NASA Publishes Proposal for Air Traffic Management Blockchain Based on HyperLedger
The United States National Aeronautics and Space Administration (NASA) has proposed an air traffic management blockchain, according to a paper published on the agency’s official website on Jan. 10. The proposed system would employ an open-source permissioned blockchain to enable secure, private and anonymous communication with air traffic services. The document notes:
The engineering prototype of the system reportedly employed the Hyperledger Fabric and demonstrated that such infrastructure could be rapidly deployed and economically maintained.
In December of last year, Hyperledger — an open source project created by the Linux Foundation and created to support the development of blockchain-based distributed ledgers — onboarded 12 new members, including such major firms as Alibaba Cloud, Citi and Deutsche Telekom. According to the document, the Automatic Dependent Surveillance System (ADS-B) — which will be mandatory by 2020 — is subject to third-party spoofing as it publicly broadcasts aircraft positions. Furthermore, the proposal explains the difficulties of such solutions:
According to the proposal, enterprise blockchain solutions could be a practical PKI for aircraft applications.
Such a system, according to the paper, would “enable ADS-B systems to meet or exceed the same level of privacy and security currently provided by radar-based systems in the NAS. “
As Cointelegraph reported in August 2018 in an analysis dedicated to blockchain in space NASA had awarded a $330,000 grant in 2017 that supported the development of an autonomous, blockchain-based spacecraft system, making its first move toward blockchain adoption. Also, in December of last year, news broke that blockchain development firm Blockstream has expanded its satellite service with the fifth satellite and is now broadcasting the Bitcoin (BTC) blockchain to all of Earth’s major land masses.
