[0057] The following uses a cross-platform rights and interests user transaction device based on blockchain technology as an example of an execution subject to illustrate the implementation process of the cross-platform rights and interests user transaction method based on blockchain technology provided by an embodiment of the present invention. It is understandable that the execution subject of the cross-platform rights and interests user transaction method based on blockchain technology provided by an embodiment of the present invention includes but is not limited to a cross-platform rights and interests user transaction device based on blockchain technology.

[0058] Figure 1 A flowchart of a user transaction method for cross-platform rights and interests based on blockchain technology provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method includes:

[0059] Step 101: Obtain user transaction information through cross-platform user association relationships, where the user transaction information includes a user identifier.

[0060] Step 102: Through blockchain technology, according to the user ID, query the corresponding user rights and interests data, where the user rights and interests data is the rights and interests data of the user in multiple trading platforms stored on the blockchain.

[0061] Step 103: Verify the user rights and interests data according to the user transaction information.

[0062] Step 104: If the user rights data verification is passed, cross-platform rights exchange is performed based on the user rights data to complete the user transaction.

[0063] In the technical solution provided by the embodiment of the present invention, user transaction information is obtained through cross-platform user association relationships, and the user transaction information includes a user identifier; through blockchain technology, the corresponding user rights and interests data is queried according to the user identifier, and the user rights and interests data is the rights and interests data of the user under multiple transaction platforms stored on the blockchain; the user rights and interests data is verified according to the user transaction information; if the user rights and interests data is verified, cross-platform rights and interests are exchanged according to the user rights and interests data to complete the user transaction, which can reduce the user's operation complexity, reduce the user's ability requirements, enhance the convenience of using the rights and interests data of the life service platform, and improve the user experience; by automatically performing cross-platform rights and interests exchange, there is no need for frequent data interaction with users, and the rights and interests exchange speed is increased, thereby improving transaction efficiency; at the same time, the user rights and interests data is stored through the blockchain, and with the help of the high security and privacy protection characteristics of the blockchain smart contract, the risk of user privacy leakage is reduced, and the security of user privacy data and user rights and interests data is guaranteed.

[0064] Figure 2 A flowchart of another cross-platform rights and interests user transaction method based on blockchain technology provided by an embodiment of the present invention is as follows: Figure 2 As shown, the method includes:

[0065] Step 201: Obtain user registration information of each trading platform, where the user registration information includes a user ID.

[0066] In the embodiment of the present invention, each step is performed by a cross-platform rights and interests user transaction device based on blockchain technology.

[0067] In the embodiment of the present invention, the trading platform is a platform developed by a financial institution, and users can purchase and use coupons between trading platforms.

[0068] In the embodiment of the present invention, the user registration information includes but is not limited to the user ID, gender, work unit and date of birth. The user ID can uniquely identify a user. As an optional solution, the user ID is a mobile phone number or an ID card number. The same user can register on multiple platforms or apps using the same user ID.

[0069] Step 202: According to the user identifier, the user registration information of each trading platform is associated to obtain a cross-platform user association relationship.

[0070] In an embodiment of the present invention, the interface provided by each trading platform and APP to the financial institution is called to obtain the user registration information of each trading platform and APP; according to the user identifier, the user registration information of the same user identifier is associated, so that the same user can be associated with each other on each trading platform and APP. When the user purchases rights and interests from one of the trading platforms or APPs and needs to use them from another trading platform or APP, they can be automatically redeemed across platforms.

[0071] Step 203: Receive user rights and interests transaction information from each trading platform.

[0072] In the embodiment of the present invention, user rights and interests transaction information is the transaction information of the user purchasing rights and interests on the trading platform, and the user rights and interests transaction information includes but is not limited to rights and interests information, user key pairs and user identification. Rights and interests information includes rights and interests coupon code and rights and interests details information; user key pairs include user private key and user public key generated by the trading platform as user identity; user identification can uniquely identify a user, and as an optional solution, the user identification is a mobile phone number or ID number.

[0073] It is worth noting that each equity voucher code is associated with a user ID so that available equity can be queried in subsequent transactions.

[0074] Step 204: Generate user rights and interests data based on the user rights and interests transaction information.

[0075] In the embodiment of the present invention, the user rights and interests transaction information includes but is not limited to rights and interests information, user key pairs and user identification.

[0076] In the embodiment of the present invention, a unique rights and interests identifier is generated for each user rights and interests transaction information, and one rights and interests identifier uniquely identifies one user rights and interests transaction information. The user rights and interests data is the user's rights and interests data under multiple trading platforms.

[0077] In the embodiment of the present invention, step 204 specifically includes:

[0078] Step 2041: Generate a proof of rights and interests based on the rights and interests information and a random number selected by the user.

[0079] Specifically, the user selects a random number r and generates a proof of interest through proof = ZoKratesProve (statement, r), where r is a random number, proof is the proof of interest, ZoKratesProve() is the proof generation calling function, and statement is the equity information.

[0080] Step 2042: Generate user rights and interests data based on the rights and interests certificate, rights and interests information, user key pair and user identification.

[0081] In the embodiment of the present invention, the user rights and interests data includes but is not limited to a rights and interests identification, a rights and interests proof, rights and interests information, a user key pair and a user identification.

[0082] Step 205: Upload the user rights data to the blockchain so that the blockchain can verify the user rights data through a smart contract.

[0083] Specifically, the communication interface between the trading platform and the blockchain is called to upload the user rights and interests data to the blockchain for storage.

[0084] In the embodiment of the present invention, the blockchain smart contract uses zero-knowledge proofs to verify the user's rights and interests data. Specifically, the smart contract receives the user's rights and interests data, obtains the user's public key publicKey, rights and interests proof and rights and interests information from the blockchain, and determines the validity of the user's rights and interests data through isValid = ZoKratesVerify (statement, proof, publicKey). If the user's rights and interests data is valid, the smart contract records the verification result and stores the user's rights and interests data on the blockchain; if the user's rights and interests data is invalid, the smart contract refuses to store the user's rights and interests data. Among them, isValid is the verification result of whether the user's rights and interests data is valid, ZoKratesVerify() is the calling function for verifying the validity, proof is the rights and interests proof, statement is the rights and interests information, and publicKey is the user's public key.

[0085] The present invention utilizes blockchain smart contract technology to ensure the privacy protection and security of user rights and interests data. User sensitive information does not need to be transmitted between different platforms, ensuring that data between consumption platforms are independent of each other, reducing the risk of leakage, and can enhance the anti-counterfeiting and authenticity verification of user rights and interests data, prevent forgery and abuse, and ensure the security of user privacy data and user rights and interests data.

[0086] Step 206: Obtain user transaction information through cross-platform user association relationships, where the user transaction information includes a user identifier.

[0087] In the embodiment of the present invention, the user transaction request is a consumption request initiated by the user through a transaction platform or an APP. Since the same user can be associated with each other on various transaction platforms and APPs, the background can obtain user transaction information for consumption requests initiated by the user on any transaction platform or APP.

[0088] In the embodiment of the present invention, the user identifier in the user transaction information can uniquely identify the user who initiates the consumption request.

[0089] Step 207: Call the platform interface to send a rights query request to the blockchain. The rights query request includes a user identifier so that the blockchain can query the rights data according to the user identifier.

[0090] In an embodiment of the present invention, the platform interface is a communication interface between a trading platform or an APP and a blockchain; the blockchain responds to a rights query request and queries the corresponding user rights data from the on-chain storage data according to the user identifier.

[0091] Step 208: Receive user rights and interests data returned by the blockchain.

[0092] In an embodiment of the present invention, if the blockchain queries the user's rights and interests data, the rights and interests identification, rights and interests proof, rights and interests information, user key pair and user identification in the user's rights and interests data are returned; if the blockchain does not query the user's rights and interests data, an empty set is returned.

[0093] Furthermore, if the user's rights and interests data is empty, a message indicating that no rights and interests are available is generated; the message indicating that no rights and interests are available is sent to the user end. The message indicating that no rights and interests are available indicates that the user does not have rights and interests data, and consumption deduction cannot be performed. The message indicating that no rights and interests are available is sent to the user end to inform the user that there is no available rights and interests data, and the current user transaction needs to be executed at the original price, and rights and interests cannot be redeemed and deducted.

[0094] Step 209: Verify the user rights and interests data according to the user transaction information. If the user rights and interests data verification passes, execute step 210; if the user rights and interests data verification fails, the process ends.

[0095] Specifically, according to the preset rights and interests usage rules, the user transaction information and the user rights and interests data are matched. If the match is successful, it is determined that the user rights and interests data verification has passed; if the match fails, it is determined that the user rights and interests data verification has failed.

[0096] In the embodiment of the present invention, the equity use rules can be pre-set according to the actual needs of the user transaction, and the embodiment of the present invention does not limit this. As an optional solution, the equity use rules include but are not limited to the equity use time, equity use type and equity available amount.

[0097] In the embodiment of the present invention, if both the user transaction information and the user equity data comply with the equity usage rules, and the types of the user transaction information and the user equity data match, it indicates that the user equity data can be used for the user transaction information, the user equity data verification is successful, and step 210 is continued; if at least one of the user transaction information and the user equity data does not comply with the equity usage rules, or the types of the user transaction information and the user equity data do not match, the user equity data verification fails, and the process ends.

[0098] Furthermore, if the user's rights and interests data verification fails, a no-matching rights and interests message is generated; the no-matching rights and interests message is sent to the user end. Among them, the no-matching rights and interests message indicates that the rights and interests data of the user cannot be used in the current transaction, does not comply with the rights and interests usage rules, and cannot be used for consumption deduction. The no-matching rights and interests message is sent to the user end to notify the user that the rights and interests data cannot be used, and the current user transaction must be executed at the original price, and the rights and interests cannot be redeemed and deducted.

[0099] Step 210: Perform cross-platform rights exchange based on user rights data to complete the user transaction.

[0100] In the embodiment of the present invention, step 210 specifically includes:

[0101] Step 2101: Perform cross-platform rights exchange according to user rights data, update user transaction information, and obtain updated exchange transaction information.

[0102] In an embodiment of the present invention, if the user benefit data is a coupon, the consumption amount in the user transaction information is deducted according to the preferential information of the coupon to obtain the consumption amount after deduction; based on the consumption amount after deduction and the transaction information, the updated redemption transaction information is generated.

[0103] For example: if the user's rights and interests data is a coupon purchased on consumption platform A, the user needs to make a purchase on consumption platform B; according to the preferential information of the coupon purchased on consumption platform A, the consumption amount in the user's transaction information on consumption platform B is deducted across platforms to obtain the consumption amount after deduction; based on the consumption amount after deduction and the transaction information, the updated redemption transaction information is generated, thereby realizing the automatic redemption of user's cross-platform rights and interests, the transaction is more real-time, and the speed of rights and interests redemption is increased, thereby improving transaction efficiency.

[0104] Step 2102: Send the exchange transaction information to the user terminal so that the user terminal can send a confirmation transaction instruction.

[0105] In the embodiment of the present invention, the exchange transaction information is sent to the user terminal so that the user can view the transaction information after using the equity data, and send a confirmation transaction instruction or a rejection transaction instruction through the user terminal.

[0106] Furthermore, if the user sends a transaction rejection instruction through the user terminal, it indicates that the user refuses to pay and the transaction is terminated.

[0107] Step 2103: In response to the confirmation transaction instruction, execute the user transaction according to the redemption transaction information.

[0108] In an embodiment of the present invention, if the user sends a confirmation transaction instruction through the user terminal, indicating that the user agrees to pay, the payment account bound to the user is deducted according to the consumption amount after deduction in the redemption transaction information, the user transaction is completed and the transaction result is returned.

[0109] Step 211: Call the platform interface to send a rights exchange message to the blockchain so that the blockchain can store the rights exchange message on the chain.

[0110] In an embodiment of the present invention, the platform interface is a communication interface between a trading platform or an APP and a blockchain; a rights exchange message is sent to the blockchain, and the rights exchange message includes but is not limited to a user identifier, user rights data, user transaction information, and exchange transaction information; the blockchain stores the rights exchange message on the blockchain, provides a review function for users, ensures that the data is not tampered with, and improves security.

[0111] The present invention provides an automated, intelligent, and seamless exchange process for the rights and interests data owned by users on different trading platforms. Users do not need additional intervention and manual operations, which greatly simplifies the user operation process and improves the user experience, thereby attracting more users to purchase rights and interests data and enhancing the competitiveness of the platform. The use of blockchain smart contract technology ensures the privacy protection and security of rights and interests data. User sensitive information does not need to be transmitted between different platforms, reducing the risk of leakage, and can enhance the anti-counterfeiting and authenticity verification of rights and interests data, preventing forgery and abuse.

[0112] It is worth noting that the acquisition, storage, use, and processing of data in the technical solution of this application are in compliance with the relevant provisions of laws and regulations. The user information in the embodiments of this application is obtained through legal and compliant channels, and the acquisition, storage, use, and processing of user information are authorized and agreed by the customer.
