FIG. 1 is a schematic diagram of an application scenario of a blockchain-based transaction data processing system according to one or more embodiments of the present disclosure, as shown in FIG. 1, the system includes: the system comprises a first blockchain node, terminal equipment of a core enterprise user and terminal equipment of a provider user; the first blockchain node is a node in a blockchain, and the terminal equipment of the core enterprise user and the terminal equipment of the provider user can be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like, and the terminal equipment of the core enterprise user and the terminal equipment of the provider user are all in communication connection with the first blockchain node through a wireless network.

Specifically, a terminal device of a core enterprise user receives accounts payable data sent by the core enterprise user and sends the accounts payable data to a first blockchain node; the accounts payable data comprises account amount, user information (such as name, enterprise name of the enterprise, contact information and the like) of the provider user, account opening bank information (such as agricultural bank) of the provider user, account information (such as card number of a bank card) of the account opening bank of the provider user, payment mode and the like;

The first blockchain node is used for receiving accounts payable data sent by terminal equipment of a core enterprise user, and sending the accounts payable data to the terminal equipment of a provider user according to user information of the provider user included in the accounts payable data so as to enable the provider user to audit the accounts payable data; generating transaction credential data according to accounts payable data when receiving audit passing information sent by terminal equipment of a provider user; when a transaction request based on the transaction credential data sent by the terminal equipment of the provider user is received, corresponding transaction operation is executed according to the transaction request, transaction record information is generated, and the transaction record information is written into the blockchain;

the terminal equipment of the provider user receives the accounts payable data sent by the first blockchain node, displays the accounts payable data so that the provider user can conduct auditing, and sends the auditing passing information to the first blockchain node when the auditing passing information sent by the provider user is received, so that the first blockchain node generates transaction credential data according to the accounts payable data; and generating a transaction request according to the transaction data when the transaction data based on the transaction credential data sent by the provider user is received, and sending the transaction request to the first blockchain node. After receiving the account corresponding to the transaction credential data provided by the core enterprise user, the provider user can use the account to conduct transactions with other provider users, such as account transfer-out, transfer-in, financing and the like; correspondingly, the transaction data comprises the amount of the transaction account, the user information and the bank account information of the user of the transfer-out provider of the transaction account, the user information and the bank account information of the user of the transfer-in provider of the transaction account, and the like.

According to the transaction data processing system based on the blockchain, the transaction data is processed in the trusted environment of the blockchain, so that the transaction process is transparent and multiparty, and the authenticity and the effectiveness of the transaction are ensured; and by writing transaction record information into the blockchain, the non-tampering and public traceability of uplink data are ensured, the problems of data loss, data falsification and the like are effectively avoided, and an effective data basis is provided for transaction inquiry.

Fig. 2 is a flowchart of a blockchain-based transaction data processing method according to one or more embodiments of the present disclosure, where the method of fig. 2 can be performed by the first blockchain link point of fig. 1, and as shown in fig. 2, the method includes the following steps:

step S102, a first block link point receives accounts payable data sent by terminal equipment of a core enterprise user;

step S104, the first blockchain node generates transaction credential data according to the payable account data;

step S106, when the first block link point receives a transaction request based on transaction credential data sent by a terminal device of a provider user, corresponding transaction operation is executed according to the transaction request, and transaction record information is generated;

In step S108, the first blockchain link writes transaction record information into the blockchain.

In one or more embodiments of the present disclosure, by conducting transactions in a trusted environment of a blockchain, the transaction process is made public, transparent and multiparty, ensuring the authenticity and validity of the transaction; and by writing transaction record information into the blockchain, the non-tampering and public traceability of uplink data are ensured, the problems of data loss, data falsification and the like are effectively avoided, and an effective data basis is provided for transaction inquiry.

Since the accounts payable data includes the accounts amount and the related information of the suppliers, in order to ensure the accuracy of the transaction credential data generated based on the accounts payable data, in one or more embodiments of the present disclosure, as shown in fig. 3, step S102 includes:

step S102-2, the first block link point transmits the accounts payable data to the terminal equipment of the corresponding provider user according to the user information of the provider user included in the accounts payable data, so that the provider user can audit the accounts payable data;

step S102-4, if the first blockchain node receives the audit passing information sent by the terminal equipment of the provider user within the preset time period, transaction credential data is generated according to the accounts payable data.

Specifically, the first blockchain node sends the received accounts payable data to terminal equipment of the provider user according to the contact information included in the user information of the provider user, judges whether audit passing information sent by the terminal equipment of the provider user is received within a preset duration, and generates transaction credential data according to the accounts payable data when the judgment result is yes; if the judgment result is negative, sending transaction failure information to terminal equipment of a core enterprise user; the contact way is such as a mailbox, account information of a provider user on a financial platform of a supply chain and the like. Therefore, the accounts payable data is sent to the provider user for auditing, so that the risk of disputes caused by misoperation of generated transaction credential data due to misoperation of information included in the accounts payable data is reduced.

In one or more embodiments of the present disclosure, as shown in fig. 4, in step S106, a corresponding transaction operation is performed according to a transaction request, which includes:

Invoking an intelligent contract deployed in the blockchain, determining whether transaction data included in the transaction request meets a transaction rule of the transaction credential data based on the intelligent contract; and if the transaction data meets the transaction rule of the transaction credential data, executing corresponding transaction operation according to the transaction data.

The transaction data includes, but is not limited to, the amount of the transaction account, user information and bank account information of the transfer-out provider user of the transaction account, user information and bank account information of the transfer-in provider user of the transaction account. As an example, when the transaction request is used for requesting an account transfer (such as a transfer-out) operation, the account to be transferred is transferred out of the bank account corresponding to the bank account information of the transfer-out provider user and transferred into the bank account corresponding to the bank account information of the transfer-in provider user according to the amount of the account to be transferred included in the transaction data.

Further, if the transaction data does not meet the transaction rules of the transaction credential data, sending transaction failure information to the provider user.

Therefore, based on intelligent contracts in the blockchain, whether transaction data included in the transaction request meets the transaction rules of the transaction credential data is automatically determined, the phenomenon that a supplier user uses accounts provided by core enterprise users to conduct illegal transactions and the like is effectively avoided, and stable development of supply chain finance is promoted.

Further, in order to clarify transaction matters between the core enterprise and the provider, such as account amounts, transaction rules, etc., typically, the core enterprise and the provider will make a transaction contract; in order to ensure that the transaction rules satisfied by the transaction data determined based on the smart contract are consistent with the transaction rules agreed by the contract, in one or more embodiments of the present disclosure, as shown in fig. 4, before step S106, the method further includes:

step S105-2, the first block link point receives an electronic contract sent by terminal equipment of a core enterprise user;

specifically, the core enterprise user operates the terminal equipment thereof, and uploads an electronic contract signed by the core enterprise and the provider or an electronic scanning piece of the signed paper contract, which is collectively referred to as an electronic contract in the specification; the terminal equipment of the core enterprise user receives the electronic contract uploaded by the core enterprise user and sends the received electronic contract to the first block chain node, and the first block chain node receives the electronic contract sent by the terminal equipment of the core enterprise user. It should be noted that the electronic contract may be signed by the core enterprise user and the vendor, or by other users specified by the core enterprise and other users specified by the vendor; it should be further noted that the core enterprise user may upload the electronic contract before or after the accounts payable data is submitted, or may submit the accounts payable data and upload the electronic contract at the same time; that is, step S105-2 may be performed before step S102, after step S102, or simultaneously with step S102.

Step S105-4, the first blockchain node acquires transaction rules of transaction credential data in the electronic contract and deploys an intelligent contract in the blockchain according to the acquired transaction rules;

specifically, the first blockchain node searches a preset key field in the electronic contract, and takes the clauses comprising the key field as the transaction rules of the transaction credential data. The key field can be set according to the needs in practical application, for example, the key field comprises a financing ratio, and the term of the financing ratio field in the electronic contract, namely, the term that the financing ratio is not greater than 50% of the account amount, is used as a transaction rule of the transaction credential data.

The transaction rules are acquired in the electronic contracts sent by the terminal equipment of the core enterprise user, and the intelligent contracts are distributed in the blockchain according to the acquired transaction rules, so that the consistency of the intelligent contracts and the contract agreements is ensured, the user does not need to manually edit the transaction rules, the user operation is reduced, and the user experience is improved.

In practical application, because the accounts payable data sent by different core enterprise users are different, the transaction credential data generated by the first blockchain node according to the accounts payable data sent by different core enterprise users is different, so as to effectively distinguish the transaction credential data and enable the core enterprise users to conveniently query the circulation information of accounts provided by the core enterprise users, in one or more embodiments of the present disclosure, after step S102, the method further includes:

Step B1, a first block link point generates an identification of transaction credential data;

step B2, the first block link point sends the identification of the transaction credential data to the terminal equipment of the core enterprise user so that the core enterprise user inquires the circulation information of accounts corresponding to the transaction credential data according to the identification of the transaction credential data;

specifically, the first block link point sends the transaction credential data and the identification of the transaction credential data to the terminal equipment of the core enterprise user, so that the core enterprise user inquires the circulation information of accounts corresponding to the transaction credential data according to the identification of the transaction credential data; and sending the transaction credential data to a terminal device of the vendor user in correspondence with the identification of the transaction credential data to cause the vendor user to initiate a transaction request based on the transaction credential data.

Correspondingly, in step S106, transaction record information is generated, including:

and carrying out association record on the identification of the transaction credential data, the amount of the transaction account included in the transaction request, the user information of the user who withdraws the transaction account from the provider and the user information of the user who withdraws the transaction account from the provider, and taking the recorded information as transaction record information.

Further, in order to avoid that the accounts payable data is maliciously tampered and inconsistent with the transaction credential data, in one or more embodiments of the present disclosure, after step B1, the method further includes: the accounts payable data, the transaction credential data, and the identity of the transaction credential data are recorded in association and the recorded information is written into the blockchain.

Furthermore, since the transaction rules agreed between different core enterprises and different suppliers are different, the intelligent contracts deployed by the first blockchain node according to the different transaction rules are also different; in order to effectively differentiate the smart contracts and effectively identify the smart contracts corresponding to different transaction credential data, in one or more embodiments of the present disclosure, after step S105-4, the method further includes:

step C1, a first block chain link point generates a contract identification of an intelligent contract;

and C2, the first block link point carries out association record on the identification of the generated transaction certificate data and the contract identification to obtain association record information.

By associating and recording the generated identification of the transaction credential data with the contract identification, when a transaction request based on the transaction credential data is received, the intelligent contract to be invoked is determined according to the identification of the transaction credential data included in the transaction request and the obtained association record information. That is, in one or more embodiments of the present description, invoking the smart contract deployed in the blockchain in step A1 includes:

step D1, the first block link point acquires a corresponding contract identification from the associated record information according to the identification of the transaction credential data included in the transaction request;

And D2, the first blockchain node calls the intelligent contract corresponding to the acquired contract identification.

In a specific embodiment, taking the example that the first block link point receives accounts payable data and an electronic contract sent by a terminal device of a core enterprise user at the same time, as shown in fig. 5, the method includes:

step S202, a first block link point receives accounts payable data and an electronic contract sent by terminal equipment of a core enterprise user;

step S204, the first blockchain node sends the payable account data to the terminal equipment of the corresponding supplier user according to the user information of the supplier user included in the payable account data;

step S206, the first block chain node judges whether the audit passing information sent by the terminal equipment of the provider user is received within the preset time period, if yes, step S208 is executed, otherwise, transaction failure information is sent to the terminal equipment of the core enterprise user;

step S208, the first blockchain node generates transaction credential data according to the payable account data and generates an identifier of the transaction credential data;

step S210, the first block link correlates records of accounts payable data, transaction credential data and identifications of the transaction credential data, writes the recorded information into the block chain, and correspondingly sends the accounts payable data and the accounts payable data identifications to terminal equipment of a core enterprise user and terminal equipment of a provider user respectively;

Step S212, the first blockchain node searches a preset key field in the electronic contract, and takes the clauses comprising the key field as a transaction rule of transaction credential data;

step S214, the first block chain link point deploys the intelligent contract in the block chain according to the transaction rule, and generates a contract identification of the intelligent contract;

step S216, the first block link point carries out association record on the identification of the generated transaction voucher data and the contract identification to obtain association record information;

step S218, when the first block link point receives a transaction request based on transaction credential data sent by a terminal device of a provider user, acquiring a corresponding contract identification from the associated record information according to an identification of the transaction credential data included in the transaction request;

step S220, the first blockchain node calls a corresponding intelligent contract according to the acquired contract identification, determines whether transaction data included in the transaction request meets the transaction rule of the transaction credential data based on the intelligent contract, if yes, step S222 is executed, and otherwise, transaction failure information is sent to terminal equipment of a provider user;

step S222, the first block link point executes corresponding transaction operation according to the transaction data, and carries out association record on the identification of the transaction data and the transaction voucher data, and the recorded information is used as transaction record information;

In step S224, the first block link writes the transaction record information into the block chain, and sends the transaction success information to the terminal device of the provider user.

step S306, the second blockchain node generates a circulation path diagram of accounts corresponding to the transaction credential data to be queried according to the acquired transaction record information;

in step S308, the second block link point sends the generated circulation path diagram to the terminal device of the core enterprise user, so that the terminal device of the core enterprise user displays the circulation path diagram.

In one or more embodiments of the present disclosure, based on transaction record information stored in a blockchain, effective query of transactions is achieved, and meanwhile, by generating a circulation path diagram of accounts corresponding to transaction credential data to be queried and sending the generated circulation path diagram to terminal equipment of a core enterprise user, the core enterprise user can clearly and clearly view all circulation information of accounts corresponding to the transaction credential data to be queried, without manually carding the circulation information of accounts according to each transaction record information by the core enterprise user, so that query efficiency and user experience are improved.

In one or more embodiments of the present disclosure, as shown in fig. 8, step S304 includes:

step S304-2, the second block link point matches the identification of the transaction credential data to be queried with the identification of the transaction credential data contained in the transaction record information stored in the block chain;

step S304-4, if the matching is successful, the second block link points the corresponding transaction record information as the transaction record information corresponding to the identification of the transaction credential data to be queried.

Therefore, the core enterprise user can realize the inquiry of the corresponding transaction only by providing the identification of the transaction credential data to be inquired, and the core enterprise user does not need to provide excessive inquiry information, so that the convenience of transaction inquiry is improved.

Generally, the core enterprise user performs transaction inquiry mainly to inquire the transfer information of the transfer provided by the core enterprise user, such as the amount of the transaction account corresponding to each transfer node, the user information of the transfer provider user of the transaction account, and the user information of the transfer provider user in the transfer process, and based on this, in one or more embodiments of the present disclosure, as shown in fig. 9, step S306 includes:

step S306-2, the second blockchain node acquires the amount of the transaction account, the user information of the transfer-out provider user of the transaction account and the user information of the transfer-in provider user in the acquired transaction record information;

In step S306-4, the second blockchain node generates a circulation path diagram of the accounts corresponding to the transaction credential data to be queried according to the acquired amount of the transaction accounts, the user information of the transfer-out provider user of the transaction accounts and the user information of the transfer-in provider user.

The partial structure of the circulation path diagram can be seen in fig. 10, where the nodes where the core enterprise user and each supplier user are located are circulation nodes, that is, the circulation path diagram includes at least one circulation node, and the connected circulation nodes form an account circulation path, for example, the circulation nodes where the core enterprise user, the supplier user 1, the supplier user 3, and the supplier user 8 are located are one account circulation path, and in this embodiment, the account circulation path is denoted as "core enterprise user-supplier user 1-supplier user 3-supplier user 8".

Considering that most users have a habit when using a mouse, that is, the position of the cursor of the mouse is the current focused position of the user, in order to enable the core enterprise user to have better query experience, in one or more embodiments of the present disclosure, the method further includes:

If the second block chain link point detects that the cursor is positioned at the circulation node or detects the triggering operation of the core enterprise user on the circulation node;

and acquiring a corresponding account transfer path in the transfer path diagram by taking the transfer node where the cursor is positioned as an end point or taking the transfer node where the operation is triggered as an end point and taking the transfer node where the core enterprise user is positioned as a starting point, and distinguishing and displaying the acquired account transfer path.

The mode of distinguishing display, such as highlighting display, color change display, thickening display and the like, can be set according to the needs in practical application. As an example, as shown in fig. 11, when the second blockchain node detects that the cursor is located at the circulation node where the provider user 2 is located, the circulation node where the provider user 2 is located is taken as an end point, the node where the core enterprise user is located is taken as a start point, the corresponding account circulation path is obtained in the circulation path diagram as "core enterprise user-provider user 1-provider user 2", and the transfer circulation path is bolded and displayed. Therefore, the position of the cursor is detected, or the triggering operation of the core enterprise user on the circulation node is detected, and the corresponding account circulation paths are displayed in a distinguishing mode, so that the account circulation paths can be displayed to the core enterprise user more intuitively, and human-computer interaction experience is improved for the core enterprise user.

Further, since the core enterprise user generally performs a transfer-out operation on accounts corresponding to the transaction credential data to be queried, so as to provide accounts to the provider user, the provider user can use the accounts to perform a plurality of transaction operations such as transfer-out, transfer-in, financing and the like with other providers; in order to enable the core enterprise user to query the core enterprise user and the transaction information of each transaction operation performed by each provider user for accounts, in one or more embodiments of the present disclosure, each circulation node includes a transfer-out query control, and/or a transfer-in query control, and/or a financing query control, and the corresponding method further includes:

if the second block chain link point detects that the cursor is positioned in the out-of query control or detects the triggering operation of the out-of query control by the core enterprise user, taking the circulation node in which the cursor is positioned as an out-of node or taking the circulation node triggered to operate as an out-of node; determining a first-level receiving node for receiving the accounts transferred by the transfer-out node; displaying account transfer-out information of a transfer-out node, and distinguishing and displaying the transfer-out node and a primary receiving node;

if the second blockchain node detects that the cursor is positioned in the transfer-in query control or detects the triggering operation of the core enterprise user on the transfer-in query control, the transfer node in which the cursor is positioned is used as a transfer-in node or the transfer node subjected to the triggering operation is used as a transfer-in node; determining a first-stage transfer-out node of the account received by the transfer-in node; displaying account transfer information of the transfer node, and distinguishing and displaying the transfer node and the first-stage transfer node;

And if the second block link point detects that the cursor is positioned in the financing inquiry control or detects the triggering operation of the core enterprise on the financing inquiry control, displaying corresponding financing information.

The first-level receiving node is a node for directly receiving accounts transferred by a transferring node for the transferring node; the first-stage transfer-out node is a node for directly transferring accounts to a transfer-in node; the specific contents of the account transfer information, the account transfer information and the financing information can be set automatically according to the needs in practical application, for example, the account transfer information comprises transfer amount and the like, the account transfer information comprises transfer amount, transfer time and the like, and the financing information comprises financing amount, financing time and the like. As an example, referring to fig. 12, if the second block link point detects that the cursor is located on the forwarding query control of the forwarding node where the provider user 1 is located, the forwarding node where the provider user 1 is located is taken as the forwarding node, the forwarding nodes where the provider user 2 and the provider user 3 are located are taken as the primary receiving nodes, account forwarding information of the forwarding node where the provider user 1 is located is displayed, and the forwarding nodes where the provider user 1, the provider user 2 and the provider user 3 are located are bolded; referring to fig. 13, if the second block link point detects a trigger operation of the core enterprise user on the transfer inquiry control of the transfer node where the provider user 5 is located, the transfer node where the provider user 5 is located is taken as a transfer node, the transfer node where the provider 2 is located is taken as a first-level transfer node, account transfer information of the transfer node where the provider user 5 is located is displayed, and the transfer nodes where the provider 2 and the provider 5 are located are bolded; referring to fig. 14, if the second block link point detects that the cursor is located on the financing query control of the circulation node where the provider user 3 is located, financing information of the circulation node where the provider user 3 is located is displayed.

Therefore, the inquiry of transaction information of different transaction operations is realized, and the user information of two or more provider users directly carrying out transactions can be more intuitively seen by the core enterprise users through distinguishing and displaying the transfer-out node and the first-level receiving node and distinguishing and displaying the transfer-in node and the first-level transfer-out node; therefore, various transaction information is integrated through one graph, a circulation path graph of a plurality of accounts is not required to be generated according to transaction types or transaction amounts, or circulation information tables of the accounts are not required to be generated, so that the response rate of transaction inquiry requests is improved, core enterprise users do not need to switch among the circulation path graphs of the accounts or circulation information tables of the accounts, and the inquiry experience of the core enterprise users is greatly improved.

It should be noted that the flow path diagrams shown in fig. 10 to 14 are only for illustration and not for limitation, and the patterns of the flow path diagrams can be designed according to the needs in practical application.

In one or more embodiments of the present disclosure, when receiving a transaction inquiry request sent by a terminal device of a core enterprise user at a second block link point, where the transaction inquiry request includes an identifier of transaction credential data to be inquired; the second blockchain node obtains corresponding transaction record information in the blockchain according to the identification of the transaction credential data to be queried, generates a circulation path diagram of accounts corresponding to the transaction credential data to be queried according to the obtained transaction record information, and sends the circulation path diagram to the terminal equipment of the core enterprise user so that the terminal equipment of the core enterprise user can display the circulation path diagram.

In the 70 s of the 30 th century, improvements to one technology could clearly be distinguished as hardware improvements (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software improvements (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K30, and Silicone Labs C8051F330, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
