Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the following will be combined with the drawings in one or more embodiments of this specification to compare the technical solutions in one or more embodiments of this specification. The technical solution is described clearly and completely. Obviously, the described embodiments are only a part of the embodiments in this specification, rather than all the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this document.

Figure 1 is a schematic diagram of an application scenario of a blockchain-based transaction query method provided by one or more embodiments of this specification. As shown in Figure 1, the application scenario includes: the first blockchain node and core enterprise users Terminal equipment; among them, the first blockchain node is a node in the blockchain, and the terminal equipment of core enterprise users can be mobile phones, tablets, desktop computers, portable notebook computers, etc., and the terminal equipment of core enterprise users passes through the wireless network Communicate with the first blockchain node;

Specifically, the terminal device of the core enterprise user receives the time to be queried and the identification of the transaction voucher data to be queried sent by the core enterprise user, generates a transaction query request according to the time to be queried and the identification of the transaction voucher data to be queried, and Send a transaction query request to the first blockchain node; the first blockchain node receives the transaction query request sent by the terminal device of the core enterprise user, and obtains the corresponding data from the blockchain according to the identification of the transaction voucher data to be queried The target transaction record information when the transaction time is within the time to be queried; the first blockchain node calls the first smart contract, and generates the account corresponding to the transaction voucher data to be queried according to the acquired target transaction record information. Within the time to be queried The distribution map represents the distribution of accounts among account holders within the time to be queried; the first blockchain node sends the generated distribution diagram to the terminal devices of core enterprise users; the core The terminal device of the enterprise user receives the distribution map sent by the first blockchain node, and displays the received distribution map, so that the core enterprise user can view the distribution status of the accounts provided by it. As a result, based on the transaction record information stored in the blockchain, the core enterprise can effectively query the distribution status of the accounts it provides among the account holders.

Based on the above application scenario architecture, one or more embodiments of this specification provide a blockchain-based transaction query method. Figure 2 is a blockchain-based transaction query method provided by one or more embodiments of this specification Schematic diagram of the process, the method in Fig. 2 can be executed by the first blockchain node in Fig. 1, as shown in Fig. 2, the method includes the following steps:

Step S102, receiving a transaction query request sent by a terminal device of a core enterprise user, where the transaction query request includes the time to be queried and the identification of the transaction voucher data to be queried;

Step S104, according to the identification of the transaction voucher data, obtain corresponding target transaction record information from the blockchain and the transaction time is within the time to be queried;

Step S106: Invoke the first smart contract to generate a distribution map of the accounts corresponding to the transaction voucher data to be queried during the time to be queried according to the target transaction record information, where the distribution map represents the distribution of the accounts during the time to be queried The distribution of account holders among users;

In step S108, the distribution map is sent to the terminal device of the core enterprise user, so that the terminal device of the core enterprise user displays the distribution map.

In one or more embodiments of this specification, based on the transaction record information stored in the blockchain, the core enterprise can effectively query the distribution status of the accounts it provides among the account holders; and, By generating the distribution map of the accounts corresponding to the transaction voucher data to be queried, core enterprise users can clearly and at a glance view the distribution of the accounts they provide during the time to be queried, without the need for core enterprise users to follow Transaction record information manually sorts out the distribution of accounts, which improves query efficiency and user experience.

In order to avoid the loss or tampering of transaction data of transactions based on accounts provided by core enterprises between supplier users, and between supplier users and other institutions (such as banks), one or more embodiments of this specification When the second blockchain node receives the transaction request sent by the terminal device of the supplier user, it executes the corresponding transaction operation according to the transaction request, and generates the transaction record according to the transaction time, the identification of the transaction voucher data included in the transaction request, etc. Information, and write transaction record information into the blockchain to provide an effective data basis for transaction query; among them, the specific generation process of transaction record information will be described in detail later, the second blockchain node and the first area The blockchain nodes can be the same blockchain node or different blockchain nodes. Based on this, as shown in FIG. 3, step S104 includes:

Step S104-2: Match the identification of the transaction voucher data to be queried with the identification of the transaction voucher data contained in the transaction record information stored in the blockchain, and match the time to be queried with the transaction record information stored in the blockchain To match the transaction time;

In step S104-4, if the matching is successful, the corresponding transaction record information is used as the target transaction record information.

Specifically, the identification of the transaction voucher data to be queried is matched with the identification of the transaction voucher data contained in the transaction record information stored in the blockchain, and if the matching fails, the transaction record where the identification of the failed transaction voucher data is located is determined The information is not the transaction record information of the account corresponding to the transaction voucher data to be queried; if the matching is successful, it is determined that the transaction record information where the identifier of the successfully matched transaction voucher data is located is the transaction record of the account corresponding to the transaction voucher data to be queried Information, the transaction time is read from the transaction record information where the identifier of the successfully matched transaction voucher data is located, and the read transaction time is matched with the time to be queried. If the match is successful, the transaction record where the successful transaction time is located will be matched The information serves as the target transaction record information. It should be pointed out that if the target transaction record information is not obtained, the prompt information is sent to the terminal device of the core enterprise user.

Further, in the embodiment of this specification, the time to be queried can be a certain moment (such as 12: 0: 0 on August 15, 2019), or a certain period of time (such as August 1, 2019 to 2019). August 15), core enterprise users can operate their terminal devices to make settings. When the time to be queried is a certain moment, correspondingly, matching the read transaction time with the time to be queried includes: determining whether the read transaction time is before the time to be queried, if yes, the matching is successful, otherwise the matching fails; for example, , The read transaction time is 3:2:15 on August 3, 2019. Before 12:0:0 on August 15, 2019, the match is determined to be successful. When the time to be queried is a certain period of time, correspondingly, matching the read transaction time with the time to be queried includes: determining whether the read transaction time is within the time to be queried, if yes, the matching is successful, otherwise the matching fails; For example, if the transaction time read is August 10, 2019, it is determined that the matching is successful within August 1, 2019 to August 15, 2019.

Considering that the query time set by the core enterprise users may be a small span of time, or just a certain moment, it may also be a large span of time, in order to improve the readability and aesthetics of the distribution graph to be generated In one or more embodiments of this specification, the time division rule is preset to divide the time to be queried into at least one time period, so as to count the accounts held by each account holder user in each time period. Status information, and generate a distribution map to avoid the problem that the span of the time period is too large to be displayed in a distribution diagram; it should be pointed out that when the time to be queried is a certain moment, the divided time period is that moment . Specifically, as shown in FIG. 4, step S106 includes step S106-2 to step S106-10.

Step S106-2: Invoke the first smart contract, and divide the time to be queried into at least one time period according to a preset time division rule.

Among them, the time division rule can be set according to the needs in actual applications. For example, when the waiting time is less than 5 days, the time can be divided by 12 hours as the division unit, that is, every 12 hours is a time period for time division; When the query time is between 5 and 30 days, it can be divided by 24 hours, that is, each time period is 1 day; when the query time is between 30 days and 50 days, it can be divided by 48 hours Time division, that is, each time period is 2 days.

Step S106-4: Obtain the transaction time, the amount of the transaction account, the user information of the outgoing user and the user information of the incoming user from the target transaction record information.

Step S106-6: Regard the transfer-out user and transfer-in user as account holder users, according to the acquired transaction time, the amount of the transaction account, the user information of the transfer-out user and the transfer-in user's user information of the transaction account, Determine the status information of the accounts held by each account holder user in each time period.

Specifically, the transfer-out user and transfer-in user of the transaction account are regarded as account holder users, and the user information of the transfer-out user and the user information of the transfer-in user of the transaction account are regarded as the users of each account holder. Information, which distinguishes users who hold accounts, where user information includes user name, user contact information, etc.; according to the transaction time in the target transaction record information, determine the target transaction record information corresponding to each time period; according to The target transaction record information corresponding to each time period, statistics of the amount of accounts held by each account holder user in each time period, and the accounts held by each account holder user in each time period The proportion of the total amount of accounts provided by the core company and other information.

For example, using 24 hours as the division unit for time division, that is, each time period is 1 day, and the target transaction record information includes:

Transaction time: at 6 o'clock on August 1, 2019, the user information of the account transfer user: core companies, etc., the user information of the account transfer user: supplier A, the transaction account amount: 1 million yuan;

Transaction time: at 15:00 on August 4, 2019, the user information of the user who transfers the account: supplier A; the user information of the user who transfers the account: supplier B, the transaction account amount: 1 million;

Transaction time: at 9 o'clock on August 6, 2019, the user information of the account transfer-out user: supplier B, the user information of the account transfer user: supplier C; transaction account amount: 600,000;

Transaction time: At 15:00 on August 6, 2019, the user information of the account transfer-out user: supplier B, etc., the account transfer user's user information: to the supplier D, etc., transaction account amount: 200,000;

Transaction time: at 12 o'clock on August 11, 2019, the user information of the account transfer user: supplier D, etc., the account transfer user user information: Bank 1, etc., transaction account amount: 50,000;

Transaction time: at 9 o'clock on August 14, 2019, the user information of the account transfer user: supplier C, etc., the user information of the account transfer user: supplier E, the transaction account amount: 450,000;

Transaction time: at 10 o'clock on August 14, 2019, the user information of the account transfer user: supplier C, etc., the account transfer user user information: Bank 1, the transaction account amount: 150,000;

Transaction time: at 13:00 on August 14, 2019, the user information of the account transfer user: supplier D, etc., the account transfer user user information: Bank 1, etc., transaction account amount: 50,000;

From the above transaction record information statistics, the status information of the accounts held by each account holder user in each time period (taking the holding amount as an example) is as follows:

It should be pointed out that the form of the status information of the accounts held by each account holder user at each time period based on the target transaction record information is not limited to the above forms, and it can be used according to needs in actual applications. Settings, such as creating a separate form for each account holder user.

In step S106-8, among the preset filling patterns, different filling patterns used to characterize each account holder user are selected;

Among them, the filling style can be set according to actual needs, such as color filling, pattern filling, etc.

Step S106-10, according to the time sequence, according to the selected filling pattern and the determined status information, generate a distribution map of the accounts corresponding to the transaction voucher data among the account holders within the time to be queried.

Among them, the distribution diagram generated according to the selected filling style and the aforementioned determined status information is shown in Figure 5. The distribution diagram includes a main body part and an annotation part. The main body part shows the distribution of accounts among users. The comment part includes the user information (such as user name) of each account holder and the associated information of the filling style; further, it can be seen from the distribution diagram shown in Figure 5: the time period is August 1, 2019 to the time period On August 3, 2019, the accounts of 1 million were distributed to the account holder user supplier A; during the time period of August 4, 2019 and August 5, 2019, the accounts of 1 million were distributed to the account holders. There is user supplier B; from August 6 to August 10, 200,000 accounts are distributed to the account holder user provider B, and 600,000 accounts are distributed to the account holder user supplier Department C, 200,000 accounts are distributed to account holder user supplier D; from August 11, 2019 to time period August 13, 2019, 200,000 accounts are distributed to account holder user provider D Office B and 600,000 accounts are distributed at the account holding user supplier C, 150,000 accounts are distributed at the account holding user provider D, and 50,000 accounts are distributed at the account holding user’s bank 1. During the time period August 14, 2019 and time period August 15, 2019, 200,000 accounts were distributed to the account holder user supplier B, and 450,000 accounts were distributed to the account holder user supplier E. 100,000 accounts are distributed at the account holder user provider D, and 250,000 accounts are distributed at the account holder 1 bank.

It can be seen that the core enterprise users only need to provide the identification of the time to be queried and the transaction voucher data to be queried, and the corresponding accounts can be effectively inquired about the distribution status of the account holders, and there is no need for the core enterprise users to trade Record the information and perform operations such as integration, and you can see the distribution of the accounts it provides in each time period at a glance from the distribution diagram.

Considering that most users have a habit of using the mouse, that is, the position of the mouse cursor is the position that the user is currently paying attention to. Based on this, in order to allow core enterprise users to have a better query experience, this manual has multiple implementations. In the example, the method also includes:

Step A2, if it is detected that the cursor is located in the main part of the distribution map, then obtain the position information where the cursor is located; or if the core enterprise user's trigger operation on the main part of the distribution map is detected, obtain the position information of the operated position;

Step A4: Determine the target time period closest to the acquired location information;

Specifically, the first distance between the position information obtained by measurement and its adjacent time period, and the second distance between the position information obtained by measurement and its adjacent time period, compare the first distance with the first distance Second, the size of the distance, and the time period corresponding to the small distance is regarded as the target time period.

Step A6: Determine the distribution information of the account among the account holders within the target time period;

Specifically, from the aforementioned statistics of the status information of the accounts held by the account holders in each time period, the status information of the accounts held by the account holders in the target time period is obtained, and according to the obtained The status information of the account is generated during the target time period among the account holders. Among them, the specific content of the distribution information can be set according to the needs in actual applications. For example, the distribution information includes time information, holdings Each account of the account holds the user name of the user, and each account of the account holds information such as the amount of the account held by the user.

Step A8, display the determined distribution information.

Among them, a schematic diagram showing distribution information can be seen in Figure 6.

By detecting the position of the mouse cursor, or detecting the triggering operation of the core enterprise user on the main part of the distribution map, and displaying the corresponding account distribution information, the core enterprise user can more clearly understand the account payment in a certain period of time. The distribution of account holders among users is conducive to improving the human-computer interaction experience and query experience of core enterprise users.

Further, the distribution map can not only reflect the distribution of accounts among the account holders, but also reflect the change status of accounts at a certain account holder, that is, each filling method corresponds to The change of the area over time reflects the change over time of the account at a certain account holder user. However, when there are many account holders, especially when different colors are used to represent different account holders, the borders of different filling patterns in the distribution map may be indistinguishable by the naked eye, making core enterprise users It becomes difficult to check the account changes in a certain account holder user. Based on this, one or more embodiments of this specification further include:

Since the accounts payable data includes the amount of the accounts and the supplier’s related information, in order to ensure the accuracy of the transaction voucher data generated based on the accounts payable data, in one or more embodiments of this specification, step S204 is based on the accounts payable Payment data generates transaction voucher data, including:

Step S204-2, according to the user information of the supplier user included in the accounts payable data, send the account payable data to the terminal device of the corresponding supplier user, so that the supplier user can review the accounts payable data;

In step S204-4, if the approval information sent by the terminal device of the supplier user is received within the preset time period, the transaction voucher data is generated according to the accounts payable data.

Specifically, the second blockchain node sends the received accounts payable data to the terminal device of the supplier user according to the contact information included in the user information of the supplier user, and determines whether the supplier user is received within the preset time period When the judgment result is yes, the transaction voucher data is generated based on the accounts payable data; when the judgment result is no, the transaction failure information is sent to the terminal device of the core enterprise user; where the contact information is as follows Email, supplier user account information on the supply chain finance platform, etc. As a result, by sending the accounts payable data to the supplier user for review, it is reduced that the information included in the accounts payable data is incorrect and the generated transaction voucher data is incorrect, which in turn causes disputes due to the incorrect transaction voucher data. risks of.

Considering that some supplier users use the accounts to conduct illegal transactions after receiving the accounts provided by the core enterprise users. In order to avoid this phenomenon, in one or more embodiments of this specification, as shown in Figure 10, Step S208 executes corresponding transaction operations according to the transaction request, including:

The second smart contract is called, and based on the second smart contract, it is determined whether the transaction data included in the transaction request meets the transaction rules of the transaction voucher data; if the transaction data meets the transaction rules of the transaction voucher data, the corresponding transaction operation is performed according to the transaction data.

The transaction data includes, but is not limited to, the amount of the transaction account, the user information and bank account information of the user who transfers the transaction account, and the user information and bank account information of the user who transfers the transaction account. As an example, when a transaction request is used to request an account transfer (such as a transfer out) operation, the amount of the account to be transferred included in the transaction data is used to transfer the account to be transferred from the bank account information of the outgoing user. Transfer out from the bank account and transfer to the bank account corresponding to the bank account information of the transfer-in user.

The foregoing describes specific embodiments of this specification. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps described in the claims may be performed in a different order than in the embodiments and still achieve desired results. In addition, the processes depicted in the drawings do not necessarily require the specific order or sequential order shown in order to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

In the 1930s, the improvement of a technology can be clearly distinguished between hardware improvements (for example, improvements in circuit structures such as diodes, transistors, switches, etc.) and software improvements (improvements in method flow). However, with the development of technology, the improvement of many methods and processes of today can be regarded as a direct improvement of the hardware circuit structure. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by the hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (such as a Field Programmable Gate Array (Field Programmable Gate Array, FPGA)) is such an integrated circuit whose logic function is determined by the user's programming of the device. It is programmed by the designer to "integrate" a digital system on a PLD, without requiring the chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly realized with "logic compiler" software, which is similar to the software compiler used in program development and writing, but before compilation The original code must also be written in a specific programming language, which is called Hardware Description Language (HDL), and there is not only one type of HDL, but many types, 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), etc., currently most commonly used It is VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that only a little logic programming of the method flow in the above-mentioned hardware description languages and programming into an integrated circuit can easily obtain the hardware circuit that implements the logic method flow.

For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program codes (such as software or firmware) executable by the (micro)processor. , Logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers and embedded microcontrollers.

Therefore, such a controller can be regarded as a hardware component, and the devices included in it for realizing various functions can also be regarded as a structure within the hardware component.
