Description

Technical Field

[0001] The present application relates to fields such as blockchain technology, and in particular to a business processing method, device, equipment, and storage medium. Background Art

[0002] During the business processing process, the business entrusting party (i.e., the user corresponding to the first device) can entrust the business to be processed to the business service party (i.e., the user corresponding to the second device) by paying digital resources to the business service party. This can reduce the business processing pressure of the business entrusting party and improve business processing efficiency.

[0003] In practice, after the service provider completes the business processing, the client is required to manually review the completed business. Only after the review is passed will the client pay the digital resources to the service provider. This review method is relatively inefficient, resulting in relatively low business processing efficiency. Furthermore, there is a certain time lag between commissioning the business and completing the business processing. If the client and service provider use different types of digital resources, the exchange ratio between the digital resources used by the service provider and the client can easily change during this time lag, which can easily cause resource losses to either the service provider or the client. Summary of the Invention

[0004] The embodiments of the present application provide a business processing method, apparatus, device, and storage medium, which can improve business processing efficiency and avoid resource loss to business service providers or business entrusting parties.

[0048] In this application, the node device in the blockchain network can pre-lock the resource certificate of the business entrusting party in the address of the resource locking contract on the blockchain. The resource certificate is used to indicate that after the business service party completes the processing of the target business, the second amount of the second type of digital resources will be paid to the business service party. The resource certificate is purchased by the business entrusting party, which is equivalent to the business entrusting party having frozen (locked) the digital resources required for processing the target business in the address of the resource locking contract in advance. This can avoid the change in the exchange rate between the digital resources used by the business entrusting party and the business service party, causing resource losses to the business entrusting party or the business service party. In addition, the unlocking conditions of the resource certificate are generated according to the processing requirement information of the target business, and the business processing certificate for the target business is generated according to the unlocking conditions, and the business processing certificate is sent to the second device corresponding to the business service party. The business service provider processes the target business and generates processing certification information for the target business. Upon receiving the processing certification information and business processing voucher provided by the business service provider, the business service provider automatically verifies whether the unlocking conditions of the resource voucher are met based on the received business processing voucher and processing certification information. If the unlocking conditions are met, the resource voucher is unlocked, and the second category digital resource is paid to the business service provider based on the resource voucher and the second quantity of the second category digital resource. This shows that the present application can automatically verify the business service provider without the need for human intervention, thereby improving business processing efficiency.

[0056] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] First, let's introduce the blockchain data processing system used in this application. Figure 1 , Figure 1 This is a schematic diagram of the structure of a blockchain data processing system provided in an embodiment of the present application. The blockchain data processing system may include a blockchain network and one or more terminals. The present application does not limit the number of terminals, and the number of terminals can be set according to demand. Figure 1 The example is described with three terminals, including terminal 111, terminal 112 and terminal 113.

[0058] The blockchain network is an end-to-end decentralized network composed of multiple node devices (also called blockchain nodes). The number of node devices in the blockchain network can be deployed according to actual needs. This application does not limit the number of node devices. Figure 1 The blockchain network includes four node devices as an example for explanation, and the four node devices are node device 101, node device 102, node device 103 and node device 104.

[0059] It is understandable that the functions involved in each node device in the blockchain network include:

[0060] 1) Routing: A basic function of a node device, used to support communication between node devices.

[0061] For example, Figure 1 As shown, data or blocks can be transferred between node devices through a network connection. The network connection between the above-mentioned node devices can transmit data based on node identification. Each node device has a node identification corresponding to it, and each of the above-mentioned node devices can store the node identifications of other node devices connected to it, so that the acquired data or generated blocks can be broadcast to other node devices based on the node identifications of other node devices. For example, node device 101 can maintain a node identification list, which stores the node names and node identifications of other node devices, as shown in Table 1:

[0062] Table 1

[0063] Node Name Node ID Node device 101 aaaa Node device 102 bbbb Node device 103 cccc Node device 104 dddd … …

[0064] As shown in Table 1, assuming that the node identification of node device 101 is aaaa, node device 101 can send a data synchronization request to node device 102 through aaaa, and node device 102 can know that the data synchronization request is sent by node device 101 through node identification aaaa; similarly, node device 102 can send transaction data A to node device 101 through node identification bbbb, and node device 101 can know that the transaction data A is sent by node device 102 through node identification bbbb. The same is true for data transmission between other node devices, so they will not be elaborated one by one.

[0065] 2) Applications, deployed in the blockchain, implement specific services based on actual business needs, record data related to the implementation of functions to form record data, carry digital signatures in the record data to indicate the source of the task data, and send the record data to other node devices in the blockchain network for other node devices to add the record data to a temporary block when they successfully verify the source and integrity of the record data.

[0066] For example, the services implemented by the application include:

[0067] 2.1) Resource Management Services: Node devices may include resource clients, which implement resource management service functions and, based on these functions, establish communication connections with decentralized application clients. A resource client is a tool responsible for managing and storing a user's digital resources. For example, digital resources can be transferred to other accounts or received from other accounts. This resource client can be either a hardware device or a software program.

[0068] It is understandable that with the widespread deployment of various decentralized applications on the blockchain and the increase in user activities on the blockchain, general users can use blockchain key management tools to log in when using decentralized applications. The address in the blockchain key management tool corresponds to a user on the blockchain. The decentralized application can obtain the user address from the key management tool through some interfaces. In order to solve the problem that the Dapp background cannot trust the user address used when logging in to the decentralized application.

[0069] 2.2) Shared ledgers are used to store, query, and modify account data (i.e., transaction data). Records of operations on account data are sent to other nodes in the blockchain network. After verification, other nodes acknowledge the validity of the account data by storing the recorded data in a temporary block. They can also send a confirmation to the node device that initiated the operation.

[0070] For example, each node device can receive data to be recorded when performing normal operations, and maintain a shared ledger (i.e., blockchain) based on the received data to be recorded. In order to ensure information intercommunication within the shared ledger network, a network connection can exist between each node device in the shared ledger network, and data can be transmitted between the node devices through the above network connection. For example, when any node device in the shared ledger network receives data to be recorded, the other node devices in the shared ledger network will verify the data to be recorded according to the consensus algorithm, and after successful verification (i.e., after consensus is reached), the data to be recorded will be stored as data in the shared ledger, so that the data stored on all node devices in the shared ledger network are consistent.

[0071] 2.3) Smart contracts are computerized protocols that can execute the terms of a contract. They are implemented through code deployed on a shared ledger that is executed when certain conditions are met. Based on actual business needs, the code is used to complete automated transactions, such as querying the logistics status of a buyer's purchased goods and transferring the buyer's digital assets to the merchant's address after the buyer signs for the goods. Of course, smart contracts are not limited to executing contracts for transactions, but can also execute contracts that process received information.

[0072] Among them, the blockchain maintained by node device 101, node device 102, node device 103 and node device 104 may include a resource locking contract, and the resource locking contract may refer to a smart contract.

[0073] Optionally, the resource lock contract may have the following functions: (1) Locking function. The resource lock contract may lock the resource certificate in the address of the resource lock contract; that is, after the resource certificate is transferred to the address of the resource lock contract, the resource certificate cannot be transferred out of the address of the resource lock contract, nor can it be exchanged for digital resources unless the unlocking conditions are met. (2) Unlocking function. When the resource lock contract locks the resource certificate, it will generate an unlocking condition for the resource certificate. When the device that unlocks the resource certificate meets the unlocking condition, the resource lock contract can unlock the resource certificate. That is, when the unlocking condition is met, the resource certificate can be transferred out of the address of the resource lock contract by the node device, and can also be exchanged for digital resources.

[0074] The resource locking contract may be jointly formulated by the business service provider and the business entrusting party, or the resource locking contract may be formulated by a node device in the blockchain network.

[0075] Any of the above terminals can be used to publish a target business to be processed, or to process a target business. Typically, the terminal used to publish a target business can be referred to as the first device corresponding to the business entrusting party, and the terminal used to process the target business can be referred to as the second device corresponding to the business service provider. The target business can refer to the business to be processed, such as cross-border cargo transportation, technical software development, etc.

[0076] In one embodiment, the digital resources used by the first device are first-category digital resources, and the digital resources used by the second device are second-category digital resources. The first-category digital resources and the second-category digital resources may be different. The digital resources may include legal tender, digital assets, etc. For example, the first-category digital resource may be legal tender A, and the second-category digital resource may be legal tender B. The first-category digital resources and the second-category digital resources are different.

[0077] It should be noted that a resource voucher can refer to a digital asset anchored by a certain type of digital resource. In practice, the resource voucher can refer to a digital asset anchored by a second type of digital resource. The stability of the exchange ratio between the resource voucher and the second type of digital resource is greater than a stability threshold. In other words, when the value of the second type of digital resource increases, the value of the resource voucher also increases; when the value of the second type of digital resource decreases, the value of the resource voucher also decreases; the exchange ratio between the resource voucher and the second type of digital resource remains within a certain numerical range. The stability threshold can be jointly determined by the service provider and the service entrusting party.

[0078] It should be noted that the business processing credential may refer to a digital credential used to record the unlocking conditions of the target business. The business processing credential may include the unlocking conditions, device information of the first device, device information of the second device, etc.

[0079] The business processing voucher may be generated by a business processing voucher contract; the business processing voucher contract may be jointly developed by the business service provider and the business entrusting party, or the business processing voucher contract may be developed by a node device in the blockchain network. The business processing voucher contract is used to generate a business processing voucher for the target business based on the unlocking conditions of the resource voucher.

[0080] It should be noted that node device 101, node device 102, node device 103, and node device 104 can be an independent physical server, or a server cluster or distributed system composed of at least two physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms. Terminals 111, 112, and 113 can include: smart phones, tablet computers, laptops, desktop computers, intelligent voice interaction devices, smart home appliances (e.g., smart TVs), wearable devices, and vehicle-mounted terminals with data processing capabilities.

[0081] Further, see Figure 2 , Figure 2 This is a flowchart of a business processing method provided by an embodiment of the present application. Figure 1 The method may be performed by any node device in the blockchain network.

[0082] S101. Obtain processing requirement information of a target business to be processed in a first device, lock a resource certificate of the first device to the address of a resource locking contract on a blockchain, and generate unlocking conditions for the resource certificate based on the processing requirement information.

[0083] It should be noted that the above-mentioned resource certificate can be purchased by the first device from the certificate issuer using the first quantity of the first type of digital resources. The above-mentioned certificate issuer may include a bank, an enterprise that can serve as a bank to issue resource certificates, etc. The above-mentioned processing requirement information may include a restricted completion time and processing quality requirements for the target business; the above-mentioned restricted completion time may refer to the deadline for the second device to complete the processing of the target business, and the above-mentioned processing quality requirements may refer to the completion conditions of the target business. For example, when the above-mentioned restricted completion time is set to January 1, 2024, the second device must complete the processing of the target business before January 1, 2024. When the target business is a cross-border cargo transportation business, the above-mentioned processing quality requirements can be set to obtain an import declaration form from a certain customs, etc.

[0084] It should be noted that the aforementioned locking can refer to transferring the resource certificate to the address of the resource locking contract. Until the unlocking conditions are met, the resource certificate cannot be transferred out of the resource locking contract address or redeemed for digital resources. The unlocking conditions may also include the target business completion time limit and processing quality requirements.

[0085] It is understandable that before the first device entrusts the above-mentioned target business to be processed, the user corresponding to the first device (i.e., the business entrusting party) can jointly determine with the user corresponding to the second device (i.e., the business service party) the digital resources available for processing the above-mentioned target business. When the first device determines that the second device can obtain a second quantity of the second type of digital resources after processing the above-mentioned target business, the first device can determine the first quantity of the first type of digital resources that the first device needs to pay based on the current exchange rate between the first type of digital resources and the second type of digital resources. The first device can use the first quantity of the first type of digital resources to purchase a resource certificate of equal value to the second quantity of the second type of digital resources from the certificate issuer. For example, the first type of digital resource is legal tender A, and the second type of digital resource is legal tender B. The resource certificate can refer to a digital asset anchored by legal tender B. The exchange ratio between legal tender A and legal tender B is 1:2; the exchange ratio between the resource certificate and legal tender B is 1:1. When the first device determines that the second device can obtain 100 pieces of legal tender B after processing the above-mentioned target business, the first device can determine 50 pieces of legal tender A that the first device needs to pay based on the exchange ratio of 2:1 between legal tender A and legal tender B; therefore, the first device can use the 50 pieces of legal tender A to purchase resource certificates of equal value to 100 pieces of legal tender B from the certificate issuer.

[0086] Furthermore, after the first device obtains a resource certificate of equal value to the second quantity of the second type of digital resources, the first device can send the processing requirement information and resource certificate of the target business to be processed to the node device. After the node device receives the processing requirement information and the resource certificate, it can transfer the resource certificate to the address of the resource locking contract on the blockchain for locking; the node device can input the restricted completion time and processing quality requirements in the processing requirement information into the resource locking contract, and obtain the unlocking conditions for unlocking the resource certificate from the address of the resource locking contract. The first device converts the digital resources that can be obtained after the target business processing is completed into resource certificates in advance; therefore, by locking the resource certificate, the exchange rate between the first digital resource and the second digital resource can be locked, so as to avoid resource losses to the users corresponding to the first device and the users corresponding to the second device when the exchange rate between the first type of digital resources and the second type of digital resources drops.

[0087] S102: Generate a service processing credential for the target service according to the unlocking condition, and send the service processing credential to the second device.

[0088] It should be noted that the business processing voucher of the target business is used to instruct the second device to process the target business and generate processing proof information for the target business. The business processing voucher can be used to record the unlocking conditions of the target business, so that the second device can accurately understand the processing standards of the target business through the business processing voucher. The above-mentioned processing proof information may refer to the proof materials of the second device in the process of processing the target business. The format of the proof materials may include pictures, text, documents, etc. For example, when the target business is a cross-border cargo transportation business, the above-mentioned processing proof information may be an import declaration form of a customs, etc.

[0089] It is understood that the node device can enter the unlocking conditions of the resource voucher into the business processing voucher contract and, based on the business processing voucher contract, generate a business processing voucher for the target business. The node device transmits the business processing voucher for the target business to the second device. After receiving the business processing voucher, the second device can obtain the unlocking conditions of the resource voucher from the business processing voucher; based on the unlocking conditions, the second device can generate processing proof information for the target business during the processing of the target business.

[0090] S103: When the processing certification information and the business processing credential sent by the second device are received, the relationship between the second device and the unlocking condition is verified according to the received business processing credential and processing certification information to obtain a relationship verification result.

[0091] It should be noted that the second device can simultaneously receive multiple service delegations. Therefore, the second device can simultaneously receive service processing vouchers corresponding to multiple services, and based on each service processing voucher, process the service corresponding to each service processing voucher and generate processing certification information corresponding to each service processing voucher. Therefore, the node device can receive multiple service processing vouchers and multiple pieces of processing certification information sent by the second device.

[0092] It should be noted that the above-mentioned relationship verification result may include a relationship verification result indicating that the second device meets the unlocking condition; the above-mentioned relationship verification result may also include a relationship verification result indicating that the second device does not meet the unlocking condition.

[0093] It is understandable that when the node device receives the processing proof information and business processing credentials sent by the second device, the node device needs to verify whether the received business processing credentials are the business processing credentials of the target business. Therefore, when the node device verifies that the received business processing credentials are the business processing credentials of the target business, the node device can verify whether the second device meets the unlocking conditions based on the unlocking conditions in the resource locking contract and the received processing proof information. When the node device verifies that the second device meets the unlocking conditions, a relationship verification result is generated to indicate that the second device meets the unlocking conditions; when the node device verifies that the second device does not meet the unlocking conditions, a relationship verification result is generated to indicate that the second device does not meet the unlocking conditions. The node device can automatically verify whether the second device meets the unlocking conditions through the resource locking contract without manual intervention; this can reduce the time cost consumed by manual verification, reduce verification errors caused by manual verification, and improve the efficiency of business processing.

[0094] S104. When the relationship verification result indicates that the second device meets the unlocking condition, unlock the resource certificate from the address of the resource locking contract, and control the certificate issuer to pay the second type of digital resources to the second device based on the resource certificate, the received business processing certificate, and the second quantity of the second type of digital resources.

[0095] It should be noted that when the above relationship verification result indicates that the second device meets the unlocking conditions, it indicates that the resource certificate can be unlocked from the address of the resource locking contract. When the above relationship verification result indicates that the second device does not meet the unlocking conditions, it indicates that the resource certificate cannot be unlocked from the address of the resource locking contract.

[0096] It is understandable that when the relationship verification result indicates that the second device meets the unlocking conditions, the node device can unlock the resource certificate locked in the address of the resource locking contract. The node device can transfer the second quantity of the second type of digital resources from the account address of the certificate issuer to the account address of the second device based on the resource certificate; and destroy the received business processing certificate. After determining that the second device meets the unlocking conditions, the node device can directly unlock the resource certificate and control the certificate issuer to pay the second type of digital resources to the second device, so that the second device can quickly obtain digital resources and improve the efficiency of business processing.

[0097] In this application, the node device in the blockchain network can pre-lock the resource certificate of the business entrusting party in the address of the resource locking contract on the blockchain. The resource certificate is used to indicate that after the business service party completes the processing of the target business, the second amount of the second type of digital resources will be paid to the business service party. The resource certificate is purchased by the business entrusting party, which is equivalent to the business entrusting party having frozen (locked) the digital resources required for processing the target business in the address of the resource locking contract in advance. This can avoid the change in the exchange rate between the digital resources used by the business entrusting party and the business service party, causing asset losses to the business entrusting party or the business service party. In addition, the unlocking conditions of the resource certificate are generated according to the processing requirement information of the target business, and the business processing certificate for the target business is generated according to the unlocking conditions, and the business processing certificate is sent to the second device corresponding to the business service party. The business service provider processes the target business and generates processing certification information for the target business. Upon receiving the processing certification information and business processing voucher provided by the business service provider, the business service provider automatically verifies whether the unlocking conditions for the resource voucher are met based on the received business processing voucher and processing certification information. If the unlocking conditions are met, the resource voucher is unlocked, and the second category digital resource is paid to the business service provider based on the resource voucher and the second quantity of the second category digital resource. This allows for automated verification of the business service provider, eliminating the need for human intervention and improving business processing efficiency.

[0098] Further, see Figure 3 , Figure 3 This is a flowchart of a business processing method provided by an embodiment of the present application. Figure 1 The method may be performed by any node device in the blockchain network.

[0099] S201. Obtain processing requirement information of a target business to be processed in a first device, lock a resource certificate of the first device to the address of a resource locking contract on a blockchain, and generate unlocking conditions for the resource certificate based on the processing requirement information.

[0100] S202: Generate a service processing credential for the target service according to the unlocking condition, and send the service processing credential to the second device.

[0101] Optionally, when receiving the financing application information regarding the above-mentioned target business sent by the above-mentioned second device, obtain the mortgage ratio from the above-mentioned financing application information; generate a business processing certificate including the above-mentioned mortgage ratio based on the above-mentioned unlocking conditions and the above-mentioned mortgage ratio; and send the business processing certificate including the above-mentioned mortgage ratio to the above-mentioned second device.

[0102] It should be noted that the above-mentioned mortgage ratio is used to instruct the above-mentioned second device to mortgage the above-mentioned third quantity of the second type of digital resources to the third device. The above-mentioned third device is a device that provides financing for the above-mentioned target business to the above-mentioned second device, and the ratio between the above-mentioned third quantity and the above-mentioned second quantity is the above-mentioned mortgage ratio. The above-mentioned financing application information may include the mortgage ratio, device information of the third device, etc. The business processing certificate including the above-mentioned mortgage ratio may include the unlocking conditions of the target business, and the ratio of the second type of digital resources that the second device and the third device can obtain respectively. The ratio of the second type of digital resources that the second device and the third device can obtain respectively can be obtained from the above-mentioned mortgage ratio.

[0103] It is understood that the second device can send financing application information to the node device. After receiving the financing application information, the node device obtains the collateral ratio from the financing application information, enters the unlocking conditions and the collateral ratio into the business processing voucher contract, and generates a business processing voucher including the collateral ratio through the business processing voucher contract. The node device then sends the business processing voucher including the collateral ratio to the second device.

[0104] Optionally, based on the unlocking conditions, a business processing certificate for the target business is generated and sent to the second device. Upon receiving the business processing certificate for the target business and the financing application information from the second device, the business processing certificate is destroyed; the collateral ratio is obtained from the financing application information; based on the unlocking conditions and the collateral ratio, a business processing certificate including the collateral ratio is generated; and the business processing certificate including the collateral ratio is sent to the second device.

[0105] It is understandable that the node device can first generate a business processing certificate for the target business based on the unlocking conditions, and send the business processing certificate to the second device. When the second device needs financing from the financing party (i.e., the user corresponding to the third device), the second device can send the business processing certificate and the financing application information to the node device. After receiving the business processing certificate and the financing application information, the node device can destroy the business processing certificate. Furthermore, the mortgage ratio is obtained from the financing application information, the above unlocking conditions and the above mortgage ratio are input into the business processing certificate contract, and based on the business processing certificate contract, a business processing certificate including the above mortgage ratio is generated, and the business processing certificate including the above mortgage ratio is sent to the second device.

[0106] S203: When the processing certification information and the business processing credential sent by the second device are received, the validity of the received business processing credential is verified according to the unlocking condition to obtain a first credential verification result.

[0107] It should be noted that the first credential verification result may include the validity of the received business processing credential and the invalidity of the received business processing credential. The validity of the received business processing credential indicates that the received business processing credential is consistent with the business processing credential of the target business; the invalidity of the received business processing credential indicates that the received business processing credential is inconsistent with the business processing credential of the target business.

[0108] It is understood that when the node device receives the processing certification information and the business processing credential sent by the second device, the node device can obtain the target unlocking condition from the received business processing credential and verify the validity of the received business processing credential based on the target unlocking condition and the unlocking condition. When the received business processing credential is verified to be valid, the node device generates a first credential verification result indicating that the received business processing credential is valid. When the received business processing credential is verified to be invalid, the node device generates a first credential verification result indicating that the received business processing credential is invalid.

[0109] Optionally, determine the degree of match between the unlocking conditions of the resource credential and the unlocking conditions recorded in the received business processing credential; when the degree of match is greater than a matching threshold, determine that the received business processing credential is valid; and generate a first credential verification result reflecting the validity of the received business processing credential.

[0110] It should be noted that the above matching degree may be obtained according to a matching degree algorithm; the above matching degree algorithm may include a KMP algorithm, a BM algorithm, etc. The above matching degree threshold may be set by the node device.

[0111] It will be understood that a matching threshold is set in the node device. Upon receiving the processing certification information and business processing credential sent by the second device, the node device uses a matching algorithm to match the unlocking conditions of the resource credential with the unlocking conditions recorded in the received business processing credential one by one, thereby determining the matching degree between the unlocking conditions of the resource credential and the unlocking conditions recorded in the received business processing credential. The more similar the unlocking conditions of the resource credential are to the unlocking conditions recorded in the received business processing credential, the higher the matching degree; the less similar the unlocking conditions of the resource credential are to the unlocking conditions recorded in the received business processing credential, the lower the matching degree. When the matching degree is greater than the matching threshold, it indicates that the received business processing credential is the business processing credential of the target business; the node device may generate a first credential verification result indicating that the received business processing credential is valid. Alternatively, when the matching degree is less than or equal to the matching threshold, it indicates that the received business processing credential is not the business processing credential of the target business; the node device may generate a first credential verification result indicating that the received business processing credential is not valid. The node device automatically matches the unlocking conditions of the resource voucher with the unlocking conditions recorded in the received business processing voucher to verify the authenticity of the received business processing voucher. This can prevent the resource voucher from being mistakenly unlocked when a forged business processing voucher is received, and the second type of digital resources can be paid to illegal users, thereby improving the security of business processing.

[0112] S204: Determine the actual processing status of the second device for the target service based on the unlocking condition and the processing certification information.

[0113] It should be noted that the unlocking conditions include a time constraint and processing quality requirements. The actual processing status can be either completed or incomplete. When both the time constraint and processing quality requirements are met, the target business's actual processing status is completed. When at least one of the time constraint and processing quality requirements is met, the target business's actual processing status is incomplete.

[0114] It is understandable that the node device can verify whether the second device completes the target business within the restricted completion time and according to the processing quality requirements based on the processing proof information sent by the second device. When the second device processes the target business within the restricted completion time and generates processing proof information that meets the processing quality requirements, the node device can determine that the above-mentioned actual processing status is processing completed. When the second device does not process the target business within the restricted completion time, or the second device does not generate processing proof information that meets the processing quality requirements, the node device can determine that the above-mentioned actual processing status is processing incomplete.

[0115] Optionally, the time of receiving the processing proof information sent by the second device is determined as the actual completion time of the target business; when the actual completion time does not exceed the restricted completion time and the processing proof information meets the processing quality requirements, the actual processing status of the second device for the target business is determined to be processing completed.

[0116] It can be understood that when the node device receives the business processing certificate sent by the second device, it determines the time at this time as the actual completion time of the above-mentioned target business, and compares the actual completion time with the restricted completion time. When the actual completion time does not exceed the restricted completion time, the node device verifies whether the above-mentioned processing proof information meets the processing quality requirements in the unlocking conditions. When the node device verifies that the above-mentioned processing proof information meets the processing quality requirements, it determines that the actual processing status of the above-mentioned second device for the above-mentioned target business is processing completion. For example, when the target business is a cross-border cargo transportation business, the above-mentioned processing quality requirements can be set to obtain the import declaration form of Customs A; when the import declaration form of Customs A exists in the processing proof information, the node device can verify that the above-mentioned processing proof information meets the processing quality requirements.

[0117] S205: Generate a relationship verification result reflecting the relationship between the second device and the unlocking condition according to the first credential verification result and the actual processing status.

[0118] Optionally, the above-mentioned unlocking conditions include the restricted completion time and processing quality requirements of the above-mentioned target business; when the above-mentioned first credential verification result reflects that the above-mentioned received business processing credential is valid and the above-mentioned actual processing status is processing completed, it is determined that the above-mentioned second device meets the above-mentioned unlocking conditions; and a relationship verification result is generated to indicate that the above-mentioned second device meets the above-mentioned unlocking conditions.

[0119] It should be noted that the aforementioned relationship verification result may include a relationship verification result indicating that the second device meets the unlocking conditions, indicating that the received business processing credentials are valid, and the aforementioned actual processing status is completed. The aforementioned relationship verification result may also include a relationship verification result indicating that the second device does not meet the unlocking conditions, indicating that at least one of the following conditions exists: the received business processing credentials are not valid, and the aforementioned actual processing status is not completed.

[0120] It is understood that when the node device determines that the received business processing credential is valid and the actual processing status is completed, it indicates that the second device meets the unlocking condition, and the node device may generate a relationship verification result indicating that the second device meets the unlocking condition. When the node device determines that at least one of the received business processing credential is not valid and the actual processing status is incomplete, it indicates that the second device does not meet the unlocking condition, and the node device may generate a relationship verification result indicating that the second device does not meet the unlocking condition.

[0121] S206. When the relationship verification result indicates that the second device meets the unlocking condition, unlock the resource certificate from the address of the resource locking contract, and control the certificate issuer to pay the second type of digital resources to the second device based on the resource certificate, the received business processing certificate, and the second quantity of the second type of digital resources.

[0122] Optionally, when the relationship verification result indicates that the second device meets the unlocking condition, the resource certificate is unlocked from the address of the resource locking contract, including: when the relationship verification result indicates that the second device meets the unlocking condition, a processing quality approval request for the target business is sent to the first device; the processing quality approval request carries the received business processing certificate and the processing proof information; when the approval message returned by the first device is received, the resource certificate in the resource locking contract address is unlocked through the resource locking contract.

[0123] It should be noted that the processing quality approval request carries the received business processing certificate and processing proof information; the above-mentioned approval information is used to instruct the node device to unlock the resource certificate in the resource locking contract address.

[0124] It is understandable that after the node device verifies the relationship verification result corresponding to the relationship between the second device and the unlocking condition, when the node device determines that the relationship verification result indicates that the second device meets the unlocking condition, the node device can send a processing quality approval request carrying the received business processing credentials and processing proof information to the first device. The first device can approve whether the second device meets the unlocking condition based on the received business processing credentials and processing proof information. When the first device determines that the second device meets the unlocking condition, the first device generates an approval message and sends the approval message to the node device. When the first device determines that the second device does not meet the unlocking condition, the first device can generate an approval failure message and send the approval failure message to the node device. When the first device determines that the second device does not meet the unlocking condition, the first device may not generate a message about approval, that is, the node device cannot receive the message about approval sent by the first device.

[0125] Furthermore, when the node device receives an approval message returned by the first device, the resource certificate in the resource locking contract address may be unlocked. When the node device receives an approval failure message returned by the first device, or the node device does not receive an approval message returned by the first device within a preset time period, the resource certificate in the resource locking contract address may not be unlocked.

[0126] Optionally, based on the above-mentioned resource certificate, the above-mentioned received business processing certificate, and the above-mentioned second quantity of the second category digital resources, the above-mentioned certificate issuer is controlled to pay the second category digital resources to the above-mentioned second device, including: when the above-mentioned received business processing certificate does not include the mortgage ratio, the above-mentioned second quantity of the second category digital resources is transferred from the account address of the above-mentioned certificate issuer to the account address corresponding to the above-mentioned second device; the above-mentioned mortgage ratio is used to instruct the above-mentioned second device to mortgage the above-mentioned third quantity of the second category digital resources to a third device, and the above-mentioned third device is a device that provides financing for the above-mentioned target business to the above-mentioned second device, and the ratio between the above-mentioned third quantity and the above-mentioned second quantity is the above-mentioned mortgage ratio; when the above-mentioned received business processing certificate includes the mortgage ratio, the above-mentioned fourth quantity of the second category digital resources is transferred from the account address of the above-mentioned certificate issuer to the account address corresponding to the above-mentioned second device; the above-mentioned fourth quantity is the difference between the above-mentioned second quantity and the above-mentioned third quantity; destroying the above-mentioned received business processing certificate, and returning the above-mentioned resource certificate to the above-mentioned certificate issuer.

[0127] It should be noted that the above-mentioned pledge ratio reflects the third quantity of the second-category digital resource pledged by the second device to the third device; the ratio between the third quantity and the second quantity is the above-mentioned pledge ratio. For example, if a resource voucher can be redeemed for 100 pieces of the second-category digital resource from the voucher issuer, and the second device pledges 80 pieces of the second-category digital resource to the third device, the above-mentioned pledge ratio may be 80%.

[0128] It should be noted that the third device provides financing for the target business to the second device. The financing provided by the third device to the second device can be obtained based on the third quantity and the discount information. For example, when the second device pledges 80 items of the second-category digital resources to the third device, if the discount information for this pledge is 90%, the third device may send 72 items of the second-category digital resources to the second device.

[0129] It is understandable that after the node device unlocks the resource voucher in the resource locking contract address, the node device will verify the received business processing voucher. When it is verified that the above-mentioned received business processing voucher does not include the mortgage ratio, it indicates that the above-mentioned second device has not mortgaged the business processing voucher to the third device, that is, the resource voucher belongs entirely to the second device; therefore, the node device transfers the above-mentioned second quantity of the second type of digital resources from the account address of the above-mentioned voucher issuer to the account address corresponding to the above-mentioned second device. When it is verified that the above-mentioned received business processing voucher includes the mortgage ratio, it indicates that the above-mentioned second device mortgages the business processing voucher to the third device, that is, the resource voucher partially belongs to the second device; therefore, the node device performs a proportional operation on the second quantity according to the mortgage ratio to obtain the fourth quantity. The node device transfers the fourth quantity of the above-mentioned second type of digital resources from the account address of the above-mentioned voucher issuer to the account address corresponding to the above-mentioned second device.

[0130] Optionally, the above method also includes: sending the business processing certificate including the above mortgage ratio to the above third device; when the business processing certificate sent by the above third device is received, verifying the validity of the business processing certificate sent by the above third device according to the above unlocking condition, and obtaining a second certificate verification result; when the above second certificate verification result indicates that the business processing certificate sent by the above third device is valid, verifying the unlocking status of the above resource certificate; when the unlocking status of the above resource certificate is unlocked, transferring the above third quantity of the second type of digital resources from the account address of the certificate issuer to the account address corresponding to the above third device, and destroying the business processing certificate sent by the above third device.

[0131] It should be noted that the second credential verification result may include that the business processing credential received and sent by the above-mentioned third device is valid, and that the business processing credential received and sent by the above-mentioned third device is not valid. The unlocking status of the resource credential may include unlocked and unlocked. Unlocked may mean that the resource credential has been unlocked, that is, the node device can transfer the above-mentioned third quantity of the second type of digital resources from the account address of the above-mentioned credential issuer to the account address corresponding to the above-mentioned third device based on the resource credential. Unlocked may mean that the resource credential has not been unlocked, that is, the node device cannot transfer the above-mentioned third quantity of the second type of digital resources from the account address of the above-mentioned credential issuer to the account address corresponding to the above-mentioned third device based on the resource credential.

[0132] It is understandable that the node device can send the business processing certificate including the above-mentioned mortgage ratio to the third device. After the node device receives the business processing certificate sent by the above-mentioned third device, the node device can obtain the target unlocking condition from the business processing certificate sent by the above-mentioned third device; match the target unlocking condition with the unlocking condition of the above-mentioned resource certificate one by one, and use the matching algorithm to obtain the target matching degree between the target unlocking condition and the above-mentioned resource certificate. When the target matching degree is greater than the above-mentioned matching degree threshold, the node device determines that the business processing certificate sent by the above-mentioned third device is valid, and obtains a second certificate verification result indicating that the business processing certificate sent by the above-mentioned third device is valid. When the target matching degree is less than or equal to the above-mentioned matching degree threshold, the node device determines that the business processing certificate sent by the above-mentioned third device is not valid, and obtains a second certificate verification result indicating that the business processing certificate sent by the above-mentioned third device is not valid.

[0133] Furthermore, when the second credential verification result indicates that the received business processing credential sent by the third device is valid, the node device may verify the unlocking status of the resource credential. When it is verified that the unlocking status of the resource credential is unlocked, the node device may transfer the third quantity of the second category digital resource from the account address of the credential issuer to the account address corresponding to the third device based on the resource credential. When it is verified that the unlocking status of the resource credential is unlocked, the node device may not transfer the third quantity of the second category digital resource from the account address of the credential issuer to the account address corresponding to the third device based on the resource credential.

[0134] In this application, the node device in the blockchain network can pre-lock the resource certificate of the business entrusting party in the address of the resource locking contract on the blockchain. The resource certificate is used to indicate that after the business service party completes the processing of the target business, the second amount of the second type of digital resources will be paid to the business service party. The resource certificate is purchased by the business entrusting party, which is equivalent to the business entrusting party having frozen (locked) the digital resources required for processing the target business in the address of the resource locking contract in advance. This can avoid the change in the exchange rate between the digital resources used by the business entrusting party and the business service party, causing asset losses to the business entrusting party or the business service party. In addition, the unlocking conditions of the resource certificate are generated according to the processing requirement information of the target business, and the business processing certificate for the target business is generated according to the unlocking conditions, and the business processing certificate is sent to the second device corresponding to the business service party. The business service provider processes the target business and generates processing certification information for the target business. Upon receiving the processing certification information and business processing voucher provided by the business service provider, the business service provider automatically verifies whether the unlocking conditions for the resource voucher are met based on the received business processing voucher and processing certification information. If the unlocking conditions are met, the resource voucher is unlocked, and the second category digital resource is paid to the business service provider based on the resource voucher and the second quantity of the second category digital resource. This allows for automated verification of the business service provider, eliminating the need for human intervention and improving business processing efficiency.

[0135] Further, see Figure 4 , Figure 4 This is a flowchart of a business processing method provided by an embodiment of the present application. Figure 1 The method may be performed by any node device in the blockchain network.

[0136] S301: A first device pays a first quantity of a first-category digital resource to a credential issuer device.

[0137] It should be noted that the first device can use the first type of digital resources to purchase resource certificates from the certificate issuer.

[0138] It is understood that when the first device needs to delegate the target service to the service entrusting party, the first device can convert the first quantity of the first category digital resources available for processing the target service into a resource voucher in advance. Therefore, the first device can transfer the first quantity of the first category digital resources to the account address of the voucher issuer device.

[0139] S302: The credential issuer device sends a minting request for a resource credential to the node device.

[0140] It is understandable that after receiving the first quantity of the first category of digital resources paid by the first device, the certificate issuer device will generate a minting request for the resource certificate and send the minting request to the node device.

[0141] S303: The node device generates a resource credential and sends the resource credential to the first device.

[0142] It is understood that after receiving the minting request, the node device will call the minting function of the resource certificate based on the resource certificate contract to generate a resource certificate; the node device sends the resource certificate to the first device. The resource certificate contract can refer to a smart contract for generating resource certificates.

[0143] S304: The first device sends the resource certificate and processing requirement information to the node device.

[0144] It is understood that the first device receives the resource voucher, indicating that the first quantity of the first category digital resource has been successfully purchased as a resource voucher; based on the resource voucher, it can be exchanged for a second quantity of the second category digital resource from the voucher issuer, where the second quantity is determined based on the first quantity and the current exchange rate between the first category digital resource and the second category digital resource. The first device sends the resource voucher and processing requirement information to the node device.

[0145] S305: Lock the resource certificate to the address of the resource locking contract on the blockchain, and generate unlocking conditions for the resource certificate based on the processing requirement information.

[0146] It is understood that after receiving the resource certificate sent by the first device, the node device can transfer the resource certificate to the resource locking contract and generate unlocking conditions for the resource certificate based on the processing requirement information received from the first device. Therefore, only when the unlocking conditions are met can the node device obtain the second quantity of the second category of digital resources from the certificate issuer device based on the resource certificate.

[0147] S306: Generate a business processing voucher for the target business according to the unlocking condition.

[0148] It is understandable that after receiving the unlocking conditions, the node device will call the casting function of the business processing certificate based on the business processing certificate contract according to the unlocking conditions to generate the business processing certificate of the target business.

[0149] S307: The node device sends the service processing certificate to the first device.

[0150] It is understandable that after the node device generates the service processing credential of the target service, it sends the service processing credential to the first device.

[0151] S308: The first device sends the service processing credential to the second device.

[0152] It is understood that when the first device sends the business processing credential to the second device, it indicates that the first device has delegated the target business to the second device for processing. Specifically, after the first device receives the business processing credential for the target business, the first device can send the business processing credential to the second device. After receiving the business processing credential, the second device can process the target business according to the unlocking conditions recorded in the business processing credential and generate processing proof information for the target business.

[0153] S309: The node device receives the business processing certificate and processing certification information.

[0154] It can be understood that after the second device completes processing the target business and generates processing proof information about the target business, the second device can send the business processing certificate and the processing proof information to the node device, and the node device can receive the business processing certificate and the processing proof information.

[0155] S310: Verify the relationship between the second device and the unlocking condition based on the received business processing credential and processing certification information to obtain a relationship verification result.

[0156] It is understandable that after the node device receives the business processing credentials and processing proof information sent by the second device, it can verify the validity of the received business processing credentials and processing proof information, thereby verifying the relationship between the second device and the unlocking condition and obtaining a relationship verification result.

[0157] S311: When the relationship verification result indicates that the second device meets the unlocking condition, unlock the resource credential from the address of the resource locking contract.

[0158] It can be understood that after the node device determines that the relationship verification result indicates that the second device meets the unlocking condition, it can unlock the resource certificate in the address of the resource locking contract, that is, the node device can transfer the resource certificate out of the resource locking contract address.

[0159] S312: The node device sends the resource certificate to the second device.

[0160] It is understandable that after the node device unlocks the resource certificate from the address of the resource locking contract, it sends the resource certificate to the second device.

[0161] S313: The second device sends the resource certificate to the certificate issuer device.

[0162] It is understood that after receiving the resource voucher, the second device may choose to retain the resource voucher or choose to obtain a second quantity of the second category digital resources based on the resource voucher. When the second device chooses to obtain the second quantity of the second category digital resources based on the resource voucher, the second device may send the resource voucher to the voucher issuer device.

[0163] S314: The certificate issuer device pays the second device a second amount of the second-category digital resource.

[0164] It can be understood that after the certificate issuer device receives the resource certificate, it exchanges the resource certificate for a second quantity of the second category digital resources based on the exchange ratio between the first category digital resources and the second category digital resources when the first device purchases the resource certificate from the certificate issuer, and transfers the second quantity of the second category digital resources to the account address of the second device.

[0165] In this application, the node device in the blockchain network can pre-lock the resource certificate of the business entrusting party in the address of the resource locking contract on the blockchain. The resource certificate is used to indicate that after the business service party completes the processing of the target business, the second amount of the second type of digital resources will be paid to the business service party. The resource certificate is purchased by the business entrusting party, which is equivalent to the business entrusting party having frozen (locked) the digital resources required for processing the target business in the address of the resource locking contract in advance. This can avoid the change in the exchange rate between the digital resources used by the business entrusting party and the business service party, causing asset losses to the business entrusting party or the business service party. In addition, the unlocking conditions of the resource certificate are generated according to the processing requirement information of the target business, and the business processing certificate for the target business is generated according to the unlocking conditions, and the business processing certificate is sent to the second device corresponding to the business service party. The business service provider processes the target business and generates processing certification information for the target business. Upon receiving the processing certification information and business processing voucher provided by the business service provider, the business service provider automatically verifies whether the unlocking conditions for the resource voucher are met based on the received business processing voucher and processing certification information. If the unlocking conditions are met, the resource voucher is unlocked, and the second category digital resource is paid to the business service provider based on the resource voucher and the second quantity of the second category digital resource. This allows for automated verification of the business service provider, eliminating the need for human intervention and improving business processing efficiency.

[0166] See Figure 5 , Figure 5 This is a schematic diagram of the structure of a business processing device provided in an embodiment of the present application. Figure 5 As shown, the service processing device may include:

[0167] A locking module 511 is configured to obtain processing requirement information for a target business to be processed by a first device, lock a resource voucher of the first device to the address of a resource locking contract on a blockchain, and generate unlocking conditions for the resource voucher based on the processing requirement information; the resource voucher is purchased by the first device from a voucher issuer using a first quantity of a first-category digital resource, and the resource voucher is used to pay a second quantity of a second-category digital resource to the second device after the second device completes the target business, where the second quantity is determined based on the first quantity and a current exchange rate between the first-category digital resource and the second-category digital resource;

[0168] A generating module 512 is configured to generate a business processing credential for the target business based on the unlocking condition, and send the business processing credential for the target business to the second device; the business processing credential for the target business is used to instruct the second device to process the target business and generate processing certification information for the target business;

[0169] a verification module 513 configured to, upon receiving the processing certification information and the business processing credential sent by the second device, verify the relationship between the second device and the unlocking condition based on the received business processing credential and the processing certification information, and obtain a relationship verification result;

[0170] The unlocking module 514 is used to unlock the resource certificate from the address of the resource locking contract when the relationship verification result indicates that the second device meets the unlocking condition, and control the certificate issuer to pay the second type of digital resources to the second device based on the resource certificate, the received business processing certificate, and the second quantity of the second type of digital resources.

[0171] In a possible implementation, the verification module 513 is further configured to perform the following operations:

[0172] Verify the validity of the received business processing credential according to the unlocking condition to obtain a first credential verification result;

[0173] determining, based on the unlocking condition and the processing certification information, an actual processing status of the second device for the target service;

[0174] A relationship verification result reflecting a relationship between the second device and the unlocking condition is generated according to the first credential verification result and the actual processing status.

[0175] In a possible implementation, the verification module 513 is further configured to perform the following operations:

[0176] Determining a degree of match between the unlocking condition of the resource credential and the unlocking condition recorded in the received business processing credential;

[0177] When the matching degree is greater than the matching degree threshold, determining that the received business processing certificate is valid;

[0178] A first credential verification result is generated to reflect that the received business processing credential is valid.

[0179] In a possible implementation, the verification module 513 is further configured to perform the following operations:

[0180] Determining the time at which the processing certification information sent by the second device is received as the actual completion time of the target business;

[0181] When the actual completion time does not exceed the restricted completion time and the processing certification information meets the processing quality requirement, it is determined that the actual processing status of the target business by the second device is processing completed.

[0182] In a possible implementation, the verification module 513 is further configured to perform the following operations:

[0183] When the first credential verification result indicates that the received business processing credential is valid and the actual processing status is processing completed, determining that the second device meets the unlocking condition;

[0184] A relationship verification result is generated to indicate that the second device satisfies the unlocking condition.

[0185] In a possible implementation, the unlocking module 514 is further configured to perform the following operations:

[0186] When the relationship verification result indicates that the second device meets the unlocking condition, sending a processing quality approval request for the target service to the first device; the processing quality approval request carries the received service processing voucher and the processing certification information;

[0187] When the approval message returned by the first device is received, the resource certificate in the resource locking contract address is unlocked through the resource locking contract.

[0188] In a possible implementation, the unlocking module 514 is further configured to perform the following operations:

[0201] In the embodiments of the present application, the term "module" or "unit" refers to a computer program or a part of a computer program that has a predetermined function and works together with other related parts to achieve a predetermined goal, and can be implemented in whole or in part by using software, hardware (such as processing circuits or memories) or a combination thereof. Similarly, a processor (or multiple processors or memories) can be used to implement one or more modules or units. In addition, each module or unit can be part of an overall module or unit that includes the function of the module or unit.

[0202] In this application, the node device in the blockchain network can pre-lock the resource certificate of the business entrusting party in the address of the resource locking contract on the blockchain. The resource certificate is used to indicate that after the business service party completes the processing of the target business, the second amount of the second type of digital resources will be paid to the business service party. The resource certificate is purchased by the business entrusting party, which is equivalent to the business entrusting party having frozen (locked) the digital resources required for processing the target business in the address of the resource locking contract in advance. This can avoid the change in the exchange rate between the digital resources used by the business entrusting party and the business service party, causing asset losses to the business entrusting party or the business service party. In addition, the unlocking conditions of the resource certificate are generated according to the processing requirement information of the target business, and the business processing certificate for the target business is generated according to the unlocking conditions, and the business processing certificate is sent to the second device corresponding to the business service party. The business service provider processes the target business and generates processing certification information for the target business. Upon receiving the processing certification information and business processing voucher provided by the business service provider, the business service provider automatically verifies whether the unlocking conditions for the resource voucher are met based on the received business processing voucher and processing certification information. If the unlocking conditions are met, the resource voucher is unlocked, and the second category digital resource is paid to the business service provider based on the resource voucher and the second quantity of the second category digital resource. This allows for automated verification of the business service provider, eliminating the need for human intervention and improving business processing efficiency.
