Referring to fig. 1, fig. 1 is a schematic structural diagram of a network architecture according to the present application. As shown in fig. 1, the network structure in the present application may include a number of blockchain nodes in a blockchain network, and the specific number of the number of blockchain nodes may be determined according to an actual application scenario, and generation and uplink of a digital collection of an object may be implemented through any one or more of the number of blockchain nodes, as described below. Any of the blockchain nodes may be comprised of one or more computer devices, which may be servers or other devices.

Referring to fig. 2, fig. 2 is a schematic view of a scenario for acquiring a collection according to the present application. As shown in fig. 2, each object (including object 1 to object n, where n is a positive integer, and a specific value of n may be determined according to an actual application scenario) may initiate a collection acquisition request to a blockchain node (any one or more of blockchain networks, which may be specifically determined according to an actual application scenario) through an application program in its own object terminal, where the application program may be understood as a front client of the blockchain network, and the blockchain network is a background of the application program. Each object can initiate a collection acquisition request to a blockchain node at any time through the application. It will be appreciated that the applications for each object are identical, except that the application for a different object may be logged into the object account for a different object.

The application program may be in a terminal device of the object (i.e., the object terminal), and the terminal device may include, but is not limited to, a mobile phone, a computer, an intelligent voice interaction device, an intelligent home appliance, a vehicle-mounted terminal, and the like.

When acquiring the collection acquisition request of the object, the blockchain node can acquire associated collection information of the object, wherein the associated collection information can be information which belongs to the object and is used for generating the collection. Here, when acquiring the collection acquisition request of the object 1, the blockchain node may acquire associated collection information 1 of the object 1, where the associated collection information 1 may be information that belongs to the object 1 and is used to generate a collection of the object 1; similarly, when acquiring the collection acquisition request of the object 2, the blockchain node may acquire associated collection information 1 of the object 1, where the associated collection information 2 may be information that belongs to the object 2 and is used for generating a collection of the object 2; and so on; when acquiring the collection acquisition request of the object n, the blockchain node may acquire associated collection information n of the object n, where the associated collection information n may be information that belongs to the object n and is used to generate a collection of the object n.

The blockchain node may also obtain target stock information for combining with associated stock information of the object, where the target stock information may be preset information for generating a stock of the object (e.g., a digital stock). Therefore, the blockchain node can combine the acquired associated collection information of the object with the target collection information, and then the digital collection of the object can be generated.

Here, the blockchain node may combine the associated stock information 1 and the target stock information to generate the digital stock 1 of the object 1; the blockchain node can combine the associated collection information 2 and the target collection information to generate a digital collection 2 of the object 2; and so on; the blockchain node may combine the associated stock information n and the target stock information to generate a digital stock n for the object n.

Further, the blockchain node may directly upload the generated digital collection in real-time into an object account of the object in the blockchain network. Here, the blockchain node may uplink digital collection 1 into object account 1 of object 1, the blockchain node may uplink digital collection 2 into object account 1 of object 2, and so on, the blockchain node may uplink digital collection n into object account n of object n.

By adopting the method provided by the application, the object can send a transaction (such as the transaction corresponding to the collection acquisition request) at any time, so that the real-time generation and acquisition of the corresponding digital collection can be realized, the real-time generated digital collection can be directly cast into the object account of the object, and the efficiency and flexibility of the object for acquiring the digital collection are improved.

Referring to fig. 3, fig. 3 is a flow chart of a data processing method of a blockchain network according to the present application. The execution body in the embodiment of the application can be any blockchain node (one or a plurality of blockchain nodes) in the blockchain network. Alternatively, the blockchain node may be formed by a terminal device, a server, or a combination of the terminal device and the server, which is not limited thereto. In the following, the execution subject of the embodiments of the present application will be collectively referred to as blockchain nodes. As shown in fig. 3, the method may include:

step S101, when receiving a collection acquisition request of an object, acquiring associated collection information of the object; the related collection information refers to information belonging to an object and used for generating a collection.

Optionally, the blockchain node may obtain a collection acquisition request for the object. The collection acquisition request may be triggered by an object in a corresponding application, which may be understood to be the front end of the blockchain network, which is the background of the application. The application may be an applet, software (app), web page, or the like, without limitation. The application may be a belonging DAPP (decentralized application).

The application program may be an application program in which an object account is registered, the application program of different objects may be understood as the application program in which an object account of different objects is registered, the application program may be a terminal device of the object, and the object may refer to a user, an enterprise, an organization, or the like.

Thus, optionally, the application may have a control for acquiring the collection, where the control may be triggered by an associated user operation (e.g., a click operation, a double click operation, a long press operation, a voice operation), and the object may trigger the control in the application to initiate (i.e., send) a collection acquisition request to the blockchain node by the application.

When the blockchain node acquires the collection acquisition request of the object, the blockchain node can acquire associated collection information of the object (any object can be acquired), wherein the associated collection information can be information which belongs to the object and is used for generating a collection corresponding to the object.

Wherein, different objects can have different associated stock information, so the associated stock information can be understood as a random element (random factor) for generating the digital stock, the digital stock with the characteristics of the corresponding object can be generated through the associated stock information of the objects, and different objects can generate unique digital stock through the associated stock information of the objects.

Optionally, the generated collections may also have multiple types, and the collection acquisition requests corresponding to different collections may also be different, for example, the collection acquisition request corresponding to any collection may include the type of the collection requested to be acquired by the object. Therefore, the blockchain node may obtain the collection request type of the object according to the collection acquisition request, for example, the blockchain node may extract the collection request type of the object from the collection acquisition request, that is, the collection type of the object that the object wants to request to acquire the collection through the collection acquisition request.

Furthermore, the blockchain node may obtain associated stock information of the object for generating the stock under the stock request type, and different stock request types may correspond to different associated stock information.

For example, if the collection request type is a type of digital certificate (i.e., the collection requested to be obtained is a digital certificate), the associated collection information of the object may include a certificate number of the object and/or related information (such as a name of the object) for generating the digital certificate, where the certificate number may be obtained by obtaining the block link point from the related identification information (for identifying the identity of the object) of the object to an external certificate authority. By adopting the method, the external certificate authentication mechanism does not need to generate the digital certificates of all the objects in advance, but only needs to allocate corresponding certificate numbers to all the objects, and then, all the objects can initiate a collection acquisition request aiming at the digital certificates at any time to generate and acquire own digital certificates in real time.

For another example, if the collection request type is a game level certification type (e.g., the collection requested to be obtained is a game level certification credential), the associated collection information of the object may include a game score of the object (the game score may be a game score given to the object after the game is played by the object).

Optionally, the type of the collection to be acquired by the object is not limited, the type of the collection can be determined according to the actual application scene, and the data form of the collection can be determined according to the actual application scene, for example, the collection can be any form of data such as images (e.g. certificates), videos, audios and the like.

Step S102, acquiring target collection information for combination with associated collection information; the target collection information refers to presetting is used for generating information of the collection.

Optionally, the blockchain node may further acquire collection information (may be referred to as target collection information) for combining with the associated collection information, where the target collection information may be preset information for generating a collection.

For example, the target collection information may be template data for generating a collection under the collection request type described above, i.e., the blockchain node may acquire template data for generating a collection under the collection request type described above.

For example, if the collection request type is a type of digital certificate, the template data may be a template for generating a digital certificate of the object, such as a base map for generating a digital certificate of the object.

Step S103, the associated stock information and the target stock information are combined and processed to generate the digital stock of the object.

Optionally, the blockchain node may perform a combination process on the acquired associated collection information and the target collection information of the object, so as to generate the digital collection of the object. The combination mode of the related collection information and the target collection information can also be preset. The digital collection of the object that is generated may also be referred to as a virtual asset (e.g., a digital asset) of the object, which may be a collection of the object in the form of electronic data.

For example, if the target collection information is template data for generating a collection in the collection request type, the manner of combining the associated collection information and the target collection information may include: the blockchain node can fill the associated collection information into the corresponding template position (which can be called a filling position) in the template data, so that the digital collection of the object can be generated. The template position corresponding to the associated collection information to be filled in the template data may be preset (for example, a filling position of a certificate number, and further, a filling position of a name of an object, etc.).

Referring to fig. 4, fig. 4 is a schematic view of a scenario of information combination provided by the present application. As shown in fig. 4, the target stock information may be a base map of "honor certificate", and the associated stock information may include the name "aaaaaa" of the object, the certificate number "12345" of the object, and the time when the object obtains the certificate (x years, y months, z days, may be the time when the certificate number was obtained).

The filling position of the name of the object in the target collection information may be a position 1, the filling position of the certificate number of the object in the target collection information may be a position 2, and the filling position of the time in the target collection information may be a position 3.

Thus, the blockchain network may populate a location 1 with the name "aaaaaa" of the object, populate a location 2 with the certificate number "123456" of the object, and populate a location 3 with the time "x years, y months, z days" of the object, thereby generating a honor certificate of the object, i.e., a digital stock of the generated object.

Step S104, the digital collection is uploaded into an object account of the object in the blockchain network.

Further, the blockchain node may upload the digital collection of the generated object in real time into an object account of the object in the blockchain network.

Alternatively, the blockchain node may generate a uplink transaction for the digital collection, which the blockchain node may submit to the collection uplink contract (an intelligent contract for casting the digital collection acquired by the object to the object account of the object in real time). Thus, the blockchain node may invoke the collection upload contract to upload the generated digital collection of the object into the object account of the object based on the upload transaction.

Alternatively, the digital collection of the object may be first cached in the under-chain storage location after being generated, and the address where the digital collection is stored under the chain may be referred to as the under-chain address of the digital collection, and the up-chain transaction may include a link generated based on the under-chain address.

Thus, the process of the blockchain link point to uplink the generated digital collection of the object into the object account of the object based on the uplink transaction by invoking the collection uplink contract described above may include: the blockchain node can call the collection uplink contract to extract a link generated based on the address under the link from the uplink transaction, and further, the collection uplink contract is called to acquire the digital collection of the generated object from the address under the link according to the extracted link, and the blockchain node can call the collection uplink contract to store the acquired digital collection uplink into the object account of the object.

Referring to fig. 5, fig. 5 is a schematic view of a collection uplink scenario provided by the present application. As shown in fig. 5, after the block link point generates the digital collection of the object, the digital collection may be cached in an under-chain storage device where the digital collection has a storage address (which may be referred to as an under-chain address of the digital collection).

The blockchain node may generate a uplink transaction for the digital collection that may include a link generated based on the downlink address of the digital collection. Therefore, after submitting the uplink transaction to the collection uplink request, the blockchain node can call the collection uplink contract to extract the link from the uplink transaction, so that the collection uplink contract can acquire the digital collection of the object from the corresponding link-down address of the offline storage device through the link. Further, the acquired digital collection of the object may be uploaded into the object account of the object in the blockchain network.

Optionally, the way in which the block link links link the generated digital collection of the object into the object account of the object may include: the blockchain node may uplink the generated digital collection of the object to the account address of the object in the blockchain network (which may be understood to be the transaction address of the object in the blockchain network). The account address has binding relation with the object account of the object, so that the generated digital stock of the object is uplinked to the account address of the object in the blockchain network, and the digital stock of the object is uplinked to the object account of the object.

Optionally, after the digital collection of the object is generated, the block link point may further send the digital collection to an application program of the object, the object may check the generated digital collection in the application program, after checking, a confirmation operation for the digital collection may be performed in the application program, and further the application program may generate confirmation information of the object for the digital collection to the block link node, so that the block link node may uplink the generated digital collection to an object account of the object after receiving the confirmation information of the object image for the digital collection. By the method, the object can firstly confirm the generated digital stock, and after confirmation, the accurate digital stock can be uploaded to the object account of the object.

In another embodiment, the manner in which the blockchain link point links the generated digital collection to the object in the object account of the blockchain network may further include: the blockchain node may acquire identity information of the object (or may also be referred to as identification information of the object), and the blockchain node may generate an identification (may be referred to as a collection identification, may be referred to as a token id) of the digital collection of the object according to the identity information of the object, and further, the blockchain node may associate the generated digital collection of the object and the collection identification together to be linked into an object account of the object.

More, before receiving the collection acquisition request of the object, the blockchain node may further receive an account registration request initiated by the application of the object, where the account registration request may include identity information of the object (the identity information may be different from the identity information used to generate the collection identifier described above), and the blockchain node may verify the identity information of the object in the account registration request, and if verification is successful, may invoke an account registration contract (an intelligent contract for registering the object in the blockchain network) to register a corresponding object account for the object in the blockchain network. The blockchain in the application can be a alliance chain, and the object can be registered with a real name when registered on the alliance chain.

More, if the digital collection is successfully linked to the account of the object, prompt information of success of collection acquisition can be returned to the application program of the object, the prompt information can comprise the linked digital collection, and after the application program acquires the prompt information, the prompt information can be output so as to be displayed to the object and prompt the object to successfully acquire the digital collection. The digital collection in the object account that is linked to the object belongs to the object.

Optionally, the method provided by the embodiment of the application can be designed on ERC721 (an asset standard of a blockchain network) and ERC1155 (an asset standard of a blockchain network), and the object in the application can initiate a collection acquisition request in real time, so that a digital collection with the characteristic of the object can be cast and issued in real time for the object, a random element (such as the above-mentioned associated collection information) is introduced into the digital collection, and the random element can also be different according to different collection acquisition requests initiated by different objects.

By adopting the method provided by the application, the object casting (such as generation) and the acquisition of the digital collection only need to initiate a transaction (such as the transaction for acquiring the collection initiated by the collection acquisition request), and the transaction can be triggered in real time, so that the efficiency of acquiring the corresponding digital collection by the object is improved. Because the object can acquire the own digital stock at any time, the object has flexibility in acquiring the digital stock in time. And the blockchain node can generate the unique digital stock of each object according to the associated stock information of different objects of the initiating request in real time, so that the flexibility of generating the digital stock is improved.

When receiving a collection acquisition request of an object, the application can acquire the associated collection information of the object; associated collection information refers to information pertaining to an object and is used for generating information of the collection; target collection information for combination with the associated collection information can be obtained; the target collection information is preset information for generating collections; furthermore, the associated stock information and the target stock information can be combined and processed to generate the digital stock of the object; and, the digital collection may be uploaded into an object account of the object in the blockchain network. Therefore, when the collection acquisition request of the object is received, the related collection information of the object and the target collection information used for being combined with the related collection information can be acquired in real time, the digital collection of the object can be generated in real time through the related collection information and the target collection information, and the digital collection is directly cast and linked to the object account of the object in the blockchain network, so that the efficiency of acquiring the digital collection by the object is improved, and the flexibility of acquiring the digital collection by the object is improved (for example, the flexibility of acquiring the digital collection at any time and the flexibility of acquiring different digital collections by different objects according to the related collection information of the object are improved).

Referring to fig. 6, fig. 6 is a schematic view of a scenario of data processing according to the present application. The application program of the blockchain can be the application program of the object initiating the collection acquisition request, and the background of the application program can be any blockchain node in the blockchain network.

The background of the application program can be provided with a stacking service aiming at collection user services such as a decentralization service and a collection service. The target collection information may be an image, and the overlay service may be used to overlay and combine the associated collection information and the target collection information. The decentralized service can support the registration of the object in the blockchain network, and distributes a registered unique object identification for the object, so that the blockchain node can identify the corresponding object through the object identification. The collection service may be used to correspondingly process the generated digital collection and then to link the generated digital collection, e.g., the collection service may be used to generate a link transaction for the digital collection and submit the link transaction to a collection link contract to request the link to the digital collection.

Referring to fig. 7, fig. 7 is a schematic flow chart of picking up a collection according to the present application. In the embodiment of the application, the blockchain node can comprise a decentralization service, a superposition service and a collection service aiming at collection. As shown in fig. 7, the process may include:

1. The user may register real name information (e.g., identity information) through the application to register a corresponding user account (i.e., object account) with the blockchain network, as described below.

2. The application may give the user's real name information to the de-centering service for account registration.

3. The decentralizing service can verify real name information of the user, and after verification is successful, the DID identifier (decentralizing identifier, namely the object identifier) is distributed to the user.

4. The decentralized service may submit the DID identification assigned to the user to an identity contract (e.g., an account registration contract as described above) for uplink registration, after which the user successfully registers with the user account (i.e., the object account) of the blockchain network.

5. The decentralization service can also return the DID identification to the user through the application program so as to prompt the user that the real name registration is successful.

6. And the user obtains the collection certificate through the corresponding control in the application program to trigger the application program to generate a collection obtaining request to the decentralization service.

7. After the decentralizing service successfully verifies the identity information of the user to determine that the user can acquire the corresponding collection certificate, the decentralizing service can acquire the name of the user by querying a DB (database). 8. The decentralized service may also obtain the user's certificate number by calling an external certificate subscription mechanism, and obtain the user's certificate number by using related information (such as related identity information) of the user, and may also obtain a certificate base map (which may be understood as a template, i.e. the above-mentioned target collection information) for generating the collection certificate by calling an external certificate certification authority. The name and the certificate number of the user obtained are the obtained associated collection information of the user.

9. The de-centralization service may return information about the user's credentials (including name and credential number) to the subject's application.

10. The application of the object may invoke the overlay service to combine the certificate base, the user's name, and the certificate number to generate the user's collection certificate (i.e., digital collection).

11. After generating the user's collection certificate, the overlay service may return the url (i.e., link) of the collection certificate store to the application, which may be generated by the under-chain address of the collection certificate.

12. The application may request a stock certificate from the stock service for a upchain casting of the stock certificate based on url of the stock certificate.

13. The collection service may query the decentralization service for user information (such as identity information related to the user), and then the collection service may generate a token id (which may be understood as an identifier of the collection certificate, that is, a collection identifier) of the collection certificate on the chain through the user information.

14. The collection service may combine the generated collection identification, the digital collection, and related information of the digital collection (e.g., generation time, valid status, or related descriptive information), form metaData (meta data) for the digital collection, and form a uplink transaction for the digital collection based on the metaData.

15. The collection service may cast collection credentials directly to the user account by invoking collection contracts (e.g., collection up-link contracts as described above).

16. The collection service may return casting results (e.g., cast and successful chaining results, which may include cast collection certificates) for the collection certificates to the subject's application.

17. The application (i.e., the front end) may output the stock certificate of the user to which the stock service is presented for presentation to the corresponding user.

In the above process, the user only needs to initiate a request (such as a collection acquisition request) once, so that the collection generation and the uplink process can be realized, in the above process, except that the operation that the application program sends the collection acquisition request to the blockchain node is triggered by the user, other operations (such as related requests to the overlay service and the collection service) of the application program can be spontaneously completed by the application program, and the user can not feel the operations. Alternatively, the application program can automatically complete the whole process of generating and linking the digital collection by the blockchain node without initiating related requests for the overlay service and the collection service additionally in the process.

When receiving a collection acquisition request of an object, the application can acquire the associated collection information of the object; the associated collection information is information belonging to the object and used for generating the collection; target collection information for combination with the associated collection information can be obtained; the target collection information is preset information for generating collections; furthermore, the associated stock information and the target stock information can be combined and processed to generate the digital stock of the object; and, the digital collection may be uploaded into an object account of the object in the blockchain network. Therefore, when the collection acquisition request of the object is received, the related collection information of the object and the target collection information used for being combined with the related collection information can be acquired in real time, the digital collection of the object can be generated in real time through the related collection information and the target collection information, and the digital collection is directly cast and linked to the object account of the object in the blockchain network, so that the efficiency of acquiring the digital collection by the object is improved, and the flexibility of acquiring the digital collection by the object is improved (for example, the flexibility of acquiring the digital collection at any time and the flexibility of acquiring different digital collections by different objects according to the related collection information of the object are improved).
