The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a data query method based on a block chain, a block chain processing device and a data query system. First, a description will be given of a data query system provided in the present invention, as shown in fig. 1, where the data query system includes a blockchain processing device, a database, a blockchain, and a client. The user side can communicate with the blockchain processing device through a network, and the blockchain processing device can communicate with a database, so that data in the database can be acquired. The user terminal may include, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and other devices with display functions. The data query method based on the block chain provided by the invention can be applied to a block chain processing device shown in fig. 1, wherein the block chain processing device is used for acquiring integral data of a target object; and storing the integral data into the intelligent contracts of the blockchain, calling the intelligent contracts according to the target object identification after receiving a first inquiry transaction request which is sent by the user terminal and contains the target object identification, sequencing the integral of the target object by calling a sequencing contract method, and feeding back the integral sequencing result of the target object to the user terminal.
The blockchain-based data query method provided by the invention is described in detail below with reference to the drawings and specific embodiments. As shown in fig. 2 and 5, the blockchain-based data query method according to an embodiment of the present invention includes the following steps:
s10: and acquiring related data of a target object, wherein the related data comprises integral data of an examination item of the target object.
Wherein as an example the target object is a criminal and/or a prison manager in a prison, which may specifically be referred to as a prison policeman, which target object is referred to as all criminals in a prison, and/or all prison manager.
In prisons, in order to effectively manage criminals and/or prison administrators in the prisons, the criminals and/or prison administrators are often given an assessment, and the assessment results, i.e., points, are presented by specific scores. Wherein, the invention is not limited herein to specific examination items and amounts.
For example, for criminals 1, 2, N in prison, assessment items for each criminal may be set, including assessment item a, assessment item B, and assessment item C, which may specifically refer to physical ability assessment, efficiency compliance assessment, work assessment, and the like. And in a preset period, the assessment result of each criminal N can be recorded, so that the scores of different examination items of each criminal N are obtained, and the score data of all criminals are obtained.
For another example, for prison police 1, prison police 2, prison..once, prison police N, each prison police's assessment items may be set, including assessment item E, assessment item F, and assessment item G, which may specifically refer to fitness assessment, punching card assessment, work task assessment, and so forth. Similarly, in a preset period, the assessment result of each prison police N can be recorded, so that the scores of different assessment items of each prison police N are obtained, and the integral data of all the prison police N are obtained.
It should be noted that the above-mentioned target object is a criminal and/or a prison manager, which is only illustrated herein for exemplary purposes, and in some application scenarios, the target object may also specifically refer to the integral data of each prison partition in the prison, which is not limited herein.
The prison system in the prison can record the related data of the target object, and the related data comprise the integral data of the target object and upload the integral data into the prison database in real time. It should be noted that, the related data of the target object also includes other data, which will be further described in the following embodiments, and will not be described here. For a blockchain processing device, relevant data of a target object can be acquired.
S20: and storing the integral data and the target object identification into an intelligent contract of a blockchain in an associated mode, wherein the intelligent contract comprises a sequencing contract method, and the sequencing contract method is used for sequencing the assessment item integral of the target object according to the integral data.
It should be noted that, in the embodiment of the present invention, the smart contract needs to be deployed in the blockchain first, where, based on the data query method provided in the embodiment of the present invention, since the integral data needs to be ordered in the blockchain, the smart contract in the implementation of the present invention is different from the conventional smart contract, and the smart contract in the embodiment of the present invention includes an ordering contract method, where the ordering contract method is used to order the assessment item integral of the target object according to the integral data.
The process of generating and deploying the smart contract will be briefly described.
In an embodiment of the present invention, a deployment scenario is provided, including the following steps:
(1) The intelligent contract developer uses the language which can be compiled into the byte code to compile the intelligent contract source file corresponding to the blockchain, and can understand that the intelligent contract comprises a contract method, in particular a sequencing contract method.
(2) The intelligent contract source file is compiled using a compiler of the intelligent contract source code corresponding development language, and the compiling target is a WASM byte code file, so that an intelligent contract in the form of WASM byte codes (herein called WASM intelligent contract) is obtained. It should be noted that, for convenience of description, the following examples of the WASM intelligent combination are given, but the present invention is not limited thereto.
(3) Through the steps (1) and (2), the WASM intelligent contract which can be deployed in the blockchain database is obtained, and the user side can send an intelligent contract deployment transaction to the blockchain processing device, wherein the intelligent contract deployment transaction comprises deployment transaction parameters, and the deployment transaction parameters comprise contents such as a transaction sender address, signature information of the transaction sender on the deployment transaction, a binary representation form (namely WASM byte codes obtained by encoding in advance) of the WASM intelligent contract, and the like.
(4) After receiving the contract deployment transaction, the blockchain processing device can analyze deployment transaction parameters such as the address of a transaction sender, signature information of the transaction sender on the deployment transaction, a binary representation form (i.e. a WASM byte code file obtained by encoding) of the WASM intelligent contract, and the like, so that the WASM intelligent contract can be deployed in the blockchain subsequently.
(5) The blockchain processing device may deploy the smart contract in the blockchain upon receiving the contract deployment transaction.
After deployment of the smart contract, the point data and target object identification may be associated into the blockchain smart contract. It should be noted that the target object identifier is an identifier for uniquely identifying the target object. For example, when the target object is a criminal, the target object identification may specifically refer to a criminal number or an identity card; when the target object is a prison police, the target object identification may specifically refer to a prison police employee identification number or an identity card. The invention is not particularly limited.
S30: and receiving a first inquiry transaction request sent by a user terminal, wherein the first inquiry transaction request comprises the target object identifier.
After the first query transaction request is used for querying the integral sequencing result of the target object, and the integral data and the target object identification are associated and stored in the intelligent contract of the blockchain, when a user needs to query the integral data of the target object, the integral data of the target object can be searched through the target object identification, specifically, the first query transaction request sent by the user side to the blockchain processing device comprises the target object identification, the blockchain processing device can receive the integral query transaction request, and analyze the integral query transaction request to obtain the target object identification.
S40: and calling the intelligent contract according to the target object identification to call the sequencing contract method to sequence the integral of the target object.
As mentioned above, the ranking contract method is used for ranking the assessment item scores of the target object according to the score data. Thus, by invoking the smart contract, the sort contract method is invoked to perform a related sort of the integral data within the smart contract. The ranking herein may refer to ranking the points of the same assessment item in the target object. Therefore, for each examination item, the corresponding product score ordering result is provided. For example, for assessment item A, the score ranking result for each criminal may be as follows: criminal 1, criminal 2, &..criminal N. For example, for the assessment item E, the score ranking results for each prison police may be as follows: prison police 1, prison police 2, & prison police N.
S50: and feeding back the integral sequencing result of the target object to the user side.
After receiving the point inquiry transaction request sent by the user terminal, the intelligent contract is called according to the target object identification, so that the sorting contract method is called to sort the point data of the target object, the point result is obtained, and finally the point sorting result of the target object is fed back to the user terminal, so that the user can inquire the point inquiry result of any target object at any time through the user terminal.
Therefore, in the data query method based on the blockchain, the integral data of the target object is firstly obtained, then the integral data and the target object identifier are associated and stored in the intelligent contract, only the integral data in the related data of the target object is stored in the intelligent contract, and excessive storage pressure is not given to the intelligent contract, on the other hand, the integral data of the target object is sequenced in the blockchain by creating and calling a sequencing contract method in the intelligent contract, so that an integral sequencing result of the target object is obtained, and finally the integral sequencing result can be fed back to the user side, so that the condition that the read data is not the direct data on the blockchain but is modified and processed is avoided, the reliability of the integral result is improved, the time consumption caused by reading a large amount of integral data is also reduced, and the integral query efficiency is improved.
In an embodiment, the related data of the target object includes attribute data and/or assessment data, where the attribute data refers to attribute data of the target object, and the assessment data refers to specific assessment information of an assessment project, and the assessment record information includes video and photo and data related to assessment. For example, when the target object is a criminal, the attribute data refers to attribute information such as identity, age, past occupation, duration of the seat to be judged, reason of crime, time and place of the crime, and when the target object is a prison police, the attribute data of the early warning refers to information such as employee certificate of the early warning, main responsible work content, work duration, reward and punishment record. In the embodiment of the present invention, in order to provide a more practical query scenario, the processing manner is different from the integration data with respect to the attribute data and/or the assessment data of the target object, which is described in detail below.
Referring to fig. 3, the method further includes the following steps:
s60: and uploading the attribute data and/or the assessment data into a blockchain, and acquiring a transaction hash value corresponding to the attribute data and/or the assessment data.
It will be appreciated that after the relevant data of the target object is obtained, for the score data, the relevant data is processed by the processing logic of steps S10-S50, and for the attribute data and/or the assessment data, the attribute data and/or the assessment data is stored in the transaction, i.e. the attribute data and/or the assessment data is uplink to the blockchain, and the transaction hash value of the transaction in which the attribute data and/or the assessment data is stored is obtained. The process of calculating the transaction hash value is not described in detail herein.
S70: and associating the transaction hash value with the target object identification and storing the transaction hash value and the target object identification into the intelligent contract.
And after obtaining the transaction hash value, associating the transaction hash value with the target object identification and storing the transaction hash value into the intelligent contract. For example, taking criminal 1 as an example, attribute data and/or assessment data of the criminal 1 are stored in a transaction, a transaction hash value is obtained, and then the transaction hash value corresponding to the attribute data and/or the assessment data of the criminal 1 is stored in an intelligent contract in association with the identification of the criminal 1. The treatment is similar for other criminals, or for prison polices, and is not illustrated here.
It will be appreciated that, for attribute data and/or assessment data of a target object, since the number of prisons and/or criminals is high in prison, and the type of data stored in the prison database includes not only integral data, attribute data, but also a relatively large amount of data, the corresponding attribute data and/or assessment data, the data read from the prison database, and many thousands of characters, if all the data were to be linked, when the attribute data of a criminal requiring a query is hundreds of thousands of, the size of the character string being queried may be a very large number, which is very heavy to the load of the network, and the query speed will be very slow. In order to relieve the follow-up query pressure, the scheme needs to firstly uplink attribute data and/or check data corresponding to a target object into a blockchain, acquire transaction hash values corresponding to the attribute data and/or check data, then store the transaction hash values and the target object identification in an intelligent contract, and then quickly query corresponding transaction hash values in the intelligent contract through the target object identification.
S80: and if a second inquiry transaction request which is sent by the user side and contains the target object identification is received, searching the transaction hash value associated with the target object identification from the intelligent contract.
After the transaction hash value is associated with the target object identifier and stored in the intelligent contract, the transaction hash value of the intelligent transaction can be queried at any time. For the user, when the attribute data of a certain target object needs to be queried, a second query request transaction request can be triggered through the user side, wherein the second query request transaction request is used for querying the attribute data and/or the assessment data of the target object. And for the blockchain processing device, if a second inquiry transaction request which is sent by the user terminal and contains the target object identifier is received, the associated transaction hash value is searched according to the target object identifier.
S90: and according to the transaction hash value, the attribute data and/or the assessment data of the target object are read from the blockchain.
S90: and feeding back attribute data and/or assessment data of the target object to the user side.
It will be appreciated that after the transaction hash value associated with the target object identifier is found from the smart contract, the attribute data and/or the assessment data of the target object may be read from the blockchain based on the transaction hash value. For example, taking criminal 1 as an example, when attribute data and/or assessment data of the criminal 1 need to be queried, the attribute data and/or the assessment data of the criminal 1 are read from the blockchain according to the transaction hash value of the attribute data and/or the assessment data of the criminal 1.
In one embodiment, it should be noted that, in order to improve the efficiency of the related data of the target object during the uplink, the process of obtaining the related data of the target object is improved, and specifically, as shown in fig. 4, the method further includes the following steps:
s101: judging whether related data of the criminals and/or prison manager are acquired in the prison database for the first time;
s102: if yes, the prison database is scanned completely so as to acquire relevant data of the criminals and/or prison manager.
And when the data is firstly uploaded and acquired, performing full scanning on the prison database to acquire relevant data of the criminals and/or prison manager.
S103: creating a timing scanner in the prison database, wherein the timing scanner is used for acquiring related data of the newly added criminals and/or prison manager according to a preset polling period and the data identification value of the related data and the recorded cursor value;
s104: and receiving the newly added related data inquired by the timing scanner.
The method comprises the steps of recording a cursor value, wherein the cursor value is used for recording a data identification value of the relevant data which is finally uplink, each time of newly added relevant data in a prison database is provided with a unique corresponding data identification value, and the data identification values of the relevant data in the prison database are sequentially increased according to a time sequence stored in the prison database.
For steps S101-S104, as shown in fig. 5, the overall frame example diagram adopted in the embodiment of the present invention is shown, in the embodiment of the present invention, a trigger is added to a prison database, so that the relevant data of a target object can be captured at a moment when the relevant data appears, and then the newly added data is found by a timing scanner and directly linked. Specifically, the embodiment of the invention uses a record cursor, wherein the record cursor value is used for recording the data identification value of the relevant data which is finally uplink, the relevant data which is newly added each time in the prison database has a unique corresponding data identification value, and the data identification values of the relevant data in the prison database are sequentially increased according to the time sequence stored in the prison database, so that the timing scanner firstly checks the number of the current record cursor records each time when the newly added relevant data is read. For example, if the recorded cursor value is 3 at this time, we start to search from the data with the data identification value of 4, and perform the uplink operation on the extra related data, it can be seen that, since the data identification value of the table of the recorded newly-added data is automatically increased, the data identification value of the newly-added data added each time gradually increases, and when the new-added query is completed in the process of the query, the recorded cursor value is updated to the data identification value of the last newly-added related data, so that the next query can directly start to be uplink from the last data.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
In one embodiment, a blockchain processing device is provided, where the blockchain processing device corresponds to the blockchain processing method in the above embodiment one by one.
