     DETAILED DESCRIPTION OF EMBODIMENTS 
     Exemplary embodiments of the present disclosure will be described below with reference to accompanying drawings, which include various details of embodiments of the present disclosure to facilitate understanding and should be considered as merely exemplary. Therefore, those ordinary skilled in the art should realize that various changes and modifications may be made to embodiments described herein without departing from the scope and spirit of the present disclosure. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description. 
     The present disclosure provides a method of processing an information, which includes a request verification stage, an information storage stage, a point update stage, and an information broadcast stage. In the request verification stage, a transaction request is verified in response to the transaction request being received, and the transaction request includes the transaction information and an incentive information for the transaction information. In the information storage stage, in response to the transaction request being verified successfully, the transaction information is stored on a blockchain to obtain an updated blockchain. In the point update stage, a first existing incentive point is updated according to the incentive information to obtain an updated incentive point. In the information broadcast stage, the updated blockchain and the updated incentive point are broadcast to a plurality of blockchain nodes in a blockchain network. The incentive information includes a first quantity of incentive points, and each incentive point corresponds to a first predetermined quantity of resources. 
     An application scenario of a method and an apparatus provided by the present disclosure will be described below with reference to  FIG.  1   . 
       FIG.  1    shows a schematic diagram of an application scenario of a method and an apparatus of processing an information according to embodiments of the present disclosure. 
     As shown in  FIG.  1   , an application scenario  100  of such embodiments may include a terminal device  110 , a server  120 , and a blockchain network  130 . The terminal device  110  may be communicatively connected to the server  120  through a network, and the server  120  may be communicatively connected to a blockchain node in the blockchain network  130  through a network. The blockchain network  130  may include a plurality of blockchain nodes, and the plurality of blockchain nodes are communicatively connected to each other through a network. The network may include wired or wireless communication links. 
     The terminal device  110  may be a smart phone, a tablet computer, a laptop computer, a desktop computer, or the like. The terminal device  110  may be installed with game applications, shopping applications, audio-visual playing applications, or the like. Various types of applications may be used by a user, for example, by using the terminal device  110 , and a digital asset may be held by the user, for example, in at least one application. The digital asset may be a non-fungible token corresponding to a game prop, an electronic artwork, a sale of houses, or the like. 
     The server  120  may be, for example, a background management server that supports running of an application in the terminal device  110 . For example, a transaction request for the digital asset may be initiated by the user through the terminal device  110 , so that other users of the blockchain network may view their digital assets and perform transfer transactions of digital assets. For example, the terminal device  110  may send a transaction request to the blockchain network  130  via the background management server  120  in response to a user operation, so as to generate a block based on a transaction information of the digital asset and add the block to the blockchain, so that a decentralized registration and transfer of the digital asset may be achieved. 
     In an embodiment, a service end  140  may be provided between the background management server  120  and the blockchain network  130 . The transaction request for the digital asset initiated by the terminal device  110  may be forwarded to the service end  140  via the background management server  120 , and then forwarded to the blockchain network  130  by the service end  140 . The service end  140  may be, for example, a Software as a Service (SaaS) platform, a Backend as a Service (BaaS) platform, or the like. The service end  140  may provide, for example, an enterprise-level platform service based on a blockchain technology, so as to provide a reliable service for a digital asset transaction. 
     In an embodiments, for example, the service end  140  may maintain accounts of at least two applications in the terminal device, and provide blockchain accounts for the at least two applications. The terminal device may initiate, for example, a transaction request via the blockchain account. The service end  140  may further access an asset supervisory agency to verify a legitimacy of each digital asset requested for transaction, and only a transaction request for a legal digital asset is allowed. In this way, the service end  140  may benefit a healthy development of the digital economy. 
     The blockchain network  130  may achieve a decentralized management of the digital asset, for example, through distributed ledgers and Byzantine fault-tolerant consensus, combined with technologies such as cryptography and peer-to-peer communication. 
     It should be noted that one method of processing an information provided in the present disclosure may generally be performed by a blockchain node in the blockchain network  130 , and another method of processing an information provided in the present disclosure may generally be performed by the service end  140 . Accordingly, one apparatus of processing an information provided in the present disclosure may be  provided in a blockchain node in the blockchain network  130 , and another apparatus of processing an information provided in the present disclosure may be provided in the service end  140 . 
     It should be understood that a number and a type of terminal device, server, service end and blockchain network in  FIG.  1    are merely schematic. According to implementation needs, any number and type of terminal devices, servers, service ends and blockchain networks may be provided. 
     The methods of processing the information provided by the present disclosure will be described in detail below through  FIG.  2    to  FIG.  5    with reference to  FIG.  1   . 
       FIG.  2    shows a schematic flowchart of a service end-based method of processing an information according to embodiments of the present disclosure. 
     As shown in  FIG.  2   , a method  200  of processing an information of such embodiments includes operation S 210  to operation S 230 . The method of processing the information may be performed by a service end, and the service end may be a SaaS platform. 
     In operation S 210 , an incentive information for a transaction information is determined in response to the transaction information being received. 
     According to embodiments of the present disclosure, the transaction information may be transmitted by a user using a blockchain account via a terminal device. The transaction information may include, for example, an information of a digital asset that needs to be issued to the blockchain, or may include an information of a digital asset that needs to be transferred. The information of the digital asset may include, for example, an asset holder accounts, an asset description information, an asset category, an asset transaction type, and other information. 
     According to embodiments of the present disclosure, the incentive information may include a first quantity of incentive points. The first quantity may have a mapping relationship with the asset transaction type. Alternatively, for any type of transaction, the first quantity contained in the incentive information may be a predetermined value. The incentive point may be used to, for example, exchange resources, and each incentive point may correspond to a first predetermined quantity of resources. Through the incentive point, a blockchain node may be incentivized to participate in a maintenance of  a normal operation of the blockchain network. Each blockchain node may be associated with one or at least two applications, each application may be provided with a plurality of blockchain accounts according to requirements, and each blockchain node may be provided with a blockchain account. The incentive point may come from, for example, an account requesting a transaction (that is, a transaction request account) among the plurality of blockchain accounts, and may be transferred by the transaction request account to a blockchain account configured for a blockchain node storing the transaction information on the blockchain, so as to achieve an incentive to the blockchain account configured for the blockchain node storing the transaction information. 
     After the incentive information is determined, the incentive information may be packaged with the transaction information to form a transaction request. Then operation S 220  may be performed to send the transaction request including the transaction information and the incentive information to the blockchain network, so as to store the transaction information on the blockchain. 
     According to embodiments of the present disclosure, after determining the incentive information for the transaction information and forming the transaction request, the service end may send the transaction request to the blockchain network. After the transaction request is verified by using a smart contract, the blockchain network may add the transaction information in the transaction request to the blockchain in a form of a block. 
     For example, the blockchain node in the blockchain network may firstly encrypt the transaction information, a time information and encryption data of a latest block on the blockchain, and then add the encrypted data as a new block to an end of the blockchain, so as to complete a storage of the transaction information. 
     The blockchain node adding the transaction information to the blockchain in the form of a block may be a blockchain node associated with the application that the transaction request account belongs to, or any blockchain node in the blockchain network that is elected and determined as a consensus node. For example, each blockchain node in the blockchain network may be associated with at least one application in the terminal device, and specifically may be associated with a blockchain account provided by the at least one application. The blockchain account configured for  each blockchain node may be independent of the at least one application. After the blockchain node completes the storage of the transaction information, the blockchain node may update an existing incentive point of a corresponding blockchain account according to the incentive information in the transaction request. 
     In operation S 230 , a second existing incentive point is updated according to the incentive information. 
     After the service end sends the transaction request to the blockchain network, the existing incentive point of the transaction request account may be updated according to the determined incentive information. Specifically, the first quantity contained in the incentive information may be subtracted from the quantity of the existing incentive point, so as to update the existing incentive point. Alternatively, the service end may determine a state of the transaction information in the blockchain network through a communication with the blockchain network, and determine whether the transaction information has been stored in the blockchain according to the state. For example, after storing the transaction information on the blockchain, the blockchain network may feed back an information indicating the completion of the storage to the service end. After determining that the transaction information is stored on the blockchain, the service end may update the existing incentive point of the transaction request account according to the determined incentive information. 
     Through the method of processing the information of embodiments of the present disclosure, the incentive point corresponding to the first predetermined quantity of resources may be used to incentivize the blockchain node in the blockchain network that encrypts the transaction information to form the block. In this way, it is possible to avoid speculating on incentive points, which is conducive to the healthy development of the digital economy, and an incentive manner may not be affected by a policy restriction, so that an applicability of the method of processing the information may be improved. 
     According to the service end-based method of processing the information, the present disclosure further provides a blockchain-based method of processing an information, which will be described in detail below with reference to  FIG.  3   . 
       FIG.  3    shows a schematic flowchart of a blockchain-based method of processing an information according to embodiments of the present disclosure.  
     As shown in  FIG.  3   , a blockchain-based method  300  of processing an information of such embodiments may include operation S 310  to operation S 340 . 
     In operation S 310 , a transaction request is verified in response to the transaction request being received. 
     According to embodiments of the present disclosure, the transaction request may contain a transaction information and an incentive information for the transaction information. The transaction request may be formed by a service end packaging the incentive information and the transaction information, and the transaction request may be transmitted by the service end to a blockchain network, specifically to a blockchain node associated with the application that the transaction request account belongs to. After receiving the transaction request, the blockchain node may transmit the transaction request to a plurality of blockchain nodes communicatively connected to the blockchain node in the blockchain network, so as to perform a consensus verification. In this way, each blockchain node in the blockchain network that receives the transaction request may verify the transaction request. 
     According to embodiments of the present disclosure, a blockchain node may verify an authenticity of the transaction request by calling a smart contract. For example, the transaction information in the transaction request may include a public key of the transaction request account, a signature of the transaction request account, or the like. The blockchain node may decrypt the signature using the public key. In a case of a successful decryption, it may be determined that the transaction request is verified successfully, data or files in the transaction request are complete and accurate, and the transaction information in the transaction request comes from a blockchain account having a private key. The private key is a key paired with the public key of the transaction request account. 
     In operation S 320 , in response to the transaction request being verified successfully, the transaction information is stored on the blockchain to obtain an updated blockchain. 
     According to embodiments of the present disclosure, whether the transaction request is verified successfully may be determined according to verification results of the plurality of blockchain nodes by using a consensus mechanism such as Byzantine. For  example, if a predetermined proportion of nodes in the plurality of blockchain nodes determine that the transaction request is verified successfully, the blockchain node storing the transaction information on the blockchain may determine that the transaction request is verified successfully by the blockchain network, and then operation S 320  may be performed. It may be understood that the aforementioned predetermined proportion may be, for example, ⅔, and the predetermined proportion and the above-mentioned consensus mechanism are merely used as examples to facilitate the understanding of the present disclosure. Any consensus mechanism may be used in the present disclosure to determine whether the transaction request is verified successfully by the blockchain network. 
     According to embodiments of the present disclosure, for example, a blockchain node may firstly encrypt a transaction information, a time information, and encryption data of a latest block on the blockchain, generate a new block according to the encrypted data, and store the new block to the end of the blockchain, so as to complete a storage of the transaction information and obtain an updated blockchain. The transaction information, the time information, and the encryption data of the latest block in the blockchain may be encrypted using a hash algorithm. 
     In operation S 330 , a first existing incentive point is updated according to the incentive information, so as to obtain an updated incentive point. 
     A quantity of the existing incentive point may be added to the first quantity of incentive points contained in the incentive information to obtain an updated quantity, so as to complete the update of the first existing incentive point and obtain the updated incentive point. The first existing incentive point is a point of the blockchain account configured for the blockchain node storing the transaction information on the blockchain. 
     In operation S 340 , the updated blockchain and the updated incentive point are broadcast to the plurality of blockchain nodes in the blockchain network. 
     After the updated blockchain and the updated incentive point are broadcast to the plurality of blockchain nodes, the plurality of blockchain nodes may update a locally stored blockchain and a ledger that records a transfer of points, so that a decentralized management of the transaction information and the incentive point may be achieved. 
     Through the method of processing the information of embodiments of the present disclosure, the incentive point corresponding to the first predetermined quantity of resources may be used to incentivize the blockchain node in the blockchain network that encrypts the transaction information to form the block. In this way, it is possible to avoid speculating on incentive points, which is conducive to the healthy development of the digital economy, and an incentive manner may not be affected by a policy restriction, so that an applicability of the method of processing the information may be improved. 
     It may be understood that the transaction request may be a first request to issue a digital asset to the blockchain, or a second request to transfer a digital asset from a first blockchain account to a second blockchain account. That is, the transaction request may include a request to issue a new digital asset, or a request to grant or transfer a digital asset. The transaction information in the transaction request may be sent by the terminal device in response to a user operation. 
     In an embodiment, after receiving the transaction information, the service end may perform, for example, an integrity verification on the transaction information, so as to ensure a smooth progress of the transaction and avoid a waste of computing resources. 
     For example, the digital asset may be a virtual asset or a token corresponding to a physical asset. The digital asset may be either a fungible token or a non-fungible token (NFT). In the present disclosure, representations of various types of digital assets to be issued may be standardized, so that a transaction circulation between different types of digital assets may be performed in the blockchain network according to the transaction information sent by the terminal device. For example, the standardized representation may include a serial number of the digital asset, a number of copies of the digital asset, a description information of the digital asset, a unique random number used for a signature de-duplication, a blockchain account issuing the digital asset, a public key of the blockchain account issuing the digital asset, a signature of the blockchain account issuing the digital asset, and so on. It may be understood that the information contained in the standardized representation may be set according to actual needs, which is not limited in the present disclosure. The above-mentioned integrity verification may be performed to verify whether all standardized representations of the digital asset to be traded are contained in the transaction information. If all standardized representations are contained, it is determined that the integrity verification is successful, and the incentive information for the transaction information may be determined. Otherwise, it is determined that the integrity verification fails, then the service end may feed back a prompt information or a check page to the terminal device via the background management server, so as to prompt the transaction request account to supplement the transaction information. 
     The serial number of the digital asset and the unique random number may be assigned, for example, by the application the blockchain account belongs to. The serial number of the digital asset may include, for example, an identification of the application, so as to ensure a global uniqueness of the serial number. The signature may be obtained by encrypting, for example, by using the private key of the blockchain account, a character string and a unique random number of the transaction information obtained by using a digital digest technology. An elliptic curve encryption algorithm may be used for encryption, which is not limited in the present disclosure. The description information of the digital asset may include a title of the digital asset, a category of the digital asset, an acquisition address of the digital asset, a picture information of the digital asset and/or a text information of the digital asset, etc. The description information of the digital asset may be selected according to actual needs, which is not limited in the present disclosure. It should be noted that, when the digital asset is a non-fungible token, the standardized representation may further include, for example, the identification information of each sub-asset in the digital asset. 
     In an embodiment, the transaction request may be broadcast to the plurality of blockchain nodes by any blockchain node in the blockchain network. Therefore, any blockchain account provided in any application in the at least two applications associated with the plurality of blockchain nodes may be used as the transaction request account. The node storing the transaction information on the blockchain may be a consensus node in the plurality of blockchain nodes, and the first existing incentive point is the existing incentive point of the consensus node storing the transaction information on the blockchain. The consensus node may be elected from the plurality of blockchain nodes by using a Delegated Proof of Stake (DPoS) or any consensus mechanism. In this way, a fixed number of nodes may be elected to be responsible for the consensus of the network, which facilitates an improvement of a consensus efficiency. The node storing the transaction information may be any one of the elected consensus nodes responsible for consensus. Accordingly, the aforementioned blockchain nodes verifying the transaction information are the elected consensus nodes. Besides, all normally operating nodes in the blockchain network may participate in ledgering as supervisory nodes to receive the transaction request and provide a transaction information verification function for the blockchain accounts, so as to ensure a credibility of the network. Accordingly, the updated blockchain and the updated incentive point may be broadcast to all normally operating nodes. 
       FIG.  4    shows a schematic flowchart of exchanging points according to embodiments of the present disclosure. 
     According to embodiments of the present disclosure, the service end may send a point exchange request to the blockchain network as needed, so as to exchange incentive points with resources when a blockchain account has only a few existing incentive points. This makes it easier for the blockchain account to initiate a transaction request. Moreover, since the point may be transferred between the service side and the blockchain network, it is possible to avoid an outflow of incentive points and avoid a speculation and illegal circulation of incentive points, so that the credibility of the blockchain network may be further improved, which is conducive to improving the healthy development of the digital economy. The resources may be, for example, a legal currency or the like. 
     As shown in  FIG.  4   , in an embodiment  400 , operation S 411  may be performed by a service end  410  to send a point exchange request to the blockchain network, in response to a second existing incentive point of a blockchain account being less than a predetermined value. 
     In an embodiment, operation S 411  may be performed by the service end  410  in response to an exchange information sent by any blockchain account of any application in the at least two applications. The blockchain account may send the exchange information when the existing incentive point is less than the predetermined value. The exchange information may include a second quantity of incentive points requested for exchange. Besides, the blockchain account may further provide a certain amount of resources to an operator of the service end  410  online or offline. The service end  410  may pack the second quantity of incentive points requested for exchange and the third quantity of resources into a point exchange request. It may be understood that the quantity of the certain amount of resources may be, for example, greater than the third quantity, and a difference may be used as an operation reward for the operator of the service end. The third quantity of resources corresponds to the second quantity of incentive points. 
     After sending the point exchange request, the service end may update the existing incentive point of the aforementioned blockchain account (that is, the second existing incentive point) according to the second quantity. 
     In an embodiment, the point exchange request may be sent to any blockchain node in the blockchain network. The blockchain node may broadcast the point exchange request to other blockchain nodes. Each node in the blockchain network that receives the point exchange request may verify the point exchange request. If a predetermined proportion of nodes determine that the point exchange request is verified successfully, it may be determined that the second quantity and the third quantity in the point exchange request are accurate, and then a node having an intention of exchange in the plurality of blockchain nodes may update its existing incentive point according to the second quantity, and broadcast the updated existing incentive point to all blockchain nodes to complete the point exchange. It may be understood that when a plurality of nodes have an intention to exchange, a node that firstly broadcasts the existing incentive point may be a node that finally succeeds in the exchange. For example, a time stamp of the broadcasted existing incentive point may be used as a criterion for determination. 
     In an embodiment, for example, a first user of a blockchain account may negotiate offline with a second user of a blockchain account with a large number of incentive points, and negotiate to determine that the second user may transfer incentive points to the first user. In this case, the exchange information sent by the blockchain account may further include the blockchain account of the second user. Accordingly, the service end  410  may send the point exchange request to the blockchain node (for example, a first blockchain node  421 ) provided with the blockchain account of the second user. After the first blockchain node  421  receives the point exchange request, operation S 421  may be performed to broadcast the point exchange request to other block chain nodes  422 . Subsequently, both the first blockchain node  421  and the other block chain nodes  422  perform operation S 422  to verify the point exchange request. After the other blockchain nodes  422  determine that the point exchange request is verified successfully, operation S 423  may be performed to send a target information indicating that the point exchange request is verified successfully to the first blockchain node  421 . The first blockchain node  421  may perform operation S 424  to determine whether the target information indicating that the point exchange request is verified successfully is received from a predetermined proportion of nodes. If yes, operation S 425  is performed to update the first existing incentive point, that is, update the existing incentive point of the blockchain account of the second user. Otherwise, the first blockchain node  421  may perform operation S 426  to send an exchange failure message to the service end  410 . The service end  410  may forward the exchange failure message to the blockchain account of the first user. After the first blockchain node  421  updates the first existing incentive point, operation S 427  may be performed to send an exchange success message to the service end  410 , and the service end  410  may forward the exchange success message to the blockchain account of the first user. 
     In an embodiment, the service end  410  may perform operation S 412  to update the second existing incentive points, that is, update the existing incentive point of the blockchain account of the first user, after receiving the exchange success message. If the service end has updated the second existing incentive point after sending the point exchange request, then after receiving the exchange failure message, the service end may further change the second existing incentive point to a value before sending the point exchange request. 
     In an embodiment, the plurality of blockchain accounts provided with each application may include a management account. A transaction request initiated by any blockchain account may be sent to the blockchain network via the management account. Therefore, the aforementioned second existing incentive point may be an existing incentive point of a target account. The target account is the management account of any one of the at least two applications. The aforementioned transaction information may be sent to the service end  410  by any one of the at least two blockchain accounts contained in the application the target account belongs to, and the service end  410  may send a transaction request via the target account. Therefore, only the management account has a significance of maintaining incentive points, and the aforementioned exchange information may be sent to the service end  410  by any management account. In this way, it is possible to avoid a poor user experience caused by a case where any blockchain account needs to exchange incentive points, and thus improve a user experience. It may be understood that the management account may be, for example, a blockchain account of an application operator. 
     Exemplarily, the transaction information sent by any account may include the signature of the aforementioned blockchain account, so as to avoiding a tampering of the transaction information while improving the user experience, which is beneficial to ensure a compliance governance of the transaction and improve the credibility of the transaction. 
     Exemplarily, each blockchain node may call a smart contract for incentive points to verify the point exchange request. The smart contract for incentive points may specify, for example, a whitelist of point transfer paths. The exchange information contained in the point exchange request may further include a second transfer path, which may be represented by, for example, the blockchain account of the second user and/or the blockchain account of the first user. Such embodiments may be implemented to verify whether the transfer path belongs to a predetermined path by calling the smart contract for points. If the transfer path belongs to the predetermined path, it is determined that the point exchange request is verified successfully. 
     For example, the predetermined path may include a predetermined blockchain account, that is, the aforementioned whitelist of point transfer paths may be a whitelist of blockchain accounts, and the blockchain accounts in the whitelist of blockchain accounts include the management account of each application in the at least two applications. If the blockchain account representing the second transfer path belongs to the whitelist, it is determined that the point exchange request is verified successfully. It may be understood that the smart contract for points may be configured, for example, in a genesis block of the blockchain. Through the setting of the smart contract for incentive points, it is possible to control the circulation of incentive points, further restrict the outflow of incentive points, and avoid the speculation and illegal circulation of incentive points. It may be understood that the whitelist of blockchain accounts may further include the blockchain account configured for the consensus node. 
     In an embodiment, the service end may further communicate with a regulator, etc. to regularly acquire a list of non-compliant digital asset numbers, etc., and set a state of a digital asset corresponding to the digital asset number in the list to a transaction prohibited state. After receiving the transaction information, the service end may firstly determine a state information of the digital asset to be traded according to the digital asset number in the transaction information. If the state information is not the transaction prohibited state, it may be determined that the state information is a transaction allowed state. Then the incentive information for the transaction information may be determined. In this way, the compliance and legitimacy of the transaction may be guaranteed to a certain extent, and the healthy development of the digital economy may be further promoted. 
     In an embodiment, the incentive points may be issued by the blockchain network when the genesis block is generated, and no additional issuance will be made. That is, after the genesis block is generated, a total number of incentive points owned by all blockchain accounts is a fixed second predetermined quantity. In this way, it is possible to ensure the circulation of incentive points, and further avoid the speculation of incentive points. 
     It may be understood that, in a case of electing a consensus node using a consensus mechanism, the first blockchain node  421  and the other blockchain nodes  422  described above may both be consensus nodes. 
       FIG.  5    shows a schematic diagram of verifying a transaction request according to embodiments of the present disclosure. 
     In an embodiment, when the blockchain node in the blockchain network verifies the transaction request, the incentive information may be verified to ensure that the transfer path of the incentive point is a predetermined path. In this way, the circulation of incentive points may be controlled, the outflow of incentive points may be limited, and the speculation and illegal circulation of incentive points may be avoided. 
     For example, the incentive information may be verified by using the aforementioned smart contract for points. The incentive information may include a first point transfer path. The first point transfer path may be represented by, for example, a blockchain account sending the transaction information. 
     In an embodiment, when the transaction request is verified, the transaction information and the incentive information contained in the transaction request may be verified using different smart contracts. 
     As shown in  FIG.  5   , in an embodiment  500 , for a blockchain node that receives a transaction request  510 , a smart contract  520  for incentive points may be called to verify an incentive information  511  to determine whether the first point transfer path belongs to a predetermined path, that is, determine whether the blockchain account in the incentive information  511  belongs to a whitelist of blockchain accounts. If so, it is determined that the incentive information is verified successfully. Besides, the blockchain node may call a smart contract  530  for digital assets to verify the transaction information. If both the incentive information  511  and the transaction information  512  are verified successfully, it may be determined that the transaction request is verified successfully. 
     The transaction information may contain, for example, the signature of the transaction request account and the public key of the transaction request account, and the smart contract for digital asset in such embodiment may verify the transaction information  512  according to the signature and the public key. For example, the signature may be decrypted using the public key, and if the decryption is successful, it is determined that the transaction information  512  is verified successfully. 
     According to embodiments of the present disclosure, the blockchain network may store the transaction information in a form of a key-value pair. The service end may acquire various transaction information, for example, by providing a service interface. For example, the service end may provide the following service interfaces. 
     Digital asset issuing interface: incoming parameters may include a blockchain account issuing the digital asset, a number of copies of the digital asset, a serial number of the digital asset, a unique random number used for signature de-duplication, a public key of the blockchain account issuing the digital asset, a signature of the blockchain account issuing the digital asset, an identification of an application of the blockchain account issuing the digital asset, and so on. The incoming parameters are parameters contained in the aforementioned transaction information. It should be noted that when the issued digital asset is a non-fungible token, a serial number of a sub-asset may be passed in for each sub-asset included in the digital asset. The non-fungible token may represent a unique asset such as houses. When a user has a plurality of houses, a number different from other types of assets may be set for the asset of the house type as the number of the digital asset. Besides, a number different from other houses may be set for each of the plurality of houses, so as to obtain the number of the sub-asset. 
     Digital asset grant interface: used to grant an ownership of a digital asset to a blockchain account. The incoming parameters may include the serial number of the digital asset, the serial number of the sub-asset included in the digital asset which is a non-fungible token, the unique random number used for signature de-duplication, the identification of the blockchain account issuing the digital asset, the identification of the blockchain account that receives the digital asset, the public key of the blockchain account issuing the digital asset, the signature of the blockchain account issuing the digital asset, the identification of the application that the blockchain account issuing the digital asset belongs to, and so on. 
     Digital asset transfer interface: used to provide a function of transferring a digital asset from the first blockchain account to the second blockchain account. The incoming parameters include the serial number of the digital asset, the serial number of the sub-asset included in the digital asset which is a non-fungible token, the unique random number used for signature de-duplication, the identification of the blockchain account currently holding the digital asset, the identification of the blockchain account receiving the digital asset, the public key of the blockchain account currently holding the digital asset, the signature of the blockchain account currently holding the digital asset, the identification of the application that the blockchain account currently holding the digital asset belongs to, and so on.
