Description

Technical Field

[0001] This invention belongs to the field of digital rights transfer technology, specifically relating to a method and system for the transferable trading of digital membership rights. Background Technology

[0002] Digital membership benefits refer to exclusive privileges, discounts, or services offered by businesses to registered members through digital platforms (such as apps, mini-programs, official websites, etc.), aiming to enhance user stickiness, promote consumption conversion, and achieve precise operation through data analysis.

[0003] In existing technologies, traditional centralized digital membership rights management systems suffer from trust dependence and efficiency bottlenecks. Existing systems typically rely on a central database of a single platform to issue, manage, and rescind rights. This architecture results in rights being strictly bound to user accounts and data being under the absolute control of the platform.

[0004] First, the transfer of rights and interests relies entirely on the platform's credit endorsement and system reliability, which poses risks such as data tampering, server downtime, or platform misconduct leading to overselling, resulting in a lack of a credible and neutral environment for both parties in the transaction.

[0005] Secondly, because the rights and interests systems of different platforms are not interconnected, "data silos" are formed, making it impossible for users to transfer or trade their idle rights and interests across platforms, resulting in a waste of resources;

[0006] Finally, the transfer of rights and interests often requires complex manual operations on the platform backend or cumbersome reconciliation between systems. The process is opaque, inefficient, and prone to disputes. At the same time, it is difficult to effectively prevent fraudulent activities such as "double consumption" because the status updates of centralized systems are delayed and can be manipulated. Summary of the Invention

[0007] To address the aforementioned problems in the existing technology, this invention provides a method and system for the transferable trading of digital membership rights. It aims to solve the technical problem that the transfer of rights in the existing technology relies entirely on the credit endorsement and system reliability of the platform, which poses risks of data tampering, server downtime, or platform misconduct leading to overselling and resulting in a lack of a trustworthy and neutral environment for both parties in the transaction.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a method for the transferable and tradable use of digital membership rights, comprising the following steps:

[0009] Step 1: Receive and store the digital membership rights information submitted by the user through a smart contract deployed on the blockchain network. The rights information includes at least the rights identifier, category, remaining value, and status.

[0010] Step 2: Receive a rights transfer transaction request from a user. This request must include at least the transaction amount range, the blockchain account address of the issuer, and the rights identifier.

[0011] Step 3: By calling the smart contract, the ownership of the rights is changed from the issuer's blockchain account address to the purchaser's blockchain account address, and a transaction record containing the transaction time, the addresses of both parties, and the transaction amount is generated on the blockchain;

[0012] Step 4: Complete the transfer of transaction amount through the settlement service based on the aforementioned transaction records.

[0013] Furthermore, the smart contract includes at least one of the following: a membership identity contract, a rights and interests data information contract, a membership rights and interests contract, and a membership transfer and transaction contract;

[0014] The membership identity contract is used to store the association between a member's blockchain account address and their platform identity identifier;

[0015] The rights data information contract is used to store the category, name, and description information of rights;

[0016] The membership rights contract is used to store specific rights instances held by members, including rights identifiers, remaining values, status, and the blockchain account address to which they belong;

[0017] The member transfer transaction contract is used to store the transaction hash, the addresses of both parties, the rights identifier, and the transaction amount for each transfer transaction.

[0018] Furthermore, prior to the transfer of rights, the method also includes:

[0019] Step 1: Verify whether the blockchain account address of the request initiator is bound to its platform identity identifier through the membership identity contract;

[0020] Step 2: Through the membership rights agreement, query whether the status corresponding to the rights identifier is tradable and whether the address to which it belongs is the address of the publisher.

[0021] Furthermore, in the settlement process, an independent equity stable value contract is used, which stores a fixed conversion ratio between different equity categories and an intermediate unit of measurement. The settlement service converts the transaction amount into actual fiat currency or digital currency based on this ratio and then transfers it.

[0022] Furthermore, the method receives transaction requests sent by the front-end application through a message queue service, and the back-end business logic service processes the request asynchronously by calling the corresponding smart contract.

[0023] A system for implementing the transferable trading of digital membership rights as described in any one of claims 1-5, comprising a user identity management module, a blockchain smart contract service module, a rights trading module, and a risk control module;

[0024] The user identity management module is used to maintain the mapping relationship between user platform identity information and blockchain account addresses;

[0025] The blockchain smart contract service module is used to deploy and invoke various smart contracts that process digital membership rights;

[0026] The rights and interests trading module is used to process user-submitted requests for rights and interests to be published, listed, viewed, and traded.

[0027] The risk control analysis module is used to perform real-time analysis of incoming transaction requests.

[0028] Furthermore, the user identity management module further includes a user platform identity information storage unit, a user on-chain identity information storage unit, and an identity association service unit;

[0029] The user platform identity information storage unit stores users' nicknames and avatars based on a relational database;

[0030] The user's on-chain identity information storage unit stores the user-generated blockchain account address and public key;

[0031] The identity association service unit is used to associate and store a user's platform identity identifier with their blockchain account address.

[0032] Furthermore, the equity trading module further includes a digital member purchase and on-chain unit, a digital member listing and circulation unit, a trading market display unit, and a circulation and transaction settlement unit;

[0033] The digital membership purchase on-chain unit is used to process the user's first purchase of rights with fiat currency, write the rights data into the membership rights contract and bind it to their blockchain account address;

[0034] The digital membership listing and circulation unit is used to receive requests from users to set a transaction amount range and change the status of the specified rights to be tradable.

[0035] The trading market display unit is used to query the blockchain and return a list of all rights and interests that are in a tradable state;

[0036] The transaction settlement unit is used to trigger the external payment interface to complete fund clearing after the blockchain transaction is confirmed.

[0037] Furthermore, the risk control analysis module is connected to a message queue to consume transaction flow data in real time, and its internal components include an anti-fraud monitoring unit and a transaction limit control unit.

[0038] The anti-fraud monitoring unit is configured with abnormal pattern detection rules based on user behavior sequences;

[0039] The transaction limit control unit is used to determine the threshold for transaction frequency and amount within a unit of time.

[0040] Furthermore, the system also includes a data analysis module, which periodically acquires on-chain transaction data through the API interface of the blockchain node and synchronizes it to a data warehouse for offline statistical analysis.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. In this invention, each digital membership right is transformed into an independent, uniquely identifiable digital asset object through a smart contract. The entire process of asset creation, ownership confirmation, trading, and settlement is completed within a continuous, atomic blockchain operation. This achieves immutability, real-time synchronization, and self-verification of ownership changes and transaction records. In traditional centralized systems, right trading relies on platform credit, which carries the risk of overselling and record tampering. This method, through the distributed ledger characteristics of blockchain, ensures that every transaction is visible and irreversible to all participants, completely resolving the trust issue between trading parties and constructing a trustworthy trading environment without third-party endorsement. Since the state of each right is uniformly managed on-chain by a smart contract, any attempt to transfer or use the same right multiple times will be rejected by the network, fundamentally eliminating the possibility of fraud and ensuring the asset security of the platform and users. The complex process that traditionally requires the collaboration of multiple systems is simplified to a single smart contract call. This achieves "transaction as settlement" and "transaction as delivery," avoiding reconciliation difficulties and disputes caused by data inconsistencies between systems, and significantly reducing operating costs and transaction friction.

[0043] 2. In this invention, the user's real identity information on the platform is securely stored in a centralized database, while the generated blockchain account address is linked to the platform identity in a controllable and verifiable manner through an "identity association service unit." Transactions are conducted using the blockchain address, but when supervision and auditing are required, the authorized party can trace back to the user's real identity on the platform through this mapping relationship. Users use blockchain addresses in daily transactions, protecting the privacy of their transaction behavior and habits and preventing the leakage of sensitive information. Simultaneously, this design meets the needs of financial supervision and platform governance. In the event of disputes or suspicious transactions, identity tracing can be completed legally and compliantly, achieving "anonymous controllable," rather than complete anonymity. Users do not need to repeatedly submit real-name information in every transaction, making the process smoother. Furthermore, even if a platform's database is leaked, attackers cannot directly associate the leaked information with the user's vast assets and transaction history on the blockchain, providing an additional layer of security. This model provides the technical possibility for users to use a single on-chain identity across different platforms, truly realizing the vision of "one identity, universally applicable," without requiring platforms to share sensitive user data.

[0044] 3. In this invention, the contract defines a fixed conversion ratio between different categories of rights and an intermediate unit of measurement. The pricing and settlement of all rights must be standardized and converted according to this contract, rather than allowing users to set prices arbitrarily. This standardized "value scale" measures diverse rights, making rights from different categories and platforms comparable and exchangeable. Users can easily exchange idle video membership rights for equivalent coffee vouchers or points, thereby revitalizing existing rights assets within the entire ecosystem and forming a highly liquid, unified market. This avoids lengthy negotiation processes between buyers and sellers due to differing perceptions of rights value. It provides a clear and universally accepted pricing benchmark, making transactions more efficient and direct, much like trading different stocks on a standard stock exchange. The official conversion ratio set by the smart contract effectively anchors the value of rights, preventing drastic price fluctuations or malicious speculation due to insufficient liquidity in the early stages of the market, thus providing a foundation for the healthy and stable development of the market.

[0045] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used in conjunction with embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings:

[0046] Figure 1 This is a flowchart of the present invention;

[0047] Figure 2 This is a schematic diagram of the system in this invention. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example:

[0050] Please see Figure 1 This embodiment provides the following technical solution: a method for the transferable trading of digital membership rights, comprising the following steps: Step 1: Receiving and storing digital membership rights information submitted by users through a smart contract deployed on a blockchain network, the rights information including at least rights identifier, category, remaining value, and status; Step 2: Receiving a rights transfer transaction request issued by a user, the request including at least the transaction amount range, the blockchain account address of the issuer, and the rights identifier; Step 3: Changing the ownership of the rights from the blockchain account address of the issuer to the blockchain account address of the purchaser by calling the smart contract, and generating a transfer transaction record on the blockchain including the transaction time, the addresses of both parties, and the transaction amount; Step 4: Completing the transfer of the transaction amount according to the transfer transaction record through a settlement service.

[0051] Specifically, the process includes the following steps: Receiving and storing user-submitted digital membership rights information via smart contracts deployed on the blockchain network. This rights information includes at least the rights identifier, category, remaining value, sharer information, redemption information, creation time, and data status. Receiving rights transfer transaction requests from users through the front-end application. These requests include at least the transaction amount range, the publisher's blockchain account address, the rights identifier, and the publication time. Executing ownership change logic by calling the smart contract, transferring ownership of the rights instance from the publisher's blockchain account address to the buyer's blockchain account address, and generating an immutable transfer transaction record on the blockchain containing a unique transaction identifier, transfer transaction time, transaction status, publisher ID, buyer ID, purchase transaction time, and transaction amount. Finally, through the settlement service, based on the transaction amount determined in the transfer transaction record, calling an external payment interface to complete the transfer and settlement of funds between the two parties.

[0052] It has built a decentralized and highly trustworthy digital rights trading environment and significantly improved trading efficiency. This advantage is achieved through a series of technical features based on blockchain smart contracts, such as storing rights information on the chain, processing transfer requests, completing rights confirmation and transfer records, and executing transaction settlement.

[0053] The smart contract includes at least one of the following: a membership identity contract, a rights data information contract, a membership rights contract, and a membership transfer transaction contract. The membership identity contract stores the association between a member's blockchain account address and their platform identity identifier. The rights data information contract stores the category, name, and description of rights. The membership rights contract stores specific rights instances held by a member, including rights identifiers, remaining value, status, and their associated blockchain account addresses. The membership transfer transaction contract stores the transaction hash, addresses of both parties, rights identifiers, and transaction amount for each transfer transaction. Before rights transfer, the method further includes: Step 1: Verifying, through the membership identity contract, whether the request initiator's blockchain account address is bound to their platform identity identifier; Step 2: Querying, through the membership rights contract, whether the status corresponding to the rights identifier is tradable and whether its associated address is the publisher's address.

[0054] Specifically, the smart contract includes a custodian service contract and multiple business contracts. The business contracts specifically include: a member identity contract, used to store a member's nickname, avatar, identity status, identity number, on-chain ID, and associated digital member asset information; a rights data information contract, used to store basic rights data information, including rights ID, name, logo image, category, rights information description, ecosystem service, creation time, on-chain time, parameters, and data status; and a member rights contract, used to store information on specific rights instances held by a member, including ID, logo image, name, category, remaining value, sharer information, redemption information, and creation details. Time and data status; Member transfer transaction contract, used to store the core information of each transfer transaction, including transaction ID, transfer transaction time, transaction status, publisher ID, publication time, buyer ID, purchase transaction time and transaction amount; Before executing the rights transfer, the method also includes the following verification steps: By calling the member identity contract, verify whether the blockchain account address of the request initiator has been effectively bound and authenticated through its platform identity identifier; By querying the member rights contract, verify whether the current data status corresponding to the target rights identifier is in a tradable state, and verify whether the blockchain account address to which the rights currently belong is consistent with the address of the request publication;

[0055] This ensures the authenticity of the transaction parties and the validity of the rights and interests, thus providing a technical foundation for preventing fraudulent transactions. This advantage is achieved by using membership identity contracts to verify user identity relationships and by utilizing the technical features of membership rights contracts to query the status and ownership of rights and interests.

[0056] In the settlement process, an independent equity stable value contract is used. This contract stores a fixed conversion ratio between different equity classes and an intermediate unit of measurement. The settlement service converts the transaction amount into actual fiat currency or digital currency based on this ratio and then transfers it.

[0057] Specifically, in the settlement process, an independent equity stable value contract is referenced; this contract stores fixed conversion ratios between different equity classes and an intermediate unit of measurement, as well as their effective dates; the settlement service converts the transaction amount from the intermediate unit of measurement into actual fiat currency or digital currency based on the currently effective conversion ratio defined in the contract before transferring it.

[0058] It provides a unified standard for measuring the value of diversified digital rights and interests and a stable medium of exchange, reducing the bargaining costs and cognitive friction between the two parties in the transaction. This advantage is achieved by introducing an independent rights and interests stable value contract and using its stored fixed conversion ratio value for settlement.

[0059] The method receives transaction requests sent by the front-end application through a message queue service, and the back-end business logic service processes the request asynchronously by calling the corresponding smart contract.

[0060] Specifically, the system asynchronously receives high-concurrency transaction requests sent by the front-end application through a message queue service, and the back-end business logic service consumes the messages in the queue, and then calls the corresponding smart contract to complete the on-chain operation, thereby dealing with high-concurrency processing in the flash sale scenario.

[0061] This improves the system's throughput and stability in handling high-concurrency transaction requests, avoiding system blocking caused by synchronous request processing. This advantage is achieved by using the technology of asynchronously receiving and processing transaction requests through a message queue service.

[0062] A system for enabling the transferable trading of digital membership rights as described in any of claims 1-5 includes a user identity management module, a blockchain smart contract service module, a rights trading module, and a risk control module; the user identity management module is used to maintain the mapping relationship between user platform identity information and blockchain account addresses; the blockchain smart contract service module is used to deploy and call various smart contracts for processing digital membership rights; the rights trading module is used to process user-submitted rights publishing, listing, browsing, and trading requests; and the risk control analysis module is used to perform real-time analysis of the incoming transaction requests.

[0063] Specifically, the system adopts a microservice architecture, mainly divided into a front-end presentation layer, a business logic layer, a smart contract service layer, a data access layer, and an external interface layer. Its core modules include: a user identity management module, used to maintain user platform identity information, on-chain identity information, and the relationship between the two; a blockchain smart contract service module, used to deploy, call, and configure various business logic smart contracts for handling digital member rights; a rights trading module, used to process user-submitted rights publishing, listing, browsing, interaction, and transaction matching requests; and a risk control analysis module, used to perform real-time anti-fraud monitoring and behavior analysis on the incoming transaction requests.

[0064] A highly cohesive, loosely coupled, easily scalable and maintainable digital equity trading system was constructed. This advantage was achieved by explicitly adopting a microservice architecture and defining the technical characteristics of core modules, including user identity management, smart contract services, equity trading, and risk control analysis.

[0065] The user identity management module further includes a user platform identity information storage unit, a user on-chain identity information storage unit, and an identity association service unit. The user platform identity information storage unit stores the user's nickname and avatar based on a relational database. The user on-chain identity information storage unit stores the user's generated blockchain account address and public key. The identity association service unit is used to associate and store the user's platform identity identifier with its blockchain account address.

[0066] Specifically, the user identity management module further includes: a user platform identity information storage unit, which stores basic information such as user ID, nickname, real identity information, avatar, gender, and age based on a relational database; a user on-chain identity information storage unit, which stores blockchain account information created by the user, including the blockchain account address, signature key, and blockchain category; and an identity association service unit, which is used to associate and map and store the user's platform identity identifier with its blockchain account address.

[0067] It achieves an effective balance between user identity protection and compliance regulation; this advantage is realized through the technical features of the collaborative operation of the user platform identity information storage unit, the user on-chain identity information storage unit, and the identity association service unit in the user identity management module.

[0068] The rights and interests trading module further includes a digital member purchase and on-chain unit, a digital member listing and circulation unit, a trading market display unit, and a circulation and transaction settlement unit. The digital member purchase and on-chain unit is used to process the rights and interests data after a user purchases rights and interests for the first time with fiat currency, writes the rights and interests data into the member rights and interests contract, and binds it to the user's blockchain account address. The digital member listing and circulation unit is used to receive requests from users to set a transaction amount range and change the status of the specified rights and interests to be tradable. The trading market display unit is used to query the blockchain and return a list of all rights and interests with a status of tradable. The circulation and transaction settlement unit is used to trigger an external payment interface to complete fund settlement after the blockchain transaction is confirmed.

[0069] Specifically, the rights and interests trading module further includes: a digital member purchase and on-chain unit, used to process users' first purchase of digital member rights with fiat currency, create rights and interests data information, call smart contracts to put it on the blockchain, and bind it to their blockchain account address; a digital member listing and circulation unit, used to receive users' requests to set transaction ranges for their unfrozen valid digital members and publish listing requests to the trading market; a digital member trading market unit, used to query from the blockchain and display a list of all valid digital members with a tradable status to the front end, and provide identity verification and interactive trading interfaces; and a circulation and transaction settlement unit, used to trigger external payment interfaces to complete fund settlement and update the status of relevant rights and interests after blockchain transaction confirmation.

[0070] It provides complete transaction functions covering the entire lifecycle of digital rights, forming a closed-loop business ecosystem. This advantage is achieved through the technical features of the sequential collaboration of the digital member purchase on-chain unit, the listing and circulation unit, the transaction market display unit, and the circulation transaction settlement unit in the rights transaction module.

[0071] The risk control analysis module is connected to the message queue and consumes transaction flow data in real time. It includes an anti-fraud monitoring unit and a transaction limit control unit. The anti-fraud monitoring unit is configured with abnormal pattern detection rules based on user behavior sequences. The transaction limit control unit is used to determine thresholds for transaction frequency and amount within a unit of time.

[0072] Specifically, the risk control analysis module is connected to the message queue and consumes transaction flow data in real time. It includes: an anti-fraud monitoring unit, which is configured with abnormal pattern detection rules based on user operation behavior sequences to identify malicious transaction behavior; and a transaction limit control unit, which is used to judge the threshold and circuit breaker control of the transaction frequency and cumulative transaction amount of a specific user account within a unit of time.

[0073] It can identify and proactively intervene in transaction risks in real time, ensuring the financial security and operational stability of the trading platform. This advantage is achieved through the technical features of configuring abnormal pattern detection rules in the anti-fraud monitoring unit of the risk control analysis module and threshold judgment by the transaction limit control unit.

[0074] The system also includes a data analysis module, which periodically acquires on-chain transaction data through the API interface of the blockchain node and synchronizes it to a data warehouse for offline statistical analysis.

[0075] Specifically, the system also includes a data analysis module, which periodically acquires on-chain transaction data and user behavior data through the API interface of the blockchain node and synchronizes them to a data warehouse for off-chain transaction data statistics, user behavior analysis and generation of operation reports.

[0076] It provides reliable data support for business decision-making and operational optimization, and realizes the combination of transparent on-chain data and in-depth off-chain analysis. This advantage is achieved through the technical feature that the data analysis module periodically obtains on-chain data through the blockchain API interface and synchronizes it to the data warehouse.

[0077] The working principle of this invention is as follows: Users submit digital membership rights information or transaction requests through the front-end application. After receiving the request, the business logic layer calls the user identity management module to verify the correlation between the user's platform identity and on-chain identity and confirm the permissions. Subsequently, the blockchain smart contract service module is triggered, and the corresponding smart contract is called to put the rights information on the chain to complete the digital confirmation of rights or query its current status and ownership.

[0078] For transfer and transaction requests, the system processes them through the equity trading module. First, the digital member puts the equity on the transfer unit to change the equity status to tradable and sets the price. The trading market unit displays the list of tradable equity to potential buyers. Once the transaction is completed, the smart contract is called again to execute the on-chain change of ownership from the seller to the buyer and generate an immutable transaction record in the member's transfer and transaction contract.

[0079] Meanwhile, the risk control analysis module monitors the transaction data stream in the message queue in real time, and uses anti-fraud rules and limit control strategies to scan and intervene in transaction behavior to ensure security. Finally, the transaction settlement unit completes fund clearing according to the preset conversion ratio in the equity stable value contract, and completes fund transfer by calling the payment service through the external interface. Throughout the process, the message notification module sends key operation prompts to users, while the data analysis module asynchronously synchronizes on-chain data to the data warehouse for subsequent analysis.

[0080] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
