Detailed Description

The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and that no limitation of the invention is intended. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.

Before describing the embodiments of the present invention, a block chain network system implementing the method, apparatus, device and medium for precise poverty alleviation based on block chains according to the embodiments of the present invention will be described. As shown in fig. 1A, the device side participating in the blockchain network system of the embodiment of the present invention includes: a service application server node device 101, a general computing storage device 102, a third party node device 103 and a user's terminal device 104. The service application server node device 101, the third party node device 103, and the user terminal device 104 may be nodes in a blockchain network, or may not be blockchain nodes, but may interact with the blockchain node device through an interface provided by the blockchain node device to participate in the blockchain network. When the terminal device of the user is a node device in the blockchain network, the terminal device is a lightweight node of the blockchain network, wherein the lightweight node can be generally deployed in the terminal device, the requirement on hardware configuration of the device is low, the lightweight node can be integrated on the operating system level to control hardware in the terminal device, and meanwhile, the lightweight node can interact with upper-layer application software to provide blockchain support for the functions of the application software.

For example, as shown in fig. 1B, the implementation procedure of the block chain-based precision poverty-relieving method according to the embodiment of the present invention may be: poor object information (such as identity information of poor objects) of the mobile phone; in order to ensure the accuracy and traceability of poor object information, a block link node sends an information uplink request; behavior data of poverty-stricken objects are obtained by different third-party nodes (namely education nodes, medical nodes, financial institution nodes and credit institution nodes) and processed, so that a real and credible poverty-stricken population real database is established to serve different poverty-stricken scenes, such as poverty-stricken education authentication scenes, poverty-stricken population supporting scenes and other scenes. It should be noted that, in the embodiment of the present invention, the method for precisely poverty alleviation based on the block chain may be executed by taking the service application server node device 101 in fig. 1A as an executing party, and performing interactive execution with the third party node device 103 and the terminal device 104 of the user, as in the following first embodiment and second embodiment. Or may be performed interactively by the node of the blockchain node (i.e., the current block generation node) in fig. 1A, with the third-party node 103 and the terminal device 104 of the user, as in the following third and fourth embodiments. Although the block chain-based precision poverty-relieving method implementing the embodiment of the present invention may be performed differently, the idea of implementing a specific precision poverty-relieving method is the same. The technical solution of the embodiment of the present invention is introduced based on the above-described blockchain network system.

Example one

Fig. 2 is a flowchart of an accurate poverty alleviation method based on a block chain according to an embodiment of the present invention, which is applicable to a situation where poverty-handicapped object behavior data is processed based on a block chain technology. The method can be executed by the block chain-based precision poverty-relieving device configured on the business application server provided by the embodiment of the invention. The apparatus may be implemented in hardware and/or software. The service application server may be a node device providing the poverty-alleviation service application service in the blockchain network, and may be a blockchain link point or not, but may interact with the blockchain link point through an interface provided by the blockchain node to participate in the blockchain network.

As shown in fig. 2, the method specifically includes the following steps:

s201, acquiring poverty object behavior data.

The poverty-stricken object may be an object meeting the condition of the poverty-stricken item, for example, if the poverty-stricken item is a poverty-stricken learning-aid item, the poverty-stricken object may be a student with a poor family condition. The poverty-handicapped object can be an object which is applied by the user through an application program client installed on the terminal device according to the specific content of the poverty-handicapped item and by combining the situation of the user. The poverty-stricken subject behavior data may be behavior data that can characterize the poverty-stricken subject's family condition, poverty of poverty, etc. in various aspects of life, and may include, for example, but is not limited to: educational behavior data, visit behavior data, account flow information, and credit data, among others. The educational behavior data can be specific situation data of the poverty-poor object in education, and can include but is not limited to: the current education stage (such as nine-year compulsory education, high school, university, and the like), the school achievement, the school of employment, the grade of the current year, and the like. The visit behavior data may be specific medical data of the impoverished subject, and may include but is not limited to: the time of illness, the name of the illness, the treatment, the hospital, the cost of the treatment paid, etc. The account running information may be specific data of poor subjects in terms of income and expenditure, and may include but is not limited to: the poor objects and the detailed data (such as inflow and outflow time of each fund, inflow and outflow accounts, remark information and the like) of the balance of all bank accounts of the family members in a preset time period (such as one year). The credit data can be the specific situation data of the poverty-poor object in terms of credit keeping, and can include but is not limited to credit situation data of financial institutions or enterprises (such as whether the financial institutions or enterprises are loaned or not, loan amount, whether the financial institutions or enterprises pay on time or not, and the like), whether related behaviors violating credit exist in daily life or not, and the like.

Optionally, in the embodiment of the present invention, the triggering condition for the service application server to obtain the behavior data of the poor object may be that, when a user applies for the poor item, the user is triggered to serve as the poor object, and the behavior data of the poor object is obtained until the poor item is applied. Or after the application time of the poverty alleviation project is over, triggering all users applying the poverty alleviation project to be used as poverty alleviation objects, acquiring behavior data of the poverty alleviation objects and the like.

Optionally, in the embodiment of the present invention, there are many ways to obtain behavior data of the poverty-stricken object, which may be: if the user applies for the name of the poverty-poor object to the business application server, the related behavior data information is uploaded to the business application server according to the poverty-poor project application requirement, and at the moment, the server can directly acquire the behavior data uploaded by the user as the poverty-poor object behavior data of the user (namely the poverty-poor object). For example, if the poverty relief item is a poverty relief learning aid item, when the user applies for the nominal amount of the poverty relief object to the business application server, the education behavior data, the account flow information, the credit data, and the like of the user may be uploaded to the business application server according to the application requirement of the poverty relief learning aid item, and at this time, the business application server may directly acquire the education behavior data, the account flow information, and the credit data uploaded by the user as the poverty relief object behavior data of the user (i.e., the poverty relief object).

Optionally, the business application server may obtain the behavior data of the poor object by interacting with a third-party node. The third-party node may be a node of a different department, institution or enterprise providing behavior data of the poverty-stricken object, and optionally, the third-party node may include one or more of an education node (e.g., a node device corresponding to an education institution providing the education behavior data, such as a school, an education office, etc.), a medical node (e.g., a node device corresponding to a medical structure providing the visit behavior data, such as a hospital, a health office, etc.), a financial institution node (e.g., a node device corresponding to a financial institution providing account flow information, such as a bank, a transaction center, etc.), and a credit institution node (e.g., a node device corresponding to a credit institution providing credit data, such as a bank, a credit company, etc.), and the like. Each third-party node may be a block link point or not, but may participate in the block chain by interacting with the block link point. Optionally, the behavior data corresponding to the third party node may be stored in a local database of the third party node device, or may be stored in a poor object behavior data block chain.

When the business application server obtains the behavior data of the poor object through the third-party node, because the behavior data of the poor object corresponding to different poor objects are different, when the behavior data of the poor object of each poor object is to be accurately obtained, the behavior data of the poor object corresponding to the identity information (namely, the identity information, such as at least one of the fingerprint feature, the face image feature, the age, the gender and the region of the poor object) of each poor object can be interacted with the third-party node, the obtained identity information of the poor object is sent to the third-party node, and the third-party node searches the behavior data of the poor object corresponding to the identity information according to the received identity information of the poor object and feeds the data back to the business application server. Specifically, when the business application server obtains the behavior data of the poor object through the third-party node, at least one of the following items may be included:

1) acquiring poverty object education behavior data sent by education nodes;

2) acquiring the visit behavior data of the poverty-stricken object sent by the medical node and/or the visit behavior data of a poverty-stricken family to which the poverty-stricken object belongs;

3) acquiring running information of the poor object account sent by the financial institution node;

4) acquiring poor object credit data sent by a credit agency node;

illustratively, taking the obtaining of the educational behavior data as an example, the business application server interacts with the educational node, and may send the identity information of the poor object to the educational node, and the educational node searches the educational behavior data corresponding to the identity information of the poor object from the local database or the block chain of the behavior data of the poor object according to the received identity information of the poor object, and feeds back the educational behavior data to the business application server.

Optionally, if the poor object behavior data is stored in a local database of each third-party node or behavior data uploaded by the poor object, the business application server obtains specific data information which may be the poor object behavior data; if the poor object behavior data is the behavior data stored in the block chain, the business application server may first obtain a storage address of the poor object behavior data from the third-party node, and then obtain the corresponding poor object behavior data from the block chain through the storage address.

And S202, processing according to the poverty-stricken object behavior data.

Optionally, when the business application server processes the poor object behavior data according to the poor object behavior data, the obtained poor object behavior data may be processed based on a processing rule specified in an intelligent contract of the blockchain network, where the intelligent contract of the blockchain network may be a set of digitally defined commitments created when constructing a blockchain network for accurate poverty relief, where the commitments include a processing rule for processing the poor object behavior data by each node of the blockchain. It may be stored in a block chain, such as in a founder block of the block chain; or may be stored locally at the blockchain node. Therefore, when the business application server processes the poor object behavior data according to the intelligent contract, the business application server may first obtain the intelligent contract from the block chain or the local area, and then execute the processing operation on the poor object behavior data according to the obtained intelligent contract.

Specifically, there may be many processing rules for the poor object behavior data specified in the smart contract, and this embodiment is not limited to this. The acquired poor object behavior data can be subjected to accuracy verification processing. If the authority of the third-party node providing the poor object behavior data is limited, comparing the signature of the third-party node with the authorized node signature list in the intelligent contract, and if the signature of the third-party node exists, the authority of the third-party node is successfully verified, namely the accuracy of the acquired poor object behavior data is successfully verified. The acquired poor object behavior Data may also be encrypted, for example, the acquired poor object behavior Data may be encrypted according to an Encryption algorithm (such as a public-private key Encryption algorithm, a Data Encryption Standard (DES) algorithm, an Advanced Encryption Standard (AES) algorithm, a hash Encryption algorithm, and the like) agreed in an intelligent contract, so that the security of the acquired poor object behavior Data is ensured, and the poor object behavior Data is prevented from being leaked or tampered. The obtained behavior data of the poverty-handicapped object may also be subjected to screening processing, for example, according to a screening method specified in an intelligent contract, according to the obtained behavior data of the poverty-handicapped object, the poverty-handicapped object which does not meet the application condition is removed, or the poverty-handicapped object with the poverty-handicapped degree ranked in the top preset number (which may be determined according to the number of poverty-handicapped objects subsidized by the poverty-handicapped project plan) is screened, and the specific screening method will be described in detail in the following embodiments.

When the service application server processes the acquired poor object behavior data based on the processing rule specified in the intelligent contract of the block chain network, the service application server may process the poor object behavior data by using one processing rule specified in the intelligent contract, or may process the poor object behavior data by using a combination of a plurality of processing rules specified in the intelligent contract. This is not limitative.

S203, according to the poor object behavior data and/or the processing result, generating an on-chain transaction processing request, and sending the on-chain transaction processing request to the block chain network.

Optionally, the on-chain transaction processing request may be an uplink storage request generated by the service application server according to the poor object behavior data and/or the processing result, and may instruct the blockchain node to perform an operation of writing data included in the on-chain transaction processing request into the blockchain. Specifically, a data uplink storage request including poor object behavior data and/or a processing result may be directly generated according to the poor object behavior data and/or the processing result, and sent to the blockchain network, so that a node in the blockchain network writes the poor object behavior data and/or the processing result into the blockchain. Further processing may be performed according to the behavior data and/or the processing result of the poor object, and then generating a data uplink storage request including a further processing result, for example, generating an uplink transaction request according to the processing result, including: determining a target poverty-relief object and a poverty-relief amount of the target poverty-relief object according to the processing result and the obtained target poverty-relief condition; an uplink storage request is generated that includes the target poverty-poor object and the poverty-leaner limit for the target poverty-poor object.

Optionally, the on-chain transaction processing request in the embodiment of the present invention may also be a transaction processing request that is generated by the service application server according to the poor object behavior data and/or the processing result, and that may instruct the block chain node to perform operations such as screening, verification, modification, deletion, and the like according to the data contained therein. For example, if the processing according to the poor object behavior data in S202 is to verify only the accuracy of the behavior data, and the function of the on-chain transaction request to be generated at this time is to screen the poor object, an on-chain data screening request including the poor object behavior data may be generated according to the poor object behavior data and sent to the block chain network, so that the node in the block chain network screens the poor object according to the poor object behavior data in the received on-chain data screening request and the screening rule specified in the intelligent contract of the block chain network, and writes the screening result as the transaction data into the block chain.

According to the accurate poverty alleviation method based on the block chain, poverty alleviation object behavior data is obtained and processed, a chain transaction processing request is generated according to the poverty alleviation object behavior data and/or a processing result, the chain transaction processing request is sent to the block chain network, nodes in the block chain network perform related processing, and the processing result is written into the block chain as transaction data. Through the process of realizing accurate poverty alleviation based on the block chain, the situation that poverty alleviation object information is tampered is avoided, the openness and reliability of processing poverty alleviation object information are ensured, and the credibility of accurate poverty alleviation is improved.

Example two

Fig. 3 is a flowchart of a precise poverty-relieving method based on a block chain according to a second embodiment of the present invention. The embodiment is further optimized on the basis of the above embodiments, and specifically, a preferred example of the block chain-based precise poverty-relieving method performed by the service application server is given. Referring to fig. 3, the method specifically includes:

s301, acquiring identity information of the poor object from the block chain.

The identity information of the poor object may be related information representing a unique identity of the poor object, which is entered by an application client installed on a terminal device of the poor object when the poor object applies for a poor object qualification of the poor item, such as at least one of fingerprint features, facial image features, age, gender and territory of the poor object, but not limited to these. The identity information of each poverty poor object is not the same. In order to ensure the security of the identity information of the poor object, the identity information entered by the poor object through the application client may be stored in the blockchain. For example, the application client generates a chain storage request including the poor object identity information according to the poor object identity information received and entered, and sends the chain storage request to the block chain network, so that the block chain node receives and responds to the chain storage request, and writes the poor object identity information contained in the chain storage request into the block chain.

For example, when the service application server needs to obtain identity information of the poor object from the block chain, an identity information query request of the poor object may be generated first and sent to the block chain network, so that the current block generation node of the block chain queries the identity information of the poor object according to the query request and feeds the query information back to the service application server. Optionally, the identity information of the poor object fed back to the service application server by the current block generation node of the block chain may be specific identity information data of the poor object, or may be a storage address of the identity information of the poor object in the block chain, and the service application server obtains the identity information of the poor object from the block chain network according to the storage address of the identity information of the poor object fed back by the current block generation node.

Optionally, if the identity information of the poor object is entered into the service application server through the application client installed on the terminal device of the poor object, the service application server may also directly obtain the identity information of the poor object from its local location at this time.

And S302, acquiring poverty object behavior data.

For example, when the business application server obtains the poor object behavior data, the business application server may obtain the poor object behavior data corresponding to the identity information of the poor object according to the identity information of the poor object obtained in S301. For example, the method may be that the method interacts with a third-party node, identity information of an object to be poverty is sent to the third-party node, and the third-party node searches poverty object behavior data corresponding to the identity information of the poverty object from a block chain or a local database according to the received identity information of the poverty object, and feeds the poverty object behavior data back to the service application server. Or interacting with a third-party node, sending an on-chain data query request containing identity information of the poor object to the third node, receiving and responding to the on-chain data query request by the third-party node, searching poor object behavior data corresponding to the identity information of the poor object from a block chain or a local database, generating an on-chain transaction processing request according to the found poor object behavior data, feeding back the transaction processing request to the current block generating node, receiving and responding to the on-chain transaction processing request by the current block generating node, obtaining poor object behavior data from the transaction processing request, and performing the following operation of screening the poor object.

And S303, screening the poor objects according to the poor object behavior data.

Optionally, the poverty-deficient objects in S301 and S302 are poverty-deficient objects initially applied (i.e., the users apply themselves when considering that they satisfy the application condition), so that the respective poverty degrees of all the initially applied poverty-deficient objects are different, and the data of the poverty-deficient objects that can be subsidized by poverty-deficient projects is limited. Specifically, the application condition of the poverty alleviation project may be obtained from the block chain intelligent contract, and the poverty alleviation object behavior data may be screened according to the obtained application condition and the poverty alleviation object behavior data. For example, if the application conditions of the poverty-alleviation project are as follows: college students and their family income is within 1 ten thousand of money. At the moment, the education behavior data and the poor object account running water information in the poor object behavior data are screened according to the application condition of the poverty alleviation project, the poor objects corresponding to the poor behavior data which do not meet the application condition are eliminated, and the precision of poverty alleviation is guaranteed.

Optionally, in order to ensure the openness and traceability of screening poor objects, an uplink storage request including the screening result may be generated according to the screening result of screening poor objects, and sent to the block chain network, so that the block chain node writes the screening result into the block chain.

S304, determining the poverty type of the poverty-poor object according to the screened poverty-poor object behavior data.

For example, when determining the poverty type of the poverty object according to the screened poverty object behavior data, an intelligent contract may be obtained from a block chain or locally, and the poverty type of each poverty object may be determined according to the poverty object behavior data of the screened poverty object according to poverty type determination rules specified in the intelligent contract.

The poverty type determination rule may be a specific rule for determining the poverty type according to the poverty degree value of each poverty object, for example, different poverty degree ranges may be set for different poverty types, for example, the poverty degree above 90 points may be set as a poverty type, the poverty degree above 70-89 points may be set as a poverty type, the poverty degree below 50 points may be set as a general poverty type, and the poverty degree below 50 points may be set as a non-poverty type.

Optionally, to determine the poverty type of the poverty-poor object, the poverty degree value of each poverty-poor object is determined according to the poverty-poor object behavior data of each poverty-poor object. Specifically, when determining the poverty degree value of the poverty-poor object, a poverty-poor scoring rule corresponding to each type may be set in advance according to the type of the poverty-poor object behavior data (taking the poverty-poor object account running information as an example, the poverty-poor scoring rule may be set according to the annual income, if the annual income recorded in the poverty-poor object account running information is more than 5 ten thousand, the poverty-poor scoring is 0, if the annual income is between 3 and 5 ten thousand, the yearly income is 3, if the annual income is between 1 and 3 ten thousand, the yearly income is 9, and if the annual income is less than 1 ten thousand, the yearly scoring is 10), scoring the acquired poverty-poor object behavior data of each type according to preset poverty-poor scoring rules of each type of behavior data, and then determining the total poverty degree score of the poverty-stricken object behavior data according to the grading result of each type of poverty-stricken object behavior data. Optionally, when determining the total poverty degree score of the poverty-poor object behavior data according to the scoring result of each type of poverty-poor object behavior data, summing the scores of the poverty-poor object behavior data of each type to obtain the total poverty degree score; or setting different weight values for each type, and calculating the weighted total score of the behavior data of each type of poverty-deficient object as the total score of poverty-deficient degree.

Optionally, when determining the total score of the poverty degree of the poverty-stricken object behavior data, the total score of the poverty degree of the poverty-stricken object behavior data obtained in S302 may be evaluated by using a pre-trained poverty degree analysis model. Specifically, the acquired poverty-poor object behavior data may be input into a trained poverty-poor degree analysis model, and the model may process the input poverty-poor object behavior data based on an algorithm and sample data during training and output a total poverty-poor degree score of each poverty-poor object behavior data. The poverty degree analysis model may be a machine learning model based on a Neural network, and the adopted algorithms may include Deep Neural Networks (DNNs), Recurrent Neural Networks (RNNs), Long-Short Term Memory (LSTM) Networks, threshold cycle units, simple cycle units, auto-encoders, decision trees, random forests, feature mean classifications, classification regression trees, hidden markov, K-nearest neighbor (KNN) algorithms, logistic regression models, bayesian models, gaussian models, and KL divergences (Kullback-Leibler), and the like. Optionally, the large amount of sample data for training the poverty level analysis model may include: and behavior data of a large number of poverty-stricken objects and the poverty-stricken degree total score corresponding to the behavior data. And training the preset initial model by adopting a large number of training samples to finally obtain a poverty degree analysis model for determining a poverty degree total score of the poverty degree of the poverty object behavior data according to the behavior data of the poverty object.

Optionally, after determining the poverty degree of each poverty-poor object, determining the poverty type of the poverty-poor object according to a poverty type determination rule. Specifically, the poverty degree of each poverty-poor object may be matched with a poverty degree range value corresponding to each poverty type in the poverty type determination rule, and then the poverty type to which each poverty-poor object belongs may be determined, for example, if the poverty degree of a certain poverty-poor object is 95 points, and the poverty type determination rule specifies that the poverty degree is set as the poverty type above 90 points, the poverty type of the poverty-poor object may be determined as the poverty type.

S305, determining a target poverty-relief object and a poverty-relief amount of the target poverty-relief object according to the processing result and the obtained target poverty-relief condition.

The processing result may be the poverty type of each poverty object determined in S304. The target poverty alleviation condition may be a judgment criterion that is specified in the poverty alleviation item and can be supported by the poverty alleviation item, for example, which poverty alleviation types can be specifically used as poverty alleviation objects supported by the poverty alleviation item. The condition of dividing the lean-right amount can be further included, for example, whether the lean-right amount is distributed once or multiple times; the poverty relief payment is equally divided by each poverty relief object, or the poverty relief payment with different amounts is issued to different poverty relief objects according to poverty relief grades, and the like.

Specifically, when the target poverty alleviation object and the poverty alleviation amount of the target poverty alleviation object are determined according to the processing result and the obtained target poverty alleviation condition, the poverty alleviation type of each poverty alleviation object determined in step S304 may be matched with the target poverty alleviation type in the target poverty alleviation condition to determine the target poverty alleviation object. The target poverty alleviation type can be a poverty alleviation type representing the support of the poverty alleviation item, for example, the target poverty alleviation type is a poverty alleviation type.

Optionally, in this embodiment, the process of screening the poor objects by the current block generation node according to the poor object behavior data may be the same as the process of screening the poor objects by the service application server according to the poor object behavior data in the foregoing embodiments, which is not described in detail herein.

In order to ensure transparency and fairness of screening operations on poor objects, screening results corresponding to the screening operations on the poor objects can be written into a block as transaction data after the poor objects are screened, and optionally, node identifiers of current block generation nodes can be written into the block at the same time when the screening results are written into the block.

Example four

Fig. 5 is a flowchart of a precise poverty-relieving method based on a block chain according to a fourth embodiment of the present invention. The present embodiment is further optimized based on the above embodiments, and specifically, a preferred example of the block chain-based precision poverty-relieving method performed by the block link points is given. Referring to fig. 5, the method specifically includes:

s501, receiving an uplink storage request comprising identity information of a poor object, and writing the identity information of the poor object into a block as transaction data;

wherein the identity information of the poor object comprises at least one of fingerprint characteristics, facial image characteristics, age, gender and territory of the poor object.

Optionally, the identity information of the poor object may be identity information entered by the poor object through an application client installed on the terminal device of the poor object, and in order to ensure the security of the identity information of the poor object, the identity information entered by the poor object through the application client may be stored in the blockchain. For example, the application client generates a chain storage request including the identity information of the poor object according to the received and input identity information of the poor object, and sends the chain storage request to the block chain network, and the current block generation node of the time zone block chain network receives and responds to the chain storage request, acquires the identity information of the poor object, and writes the acquired identity information of the poor object as transaction data into the block.

Optionally, in this embodiment, the receiving an uplink storage request including identity information of the poor object includes:

if the terminal equipment generating the uplink storage request including the poor object identity information is not the node equipment in the blockchain network, the current block generating node receives the uplink storage request including the poor object identity information, wherein the uplink storage request includes the poor object identity information, and the terminal equipment of the user interacts with the node equipment in the blockchain network.

If the terminal equipment generating the uplink storage request comprising the identity information of the poor object is a lightweight node in a block chain network, the current block generating node receives a network interaction interface of the lightweight node configured in the terminal equipment and transmits the uplink storage request comprising the identity information of the poor object; and the identity information of the poor object is obtained by the terminal equipment through data interaction with an application program client through an upper-layer interaction interface of the lightweight node. The light-weight node in the terminal equipment provides an upper-layer interactive interface for carrying out interaction on the identity information of the poor object with the application program client through the upper-layer interactive interface, so that the identity information of the poor object is obtained. The lightweight node can realize functions through software and is integrated in an operating system. The upper layer interactive interface can be an interface for the lightweight node to directly interact with the client, and can also be an interface configured through an operating system. The upper-layer interactive interface can acquire poor object identity information from the application program client. Illustratively, the client interaction data may be the identity information of the poor object entered by the application client receiving the user. The lightweight node configured at the terminal equipment also provides a network interactive interface, and is used for performing data interaction with other block chain nodes in the block chain network through the network interactive interface to send uplink transaction requests including poor object identity information. It should be noted that the lightweight node may be loaded in an operating system of the terminal device, so as to directly drive hardware, such as a CPU, a storage device, a network communication device, and the like, through a driver of the terminal device to implement a corresponding function; the lightweight node can also be installed in the terminal equipment as an independent third-party application program, and the corresponding function is realized through the operation of the third-party application program.

And S502, sending identity information of the poor object to a third-party node.

For example, after obtaining identity information of the poor object, the current block generation node needs to interact with a third-party node to obtain behavior data of the poor object corresponding to the identity information of the poor object, at this time, identity information of the poor object obtained after processing the uplink storage request in S501 may be directly sent to the third-party node, and the third-party node searches for the behavior data of the poor object corresponding to the identity information of the poor object from the block chain or the local database according to the received identity information of the poor object, and feeds the data back to the current block generation node.

Optionally, when the identity information of the poor object is sent to the third node, the current block generation node may also generate an on-chain data query request including the identity information of the poor object first, and send the on-chain data query request to the third node. After receiving the on-chain data query request, the third-party node processes the on-chain data query request to acquire poor object identity information, then queries poor object behavior data corresponding to the poor object identity information from local data or data stored in the block chain as a query result, generates an on-chain transaction processing request comprising the queried poor object behavior data, and feeds the request back to the current block generating node, so that the current block generating node receives and responds to the on-chain transaction processing request

And S503, receiving an on-chain transaction processing request which is sent by the third-party node and comprises poor object behavior data.

S504, responding to the transaction processing request on the chain, screening the poor object according to the poor object behavior data, and writing the screening result of the poor object into the block as the transaction data.

And S505, responding to the poverty alleviation issue request comprising the target poverty alleviation condition, and determining parameters of the poverty alleviation intelligent contract according to the target poverty alleviation condition and the poverty alleviation object information in the block chain.

The poverty-alleviation rule can be a specific poverty-alleviation rule set for the poverty-alleviation item according to the related content of the poverty-alleviation item. The target poverty alleviation condition may be a judgment standard which is specified in the poverty alleviation item and can be used as the support of the poverty alleviation item, for example, which poverty alleviation types can be specific poverty alleviation objects supported by the poverty alleviation item, and may also include a dividing condition of poverty alleviation credit, for example, whether the poverty alleviation money is distributed once or multiple times; the poverty relief is divided equally for each poverty, or different poverty relief money is issued to different poverty relief objects according to poverty relief grades, and the like. The poor object information may include all information related to the poor object, such as identity information, quantity, poor object behavior data, and the like. The parameters of the intelligent contract can be related parameters in the poverty-stricken object for generating the intelligent contract, which can comprise user poverty-stricken object information and can also comprise target poverty limit, target poverty type and the like.

Specifically, when the current block generation node responds to the poverty alleviation issue request including the target poverty alleviation condition and determines the parameters of the poverty alleviation intelligent contract according to the target poverty alleviation condition and the poverty alleviation object information in the block chain, the method may include the following steps: matching the poverty type of each poverty object in the block chain with the target poverty alleviation type in the target poverty alleviation condition to determine a target poverty alleviation object; and taking the identity information and the quantity of the target poverty-relief object and the target poverty-relief amount in the target poverty-relief condition as parameters of the poverty-relief intelligent contract.

Specifically, the poverty type of each poverty object is determined, and then the matching operation between the poverty type and the target poverty alleviation type in the target poverty alleviation condition is performed, so as to determine the target poverty object, where the method for determining the poverty type of each poverty object in this embodiment may be the same as the method for determining the poverty type of each poverty object by the service application server, and is not described in detail here. After the poverty type of each poverty object is determined, the determined poverty type of each poverty object is sequentially matched with the special poverty type in the target poverty alleviation condition, and if the poverty type of each poverty object is consistent with the special poverty type in the target poverty alleviation condition, the poverty object is determined to be the target poverty object. And finally, the determined identity information of each target poverty-stricken object, the total number of the target poverty-stricken objects and the target poverty-stricken amount in the target poverty-stricken condition are used as parameters of the poverty-stricken intelligent contract.

And S506, executing the poverty-alleviation intelligent contract according to the parameters of the poverty-alleviation intelligent contract to obtain a target poverty-alleviation object and a poverty-alleviation limit of the target poverty-alleviation object, and writing the poverty-alleviation limit into a block as transaction data.

In order to ensure the disclosure transparency and traceability of the target poverty-poor object and the poverty-poor quota thereof, after the current block generation node obtains the poverty-poor quota of the target poverty-poor object and the target poverty-poor object based on the poverty-poor intelligent contract, the obtained target poverty-poor object and the poverty-poor quota of the target poverty-poor object can be written into the block as transaction data.

According to the accurate poverty alleviation method based on the block chain, provided by the embodiment of the invention, by receiving the uplink storage request comprising the identity information of the poverty alleviation object, the identity information of the poverty alleviation object is written into the block, the identity information of the poverty alleviation object is sent to the third-party node, the third-party node is requested to inquire and feed back the poverty alleviation object behavior data corresponding to the poverty alleviation identity information, after the poverty alleviation object behavior data fed back by the third-party node is received, the poverty alleviation object is screened, and the screening result is written into the block.
