Referring to fig. 1, fig. 1 is a schematic block chain network-based information processing system 10, which includes a block chain network 100 (illustratively shown to include a node 110-1 to a node 110-3), a block chain management platform 120, a pet registration system 130 (illustratively shown to belong to a terminal 131-1 of the pet registration system 130 and a graphical interface 132-1 thereof), and a pet mall system 140 (illustratively shown to belong to a terminal 141-1 of the pet mall system 140 and a graphical interface 142-1 thereof), which are described below.

The type of blockchain network 100 is flexible and may be, for example, any of a public chain, a private chain, or a federation chain. Taking a public link as an example, electronic devices such as user terminals and servers of any service entity can access the blockchain network 100 without authorization; taking a federation chain as an example, an electronic device (e.g., a terminal/server) under the jurisdiction of a service entity after obtaining authorization may access the blockchain network 100, and at this time, become a special type of node in the blockchain network 100, i.e., a client node.

Note that a client node may only provide functionality that supports the initiation of transactions by a business entity (e.g., for uplink storage of data or for querying of data on a chain), and may be implemented by default or selectively (e.g., depending on the specific business needs of the business entity) for the functionality of a conventional (native) node 110 of the blockchain network 100, such as the ranking functionality, consensus services, ledger functionality, etc., described below. Therefore, the data and the service processing logic of the service subject can be migrated to the blockchain network 100 to the maximum extent, and the credibility and traceability of the data and service processing process are realized through the blockchain network 100.

Blockchain network 100 receives transactions submitted by client nodes (e.g., terminal 131-1 attributed to pet registration system 130 and terminal 141-1 attributed to pet mall system 140 shown in fig. 1) from different business entities (e.g., pet registration system 130 and pet mall system 140 shown in fig. 1), performs the transactions to update or query the ledger, and displays various intermediate or final results of the executed transactions at the user interfaces of the terminals (e.g., graphical interface 132-1 of terminal 131-1, graphical interface 142-1 of terminal 141-1). It should be understood that, in the above, the blockchain network 100 receiving the transaction and executing the transaction specifically refers to the native node 110 in the blockchain network 100, and of course, when the client node of the business entity has the function (e.g., the consensus function, the ledger function) of the native node 110 in the blockchain network 100, the corresponding client node may also be included.

An exemplary application of the blockchain network is described below by taking an example in which a plurality of service agents access the blockchain network to implement attribute information management of pets.

Referring to fig. 1, after obtaining authorization of the blockchain management platform 120, a plurality of service entities involved in the management of the attribute information, such as the pet registration system 130 and the pet mall system 140, the terminal 131-1 of the pet registration system 130 and the terminal 141-1 of the pet mall system 140 can access the blockchain network 100.

A service person of the pet mall system 140 logs in the pet mall system 140 at the terminal 141-1 and the graphical interface 142-1 thereof, inputs a query request of pet information, the query request of the pet information is sent to the blockchain management platform 120, the blockchain management platform 120 generates a transaction corresponding to an update operation/query operation according to the query request of the pet information, a smart contract which needs to be called for realizing the update operation/query operation and parameters transferred to the smart contract are specified in the transaction, the transaction also carries a digital signature signed by the pet mall system 140 (for example, a private key in a digital certificate of the pet mall system 140 is used for encrypting a summary of the transaction), and the transaction is broadcasted to the blockchain network 100.

When the node 110 in the blockchain network 100 receives the transaction, the digital signature carried by the transaction is verified, after the digital signature is verified successfully, whether the pet mall system 140 has the transaction right is determined according to the identity of the pet mall system 140 carried in the transaction, and the transaction fails due to verification judgment of any one of the digital signature and the right verification. After successful verification, node 110's own digital signature (e.g., encrypted using node 110-1's private key to obtain a digest of the transaction) is signed and broadcast on the blockchain network 100.

After the node 110 with the sorting function in the blockchain network 100 receives the transaction successfully verified, the transaction is filled into a new block and broadcasted to the node providing the consensus service in the blockchain network 100.

The node 110 providing the consensus service in the blockchain network 100 performs the consensus process on the new block to reach an agreement, the node 110 providing the ledger function appends the new block to the tail of the blockchain, and performs the transaction in the new block: for the transaction of submitting and updating the pet attribute information, updating the key value pair corresponding to the pet attribute information in the state database; and for the transaction of inquiring the pet attribute information, inquiring the key value pair corresponding to the pet attribute information from the state database, and returning an inquiry result.

Similarly, a service person at the pet registration system 130 side may log in the pet registration system 130 in the graphic interface 132-1 of the terminal 131-1, and input initial information of the pet to store the registration information of the pet. It can be understood that the type of data that the business entity can query/update in the blockchain network 100 can be realized by restricting the authority of the transaction that the business entity can initiate, for example, when the pet mall system 140 has the authority of initiating the transaction for querying pet information, a business person of the pet mall system 140 can input a query request for pet information in the graphical interface 142-1 of the terminal 141-1, and generate a transaction broadcast for querying pet information by the blockchain management platform 120 to the blockchain network 100 to obtain corresponding pet attribute information from the blockchain network 100;

when the pet registration system 130 has the right to initiate a transaction for inquiring pet information, a service person on the pet registration system 130 side may input a pet information inquiry request in the graphical interface 132-1 of the terminal 131-1, and generate a transaction broadcast for inquiring pet information by the blockchain management platform 120 to the blockchain network 100, so as to obtain corresponding pet information from the blockchain network 100.

An exemplary functional architecture of the blockchain network provided in the embodiment of the present application is described below, referring to fig. 2, fig. 2 is a schematic functional architecture diagram of the blockchain network 100 provided in the embodiment of the present application, which includes an application layer 201, a consensus layer 202, a network layer 203, a data layer 204, and a resource layer 205, which are described below respectively.

The resource layer 205 encapsulates computing, storage, and communication resources that implement each node 110 in the blockchain network 100, such as computing, storage, and communication resources in computers, servers/clusters, and clouds, abstracts and provides a uniform interface to the data layer 204 to shield the underlying hardware implementing the resource layer 205 from differences.

The data layer 204 encapsulates various data structures that implement the ledger, including blockchains implemented in files in a file system, state databases of the key-value type, and presence certificates (e.g., hash trees of transactions in blocks).

The network layer 203 encapsulates the functions of a Point-to-Point (P2P) network protocol, a data propagation mechanism and a data verification mechanism, an access authentication mechanism and service agent identity management.

Wherein, the P2P network protocol implements communication between nodes 110 in the blockchain network 100, the data propagation mechanism ensures the propagation of transactions in the blockchain network 100, and the data verification mechanism is used for implementing the reliability of data transmission between the nodes 110 based on cryptography methods (such as digital certificates, digital signatures, public/private key pairs); the access authentication mechanism is used for authenticating the identity of the service subject added to the block chain network 100 according to an actual service scene, and endowing the service subject with the authority of accessing the block chain network 100 when the authentication is passed; the business entity identity management is used to store the identity of the business entity that is allowed to access the blockchain network 100, as well as the permissions (e.g., the types of transactions that can be initiated).

The consensus layer 202 encapsulates the functionality of the mechanisms by which the nodes 110 in the blockchain network 100 agree on a block (i.e., consensus mechanisms), transaction management, and ledger management.

The consensus mechanism comprises consensus algorithms such as POS, POW and DPOS, and the pluggable consensus algorithm is supported.

The transaction management is used for verifying the digital signature carried in the transaction received by the node 110, verifying the identity information of the service body, and judging and confirming whether the service body has the authority to perform the transaction (reading the relevant information from the identity management of the service body) according to the identity information; for the service entities authorized to access the blockchain network 100, the service entities have digital certificates issued by the certificate authority, and the service entities sign the submitted transactions by using the private keys in the digital certificates of the service entities, so as to declare the legal identities of the service entities.

The ledger administration is used to maintain blockchains and state databases. For the block with the consensus, adding the block to the tail of the block chain; and executing the transaction in the acquired consensus block, updating the key-value pairs in the state database when the transaction comprises an updating operation, inquiring the key-value pairs in the state database when the transaction comprises an inquiring operation, and returning an inquiring result to the business body. Supporting query operations for multiple dimensions of a state database, comprising: querying the chunk based on the chunk sequence number (e.g., hash value of the transaction); inquiring the block according to the block hash value; inquiring a block according to the transaction serial number; inquiring the transaction according to the transaction serial number; inquiring account data of a business main body according to an account (serial number) of the business main body; and inquiring the block chain in the channel according to the channel name.

The application layer 201 encapsulates various services that the blockchain network can implement, including tracing, crediting, and verifying transactions.

An exemplary structure of a node of the blockchain network implementing the embodiment of the present application is described below, and it is understood that the hardware structure of any type of node in the blockchain network 100 may be implemented according to the hardware structure described below.

The functions of the respective modules will be explained below.

The information processing method based on the blockchain network provided by the embodiment of the present application will be described below with reference to an exemplary application and implementation of the node 110 provided by the embodiment of the present application.

Referring to fig. 4, fig. 4 is an alternative flowchart of an information processing method based on a blockchain network according to an embodiment of the present application, and will be described with reference to the steps shown in fig. 4.

Step S401, receiving the registration information of the object to be queried sent by the registration terminal, and storing the registration information into the block chain network.

Here, the registration information refers to attribute information of the object to be queried when initially forming, and the registration information may include an identifier of the object to be queried, a structure of the object to be queried, an appearance of the object to be queried, information of other objects associated with the object to be queried, and the like.

For example, when the object to be queried is a pet, the registration information is attribute information corresponding to the pet at birth, for example, attribute information such as pet breed, birth date, weight, body type, shape, color, and the like.

In the embodiment of the application, when the pet is born, the birth information of the pet is stored in the block chain network, and the initial registration of the pet information is completed, so that the attribute information of the pet can be updated subsequently.

Step S402, receiving the registration information of the object to be inquired sent by the registration terminal, and storing the registration information into the block chain network.

Here, the registration information also includes attribute information of the object to be queried.

Step S403, receiving an information query request sent by the first terminal.

Here, the information query request at least includes an identifier of an object to be queried. The object to be queried may be any biological object having attribute information and whose attribute information can be changed, for example, the object to be queried may be an old person, a child, a pet, or the like, or the object to be queried may be any asset object having attribute information and whose attribute information can be changed, for example, a house, a car, or the like. The embodiment of the application does not limit the type of the object to be queried.

It should be noted that, for convenience of explaining the embodiments of the present application and for ensuring the clarity of explanation of the embodiments of the present application, the following description will take the object to be queried as a pet as an example.

When the object to be queried is a pet, the first terminal may be a terminal of a pet mall, a terminal held by a pet owner, a terminal of a pet management unit, a terminal of a veterinary station, a monitoring terminal in a block chain network, or the like.

The information query request is used for requesting to query attribute information of the object to be queried, for example, when the first terminal is a terminal of a pet mall, the information query request sent by a service person of the pet mall through the terminal may be a request for querying a sales volume of the pet, a current health status of a sold pet, information of the sold pet, and the like; when the first terminal is a terminal held by a pet owner, the information query request sent by the pet owner through the terminal can be a request for querying the current position of the pet, the diet condition of the pet in the recent period of time and the like; when the first terminal is a terminal of a pet management unit, the information query request sent by a service person of the pet management unit through the terminal can be a request for querying the vaccination condition, the wounded condition and the like of the pet; when the first terminal is a terminal of a veterinary kiosk, the information query request sent by a service person of the veterinary kiosk through the terminal may be a request for querying historical diseased information of a pet, and the like; when the first terminal is a monitoring terminal in a block chain network, the information query request sent by the user corresponding to the monitoring terminal may be a request for querying attribution information of the monitored pet, and the like.

In the embodiment of the present application, the blockchain network may receive an information query request sent by any node in the blockchain network.

Step S404, responding to the information inquiry request, and acquiring the attribute information of the object to be inquired from the block chain network.

Here, the blockchain network stores attribute information of the object to be queried, the blockchain network stores all attribute information of the object to be queried from a start time to a current time, and the attribute information may be pre-stored in the blockchain network. The starting time refers to a time corresponding to the object to be queried when being initially formed, for example, for a pet, the starting time may be a birth time of the pet, and for a vehicle, the starting time may be a time for starting design or production processing of the vehicle.

In the embodiment of the present application, when the information query request is received, attribute information corresponding to the information query request is queried in the block chain network in response to the information query request.

Step S405, sending the attribute information to the first terminal, so that the first terminal performs information confirmation on the object to be queried according to the attribute information.

Here, after the attribute information of the object to be queried is queried in the blockchain network, the attribute information is sent to the first terminal, and when the first terminal receives the attribute information, a user or a service person of the first terminal may perform information confirmation on the object to be queried according to the attribute information.

For example, when a pet owner sends an information query request through a terminal to request for querying the current position of the pet, the current position information of the pet is obtained in the block chain network according to the identification of the pet, and the position information is sent to the terminal of the pet owner, so that the pet owner can determine whether the pet is lost or the lost pet is quickly found back according to the position information. For another example, when a service person in the veterinary station sends an information query request through the terminal to request for querying historical illness information of a pet needing diagnosis, the historical illness information of the pet is acquired in the block chain network according to the identification of the pet, and the historical illness information is sent to the terminal of the service person in the veterinary station, so that the service person in the veterinary station takes the historical illness information of the pet as a reference to perform accurate disease diagnosis on the pet.

According to the information processing method based on the blockchain network, which is provided by the embodiment of the application, the attribute information of the object to be queried is acquired from the blockchain network in response to the information query request sent by the first terminal, so that the attribute information of the object to be queried is stored in the blockchain network, and the attribute information of the object to be queried can be prevented from being falsified by using a decentralized storage mode of the blockchain network, so that the attribute information of the object to be queried can be accurately acquired, accurate information confirmation is performed, and user experience is improved.

In some embodiments, the object to be queried may be a biological object such as a pet, an old person, or a child, or the object to be queried may be an asset object such as a vehicle, and when the object to be queried is in a lost state, a person belonging to the object to be queried needs to search for the object to be queried, so that an information query request for requesting to query location information of the object to be queried is sent to a blockchain network through a first terminal of the person belonging to the object to be queried. Correspondingly, the step S404 can be implemented by the following steps:

step S4041, in response to the information query request, obtains the location information corresponding to the time closest to the current time from the block chain network.

Here, since the owner is to search for the object to be queried, it is necessary to acquire the position information of the object to be queried at the closest time, and therefore, the position information of the object at the closest time to the current time is acquired.

It should be noted that the blockchain network includes at least one monitoring node, the monitoring node may obtain image information in real time, when the image information includes the object to be queried, store a time corresponding to the image information in the blockchain network, and store a position where the monitoring node obtains the image information as the position information in the blockchain network. Therefore, the information of the object to be queried is updated in time through at least one monitoring node in the block chain network, and further when the owner searches the object to be queried, the position information corresponding to the object to be queried at the historical moment closer to the current moment can be acquired. Therefore, the object to be queried is searched in the position corresponding to the position information or the area near the position corresponding to the position information, and the object to be queried can be quickly found.

For example, the object to be queried may be a pet, when the pet is lost, the pet owner may send an information query request in the blockchain network through the first terminal of the pet owner, at this time, the blockchain network sends pet information corresponding to the pet ID at the latest moment to the pet owner, and the pet information includes position information where the pet appears, so as to help the pet owner to find the lost pet as soon as possible.

In some embodiments, the information query request may be a query request sent after the initial registration of the object to be queried is completed, or may be a query request sent after the information update of the object to be queried is completed, so that when the information query request is received, as shown in fig. 5, the method is an optional flowchart of the information processing method based on the blockchain network provided in the embodiment of the present application, and the method includes the following steps:

step S501, receiving the registration information of the object to be queried sent by the second terminal.

Here, the registration information refers to attribute information of the object to be queried at the time of initial formation. The second terminal corresponds to the registration terminal.

Step S502, storing the registration information in the blockchain network.

Step S503, receiving an information query request sent by the first terminal, where the information query request at least includes an identifier of an object to be queried.

Here, the information query request is used to query the registration information of the object to be queried.

Step S504, responding to the information inquiry request, and acquiring the attribute information of the object to be inquired from the block chain network.

Step S505, sending the attribute information to the first terminal, so that the first terminal performs information confirmation on the object to be queried according to the attribute information.

For example, the attribute information may include the breed of the pet, and the practitioner at the veterinary kiosk wants to know the breed of the pet, so that the practitioner at the veterinary kiosk may send the information query request through the first terminal to request to query the breed of the pet, and in response, the blockchain network returns the registration information to the first terminal, so that the practitioner at the veterinary kiosk can determine the breed of the pet according to the registration information.

Referring to fig. 5, in other embodiments, after step S502, the method may further include the following steps:

step S511, receiving the registration information of the object to be queried sent by the third terminal.

Here, the third terminal corresponds to the above-described registration terminal, and the third terminal may be the same terminal as the first terminal and the second terminal or may be different terminals.

Step S512, when the registration information passes the check according to the registration information, the registration information is stored in the block chain network.

Here, the checking of the registration information according to the registration information may be to determine whether the registration information and the registration information are information for the same object to be queried, for example, the checking may be performed according to a first identifier in the registration information and a second identifier corresponding to the registration information, and if the first identifier is the same as the second identifier, the registration information and the registration information are information for the same object to be queried, and thus the checking is passed.

It should be noted that, when the block chain network stores the registration information of the object to be queried, the information query request in step S503 may be used to query the registration information of the object to be queried. Correspondingly, in step S504, in response to the information query request, attribute information of the object to be queried may be obtained from registration information of the object to be queried, which is stored in the blockchain network.

In other embodiments, when the block chain network stores the registration information and the registration information of the object to be queried at the same time, the information query request in step S503 may also be used to query the registration information and/or the registration information of the object to be queried. Correspondingly, in step S504, in response to the information query request, attribute information of the object to be queried may be obtained from registration information and/or registration information of the object to be queried, which is stored in the blockchain network.

Fig. 6 is an optional schematic flow chart of the information processing method based on the blockchain network according to the embodiment of the present application, and based on fig. 5, as shown in fig. 6, after receiving, in step S501, registration information of the object to be queried sent by the second terminal, the method further includes the following steps:

step S601, receiving authentication information uploaded by the second terminal, where the authentication information at least includes identity information of the second terminal.

Here, the authentication information uploaded by the second terminal may be signature information of a subject corresponding to the second terminal, where the subject corresponding to the second terminal may be any one of a veterinary kiosk, a pet owner, and a pet vending center. The identity authentication information is obtained by encrypting the abstract of the transaction by the second terminal by using the private key of the corresponding main body.

In some embodiments, the identity verification information may also be uploaded into the blockchain network by the second terminal at the same time as the registration information, or in other embodiments, the identity verification information may also be sent into the blockchain network by the second terminal before sending the registration information.

Step S602, verifying the identity information of the second terminal according to the public key corresponding to the second terminal.

Here, the public key corresponding to the second terminal may be obtained through the identifier of the main body corresponding to the second terminal, or the public key corresponding to the second terminal may also be obtained according to the identifier of the second terminal, where it should be noted that when the public key is obtained according to the identifier of the second terminal, the correspondence between the identifier of the second terminal and the public key corresponding to the second terminal is stored in advance.

The public key corresponding to the second terminal is acquired from the authentication center after the block chain is generated by the body such as the veterinary kiosk, the pet owner, and the pet selling center.

Correspondingly, the step S502 of storing the registration information into the blockchain network may be implemented by the following steps:

step S603, when the identity information of the second terminal passes the verification, storing the registration information in the blockchain network.

Here, the verifying the identity information of the second terminal may be that the authentication node decrypts the identity verification information of the second terminal by using the public key, compares the decryption result with the recalculated digest, and if the decryption result matches the digest, considers that the identity verification information is verified; and if the decryption result is matched with the digest ratio, the authentication information is not verified.

Referring to fig. 6 again, based on fig. 5, in another embodiment, after receiving the registration information of the object to be queried sent by the third terminal in step S511, the method may further include the following steps:

step S611, receiving authentication information uploaded by the third terminal, where the authentication information at least includes identity information of the third terminal.

Here, the authentication information uploaded by the third terminal may be signature information of a principal corresponding to the third terminal, and the principal corresponding to the third terminal may be the same as or different from the principal corresponding to the second terminal.

Step S612, verifying the identity information of the third terminal according to the public key corresponding to the third terminal.

Here, the process of verifying the identity information of the third terminal according to the public key corresponding to the third terminal may refer to the process of verifying the identity information of the second terminal according to the public key corresponding to the second terminal.

Correspondingly, when the registration information is checked according to the registration information, step S512 stores the registration information in the blockchain network, which may be implemented by the following steps:

step S613, when the identity information of the third terminal passes the verification, storing the registration information in the blockchain network.

According to the information processing method based on the blockchain network, after the registration information of the object to be inquired sent by the second terminal is received, the identity information of the second terminal is verified according to the public key corresponding to the second terminal, when the identity verification is passed, the registration information is stored in the blockchain network, after the registration information sent by the third terminal is received, the identity information of the third terminal is verified according to the public key corresponding to the third terminal, and when the identity verification is passed, the registration information is stored in the blockchain network. Therefore, the accuracy of the registration information and the registration information stored in the blockchain network can be ensured, and inaccurate information acquired in the information inquiry process in the follow-up process caused by errors of the information stored in the blockchain network is prevented.

Based on fig. 5, in some embodiments, the registration information includes an identification of the object to be queried; correspondingly, step S512 may be implemented by:

step S5121, when the identity information passes verification and the registration information sent by the third terminal passes verification according to the identifier of the object to be queried, encrypting the registration information according to the private key of the third terminal.

Here, the registration information includes change information generated when the ownership of the object to be queried is changed.

In some embodiments, step S5121 may also be implemented by: and when the identity information passes the verification and the change information passes the verification according to the identification of the object to be inquired, encrypting the change information according to the private key of each of at least two third terminals generating the change information.

Step S5122, store the encrypted registration information into at least one block in the blockchain network.

step S411, when the object to be queried is in a lost state, receiving monitoring information of the object to be queried sent by at least one monitoring terminal.

Here, when the object to be queried is lost, the owner of the object to be queried may send an update message to the blockchain network to update the state of the object to be queried, and update the state of the object to be queried to a lost state.

The monitoring terminal may be a node in the blockchain network, and the monitoring terminal may upload the shot picture or video to the blockchain network, and when it is determined that the corresponding object is related to the object to be queried according to the picture or video shot by the monitoring terminal, may upload the shot picture or video to a blockchain corresponding to the object to be queried.

Step S412, storing the monitoring information as the attribute information in the blockchain network, and sending a notification message to the first terminal.

Here, when the object to be queried is in a lost state, an information query request sent by a person to whom the object to be queried belongs through the first terminal may be received to request to query a current location of the object to be queried. When the monitoring terminal in the block chain network shoots the object to be queried, the monitoring information of the object to be queried can be stored in the block chain network for later query of the owner of the object to be queried. In some embodiments, in order to prompt the owner of the object to be queried in time, the reminding information may also be sent to the first terminal at the same time to remind the current position of the object to be queried, so that the owner can quickly find the object to be queried.

In the embodiment of the application, the reminding message may be sent to the first terminal in any form, for example, a shot picture may be sent to the first terminal, or a reminding message "monitor your pet" may be sent to the first terminal. As a prompt, the first terminal may display the prompt information in a pop-up window manner, where the prompt manner corresponding to the prompt information may include any one of a text prompt manner, a voice prompt manner, a picture prompt manner, a light prompt manner, a vibration prompt manner, and the like, or, in some embodiments, the prompt information may be displayed on the first terminal corresponding to the client of the blockchain network.

The pets need to go to relevant departments for registration regularly, the latest information is uploaded to the block chain, all nodes in the network collect the pet information within a period of time, and the pet information is integrated to form a block structure stored on the network and is diffused to the whole network. In some embodiments, after receiving data in the network, any node compares the received data with data stored by itself, removes duplicate of the compared same data, selects the latest data, and synchronizes the whole network after consensus.

Fig. 9 is a schematic diagram of an implementation process of pet vaccination information registration provided in an embodiment of the present application, where the pet vaccination information registration is performed when a pet is vaccinated, that is, the following vaccination information 901 is written into a blockchain network corresponding to a pet ID 800: time stamp, vaccine type, vaccination institution and vaccine lot, etc.

After receiving the data, the nodes in the block chain network merge the data with the same ID, and classify the pet vaccine information according to the timestamp to form a data structure as shown in fig. 10, where the pet information includes basic information 801 and vaccination information 901. After being identified together by the basic information 801 and the vaccination information 901, each node synchronizes to the whole network.

In some embodiments, when a transaction or gift occurs for a pet, the belongings of the pet are transferred, and therefore the two transferred parties need to be signed by a private key and then take effect, transaction information 1101 shown in fig. 11 is uploaded to the blockchain network: original owner, current owner and time stamp.

In some embodiments, all nodes in the blockchain network collect pet transaction transfer information over a period of time and integrate the collected information together to form a blockchain structure stored on the blockchain network and to be diffused to the entire network. After receiving the data in the block chain network, any node compares the data with the data stored by the node, forms transaction data according to the transaction timestamp sequence, compares the pet basic information data, confirms that the information of the owner is consistent with the transaction information at each step, and writes the final information of the owner into the block chain network after the network consensus.

According to the method provided by the embodiment of the application, when a pet hurts, the ID of the pet can be inquired from the block chain network according to the DNA information by acquiring the DNA information of the pet, so that the current belonged person of the pet can be found, and the person hurting accountability can be accurately realized. In addition, when the pet of the user is lost, the searching information can be uploaded at any node, after the whole network is synchronized, the searching information of the pet is synchronized to the whole network, when any monitoring node or other nodes in the network detects the pet by shooting a pet picture, the current position of the pet can be determined, and then a notice can be sent to related personnel in time to inform the current position of the pet.

According to the information processing method based on the block chain network, when pet information is inquired, each pet has the unique ID, information is recorded in the whole block chain network from birth, and the inquiry of the pet information can be carried out through characteristics such as DNA or shape, so that the problems of inquiry of the pet, wounded accountability, vaccine inspection, loss searching and the like are effectively solved, and the user experience is improved.
