[0002] As a unique and trustworthy digital rights certificate in the blockchain network, digital asset collections can also be called non-fungible tokens (NFTs). Digital asset collections can be used for rights confirmation based on their uniqueness, and this uniqueness also leads to the uniqueness of the digital asset collections. However, with the increasing application of blockchain networks, the application of digital asset collections has also become more and more widespread, resulting in a large number of digital asset collections in the blockchain network.

[0071] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0072] Among them, if it is necessary to collect object (such as user, etc.) data in this application, a prompt interface or pop-up window will be displayed before and during the collection. The prompt interface or pop-up window is used to prompt the user that certain data is currently being collected. Only after the user confirms the prompt interface or pop-up window, the relevant steps of data acquisition are started, otherwise the process ends. Moreover, the acquired user data will be used in reasonable and legal scenarios or purposes. Optionally, in some scenarios where user data needs to be used but is not authorized by the user, authorization can be requested from the user, and the user data can be used when the authorization is passed. In other words, the use of user data in this application complies with the relevant provisions of laws and regulations, that is, the use of user data is reasonable and legal.

[0073] Among them, blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. Blockchain is essentially a decentralized database, a string of data blocks generated by cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain can include the underlying blockchain platform, platform product service layer, and application service layer.

[0074] The underlying blockchain platform can include processing modules such as user management, basic services, smart contracts, and operational detection. The user management module is responsible for the identity information management of all blockchain participants, including maintaining public and private key generation (account management), key management, and the corresponding relationship between the user's real identity and the blockchain address (authority management), etc., and, under authorization, supervises and audits the transactions of certain real identities and provides risk control rule configuration (risk control audit); the basic service module is deployed on all blockchain node devices to verify the validity of business requests, and records valid requests to storage after consensus is reached. For a new business request, the basic service first performs interface adaptation analysis and authentication processing (interface adaptation), and then encrypts the business information through the consensus algorithm (consensus management). ), and after encryption, it is completely and consistently transmitted to the shared ledger (network communication) and recorded and stored; the smart contract module is responsible for the registration and issuance of contracts, as well as contract triggering and contract execution. Developers can define the contract logic in a programming language and publish it to the blockchain (contract registration). According to the logic of the contract terms, the key or other event trigger execution is called to complete the contract logic. At the same time, it also provides the function of contract upgrade and cancellation; the operation detection module is mainly responsible for the deployment, configuration modification, contract setting, cloud adaptation and real-time status visualization output of the product during the product release process, such as alarm, network status detection and node equipment health status detection.

[0075] Smart contract: A digitally defined agreement that must run in a trusted environment, such as a blockchain platform. A computerized agreement that can execute the terms of a contract, implemented through code deployed on a shared ledger that is executed when certain conditions are met. The code is used to complete automated transactions based on actual business needs, such as querying the logistics status of the goods purchased by the buyer, and transferring the buyer's digital assets to the merchant's address after the buyer signs for the goods; of course, smart contracts are not limited to executing contracts for transactions, but can also execute contracts for processing received information.

[0076] In the examples of this application, see Figure 1 , Figure 1 This is a network interaction architecture diagram of a collection sharing provided by an embodiment of the present application, such as Figure 1As shown in the figure, the blockchain network 101 may include multiple blockchain nodes, such as blockchain node 101a, blockchain node 101b, and blockchain node 101c, etc. Users can access the blockchain network 101 through business nodes. For example, user A can access the blockchain network 101 through business node 102, and user B can access the blockchain network 101 through business node 103. Alternatively, users can directly access blockchain nodes. Among them, any user can own digital asset collections in the blockchain network 101, such as NFT collections. Through this solution, users can also share their own digital asset collections with other users to achieve the sharing of the digital asset collection by multiple users. Herein, the business node can be considered as the device used by the user. The business node can be a device deployed outside the blockchain network 101, or a blockchain node in the blockchain network 101 (i.e., users can directly access blockchain nodes), etc., which is not limited herein. The digital asset collection refers to a trusted digital rights and interests certificate with uniqueness characteristics in the blockchain network, and is a data object that can record and process multi-dimensional and complex attributes on the blockchain.

[0077] It can be understood that the blockchain nodes or business nodes mentioned in the embodiments of the present application can be a type of computer device. The computer devices in the embodiments of the present application include, but are not limited to, terminal devices or servers. In other words, the computer device can be a server or a terminal device, or a system composed of a server and a terminal device. Among them, the above-mentioned terminal device can be an electronic device, including but not limited to mobile phones, tablets, desktop computers, laptop computers, palmtop computers, in-vehicle devices, augmented reality / virtual reality (AR / VR) devices, head-mounted displays, smart TVs, wearable devices, smart speakers, digital cameras, cameras, and other mobile internet devices (MID) with network access capabilities, or terminal devices in scenarios such as trains, ships, and flights. Among them, the above-mentioned server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, vehicle-road collaboration, content delivery network (CDN), and big data and artificial intelligence platforms.

[0078] Specifically, refer to Figure 2 , Figure 2 which is a schematic diagram of a collection sharing scenario provided by the embodiments of the present application. As Figure 2As shown, the blockchain node 201 can respond to the asset sharing request for the first digital asset collection 202 of the first business node, call the collection standard interface in the digital asset standard 203, and obtain the collection receiving address of the second business node and the first token identifier 2041 of the first digital asset collection 202. The blockchain node 201 can be any blockchain node in the blockchain network, and the first business node can be a node deployed outside the blockchain network, or the blockchain node 201. The digital asset standard 203 can be considered as a technical standard for creating and managing non-forgeable digital asset collections in the blockchain network. The digital asset collection is a unique and indivisible digital asset collection. The digital asset standard 203 is a set of rules and guidelines for digital asset collections, such as the ERC-721 (Ethereum Request for Comments 721) standard. The collection standard interface can include but is not limited to sharing functions, etc. By adding the collection standard interface in the digital asset standard 203, the sharing of digital asset collections is realized. Specifically, the blockchain node 201 can call the sharing function in the collection standard interface through the collection receiving address and the first token identifier 2041, generate the second token identifier 2042 for the first digital asset collection 202, and bind the second token identifier 2042 to the resource identifier 205 of the first digital asset collection 202. This allows two identifiers to be assigned to the digital asset collection, one for unique representation, i.e., the resource identifier, and the other for collection sharing, i.e., the token identifier. Each token identifier for a digital asset collection is bound to the resource identifier of the digital asset collection, and the uniqueness of the digital asset collection is achieved. A copy of the digital asset collection is generated and shared, thereby improving the utilization rate of the digital asset collection. Furthermore, the collection sharing process for the first digital asset collection 202 can be processed on the chain.

[0079] For further information, see Figure 3 , Figure 3 1 is a flow chart of a collection sharing method based on standards provided in an embodiment of the present application. Figure 3 As shown, the collection sharing process may include the following steps:

[0080] Step S301, obtain the digital asset standard, and write the collection standard interface into the digital asset standard.

[0081] In an embodiment of the present application, a blockchain node may obtain a digital asset standard and write a collection standard interface into the digital asset standard. The collection standard interface includes a sharing event function and a sharing function. The sharing function is used to obtain the collection sharing information of the digital asset collection and share the digital asset collection to the shared node based on the collection sharing information. For example, the sharing function may be denoted as function share(B sharing parameters), where B is a positive integer, and the B sharing parameters may include, but are not limited to, a collection receiving address parameter (address to) and a shared token parameter (uint256 tokenIdToBeShared), etc. The collection receiving address parameter is used to receive the address to which the digital asset collection is shared, and the shared token parameter is used to receive the identifier of the shared token (such as the second token identifier, etc.). Optionally, the B sharing parameters may be determined based on the data requirements of the collection sharing function. The sharing event function is used to generate an event based on the data generated by the sharing function, that is, to generate a collection sharing event. The collection sharing event is equivalent to a part of the transaction result of the collection sharing transaction generated by the sharing function. For example, it may be denoted as event share(C event parameters), where C is a positive integer, and the C event parameters may include, but are not limited to, a collection sharing address parameter (address indexed from), a collection receiving address parameter (address indexed to), a sharing token parameter (uint256 indexed tokenId), and a resource identifier parameter (uint256 derivedFromtokenId), etc. The collection sharing address parameter is used to receive the address that shares the digital asset collection, the collection receiving address parameter is used to receive the address to which the digital asset collection is shared, the sharing token parameter is used to receive the identifier of the token that shares the digital asset collection (such as the first token identifier, etc.), and the resource identifier parameter is used to receive the resource identifier of the shared digital asset collection, etc.

[0082] Optionally, asset voucher information may be added to the collection standard interface; the asset voucher information includes a resource identifier parameter and a token identifier parameter; the asset voucher information is used to indicate that the resource identifier parameter is used as the unique identifier of the digital asset collection, the token identifier parameter is used as the auxiliary identifier of the digital asset collection, and the value of the token identifier parameter corresponding to the digital asset collection is one or more. For example, the asset voucher information may be denoted as (resource identifier parameter {token identifier parameter}), where one resource identifier (which may be denoted as Uniform Resource Identifier, URI) may be associated with multiple token identifiers (which may be denoted as tokenId). For example, after a digital asset collection is shared, the information related to the identifier can be seen in Table 1 below:

[0083] Table 1

[0084]

[0085] Optionally, the blockchain node may send the collection standard interface to other blockchain nodes. If each blockchain node passes the consensus on the collection standard interface, the digital asset standard including the collection standard interface is determined as the digital asset standard that can be used subsequently. Optionally, the digital asset standard can be regarded as a smart contract.

[0086] Step S302, when receiving an asset sharing request, perform sharing processing on the digital asset collection indicated by the asset sharing request based on the collection standard interface.

[0087] In the embodiment of the present application, when the blockchain node receives an asset sharing request for a digital asset collection, it may call the sharing function in the collection standard interface based on the asset sharing request to perform sharing processing on the digital asset collection. Briefly, as shown in the digital collection standard above, the user can call the sharing function in the digital collection standard to specify who (to) to share the digital asset collection with and which tokenId to share; the digital collection standard can detect whether the tokenId exists and whether it belongs to the sender, etc. If so, a new token identifier (newTokenId) is minted for the to address (i.e., the recipient) and the new token identifier is bound to the resource identifier of the digital asset collection.

[0088] Specifically, the process of sharing the collection can be referred to Figure 4 , Figure 4 is a flowchart of a method for sharing a collection provided by an embodiment of the present application. As Figure 4 shown, the process of sharing the collection includes the following steps:

[0089] Step S401, in response to an asset sharing request for a first digital asset collection of a first service node, call the collection standard interface in the digital asset standard to obtain the collection receiving address of the second service node and the first token identifier of the first digital asset collection.

[0090] In the embodiment of the present application, the first digital asset collection refers to a trusted digital equity certificate with unique characteristics in the blockchain network, and is a data object that can record and process multi-dimensional and complex attributes on the blockchain. Specifically, the blockchain node can respond to the asset sharing request for the first digital asset collection, and obtain the collection sharing information carried by the asset sharing request. The collection sharing information may include but is not limited to the collection receiving address for the first digital asset collection, and the first token identifier of the first digital asset collection. The first token identifier is the token identifier for the first digital asset collection owned by the business node that initiated the asset sharing request. Further, the collection standard interface in the digital asset standard can be called based on the collection sharing information to execute step S402. Alternatively, the asset sharing request for the first digital asset collection of the first business node can be responded to, and the collection standard interface in the digital asset standard can be called to obtain the collection sharing information carried by the asset sharing request.

[0091] Step S402, calling the sharing function in the collection standard interface through the collection receiving address and the first token identifier, generating a second token identifier for the first digital asset collection, and binding the second token identifier to the resource identifier of the first digital asset collection.

[0092] In the embodiment of the present application, the blockchain node can call the sharing function in the collection standard interface through the collection sharing information to generate a second token identifier for the first digital asset collection. Optionally, the sharing function in the collection standard interface can be called to detect the collection sharing information, and when the collection sharing information is detected, a second token identifier for the first digital asset collection is generated.

[0093] Specifically, in a method ① for detecting collection sharing information, a blockchain node can obtain a permission token identifier having collection sharing rights for a first digital asset collection through a collection management contract, and the permission token identifier is used to indicate a business node or blockchain node having collection sharing rights for the first digital asset collection. If the first token identifier belongs to a permission token identifier, and the first token identifier belongs to a sharing business node that initiates an asset sharing request, then the step of generating a second token identifier for the first digital asset collection is performed. If the first token identifier does not belong to a permission token identifier, or the first token identifier does not belong to a sharing business node that initiates an asset sharing request, then a collection sharing failure message is sent to the sharing business node. Among them, the business node indicated by the resource identifier of the first digital asset collection has a token identifier that belongs to the permission token identifier.

[0094] In a detection method for collection sharing information②, the collection owning node of the first digital asset collection can share the collection sharing authority for the first digital asset collection. Specifically, the blockchain node can obtain the authority sharing information for the first digital asset collection, call the authority sharing function in the collection standard interface based on the authority sharing information, and obtain the node identifier corresponding to the resource identifier of the first digital asset collection; the authority sharing information includes the sharing authority data for the first digital asset collection, and the collection information of the first digital asset collection. Among them, the collection information may include but is not limited to the resource identifier of the first digital asset collection, etc.; the sharing authority data may include but is not limited to the sharing authority use permission information, and the sharing authority use permission information is used to indicate the number of times the collection sharing authority of the first digital asset collection is used and / or the collection sharing authority period, etc. The node identifier to be detected of the business node to be detected that generates the authority sharing information can be obtained. If the node identifier to be detected is the same as the node identifier, a authority sharing transaction is generated based on the shared authority data, and the authority sharing transaction is processed on the chain; if the node identifier to be detected is different from the node identifier, a permission sharing failure message is sent to the business node to be detected. At this point, it can be considered that for digital asset collections, the rights management data shown in Table 2 can be associated:

[0095] Table 2

[0096]

[0097]

[0098] The relevant information of the authority may include but is not limited to the collection owner (with all the authority) and the permission information for sharing the authority, etc. For example, business node A shares the digital asset collection it owns with business node B. At this time, business node B can also be granted a certain number of collection sharing authority, such as 3 times, that is, business node B can also share the digital asset collection 3 times.

[0099] Specifically, the sharing permission data can be obtained. If the third business node in the sharing permission data includes the sharing business node that initiates the asset sharing request, the sharing permission usage license information corresponding to the sharing business node is obtained from the sharing permission data; the third business node refers to the business node that obtains the collection sharing permission for the first digital asset collection. The historical sharing use information corresponding to the sharing business node is obtained. If the historical sharing use information satisfies the sharing permission usage license information, the step of generating a second token identifier for the first digital asset collection is performed. For example, the sharing permission usage license information is the number of collection sharing permission uses "5", and the historical sharing use information is the number of times "2" has been shared. At this time, it can be considered that the historical sharing use information satisfies the sharing permission usage license information. If the third business node includes the sharing business node, and the historical sharing use information does not satisfy the sharing permission usage license information, or the third business node does not include the sharing business node, a permission sharing failure message is sent to the business node to be detected.

[0100] Of course, in this way, when the node identifier to be detected is the same as the node identifier, the token identifier of the business node indicated by the node identifier to be detected can be directly determined as the permission token identifier, such as adding a collection sharing mark to the token identifier. When the historical sharing and use information of the business node corresponding to the node identifier to be detected reaches the sharing permission use license information of the business node, the token identifier of the business node indicated by the node identifier to be detected can be deleted from the permission token identifier. At this time, the above-mentioned detection method for collection sharing information① can be directly adopted.

[0101] When generating the second token identifier, the collection management contract can be called, and the token identifier can be incremented in the collection management contract to obtain the second token identifier. Alternatively, the second token identifier can be obtained from the candidate identifier pool. This method is that when the token identifier is in use, it may be canceled. In this way, the canceled token identifier can be added to the candidate identifier pool, etc., which is not limited here. Optionally, the blockchain node can copy the first digital asset collection to obtain a copy of the first collection. Furthermore, the second token identifier can be bound to the resource identifier of the first digital asset collection.

[0102] Step S403, based on the collection receiving address, the first token identifier, the second token identifier and the resource identifier, generate a collection sharing transaction for the first digital asset collection, process the collection sharing transaction on the chain, and send the second token identifier to the second business node through the collection receiving address.

[0103] In the embodiment of the present application, the blockchain node can generate a collection sharing transaction for the first digital asset collection based on the collection receiving address, the first token identifier, the second token identifier and the resource identifier, and process the collection sharing transaction on the chain. The second token identifier and the copy of the first collection can be sent to the second business node through the collection receiving address.

[0104] Optionally, a sharing event function (i.e., event share) may be called to obtain a collection sharing transaction generated based on a sharing function, and a first collection sharing event for the first digital asset collection may be generated based on the collection sharing transaction. Further, the collection sharing transaction may be processed on-chain, or the collection sharing transaction and the first collection sharing event may be packaged and chained. Optionally, when a sharing query operation for the first digital asset collection is received, based on the resource identifier of the first digital asset collection, a historical collection sharing event associated with the first digital asset collection is obtained; the historical collection sharing event includes the first collection sharing event; and the historical collection sharing event is output.

[0105] Through the above process, a digital asset collection can be uniquely indicated by a URI (i.e., resource identifier), and different tokenIds (i.e., token identifiers) can be used to indicate the owners of different copies of the same digital asset collection, thereby achieving the sharing of digital asset collections and improving the utilization rate of digital asset collections. For details, the process can be found in Figure 5 , Figure 5 This is a schematic diagram of a collection sharing interaction process provided by an embodiment of the present application. Figure 5 As shown, the interaction process may include the following processes:

[0106] 1. The first business node requests to share the digital asset collection, that is, sends a sharing request for the digital asset collection to the blockchain node, or, if the first business node is a blockchain node, the first business node can directly respond to the collection sharing request for the digital asset collection;

[0107] 2. Blockchain nodes can call the sharing function in the collection standard interface;

[0108] 3. The blockchain node generates a second token identifier through a sharing function;

[0109] 4. The blockchain node binds the second token identifier to the URI of the digital asset collection;

[0110] 5. Blockchain nodes upload collection sharing transactions to the chain;

[0111] 6. The blockchain node may send a copy of the digital asset collection (such as the first collection copy mentioned above) and a second token identifier to the second business node.

[0112] Further optionally, the first collection graph corresponding to the first digital asset collection can be searched. If the first collection graph is found, a first sharing graph node is constructed based on the first business node and the first token identifier, a first shared graph node is constructed based on the second business node and the second token identifier, a first graph edge is constructed from the first sharing graph node to the first shared graph node, and the first sharing graph node, the first shared graph node and the first graph edge are added to the first collection graph. Figure 6 As shown in , the first token identifier is tokenId1, and the second token identifier is tokenId5. At this time, the first sharing graph node can be mapped to the node of "tokenId1 user 1", and a directed edge (i.e., the first graph edge) is derived from the node, and the first graph edge points to the first shared graph node. If the first collection graph is not found, the historical collection sharing event associated with the first digital asset collection is obtained, and the first graph node is constructed with the business node indicated in the historical collection sharing event, and the first graph edge between the first graph nodes is constructed with the first collection sharing path indicated in the historical collection sharing event, and the first graph node and the first graph edge form the first collection graph.

[0113] For example, see Figure 6 , Figure 6 This is a schematic diagram of a graph construction scenario provided in an embodiment of the present application. Figure 6 As shown, for example, for digital asset collection 1, user 1 shares digital asset collection 1 with user 2 and user 3, and user 2 shares digital asset collection 1 with user 4. Nodes are constructed with user names and tokenIds of digital asset collection 1 owned by the user, and directed edges between nodes are constructed with the sharing paths of digital asset collection 1, thereby obtaining a collection graph 601 of digital asset collection 1. Similarly, other collection graphs can be obtained, such as a collection graph 602 constructed by user 5, user 3, user 2, and user 6 for the sharing process of digital asset collection 2. Through the collection graph, the collection sharing path of the corresponding digital asset collection can be obtained. For example, user 1 and user 2 work together on a project. User 1 obtains a digital asset collection 1 to represent that user 1 has contributed to the project. However, user 1 feels that user 2 also contributed part of his achievement. Therefore, user 1 can call the sharing function of the collection standard interface through business node 1 associated with user 1 to create a copy of digital asset collection 1 for user 2. If user 2 subsequently shares the copy of digital asset collection 1 with other users, a collection sharing path can be formed, thereby forming a collection map of digital asset collection 1.

[0114] Further optionally, multiple collection graphs can be combined to obtain a social graph. Specifically, social nodes are constructed based on the user names corresponding to the nodes included in the multiple collection graphs, directed social edges between social nodes and edge information associated with the directed social edges are constructed based on the directed edges included in the multiple collection graphs and the collection sharing paths indicated by each directed edge, and the social nodes, directed social edges and edge information associated with the directed social edges form a social graph.

[0115] Specifically, in one method ①, the collection graphs corresponding to N digital asset collections can be obtained; N is a positive integer. The graph nodes indicating the same business nodes in the N collection graphs are integrated into social nodes, and the graph edges included in the N collection graphs are used to construct directed social edges between social nodes. Based on the collection sharing paths indicated by the graph edges included in the N collection graphs, the edge information of the directed social edges is determined. The social nodes, directed social edges and edge information form a social graph. Figure 6 As shown, the collection graph 601 and the collection graph 602 include users 1 to 6, and social nodes can be constructed, including social nodes corresponding to users 1 to 6. Based on the directed edges included in the collection graph 601 and the collection graph 602 and the collection sharing paths indicated by the directed edges, directed social edges are constructed. For example, the node "user 1, tokenId1" in the collection graph 601 points to the node "user 2, tokenId2", and a directed social edge (i.e., the edge from user 1 to user 2) can be constructed, as well as the edge information "URI1 (tokenId1, tokenId2)" of the directed social edge, which is used to indicate that the digital asset collection 1 indicated by URI1 is shared from tokenId1 to tokenId2. In this way, the collection graph 601 and the collection graph 602 can be integrated to obtain the social graph 603.

[0116] Among them, the multiple collection graphs may include all collection graphs constructed by the blockchain network, such as the N collection graphs in the above method ①. Alternatively, in a method ②, the digital asset collections may be divided into multiple collection clusters based on the collection type, and the collection graphs constructed by the digital asset collections included in each collection cluster may be used to form a social graph. Specifically, the blockchain node may obtain the collection types corresponding to the N digital asset collections, and divide the N digital asset collections into M collection clusters based on the N collection types; N is a positive integer, and M is a positive integer less than or equal to N; the digital asset collections included in each collection cluster have the same collection type; the collection graphs of the digital asset collections included in each collection cluster are integrated to obtain the social graphs corresponding to the M collection clusters. The integration process can refer to the description in the above method ①.

[0117] Optionally, when a new digital asset collection is generated, a new digital asset collection can be constructed and the social graph can be updated. When a new digital asset collection sharing process is generated, the collection graph and social graph corresponding to the digital asset collection can be searched, and the collection graph and social graph can be updated based on the digital asset collection sharing process. Of course, the processing of the graph can also be directly triggered by the business node.

[0118] Further optionally, the blockchain node can construct a collection social group based on the social graph. For example, a collection social group is constructed for the social graph in the above method ①. Alternatively, a collection social group can be constructed for each of the M collection clusters, and based on the collection types corresponding to the M collection clusters, conventional social data corresponding to the M collection clusters are collected, wherein conventional social data refers to data that is open and transparent and can be collected, including but not limited to transaction data and usage data for digital asset collections in each collection cluster. According to the conventional social data corresponding to each collection cluster, a collection social topic corresponding to the collection cluster is generated, and collection description information of the collection type corresponding to the M collection clusters is obtained. The collection description information is used to indicate the type and style of the corresponding collection type, for example, the collection type includes landscapes, characters, buildings, and animals, or the collection type includes cartoons, realism, and Q-version, etc. In the collection social group corresponding to each collection cluster, the collection social topic and collection description information corresponding to the collection cluster are output. Optionally, when a collection activity is generated, the collection activity is output in the collection social topic corresponding to the collection activity. The collection activity may be, but is not limited to, digital asset collection generation, collection application (such as a digital asset collection being applied to a game scene, etc.) or collection release, etc.

[0119] Further optionally, when the fourth business node generates a second digital asset collection, it obtains the first collection type of the second digital asset collection, and obtains the first collection cluster corresponding to the first collection type; in the social graph corresponding to the first collection cluster, it obtains the associated social node associated with the first collection type, and sends a collection generation message to the business node indicated by the associated social node.

[0120] Further optionally, the blockchain node may respond to the collection forward interaction operation for the third digital asset collection, obtain the second collection type of the third digital collection, and obtain the second collection cluster corresponding to the second collection type. The collection forward interaction operation may be a collection collection operation or a collection like operation, etc. The associated digital asset collection included in the second collection cluster is obtained, the second collection map of the associated digital asset collection is obtained, and the collection description address of the associated digital asset collection is determined from the second collection map; based on the collection description address, the associated digital asset collection is displayed.

[0121] In an embodiment of the present application, an asset sharing request for a first digital asset collection of a first business node can be responded to, a collection standard interface in the digital asset standard can be called, and a collection receiving address of a second business node and a first token identifier of the first digital asset collection can be obtained; the first digital asset collection refers to a trusted digital rights certificate with unique characteristics in a blockchain network; through the collection receiving address and the first token identifier, a sharing function in the collection standard interface is called to generate a second token identifier for the first digital asset collection, and the second token identifier is bound to the resource identifier of the first digital asset collection; based on the collection receiving address, the first token identifier, the second token identifier and the resource identifier, a collection sharing transaction for the first digital asset collection is generated, the collection sharing transaction is processed on the chain, and the second token identifier is sent to the second business node through the collection receiving address. In this way, a collection standard interface is added to the digital asset standard. The collection standard interface includes a sharing function, etc., through which the digital asset collection can be shared, and two identifiers are integrated for the digital asset collection, one is a resource identifier, which is used to uniquely represent the digital asset collection, and the other is a token identifier, which is used to share the collection, such as copying the digital asset collection (i.e. copying a digital asset collection, but retaining one's own version, so that the sharee has a copy of the digital asset collection), or granting a certain right to use the digital asset collection, etc. This allows the sharing of digital asset collections (i.e. copies of digital asset collections) to be achieved while retaining the uniqueness of the digital asset collection (i.e. the original digital asset collection), thereby improving the utilization rate of the digital asset collection. Moreover, the realization of the collection sharing function is integrated into the digital asset standard, which can realize the comprehensive layout of the collection sharing function in the blockchain network and improve the security of collection sharing.
