone showed potential applications across various aviation domains, including autonomous air traffic and urban air mobility. While results are promising, further analysis is underway to evaluate resilience and scalability before broader deployment in safety-critical aviation systems.
