Fig. 1 illustrates an exemplary system architecture 100 of a method for processing data or an apparatus for processing data to which embodiments of the present disclosure may be applied.
As shown in fig. 1, system architecture 100 may include terminal devices 101, 102, 103, network 104, and block link point 105. Network 104 is the medium used to provide communication links between terminal devices 101, 102, 103 and block link point 105.

The blockchain nodes 105 may be implemented as a distributed cluster of servers that provide various data processing services, or may be implemented as a single server. For example, for a received data access request, the server acquires the blockchain data and performs visualization processing on the acquired blockchain data. The blockchain node 105 may receive data access requests sent by the terminal devices 101, 102, 103. The data access request comprises access requirement information of the blockchain data, and the access requirement information comprises first operation type information.

It should be understood that the number of terminal devices, networks, and block link points in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and block link points, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for processing data in accordance with the present disclosure is shown. The method for processing data comprises the following steps:
In the present embodiment, an execution subject (e.g., block link point 105 shown in fig. 1) of the method for processing data may receive a data access request transmitted by a first terminal through a network. The first terminal may be various terminals that transmit a data access request to the execution main body. As an example, the first terminal may be a mobile phone, a PC, or the like.
The data access request may include, but is not limited to, access requirement information, and the access requirement information may include, but is not limited to, first operation type information. In addition, the access demand information may further include account information, start time information (e.g., 11 am on 5/1/2019), end time information (e.g., 1 pm on 5/1/2019), and the like.
The first operation type information is generally information for characterizing a type corresponding to an operation. As an example, the first operation type information may be "1100" for characterizing that the type corresponding to the operation is a deposit operation type under the application of the financial field. As another example, the first operation type information may also be "Financial-pay" and is used to characterize that the type corresponding to the operation is a deposit operation type in the application of the Financial field.
Among them, a blockchain intelligent contract (Smart contract) is typically a computer protocol in a blockchain that is intended to propagate, verify, or execute contracts in an informational manner. The essence of a blockchain intelligent contract is a set of commitments (commitments) defined in digital form, including agreements on which contract participants can execute these commitments.
In this embodiment, the above-mentioned blockchain data processing rule is generally a processing manner conforming to a protocol in an intelligent contract and used for implementing visualization of data. The above-mentioned blockchain data processing rules may be set by a technician according to experience or requirements of an application scenario. Wherein, a block chain data processing rule corresponds to a processing mode. As an example, the above block chain data processing rule may be "a-B", which means that the a processing procedure is performed on data and then the B processing procedure is performed.
In this embodiment, the blockchain data in the previously stored blockchain data set is usually stored according to a predetermined storage format when being stored. For example, the storage is performed by account number, storage time, and the like. Therefore, the execution subject may acquire the blockchain data corresponding to the access requirement information from the previously stored blockchain data set by using the acquired access requirement information. In addition, a plurality of blockchain data processing rules may be stored in the execution body in advance, and each blockchain data processing rule corresponds to one operation type information. In this way, the execution body may find the blockchain data processing rule corresponding to the first operation type information from the plurality of blockchain data processing rules stored in advance using the acquired first operation type information from the first terminal.
And 203, performing visualization processing on the acquired block chain data based on the block chain data processing rule to obtain visual block chain data.
In this embodiment, the execution subject may perform visualization processing on the acquired blockchain data by using the acquired blockchain data processing rule for implementing visualization of the data, so as to obtain the visual blockchain data.
Here, the above-mentioned visible block chain data may be data that is easy for computer presentation. And the format of the visible area block chain data can be set according to the requirements of practical application scenes. As an example, the above-mentioned visible region block chain data may be Hyper Text Markup Language (HTML) Format data, Portable Document Format (PDF) Format data, WORD Format data, EXCEL Format data, or the like.
In this embodiment, the execution main body may send the visible block chain data to the first terminal through a network. In this way, the first terminal may render the received visual blockchain data directly.
It should be noted that, since the data stored on the block chain has non-tamper-ability, the present disclosure stores the block chain data processing rule for performing visualization processing on the block chain data in the block chain, which can ensure that the stored block chain data processing rule is always safe and reliable. In addition, the stored blockchain data processing rules are adopted to perform visualization processing on the blockchain data, and the processed visual blockchain data are sent to the first terminal, so that the result pushed to the user for presentation can be always the same for any user as long as the input access requirement information is the same. Therefore, the method and the device can avoid the situation that in the prior art, different users process the same data by adopting different processing rules to obtain different presentation results, so that the fact is confused, and the accuracy of the presentation results is favorably ensured.
In an alternative implementation manner of each embodiment of the present disclosure, if the blockchain data processing rule includes a data parsing rule and a data presentation rule. Then, the performing visualization processing on the acquired blockchain data based on the blockchain data processing rule to obtain visual blockchain data may include: and analyzing the acquired block chain data by adopting a data analysis rule, and presenting the analyzed data by adopting a data presentation rule to obtain the visual block chain data.
Here, the execution body may first parse the acquired blockchain data by using the data parsing rule to extract the content at the preset position from the acquired blockchain data. As an example, the preset position may be a field preset by a technician, or may be a preset bit. And then, adding the content obtained by analysis to the corresponding position of a preset template by adopting the data presentation rule so as to realize presentation processing on the analyzed data and obtain the visual block chain data.
The execution main body may be pre-stored with a plurality of preset templates for presenting the block chain data, and each preset template may uniquely correspond to one data presentation rule. The preset template typically includes a presentation format of the data and at least one variable for presenting the data. As an example, the preset template may be a preset HTML template, where the HTML template includes a presentation format of data, such as a spreadsheet format, and at least one variable for presenting data, for example, a first variable for presenting a value of an account, a second variable for presenting a value of a name, a third variable for presenting a value of an account balance, and the like.
More specifically, for example, if the execution body adopts a data parsing rule to extract the contents of the a field and the contents of the B field in the blockchain data. The execution body may take the contents of the extracted a field as a value of a first variable of a preset template and the contents of the extracted B field as a value of a second variable of the preset template. In this way, an assigned template can be obtained. At this time, the assigned template is the visible blockchain data.
In this implementation manner, the content at the preset position in the blockchain data is extracted by using the data analysis rule, and then the extracted content is used as the value of the variable of the template corresponding to the data presentation rule of the blockchain data, so as to obtain the visual blockchain data. Because the template is a pre-edited script program, the visual block chain data is obtained by directly assigning the extracted content to the variable in the template, the visual block chain data can be rapidly obtained, and the data processing time is saved.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario 300 of the method for processing data according to the present embodiment. In the application scenario of fig. 3, a user 301 sends a data access request to a blockchain node 303 through a terminal 302. At this time, the data access request may be: the AA account transfers data from 11 am on month 1 of 2019 to 3 pm on month 2 of 2019. The access requirement information may be: AA account number 2019050111 and 2019050215, transfer type. And the first operation type information may be: the type of transfer.
The blockchain node 303 may perform the following operations:
first, the blockchain node 303 may receive the data access request described above.
Then, the block link point 303 acquires the block chain data corresponding to the access requirement information from the previously stored block chain data set Q. Wherein, the blockchain data set Q is: { (2019050116, AA account transfers M-ary to BB account), (2019050118, withdraw N-ary from AA account), (2019050118, withdraw P-ary from CC account) }. The blockchain data obtained at this time are: (2019050116, AA account transfers M-dollars to BB account) and (2019050118, withdraws N-dollars from AA account). In addition, blockchain node 303 may retrieve a prestored blockchain data processing rule R corresponding to the transfer type.
Then, the blockchain node 303 may perform visualization processing on the acquired blockchain data by using the blockchain data processing rule R to obtain visible blockchain data.
Finally, the blockchain node 303 may send the visible blockchain data to the terminal 302. In this way, terminal 302 can present visual blockchain data to user 301.
The method for processing data provided by the above embodiment of the present disclosure may receive a data access request sent by a first terminal. The data access request comprises access requirement information of the blockchain data, and the access requirement information comprises first operation type information. Then, from the pre-stored blockchain data set, obtaining blockchain data corresponding to the access requirement information, and obtaining pre-stored blockchain data processing rules corresponding to the first operation type information, wherein the blockchain data processing rules are determined based on the blockchain intelligent contract. And then, performing visualization processing on the acquired block chain data based on the block chain data processing rule to obtain visual block chain data. And finally, sending the visual blockchain data to the first terminal so that the first terminal presents the visual blockchain data. In the method of this embodiment, the blockchain data processing rule for performing the visual processing on the blockchain data is stored in the blockchain, so that the blockchain data is visually processed by using the stored blockchain data processing rule on the blockchain, and the visual blockchain data which is easily understood by the user and accurate and reliable after being processed is presented to the terminal where the user is located.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a method for processing data is shown. The flow 400 of the method for processing data includes the steps of:
step 401, receiving a data access request sent by a first terminal, where the data access request includes access requirement information for blockchain data, and the access requirement information includes first operation type information.
Step 402, obtaining the blockchain data corresponding to the access requirement information from the pre-stored blockchain data set, and obtaining the pre-stored blockchain data processing rule corresponding to the first operation type information.
Wherein the blockchain data processing rule is determined based on a blockchain intelligence contract.
Step 404, sending the visual blockchain data to the first terminal, so that the first terminal presents the visual blockchain data.
In the present embodiment, the specific operations of steps 401 and 404 are substantially the same as the operations of steps 201 and 204 in the embodiment shown in fig. 2, and are not repeated herein.
In an optional implementation manner of each embodiment of the present disclosure, the blockchain data in the pre-stored blockchain data set is stored through a data storage step. Wherein the data storage step comprises:
Here, the execution main body may receive a data storage request transmitted by the second terminal through the network. The second terminal may be various terminals that transmit a data storage request to the execution main body. As an example, the second terminal may be a mobile phone, a PC, or the like. The second operation type information is generally information for characterizing a type to which the operation corresponds. The data description information of the data to be stored is generally information for characterizing field names of respective fields of the data to be stored. As an example, the data description information may include "123" for characterizing that the name of the field is an account number. The data description information may also include an "account number" for characterizing the name of the field as the account number.
Step 4022, searching preset operation type information matched with the second operation type information from the preset information pair set. Wherein the information pairs in the set of information pairs include: and corresponding preset description information and preset operation type information.
Here, each information pair in the information pair set includes one preset description information and one preset operation type information. Therefore, the execution subject may search for the preset operation type information matching the second operation type information from the preset information pair set by using the received second operation type information. The preset description information is generally information preset by a technician to describe a name of at least one field. The preset operation type information is generally information preset by a technician for characterizing a type corresponding to an operation.
Here, the execution main body may compare the searched preset description information with the data description information to determine whether the data description information is included in the searched preset description information.
Here, if the data description information is included in the searched preset description information, associating the data to be stored with the second operation type information, and storing the associated data to be stored and the second operation type information into the block chain data set.
In the implementation mode, whether the data to be stored meets the storage condition is judged by comparing the data description information of the data to be stored with the searched preset description information, and if yes, the data to be stored is stored. In this way, it can be ensured that each blockchain data stored in the blockchain data set satisfies the storage condition. The data to be stored can be uniformly stored conveniently, and the stored block chain data can be extracted conveniently. The efficiency of access to blockchain data in a blockchain data set is facilitated to be improved.
In some optional implementations of this embodiment, if the data description information includes a first field for recording an account and a second field for recording a variation of an account quota corresponding to the account. The storing the data to be stored into the blockchain data set after associating the data to be stored with the second operation type information includes:
firstly, an account corresponding to a first field and the account quota variable corresponding to a second field are extracted from data to be stored.
Here, the data description information corresponds to data to be stored. If the data description information includes a first field for recording an account, the data to be stored includes an account corresponding to the first field. If the data description information comprises a second field used for recording the account amount variation corresponding to the account amount, the data to be stored comprises the account amount variation corresponding to the second field. More specifically, for example, if the data description information includes: the "account" and the "account amount variation" may be obtained by extracting a value of the account corresponding to the "account" from the data to be stored corresponding to the data description information. And the value of the account amount variation corresponding to the account amount variation can be extracted.
Then, in a pre-stored block chain data set, in response to the fact that the format of the extracted account amount variation meets a preset format condition, updating the current amount of the extracted account based on the extracted account amount variation.
Here, the execution subject may determine whether the format of the extracted account amount variation satisfies a preset format condition in combination with a preset format condition. Here, the preset format condition may include, but is not limited to, at least one of: the value of the account amount variation belongs to a preset value interval, for example, belongs to (0, 100.00). The dimension of the account amount variation is a preset dimension, such as a meta.
In this implementation manner, if the data description information includes a first field for recording an account and a second field for recording a variation of an account quota corresponding to the account, it may be determined that the currently stored data to be stored needs to be changed with respect to the current quota of the account. Here, after determining that the data format of the account amount variation satisfies the preset format condition, the executive main body may directly add the account amount variation to the stored current amount corresponding to the account in the blockchain data set to obtain the updated current amount. It should be noted that each account number corresponds to a current quota. Typically, the current credit corresponding to the account number is 0 by default.
It should be noted that the data to be stored and the current amount of the account related to the data to be stored are stored at the same time, which is helpful for conveniently extracting the data to be stored and/or the current amount of the account according to the user requirements.
In some optional implementations of the embodiment, either one of the first operation type information and the second operation type information includes at least one of: the first item: information characterizing a type of application that generated the data storage request. The second term is: information characterizing a type of operation performed at an operation interface of the application.
Here, the first operation type information or the second operation type information may include only the second item, or may include both the first item and the second item. Wherein the types of applications may include, but are not limited to, at least one of: the type of application in the medical field, the type of application in the legal field, and the type of application in the financial field. Wherein, if the type of the application is an application type in the financial field, the type of the operation may include, but is not limited to, at least one of the following: deposit operation type, transfer operation type, payment operation type.
In this implementation, based on the first operation type information, the blockchain data processing rule of the data that satisfies the access requirement information is obtained from the blockchain, and the same visualized blockchain data processing rule is used for processing the data generated by the same operation under the same application. The data processing time can be saved, and the visualization processing efficiency of the data is improved. In addition, the associated second operation type information and the data to be stored are stored in the block chain, so that the data stored in the block chain can be quickly and conveniently extracted based on the operation type information.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for processing data in the present embodiment highlights the storage step of the data to be stored. Therefore, in the scheme described in this embodiment, by comparing the data description information of the data to be stored with the searched preset description information, it is determined whether the data to be stored meets the storage condition, and if so, the data to be stored is stored.
