To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Fig. 1 schematically shows a system architecture of a method for partition chain-based inventory data processing applicable to an embodiment of the present disclosure.
Referring to fig. 1, a system architecture 100 suitable for the method for partition chain based inventory data processing according to the embodiment of the present disclosure includes: the user equipment terminal 110, the user node 120, the bank node 130 and the bank equipment terminal 140, where the user node 120 and the bank node 130 form a blockchain system (also can be understood as a blockchain network), and in the blockchain system, the nodes implement processing of clearing data by loading and executing the intelligent contract data conversion protocol 101.
The user device side 110 is an electronic device side of an enterprise user, and may also be an electronic device side of an individual user. The electronic equipment end can be a terminal device or a server, the user equipment end can be provided with applications such as a financial system or a clearing system or provide data service support for the applications, and clearing data are obtained by collecting and sorting information such as transaction data and accounts.
User node 120 is a node registered by an enterprise user or an individual user in the blockchain system, and the user node can perform data transmission and data consensus, blockchain ledger recording and synchronization, and the like with other nodes in the blockchain system, such as bank nodes, based on a blockchain P2P (peer-to-peer) network.
The banking device side 140 may be an electronic device side of a financial institution for performing a payment operation of the liquidation data, and may be a server or a terminal of each bank, for example.
The bank node 130 is a node registered in the blockchain system by a financial institution for performing a payment operation of the liquidation data, and the bank node can perform data transmission and data consensus, blockchain ledger recording and synchronization, and the like with a user node in the blockchain based on a blockchain P2P (peer-to-peer) network. In fig. 1, two bank nodes are an X bank node and a Y bank node, respectively, as an example, in an embodiment of the present disclosure, the bank nodes of the blockchain system may be one or more, and a financial institution processing the liquidation data may join the blockchain system according to its own needs.
In embodiments of the present disclosure, the clearing data refers to a set of payment data formed by supply chain financial receivables redemption.
For example, a set of liquidation data generated by a financial system or a liquidation system in the user equipment terminal 110 is as follows:
business a accounts payable 10000 to business B, for example the liquidation data needs to be processed by X bank,
the accounts payable 5000 of the B enterprise to the C enterprise, for example, the liquidation data needs to be processed by the Y bank,
enterprise C accounts payable 2000 to enterprise D, for example, the liquidation data needs to be processed by bank Y.
The user equipment terminal 110 sends the clearing data packet containing the group of clearing data to the user node 120, and the user node 120 loads and carries out data conversion loading on the clearing data packet based on the intelligent contract data conversion protocol 101 to obtain encrypted target clearing protocol data which is suitable for the entry form of bank clearing data; the target liquidation protocol data is synchronized to the bank nodes 130 in the blockchain system. The bank node 130 receives the target liquidation agreement data synchronized by the user node 120; loading and carrying out analysis and verification processing on the target clearing protocol data based on the intelligent contract data conversion protocol 101; and sending the analyzed and verified target liquidation data to the banking equipment end 140 corresponding to the banking node. Therefore, the bank equipment terminal can carry out transaction payment processing according to the clearing data to obtain a processing result of the clearing data.
The life cycle state of the intelligent contract data conversion protocol is synchronously updated and continued between the user node and the bank node. For example, in the process of processing a certain group of liquidation data packets based on the intelligent contract data conversion protocol, when a certain execution condition of a user node or a bank node triggers a contract termination condition, the user node or the bank node correspondingly terminates the execution of the intelligent contract data conversion protocol, updates a contract state corresponding to the intelligent contract data conversion protocol to be an end state, and synchronizes the contract state to other nodes in the block chain system. In one embodiment, the user node performs data conversion loading on the liquidity data packet based on an intelligent contract data conversion protocol, and a contract state corresponding to the intelligent contract data conversion protocol is in an initialization state; after receiving the target clearing data, the bank node loads and analyzes and checks the target clearing protocol data based on the intelligent contract data conversion protocol, and at the moment, the contract state corresponding to the intelligent contract data conversion protocol is in an initialized analysis state (the continuation of the contract state is realized); after the bank node sends the target clearing data to the bank equipment end corresponding to the bank node, the bank node waits for the processing progress state or the processing result of the target clearing data fed back by the bank equipment end; and after the bank node receives the processing result of the target clearing data, updating the contract state of the intelligent contract data conversion protocol to be the end state, and synchronizing the contract state to the user node (realizing synchronous updating of the contract state).
Specific embodiments are described below with reference to the accompanying drawings.
A first exemplary embodiment of the present disclosure provides a method for processing liquidation data based on a blockchain, where the method of this embodiment is applied to the user node 120 in the system architecture 100, and the user node 120 and at least one bank node 130 form a blockchain system.
Fig. 2 schematically shows a flowchart of a method for partition chain based inventory data processing according to an embodiment of the present disclosure.
Referring to fig. 2, a method for processing liquidation data based on a block chain according to an embodiment of the present disclosure includes the following steps: s210, S220 and S230.
In step S210, an inventory data packet to be processed is received, where the inventory data packet has inventory data that needs to be processed by one or more target bank nodes in a targeted manner.
In one implementation scenario, the received credit packets may be credit packets of different representations. For example, different enterprise users each have an independent set of expression form of score clearing data, the enterprise users upload the score clearing data to the user node through the enterprise user equipment, and accordingly, the user node receives the score clearing data packet to be processed, and performs data conversion loading on the score clearing data packet based on the intelligent contract data conversion protocol by executing the subsequent step S220.
For example, the score data included in the score packet is in the following form: { Enterprise A → Enterprise B, 10000, Bank X; business B → business C, 5000, bank Y; c corporation → D corporation, 2000, Y Bank }. Or, some of the sorting packets are in the following form: { X Bank: enterprise a, enterprise B, 10000; and (5) bank Y: enterprise B, enterprise C, 5000; and bank Y: enterprise C, enterprise D, 2000 }. In this embodiment, the target bank nodes are an X bank node and a Y bank node.
In step S220, the data conversion and loading are performed on the clearing data packet based on the intelligent contract data conversion protocol, so as to obtain encrypted target clearing protocol data adapted to the bank clearing data entry form.
Because different banks respectively have a set of system of oneself to stipulate the parameter form, carry out data conversion loading through intelligent contract data conversion agreement to the packet of clearing, can unify each clearing data of the packet of clearing the same group and load and convert the adaptation to different bank equipment ends.
The intelligent contract is a section of code written on a block chain, a section of event triggers terms in the contract, the content of the contract automatically executed by the code (executed when the condition is met), parameters, triggering conditions and the like are correspondingly designed.
The life cycle state of the intelligent contract data conversion protocol is updated and continued synchronously between the user node and the bank node, and specific description of the life cycle state of the intelligent contract data conversion protocol in the system framework can be referred to, which is not described herein again.
The intelligent contract data conversion protocol is used for loading various input forms of score clearing data packets into a unified entry-parameter form and performing conversion processing to obtain encrypted target score clearing protocol data which is suitable for the entry-parameter form of the bank score clearing data.
For example, based on the intelligent contract data conversion protocol, the liquidation data packets in the two examples are loaded into a unified entry form: { from: A, to: B, atmospheric: 10000, Code X ；from:B，to:C，amount:5000，Code Y ；from:C，to:D，amount:2000，Code Y }. That is, the unified reference form is<from，to，amount，code>. After the entry of the liquidation data in the unified form is further converted, encrypted target liquidation protocol data in the entry form suitable for the X bank and the Y bank is obtained, for example, the entry form of the X bank is as follows: { payee business name and abbreviation, payer business name and abbreviation, transaction amount }, entry form of bank Y: { payer Enterprise organization codePayee enterprise organization code, payment amount }; the target liquidation protocol data is in encrypted form and contains the following: { payee business name and abbreviation: business name and abbreviation, payer business name and abbreviation: business name and abbreviation, transaction amount: 10000; payer enterprise organization code: b enterprise organization code, payee enterprise organization code: c enterprise organization code, payment amount: 5000; payer enterprise organization code: enterprise organization code, payee enterprise organization code: enterprise organization code, payment amount: 2000}.
When the intelligent contract data conversion protocol initializes the loading parameters, the score clearing data general template can be utilized to load the score clearing data packet into a unified entry form.
Each bank has a bank clearing data template corresponding to each bank, and the bank clearing data template has a specification setting of a reference form.

Fig. 3 schematically shows a detailed implementation flowchart of step S220 of the embodiment of the present disclosure.
According to an embodiment of the present disclosure, as shown in fig. 3, in the step S220, loading and performing data conversion loading on the liquidation data packet based on an intelligent contract data conversion protocol to obtain encrypted target liquidation protocol data adapted to a banking liquidation data entry form, includes the following steps: s310, S320, S330a, and S340 a.
In step S310, an intelligent contract data conversion protocol is loaded, and the liquidation data is used as an input parameter of the intelligent contract data conversion protocol and is initialized to obtain a contract general parameter related to the liquidation data.
According to an embodiment of the present disclosure, the contract general parameters include: a public parameter key factor, a contract state, an initialization public parameter, an initialization clearing parameter, and a signature parameter.
The public parameter key factor is a parameter generated by performing a first calculation according to the node information (e.g., a bank node address) of the target bank node. The first calculation mode is an appointed calculation mode between the user node and the target bank node. For example, if the first calculation is a hash calculation, the calculation formula of the public parameter key factor pri1 is expressed as: pri 1= hash (B1), B1 represents the banking node address of the target banking node.
The contract state is used for representing the execution state of the intelligent contract data conversion protocol, and is an initialization state in the stage of entering into initialization processing. For example, representing the contract state as status1, the contract state as initialized state may be represented as: status1= init.
The initialized public parameters comprise a contract address and a bank node address of the target bank node. The contract address is used for limiting the storage position of the liquidized data after initialization processing. For example, if the initialization common parameter is denoted pubData1, the parameter of the initialization common parameter takes the following form: pubData1= con1 (C1, B1). con1 represents a splice function and C1 represents a contract address.
The initialization score clearing parameter includes score clearing key information in a unified format, and the score clearing key information includes: payment source, payment destination, payment amount, and bank identification of the target bank node. For example, if the initialization score parameter is represented as preData1, the initialization score parameter containing the key information of the score may be represented in the form of: preData 1= con2(from, to, amplitude, code), con2 represents the concatenation function.
The signature parameter is generated by performing a second calculation according to the initialized common parameter and the initialized score parameter. The second calculation method is an agreed calculation method between the user node and the target bank node, and for example, the second calculation method is as follows: splicing the initialized public parameters and the initialized clearing parameters to obtain splicing parameters; performing Hash calculation on the splicing parameters; then the signature parameters sign1 satisfy the following expression: sign1= hash (pubData1+ preData 1).
In step S320, it is checked whether the contract general parameters are legal.
For example, the verification is performed based on the following function: checkIsNull (PreData1, pubData1, sign 1).
In the case where the above-described contract common argument check is legal, steps S330a and S340a are performed.
In step S330a, initial protocol data is generated according to the contract general parameters.
According to an embodiment of the present disclosure, in the step S330a, generating initial protocol data according to the contract general parameters includes: generating contract header data according to the contract address and the contract state; generating contract body data according to the initialized public parameters, the initialized liquidity parameters and the signature parameters; and splicing the contract header data and the contract body data to obtain initial protocol data.
For example, the process of generating the contract header data may be represented in the form of: conthead = con3(C1, status1), the process of generating contractual volume data may be represented in the form: privacyData 1= con4(preData1, pubData1, sign 1).
In step S340a, the initial protocol data is converted to obtain the target liquidation protocol data.
Based on the steps S310-S340 a, the clearing data is initialized based on the intelligent contract data conversion protocol to obtain a uniform entry form, so that contract general parameters related to the clearing data are obtained, the contract general parameters are further converted to obtain encrypted target clearing protocol data which is suitable for the entry form of the bank clearing data, and the clearing data in various forms and data structures of various banks to be docked need to be automatically converted and loaded, so that the application range is wide.
According to an embodiment of the present disclosure, as shown with reference to another branch indicated by a dotted line in fig. 3, the step S220 further includes the following step S330 b.
In the case where the contract general parameter check described above is not legal, step S330b is executed.
In step S330b, the execution of the intelligent contract data conversion protocol is terminated, and the contract status corresponding to the intelligent contract data conversion protocol is updated to the end status.
Fig. 4 schematically shows a detailed implementation flowchart of step S310 of the embodiment of the present disclosure.
According to an embodiment of the present disclosure, as shown in fig. 4, in the step S310, loading an intelligent contract data conversion protocol, taking the liquidation data as an input parameter of the intelligent contract data conversion protocol, and performing initialization processing to obtain a contract general parameter related to the liquidation data, includes the following steps: s410, S420, S430 and S440.
In step S410, the score data general template in the intelligent contract data conversion protocol is loaded, and a unique contract address is synchronously generated for the score data.
The general template for the score clearing data is used for limiting a uniform format of the entry parameter of the score clearing data protocol, the specific form of the specific uniform format is agreed by the protocol, and the score clearing data in any form can be converted into the format required by the template in the initialization step.
In step S420, the score data is initialized based on the score data general template to obtain the score key information in a unified format.
For example, the unified parameter is from, to, amount, code >. The sorting key information includes: payment source, payment destination, payment amount, and bank identification of the target bank node.
In step S430, a bank node address corresponding to the bank identifier in the key information for clearing is determined based on the built-in parameters of the blockchain system.
The built-in parameters include node information of each node in the blockchain system, including but not limited to: node identification information (for example, a node identification of a user node and a node identification of a bank node) of each node in the same blockchain system (or referred to as a blockchain network) and node address information corresponding to each node.
In step S440, a contract general parameter is generated according to the liquidation key information, the contract address and the bank node address.
For example, the contract general parameters generated are:
public parameter key factor: pri 1= hash (B1);
contract state: status1= init;
initializing common parameters: pubData1= con1 (C1, B1);
initializing a score clearing parameter: preData 1= con2(from, to, amount, code);
signature parameters: sign1= hash (pubData1+ preData 1).
The public parameter key factor is held between the user node and the corresponding bank node and is kept secret from outside, and is used for decrypting the encrypted parameter. The signature parameter is used for proving the uniqueness of the to-be-processed liquidation data corresponding to a group of contract general parameters in the transmission and processing processes, and if the liquidation data is illegally intercepted and tampered during transmission, the signature parameter cannot pass during verification, so that the correctness and the safety during the liquidation data processing can be ensured.

The bank clearing data template can be obtained through the node identification of the target bank node, for example, the node identification of the bank node is a bank code, such as boc (Chinese bank), icbc (industrial and commercial bank), and the like. The process of determining the bank liquidation data template can be represented by the following functions: conttctemplate = contcttemplate (bankcode).
The process of converting the initial protocol data to obtain the specific bank parameter data privcybankdata can be expressed as the following form:
privacybankData=contractConverts(contractTemplate)。
in step S520, the specific bank parameter data is encrypted to obtain encrypted target liquidation protocol data adapted to the entry form of the bank liquidation data.
For example, the target liquidation protocol data is represented as a contictbody, and the encryption process is represented as follows:
containtbody = sm4.encryption (privcybankdata). Encryption is an encryption algorithm.
