Description

Technical Field

[0001] The present application relates to the field of information security and can be used in the financial field. Specifically, it is a consumption voucher processing method and device based on blockchain. Background Art

[0002] In the context of e-commerce, in order to stabilize the economic situation, government agencies, financial institutions and third-party payment platforms often issue electronic consumer vouchers to stimulate consumption. The traditional electronic consumer voucher circulation model has the following bottlenecks, which leads to poor results in actual use, specifically in the following aspects:

[0003] (1) There are many restrictions and high thresholds for redeeming electronic consumer vouchers.

[0004] (2) Electronic consumer coupons are too scattered and cannot be shared and used cumulatively, which reduces the circulation rate of consumer coupons and users' consumption interest.

[0005] (3) The issuance of electronic consumer vouchers is not transparent and lacks credibility. Users are unable to promptly verify whether the consumer vouchers have been issued as agreed, and there is a lack of trust and stickiness.

[0006] (4) Under the centralized architecture, the electronic consumer voucher operation platform is extremely complex.

[0007] (5) Electronic consumption voucher information is easily attacked by hackers and has low security.

[0008] (6) The electronic consumer voucher clearing rules between government agencies and businesses are complex, and an effective consumer voucher ecosystem has not been formed.

[0009] At present, blockchain technology, as the core technology that triggers the subversive revolutionary wave, can solve the above problems well, because it can change the conventional transaction process and record keeping method, thereby greatly reducing transaction costs and improving transaction efficiency. At the same time, blockchain technology has the characteristics of transparency, openness and non-tamperability, and can record the entire process of electronic consumer coupons from issuance to consumption, ensuring the traceability of issuance and consumption. At present, there is no method to realize the circulation of consumer coupons using blockchain technology. Summary of the invention

[0062] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] The blockchain-based consumption voucher processing method and device described in this application relate to the field of information security and can be used in the financial field as well as in any field other than the financial field. This application does not limit the application field of the blockchain-based consumption voucher processing method and device.

[0064] See also Figure 1 In order to realize the circulation of electronic consumer vouchers by using blockchain technology, this application provides a blockchain-based consumer voucher processing method, including:

[0065] S101: Determine the best consumption voucher main chain according to the consumption operation instruction received from the consumption voucher management terminal and the load balancing rule of the consumption voucher management terminal;

[0066] S102: Allocate the consumption operation instruction to the consumption voucher shard chain corresponding to the optimal consumption voucher main chain, so that the consumption voucher shard chain executes the consumption operation instruction;

[0067] S103: Perform on-chain data synchronization and off-chain data synchronization on the execution results agreed upon on the consumption voucher shard chain.

[0068] It is understandable that the blockchain-based consumption voucher processing method proposed in this application can be applied to a multi-scenario management system based on blockchain consumption vouchers. The system uses blockchain technology to identify the authenticity of transaction commitments, can grasp the risk control standards, and provide protection for the consumption voucher certificates generated on the blockchain, so that consumers can trade and transfer with confidence. Based on blockchain technology, each participant can obtain a complete consumption track of consumption vouchers in the system. Through effective statistical analysis and data mining, it can help government agencies or businesses understand consumers' consumption patterns, thereby improving promotions to provide personalized and customized discount packages, while maintaining existing consumers while discovering potential target consumers.

[0069] Based on the consensus mechanism of blockchain technology, the issuance, circulation and use of consumption coupons do not require a central agency, which can not only prevent fraud, but also provide more convenient, autonomous, efficient and low-cost services for government agencies or businesses.

[0070] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0071] See also Figure 8 The design architecture diagram of the multi-scenario management system based on blockchain consumption vouchers includes three parts: the underlying control system, core components and consumption voucher ecology.

[0072] (1) The underlying management and control system includes core modules such as distributed database, publishing platform, data management and control platform and hyperlink service.

[0073] ① A distributed database is a decentralized database. A distributed database consists of a set of data distributed on different computers in a computer network. Each node in the network has independent processing capabilities and can execute local applications. At the same time, each node can also execute global applications through the network communication subsystem. The basic characteristics of a distributed database include physical distribution, logical integrity, and site autonomy. Other characteristics can also be derived from these three basic characteristics, including data distribution transparency, a mechanism for reaching consensus according to established protocols, appropriate data redundancy, and distribution of transaction management. The distributed database stores encrypted ledgers and transaction events and other data. It has permission management and encryption and decryption algorithm modules, which can realize back-end access control of the underlying data.

[0074] ②The publishing platform is a platform for registering information related to consumer vouchers and automatically generating hyperlinks. The platform can register consumer voucher marketing information (including [scope of use], [consumer voucher category], [time limit], [user use agreement]), and can also submit automatic calculations of [total cost of consumer vouchers] and [number of promoters], and generate hyperlinks. The hyperlinks can be downloaded, exported, and shared on multiple consumer voucher management terminals (also known as channels).

[0075] ③The data management and control platform can provide integrated, self-service data management services and a unified data access interface, integrate the high-value-added data generated in the hyperlink sharing process of all parties, and provide data analysis, data management, data call, etc., to guide government agencies or businesses to optimize consumer vouchers and make investment decisions.

[0076] ④Hyperchain services can provide participants with different channels (such as major banks, government agencies, merchants and enterprises, and third-party payment platforms, etc.) to obtain consumer coupons, realize the consumption of consumer coupons during the sharing and dissemination process on the chain, and continuously and rapidly fission in the multi-scenario application of the blockchain to achieve the marketing conversion between consumer coupons and commodities.

[0077] (2) Core components include application programming interface, software development kit, consumer voucher issuance, consumer voucher distribution, consumer voucher redemption, voucher collection status, account replenishment payment, remittance settlement and consumer voucher on-chain system.

[0078] ① Application programming interface, software development kit, consumption voucher release, consumption voucher issuance, consumption voucher redemption, collection status, account replenishment payment and remittance settlement are lightweight, highly secure and highly available components for blockchain node data processing. They provide a calling interface for upper-level applications and forward them to the underlying management and control system for processing. They are pluggable and flexibly assembled component components, which improve the efficiency of secondary development and reduce development costs. More functions and solution sub-components will be provided in the future based on business and scenario requirements.

[0079] ②The consumption voucher on-chain system is a consumption voucher management system based on blockchain. Since blockchain is a "decentralized" distributed ledger, the consumption voucher on-chain system is based on blockchain access to unified consumption vouchers. Each government agency or merchant enterprise that joins can stimulate user consumption according to its own consumption voucher issuance rules. Consumption vouchers can be issued on the chain or a token can be issued on the chain for each type of consumption voucher connected. The exchange between consumption vouchers can be realized through smart contracts to achieve point-to-point transactions. In this way, user consumption vouchers can be uniformly accumulated and used by any party in the consumption voucher alliance, expanding the "export" of consumption vouchers and enjoying diversified services. As nodes in the blockchain network, everyone can supervise each other, and transactions are transparent and traceable, which enhances the credibility of consumption vouchers.

[0080] (3) The consumer voucher ecosystem includes consumer voucher alliances and consumer voucher marketing.

[0081] ① The Consumer Voucher Alliance supports the access mechanism of the alliance chain, adopts a multi-organization alliance and regional autonomy approach, and provides functions such as multi-chain isolation and permission management of multiple organizations and multiple accounts in the alliance.

[0082] ②Consumer voucher marketing refers to the promotion, exchange, sharing and redemption of consumer vouchers. Through the marketing plan of consumer vouchers, the conversion rate between consumer vouchers and commodities can be improved, the traffic from different channels can be achieved, the consumption rate of consumers can be increased and the enjoyment of diversified services can be achieved.

[0083] From the above description, it can be seen that the blockchain-based consumption voucher processing method provided in this application can use blockchain technology to realize the circulation of electronic consumption vouchers. At the same time, due to the transparent, open and tamper-proof nature of blockchain technology, it can record the entire process of electronic consumption vouchers from issuance to consumption, ensuring the traceability of issuance and consumption, greatly improving the security of e-commerce operations, improving the circulation efficiency of electronic consumption vouchers, and improving customers' consumption experience, and thus can guide government agencies or merchants to optimize and make decisions on the issuance of electronic consumption vouchers.

[0084] See also Figure 2 , according to the consumption operation instructions received from the consumption voucher management end and the load balancing rules of the consumption voucher management end, the best consumption voucher main chain is determined, including:

[0085] S201: Determine the weight of each consumption voucher main chain according to the load balancing rule;

[0086] S202: Determine the best consumption voucher main chain according to the weight.

[0087] It is understandable that the multi-scenario management system based on blockchain consumption vouchers can be connected to different consumption voucher management terminals (also known as channels), such as major banks, government agencies, third-party payment platforms, etc. Channels can initiate operation instructions for consumption voucher-related transactions. These operation instructions include consumption voucher generation operations, consumption voucher issuance operations, consumption voucher sharing operations, consumption voucher collection operations, consumption voucher consumption operations, and consumption voucher cancellation operations.

[0088] For the above operation instructions, the best consumption voucher main chain can be determined according to the consumption operation instructions received from the consumption voucher management end and the load balancing rules of the consumption voucher management end.

[0089] Specifically, DNS load balancing can be performed based on the user domain name, and the corresponding main chain server can be requested to perform business transaction operations. The above DNS load balancing process can effectively solve the problems of transaction network congestion and server downtime. When encountering network congestion or server unresponsiveness, the best consumption voucher main chain can be selected according to the DNS load balancing rules, greatly improving the performance of the blockchain.

[0090] In addition, the weight of each consumer voucher main chain can be determined according to the load balancing rules, for example, a relatively idle server has a larger weight, a relatively busy server has a smaller weight, etc., but the present application is not limited thereto. After determining the weight of each server, the best consumer voucher main chain can be determined according to the weight, for example, the main chain corresponding to the server with the largest weight can be selected as the best consumer voucher main chain.

[0091] In one embodiment, the above-mentioned business transaction operations, in the order in which the business occurs, specifically include: consumption voucher generation, consumption voucher issuance, consumption voucher sharing, consumption voucher collection, consumption voucher consumption, consumption voucher cancellation and off-chain and on-chain data synchronization, etc.

[0092] The DNS load balancing method can be as follows:

[0093] In the first step, the user requests domain name resolution from the DNS server;

[0094] In the second step, the DNS server returns the corresponding IP address xxx.xxx.xxx to the user

[0095] In the third step, the user uses the IP address xxx.xxx.xxx to access the server xxx.xxx.xxx corresponding to the server cluster.

[0096] In the fourth step, the server xxx.xxx.xxx selects the best consumer voucher main chain to perform the business transaction operation requested by the user based on the weight usage of its corresponding consumer voucher main chain cluster.

[0097] From the above description, it can be seen that the blockchain-based consumption voucher processing method provided by this application can determine the optimal consumption voucher main chain based on the consumption operation instructions received from the consumption voucher management end and the load balancing rules of the consumption voucher management end.

[0098] In one embodiment, the steps of executing the consumption operation instruction by the consumption voucher shard chain include:

[0099] The shard chain consumption voucher generation operation is performed according to the pre-set name, denomination, type, validity period, scope of use and usage platform of the consumption voucher.

[0100] It is understandable that after the load balancing is completed, the best consumer voucher main chain can receive operation instructions from various channels, so the operation instructions such as consumer voucher generation, consumer voucher issuance, consumer voucher sharing, consumer voucher collection, consumer voucher consumption, consumer voucher cancellation and data synchronization can be assigned to the consumer voucher shard chain corresponding to the best consumer voucher main chain. Among them, the consumer voucher shard chain also includes consumer voucher generation, consumer voucher issuance, consumer voucher sharing, consumer voucher collection, consumer voucher consumption, consumer voucher cancellation and data synchronization. Instructions corresponding to consumer voucher transactions can be carried out in the consumer voucher shard chain. This sharding process allows different shards to store different state data. Each shard and its nodes only maintain and manage their own shard data, rather than the complete world state data. This can reduce redundant storage of states and improve the scalability of the blockchain system in storage.

[0101] When the corresponding consumer voucher shard chain is processed, the consensus block shards can be assembled into a complete block and submitted to the consumer voucher main chain blockchain system. Among them, the consumer voucher shard chain is responsible for accounting, and the consumer voucher main chain is responsible for confirmation, which can effectively avoid the double-spending problem.

[0102] Among them, the shard chain consumption voucher generation means that the shard chain only handles the consumption voucher generation, that is, what kind of consumption voucher needs to be created, and the basic attributes of the consumption voucher such as name, denomination, type, validity period, scope of use, and usage platform need to be set.

[0103] In one embodiment, the step of executing the consumption operation instruction by the consumption voucher shard chain further includes:

[0104] The shard chain consumption voucher issuance operation is performed on the generated consumption voucher according to the preset usage time, usage method, denomination, activity name, issuance object, issuance form, issuance data and collection restriction of the consumption voucher.

[0105] It can be understood that the shard chain consumption voucher release means that the shard chain only handles the consumption voucher release, that is, when, in what way, to whom, and the denomination of each consumption voucher, etc. When releasing consumption vouchers, at least several conditions must be set: activity name, release object, release form, release data, and collection restrictions, etc.

[0106] In one embodiment, the step of executing the consumption operation instruction by the consumption voucher shard chain further includes:

[0107] The released consumption vouchers are executed in sequence: sharing operation, receiving operation, consumption operation and cancellation operation of shard chain consumption vouchers.

[0108] It is understandable that the shard chain voucher sharing means that the shard chain only handles voucher sharing, that is, users share vouchers among users through third-party payment platforms. At the same time, in order to attract new users, promote activation, repurchase, and stimulate consumption, operators can actively push vouchers to users and notify them to reach users.

[0109] Shard chain consumption voucher collection means that the shard chain only handles consumption voucher collection. After consumers obtain consumption vouchers through a third-party payment platform, they can directly find the consumption vouchers in the card wallet of the corresponding platform.

[0110] Shard chain voucher consumption means that the shard chain only processes voucher consumption. After consumption, when consumers use the platform to pay, when they reach the voucher usage threshold, they can directly use the voucher to deduct the corresponding amount when paying.

[0111] The invalidation of consumption vouchers on the shard chain means that the shard chain only handles the invalidation of consumption vouchers, which refers to operations such as the expiration and overdue invalidation of consumption vouchers, or operations such as the consumption voucher subject actively invalidating consumption vouchers within the legal and compliant scope.

[0112] Shard chain data synchronization means that the shard chain only processes off-chain and on-chain synchronization data, that is, whether it is actively initiating the update of consumption voucher data on the channel platform, such as the merchant actively invalidating consumption vouchers; or updating consumption voucher data in the blockchain consumption voucher multi-scenario management system, such as the automatic invalidation of consumption vouchers upon expiration. Consumption voucher data is kept in timely synchronization on the chain and off-chain.

[0113] From the above description, it can be seen that in the blockchain-based consumption voucher processing method provided in this application, the consumption voucher shard chain can execute consumption operation instructions.

[0114] See also Figure 3 , the consensus-based execution results on the consumption voucher shard chain will be synchronized on-chain and off-chain, including:

[0115] S301: Upload the key information of the consumer voucher corresponding to the consensus-completed consumer voucher shard chain to the consumer voucher main chain; the key information includes the consumer voucher ID, issuing entity, entity description, consumer voucher type, consumer voucher amount, consumer voucher start validity period, consumer voucher end validity period, available goods, consumer name, consumer contact number, creator, creation time, off-chain slice ID and other information;

[0116] S302: Confirm the key information of the consumer voucher on the consumer voucher main chain corresponding to the consumer voucher shard chain by voting by nodes and broadcast the confirmed key information of the consumer voucher to other consumer voucher main chains to complete the on-chain data synchronization;

[0117] It is understandable that in order to synchronize data, the key information of the consumption vouchers on all shard chains needs to be included in the main chain, and then the main chain confirms the block information on the shard chain. In addition to the key information of the consumption vouchers in the shard chain block and the necessary information of the main chain itself, the main chain does not include any other data. Among them, the key information of the consumption voucher includes: consumption voucher ID, issuing entity, entity description, consumption voucher type, consumption voucher amount, consumption voucher start validity period, consumption voucher end validity period, available goods, consumer name, consumer contact number, creator, creation time, off-chain slice ID, etc. When the main chain confirms that the ledger data of the shard chain is fine, it broadcasts and synchronizes these data to other consumption voucher main chains to ensure the consistency of the blockchain storage data ledger and complete the on-chain data synchronization.

[0118] S303: The confirmed key information of the consumption voucher is transmitted to the consumption voucher management terminal to complete the off-chain data synchronization.

[0119] It is understandable that data synchronization refers to the bidirectional synchronization of on-chain and off-chain systems. When there are changes in on-chain and off-chain data, timely synchronization and update are required. For example, the ledger data of the batch-voided consumption coupons in this blockchain system will be synchronized to the database of the corresponding channel in a timely manner, that is, off-chain data synchronization. Similarly, if there are operations to change data in different channels, the associated on-chain consumption coupon data will also be synchronized in a timely manner, that is, on-chain data synchronization. In order to ensure the consistency of on-chain block data and off-chain data, we conduct consistency verification between the latest status data of the blockchain and the off-chain data through regular queries.

[0120] In one embodiment, the NSQ message push server can be used as the middleware for on-chain and off-chain data coordination to synchronize data in an asynchronous manner. This can avoid the problem of waiting for the off-chain database to be updated when executing transactions, effectively reducing the performance impact of data synchronization on the blockchain system.

[0121] NSQ is an open source distributed real-time messaging platform based on the Go language. It can be used for real-time messaging services in large-scale systems. It can process hundreds of millions of messages every day and has a distributed and decentralized topology. This structure has the characteristics of no single point of failure, fault tolerance, high availability, and the ability to maintain reliable message delivery. At the same time, NSQ is easy to configure and deploy, supports a variety of messaging protocols, and its design goal is to provide a powerful infrastructure for decentralized services running in a distributed environment.

[0122] In one embodiment, Fig. 9 This is a schematic diagram of the business application scenario of the blockchain-based consumer voucher multi-scenario management system. By building a consumer voucher main chain based on the blockchain-based consumer voucher multi-scenario management system and multiple side chains such as government agencies or merchant enterprise consumer vouchers, a one-main-multiple-side blockchain collaborative system is constructed, which allows consumer vouchers to circulate on various side chains through the main chain, achieving the purpose of information interaction and value transfer.

[0123] Users can obtain consumer coupons through third-party payment platforms, major banks, government agencies, merchants and enterprises, and at the same time, government agencies or merchants can also use the wide coverage of these channels to distribute consumer coupons. In this way, consumer coupons can be quickly distributed to specific groups of people in specific areas over a large range, increasing the reach of consumer coupons at the consumer end.

[0124] The use of blockchain to record the issuance of consumer vouchers and government mutual aid subsidies can ensure the traceability of consumer vouchers. In addition, blockchain can achieve decentralized management. By cooperating with various channels, a blockchain consumer voucher alliance ecosystem can be built to jointly build consumer voucher scenarios, providing more comprehensive services for issuing institutions and regulators, including but not limited to the full view management of consumer voucher issuance, registration, use, consumption, subsidies, remittance settlement and other information in various channels.

[0125] Fig.10 This is a business operation flow chart of the blockchain-based consumer voucher multi-scenario management system. Each government agency or business enterprise that joins the alliance can access the blockchain platform in a unified manner according to its own consumer voucher rules. Its consumer vouchers are generated, released and promoted on the chain. At the same time, it provides data analysis, data management and data call for government agencies or business enterprises, thereby guiding government agencies or business enterprises to optimize and accurately distribute consumer vouchers. At the same time, users can obtain consumer vouchers through different channels, and users can forward or share consumer voucher related information. The exchange of user consumer vouchers can be realized through smart contracts to achieve point-to-point transactions, and the evidence records of the entire process from the issuance of consumer vouchers to consumption can be traced.

[0126] Fig.11The figure is a schematic diagram of a blockchain node based on a blockchain consumption voucher management system, which includes N main chain nodes, where N is a positive integer. The above N main chain nodes include N shard chain nodes. Shard chain transactions are allocated according to specific attributes and operation instructions; different shard chains store different state data, and each shard and node only maintains and manages its own shard data, rather than the complete world state data. This can reduce redundant state storage and improve the storage scalability of the blockchain system. Finally, different shard chains complete consensus internally, and then the consensus block shards are aggregated into complete blocks and submitted to the main chain system.

[0127] Fig.12 Based on the blockchain consumption voucher multi-scenario management system transaction processing and ledger diagram, by introducing sharding consensus technology, DNS load balancing and data synchronization technology, a blockchain consumption voucher multi-scenario management system can be built that supports N channels to access and use N main chains at the same time, and each main chain corresponds to N shard chains. This system solves the problems of blockchain transaction processing efficiency and massive data storage, improves the performance of blockchain, and expands business application scenarios.

[0128] Based on the same inventive concept, the embodiments of the present application also provide a blockchain-based consumer voucher processing device, which can be used to implement the method described in the above embodiments, as described in the following embodiments. Since the principle of solving the problem by the blockchain-based consumer voucher processing device is similar to the blockchain-based consumer voucher processing method, the implementation of the blockchain-based consumer voucher processing device can refer to the implementation of the method based on software performance benchmark determination, and the repetitions will not be repeated. As used below, the terms "unit" or "module" can be a combination of software and / or hardware that implements predetermined functions.

The communication module (transmitter / receiver) 9110 is coupled to the central processor 9100 to provide input signals and receive output signals, which may be the same as the case of a conventional mobile communication terminal.

[0165] Based on different communication technologies, multiple communication modules 9110 may be provided in the same electronic device, such as a cellular network module, a Bluetooth module and / or a wireless LAN module. The communication module (transmitter / receiver) 9110 is also coupled to a speaker 9131 and a microphone 9132 via an audio processor 9130 to provide an audio output via the speaker 9131 and receive an audio input from the microphone 9132, thereby realizing a common telecommunication function.
