According to the announcement of the National Intellectual Property Administration, Tencent Technology (Shenzhen) Co., Ltd. applied for a patent called "Blockchain On-Chain Method, Related Devices and Media", with publication number CN117354324A, and the application date was October 2023. The patent abstract shows that this disclosure provides a method, related devices and media for blockchain on-chain. The method is applied to the first consensus node in the blockchain network, which includes not only the first consensus node but also the second consensus node. The method includes: obtaining multiple batches of transactions to be put on the chain, each batch of transactions to be put on the chain includes multiple transactions of a consensus node in multiple consensus nodes; for each batch of transactions to be put on the chain, packing the transaction indexes of multiple transactions to be put on the chain in the batch of transactions to be put on the chain into a pre-generated block; broadcasting the pre-generated block to the second consensus node, so that the second consensus node can obtain the transactions to be put on the chain based on the transaction indexes and give consensus feedback to the first consensus node based on the obtained multiple transactions to be put on the chain; based on the consensus feedback of the second consensus node, packing the transactions to be put on the chain into the target block to be put on the chain. This disclosure can improve the efficiency of transaction on-chain. This disclosure can be applied to various scenarios such as blockchain, artificial intelligence, and cloud technology.

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.
