Lightweight blockchain inherits the advantages of traditional blockchain, while avoiding excessive reliance on computing and storage resources, and has already been applied in IoV system. This paper combines the characteristics of IoV and node distribution, and proposes a lightweight blockchain architecture oriented to vehicles-road-cloud-server(V2R2CS) collaboration based on the existing lightweight blockchain architecture. Cooperating caching and Block Filtered Algorithm are used to allow road side units(RSUs) to cooperatively store and search blocks, which will further reduce the delay of blockchain query in IoV system. Finally, the simulation experiment proves the feasibility of the algorithm and the good real-time requirement.
