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.
