Review of Blockchain in Internet of Vehicles

In view of the challenges of security,trustworthiness and data sharing faced by Internet of Vehicles(IoV)systems,blockchain technology is introduced to enhance the security and collaborative sharing capability of IoV.The overview of blockchain technology is given from two aspects of features and technical architecture.Combining the features of decentralized storage,consensus-based security and data immutability of blockchain,the complementary advantages and research status of the cooperative application of blockchain and edge computing are discussed.Then,the application direction and current researches of blockchain in IoV system are analyzed from the perspective of synchronization,security and data sharing.Finally,the development trend of blockchain in IoV is pointed out that the future blockchain technology will promote the evolution and development of IoV from single vehicle intelligence to group intelligence and from single point traffic control to regional linkage control from the perspectives of vehicles and roads.The integrated application of blockchain and IoV enhances the security and data sharing of IoV,which will further promote the deep integration of automobile,transportation and communication industries and accelerate the development of IoV technology.
