Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1a is a flowchart of a method for processing a digital resource based on a blockchain according to an embodiment of the present disclosure. The embodiment of the disclosure is suitable for the situation that the scene application uses the digital resources in the resource production application. The method may be performed by a digital resource processing device based on a block chain, which may be implemented in Software and/or hardware, and may be configured in a block chain network or a block chain Service based on the block chain network, for example, a Software-as-a-Service (SaaS as a Service) Service based on the block chain. As shown in fig. 1a, the method for processing digital resources based on a block chain according to this embodiment may include:

s101, responding to an access authorization request of a scene application to a blockchain wallet, determining a wallet blockchain account of a user in the blockchain wallet;

the wallet block chain account is pre-bound with a resource block chain account of a user in a resource production application;

s103, responding to a resource access request of the scene application, authenticating a resource access certificate carried in the resource access request, and inquiring digital resources of a user in the corresponding resource production application from a block chain under the condition that the authentication is passed;

and S104, feeding back the digital resources to the scene application.

Referring to fig. 1b, the web3.0 application is based on block chain deplatation, and can be roughly divided into three parts, namely a block chain network ecology, a resource generation ecology and a scene application ecology, from the perspective of production and use of digital resources. The block chain network ecology is a block chain network which is formed by a plurality of decentralized block chain nodes together, can be a alliance chain or a public chain, and is mainly responsible for providing decentralized credible cooperation capability and authority-confirming registration capability for Web3.0 application.

The resource generation ecology consists of numerous resource generation applications belonging to different corporate entities that co-cast digital resources to accomplish validation in a blockchain network. That is, the resource production application is an application for producing, holding, and changing digital resources, for example, the digital collection selling platform in the digital collection business scenario is a resource generation application. The scene ecology provides a use scene for digital resources, and is also composed of a plurality of multi-type products belonging to different company bodies. The scene application is an application which needs to use digital resources, such as an exhibition hall and a skin in a metastic application, a prop in a game, a head portrait, a skin, a background and the like in other internet products, and can provide a use scene for the digital resources with the right on the chain.

In the embodiment of the disclosure, the account system of the resource production application is upgraded from a primary structure to a secondary structure, and the account of the user in the resource production application may include a secondary structure of an internet account and a block chain account. The internet account can be obtained by registering identity attribute information such as a mobile phone number and a mailbox, and the block chain account is distributed by the block chain client and can comprise a block chain account address, a public key, a private key, a mnemonic word and the like. And the block chain account of the user in the resource production application is the resource block chain account. Digital resources held by a user in a resource production application may be saved under a resource blockchain account in a blockchain.

In the disclosed embodiments, a blockchain wallet is also built based on the blockchain network for serving as an inter-chain relay between the resource production application and the scenario application. The resource production application can bind the resource blockchain account of the resource production application to the blockchain wallet through an identity authentication mechanism, the scene application can apply access authorization to the blockchain wallet under the condition that digital resources in the resource production application need to be used, and the digital resources in the resource production application of the user can be accessed from the blockchain to the scene application after the user authorization. The identity authentication mechanism is not specifically limited in the embodiments of the present disclosure, and for example, the resource blockchain account of the user may be bound to the wallet blockchain account of the user based on OAuth (Open authentication). A user's wallet blockchain account may bind multiple resource blockchain accounts for the user.

Specifically, under the condition that digital resources need to be used, the scene application may apply access authorization to the blockchain wallet, obtain authorization information of the blockchain wallet for the scene application, and initiate an access authorization request for the blockchain wallet to the blockchain network by using the authorization information, so that the blockchain network performs the following steps: determining a wallet blockchain account of the user according to the authorization information, and acquiring a resource blockchain account bound by the wallet blockchain account; and issuing a resource access certificate (token) for the resource block chain account, and feeding back the resource block chain account and the corresponding resource access certificate to the scene application. The resource access credentials corresponding to each resource block chain account may be different.

The scene application obtains each resource blockchain account and a corresponding resource access credential from the blockchain network, and can request digital resources from the blockchain network. Specifically, the scene application may select a resource block chain account to be accessed from each resource block chain account, determine a corresponding resource access credential, generate a resource access request including the resource block chain account to be accessed and the corresponding resource access credential, and send the resource access request to the block chain network, where the following is performed by the block chain network: checking whether the resource access voucher carried in the resource access request is issued by the user, and if the resource access voucher is issued by the user, determining that the resource access voucher passes the authentication; and according to the resource block chain account to be accessed, inquiring the digital resource in the resource block chain account to be accessed from the block chain, and feeding back the inquired digital resource to the scene application. And under the condition that the authentication of the authentication access voucher fails, rejecting the resource access request. It should be noted that the scenario application only queries and uses the digital resource from the blockchain, and the digital resource still belongs to the account of the blockchain of the resource to be accessed. The scene applications and the digital resources belong to a one-to-many relationship, a plurality of scene applications can use one digital resource, and one digital resource can be used by a plurality of scene applications. But the digital resource belongs to only one resource blockchain account. Taking the example that the user a holds the digital collection 1 in the digital collection application 1, the scene application 1 and the scene application 2 can both access the digital collection 1 from the blockchain by applying for access authorization to the blockchain wallet, that is, the digital collection 1 can be applied to the scene application 1 and the scene application 2.

The embodiment of the disclosure uniformly aggregates the resource blockchain accounts of the users scattered in the resource production application into the wallet blockchain accounts of the users. On the basis, the scene application applies for access authorization to the blockchain wallet, and the blockchain network issues a resource access certificate for the resource blockchain account based on the binding relationship between the resource blockchain account and the resource blockchain account, so that the scene application accesses the digital resource in the resource blockchain account by using the resource access certificate, data communication between the scene application and the resource production application is realized, the use threshold of the scene application on the digital resource is reduced, and the processing efficiency of the digital resource is improved.

According to the technical scheme, the blockchain wallet is used as a relay of the resource production application and the scene application, the scene application requests the blockchain wallet for access authorization of the resource production application, so that a blockchain network issues a resource access certificate for a resource blockchain account, the scene application accesses the digital resources in the blockchain of the resource production application by adopting the issued resource access certificate, data communication between the scene application and the resource production application is achieved, the use threshold of the scene application on the digital resources is reduced, and the processing efficiency of the digital resources is improved.

Fig. 2 is a flowchart of another block chain-based digital resource processing method according to an embodiment of the present disclosure. The present embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 2, the method for processing digital resources based on a block chain according to this embodiment may include:

s201, extracting wallet identity information of a user from an access authorization request of a scene application to a blockchain wallet;

the wallet block chain account is pre-bound with a resource block chain account of a user in a resource production application; the wallet identity information is obtained when a user logs in a blockchain wallet authorization page embedded in the scene application;

s202, determining a wallet blockchain account of the user in a blockchain wallet according to the wallet identity information of the user;

s203, issuing a resource access certificate for the resource block chain account, and feeding back the resource block chain account and the corresponding resource access certificate to the scene application;

s204, responding to a resource access request of the scene application, authenticating a resource access certificate carried in the resource access request, and inquiring digital resources of a user in the corresponding resource production application from a block chain under the condition that the authentication is passed;

s205, feeding back the digital resources to the scene application.

In the embodiment of the disclosure, the authorization page of the blockchain wallet is embedded in the scene application, after the user logs in and authorizes the authorization page, the scene application obtains wallet identity information of the user, generates an access authorization request carrying the wallet identity information, and sends the access authorization request to the blockchain network. The block chain network extracts the wallet identity information of the user from the access authorization request, and obtains a wallet block chain account of the user and a resource block chain account corresponding to the wallet block chain account according to the wallet identity information of the user. The block chain network also issues resource access certificates for the resource block chain accounts, and feeds the resource block chain accounts and the corresponding resource access certificates back to the scene application. Selecting a resource block chain account to be accessed from the scene application, initiating a resource access request to a block chain network according to the resource block chain account to be accessed and a corresponding resource access certificate, authenticating the resource access certificate in the resource access request by the block chain network, inquiring digital resources in the resource block chain account to be accessed from the block chain if the authentication is passed, and feeding back the digital resources to the scene application, so that the scene application can use the digital resources in the resource production application.

Taking the example that the user A holds digital collections in the digital collection application 1 and the digital collection application 2, under the condition that the scene application 1 applies for access authorization of the blockchain wallet, the blockchain network can issue a resource access certificate 1 for the digital collection application 1 and a resource access certificate 2 for the digital collection application 2, and feeds back the resource blockchain account 1 of the digital collection application 1 and the corresponding resource access certificate 1 to the scene application 1, and feeds back the resource blockchain account 2 of the digital collection application 2 and the corresponding resource access certificate 2 to the scene application 1. If the scene application 1 uses the digital collection application 1 as a resource production application to be accessed, a resource access request carrying a resource block chain account 1 and a resource access certificate 1 is sent to the block chain network, the block chain network authenticates the resource access certificate 1, if the authentication is passed, the block chain network inquires the digital resource in the resource block chain account 1 from the block chain, and feeds back the digital resource to the scene application, so that the scene application can use the digital resource, for example, the digital resource is used as a prop, a head portrait, a skin, a background and the like.

In the embodiment, the authorization of the blockchain wallet is obtained by embedding the blockchain wallet authorization page in the scene application, the scene application can access the digital resources in the resource production application, and a user does not need to learn blockchain knowledge, so that the method is simple and easy to implement, wide in application range and universal. The account systems of the scene application and the resource production application are mutually independent, and the block chain wallet is used as a relay, so that data intercommunication between the scene application and the resource production application is realized.

In an optional implementation manner, the wallet identity information of the user is a wallet identity ciphertext obtained by encrypting a wallet identity original text of the user by using an access key applied in a scene; determining a wallet blockchain account of the user in a blockchain wallet according to the wallet identity information of the user, comprising: decrypting the wallet identity ciphertext by using the admission key of the scene application to obtain a wallet identity original text of the user; and determining the wallet blockchain account of the user in the blockchain wallet by adopting the decrypted wallet identity identification text.

The admission key of the scene application can be a unique key which is distributed to the scene application in advance by the blockchain network, and the admission keys of the scene applications are different. Encrypting the wallet identity original text of the user by adopting the admission key of the scene application to obtain a wallet identity ciphertext, sending the wallet identity ciphertext to the blockchain network, enabling the blockchain network to decrypt the wallet identity ciphertext by adopting the admission key of the scene application, if decryption is successful, enabling the scene application to be legal, and continuing to execute subsequent operation to obtain a wallet blockchain account of the user; and if the decryption fails, the scene application is illegal, and the operation is finished. By adopting the admission key of the scene application for encryption, only the scene application authorized by the user can use the block chain wallet of the user, thereby improving the security of data resource processing. It should be noted that data communication between the scene application and the blockchain network can be performed by using the admission key of the scene application, so as to improve the security of data communication.

According to the technical scheme of the embodiment of the disclosure, the block chain wallet authorization page is embedded in the scene application, so that the wallet authorization operation is simplified, and the universality of data resource processing can be improved; the wallet identity original text of the user is encrypted by adopting the access key applied by the scene, so that the safety of data resource processing can be improved.

s302, selecting resource block chain accounts with access rights of the scene applications from all the resource block chain accounts bound by the wallet block chain accounts based on access right configuration information of the scene applications;

s303, issuing the resource access certificate for the resource block chain account with the access authority;

s304, responding to a resource access request of the scene application, authenticating a resource access certificate carried in the resource access request, and inquiring digital resources of a user in the corresponding resource production application from a block chain under the condition that the authentication is passed;

s305, feeding back the digital resources to the scene application.

In the embodiment of the present disclosure, the access authority configuration information of the scenario application is access authority information of the scenario application on the resource production application. In particular, the blockchain wallet may also provide a uniform resource management portal for the user, and access rights to each resource production application may be configured for the scene application through the blockchain wallet. That is, the scene application does not have access to each resource blockchain account bound by the blockchain wallet, but only has access to a part of resource blockchain accounts authorized by the user. And the block chain network issues the resource access certificate only for the resource block chain account with the access permission of the scene application.

Still taking the example that the user a has the resource block chain account 1 and the resource block chain account 2, the user may configure the scene application to have access permission only to the resource block chain account 1 and have no access permission to the resource block chain account 2, so that the scene application may only access the digital resource in the resource production application 1 through the block chain wallet and may not leak the digital resource in the resource production application 2 to the scene application. A resource management entrance is provided through the blockchain wallet, so that a user can flexibly configure access authority of a resource blockchain account for scene application, the user can flexibly manage the disclosure range of own digital resources conveniently, and the privacy of the user and the safety of the digital resources are ensured.

In an optional implementation manner, the authenticating a resource access credential carried in a resource access request in response to a resource access request of a scenario application, and querying a digital resource of a user in a corresponding resource production application from a blockchain if the authentication is passed includes: extracting a resource block chain account to be accessed and a corresponding resource access certificate from a resource access request of a scene application; authenticating the resource access certificate, determining a digital resource list in the resource block chain account under the condition that the authentication is passed, and feeding back the digital resource list to the scene application; and responding to the scene application to select the digital resource list, and inquiring the selected digital resource from the block chain.

In the embodiment of the present disclosure, when a scene application needs to access any one resource blockchain account, the blockchain network may determine a digital resource list in the resource blockchain account, and feed back the digital resource list to the scene application, and the scene application selects a digital resource to be used from the digital resource list, and further queries the digital resource to be used from the blockchain through the blockchain network. The blockchain network can further improve the flexibility of the use of the digital resources by providing a digital resource list in the resource production application for the selection of the scene application.

In an alternative embodiment, the method further comprises: and under the condition that the digital resources in the resource block chain account are changed, synchronously updating the digital resource list to the scene application.

Under the condition that the digital resources in the resource production application to be accessed are changed, for example, the resource block chain account acquires new digital resources, or the digital resources in the resource block chain account are transferred out, the block chain network can keep the accuracy of the digital resource list displayed by the scene application by synchronously updating the digital resource list to the scene application, so that the use efficiency of the scene application on the digital resources is further improved.

It should be noted that, the scenario application may also query whether the specified digital resource exists in the resource block chain account. Specifically, the scene application may obtain a target digital resource ID to be used, and send the target digital resource ID to the blockchain network, so that the blockchain network queries whether the target digital resource belongs to the resource blockchain account, and if so, queries the target digital resource from the blockchain, and provides the target digital resource to the scene application. The blockchain network may not only provide the digital resource itself to the scene application, but also provide the attribute information of the digital resource to the scene application, for example, the digital resource may be traced through the blockchain.

According to the technical scheme, a uniform resource management entrance is provided for the user through the blockchain wallet, the access authority of the scene application to the resource production application can be flexibly configured, the scene application can use the digital resources in various ways, and the use safety and flexibility of the scene application to the data resources are further improved.
