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 early warning system based on the blockchain, the intelligent contract is distributed in the blockchain according to the transaction rule by acquiring the transaction rule of the transaction credential data, so that the transaction request sent by the terminal equipment of the supplier user is automatically subjected to early warning analysis based on the intelligent contract, the account provided by the core enterprise is effectively monitored, the phenomenon that the supplier user utilizes the account provided by the core enterprise to conduct illegal transaction and the like is avoided, and the stable and orderly development of supply chain finance is promoted.

FIG. 2 is a flow diagram of a blockchain-based transaction pre-warning method provided by one or more embodiments of the present disclosure, where the method of FIG. 2 can be performed by the blockchain node of FIG. 1, as shown in FIG. 2, and the method includes the steps of:

step S102, block chain link points receive accounts payable data sent by terminal equipment of a core enterprise user;

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

step S106, the block chain link points acquire transaction rules of the transaction voucher data, and intelligent contracts are deployed in the block chain according to the acquired transaction rules;

step S108, when the blockchain node receives a transaction request based on transaction credential data sent by terminal equipment of a provider user, early warning analysis is carried out on the transaction request based on the deployed intelligent contract.

In one or more embodiments of the present disclosure, early warning analysis is automatically performed on a transaction request sent by a terminal device of a supplier user based on an intelligent contract deployed in a blockchain, so that effective supervision of accounts provided by a core enterprise is achieved, illegal transactions and other phenomena performed by the supplier user using accounts provided by the core enterprise are avoided, and stable and orderly development of supply chain finance is promoted.

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 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 blockchain node receives the audit passing information sent by the terminal equipment of the provider user within the preset time, generating transaction credential data according to the accounts payable data.

Specifically, the block chain link point 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 time length, and generates transaction credential data according to the accounts payable data when the judgment result is yes; if the judgment result is negative, the blockchain node sends transaction failure information to the terminal equipment of the 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.

Typically, in order to clarify transaction matters between the core enterprise and the provider, such as account amounts, transaction rules, etc., the core enterprise and the provider will sign a transaction contract; further, in order to minimize the user operation and avoid unnecessary trouble caused by input errors when the user manually inputs information, in one or more embodiments of the present disclosure, step S104 further includes:

step A, a block chain 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; and 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 blockchain node, and the blockchain 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, the step a may be performed before the step S102, may be performed after the step S102, or may be performed simultaneously with the step S102.

Correspondingly, step S104 includes:

the blockchain node searches a preset key field in the received 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 method comprises the steps that the clauses comprising preset key fields are obtained from the electronic contract sent by the terminal equipment of a core enterprise user, the obtained clauses are used as the transaction rules of transaction evidence data, and user operation is reduced on the basis of ensuring consistency of the transaction rules and contract agreements; and the validity of the intelligent contract deployed based on the transaction rule is ensured, and the accuracy and the validity of the early warning analysis result are further ensured.

Because accounts payable data sent by different core enterprise users are different, transaction rules agreed between different core enterprises and different suppliers are different, so that transaction credential data generated by blockchain nodes according to accounts payable data sent by terminal equipment of different core enterprise users are different, and intelligent contracts deployed according to the transaction rules of the transaction credential data are also different; in order to effectively differentiate the transaction credential data, effectively differentiate the smart contracts, and accurately identify the smart contracts corresponding to different transaction credential data, in one or more embodiments of the present disclosure, after step S104, the method further includes:

Step B, the block chain link point generates an identification of transaction credential data;

after step S106, the method further includes:

step C1, generating contract identification of an intelligent contract by block chain link points;

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

Further, considering that the core enterprise user and the provider user may have a plurality of transaction credential data, in order for the core enterprise user and the provider user to distinguish and manage their respective transaction credential data, and query the transaction records of the transaction credential data, step B further includes: the block link point sends the generated transaction credential data to the terminal equipment of the core enterprise user and the terminal equipment of the provider user in correspondence with the identification of the transaction credential data.

The intelligent contract for early warning analysis is determined according to the identification of the transaction credential data and the associated record information when the transaction request based on the transaction credential data is received. Specifically, as shown in fig. 4, in step S108, early warning analysis is performed on the transaction request based on the smart contract, including:

Step S108-2, the block link point obtains an associated contract identification from the associated record information according to the identification of the transaction credential data included in the transaction request;

step S108-4, the blockchain node calls a corresponding intelligent contract according to the acquired contract identification, determines whether transaction data meets the transaction rule of the transaction credential data based on the called intelligent contract, if so, executes step S108-6, and if not, executes step S108-8;

step S108-6, the block link point executes corresponding transaction operation according to the transaction data included in the transaction request, generates transaction record information, writes the transaction record information into the block chain, and sends transaction success information to terminal equipment of a provider user;

specifically, the block link point executes corresponding transaction operation according to the transaction data included in the transaction request, records the transaction data in association with the identification of the transaction voucher data, takes the recorded information as transaction record information, writes the transaction record information into the block chain, and sends transaction success information to the terminal equipment of the provider user.

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 a bank account corresponding to the bank account information of the transfer-out supplier user with an amount of the account to be transferred included in the transaction data, and transferred into the bank account corresponding to the bank account information of the transfer-in supplier user, and the identification of the transaction credential data, the amount of the account to be transferred, the transfer time of the account to be transferred, the identity information of the transfer-out supplier user, the bank account information, the identity information of the transfer-in supplier user, and the bank account information are associated and recorded, and the recorded information is used as transaction record information, the transaction record information is written into the blockchain, and the transaction success information is transmitted to the terminal device of the supplier user.

In step S108-8, the blockchain node sends transaction failure information to the terminal device of the provider user.

Therefore, the intelligent contract automatically performs early warning analysis on the transaction request sent by the terminal equipment of the provider user to determine whether the transaction data meets the transaction rule of the transaction credential data, so that the phenomena that the provider user performs illegal transaction by using account provided by a core enterprise are avoided, the effective supervision of the account provided by the core enterprise is realized, and the sustainable development of supply chain finance is promoted. Meanwhile, by writing transaction record information into the blockchain, the non-tamper property and the disclosure and the investigation property of transaction data are ensured, and a data basis is provided for inquiring the transaction of the accounts provided by the core enterprise user. Based on this, in one or more embodiments of the present description, the method further comprises:

step D1, a block link point receives a transaction inquiry request sent by terminal equipment of a core enterprise user, wherein the transaction inquiry request comprises identification of transaction credential data to be inquired;

step D2, the blockchain node acquires corresponding transaction record information from the blockchain according to the identification of the transaction credential data to be queried;

Specifically, the block link point matches the identification of the transaction credential data to be queried with the identification of the transaction credential data in the transaction record information stored in the block chain; if the matching is successful, the corresponding transaction record information is used as the transaction record information corresponding to the identification of the transaction credential data to be queried.

Step D3, the blockchain node generates a circulation path diagram of accounts corresponding to the identification of the transaction credential data to be queried according to the acquired transaction record information;

specifically, the blockchain node acquires the amount of the transaction account, the user information of the user of the provider from which the transaction account is transferred and the user information of the user of the provider from which the transaction account is transferred in the transaction record information; and generating a circulation path diagram of the accounts corresponding to the identification of the transaction credential data to be queried according to the 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.

And D4, the block chain link point sends the circulation path diagram to the terminal equipment of the core enterprise user so as to display the circulation path diagram on the terminal equipment of the core enterprise user.

The circulation path diagram of the accounts corresponding to the identification of the transaction credential data to be inquired is generated, and the circulation path diagram is sent to the terminal equipment of the core enterprise user, so that all circulation nodes of the corresponding accounts are clearly and clearly displayed to the core enterprise user, the core enterprise user does not need to manually comb the circulation process of the accounts, and the inquiring experience of the core enterprise user is improved.

In one or more embodiments of the present disclosure, in order to avoid that the accounts payable data is maliciously tampered with and inconsistent with the transaction credential data, after the step B, 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.

In practical application, some provider users exist, after accounts provided by core enterprise users are received, no transaction operation is performed on the accounts, so that the accounts cannot be played, and risks such as illegal fund collection exist; in one or more embodiments of the present disclosure, a core enterprise user may set an operation period for performing a transaction operation on all accounts or a part of accounts corresponding to an account amount provided by the core enterprise user by a provider user, and when the operation period is reached, remind the provider user if it is determined that the provider user does not perform the transaction operation on all or a part of accounts provided by the core enterprise user; specifically, the method further comprises the steps of:

step E1, receiving an operation period of transaction operation of all accounts or part of accounts corresponding to the accounts by a provider from terminal equipment of a core enterprise user by a block link point;

Step E2, when the core enterprise user pays all accounts or part of accounts corresponding to the account amount to the provider user, the blockchain node records the payment time;

and E3, the blockchain node counts the time by taking the payment time as the starting time, and if the operation period is reached, the blockchain node determines that the supplier user does not conduct transaction operation on all accounts or part of accounts corresponding to the account amount, and then sends prompt information to the terminal equipment of the supplier user.

Specifically, the blockchain node counts the time by taking the payment time as the starting time, when the operation period is reached, corresponding transaction record information is searched in the blockchain according to the identification of the transaction certificate data, if the corresponding transaction record information is searched, the fact that the provider user performs transaction operation on all accounts or part of accounts corresponding to the account amount in the operation period is determined, if the corresponding transaction record information is not searched, the fact that the provider user does not perform transaction operation on all accounts or part of accounts corresponding to the account amount in the operation period is determined, and prompt information is sent to terminal equipment of the corresponding provider user.

In a specific embodiment, taking the example that the 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 S208, the blockchain node generates transaction credential data according to the payable account data and generates an identifier of the transaction credential data;

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

step S212, the 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 block chain link points distribute intelligent contracts in the block chain according to transaction rules and generate contract identifications of the intelligent contracts;

step S216, the 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;

In the 40 s of the 20 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 PIC18F26K20, and Silicone Labs C8051F320, 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.
