When the Internet of Vehicles meets the blockchain, what kind of reaction will it produce?

In the movie "The Fast and the Furious", there is a plot that describes the top hackers hacking into the sensing systems of thousands of cars, and remotely controlling these cars to automatically rush to the streets of New York...

recent,

recent,Volkswagen has applied for a patent, allowing vehicles to communicate with each other through a blockchain-based network, aims to alert drivers to potential dangers by monitoring information from nearby vehicles.

In fact, as early as 2014, V2V communication technology has appeared, which can monitor the speed and position of other vehicles driving on the street. Through a wireless broadcasting system connected to Wi-Fi, it can automatically remind the driver of the vehicle in the blind spot. There will be a red light on the instrument display to make the driver react in time.

Although Volkswagen's patent does not describe its specific application scenarios, Ford Motor Company has already given an answer in advance. The CMMP system developed by it is a car networking platform that combines blockchain technology and token economy.

According to Ford'spatent applicationIt is shown that these vehicles will first be equipped with adaptive cruise control technology (CACC). The distance sensor installed in the front of the vehicle will continuously scan the road ahead of the vehicle, while the wheel speed sensor will collect the speed signals of nearby vehicles. When the distance to nearby vehicles is too small, CACC technology can properly brake the wheels and reduce the output power of the engine so that the vehicle can always maintain a safe distance from nearby vehicles.

When there is a traffic jam, the CMMP system broadcasts information to all vehicles. According to the real-time geographic location information of the vehicles, the vehicles will be automatically formed into a fleet, and they will drive at a consistent speed while maintaining the traffic flow. However, if a car owner is willing to spend the tokens on the CMMP platform, he can "jump the queue" and enter the lane with priority. One token, can be prioritized for 10 seconds.

In the future, the combination of blockchain and Internet of Vehicles may have more applications. Such as automatic execution of transactions, decentralized recording of information, protection of car owner privacy, etc. To give a few examples:

First, the ecological chain of the Internet of Vehicles includes auto repair and accessories, vehicle management, car manufacturers, car rental, insurance, etc. Smart contracts can realize the automatic execution of transactions.

Second, the license plate, as the unique account number and identification of the car, is connected to the blockchain system. Due to the non-tamperability of the blockchain, violation information and on-site information of traffic accidents will be permanently recorded in the blockchain, so that evidence can be solidified.

Third, in addition to the vehicle's own information, the owner's information including personal privacy, driving habits and behavior pattern information will be gathered to the central processing unit. This may encounter the scenario mentioned at the beginning, where the vehicle is controlled by hackers, causing an accident, and the car owner may face the danger of data leakage. The characteristics of the decentralized and decentralized records of the blockchain make it less likely for hackers to attack, which ensures the safety of the road; and the anonymous recording method of the blockchain will also effectively protect personal privacy.

Of course, blockchain technology also has some unsolvable problems, such as network transmission delays, etc. These problems may require cloud computing to achieve. Moreover, the combined use of the Internet of Vehicles and the blockchain requires the support of users all over the world. Because some users may not be willing to access Ford's CMMP system, while some users accept the CMMP system. So how should the system dispatch vehicles so that they form an orderly traffic flow during traffic jams?
