【Abstract】Blockchain is the consensus-based technology used to resolve conflicts in Byzantine environments. Vehicles validate the messages received from neighboring vehicles using the gradient boosting technique (GBT). Based on the validation results, the message source vehicle generates the ratings that are to be uploaded to roadside units (RSUs), and through that, the trust offset value can be calculated. All RSUs maintain the trust blockchain, and each RSU tries to add their blocks to the trust blockchain. We proposed a blockchain-based trust management model for the vehicular adhoc network (VANET) based on Tendermint. It eliminates the problem of malicious nodes entering the network, and will also overcome the problem of power consumption. Simulation results also show that the proposed system is 7.8% and 15.6% effective and efficient in terms of packet delivery ratio (PDR) and end-to-end delay (EED), respectively, to collect the trusted data between the vehicles.
