The present disclosure relates to a method and apparatus for recording mileage data of a vehicle on a blockchain. A method for recording mileage data of a vehicle on a blockchain is provided, including: providing a vehicle database and a mileage database, where the vehicle database is configured to store an identification number that uniquely identifies a vehicle, and the mileage database is configured to store mileage data about vehicle kilometers of travel (VKT); obtaining a vehicle identification number (VIN) from the vehicle database; obtaining the mileage data of the vehicle from the mileage database according to the VIN; and storing data related to the mileage data in the blockchain.

Method and apparatus for recording mileage data of vehicle on blockchain

Methods and devices are provided for uploading driving data to a blockchain network. The method is executed at a vehicle node in the blockchain network and includes: packing driving data of the vehicle node within a predetermined time interval every predetermined time interval to obtain a vehicle data packet of the vehicle, and storing the vehicle data packet locally in the vehicle node; broadcasting the vehicle data packet to other vehicle nodes located nearby and in the blockchain network for the other vehicle nodes to receive and store; receiving and storing other vehicle data packets broadcast by the other vehicle nodes located nearby and in the blockchain network; and when connecting to a fixed node that belongs to the blockchain network, synchronizing the vehicle data packet and the other vehicle data packets as stored to the fixed node, wherein the fixed node participates in the consensus of the blockchain network.

Blockchain-based method and device for processing driving data

A method is disclosed for implementing trust Internet of Things (IoT) services in an IoT device and a user device. The IoT device receives from the user device an authentication request comprising a hash value, first encrypted information and second encrypted information, where the IoT device determines whether the user device is successfully authenticated based on determining the user device public key and confirming that the user device public key exists in a list of access permitted user devices of the IoT device.
