[0068] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0069] A blockchain is a carrier and organizational method for running blockchain technology. Blockchain technology (BT) is also known as distributed ledger technology, which is an Internet database technology characterized by decentralization, openness, and transparency, allowing everyone to participate in database records. Blockchain technology is a distributed infrastructure and computing method that uses a block-chain data structure to verify and store data, uses a distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data.

[0070] For ease of understanding, the blockchain and its related concepts will be elaborated below:

[0071] Blockchain: A blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithms. It is mainly used to organize data in chronological order, encrypt it into a ledger, making it impossible to be tampered with or forged, while also enabling data verification, storage, and update. Essentially, a blockchain is a decentralized database, and each node in this database stores an identical blockchain. The blockchain network can distinguish nodes into consensus nodes and business nodes, where the consensus nodes are responsible for the consensus across the entire blockchain network. For the process of transaction data being written into the ledger in the blockchain network, it can be as follows: The resource client sends transaction data to the business node, and then this transaction data is passed among business nodes in the blockchain network in a relay manner until the consensus node receives the transaction data. The consensus node then packs this transaction data into a block, conducts consensus with other consensus nodes, and after the consensus is passed, writes the block carrying this transaction data into the ledger.

[0072] Block: A block is a data packet that carries transaction data (i.e., transaction operations) on the blockchain network. It is a data structure marked with a timestamp and the hash value of the previous block. Blocks are verified by the network's consensus mechanism to determine the transactions within the block.

[0073] Hash value: Also known as information fingerprint or fingerprint, a hash value is generated by converting input data of any length into a cipher through a hash algorithm and performing a fixed output. It is impossible to retrieve the original input data by decrypting the hash value, and it is a one-way encryption function. In a blockchain, each block (except the initial block) contains the hash value of the previous block, and the previous block is called the parent block of the current block. The hash value is a potential core foundation and the most important aspect in blockchain technology. It preserves the authenticity of recording and viewing data, as well as the integrity of the blockchain as a whole.

[0074] Smart contract: The concept of a smart contract has three elements: commitment, agreement, and digital form. Therefore, it can extend the application scope of the blockchain to all aspects of financial industry transactions, payments, settlements, and clearings. A smart contract means that when a pre-programmed condition is triggered, the corresponding contract terms are immediately executed, and its working principle is similar to the if-then statement in a computer program.

[0075] Digital resource: A unique encrypted token used to represent media resources (also known as digital assets), which can be traded on the blockchain.

[0076] Account: A blockchain account contains an account address. The account address is a unique address generated on the blockchain using a public-private key pair, used to identify the unique address of the blockchain account.

[0077] Digital resource blockchain: It refers to a blockchain system that supports functions such as the issuance, trading, circulation, and management of digital resource meta - commodities.

[0078] Digital resource meta - item: It is a digital asset with a unique identifier that is generated and issued based on consortium blockchain technology and can only be owned by blockchain accounts that have passed real - name authentication.

[0079] Digital resource metadata: Information used to describe the attributes of digital resource meta - commodities, which is used to indicate the identification, uniform resource identifier, author name, abstract, signature, etc. of digital resource meta - commodities.

[0080] Asset: Rights and interests that can be issued, circulated, stored, and traded on the blockchain for completing payment and settlement services.

[0081] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a blockchain network provided by an embodiment of this application. As Figure 1 shown, the blockchain network may include, but is not limited to, the blockchain network corresponding to the consortium chain. The blockchain network may include multiple blockchain nodes. The multiple blockchain nodes may specifically include blockchain node 10a, blockchain node 10b, blockchain node 10c, blockchain node 10d, …, blockchain node 10n. Among them, when each blockchain node is working properly, it can receive data sent from the outside world and perform block - on - chain processing based on the received data, and can also send data to the outside world. To ensure data intercommunication between each blockchain node, there may be data connections between each blockchain node. For example, there is a data connection between blockchain node 10a and blockchain node 10b, a data connection between blockchain node 10a and blockchain node 10c, and a data connection between blockchain node 10b and blockchain node 10c.

[0082] It can be understood that data or blocks can be transmitted between blockchain nodes through the above - mentioned data connections. The blockchain network can implement data connections between blockchain nodes based on node identifiers. For each blockchain node in the blockchain network, it has a corresponding node identifier, and each of the above - mentioned blockchain nodes can store the node identifiers of other blockchain nodes that are connected to itself, so as to broadcast the obtained data or generated blocks to other blockchain nodes according to the node identifiers of other blockchain nodes in the future.

[0083] For example, blockchain node 10a can maintain a node identifier list as shown in Table 1. This node identifier list stores the node names and node identifiers of other nodes:

[0084] Table 1

[0085] Node Name Node Identifier Node 10a AAA.AAA.AAA.AAA Node 10b BBB.BBB.BBB.BBB Node 10c CCC.CCC.CCC.CCC Node 10d DDD.DDD.DDD.DDD … … Node 10n EEE.EEE.EEE.EEE

[0086] Among them, the node identifier can be the Internet Protocol (IP) address for interconnection between networks and any other information that can be used to identify nodes in the blockchain network. Only the IP address is taken as an example in Table 1 for illustration. For example, blockchain node 10a can send information (such as a block) to blockchain node 10b through the node identifier BBB.BBB.BBB.BBB, and blockchain node 10b can determine that the information is sent by blockchain node 10a through the node identifier AAA.AAA.AAA.AAA.

[0087] In the blockchain, before a block is chained, the block must go through consensus by the consensus nodes in the blockchain network and can be added to the blockchain only after the consensus is passed. It can be understood that when the blockchain is used in some scenarios of commercial institutions, not all participating nodes in the blockchain (i.e., the blockchain nodes in the above blockchain network) have sufficient resources and necessity to become the consensus nodes of the blockchain. For example, in Figure 1 the shown blockchain network, blockchain nodes 10a, 10b, 10c, and 10d can be used as the consensus nodes in the blockchain network. The consensus nodes in the blockchain network participate in the consensus, that is, conduct consensus on the block (including a batch of transactions), that is, vote on the block; while the non-consensus nodes do not participate in the consensus but will help spread the block and voting messages, and synchronize the states with each other, etc.

[0088] It can be understood that when the blockchain network adopts the Byzantine consensus mechanism to achieve the consensus of the block, the assembly of the block and the initiation of the consensus are usually completed by the primary node (also called the block-producing node). In the embodiments of the present application, as Figure 1 shown, the blockchain network can adopt the Byzantine consensus mechanism to achieve the consensus of the block. At this time, a blockchain node with the consensus function, for example, blockchain node 10a, needs to determine the primary node corresponding to the block at the next block height after determining that the block at the current block height is successfully chained, in order to complete the consensus operation for the block at the next block height.

[0089] As Figure 1 shown, the platform server 100 (the server corresponding to the issuer) can have a communication connection with any terminal device in the terminal device cluster (the devices corresponding to the receivers, which can include terminal devices 200a, 200b,..., 200n), and there is also a communication connection between the platform server 100 and the blockchain network. Among them, the above communication connection is not limited to the connection method and can be directly or indirectly connected through a wired communication method, or can be directly or indirectly connected through a wireless communication method, or can also be connected through other methods, which are not limited in the present application.

[0090] The platform server 100 and the terminal device cluster (including terminal devices 200a, 200b, ……, 200n) can be installed with resource clients. When the resource client runs in the platform server 100, it can interact with any blockchain node in the above blockchain network, so that the above blockchain network can receive data requests from the platform server 100.

[0091] Among them, the resource client can be a game application, a video editing application, a social application, an instant messaging application, a live broadcast application, a short video application, a video application, a music application, a shopping application, a novel application, a payment application, a browser, etc., which have the function of displaying data information such as text, images, audio, and video, and can store digital resource identifiers through the resource management service function. Among them, the resource client can be an independent client or an embedded sub-client integrated in a certain client (such as an instant messaging client, a social client, a video client, etc.), which is not limited here.

[0092] The resource client can be used to implement the resource management service function and realize the communication connection with the decentralized application client based on this resource management service function.

[0093] The resource client is a tool for managing and storing user digital resources. For example, digital resources can be transferred to other accounts based on the resource client, and digital resources transferred from other accounts can also be received based on the resource client. The resource client can be a hardware device or a software program. In this application, the resource client of the target object can establish a communication connection with the decentralized application client to implement related operations such as authorized login of the target object.

[0094] It can be understood that with the wide deployment of various decentralized applications on the blockchain and the increase in user activities on the blockchain, when ordinary users use decentralized applications, they can use the blockchain key management tool for login. The address in the blockchain key management tool corresponds to a user on the blockchain, and the decentralized application can obtain the user address from the key management tool through some interfaces, solving the problem that the third-party background cannot trust the user address used when the decentralized application logs in.

[0095] The blockchain node in the embodiment of this application can be any blockchain node in the blockchain network. For ease of understanding, blockchain node 10a is taken as an example for detailed description.

[0096] Specifically, blockchain node 10a can obtain the issuance request from the issuer through the platform server 100. The issuance request can include the issuance information of the first digital resource.

[0097] Among them, the issuer can be a unit or institution that needs to issue the first digital resource, and the issuance information may include the issuance quota of the first digital resource.

[0098] The first digital resource can be a type of digital collectible, that is, a credible digital rights and interests certificate with unique characteristics in the blockchain network, and it is a data object that can record and process multi-dimensional and complex attributes on the blockchain. It is non-fungible and irreplaceable. When a user has the sole ownership right of the first digital resource, it can prove that the digital resource meta-item associated with the identifier of the first digital resource belongs to the user.

[0099] The blockchain node 10a can issue the first digital resource for the issuer based on the issuance information, and the blockchain node 10a can transfer the issued first digital resource to the first account address corresponding to the issuer on the resource client. The issuer has the sole ownership right to the first digital resource.

[0100] It can be understood that the issuance, circulation, storage, and trading of the first digital resource can be carried out in the blockchain network, making the circulation process of the first digital resource public and transparent, while ensuring the security of data transmission and access.

[0101] When the blockchain node 10a receives a transfer request for the first digital resource initiated by the issuer, the blockchain node 10a can transfer the first digital resource to the second account address of the recipient based on the first account address of the issuer (the address corresponding to the issuer on the resource client) and the second account address of the recipient (the address corresponding to the recipient on the resource client) in the transfer request.

[0102] Among them, the recipient can be a user on the issuer's trading platform. After the first digital resource is transferred to the second account address corresponding to the recipient, the recipient has the sole ownership right to the first digital resource.

[0103] It can be understood that the first digital resource can be bound to the account address of the recipient in the resource client through the tokenID in the metadata. For example, after the first digital resource a is transferred to the second account address of the recipient a, the first digital resource a can be bound to the second account address of the recipient a in the resource client through the tokenID in the metadata. After the binding is completed, the recipient a has the sole ownership right to the first digital resource a.

[0104] Digital resource items can be traded on a trading platform. The platform server 100 can be the back-end server of the trading platform. The digital resource items can be generated and issued based on blockchain technology, have passed content compliance reviews, and are digital assets with unique identifiers that can only be owned by blockchain accounts that have passed real-name authentication, or digital rights representing specific items. The digital resource items on the trading platform can report a reported resource value, which can represent the second digital resource required for trading, pre-set in the trading platform, for the digital resource items.

[0105] The second digital resource can be a type of digital asset that can be replaced, is unified, can be infinitely split, can be directly exchanged with each other, and the ownership of the second digital resource can be traced on the blockchain.

[0106] It can be understood that in the specific implementation manners of the present application, for the user data involved, when the present application and the following embodiments are applied to specific products or technologies, user permission or consent needs to be obtained, and the collection, use, and processing of relevant data need to comply with the relevant laws, regulations, and standards in the relevant regions.

[0107] When the blockchain node 10a obtains a transaction request initiated by the recipient for a digital resource item on the issuer's trading platform, the blockchain node 10a can determine the resource value to be transferred of the second digital resource required by the recipient based on the reported resource value reported by the issuer for the digital resource item on the trading platform.

[0108] The blockchain node 10a can determine the target transfer resource value of the second digital resource required by the recipient based on the issuance quota of the first digital resource and the resource value to be transferred. For example, if the reported resource value reported for the digital resource item is 100.00, the recipient a chooses to use the first digital resource a, and the issuance quota of the first digital resource a is 1, the blockchain node 10a can determine the resource value to be transferred as 100.00, and determine the difference between the issuance quota of the first digital resource a and the resource value to be transferred as the target transfer resource value, and the target transfer resource value is 99.00.

[0109] The blockchain node 10a can transfer the first digital resource and the second digital resource with the target transfer resource value to the first account address of the issuer, and transfer the digital resource item to the second account address of the recipient.

[0110] It can be understood that by using the first digital resource as a trading medium for transferring digital resource items and the second digital resource, and leveraging blockchain technology, the first digital resource that is immutable, non-replicable, and traceable endows the user (the recipient) with full control and sole ownership of the first digital resource they possess. It realizes the automation, decentralization, and verifiability of transferring digital resource items and the second digital resource, ensuring the fairness, transparency, and security of transactions.

[0111] The trading medium can refer to the numerical assets that can reduce the amount of digital resource items to be transferred, giving certain discounts or concessions to the users holding them. For example, it can be coupons, vouchers, etc.

[0112] Optionally, the issuer and the trading platform can belong to different institutions or units. For example, they can be the issuing server and the trading server respectively, or they can be integrated into one server, namely the platform server 100. This application embodiment does not limit this here. When the issuer and the trading platform belong to different institutions or units, the issuer can transfer the first digital resource to the recipient, and the recipient can use it on the trading platform. The trading platform can be multiple different application platforms, that is, the first digital resource can be used across platforms, reducing the issuance cost of the first digital resource in multiple trading platforms and improving the trading efficiency of the first digital resource as a trading medium.

[0113] In the embodiment of this application, by the issuer issuing the first digital resource and transferring the first digital resource to the recipient, when the recipient initiates a transaction for digital resource items on the trading platform of the issuer, the first digital resource can be used as a trading medium to reduce the amount of the second digital resource to be transferred for trading digital resource items. The decentralized issuance and management of the trading medium can be achieved through the blockchain network, improving the efficiency and accuracy of trading medium management, reducing the issuance cost of the trading medium, endowing the recipient with full control and sole ownership of the first digital resource they possess, enabling the digital resource to be used as a trading medium, and improving the credibility and security of the trading medium.

[0114] Please refer to Figure 2a , Figure 2a which is a schematic diagram of a data processing scenario based on blockchain provided by the embodiment of this application. Figure 1 .

[0115] As Figure 2a shown, taking the issuer's intention to issue 100 copies of the first digital resource a and 100 copies of the first digital resource b as an example.

[0116] The blockchain node 10a can obtain the issuance request sent by the issuer through the platform server 100. The issuance request can include the issuance information of the first digital resource a and the first digital resource b.

[0117] Among them, the issuer can be a unit or institution that needs to issue the first digital resource. The first digital resource can be a type of digital collectible, that is, a trustworthy digital rights and interests certificate with unique characteristics in the blockchain network, and it is a data object that can record and process multi-dimensional and complex attributes on the blockchain. It is non-fungible and irreplaceable. When a user has the sole ownership of the first digital resource, it can prove that the digital resource meta-item associated with the identifier of the first digital resource belongs to the user.

[0118] The issuance information in the issuance request can be as shown in Table 2:

[0119] Table 2

[0120] Release Information First Digital Resource a First Digital Resource b Release Limit 1 2 Release Quantity 100 100

[0121] Among them, the issuer can issue 100 copies of the first digital resource a with an issuance quota of 1 and 100 copies of the first digital resource b with an issuance quota of 2 through the issuance information. The issuance quotas of the first digital resource a and the first digital resource b are different.

[0122] The blockchain node 10a can call the resource issuance contract based on the issuance information to issue the first digital resource a and the first digital resource b for the issuer.

[0123] Among them, the resource issuance contract can be a type of smart contract on the blockchain, and it can be an automated computer program running on the blockchain. It contains code functions for performing predefined operations under the contract terms, and it can also interact with other contracts, store data, and transfer business resources, etc. The trusted proxy contract is stored on the blockchain in the form of code and can be automatically executed by the blockchain nodes on the blockchain.

[0124] The blockchain node 10a can transfer the 100 copies of the first digital resource a and the 100 copies of the first digital resource b issued to the first account address corresponding to the issuer on the resource client.

[0125] The issuer has the sole ownership right to 100 copies of the first digital resource a and 100 copies of the first digital resource b.

[0126] It can be understood that the issuance, circulation, storage, and trading of the first digital resource can be carried out in the blockchain network, making the circulation process of the first digital resource open and transparent, and at the same time ensuring the security of data transmission and access.

[0127] Please also refer to Figure 2b , Figure 2b which is the second schematic diagram of a data processing scenario based on the blockchain provided by the embodiments of this application.

[0128] Such as Figure 2bAs shown, when blockchain node 10a receives a transfer request initiated by the issuer for the first digital resource a and the first digital resource b, blockchain node 10a can, based on the first account address of the issuer (the address corresponding to the issuer in the resource client) in the transfer request, the address a corresponding to the recipient a (corresponding terminal device 200a) in the resource client, and the address b corresponding to the recipient b (corresponding terminal device 200b) in the resource client.

[0129] Blockchain node 10a can transfer 1 copy of the first digital resource a to the address a of the recipient a, and transfer 1 copy of the first digital resource b to the address b of the recipient b.

[0130] Among them, the recipient a and the recipient b can be users of the issuer's trading platform. After the first digital resource a is transferred to the corresponding address a of the recipient a, the recipient a has the exclusive ownership right to this copy of the first digital resource a. After the first digital resource b is transferred to the corresponding address b of the recipient b, the recipient b has the exclusive ownership right to this copy of the first digital resource b.

[0131] It can be understood that the first digital resource a and the first digital resource b can be bound to the address of the holding user in the resource client through metadata. For example, the above-mentioned 1 copy of the first digital resource a is bound to the address a, and the above-mentioned 1 copy of the first digital resource b is bound to the address b.

[0132] Please also refer to Figure 2c , Figure 2c which is a schematic diagram of a data processing scenario based on blockchain provided by an embodiment of the present application. Figure 3 .

[0133] As Figure 2c shown, digital resource items can be traded in the trading platform, and the platform server 100 can be the back-end server of the trading platform. Digital resource items can be generated and issued based on blockchain technology, and have passed content compliance reviews, and are digital assets with unique identifiers that can only be owned by blockchain accounts that have passed real-name authentication, or digital rights representing specific items. The digital resource items in the trading platform can report reported resource values, and the reported resource values can represent the second digital resources required for trading, which are preset in the trading platform for the digital resource items.

[0134] The second digital resource can be a type of digital asset that can be replaced, has unity, can be infinitely split, can be directly exchanged with each other, and the ownership of the second digital resource can be traced on the blockchain.

[0135] It is understandable that in the specific embodiments of the present application, for the user data involved, when the above and below embodiments of the present application are applied to specific products or technologies, user permission or consent needs to be obtained, and the collection, use, and processing of relevant data need to comply with the relevant laws, regulations, and standards of the relevant regions.

[0136] For ease of understanding, take the example where the recipient a initiates a transaction request through the terminal device 200a.

[0137] When the blockchain node 10a obtains the transaction request initiated by the recipient for the digital resource item in the issuer's trading platform, the blockchain node 10a can determine the to-be-transferred resource value of the second digital resource that the recipient needs to transfer based on the reported resource value reported by the issuer for the digital resource item in the trading platform.

[0138] The blockchain node 10a can determine the target transfer resource value of the second digital resource that the recipient needs to transfer based on the issuance quota of the first digital resource and the to-be-transferred resource value. For example, the reported resource value reported for the digital resource item is 100.00, the recipient a selects to use the first digital resource a, and the issuance quota of the first digital resource a is 1. The blockchain node 10a can determine the to-be-transferred resource value as 100.00, and determine the difference between the issuance quota of the first digital resource a and the to-be-transferred resource value as the target transfer resource value, and the target transfer resource value is 99.00.

[0139] The blockchain node 10a transfers the first digital resource a and the second digital resource with a target transfer resource value of 99.00 to the first account address of the issuer, and transfers the digital resource item to the corresponding address a of the recipient a.

[0140] It is understandable that by using the first digital resource as the trading medium for transferring the digital resource item and the second digital resource, and leveraging blockchain technology, through the first digital resource that is immutable, non-replicable, and traceable, the user (recipient) is given full control and sole ownership of the first digital resource they possess. It realizes the automation, decentralization, and verifiability of transferring the digital resource item and the second digital resource, ensuring the fairness, transparency, and security of the transaction.

[0141] The trading medium can refer to something that can reduce the numerical assets required to be transferred for the digital resource item, giving certain discounts or concessions to the holding users. For example, it can be coupons, vouchers, etc.

[0142] Optionally, the issuer and the trading platform may belong to different institutions or entities. For example, they may be an issuing server and a trading server respectively, or may be integrated into one server, i.e., the platform server 100. The embodiments of the present application do not limit this here. When the issuer and the trading platform belong to different institutions or entities, the issuer may transfer the first digital resource to the recipient, and the recipient may use it on the trading platform. The trading platform may be multiple different application platforms, that is, the first digital resource can be used across platforms, reducing the issuance cost of the first digital resource in multiple trading platforms and improving the trading efficiency of the first digital resource as a trading medium.

[0143] In the embodiments of the present application, by issuing the first digital resource by the issuer and transferring the first digital resource to the recipient, when the recipient initiates a transaction for a digital resource item on the issuer's trading platform, the first digital resource can be used as a trading medium, reducing the value of the second digital resource required to be transferred for trading the digital resource item. The decentralized issuance and management of the trading medium can be achieved through the blockchain network, improving the efficiency and accuracy of trading medium management, reducing the issuance cost of the trading medium, endowing the recipient with full control and sole ownership of the first digital resource they own, and enabling the digital resource to be used as a trading medium, improving the credibility and security of the trading medium.

[0144] On the other hand, the first digital resource can be transferred between recipients, or can be exchanged for the second digital resource, improving the utilization rate of the first digital resource. A business threshold can also be set. When the value of the resource to be transferred of the second digital resource required to be transferred by the recipient is greater than or equal to the business threshold, the recipient has the right to use the first digital resource, expanding new application scenarios for the first digital resource as a trading medium. The first digital resource also supports being used as a trading medium for multiple digital assets, improving the flexibility and scope of use of the trading medium.

[0145] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a blockchain-based data processing method provided by the embodiments of the present application Figure 1 , and this blockchain-based data processing method can be executed by a blockchain node. The blockchain node can be any blockchain node in the blockchain network as shown in Figure 1 . For example, it is the blockchain node 10a. The following will take the execution of this data processing method by the blockchain node as an example for illustration. Among them, this blockchain-based data processing method can at least include the following steps S101 - step S104:

[0146] Step S101, obtain the issuance request of the issuer, and issue the first digital resource with the issuance amount in the issuance request by the issuer; the issuer has the sole ownership right to the first digital resource;

[0147] Specifically, the blockchain node can obtain the issuance request of the issuer. The issuance request may include the issuance information of the first digital resource.

[0148] Among them, the issuer can be a unit or institution that needs to issue the first digital resource, and the issuance information may include the issuance quota of the first digital resource.

[0149] The first digital resource can be a type of digital collectible, that is, a trustworthy digital rights and interests certificate with uniqueness characteristics in the blockchain network, and it is a data object that can record and process multi-dimensional and complex attributes on the blockchain. It is non-fungible and irreplaceable. When the user has the sole ownership right of the first digital resource, it can prove that the digital resource meta-item associated with the identifier of the first digital resource belongs to the user.

[0150] The blockchain node can issue the first digital resource to the issuer based on the issuance information, and the blockchain node can transfer the issued first digital resource to the first account address corresponding to the issuer on the resource client. The issuer has the sole ownership right to the first digital resource.

[0151] It can be understood that the issuance, circulation, storage, and trading of the first digital resource can be carried out in the blockchain network, making the circulation process of the first digital resource open and transparent, while ensuring the security of data transmission and access.

[0152] Step S102, when receiving the transfer request of the issuer for the first digital resource, transfer the first digital resource to the second account address based on the first account address of the issuer and the second account address of the recipient in the transfer request; after the first digital resource is transferred to the second account address, the recipient has the sole ownership right to the first digital resource;

[0153] Specifically, when the blockchain node receives the transfer request of the issuer for the first digital resource, the blockchain node can transfer the first digital resource to the second account address of the recipient based on the first account address of the issuer (the address corresponding to the issuer on the resource client) and the second account address of the recipient (the address corresponding to the recipient on the resource client) in the transfer request.

[0154] Among them, the recipient can be a user on the issuer's trading platform. After the first digital resource is transferred to the second account address corresponding to the recipient, the recipient has the sole ownership right to the first digital resource.

[0155] Digital resource items can be traded on the trading platform. The digital resource items can be generated and issued based on blockchain technology, have passed the content compliance review, and are unique-identified digital assets that can only be owned by blockchain accounts that have passed real-name authentication, or digital rights representing specific items. The digital resource items on the trading platform can report a reported resource value, which can represent the second digital resource required for trading, pre-set in the trading platform, for the digital resource items.

[0156] The second digital resource can be a digital asset that can be replaced, has unity, and can be infinitely split, can be directly exchanged with each other, and the ownership of the second digital resource can be traced on the blockchain.

[0157] It can be understood that the first digital resource can be bound to the account address of the recipient in the resource client through the tokenID in the metadata. For example, after transferring the first digital resource a to the second account address of the recipient a, the first digital resource a can be bound to the second account address of the recipient a in the resource client through the tokenID in the metadata. After the binding is completed, the recipient a has the exclusive ownership right to the first digital resource a. It can also be determined by other methods, and the embodiments of the present application do not limit this here.

[0158] The blockchain node can store the issuance information of the first digital resource as a trading medium through a multi-layer data structure on the blockchain, and the multi-layer data structure can have a format for data storage and reading and writing.

[0159] The blockchain node can assign a classid to each first digital resource. The classid can be determined based on the tokenID of the first digital resource and can be the type of the first digital resource, such as a voucher, coupon, discount coupon, etc. The type of the first digital resource is stored through the class metadata array mapped by the classid.

[0160] The multi-layer data structure can further assign multiple nonceids under each classid. The nonceid can be a resource type identifier, and the issuance information, including the issuance quantity, issuance amount, resource permissions, exchange value, etc., is stored through the nonce metadata array mapped by the nonceid.

[0161] Among them, all classes (all class IDs) share a class metadata array, and all nonces (all nonce IDs) under each class ID share a nonce metadata array. Both the class metadata array and the nonce metadata array can include information such as title, type, description, etc.

[0162] It can be understood that in the embodiments of the present application, the class ID and the nonce ID represent the type of the first digital resource and the specific distribution information, and the metadata of the first digital resource is stored on the chain through two types of nodes or depths. Therefore, different distribution information can be defined for different first digital resources, reducing the distribution threshold of the first digital resource.

[0163] On the other hand, both the class metadata array and the nonce metadata array can be stored and accessed on the chain, designing a new format for the blockchain network that can be uniformly read by both the on-chain smart contract and the off-chain front-end. Users can conveniently view the information of the first digital resource, improving the transparency of the first digital resource.

[0164] Step S103, when a transaction request initiated by the recipient for a digital resource item in the issuer's trading platform is obtained, based on the reported resource value reported by the issuer for the digital resource item in the trading platform, determine the resource value to be transferred of the second digital resource required by the recipient;

[0165] Specifically, when the blockchain node obtains a transaction request initiated by the recipient for a digital resource item in the issuer's trading platform, the blockchain node can determine the resource value to be transferred of the second digital resource required by the recipient based on the reported resource value reported by the issuer for the digital resource item in the trading platform.

[0166] Optionally, if the transaction address for the digital resource item in the transaction request is the second account address of the issuer, the blockchain node can determine that the transaction request is initiated by the recipient in the issuer's trading platform.

[0167] The reported resource value can be the second digital resource required for the transaction, which is pre-set for the digital resource item in the trading platform. The reported resource value can be equal to the resource value to be transferred. The issuer can also adjust the resource value to be transferred through business activities, the active level of users trading digital resource items in the trading platform, etc. The embodiments of the present application do not limit this here.

[0168] Step S104: Based on the issuance quota of the first digital resource and the value of the resource to be transferred, determine the target transfer resource value of the second digital resource that the recipient needs to transfer. Transfer the first digital resource and the second digital resource with the target transfer resource value to the first account address of the issuer, and transfer the digital resource item to the second account address of the recipient.

[0169] Specifically, the blockchain node can determine the target transfer resource value of the second digital resource that the recipient needs to transfer based on the issuance quota of the first digital resource and the value of the resource to be transferred. For example, the difference between the issuance quota of the first digital resource and the value of the resource to be transferred is determined as the target transfer resource value.

[0170] The blockchain node can transfer the first digital resource and the second digital resource with the target transfer resource value to the first account address of the issuer, and transfer the digital resource item to the second account address of the recipient.

[0171] It can be understood that by using the first digital resource as the trading medium for transferring the digital resource item and the second digital resource, and leveraging blockchain technology, the first digital resource, which is immutable, non-replicable, and traceable, endows the user (recipient) with full control and sole ownership of the first digital resource they possess. It realizes the automation, decentralization, and verifiability of transferring the digital resource item and the second digital resource, ensuring the fairness, transparency, and security of the transaction.

[0172] The trading medium can refer to something that can reduce the numerical assets required for transferring the digital resource item, giving certain discounts or concessions to the holding users. For example, it can be coupons, vouchers, etc.

[0173] Optionally, the issuer and the trading platform can belong to different institutions or units. For example, they can be the issuance server and the trading server respectively, or they can be integrated into one server, i.e., the platform server. This application embodiment does not limit this here. When the issuer and the trading platform belong to different institutions or units, the issuer can transfer the first digital resource to the recipient, and the recipient can use it on the trading platform. The trading platform can be multiple different application platforms, that is, the first digital resource can be used across platforms, reducing the issuance cost of the first digital resource in multiple trading platforms and improving the trading efficiency of the first digital resource as a trading medium.

[0174] In an embodiment of the present application, by obtaining an issuance request from an issuer, the issuer issues M first digital resources with the issuance amount in the issuance request; the issuer has the sole attribution right to the first digital resources; when a transfer request for the first digital resources initiated by the issuer is obtained, based on the first account address of the issuer and the second account address of the recipient in the transfer request, the first digital resources are transferred to the second account address; after the first digital resources are transferred to the second account address, the recipient has the sole attribution right to the first digital resources; when a transaction request for a digital resource item initiated by the recipient in the issuer's trading platform is obtained, based on the reported resource value of the digital resource item reported by the issuer in the trading platform, the pending transfer resource value of the second digital resources that the recipient needs to transfer is determined; based on the issuance amount of the first digital resources and the pending transfer resource value, the target transfer resource value of the second digital resources that the recipient needs to transfer is determined, the first digital resources and the second digital resources with the target transfer resource value are transferred to the first account address of the issuer, and the digital resource item is transferred to the second account address of the recipient. It can be seen that in an embodiment of the present application, by issuing the first digital resources by the issuer and transferring the first digital resources to the recipient, when the recipient initiates a transaction for a digital resource item in the issuer's trading platform, the first digital resources can be used as a trading medium, reducing the value of the second digital resources required to transfer the digital resource item. The decentralized issuance and management of the trading medium can be achieved through the blockchain network, improving the efficiency and accuracy of trading medium management, reducing the issuance cost of the trading medium, endowing the recipient with full control and sole attribution right to the first digital resources it owns, and using the digital resources as a trading medium, improving the credibility and security of the trading medium.

[0175] Please refer to Figure 4 , Figure 4 FIG. 2 is a second flowchart of a data processing method based on a blockchain provided by an embodiment of the present application. The data processing method based on the blockchain can be executed by a blockchain node, and the blockchain node can be any blockchain node in a blockchain network as shown in Figure 1 , for example, blockchain node 10a. The following will be described by taking the execution of this data processing method by a blockchain node as an example. Among them, the data processing method based on the blockchain can at least include the following steps S201-S206:

[0176] Step S201, obtain an issuance request from an issuer; the issuance request includes an issuance contract identifier and issuance information; the issuance information includes an issuance quantity M, an issuance amount, and a resource right; call a resource issuance contract based on the issuance contract identifier in the issuance request, and issue M first digital resources with the issuance amount and the resource right to the issuer; the resource right is used to indicate the transfer right of the first digital resources among recipients.

[0177] Specifically, the blockchain node can obtain the issuance request of the issuer. The issuance request may include an issuance contract identifier and the issuance information of the first digital resource.

[0178] Among them, the issuance contract identifier can be used to call the resource issuance contract in the blockchain network. The issuer can be a unit or institution that needs to issue the first digital resource. The first digital resource can be a type of digital collectible, that is, a trustworthy digital rights and interests certificate with unique characteristics in the blockchain network, and it is a data object that can record and process multi-dimensional and complex attributes on the blockchain. It is non-interchangeable and non-substitutable. When a user has the sole ownership right of the first digital resource, it can prove that the digital resource meta-item associated with the identifier of the first digital resource belongs to the user.

[0179] Among them, the resource issuance contract can be a smart contract on the blockchain, which can be an automated computer program running on the blockchain. It contains code functions for performing predefined operations under the contract terms, and can also interact with other contracts, store data, transfer business resources, etc. The trusted proxy contract is stored on the blockchain in the form of code and can be automatically executed by blockchain nodes on the blockchain.

[0180] The issuance information may include the issuance quantity M of the first digital resource, the issuance amount, and the resource permission. The resource permission can be used to indicate the transfer permission of the first digital resource among the recipients, that is, the first digital resource with the transfer permission can be transferred among different recipients.

[0181] The blockchain node can call the resource issuance contract based on the issuance contract identifier in the issuance request, and issue M first digital resources with the issuance amount and resource permission to the issuer. The blockchain node can transfer the issued first digital resources to the first account address corresponding to the issuer on the resource client. The issuer has the sole ownership right to the first digital resource. Issuing the first digital resource with resource permission means that the first digital resource can be transferred among different recipients.

[0182] It can be understood that the issuance, circulation, storage, and trading of the first digital resource can be carried out in the blockchain network, making the circulation process of the first digital resource public and transparent, while ensuring the security of data transmission and access.

[0183] Step S202, when receiving the transfer request of the issuer for the first digital resource, transfer the first digital resource to the second account address based on the first account address of the issuer and the second account address of the recipient in the transfer request; after the first digital resource is transferred to the second account address, the recipient has the sole ownership right to the first digital resource;

[0184] Specifically, when a blockchain node receives a transfer request for the first digital resource initiated by the issuer, the blockchain node can transfer the first digital resource to the second account address of the recipient based on the first account address of the issuer (the address corresponding to the issuer on the resource client) and the second account address of the recipient (the address corresponding to the recipient on the resource client) in the transfer request.

[0185] Among them, the recipient can be a user of the issuer's trading platform. After the first digital resource is transferred to the corresponding second account address of the recipient, the recipient has the sole ownership right to the first digital resource.

[0186] Digital resource items can be traded in the trading platform. Digital resource items can be generated and issued based on blockchain technology, have passed content compliance reviews, and are unique-identified digital assets that can only be owned by blockchain accounts that have passed real-name authentication, or digital rights representing specific items. The digital resource items in the trading platform can report a reported resource value, and the reported resource value can represent the second digital resource required for trading, which is pre-set in the trading platform for the digital resource items.

[0187] The second digital resource can be a type of digital asset that can be replaced, has unity, can be infinitely split, can be directly exchanged with each other, and the ownership of the second digital resource can be traced on the blockchain.

[0188] The process of the blockchain node transferring the first digital resource can be as follows: Based on the proxy contract identifier in the transfer request, call the trusted proxy contract, and use the authorization function in the trusted proxy contract to verify the signature information in the transfer request; the signature information is obtained by signing the first digital resource with the private key of the issuer; when the signature verification is successful, authorize the first digital resource to the trusted proxy contract, call the transfer function in the trusted proxy contract, and based on the first account address of the issuer and the second account address of the recipient in the transfer request, transfer the authorized first digital resource to the second account address.

[0189] Specifically, the transfer request can include a proxy contract identifier, and the blockchain node can call the trusted proxy contract through the proxy contract identifier, and use the authorization function in the trusted proxy contract to verify the signature information in the transfer request.

[0190] Among them, the signature information is obtained by the issuer signing the first digital resource with the private key of the issuer. The trusted proxy contract can be a type of smart contract on the blockchain, which can be an automated computer program running on the blockchain, and can contain execution functions for performing predefined operations under the contract terms, such as including authorization functions, transfer functions, etc.

[0191] The authorization function can be a method in the trusted proxy contract that supports signature parameters, used to verify and execute the conditions stipulated in the contract for trusted transactions. The transfer function can be used to transfer the exclusive ownership right of digital resources based on the first account address and the second account address in the transfer request.

[0192] The process of signature verification can be as follows: Obtain the public key of the first account address through the authorization function in the trusted proxy contract, and based on the public key of the first account address, perform a decryption operation on the signature information to obtain the hash value to be verified; Generate the target hash value of the first digital resource; If the hash value to be verified is the same as the target hash value, it is determined that the signature verification is successful; If the hash value to be verified is different from the target hash value, it is determined that the signature verification fails, and an error prompt message is returned to the issuer.

[0193] Specifically, the blockchain node obtains the public key of the first account address through the authorization function in the trusted proxy contract, and based on the public key of the first account address, performs a decryption operation on the signature information to obtain the hash value to be verified. The blockchain node can calculate the hash digest of the first digital resource to obtain the target hash value of the first digital resource.

[0194] The blockchain node can compare the hash value to be verified with the target hash value.

[0195] If the hash value to be verified is the same as the target hash value, it is determined that the signature verification is successful; If the hash value to be verified is different from the target hash value, it is determined that the signature verification fails, and the blockchain node can return an error prompt message to the issuer.

[0196] If the signature verification is successful, the blockchain node can authorize the first digital resource for the trusted proxy contract, call the transfer function in the trusted proxy contract, and the blockchain node can transfer the authorized first digital resource to the second account address based on the first account address of the issuer and the second account address of the recipient in the transfer request.

[0197] It can be understood that the first digital resource can be bound to the account address of the recipient in the resource client through the tokenID in the metadata. For example, after transferring the first digital resource a to the second account address of the recipient a, the first digital resource a can be bound to the second account address of the recipient a in the resource client through the tokenID in the metadata. After the binding is completed, the recipient a has the exclusive ownership right to the first digital resource a. It can also be determined by other methods, and the embodiments of the present application do not limit this here.

[0198] Step S203: If the value of the resource to be transferred of the second digital resource required by the recipient is greater than or equal to the service threshold, then the difference between the issuance quota of the first digital resource and the value of the resource to be transferred is determined as the target transfer resource value of the second digital resource required by the recipient; the service threshold is set by the issuer for the first digital resource.

[0199] Specifically, the issuer can set the service threshold and the reported resource value for using the first digital resource for digital resource items in the trading platform. Only when the value of the resource to be transferred determined by the recipient is greater than or equal to the service threshold does the recipient have the right to use the first digital resource.

[0200] When the blockchain node obtains a transaction request initiated by the recipient for a digital resource item in the issuer's trading platform, the blockchain node can determine the value of the resource to be transferred of the second digital resource required by the recipient based on the reported resource value reported by the issuer for the digital resource item in the trading platform.

[0201] Among them, the reported resource value can be the second digital resource required for the transaction, which is pre-set for the digital resource item in the trading platform. The reported resource value can be equal to the value of the resource to be transferred. The issuer can also adjust the value of the resource to be transferred through business activities, the active level of users trading digital resource items in the trading platform, etc. This application embodiment does not limit this here.

[0202] If the value of the resource to be transferred of the second digital resource required by the recipient is greater than or equal to the service threshold, then the blockchain node can determine the difference between the issuance quota of the first digital resource and the value of the resource to be transferred as the target transfer resource value of the second digital resource required by the recipient.

[0203] Optionally, if the value of the resource to be transferred of the second digital resource required by the recipient is greater than or equal to the service threshold, and the recipient holds multiple first digital resources. For example, the recipient holds 1 copy of the first digital resource a and 1 copy of the first digital resource b. The issuance quota of the first digital resource a is 1, and the issuance quota of the second digital resource b is 2. The recipient can select the digital resource to be used between the first digital resource a and the second digital resource b. If the reported resource value reported by the issuer for the digital resource item in the trading platform is 100, when the recipient selects to use the first digital resource a, the blockchain node can determine that the target transfer resource value is 99, and when the recipient selects to use the first digital resource b, the blockchain node can determine that the target transfer resource value is 98.

[0204] The blockchain node can determine the target transfer resource value of the second digital resource that the recipient needs to transfer based on the issuance quota of the first digital resource and the value of the resource to be transferred. For example, the difference between the issuance quota of the first digital resource and the value of the resource to be transferred is determined as the target transfer resource value.

[0205] The blockchain node can transfer the first digital resource and the second digital resource with the target transfer resource value to the first account address of the issuer, and transfer the digital resource item to the second account address of the recipient.

[0206] Optionally, if the transaction address for the digital resource item in the transaction request is the second account address of the issuer, the blockchain node can determine that the transaction request is a request initiated by the recipient on the issuer's trading platform.

[0207] It can be understood that by using the first digital resource as the trading medium for transferring the digital resource item and the second digital resource, and leveraging blockchain technology, through the first digital resource that is immutable, non-replicable, and traceable, the user (recipient) is given full control and sole ownership of the first digital resource they possess. It realizes the automation, decentralization, and verifiability of transferring the digital resource item and the second digital resource, ensuring the fairness, transparency, and security of the transaction.

[0208] The trading medium can refer to something that can reduce the numerical assets required for the transfer of the digital resource item, giving certain discounts or concessions to the users holding it. For example, it can be coupons, vouchers, etc.

[0209] Optionally, the issuer and the trading platform can belong to different institutions or units. For example, they can be a distribution server and a trading server respectively, or they can be integrated into one server, i.e., a platform server. This application embodiment does not limit this here. When the issuer and the trading platform belong to different institutions or units, the issuer can transfer the first digital resource to the recipient, and the recipient can use it on the trading platform. The trading platform can be multiple different application platforms, that is, the first digital resource can be used across platforms, reducing the distribution cost of the first digital resource in multiple trading platforms and improving the trading efficiency of the first digital resource as a trading medium.

[0210] Step S204, if the value of the resource to be transferred of the second digital resource that the recipient needs to transfer is less than the service threshold, it is determined that the first digital resource does not have the usage permission for the transaction request, transfer the second digital resource with the value of the resource to be transferred to the first account address of the issuer, and transfer the digital resource item to the second account address of the recipient.

[0211] Specifically, if the value of the resource to be transferred of the second digital resource required by the recipient is less than the service threshold, the blockchain network may determine that the first digital resource does not have the usage permission for the transaction request, and the recipient cannot use the first digital resource when trading the above digital resource item.

[0212] The recipient may choose not to use the first digital resource and continue the transaction. The blockchain node may transfer the second digital resource with the value of the resource to be transferred to the first account address of the issuer and transfer the digital resource item to the second account address of the recipient.

[0213] Step S205: When the first digital resource held by the recipient has the transfer permission and the blockchain node obtains a transfer request initiated by the recipient for the first digital resource, transfer the first digital resource to the third account address based on the second account address of the recipient and the third account address of the transferee in the transfer request; after the first digital resource is transferred to the third account address, the transferee has the sole ownership permission for the first digital resource.

[0214] Specifically, the first digital resource issued by the discoverer has the transfer permission, which means the first digital resource can be transferred between different recipients. For example, recipient a can transfer the first digital resource held by it to transferee c.

[0215] When the first digital resource held by the recipient has the transfer permission and the blockchain node obtains a transfer request initiated by the recipient for the first digital resource, the blockchain node transfers the first digital resource to the third account address based on the second account address of the recipient and the third account address of the transferee in the transfer request.

[0216] For example, if recipient a holds the first digital resource with the transfer permission, recipient a can send a transfer request for the first digital resource. The blockchain node can determine the address of recipient a (the second account address) and the address of transferee c (the third account address) in the transfer request, and the blockchain node can transfer the first digital resource to the third account address. After the first digital resource is transferred to the third account address, transferee c has the sole ownership permission for the first digital resource.

[0217] During the process of transferring the first digital resource, the signature information of the recipient will also be verified. The transfer process and the signature verification process can refer to the specific description in step S202 above and will not be elaborated here.

[0218] It can be understood that the first digital resource can be transferred among recipients, improving the utilization rate of the first digital resource. A business threshold can also be set. When the value of the resource to be transferred of the second digital resource required by the recipient is greater than or equal to the business threshold, the recipient will have the right to use the first digital resource, expanding new application scenarios for the first digital resource as a trading medium. The first digital resource also supports being used as a trading medium for various digital assets, improving the flexibility and scope of use of the trading medium.

[0219] Step S206: When a redemption request for the first digital resource initiated by the recipient is obtained, the second digital resource with a redemption value is issued to the second account address in the redemption request, and the first digital resource is cancelled; the redemption value is determined based on the first digital resource.

[0220] Specifically, the issuer can set the redemption value of the first digital resource in the issuance information. After the first digital resource with the set redemption value is issued, a redemption request can be sent to exchange the first digital resource for the second digital resource with the redemption value.

[0221] When the blockchain node obtains a redemption request for the first digital resource initiated by the recipient, the blockchain node can issue the second digital resource with the redemption value to the second account address in the redemption request. After issuing the second digital resource with the redemption value, the blockchain node can cancel the first digital resource.

[0222] In an embodiment of the present application, by obtaining an issuance request from an issuer, the issuer issues a first digital resource with an issuance amount in the issuance request; the issuer has the sole attribution right to the first digital resource; when a transfer request for the first digital resource initiated by the issuer is obtained, based on the first account address of the issuer and the second account address of the recipient in the transfer request, the first digital resource is transferred to the second account address; after the first digital resource is transferred to the second account address, the recipient has the sole attribution right to the first digital resource; when a transaction request for a digital resource item initiated by the recipient in the issuer's trading platform is obtained, based on the reported resource value of the digital resource item reported by the issuer in the trading platform, the pending transfer resource value of the second digital resource to be transferred by the recipient is determined; based on the issuance amount of the first digital resource and the pending transfer resource value, the target transfer resource value of the second digital resource to be transferred by the recipient is determined, the first digital resource and the second digital resource with the target transfer resource value are transferred to the first account address of the issuer, and the digital resource item is transferred to the second account address of the recipient. Thus, in the embodiment of the present application, by issuing the first digital resource by the issuer and transferring the first digital resource to the recipient, when the recipient initiates a transaction for a digital resource item in the issuer's trading platform, the first digital resource can be used as a trading medium, reducing the value of the second digital resource required to transfer the digital resource item. The decentralized issuance and management of the trading medium can be achieved through the blockchain network, improving the efficiency and accuracy of trading medium management, reducing the issuance cost of the trading medium, endowing the recipient with full control and sole attribution right to the first digital resource it owns, using the digital resource as a trading medium, and improving the credibility and security of the trading medium.

[0223] On the other hand, the first digital resource can be transferred between recipients, or exchanged for the second digital resource, improving the utilization rate of the first digital resource. A service threshold can also be set. When the pending transfer resource value of the second digital resource to be transferred by the recipient is greater than or equal to the service threshold, the recipient has the right to use the first digital resource, expanding new application scenarios for the first digital resource as a trading medium. The first digital resource also supports being used as a trading medium for multiple digital assets, improving the flexibility and scope of use of the trading medium.
