Tencent Technology (Shenzhen) Co., Ltd. has obtained a patent for a "vehicle management method, device, terminal, and storage medium based on blockchain", with authorization announcement number CN110889520B and application date of November 2019. The patent abstract shows that this application example discloses a vehicle management method, device, terminal equipment, and storage medium based on blockchain. The method includes: the vehicle management node obtains parking information of the vehicle, obtains the corresponding vehicle information of the vehicle from the blockchain based on the hash value of the license plate in the parking information; obtains the vehicle service points within the distance threshold range of the parking lot location and pushes the vehicle service orders corresponding to the vehicle service points to the user terminal; obtains the vehicle service reservation information returned by the user terminal and the first signature information of the vehicle service reservation information by the user terminal. If the consensus node in the blockchain network reaches a consensus on the vehicle service reservation information, the service reservation block containing the vehicle service reservation information is added to the blockchain, and the parking discount information is sent to the user terminal. By using this application example, the flexibility of selecting vehicle service points can be improved, and the accuracy of recommending vehicle services can be improved.
