General Motors Files Patent for a Blockchain-Based Navigation Map

Major car manufacturer, General Motors, or GM, has filed a patent application for a continuously updating navigation map system. The system would use blockchain to integrate data from vehicle sensors and build a reliable map for autonomous vehicles.

According to the filing, which was submitted on Oct. 1, 2018 and published on April 2, 2020, existing maps are “difficult to keep dynamic without incurring large costs.”One potential reason for this is that most maps are maintained through specialized vehicles, whose reach will necessarily be limited to just a few specific sections of the world.

General Motors’ solution is to distribute the process to many vehicles, which would collect data about their surroundings through sensors as they simply drive around.The real-time data would be compared with a discrepancy detector, which analyzes the existing maps.
