Detailed Description

To make the objects, technical solutions and advantages of one or more embodiments of the present disclosure more apparent, the technical solutions of one or more embodiments of the present disclosure will be clearly and completely described below with reference to specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of one or more embodiments of the present specification.

The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.

In the prior art, the digital collection can mean that a block chain technology is used, and a unique digital certificate is generated for a specific work and an artwork, so that the digital copyright of the work and the artwork is protected, and the real and credible digital distribution, purchase, collection and use are realized. At present, digital collections are rich in categories, including but not limited to digital pictures, music, videos, three-dimensional models, electronic tickets, digital mementos and other forms. The digital collection has the advantages of being relatively priced and convenient for people, and the like, so the digital collection is developed rapidly.

However, since the digital collection corresponds to a virtual object in the digital world, there is no real product in the real world corresponding to the virtual object. After a user purchases the digital collections, the digital collections cannot be exchanged into other products efficiently and conveniently, and the product exchange efficiency of the digital collections based on the block chain is influenced.

In order to solve the defects in the prior art, the scheme provides the following embodiments:

fig. 1 is a schematic structural diagram of a product exchange system based on digital collections in a blockchain according to an embodiment of the present disclosure. As shown in fig. 1, the product exchange system based on digital collections in blockchains may include: a first server 101 of a first organization, a second server 102 of a second organization, and a third server 104 of a third organization, etc., where the third server 104 may be a server at a blockchain network.

Specifically, the first server 101 of the first institution may obtain a product exchange request sent by the user through the user device 103, where the product exchange request may be used to request to exchange a product with a certain price with the right for the digital collection. Subsequently, the first server 101 may send a query request for the digital collection to the third server 104 of the blockchain network for processing the product exchange process of the digital collection, where the query request may be used to query whether the rights of the digital collection are transferred from the user's on-chain account to the first institution's on-chain account, and obtain the corresponding query result from the third server 104. I.e. the third server 104 may be adapted to feed back the query result to the first server 101 in response to the query request.

When the query result indicates that the authority of the digital collection has been transferred from the on-chain account of the user to the on-chain account of the first institution, the first server 101 may trigger a smart contract for product exchange, and the smart contract may be used to instruct the product with the determined price to be sent to the user, so that the user may conveniently and efficiently exchange other products from the first institution by using the digital collection.

In addition, the third organization can utilize a third server to sell the digital collections, and at least part of the resources obtained by selling the digital collections are transferred from the third organization's down-link account to the second organization's down-link account to utilize the second organization to host the resources. Based on this, the first server 101 of the first organization can also transfer the rights for the digital collection it obtained from the user to the on-chain account of the second organization, and the second server 102 of the second organization can transfer the resources corresponding to the products exchanged by the user with the digital collection from the off-chain account of the second organization to the off-chain account of the first organization to secure the rights and interests of the first organization.

The system in fig. 1 not only enables a user to exchange digital collections from a first organization conveniently and efficiently to obtain other products, but also enables a second organization to pre-store at least part of resources obtained by selling the digital collections, and enables the first organization to transfer the authority to the on-chain account of the second organization so as to obtain the resources corresponding to the products provided for the user from the off-chain account of the second organization, thereby ensuring the rights and interests of the first organization, being beneficial to maintaining the operation stability of a product exchange scheme based on the digital collections in a blockchain, and avoiding the risk that the digital collections cannot be exchanged for other products due to the closing of related organizations.

Based on the same idea, the embodiment of the present specification further provides a method corresponding to the system. Next, a method for exchanging products based on digital collections in blockchains provided in an embodiment of the specification is specifically described with reference to the accompanying drawings:

fig. 2 is a flowchart illustrating a product exchange method based on digital collections in a blockchain according to an embodiment of the present disclosure. From a procedural point of view, the executing entity of the process may be a first server at a first mechanism for providing a product with a determined price corresponding to a digital collection, or an application hosted at the first server. As shown in fig. 2, the process may include the following steps:

step 202: a first server of a first organization obtains a product exchange request sent by a user, wherein the product exchange request is used for requesting to exchange a product with a determined price by adopting the authority aiming at the digital collection.

In the embodiments of the present specification, the digital collection may refer to a unique digital certificate generated for a specific work or art using a blockchain technique, and the digital collection belongs to one of Non-homogeneous tokens (NFT), and thus belongs to one of digital assets (digitalasses).

In embodiments of the present description, a user may pay a corresponding resource to a distribution facility of a digital collection to purchase the digital collection to obtain rights (e.g., ownership) to the digital collection. Subsequently, when the user needs to exchange other products by using the digital collection, the user can generate a product exchange request by operating the application client for managing the digital collection and send the product exchange request to the first server of the first institution for providing the exchangeable products.

In practical applications, the product exchange request may carry unique identification information of the digital collections and identification information of products that the user expects to exchange by using the digital collections, so that the first server can determine specific products that the user needs to exchange and digital collections that the user needs to use to exchange specific products.

Step 204: sending a query request for the digital collection to a third server of a blockchain network for processing the product exchange process of the digital collection, wherein the query request is used for querying whether the authority of the digital collection is transferred from the on-chain account of the user to the on-chain account of the first institution.

In the embodiment of the present specification, after a user purchases a digital collection, the user uses the on-chain account of the user to manage the right to the digital collection, so that when the user uses the digital collection to exchange other products at a first institution, the user needs to transfer the right (e.g., ownership) to the on-chain account of the first institution, thereby making the first institution acquire the right and rights of the digital collection. Where an on-chain account may refer to a blockchain account registered at a blockchain network. Based on this, before the first organization sends the product which needs to be exchanged to the user in response to the product exchange request of the user, the first organization needs to send a query request to the blockchain network to identify whether the first organization has acquired the related rights and interests of the digital Tibetan used by the user for exchanging the product.

In addition, the query request can be used for requesting to identify whether the digital collection used by the user for redeeming the product is valid or not so as to avoid cheating by the user. Specifically, step 204: sending a query request for the digital collection to a third server of a blockchain network for processing a product exchange process for the digital collection may include: and sending an inquiry request containing the token of the digital collection to a third server of the block chain network, wherein the inquiry request is used for inquiring whether the owner information, the latest seller information and the attribute description information of the digital collection corresponding to the token are consistent with the information in the product exchange request. Thereby identifying whether the digital collection provided by the user was legitimately sold by the issuing authority for the digital collection, whether the user has had ownership of the digital collection provided by the user, and whether the user has transferred rights to the digital collection to an on-chain account of the first authority. Therefore, the operation safety of the product exchange scheme based on the digital collections in the block chain is guaranteed.

In practical applications, the third server may be a server for building a blockchain network, for example, the third server may be a blockchain node in the blockchain network. A third institution may utilize a third server to generate, sell, and manage the digital collection such that the third server has the capability to review sales records and product redemption records of the digital collection, such that the first server of the first institution may send a query request for the digital collection to the third server.

Step 206: and acquiring a query result returned by the third server.

Step 208: and when the inquiry result shows that the authority of the digital collection is transferred to the chain account of the first institution from the chain account of the user, triggering a smart contract for product exchange, wherein the smart contract is used for indicating that the product with the determined price is sent to the user.

In this embodiment, if the query result indicates that the authority of the digital collection has been transferred from the on-chain account of the user to the on-chain account of the first institution, it may indicate that the user in step 202 is the owner of the legitimate digital collection provided by the user, and the user has handed over the ownership of the legitimate digital collection to the first institution, so that the user may be allowed to obtain the product with a certain price corresponding to the digital collection by using the digital collection. Specifically, the first server may trigger a smart contract for product redemption to allow the user to obtain the products at the determined price that the user needs to redeem with the digital collection.

In the embodiment of the present specification, the digital collection may correspond to various types of products with a certain price, for example, the products may be physical products, such as electronic devices, daily commodities, and the like, or the products may also be virtual service type products, such as movie tickets, shopping coupons, and the like, which is not limited in particular. The number of products with a determined price sent to the user can be determined from the actual situation, the number of products being usually a positive integer.

It should be understood that the order of some steps in the method described in one or more embodiments of the present disclosure may be interchanged according to actual needs, or some steps may be omitted or deleted.

In the method in fig. 2, after obtaining a product exchange request that a user requests to exchange a product with a certain price by using a right to a digital collection, if it is determined that the right to the digital collection has been transferred from an on-chain account of the user to an on-chain account of the first mechanism, an intelligent contract for product exchange may be triggered to send the product with the certain price to the user, so that it may be ensured that the user can quickly exchange the digital collection into other products after purchasing the digital collection, which is not only beneficial to improving the operating efficiency of a product exchange scheme based on the digital collection in a block chain, but also beneficial to improving user experience.

Based on the method of fig. 2, some specific embodiments of the method are also provided in the examples of this specification, which are described below.

In the embodiment of the present specification, after receiving the digital collection transferred by the user, the first server generally needs to accurately determine the product that needs to be sent to the user, so as to guarantee the rights and interests of the user and the enterprise.

Based on this, step 208: triggering an intelligent contract for product exchange may specifically include:

determining product information corresponding to the digital collection in an intelligent contract mode; the product information is used for determining a product with a determined price corresponding to the digital collection.

Generating a product redemption instruction including the product information.

In this embodiment, it is generally required to agree in advance product information of a product that can be exchanged by a user using the digital collection, and set an intelligent contract that can be used to retrieve the product information. So that the first server can accurately determine the product information corresponding to the digital collection by operating the intelligent contract after determining that the first mechanism obtains the authority of the digital collection from the user, and generate the product exchange instruction containing the product information. And then, the product with the determined price corresponding to the product information can be sent to the user by executing the product exchange instruction.

In practical applications, intelligent contracts for retrieving product information may be typically deployed on blockchain networks for handling product exchange processes for digital collections. Therefore, the first server may send the blockchain transaction information for calling the intelligent contract to a third server of the blockchain network to trigger the operation of the intelligent contract at the third server, and then receive the operation result of the intelligent contract fed back by the third server to determine the product information corresponding to the digital collection according to the operation result of the intelligent contract.

In practical applications, when the types of the products which are allowed to be exchanged by the user by using the digital collections are various, the user can select one or more specific products which need to be exchanged by himself, and at this time, the user can also send the product information of the one or more specific products which need to be exchanged and are selected by himself to the first server through the product exchange request.

Based on the method, after the first server determines the product information which allows the user to exchange the digital Tibetan product currently based on the intelligent contract, whether the product information which allows the user to exchange the digital Tibetan product currently contains the product information of the appointed product which is selected by the user and needs to be exchanged or not can be judged, if yes, a product exchange instruction containing the product information of the appointed product can be generated, so that the appointed product can be sent to the user subsequently, and the user experience can be improved. If not, generating a product redemption instruction including product information for the specified product may be prohibited to secure the interests of the first institution providing redeemable products to the user.

In practical applications, the product information currently allowing the user to redeem the digital Tibetan does not include the product information of the specific product to be redeemed, which is selected by the user, not only may be caused by the shortage of the specific product at the first mechanism, but also may be caused by the update and modification of the product information corresponding to the digital Tibetan, which is not specifically limited.

In the embodiment of this specification, there are various implementation manners for determining the product information corresponding to the digital collection, and the following explanation is made.

Implementation mode one

Step 202: before the first server of the first institution acquires the product exchange request sent by the user, the method may further include:

acquiring first mapping relation information; the first mapping relation information is used for reflecting the mapping relation between the content data corresponding to the digital collection and the product information.

And storing the first mapping relation information.

Correspondingly, the determining the product information corresponding to the digital collection may specifically include:

metadata for the digital collection is determined from the blockchain network.

And determining product information corresponding to the digital collection according to the first mapping relation information and the metadata of the digital collection.

In the embodiment of the present specification, since the digital collection is a unique digital voucher generated for content data in various forms such as digital pictures, music, videos, three-dimensional models, electronic tickets, digital souvenirs, and the like, after the content data corresponding to the digital collection is generated, product information that can be exchanged by the digital collection can be determined according to the content data corresponding to the digital collection. In practical applications, the server for generating the content data corresponding to the digital collection and the third server for performing sales and/or product exchange on the digital collection at the blockchain network may be the same server or different servers, which is not limited in particular.

However, the first mechanism for providing the redeemable product generally needs to make an agreement with the mechanism for selling the digital collections to predetermine product information allowing the user to redeem the digital collections, and establish and store a mapping relationship between content data corresponding to the digital collections and the product information to obtain first mapping relationship information.

In this embodiment of the present specification, the digital collection may be a unique digital certificate generated for content data, and the metadata of the digital collection may be data describing a digital commodity corresponding to the unique digital certificate, and the metadata may include information such as a name, description information, and an access link of the content data corresponding to the digital collection. In practical applications, metadata of the digital collection may be stored in a blockchain network to facilitate management of the digital collection.

Since the metadata of the digital collection usually contains information for describing content data corresponding to the digital collection, the metadata of the digital collection can be acquired from a blockchain network by operating an intelligent contract, so as to determine the content data corresponding to the digital collection according to the metadata of the digital collection, and the product information having a mapping relation with the content data corresponding to the digital collection is determined as the product information corresponding to the digital collection in combination with the first mapping relation information.

In practical applications, the first mapping relationship information may be mapping relationship information determined after content data corresponding to the digital Tibetan is generated, that is, the first mapping relationship information may be mapping relationship information determined before the digital Tibetan is sold. Or, in the operation process of the digital collection service, the product information corresponding to the digital collection may also need to be changed according to the actual requirement, so that the first mapping relationship information may also be the mapping relationship information obtained by changing the initial first mapping relationship information after the digital collection is sold, which is not particularly limited.

In addition, the first server of the first mechanism may store the first mapping relationship information locally in the device, may also store the first mapping relationship information in the cloud, or may also store the first mapping relationship information in the block chain network, so that when the first server determines the product information corresponding to the digital collection, the first mapping relationship information that needs to be used may be obtained from the storage path by running an intelligent contract or using another method, which is convenient and fast.

Implementation mode two

acquiring second mapping relation information; the second mapping relation information is used for reflecting the mapping relation between the unique identification information of the digital collection and the product information.

And storing the second mapping relation information.

Correspondingly, determining the product information corresponding to the digital collection specifically may include:

and determining product information corresponding to the digital collection according to the second mapping relation information.

In this embodiment, the unique identification information of the digital collection may be used to uniquely identify the digital collection at the chain account of the first institution to which the user transfers the right, for example, the unique identification information of the digital collection may be a unique digital certificate of the digital collection for sale, and at this time, the unique identification information of the digital collection may be generated by a device at the institution for generating the digital collection. Alternatively, the unique identification information of the digital collection may also be used to uniquely identify the content data of the digital collection, for example, the unique identification information of the digital collection may be an identification number assigned to the generator of the digital collection, and in this case, the unique identification information of the digital collection may be generated by a device at an organization for generating the content data corresponding to the digital collection, which is not limited in particular.

Specifically, after content data corresponding to the digital Tibetan is generated or the digital Tibetan is generated according to the content data, unique identification information of the digital Tibetan can be determined, a first mechanism for providing redeemable products generally needs to make an appointment with a mechanism for selling the digital Tibetan to determine product information allowing a user to redeem the digital Tibetan in advance, and a mapping relation between the unique identification information of the digital Tibetan and the product information is established, so that second mapping relation information is obtained. Of course, if the product information corresponding to the digital collection needs to be changed according to the actual requirement in the operation process of the digital collection service, the initially generated second mapping relationship information may also be changed.

Subsequently, second mapping relation information can be stored in the local device, the cloud terminal or the block chain network of the first server of the first mechanism, so that after the first server acquires the right of the digital collection transferred by the user, the second mapping relation information required to be used can be acquired from the storage path by running an intelligent contract, and the product information corresponding to the unique identification information of the digital collection is determined according to the second mapping relation information of the current latest version to be used as the product information which can be exchanged by the digital collection, thereby being convenient and fast.

In the embodiment of the specification, if a redeemable product corresponding to the digital collection needs to be sent to the user through the first mechanism, resources corresponding to the product sent to the user may also need to be transferred to the first mechanism by using the second mechanism, so as to ensure the persistent and stable operation of the product redemption scheme based on the digital collection in the blockchain.

Based on this, step 206: after the query result returned by the third server is obtained, the method may further include:

and when the inquiry result shows that the authority of the digital collection is transferred to the chain account of the first organization from the chain account of the user, transferring the authority of the digital collection to the chain account of the second organization from the chain account of the first organization.

And acquiring resources corresponding to the determined price transferred from the second organization's down-link account to the first organization's down-link account. The resource corresponding to the determined price can be the product of the initial price of the digital collection and a preset coefficient.

In the embodiment of the specification, after the digital collection is sold, the third organization needs to transfer at least part of resources obtained by selling the digital collection to the offline account of the second organization within a preset time range for management and control. After the first organization obtains the authority of the digital collection transferred by the user by using the chain account, the first organization can transfer the authority of the digital collection to the chain account of the second organization and obtain the resources corresponding to the products sent to the user by the first organization from the second server, thereby ensuring the rights and interests of the first organization.

In this embodiment, the resource special item in the under-chain account of the second organization is used for the product exchange process for the digital Tibetan, so that the problem of resource appropriation can be avoided, and a user who purchases the digital Tibetan does not need to worry about the influence caused by the selling organization of the digital Tibetan or the closing of the organization which provides exchangeable products corresponding to the digital Tibetan, so as to ensure the operation stability of the product exchange scheme based on the digital Tibetan in the blockchain.

The transferring the authority of the digital collection from the chain account of the first institution to the chain account of the second institution may specifically include:

sending a permission transfer request for the digital collection to the blockchain network; the authority transfer request comprises a private key signature of the chain account of the first organization, the token of the digital collection and the chain account information of the second organization.

In this embodiment, the private key signature of the chain account of the first institution may be a digital signature generated by using the private key of the chain account of the first institution. The token (token) of the digital collection may be a unique digital voucher for the digital collection that can be considered a token for use in transferring the rights to the digital collection. The on-chain account information for the second institution may be account information for a blockchain account of the second institution for receiving the rights to the digital collection.

Specifically, after receiving the permission transfer request for the digital collection, the blockchain network may perform signature verification on the private key signature by using the public key of the linked account of the first organization stored in the blockchain network, and if the signature verification passes, the block chain network may transfer the permission of the digital collection from the linked account of the first organization to the linked account of the second organization based on the token of the digital collection, which is safe and convenient.

In this embodiment of the specification, after acquiring the resource corresponding to the digital collection from the second mechanism, the first mechanism may further determine, according to the acquired resource, the number of products that the first mechanism needs to provide to the user, so as to guarantee the rights and interests of the user.

Based on this, step 202: before the first server of the first institution acquires the product exchange request sent by the user, the method may further include:

acquiring third mapping relation information; and the third mapping relation information is used for reflecting the price corresponding to the product information convertible into the digital collection.

And storing the third mapping relation information.

After the acquiring the resource transferred from the second organization's down-link account to the first organization's down-link account corresponding to the determined price, the method further comprises:

and determining the price corresponding to the product information according to the third mapping relation information.

And determining the quantity of the products with the determined price sent to the user according to the price corresponding to the product information and the resources corresponding to the determined price acquired from the second server.

In embodiments of the present description, it is often desirable to pre-agree on the price of a product that a user is allowed to redeem with a digital collection in order for a first institution offering redeemable products to determine the number of products that need to be delivered to the user upon receiving the user's transferred digital collection.

Specifically, in the above embodiment, when the first mapping relationship information and the second mapping relationship information are generated, the product information that allows the user to exchange the digital collections is determined, at this time, the first mechanism may also make an appointment with the mechanism that distributes the digital collections to determine the prices of the products that allow the user to exchange the digital collections, so that the third mapping relationship information that reflects the prices corresponding to the product information may be generated and stored. Therefore, the association relationship among the digital collection, the product information convertible into the digital collection and the price of the product convertible into the digital collection can be determined by combining the first mapping relationship information, the second mapping relationship information and the third mapping relationship information.

Meanwhile, the first mechanism can acquire the resource corresponding to the determined price from the second mechanism by using the authority of the digital collection, so that the quotient of the resource corresponding to the determined price acquired by the first mechanism and the price corresponding to the product information can be calculated, and the quotient value is used as the number of the products required to be sent to the user by the first mechanism. For example, assuming that the amount of the resource corresponding to the determined price acquired from the second server by the first mechanism is 10, and the amount of the resource reflected by the price corresponding to the product information is 2, the number of the products that the first mechanism needs to send to the user may be 5.

In practical application, if the product price corresponding to the digital collection needs to be changed according to actual requirements in the running process of the digital collection service, the initially generated third mapping relationship information can also be changed. And then, product exchange business aiming at the digital collection needs to be developed according to the latest third mapping relation information so as to ensure rights and interests of all parties.

Based on the same idea, the embodiment of the present specification further provides another method corresponding to the above system. Next, another method for exchanging products based on digital collections in blockchains provided by the embodiments of the specification will be described in detail with reference to the accompanying drawings:

fig. 3 is a flowchart of another method for product exchange based on digital collections in blockchains according to an embodiment of the present disclosure. From a procedural perspective, the executing subject of the process may be a third server of a third institution for processing the product exchange process of the digital collection, or an application hosted at the third server. As shown in fig. 3, the process may include the following steps:

step 302: a third server of a third organization for processing the product exchange process of the digital collections acquires resource transfer information, wherein the resource transfer information is used for indicating that resources obtained by selling the digital collections are transferred to a down-link account of the third organization; the third server is a server at a blockchain network.

In an embodiment of the present specification, the third server of the third organization may be the third server in the blockchain network mentioned in

steps

204 and 206 of fig. 2. The third mechanism can use the third server to publicly sell the digital collection, so that the user can purchase the digital collection, and then the linked account of the third mechanism can acquire the resource obtained by selling the digital collection from the user, so that the third server can acquire the resource transfer message. The down-link account may be an account that is not registered in the blockchain network, for example, a payment account registered at a bank or payment application, etc.

Step 304: and transferring at least part of the resources obtained by the sale to a chain account of a second organization, wherein the resources stored in the chain account of the second organization are used for paying the determined price of the products converted by the user by using the digital collections.

In the scheme in fig. 3, after the digital collection is sold by the third organization, at least part of resources obtained by selling the digital collection is transferred to the down-chain account of the second organization for management and control, which is beneficial to avoiding the problem that resources needed to be used when the digital collection is exchanged, so that a user who purchases the digital collection does not need to worry about the influence caused by the closing of the selling organization of the digital collection or the organization which provides the products corresponding to the digital collection, and the operation stability of the product exchange scheme based on the digital collection in the blockchain is ensured.

In this embodiment, when a third organization uses a third server to sell the digital collection, it is usually necessary to determine display information for selling the digital collection in advance, so that a user can know information about the digital collection according to the display information and then decide whether to purchase the digital collection.

Based on this, step 302: before acquiring the resource transfer message, the method may further include:

determining product information corresponding to the digital collection; the product information is used for determining product information corresponding to the digital collection; the product information corresponding to the digital collection is used for reflecting the products which can be exchanged from the first organization by the user through the digital collection.

Adding the product information to display information for selling the digital collection.

In the embodiment of the present specification, a third institution that sells digital collections generally makes an agreement with a first institution that provides exchangeable products to determine in advance product information that can be exchanged by a user using the digital collections, and subsequently, when the third institution uses a third server to sell the digital collections, the third institution may determine product information corresponding to the digital collections according to the agreement and add the product information to display information for selling the digital collections, so that before the user purchases the digital collections, the user can know the following products that can be exchanged by using the purchased digital collections according to the display information, which is beneficial to improving user experience.

In the embodiment of the present specification, since each organization may need to consume a certain amount of resources in the process of developing the digital collection service, the third server does not generally transfer all resources obtained by selling the digital collection to the second server, and based on this, after selling the digital collection, the third server needs to determine the amount of resources that need to be transferred to the second server for hosting the digital collection.

Specifically, step 304: transferring at least some of the resources from the sale to a second institution's linked account may include:

an initial price for the digital collection is determined.

And multiplying the initial price by a preset coefficient to obtain the determined price corresponding to the digital collection.

Transferring the resource corresponding to the determined price to a down-link account of a second institution.

In the embodiment of the present specification, a third organization selling digital collections generally agrees with a first organization providing redeemable products with the resource allocation manner required for product redemption of the digital collections. For example, the resource allocation manner may be that a resource obtained by selling the digital collection (that is, an initial price of the digital collection) is multiplied by a preset coefficient to obtain a resource that needs to be sent to the offline account of the second organization by the third organization for storage, and then, if the user exchanges a product at the first organization by using the digital collection, the second organization may send the resource obtained for the digital collection (that is, a resource corresponding to the determined price) to the offline account of the first organization.

To illustrate this for ease of understanding, assuming that the initial price of the digital collection is 100 dollars and the predetermined factor is 80%, the exact price for the digital collection may be 80 dollars, and subsequently, a third organization may transfer the resource corresponding to the 80 dollars to the second organization's down-link account. And after the first organization transfers the authority of the digital collections to the chain account of the second organization, the second organization also needs to transfer 80-element resources to the chain account of the first organization so as to ensure the stable operation of the product exchange scheme based on the digital collections in the blockchain.

In the embodiment of the present specification, when a user needs to exchange a product with a digital collection purchased by the user at a first mechanism, the first mechanism generally needs to perform validity detection and permission transfer condition detection on the digital collection used by the user through a blockchain network, so as to ensure the operation security of a product exchange scheme based on the digital collection in the blockchain.

Based on this, step 302: after the third server of the third institution for processing the product exchange process of the digital collection acquires the resource transfer message, the method further comprises the following steps:

acquiring a query request for the digital collection sent by a first server of a first organization, wherein the query request is used for querying whether the authority of the digital collection is transferred to an on-chain account of the first organization from an on-chain account of a user; specifically, the query request may be used to query whether all the information of the digital collection corresponding to the token, the latest seller information, and the attribute description information are consistent with information in the product exchange request sent by the user to the first institution; the query request is generated by the first server after obtaining the product redemption request sent by the user.

And feeding back a query result to the first server in response to the query request.

In this specification embodiment, the third server of the third organization may be a server at a blockchain network. The third server can have the capability of looking up the sales record and the product exchange record of the digital Tibetan, so that the third server can be used for processing the query request, and the operation safety of the product exchange scheme based on the digital Tibetan in the block chain can be guaranteed.

Based on the same idea, the embodiment of the present specification further provides another method corresponding to the above system. Next, a method for exchanging products based on digital collections in blockchain provided by an embodiment of the specification will be described in detail with reference to the accompanying drawings:

fig. 4 is a flowchart illustrating another method for product redemption based on digital collections in blockchains according to embodiments of the present disclosure. From a program perspective, the execution subject of the flow may be a second server of the second organization, or an application program hosted at the second server. As shown in fig. 4, the process may include the following steps:

step 402: a second server of a second institution obtains a product redemption message for the digital collection indicating that rights to the digital collection have been transferred from an on-chain account of a first institution to an on-chain account of the second institution.

In this embodiment of the present specification, after receiving a product exchange request sent by a user, if it is determined that the authority of a digital collection has been transferred from an on-chain account of the user to an on-chain account of the first institution, a first server of the first institution may generate and send a product exchange message to a second server of a second institution.

Step 404: transferring the priced resources for the product having a correspondence with the digital collection from the second organization's down-link account to the first organization's down-link account.

In this embodiment, at least a part of the resources obtained by the third institution for selling the digital collection may be stored in the down-chain account of the second institution, and after acquiring the right (e.g., ownership) of the digital collection from the first institution, the second institution may send the specified number of resources in its down-chain account to the down-chain account of the first institution.

Specifically, before the second server of the second institution acquires the product exchange message for the digital collection, the method may further include: and acquiring a resource transfer message, wherein the resource transfer message is used for indicating that at least part of resources obtained by selling the digital collections are transferred to the downlink account of the second organization from the downlink account of the third organization which sells the digital collections.

In practical applications, for any digital collection, the specified amount of resources transferred from the third organization to the down-link account of the second organization may be the resources corresponding to the determined price obtained by multiplying the initial price of the digital collection by a preset coefficient. Such that the second server at the second institution at step 404 can transfer the specified number of resources received by the second institution earlier for the digital collection to the first institution's down-chain account to secure the first institution's rights and interests. For example, assuming that the price per unit of a product having a correspondence with a digital collection provided to the user by the first organization is 2 and the number of products is 5, the specified number of resources transferred to the down-link account of the first organization by the second organization may be 10, i.e., the price-determining resources provided to the user by the first organization for the product having a correspondence with the digital collection may be 10.

In the scheme in fig. 4, the resource specialization at the down-chain account of the second organization is used in the product exchange process of the digital Tibetan, so that after the third organization sells the digital Tibetan, at least part of the resources obtained by selling the digital Tibetan can be sent to the down-chain account of the second organization for management and control, so as to avoid the problem that the resources required to be used when the digital Tibetan is exchanged, so that a user who purchases the digital Tibetan does not need to worry about the influence caused by the selling mechanism of the digital Tibetan or the mechanism for providing the product corresponding to the digital Tibetan, and the operation stability of the product exchange scheme based on the digital Tibetan in the blockchain is favorably ensured.

Fig. 5 is a swim lane flow diagram corresponding to the method for exchanging products based on digital collections in blockchain in fig. 2-4 provided in the embodiments of the present disclosure. As shown in fig. 5, the process may involve the user, a first server of a first organization, a second server of a second organization, a third server of a third organization, and so on executing the principal. Wherein the third server of the third organization may be a server in a blockchain network.

In the stage of selling the digital collection, the third server of the third organization can acquire the content of the digital collection and generate the digital collection. The first server of the first mechanism can interact with the third server to determine the product information and the product price corresponding to the digital collection so as to generate and store at least one of the first mapping relation information and the second mapping relation information and the third mapping relation information; the first mapping relation information can be used for reflecting the mapping relation between content data corresponding to the digital collection and product information corresponding to the digital collection; the second mapping relationship information may be used to reflect a mapping relationship between the unique identification information of the digital collection and the product information; and the third mapping relation information is used for reflecting the price corresponding to the product information.

The third server of the third organization may also add product information corresponding to the digital collection to display information for selling the digital collection. The user can purchase the digital collection according to the display information and pay the resources corresponding to the digital collection, so that the offline account of the third mechanism can acquire the resources obtained by selling the digital collection from the user, and at least part of the resources obtained by selling are transferred to the offline account of the second mechanism for storage.

In the product exchange stage, a user can send a product exchange request for requesting to exchange a product with a determined price by adopting the authority aiming at the digital collection to a first server of a first institution, so that the first server can send a query request aiming at the digital collection to a third server, and if the query result returned by the third server indicates that the authority of the digital collection is transferred to an on-chain account of the first institution by the on-chain account of the user, the first server can trigger a smart contract for product exchange to send the product with the determined price to the user, so that the user can obtain the product exchanged by using the digital collection.

The first server can also transfer the authority of the digital collection from the on-chain account of the first organization to the on-chain account of the second organization, and the second server of the second organization can transfer the resources with determined prices of the products which have corresponding relations with the digital collection and are stored in the off-chain account of the second organization to the off-chain account of the first organization, so that the authority of the first organization is guaranteed.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, the apparatus shown in fig. 9-11 is substantially similar to the method embodiment, so the description is simple, and reference may be made to the partial description of the method embodiment for relevant points.

In the 90's of the 20 th century, improvements to a technology could clearly distinguish between improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements to process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital character system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as ABEL (Advanced Boolean Expression Language), AHDL (alternate Hardware Description Language), traffic, CUPL (core universal Programming Language), HDCal, jhddl (Java Hardware Description Language), lava, lola, HDL, PALASM, rhyd (Hardware Description Language), and the like, which are currently used in the field-Hardware Language. It will also be apparent to those skilled in the art that hardware circuitry for implementing the logical method flows can be readily obtained by a mere need to program the method flows with some of the hardware description languages described above and into an integrated circuit.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in purely computer readable program code means, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be conceived to be both a software module implementing the method and a structure within a hardware component.

The systems, apparatuses, modules or units described in the above embodiments may be specifically implemented by a computer chip or an entity, or implemented by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being divided into various units by function, respectively. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.

As will be appreciated by one skilled in the art, embodiments of the present invention may be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects.
