The experimental trial was conducted at NASA’s Ames Research Center in California, where an Alta-X drone was used to demonstrate how blockchain technology can secure real-time communication between aircraft and ground control stations. The test showed that decentralized digital ledgers could safeguard sensitive aviation data against increasingly sophisticated cyber threats.
According to NASA, the new system goes beyond traditional cybersecurity measures by ensuring that critical information — including flight plans, telemetry data, and operator credentials — remains accurate, verifiable, and accessible only to authorized users. Once recorded on the blockchain, the data becomes virtually impossible to alter without detection.
The flight test, carried out in August under simulated real-world conditions, relied on a custom-built combination of hardware and software. Using an open-source blockchain framework, the system successfully processed high-speed digital transactions, proving its ability to meet the demanding security requirements of modern and future air traffic systems.
Researchers believe the technology could play a crucial role in next-generation aviation, particularly in Urban Air Mobility, drone operations, and autonomous aircraft flying at altitudes above 60,000 feet.
By demonstrating that blockchain can securely transmit and store aviation data in real time, NASA is laying the groundwork for a trusted, scalable cybersecurity framework that could redefine safety standards for the future of flight.
