Volkswagen developed an inter-vehicular blockchain system to increase road safety and prevent incidents. The system will unite nearby vehicles in a network allowing them to communicate with each other and notify drivers of potential collisions:
“In Vehicle-to-Vehicle communication messages are exchanged between vehicles to enable novel safety-relevant use cases. Most of the currently known use cases provide warnings to alert a driver about an imminent event, such as two vehicles colliding with each other,” the patent’s excerpt explains. The messages will be cryptographically signed, and information stored on Blockchain.
