[0040] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without creative effort are within the scope of protection of this application.

[0041] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0042] The embodiments of this application provide a method and corresponding scheme for managing map navigation based on blockchain. Managing map navigation based on blockchain can make the entire map navigation system available to the public by leveraging the sharing nature of blockchain, allowing users to maintain locations and routes themselves. Blockchain technology is used to determine the deduplication and verification of user-uploaded data, which can effectively maintain a complete map navigation system and allow users to participate in it. Furthermore, by utilizing the security performance of blockchain, it can effectively prevent various forms of attacks. Even if a node is compromised, it can be quickly restored, reducing maintenance costs.

[0043] Figure 1 This is a schematic diagram of a method flow provided in an embodiment of this specification. As shown in the figure, the method includes:

[0044] S101 receives path information sent by the first user, wherein the path information is path navigation information from the starting point to the destination;

[0045] S102 After verifying the path information, it is stored in the blockchain;

[0046] S103 receives a request message sent by a second user, and sends the path information to the second user according to the request message, wherein the request message includes the starting point and the ending point.

[0047] Blockchain is a chain-like data structure that links data blocks sequentially in chronological order, and is a distributed ledger that is cryptographically guaranteed to be immutable and unforgeable. Although the underlying technology of blockchain has been developing for many years, it has not yet been effectively applied in specific scenarios.

[0048] According to a specific embodiment of the present invention, a smart contract for managing map navigation is set on the blockchain. A smart contract is an automated script deployed on the blockchain, and because it is set on the blockchain, it has the characteristics of being public and transparent. Users can pre-set rules through the smart contract to write data to the blockchain and obtain data browsing permissions, thus largely avoiding the disclosure of private information. Of course, smart contracts are not the only implementation method in this application; they are set according to different blockchain platforms, such as Ethereum and Hyperledger.

[0049] According to a specific embodiment of the present invention, in step S101, receiving the path information sent by the first user includes: receiving the path information sent by the first user and verifying the path information using a Merkle tree. It should be noted that this application does not impose any particular limitation on the method of verifying the path information; it can be implemented using a Merkle tree or other methods, such as the UTXO (Unspent Transaction Output) transaction mode to effectively verify whether the data uploaded by the user is genuine.

[0050] In other embodiments of the present invention, receiving the path information sent by the first user may further involve: receiving multiple path information messages sent by the first user, wherein each path information message has the same start and end point; identifying duplicate path information messages; and deduplicating the duplicate path information messages. Specifically, duplicate path information messages are deduplicated using the InterPlanetary File System (IPFS) in the blockchain.

[0051] According to a specific embodiment of the present invention, step S102, storing the verified path information in the blockchain, includes: writing the path information into the blockchain and marking it to distinguish it from first information, where the first information is path navigation information automatically generated by the smart contract based on a map. In practical applications, due to road construction or other circumstances, the path navigation information generated by the smart contract may be temporarily unusable for a period of time, but the path navigation information generated by the smart contract is superior to the path information provided by the user. By marking the path information submitted by the user, the smart contract records the marked information. For example, after a period of time, when the road construction is completed and traffic resumes, the path information is hidden.

[0052] In some preferred embodiments of the present invention, artificial intelligence technology can also be used to determine whether the path information submitted by the user conflicts with the first information. Generally speaking, if it is due to factors such as road construction, the path information submitted by the user will not conflict with the first information. If the artificial intelligence detects a conflict between the two, it can send the path information to the second user.

[0053] According to a specific embodiment of the present invention, an artificial intelligence neural network model can be stored in the blockchain. However, a typical neural network model is large in size, so it can also be stored off-chain.

[0054] Blockchain and off-chain storage have a symbiotic relationship. For certain data, high-value and critical data resides on the blockchain, while low-value and bulky data resides on off-chain storage. Both are linked using a unique identifier. Off-chain storage can store plaintext data or encrypted data. Off-chain encrypted storage involves encrypting the data before storing it on the blockchain, while the key is managed by the blockchain. To decrypt the stored data, authorization must be requested from the blockchain. After obtaining authorization, the decryption key can be obtained, allowing the decryption of the data in the off-chain encrypted storage. It is understood that other data involved in the embodiments of this application can also be stored in off-chain storage; this application does not impose any special restrictions on this.

[0055] According to a specific embodiment of the present invention, in step S103, receiving the request information sent by the second user and sending the route information to the second user according to the request information includes: sending the route information with the lowest road congestion according to the road congestion situation corresponding to each route information. A communication interface can be established between the blockchain and the urban traffic management system, enabling the blockchain to obtain the city's road congestion situation and then select a suitable navigation based on the actual needs of the second user.

[0056] According to a specific embodiment of the present invention, in order to enhance user motivation, a reward system can be established based on blockchain, and each reward is recorded in the blockchain. Specifically, after the path information is stored in the blockchain, a first user associated with the path information is identified, and a reward is sent to the associated first user.

[0057] It is understood that this application does not impose any special restrictions on the first user and the second user. The first user can not only provide path information, but also obtain path information. Similarly, the second user can also provide path information. The first and second are merely provided to facilitate the description of the embodiments of this application.

[0058] According to specific embodiments of the present invention, the settings of blockchain nodes are not particularly limited and can be either map navigation service providers or traffic management departments.
