Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In order to facilitate understanding of the technical processes of the embodiments of the present application, some terms referred to in the embodiments of the present application are explained below:

block chain (Block chain): the method is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain is essentially a decentralized database, which is a string of data blocks associated by cryptography, each data block containing information about a network transaction for verifying the validity (anti-counterfeiting) of the information and generating the next block, each block containing a timestamp and a link to the previous block. In a narrow sense, a blockchain is a distributed ledger of data blocks assembled in a sequential manner into a chain data structure in chronological order and cryptographically secured as non-falsifiable and non-forgeable, i.e. the data in the blockchain will be irreversible once recorded.

Consensus mechanism (Consensus mechanism): the block chain system is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes. In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of special nodes, and if a plurality of nodes with irrelevant benefits can achieve consensus on a transaction, all the nodes in the system can also achieve consensus on the transaction.

Smart contract (Smart contract): is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Each node in the blockchain system can automatically execute a contract program according to a specific condition, can operate data stored in the chain, and is an important way for a user to interact with the blockchain and realize business logic by using the blockchain. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts, which allows for trusted transactions that are traceable and irreversible without third parties.

The present embodiment provides a blockchain system 100 implemented based on blockchain technology, and a system architecture of the blockchain system is described below.

Fig. 1 is a schematic diagram of a blockchain system 100 according to an embodiment of the present disclosure, and referring to fig. 1, the blockchain system 100 includes a plurality of node apparatuses 101, and each node apparatus 101 may belong to different organizations. For example, at least one node device 101 belongs to a bank, and at least one node device 101 belongs to a regulatory body, and of course, it may also be included that at least one node device 101 belongs to a target body that needs to perform resource aggregation. In addition, the blockchain system 100 may further include at least one client, that is, at least one node device 101 may have the client installed and operated therein, and the client may be a client of a target application for providing a resource aggregation function, for example, a client of a financial application, and the like.

The node device 101 may be any form of computing device in a network, such as a server, a host, a user terminal, etc. The node apparatus 101 and the node apparatus 101 can share data therebetween. Among them, the node devices 101 may establish a P2P network based on a Peer-To-Peer (P2P) protocol. The P2P Protocol is an application layer Protocol that runs on top of the Transmission Control Protocol (TCP) Protocol.

Each node apparatus 101 receives input information during normal operation, and maintains the shared data in the blockchain system 100 based on the received input information, that is, maintains the blockchain in the blockchain system 100. In order to ensure information intercommunication in the blockchain system 100, there may be an information connection between each node apparatus 101 in the blockchain system 100, and the node apparatuses 101 perform information transmission through the information connection. For example, when any node device 101 in the blockchain system 100 receives input information, other node devices 101 in the blockchain system 100 may also obtain the input information and store the input information as data in shared data, so that the data stored on all node devices 101 in the blockchain system 100 are consistent.

The technical scheme provided by the embodiment of the application can be combined with multiple fields and multiple application scenes, for example, the technical scheme can be combined with a supply chain, and when all organizations in the supply chain carry out resource aggregation, all organizations, banks, warranty companies, supervision agencies, bill qualification management platforms and the like in the supply chain can construct a block chain system. The blockchain system may be a federation chain system, see fig. 2, and fig. 2 is a schematic diagram of a federation chain system provided in the embodiment of the present application, and the federation chain system 201 may include node devices 202 of various enterprises in a supply chain, node devices 203 of banks, node devices 204 of a supervision platform, node devices 205 of a bill qualification management platform, and the like. Of course, the blockchain system may also be implemented in other forms, which is not limited in the embodiments of the present application. And each node device in the blockchain system performs data storage, data sharing and data verification through the blockchain. For example, when a target mechanism with resource aggregation requirement applies for resource aggregation, the data stored in the block chain is used as an application certificate, so that the application material does not need to be prepared, and the efficiency of a material preparation stage is improved; in the process of applying for resource aggregation, the application voucher is shared to resource holding organizations such as banks and warranty companies through a block chain, materials do not need to be submitted offline, and the safety of data is ensured; the resource holding mechanism verifies the qualification of the target mechanism based on the data in the block chain, and the difficulty of data verification can be effectively reduced because the data stored in the block chain cannot be deleted and tampered.

Fig. 3 is a timing diagram of a resource aggregation method based on a block chain according to an embodiment of the present application. The method can be applied to the above implementation environment, and the resource aggregation method is briefly described below with reference to fig. 3:

301. the first node equipment responds to a data acquisition instruction of a target organization, and acquires target qualification certification data indicated by a resource aggregation type from qualification certification data of the target organization stored in a block chain based on an organization identifier and the resource aggregation type of the target organization carried by the data acquisition instruction.

The first node device is deployed with a bill qualification management platform, and the bill qualification management platform is used for managing bill data, voucher data and the like. The target mechanism may be any mechanism in the supply chain.

In a possible implementation manner, a client of the ticket qualification management platform is installed and operated on the node device corresponding to the target organization, and the target organization can log in the client when applying for resource aggregation, select a resource aggregation type through the client, and send a data acquisition instruction to the first node device. The first node device executes a data acquisition step from a blockchain of a blockchain system in response to the data acquisition instruction. The block chain stores qualification certification data of a plurality of organizations, including bill data, voucher data, organization operation data and the like. And the first node equipment acquires target qualification certification data required by the target organization in the resource aggregation process from the block chain based on the organization identification and the resource aggregation type carried in the data acquisition instruction. Wherein an institution identification is used to uniquely identify an institution, optionally the institution identification is represented as an account address of the institution in the blockchain system, etc.

In the embodiment of the application, the first node device automatically acquires the target qualification certification data from the block chain system based on the resource aggregation type without inputting data by a user or sorting the data by the user according to the resource aggregation type, so that the data preparation stage is standardized and normalized, the time consumption of the data preparation stage is reduced, and data loss is avoided.

302. The first node device generates a resource aggregation request in response to the data submission instruction, the resource aggregation request including the institution identification, the resource aggregation type, and the target qualification data.

In a possible implementation manner, the first node device sends a prompt message of data acquisition completion to the node device of the target organization after data acquisition is completed, the target organization sends a data submission instruction to the first node device through the client after confirming that the acquired target qualification certification data is correct, and the first node device generates a resource aggregation request based on the organization identifier of the target organization, the resource aggregation type and the target qualification certification data. In a possible implementation manner, the first node device may further perform desensitization processing on the acquired target qualification certification data, and generate a resource aggregation request based on the desensitized target qualification certification data, so as to ensure data security of the target organization.

303. The first node device constructs a target block based on the resource aggregation request and a block with a highest block height in the blockchain, and stores the target block to the blockchain in response to a consensus that the target block passes through the blockchain system.

In one possible implementation, the first node device broadcasts the resource aggregation request to each target node device of the blockchain system, and each target node device may perform the step of target block construction. The target node device is a node device with an accounting function in the block chain system. In this embodiment, taking the example that the first node device constructs the target block as an example, the first node device stores the resource aggregation request into a memory pool, where the memory pool is used to store data that is not added to the block chain. The first node device obtains a hash value of a block with the highest block height in the block chain, and constructs a target block based on the data in the memory pool and the hash value of the block, wherein the target block comprises the resource aggregation request. For example, after the first node device receives the input information, the update timestamp may be updated to the time when the input information is received, different random numbers are tried, and the feature value calculation is performed multiple times, so that the calculated feature value satisfies the following formula (1):

SHA256(SHA256(version+prev_hash+meikle_root+ntime+nbits+x))<TARGET (1)

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; the prev _ hash is a block head characteristic value of a parent block of the current block, namely a hash value of a block with the highest block height; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a threshold value of the characteristic value, and the threshold value of the characteristic value is determined according to nbits.

When the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and a block header and a block main body are generated to obtain a target block. In response to the target block generation, the first node device broadcasts the target block to at least two other target node devices of the blockchain system based on the node identifiers of the other target node devices in the blockchain system, and each target node device verifies the target block; in response to the target node device verifying the target block, i.e., agreeing, the target block is added to the end of the blockchain.

It should be noted that the above description of the method for storing the resource aggregation request to the block chain is only an exemplary description, and the embodiment of the present application does not limit which method is specifically used to store the resource aggregation request to the block chain. In the embodiment of the application, the resource aggregation request is stored in the blockchain, and the blockchain system is applied to share data, so that data information among node devices is prevented from being broken and unequal, and data consistency among the node devices is ensured.

304. And the first node equipment sends prompt information for finishing data storage to the second node equipment, wherein the prompt information carries the storage position information of the resource aggregation request in the block chain.

The second node device is a node device corresponding to a resource holding organization such as a bank, a warranty organization and the like.

In a possible implementation manner, after the resource aggregation request is completely stored in the blockchain, the first node device needs to send a prompt message indicating that data storage is completed to the second node device, so as to prompt the second node device to verify the resource aggregation request of the target institution.

305. And the second node equipment acquires the resource aggregation request from the block chain based on the storage position information, and matches the target qualification certification data in the resource aggregation request with the aggregation condition corresponding to the resource aggregation type.

Optionally, the storage location information includes location information of the target block in a block chain and location information of the resource aggregation request in the target block.

In one possible implementation manner, the second node device obtains the resource aggregation request from the target block of the block chain based on the storage location information in the hint information. The second node device obtains the target qualification certification data and the resource aggregation type in the resource aggregation request, and matches the target qualification certification data with the aggregation condition corresponding to the resource aggregation type. The aggregation condition and the corresponding relationship between the resource aggregation type and the aggregation condition may be set by a developer, which is not limited in this application.

It should be noted that the above description of the method for verifying the resource aggregation request by the second node device is only an exemplary description of a verification method, and the embodiment of the present application does not limit which method is specifically adopted by the second node device to verify the resource aggregation request. In the embodiment of the application, because the data stored in the block chain cannot be deleted and tampered, the authenticity and the validity of the acquired data can be ensured, and therefore, the difficulty of data verification can be reduced by performing resource aggregation request verification based on the data in the block chain.

306. And the second node equipment responds to the successful matching and carries out resource transfer.

In a possible implementation manner, if the target qualification certification data is successfully matched with the aggregation condition corresponding to the resource aggregation type, the second node device transfers the resource to the target institution based on the account address of the target institution, and sends a prompt message of successful resource aggregation; and if the target qualification certification data is successfully matched with the aggregation condition corresponding to the resource aggregation type, the second node equipment sends prompt information of resource aggregation failure to the target mechanism to prompt the target mechanism to resubmit the qualification certification data.

According to the technical scheme provided by the embodiment of the application, the first node equipment acquires the target qualification certification data from the block chain based on the resource aggregation type of the target mechanism, the target mechanism does not need to prepare the data by itself and submit the data offline, and the time consumption of a data preparation stage is reduced; the first node device stores the resource aggregation request containing the target qualification certification data to the block chain, and the second node device acquires the target qualification certification data from the block chain for verification. By applying the scheme, the efficiency and the safety of the resource aggregation process are improved from two stages of data preparation and data verification.

In the embodiment of the present application, data interaction is performed between node devices corresponding to a target organization, node devices corresponding to resource holding organizations such as banks, node devices corresponding to a monitoring organization, and a bill qualification management platform based on a blockchain system, so that safety and efficiency of a resource aggregation process can be ensured. For example, fig. 4 is a data interaction architecture diagram provided in an embodiment of the present application, as shown in fig. 4, a business processing system and a financial system of a target organization 401, a core business system and a resource transfer business system of a bank 402, and a monitoring organization 403 for providing mid-registration, invoice data inspection, electronic subscription, real name authentication, and business networking verification functions may perform data interaction with a bill qualification management platform 404 in a blockchain system, and perform each step in a resource aggregation process based on bill data management, a certificate data management function, and data stored in a blockchain provided by the bill qualification management platform 404, so as to improve efficiency and security of the resource aggregation process. The resource aggregation process will be specifically described below with reference to fig. 5. Fig. 5 is a timing diagram of a resource aggregation method based on a block chain according to an embodiment of the present application, where the method may be applied in the implementation environment shown in fig. 1. Referring to fig. 5, this embodiment includes the steps of:

For example, the fourth node device may display a resource aggregation type selection interface, and the fourth node device may obtain the selected resource aggregation type in the resource aggregation type selection interface, and generate the data obtaining instruction. Wherein, the data acquisition instruction carries the mechanism identifier of the target mechanism and the resource aggregation type. And the first node equipment sends the data acquisition instruction to a background server of the bill management platform, namely the first node equipment.

It should be noted that the above description of the data acquisition instruction generation method is only an exemplary description, and the embodiment of the present application is not limited to which method is specifically adopted by the node device corresponding to the target mechanism, that is, the device in the fourth section, to generate the data acquisition instruction.

502. The first node device acquires target qualification data from a blockchain of the blockchain system in response to the data acquisition instruction.

The different resource aggregation types correspond to different data types, and the correspondence between the resource aggregation types and the data types may be set by a developer, which is not limited in the embodiment of the present application.

In one possible implementation, the data acquisition process may be implemented based on a smart contract. For example, the data acquisition instruction may trigger a first intelligent contract in the blockchain system, the contract content of the first intelligent contract comprising acquiring data from the blockchain based on the organization identification of the target organization and the resource aggregation type. After the first intelligent contract is triggered, the steps appointed in the contract content can be executed, and the target qualification certification data required by the target mechanism in the resource aggregation process is obtained from the block chain.

It should be noted that the above description of the method for acquiring target qualification data is only an exemplary description, and the embodiment of the present application is not limited to which method is specifically adopted by the first node device to acquire the target qualification data.

503. The first node device sends the target qualification data to the fourth node device.

In a possible implementation manner, after the data is acquired, the first node device may send the target qualification data to a node device of the target organization, that is, a fourth node device, where the node device of the target organization displays the target qualification data on a data viewing interface, so that a user can check the target qualification data.

504. The first node device generates a resource aggregation request in response to a data submission instruction of the target qualification data by the fourth node device.

In a possible implementation manner, the data viewing interface may display a submission control, and when the node device corresponding to the target organization, that is, the fourth node device detects a trigger operation on the submission control, a data submission instruction is generated. The data submission instruction may carry an organization identifier of the target organization, and the triggering operation may be a click operation, a long-time press operation, or the like, which is not limited in the embodiment of the present application. It should be noted that the above description of the data submission instruction generation method is only an exemplary description, and the embodiment of the present application does not limit which method is specifically used to generate the data submission instruction. And the fourth node equipment sends the data submission instruction to the first node equipment, and the first node equipment responds to the data submission instruction and generates a resource aggregation request. Wherein the resource aggregation request includes the institution identification, the resource aggregation type, and target qualification data of the target institution.

505. The first node device stores the resource aggregation request to the block chain based on a consensus mechanism.

In this embodiment of the application, the first node device needs to store the resource aggregation request to the blockchain to ensure that data is not lost or tampered, and synchronize the resource sharing request to other node devices in the blockchain system through the blockchain, which is also convenient for the other node devices to perform data auditing.

It should be noted that the process of storing the resource aggregation request to the block chain is the same as that in step 303, and is not described herein again.

506. And the first node equipment responds to the resource aggregation request and stores the resource aggregation request into the block chain, and sends prompt information of data storage completion to the second node equipment and the third node equipment.

The second node equipment is corresponding to a resource holding organization such as a bank, and a user of the second node equipment determines the resource aggregation qualification of the target organization; the third node device is a node device corresponding to the supervision organization, and the third node device is used for verifying the resource aggregation request; the hint information carries the storage location information of the resource aggregation request in the block chain.

In this embodiment of the application, after the data storage is completed, the first node device needs to send a prompt message indicating that the data storage is completed to the node devices corresponding to the mechanism for performing data verification in the block chain system, that is, the second node device and the third node device, so that the node devices can verify the data in time, time consumed in the data verification stage is shortened, and the efficiency of resource aggregation is improved.

507. And the second node equipment responds to the prompt message, acquires the resource aggregation request from the block chain, and determines the resource aggregation qualification of the target institution based on the resource aggregation request.

In this embodiment, the second node device obtains the resource aggregation request from the block chain based on the storage location information, for example, based on location information of a target block storing the resource aggregation request in the block chain and location information of the resource aggregation request in the target block, and matches the target qualification certification data in the resource aggregation request with the aggregation condition corresponding to the resource aggregation type. In a possible implementation manner, a resource set type may correspond to at least one data type, where the data types are data types of data that a target entity needs to provide when performing resource aggregation, and each data type may correspond to an aggregation condition, where the aggregation condition is used to indicate a data value condition corresponding to a certain data type. For example, the data type is a product delivery record, and the corresponding aggregation condition may be set as a product delivery number of the target institution in a certain time period, and the like, which is not limited in the embodiment of the present application. The second node device may match data of each data type in the target qualification data with the corresponding data aggregation condition.

In a possible implementation manner, if, in the target qualification certification data, the data of each data type is successfully matched with the corresponding aggregation condition, or is successfully matched with aggregation conditions exceeding a target number, the first node device determines that the target qualification certification data is successfully matched with the resource aggregation type, that is, determines that the target institution has resource aggregation qualification; otherwise, the matching fails, and the target mechanism does not have the resource aggregation qualification.

In one possible implementation, the data matching and resource aggregation qualification determination process may be implemented based on an intelligent contract. For example, the hint information may trigger a second intelligent contract in the blockchain system, the contract content of the second intelligent contract including matching the target qualification data with the aggregation condition corresponding to the resource aggregation type. After the second intelligent contract is triggered, the steps appointed in the contract content can be executed to obtain a matching result and determine the resource aggregation qualification of the target mechanism.

In a possible implementation manner, the second node device may further store the matching result to the blockchain of the blockchain system based on a consensus mechanism, so as to avoid data loss and tampering and facilitate data verification. It should be noted that the process of storing the matching result in the block chain is the same as the process of storing the resource aggregation request in the block chain in step 303, and details are not described herein.

508. And the third node equipment responds to the prompt message, acquires the resource aggregation request from the block chain and verifies the resource aggregation request.

In this embodiment, the third node device may obtain the resource aggregation request from the block chain based on the storage location information in the prompt information, and verify the target qualification data in the resource aggregation request. In one possible implementation, the third node device may verify data status information of the target qualification data. The data state information includes two states of participating in resource aggregation and not participating in resource aggregation, the data state information is stored in a block chain, and the data state information of one data carries the data identifier of the one data. Taking data state information verification of a target qualification data as an example, the third node device obtains the data state information of the target qualification data from the block chain based on the data identifier of the target qualification data; determining that the target qualification certification data passes verification in response to the data state information not participating in resource aggregation; and in response to the data state information being that the resource aggregation is participated, determining that the target qualification data verification fails.

In one possible implementation, the data validation process described above may be implemented based on smart contracts. For example, the hint information may trigger a third intelligent contract in the blockchain system, the contract content of the third intelligent contract including verifying the data state of the target qualification data. After the third intelligent contract is triggered, the steps appointed in the contract content can be executed, and the data state information is obtained from the block chain for data state verification.

It should be noted that the above description of the method for verifying the resource aggregation request by the third node device is only an exemplary description, and the third node device may also verify the resource aggregation request by other methods, which is not limited in this embodiment of the present application. In the embodiment of the present application, the third node device performs verification based on the data state information stored in the block chain, so that a situation that one qualification data participates in multiple resource aggregation can be avoided, and the security and normalization of resource aggregation are ensured.

In one possible implementation manner, the third node device sets the data state information of the target qualification data to be a participated resource aggregation state in response to the target qualification data passing verification, and stores the data state information of the target qualification data to the blockchain of the blockchain system based on a consensus mechanism. Of course, the third node device may also store the verification result of the data status information to the block chain for data verification. It should be noted that the process of storing the resource aggregation state and the verification result in the block chain is the same as the process of storing the resource aggregation request in the block chain in step 303, and is not described herein again.

509. The third node device sends the verification result to the second node device.

In this embodiment of the present application, after the data verification is completed, the third node device sends a verification result to the second node device, and the second node device may perform subsequent steps based on the verification result. For example, if the verification result is that the verification passes, the second node device may continue to perform step 410; if the verification result is that the verification fails, the second node device does not need to perform the step of resource transfer, and the second node device may send a prompt message of failure of resource aggregation to the node device corresponding to the target mechanism, that is, the fourth node device, so as to prompt the target mechanism to re-trigger the process of applying for resource aggregation.

510. And the second node equipment carries out resource transfer in response to the successful matching and the verification result is that the verification is passed.

In this embodiment, the second node device determines that the target qualification data is successfully matched with the aggregation condition, that is, it is determined that the target institution has resource aggregation qualification, and when the data verification result of the third node device is verification pass, resource transfer may be performed based on the account address of the target institution. In a possible implementation manner, when the second node device performs data matching, the resource aggregation qualification level of the target institution may be determined based on a matching condition of the target qualification data and the aggregation condition. For example, if the target qualification data is successfully matched with each resource aggregation condition, the resource aggregation qualification level of the target organization is level a, and if the target qualification data is successfully matched with aggregation conditions exceeding the target number, the resource aggregation qualification level is level B. The different resource aggregation qualification levels correspond to different resource aggregation limits, and the second node device can perform resource transfer based on the resource aggregation qualification level of the target institution and the account address of the target institution. The target number, the resource aggregation qualification level, and the resource aggregation amount may be set by a developer, which is not limited in the embodiment of the present application.

It should be noted that the above description of the resource transfer method is only an exemplary description, and the embodiment of the present application does not limit which method is specifically adopted for resource transfer.
