Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a system architecture of a data processing method according to an embodiment of the present invention. The system architecture diagram includes aterminal 101 of a first subscriber identity, aterminal 102 of a second subscriber identity, ablockchain network 103, afirst server 104, and asecond server 105. Wherein theterminal 101 of the first subscriber identity, theterminal 102 of the second subscriber identity and thefirst server 104 are nodes in theblockchain network 103.

Theterminal 101 of the first subscriber identity may be understood as a terminal of the buyer; theterminal 102 of the second subscriber identity may be understood as a terminal of the seller; thefirst server 104 is used for storing authorization information corresponding to the target object identification uploaded by the seller. The target object may be various digital resources, such as an application, an electronic book, a movie, and the like; the target object identifier is used for uniquely identifying a target object, for example, a unique serial Number is set for an application program in a transaction process, an ISBN (International Standard Book Number) of an electronic Book can be used as a unique identifier in a transaction process of the electronic Book, and the like; the authorization information corresponding to the target object identifier may be an activation code, an authorization code, a license, and the like; thesecond server 105 is a server of the payment platform for completing the transfer of the digital assets down the chain, e.g. a server of WeChat, a server of a bank, etc.

In one implementation manner, the authorization information corresponding to the first target object identifier is uploaded to thefirst server 104 by theterminal 102 of the second user identifier, that is, the authorization information corresponding to the first target object identifier is owned by the second user. In the implementation that theterminal 101 of the first user identifier purchases the authorization information corresponding to the first target object identifier from theterminal 102 of the second user identifier, specifically: the terminal 102 (seller) of the second user identifier may send the authorization information corresponding to the first target object identifier to thefirst server 104 through theblockchain network 103, and after receiving the authorization information corresponding to the first target object identifier, thefirst server 104 may store the authorization information corresponding to the first target object identifier. After storing the authorization information corresponding to the first target object identifier, thefirst server 104 may further push relevant information of the authorization information corresponding to the first target object identifier, for example, the first target object identifier, the profile of the authorization information corresponding to the first target object identifier, the public key of the second user, and the like, to terminals of the respective user identifiers, including theterminal 101 of the first user identifier and theterminal 102 of the second user identifier. Theterminal 101 of the first user identifier may output the related information of the authorization information corresponding to the first target object identifier based on the client, so that the first user may purchase the authorization information corresponding to the first target object identifier from the second user based on the client when viewing the related information of the authorization information corresponding to the first target object identifier.

The terminal 101 (buyer) of the first subscriber identity may add value to the wallet address of the first subscriber identity before purchasing the authorization information corresponding to the first target object identity. Wherein the wallet address of the first user identification indicates a wallet address used by the first user to conduct transactions (payments, collections) of digital assets in the blockchain network. In one implementation, theterminal 101 of the first subscriber identity sends a recharge order to the second server 105 (the server of the payment platform). After thesecond server 105 transfers the top-up digital asset from the account of the first user to the account of the first server according to the top-up order, thesecond server 105 sends a successful top-up message to theterminal 101 of the first user identity and thefirst server 104. After receiving the message of successful recharging, thefirst server 104 generates recharging transaction data and sends the recharging transaction data to theblockchain network 103. Wherein the load transaction data indicates to transfer the load digital asset from the wallet address of the first server to the wallet address of the first user identification. Theblockchain network 103 may verify and store the load transaction data. After receiving the message of successful recharging sent by thesecond server 105, theterminal 101 of the first user identifier may view the recharging transaction data in theblockchain network 103.

Theterminal 101 of the first user identifier may purchase the authorization information corresponding to the first target object identifier after completing the recharging of the wallet address of the first user identifier. First, theterminal 101 of the first user identifier receives a purchase operation instruction for purchasing authorization information corresponding to the first target object identifier, then generates first transaction data according to the purchase instruction, and uploads the first transaction data to theblockchain network 103. Wherein the first transaction data indicates a transfer of the transaction digital asset from the first user-identified wallet address to the second user-identified wallet address. Wherein the wallet address of the second user identification indicates a wallet address used by the second user to conduct transactions (payments, collections) of digital assets in the blockchain network. Next, theterminal 101 of the first user identifier sends a target order for purchasing authorization information corresponding to the first target object identifier to thefirst server 104, where the target order includes the first user identifier, the second user identifier, the first target object identifier, and the hash value of the first transaction data. The first user identifier may refer to a public key of the first user, and the second user identifier may refer to a public key of the second user. When thefirst server 104 receives the target order, it searches whether the hash value of the first transaction data exists in theblockchain network 103 according to the hash value of the first transaction data carried in the target order. When thefirst server 104 finds the hash value of the first transaction data from theblockchain network 103, it proves that the first transaction data is already stored in the blockchain network, which indicates that the first user has paid the second user for purchasing the digital asset corresponding to the authorization information corresponding to the first target object identifier. At this time, thefirst server 104 sends the authorization information corresponding to the first target object identifier to theterminal 101 of the first user identifier.

After the first transaction data is stored in theblockchain network 103, theterminal 102 of the second subscriber identity may also view the first transaction data in theblockchain network 103, and in turn, may view the digital assets remaining from the wallet address of the second subscriber identity. Thus, theterminal 102 of the second subscriber identity may send a cash-out request to thefirst server 104. Upon receiving the cash-out request,first server 104 generates cash-out transaction data from the cash-out request, the cash-out transaction data indicating that the cash-out digital asset is to be transferred from the wallet address of the second user identification to the wallet address of the first server. Thefirst server 104 then uploads the cash-out transaction data to theblockchain network 103. After theblock chain network 103 verifies and stores the cash withdrawal transaction data, thefirst server 104 generates a cash withdrawal order according to the cash withdrawal transaction data and sends the cash withdrawal order to thesecond server 105, and after the second server receives the cash withdrawal order, the second server transfers the designated cash withdrawal digital assets of the cash withdrawal order from the account of the first server to the account of the second user and sends the cash withdrawal result to thefirst server 104 and theterminal 102 of the second user identifier.

Alternatively, theterminal 101 of the first subscriber identity and theterminal 102 of the second subscriber identity may be smart devices such as a mobile phone, a computer, a smart watch, and the like, which is not limited herein.

Alternatively, the client based on the application platform may be an APP, an applet, a web page, or the like, and is not limited herein.

Based on the above description, an embodiment of the present invention proposes a data processing method that can be executed by the above-mentioned data processing system. The terminal of the first subscriber identity may be a terminal 101 of the first subscriber identity, the terminal of the second subscriber identity may be a terminal 102 of the second subscriber identity, the blockchain network may be ablockchain network 103, the first server may be afirst server 104, and the second server may be asecond server 105. The terminal of the first subscriber identity, the terminal of the second subscriber identity and the first server are all nodes in the block chain network. The data processing method can comprise the following partial or whole steps:

block chain user registration:

before a user logs in and carries out authorization information transaction corresponding to a first target object identifier, a terminal of a first user identifier, a terminal of a second user identifier, and a first server need to be registered first.

After the client is installed on the terminal of the first user identifier, based on that when the client receives a registration request of the first user, the terminal of the first user identifier uses an asymmetric encryption algorithm, such as an ECC (elliptic curve encryption algorithm), to create a key pair of the first user. The key pair comprises a public key of the first user and a private key of the first user, the private key of the first user is used for data signature, and the public key of the first user is used for data encryption. At this point, the first user registration is complete.

The terminal of the second subscriber identity and the first server are both registered in the above-described manner.

A first user (buyer) logs in:

the terminal of the first user identifier outputs a public key of the first user and a private key of the first user based on the client, so that the first user logs in by taking the public key of the first user as an account and the private key of the first user as a password. Fig. 2 is a schematic flowchart of a login method according to an embodiment of the present invention, and as shown in fig. 2, the method may include all or part of the following steps:

s201, the terminal of the first user identification receives an input account and a password.

The terminal of the first user identification can receive an account number and a password input by the first user based on the client.

S202, the terminal of the first user identification calculates whether the input account can be obtained according to the input password.

After receiving the input account and password, the terminal of the first user identifier generates an asymmetric encryption algorithm with the same public key of the first user by adopting the private key of the first user, and verifies whether the input password can obtain the input account through the asymmetric encryption algorithm. Executing steps S2021-S2024 when the input account is obtained according to the input password; if the input account is not obtained from the input password, step S203 is executed.

S2021, the terminal of the first user identifier sends a login request to the first server.

The login request carries an account of the first user.

S2022, when receiving the login request sent by the terminal of the first user identifier, the first server verifies whether the account of the first user is a node in the block chain.

S2023, the first server sends login response information to the terminal of the first user identifier.

The login response information is used for prompting whether the first user successfully logs in. When the first server verifies that the account of the first user is a node in the block chain, login response information of successful login is sent to the terminal of the first user identifier; and when the account number of the first user is verified not to be one node in the block chain, the first server sends login response information of login failure to the terminal of the first user identifier.

S2024, the terminal of the first user identifier receives the login response information sent by the first server.

Optionally, in step S2022, after receiving the login request sent by the terminal of the first user identifier, the first server may also send login information of a login page to the terminal of the first user identifier, for example, an account of the first user, identifiers of a plurality of target objects, a target object recommended to the first user, and the like. Step S2024 forms a login page at the terminal of the first user identifier after receiving the login information sent by the first server, and further outputs the login information of the login page to the first user.

Alternatively, step S203 may not be necessary.

The seller uploads authorization information corresponding to the target object identifier:

and the terminal of the second user identifier logs in according to the login mode of the terminal of the first user identifier, so that data interaction is carried out with the first server. For example, the terminal of the second user identifier uploads authorization information corresponding to the first target object identifier to the first server. Fig. 3 is a flowchart of a method for uploading authorization information corresponding to a target object identifier according to an embodiment of the present invention. The method flow is described by taking an example that a terminal of a second user identifier uploads authorization information corresponding to a first target object identifier, as shown in fig. 3, the method may include some or all of the following steps.

S301, the terminal of the second user identification generates second transaction data, and the second transaction data comprises authorization information corresponding to the first target object identification encrypted by the public key of the first server.

Before S301 is executed, the terminal of the second user identifier requests the public key of the first server from the first server through the blockchain network, so as to encrypt the authorization information corresponding to the first target object identifier by using the public key of the first server.

And after the terminal of the second user identifier receives the public key of the first server sent by the first server, generating second transaction data according to the authorization information corresponding to the first target object identifier received by the terminal of the second user identifier and the public key of the first server. The embodiment of the application provides two implementation modes for generating the second transaction data.

Implementation mode (one):

referring to fig. 4, fig. 4 is a schematic diagram illustrating a method for generating second transaction data according to an embodiment of the present disclosure. As shown in fig. 4, the specific process includes: firstly, a terminal of a second user identifier receives input or generated authorization information corresponding to a first target object identifier, and performs hash operation on the authorization information corresponding to the first target object identifier to obtain a hash value of the authorization information corresponding to the first target object identifier; secondly, encrypting the authorization information corresponding to the first target object identification and the hash value of the authorization information corresponding to the first target object identification through the public key of the first server to obtain second transaction data; then, carrying out hash operation on the second transaction data to obtain a hash value of the second transaction data; and finally, signing the second transaction data and the hash value of the second transaction data through a private key of a second user.

Implementation mode (b):

referring to fig. 5, fig. 5 is a schematic diagram illustrating another method for generating second transaction data according to an embodiment of the present disclosure. As shown in fig. 5, first, a terminal of a second user identifier receives input or generated authorization information corresponding to a first target object identifier, and encrypts the authorization information corresponding to the first target object identifier through a public key of a first server to obtain second transaction data; secondly, performing hash operation on the second transaction data to obtain a hash value of the second transaction data; and finally, signing the second transaction data and the hash value of the second transaction data through a private key of a second user. The authorization information corresponding to the first target object identifier may also be referred to as authorization information of the first target object, which refers to authorization information that authorizes use of the first target object, for example, an activation code of an application program.

Optionally, without being limited to the implementation manners of generating the second transaction data given in the foregoing implementation manner (a) and implementation manner (b), the second transaction data may also be in other forms that ensure that the authorization information corresponding to the first target object identifier is securely sent to the first server without being tampered and leaked, which is not limited herein.

S302, the terminal of the second user identification uploads second transaction data to the blockchain network.

And after receiving the second transaction data, the node in the block chain network verifies and stores the second transaction data. In one implementation, a node in the blockchain network receives second transaction data signed by a private key of a second user and a hash value of the second transaction data. Firstly, decrypting second transaction data signed by a private key of a second user and a hash value of the second transaction data through a public key of the second user, and verifying that the second transaction data and the hash value of the second transaction data come from a terminal of a second user identifier; secondly, performing hash operation on the received second transaction data to obtain a hash value, comparing whether the hash value is the same as that of the received second transaction data, verifying whether the hash values of the second transaction data and the second transaction data are falsified, and if the hash values are the same, verifying that the hash values of the received second transaction data and the second transaction data are not falsified; and finally, under the condition that the verification is passed, taking the public key of the second user, the second transaction data and the hash value of the second transaction data as an uploading record to be temporarily stored in the transaction pool. Other nodes in the blockchain also verify and temporarily store each received upload record in the manner described above. And at set intervals, the recording node in the block chain network takes the public key of the second user from the terminal of the second user identifier, the second transaction data and the hash value of the second transaction data as an upload record and packs and stores the upload record and other temporary records in the transaction pool in a new block.

In some embodiments, a specific implementation of the second transaction data is obtained by encrypting, by the public key of the first server, the authorization information corresponding to the first target object identifier: and encrypting the authorization information corresponding to the first target object identification and the first target object through the public key of the first server to obtain second transaction data. When the blockchain network stores the second transaction data, the first target object is also stored in the blockchain network. The property that the block chain storage data is difficult to be tampered can be used for performing copyright forensics on the first target object. In one implementation: when the second user needs the copyright certification of the first target object, the upload record can be acquired from the blockchain network to certify the ownership of the first target object by the second user. When the second user finds that the second target object owned by the third user is similar to the first target object owned by the second user, it may obtain evidence from the blockchain network, and obtain an upload record of the first target object recorded in the blockchain block: a public key of the second user, the second transaction data, a hash value of the second transaction data, a timestamp, etc. The uploading record comprises a public key of the second user to prove that the uploading record is uploaded by the second user, and the time stamp proves the uploading time of the second user. If the time stamp of the uploading record of the first target object uploaded by the second user is earlier than the time stamp of the uploading record of the second target object uploaded by the third user, the first target object can be proved to be owned by the second user, and the second target object which is the same as or similar to the first target object is suspected to be infringed.

S303, the first server receives the second transaction data from the terminal of the second user identifier.

S304, the first server decrypts the authorization information corresponding to the encrypted first target object identifier through a private key of the first server, and stores the authorization information corresponding to the first target object identifier.

And the first server receives second transaction data from the terminal of the second user identifier, and stores the authorization information corresponding to the first target object identifier obtained by decryption after verifying that the second transaction data is from the terminal of the second user identifier and is not tampered. Specifically, after receiving the second transaction data signed by the private key of the second user and the hash value of the second transaction data, the first server verifies whether the hash value of the second transaction data and the hash value of the second transaction data are from the terminal identified by the second user and are tampered or not according to the way that the node in the block chain verifies the received data. In case of passing the verification:

in the form of the second transaction data targeted by the implementation manner (i), first, the first server performs hash operation on the data obtained by decryption to obtain a predicted hash value; and secondly, storing the authorization information corresponding to the first target object identification when the predicted hash value is the same as the hash value of the authorization information corresponding to the first target object identification. Specifically, the method comprises the following steps: the first server decrypts the second transaction data through a private key of the first server to obtain authorization information corresponding to the first target object identifier and a hash value of the authorization information corresponding to the first target object identifier, then performs hash operation on the authorization information corresponding to the first target object identifier to obtain a predicted hash value, compares the predicted hash value with the hash value of the authorization information corresponding to the decrypted first target object identifier to determine whether the predicted hash value is the same as the hash value of the authorization information corresponding to the decrypted first target object identifier, if so, proves that the authorization information corresponding to the first target object identifier is not tampered in the uploading process again, and then the first server stores the authorization information corresponding to the decrypted first target object identifier. The implementation mode (I) is that the safety of the authorization information corresponding to the first target object identification in the uploading process is improved through the comparison and verification of the hash values twice; and the authorization information corresponding to the first target object identification is prevented from being stolen by other users in the uploading process by encrypting the public key of the first server and only decrypting the public key of the first server.

In the form of the second transaction data targeted by the implementation manner (b), the first server decrypts the second transaction data by using the private key of the first server to obtain the authorization information corresponding to the first target object identifier, and then the first server stores the authorization information corresponding to the first target object identifier obtained by decryption. Through one-time Hash verification, the authorization information corresponding to the first target object identifier is prevented from being tampered in the process of uploading to the first server; and the authorization information corresponding to the first target object identification is prevented from being stolen by other users in the uploading process by encrypting the public key of the first server and only decrypting the public key of the first server.

In one implementation, if the verification of the blockchain network fails or the verification of the first server fails to pass the second transaction data, the authorization information corresponding to the second transaction data and the first target object identifier carried by the second transaction data cannot be stored.

Optionally, the authorization information corresponding to the first target object identifier may further include the first target object identifier, a profile of the authorization information corresponding to the first target object identifier, and other information related to the authorization information corresponding to the first target object identifier.

In one implementation, after the first server stores the authorization information corresponding to the first target object identifier, the first server sends, to the terminal of the first user identifier, the first target object identifier, the public key of the second user, the transaction digital asset, and other information related to the authorization information corresponding to the first target object identifier. The terminal of the first user identifier receives and outputs the first target object identifier, the public key of the second user, the transaction digital asset and the like sent by the first server, so that the first user can purchase the authorization information corresponding to the first target object identifier based on the terminal of the first user identifier.

Optionally, the other terminal, including the terminal of the second user identifier, may also receive information related to the authorization information corresponding to the first target object identifier, such as the first target object identifier, the public key of the second user, and the transaction digital asset, sent by the first server, so that the user of the other terminal may view and purchase the authorization information corresponding to the first target object identifier.

User recharge:

the following takes the first user as an example to explain the specific implementation of recharging. And when the terminal of the first user identifier receives and outputs the first target object identifier, the public key of the second user and the transaction digital asset, the first user can purchase the authorization information corresponding to the first target object identifier. The terminal of the first user identifier may further receive an input recharging operation, so that the wallet address of the first user identifier has a sufficient balance to be used for paying the authorization information corresponding to the first target object identifier. Referring to fig. 6, fig. 6 is a flowchart of a recharging method according to an embodiment of the present invention, and as shown in fig. 6, the method may include the following steps:

s601, when the terminal of the first user identification successfully charges the rechargeable digital assets, the first server generates rechargeable transaction data, and the rechargeable transaction data indicates that the rechargeable digital assets are transferred from the wallet address of the first server to the wallet address of the first user identification.

And the terminal of the first user identification performs the chain recharging on the recharging digital assets, and then sends the recharging result to the first server under the condition of successful recharging. In one implementation: firstly, a terminal of a first user identification receives recharging information input by a recharging interface and sends the recharging information to a first server; secondly, the first server generates a recharging order according to the recharging information and sends the recharging order to a terminal of the first user identification; and finally, the terminal of the first user identifier sends the recharging order to a server (a second server) of the payment platform according to the input payment platform, and the server of the payment platform completes payment according to the recharging order, namely the appointed recharging digital assets are transferred from the account of the first user to the account of the first server. And under the condition of successful recharging, the server of the payment platform sends the recharging result to the first server and the terminal of the first user identifier. At this time, the terminal of the first user identifier is successful in recharging the rechargeable digital assets.

And after receiving the recharging result of successful recharging, the first server generates recharging transaction data according to the recharging result, wherein the recharging transaction data indicates that the recharging digital assets are transferred from the wallet address of the first server to the wallet address of the first user identifier.

S602, the first server sends the recharging transaction data to the block chain network.

Firstly, the first server performs hash operation on the recharging transaction data to obtain a hash value of the recharging transaction data; secondly, the first server signs the recharging transaction data and the hash value of the recharging transaction data by using the private key of the first server; and finally, uploading the recharging transaction data signed by the public key of the first server and the private key of the first server and the hash value of the recharging transaction data to the blockchain network.

When one node in the block chain network receives the recharging transaction data and the hash value of the recharging transaction data signed by the public key of the first server and the private key of the first server: firstly, the public key of the first server decrypts the recharging transaction data signed by the private key of the first server and the hash value of the recharging transaction data, and proves that the recharging transaction data come from the first server; secondly, carrying out hash operation on the recharging transaction data to obtain a hash value, comparing the hash value with the hash value of the recharging transaction data from the first server, and if the hash value is consistent with the hash value of the recharging transaction data from the first server, determining that the recharging transaction data is not tampered; finally, when the verification is passed (it can be considered that the balance of the wallet address of the first server is infinite, so that it is not necessary to verify whether the balance of the wallet address of the first server is sufficient), the public key of the first server from the first server, the recharge transaction data and the hash value of the recharge transaction data are temporarily stored in the transaction pool as a recharge record. And other nodes in the block chain network also carry out verification and temporarily store each received recharging record according to the mode. At set intervals, the record node in the block chain network takes the public key of the first server from the first server, the recharge transaction data and the hash value of the recharge transaction data as a recharge record and packs and stores the recharge record and other records temporarily stored in the transaction pool in a new block.

And (3) purchasing the application program:

when the wallet address of the first user identifier has enough balance to purchase the authorization information corresponding to the first target object identifier, the terminal of the first user identifier can upload first transaction data of the authorization information corresponding to the second target object identifier purchased by the terminal of the second user identifier to the blockchain network. In one implementation, a terminal of a first user identifier receives a purchase operation for authorization information corresponding to a first target object identifier, and generates first transaction data according to the purchase operation, where the first transaction data may include a wallet address of the first user identifier, a wallet address of a second user identifier, a purchase digital asset, and so on. Referring to fig. 7, fig. 7 is a flowchart illustrating a purchasing method according to an embodiment of the present disclosure. The method can comprise the following partial or whole steps:

And under the condition that the verification is passed, taking the public key of the first user from the terminal of the first user identifier, the first transaction data and the hash value of the first transaction data as a transaction record to be temporarily stored in the transaction pool. Other nodes in the blockchain network also validate each received transaction record in the manner described above. At set intervals, a recording node in the block chain network takes the public key of the first user from the terminal of the first user identifier, the first transaction data and the hash value of the first transaction data as a transaction record and packs and stores the transaction record and other records temporarily stored in the transaction pool in a new block.

S702, the terminal of the first user identification sends a target order to the first server, wherein the target order comprises the first user identification, the second user identification, the first target object identification and the hash value of the first transaction data.

After uploading the public key of the first user, the first transaction data encrypted by the private key of the first user, and the hash value of the first transaction data to the blockchain network, the terminal of the first user identifier further sends a target order to the first server, where the first user identifier indicates an identifier of the first user, and may be, for example, the public key of the first user; the second user identity indicates an identity of the second user, which may be, for example, a public key of the second user; the first target object identifier is used for uniquely identifying the first target object, for example, a unique serial number is set for an application program in a transaction process; the hash value of the first transaction data is obtained by performing a hash operation on the first transaction data.

And after receiving the target order, the first server analyzes the target order to obtain the hash value of the first transaction data.

S704, the first server searches the first transaction data from the blockchain network according to the hash value of the first transaction data.

When the first server finds the first transaction data in the blockchain network, step S705 is executed; when the first server does not find the first transaction data in the blockchain network, the first server may ignore the target order sent by the terminal of the first user identifier, or send a message indicating that the terminal of the first user identifier does not complete payment to the terminal of the first user identifier, and the first server may also perform other operations, which is not limited herein.

S705, when the first server finds the first transaction data in the blockchain network, the first server sends the authorization information corresponding to the first target object identifier to the terminal of the first user identifier.

In the process of performing the hash operation on the first transaction data, an order number, a transaction number, a random character or the like may be added on the basis of original information (i.e., information indicating that the transaction digital asset is transferred from the wallet address of the first user identifier to the wallet address of the second user identifier).

And searching a transaction record aimed by the target order in the blockchain network according to the received hash value of the first transaction data, namely whether the hash value of the first transaction data is written into the blockchain, and if the first server can search the hash value of the first transaction data from the blockchain, proving that the first transaction data is stored into the blockchain, and the terminal of the first user identification completes payment on the target order, namely the transaction digital asset is transferred from the wallet address of the first user identification to the wallet address of the second user identification. At this time, the first server sends the authorization information corresponding to the first target object identifier to the terminal of the first user identifier. The authorization information corresponding to the first target object identifier may be an activation code, an authorization code, an extraction link, and the like, which authorize use of the authorization information corresponding to the first target object identifier, and is not limited herein.

S706, the terminal of the first user identifier receives authorization information corresponding to the first target object identifier sent by the first server.

Optionally, after receiving the target order from the terminal of the first user identifier, the first server may also directly send the first target object to the terminal of the first user identifier, which is not limited herein.

According to the purchasing method, the terminal of the first user identifier uploads the transaction data to the blockchain network, so that other servers or terminals in the blockchain network can verify and store the transaction data, a centralized platform is not required to manage the transaction data generated in the transaction process, and the transaction data is transparent and cannot be tampered.

User cash withdrawal:

after the terminal of the first user identifier performs the purchase of the authorization information corresponding to the first target object identifier, the digital asset of the wallet address of the first user identifier is transferred to the wallet address of the second user identifier, and at this time, the terminal of the second user identifier may receive an input cash withdrawal operation, that is, the digital asset in the wallet address of the second user is converted into the digital asset in the account of the second user on the payment platform. Referring to fig. 8, fig. 8 is a flowchart of a method for presenting a presentation according to an embodiment of the present invention, as shown in fig. 8, the method includes the following steps:

The first server generates cash withdrawal transaction data according to the cash withdrawal request.

S803, the first server uploads cash-out transaction data to the blockchain network, the cash-out transaction data indicating that the cash-out digital asset is to be transferred from the wallet address of the second user identification to the wallet address of the first server.

Firstly, the first server carries out hash operation on the cash withdrawal transaction data to obtain a hash value of the cash withdrawal transaction data; secondly, signing the cash withdrawal transaction data and the hash value of the cash withdrawal transaction data through a private key of the first server; and finally, uploading the public key of the first server, the cash withdrawal transaction data signed by the private key of the first server and the hash value of the cash withdrawal transaction data to the blockchain network.

And when the verification passes, temporarily storing the public key of the first server from the first server, the cash withdrawal transaction data and the hash value of the cash withdrawal transaction data in the transaction pool as a cash withdrawal record. And other nodes in the block chain network also carry out verification and temporarily store each received cash-out record according to the mode. At set intervals, a recording node in the block chain network takes the public key of the first server from the first server, the cash-out transaction data and the hash value of the cash-out transaction data as a cash-out record and packs and stores the cash-out record and other records temporarily stored in the transaction pool in a new block.

S806, when the first server finds the cash withdrawal transaction data from the blockchain network, the cash withdrawal digital asset is transferred from the account of the first server to the account of the second user.

When the first server finds the hash value of the cash-out transaction data in the transaction record of the blockchain network according to the hash value of the cash-out transaction data, the fact that the cash-out transaction data is stored in one block is proved. At this point, the first server transfers the cash-out digital asset from the account of the first server to the account of the second user. In one implementation, a first server sends a cash-out order to a second server. And after receiving the withdrawal order, the second server transfers the withdrawal digital assets from the account of the first server to the account of the second user according to the withdrawal order, and under the condition of successful withdrawal, the second server sends information of successful withdrawal to the first server and the second user.
