The invention relates to a method and a device for processing driving data based on a block chain. The invention provides a method for uploading driving data to a block chain network, and the method is executed at a vehicle node belonging to the block chain network, and comprises the steps: carrying out the packaging of the driving data of the vehicle node in a preset time interval at a preset time interval, so as to obtain a vehicle data package of a vehicle, and locally storing the vehicle data packet in the vehicle node; broadcasting a vehicle data packet to other nearby vehicle nodes belonging to the block chain network, so that the other vehicle nodes can receive and store the vehicle data packet; receiving and storing other vehicle data packets broadcasted by other vehicle nodes belonging to the block chain network nearby; and when a fixed node subordinate to the block chain network is connected, synchronizing the stored vehicle data packet and other vehicle data packets to the fixed node so as to be li
