The service branch protecting U.S. interests outside the stratosphere may use blockchain to render its computer systems, on earth and in space, unhackable.

• Last week, Xage Security won a contract from the United States Space Force (USSF) to develop and roll out a blockchain-based data protection system across its networks.
• Called the Xage Security Fabric, the blockchain verifies data and protects the network from third party intervention, so confidential data sent from satellites to earth isn't intercepted en-route.
• It also ensures security remains consistent across the entire USSF network, preventing hackers and other malicious entities from identifying and exploiting any weak spots.
• Per a release, Xage's CEO Duncan Greatwood said blockchain allowed USSF to ensure effective domain resilience across all assets and data elements on its network.
• Xage inked a similar agreement with the United States Air Force last December, which wanted to evaluate the Security Fabric platform.
