The blockchain correlation technique is described in association with fig. 1 a-1 b as follows:

1. Blockchain system:

the data processing system according to the embodiments of the present application may be a distributed system (i.e., a block link point system) formed by connecting a plurality of nodes through a network communication. The related art related to blockchain node systems is described in detail below with reference to fig. 1 a:

referring to fig. 1a, fig. 1a is a schematic structural diagram of a blockchain node system according to an embodiment of the present application. The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is mainly used for sorting data according to time sequence, encrypting the data into an account book, preventing the account book from being tampered and forged, and simultaneously verifying, storing and updating the data. The blockchain is essentially a de-centralized database, each node in the database stores an identical blockchain, and the blockchain network comprises a consensus node, and the consensus node is responsible for the consensus of the blockchain whole network.

The blockchain node system as shown in fig. 1a may correspond to a blockchain network that may include, but is not limited to, a blockchain network to which a federated chain, a public chain, a private chain, and the like correspond. A blockchain node system refers to a system for sharing data between blockchain nodes, and the blockchain node system may include a plurality of nodes, where the plurality of nodes may include a node 101, a node 102, a node 103, a …, and a node 10n, and the node 101, the node 102, the node 103, …, and the node 10n may be collectively referred to as blockchain nodes. It may be appreciated that the communication connection may be established between the nodes by an information connection manner, and the information connection is not limited to a specific connection manner, for example, may be directly or indirectly connected by a wired communication manner, may be directly or indirectly connected by a wireless communication manner, and may also be connected by other connection manners, which is not limited herein.

Each node (node 101, node 102, node 103, …, node 10 n) in the blockchain node system may receive input information (e.g., node 101 may receive a preprocessing request for a digital collection to be issued sent by a computer device (e.g., a terminal device or a server), or, for example, node 101 may receive a digital collection uplink request sent by a computer device (e.g., a terminal device or a server), etc.) during normal operation, and maintain shared data in the data sharing system based on the received input information. In order to ensure the information intercommunication in the data sharing system, information connection can exist between each node in the data sharing system, and the nodes can transmit information through the information connection. For example, when any node in the data sharing system receives input information, other nodes in the data sharing system acquire the input information according to a consensus algorithm, and store the input information as data in the shared data, so that the data stored on all nodes in the data sharing system are consistent.

For each node (node 101, node 102, node 103, …, node 10 n) in the blockchain node system shown in fig. 1a, there is a node identification corresponding thereto, and each node in the blockchain node system may store the node identifications of other nodes in the blockchain node system so as to subsequently broadcast the generated blocks to other nodes in the blockchain node system according to the node identifications of the other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list.

The node identifier may be an IP (Internet Protocol, protocol of interconnection between networks) address, and any other information that can be used to identify the node, and the IP address is only illustrated in table 1.

Node name	Node identification
		Node 1	000.000.000.000

The blockchain is composed of a plurality of blocks, referring to fig. 1b, fig. 1b is a schematic structural diagram of a blockchain according to an embodiment of the present application. As shown in fig. 1b, the blockchain is composed of a plurality of blocks, the starting block comprises a block head and a block body, the block head stores an input information characteristic value, a version number, a time stamp and a difficulty value, and the block body stores input information; the next block of the starting block takes the starting block as a father block, the next block also comprises a block head and a block body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the father block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.

It will be appreciated that a Block (Block) is a packet of data carrying transaction data over a blockchain network, and is a data structure that is time stamped and hashed with the previous Block, the Block being authenticated and the transactions in the Block being determined by the network's consensus mechanism. In one possible implementation, the present application may place the process of issuing digital collections on a blockchain.

In one possible implementation, the above-mentioned data processing scheme is further illustrated by way of example with respect to blockchain node 201 and computer device 202. Specifically, the blockchain node 201 may obtain a preprocessing request sent by the computer device 202 for a digital collection to be issued, where the preprocessing request carries a digital collection locking value, where the digital collection locking value is determined according to a target contract identifier and a target issue address, and the target contract identifier is used to indicate issuing of the target digital collection; the blockchain node 201 responds to the preprocessing request, generates locking transaction data comprising a target contract identification and a target issuing address, and performs uplink processing on the locking transaction data; blockchain node 201 obtains a digital collection uplink request that includes: the digital collection locking value, the contract identification to be verified, the issue address to be verified, the digital collection uplink request being issued by the computer device 202 after confirming that the locking transaction data is successfully uplink; if the blockchain node 201 verifies that the contract identification to be verified and the issue address to be verified pass based on the digital collection locking value, issuing the digital collection indicated by the contract identification to be verified into the issue address to be verified.

It can be understood that, as the implementation object of the present application can be known, along with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided by the embodiment of the present application is applicable to similar technical problems.

Based on the above description of the data processing scheme and the data processing system, the embodiment of the application provides a blockchain data processing method. Referring to fig. 3, fig. 3 is a flowchart of a blockchain data processing method provided in an embodiment of the present application, where the blockchain data processing method may be executed by a blockchain node (e.g., a terminal device or a server) in the data processing system mentioned in fig. 2. The blockchain data processing method may include the following steps S301 to S304:

s301, acquiring a preprocessing request aiming at a digital collection to be issued, wherein the preprocessing request carries a digital collection locking value, the digital collection locking value is determined according to a target contract identifier and a target issuing address, and the target contract identifier is used for indicating issuing of the target digital collection.

In this application, a digital collection is a rights, equity credential for a virtual digital commodity, and may include, but is not limited to: digital drawings, pictures, music, video, 3D models, and the like. Digital collections may be issued based on digital collection protocols.

In one possible implementation manner, before the block chain node obtains the preprocessing request for the digital collection to be issued, the block chain node may also obtain the object identity identifier of the target object sent by the computer device, where the object identity identifier is generated after the real name authentication server receives the identity information of the target object and successfully performs real name authentication on the identity information of the target object. The computer device then associates the object identification with a target issue address corresponding to the target object. Wherein the real name authentication comprises at least one of the following: and verifying the validity of the identity information and verifying the security of the identity information.

In a possible implementation manner, the block link point obtains the object identity of the target object sent by the computer device, and may specifically include the following procedures: the target object can perform real-name authentication by logging in a real-name authentication applet (wherein the applet refers to an application program which is free from installation), and then the real-name authentication applet can acquire identity information recorded by the target object in the real-name authentication applet. The real-name authentication applet may then send the IDentity information of the target object to a real-name authentication server, which may be, for example, a Decentralised IDentity (DID) server. After receiving the identity information submitted by the target object, the DID server may invoke a third party platform (e.g., an operator) interface to perform real-name authentication on the identity information of the target object, and if the real-name authentication is successful, generate an object identity (DID identity) of the target object, and send the real-name authentication success notification message to the computer device, so that the computer device sends the DID identity of the target object to the blockchain node.

Specifically, real-name information of the target object may be obtained by invoking a third party platform (e.g., operator) interface. Then, real-name authentication can be performed on the identity information of the target object based on the acquired real-name information, which specifically includes: comparing each item of specific information in the real-name information with each item of specific information in the identity information respectively, if the specific information is the same as the specific information in the identity information, determining that the real-name authentication of the target object is successful, and generating a real-name authentication success notification message; if any of the items are different, determining that the authentication of the real name of the target object fails.

Please refer to fig. 4, fig. 4 is a schematic diagram of a data acquisition scenario provided in the embodiment of the present application. As shown in fig. 4, the real-name authentication server may send an authorization request to the computer device used by the target object before acquiring the identity information of the target object. Then, after the computer device used by the target object receives the authorization request, an authorization interface (e.g., interface S400 shown in fig. 4) may be displayed in the computer device. Specifically, if the target object clicks the validation control 401 in the authorization interface S400, the real-name authentication server is allowed to acquire identity information on behalf of the target object. In this way, when the real-name verification server needs to acquire the identity information of the target object, authorization needs to be requested to the target object, and after the target object is successfully authorized, the party can acquire the corresponding identity information, so that the privacy of the identity information of the target object can be ensured.

In one possible implementation manner, the computer device associates the object identity with a target issue address corresponding to the target object, and specifically includes the following procedures: firstly, receiving an identity registration request sent by a real-name verification server, wherein the identity registration request carries an object identity of a target object; then, responding to the identity registration request, obtaining a blockchain address of the target object, and taking the blockchain address as a target issuing address; and associating the object identity with a target issuing address corresponding to the target object. The blockchain address may be an account address in a blockchain determined based on a public key of the target object, and specifically may be determined by calculating a hash value of the public key of the target object through a digest algorithm (for example, SHA-256 algorithm, SHA-512 algorithm, etc.). It will be appreciated that the blockchain address of the target object is unique across the blockchain.

In this way, in the process of issuing the digital collection, real-name verification is performed on the identity information of the target object in advance, so that the reliability and the safety in the process of issuing the digital collection can be improved.

In one possible implementation, the digital collection lock value may be determined by the computer device based on the target contract identification, the target issue address, and then the computer device generates a preprocessing request based on the digital collection lock value and sends the preprocessing request to the computer device. In another possible implementation manner, the preprocessing request carries the target contract identifier and the target release address, and after the computer equipment sends the preprocessing request comprising the target contract identifier and the target release address to the computer equipment, the computer equipment determines to obtain the digital collection locking value according to the target contract identifier and the target release address. In order to ensure cheating of computer equipment, the embodiment of the application takes the example that the computer equipment generates a digital collection locking value as an example to correspondingly explain.

Specifically, the digital collection locking value is obtained by performing hash operation on the target random value, the description metadata, the target contract identification and the target release address by the computer equipment based on a hash algorithm. The target random value may be a random value obtained according to a random algorithm, for example, the target random value may be a salt value. The description metaData is used to describe attribute information of the digital collection to be released, for example, the digital collection to be released is a picture, and the attribute information corresponding to the picture may include, but is not limited to: URL (Uniform Resource Locator) links of pictures, detailed parameters of pictures (e.g. exposure, brightness, saturation), etc. The target contract identifier is determined based on a target release address, and is generated by a specific rule such as, for example, a target contract identifier tokenid= (target release address+digital stock sequential encoding). For example, the digital collection lock value may be expressed as: hash (salt, token id, metaData, address).

S302, locking transaction data comprising a target contract identification and a target issuing address is generated in response to the preprocessing request, and uplink processing is carried out on the locking transaction data.

In one possible implementation, the preprocessing request carries an identification of the computer device. The computer device may first verify the identity of the computer device in response to the preprocessing request, and if the verification passes, generate locking transaction data according to the target contract identity and the target issue address. In this way, it is possible to verify whether the computer device is a malicious node, thereby ensuring reliability and security in the data processing process.

In one possible implementation, the computer device performs the uplink processing on the locking transaction data, and may include the following procedures: performing verification processing on the locking transaction data to obtain a verification result; if the verification result is that the verification is passed, a locking success notification message is generated, and the locking success notification message is returned to the computer equipment. Wherein the lock success notification message is used for indicating that the target digital collection is issued to the target issue address. Specifically, the computer device performs verification processing on the locking transaction data, which may specifically include: first, the locking transaction data is sent to each blockchain node in the blockchain network, so that each blockchain node performs consensus processing on the locking transaction data respectively. And then, receiving the consensus result returned by each blockchain node, and determining the verification result of the locking transaction data according to the received consensus result. The verification result can include that verification is passed and verification is not passed, and if the verification is determined to be passed, a locking success notification message is generated; and if the verification is determined not to pass, generating a verification failure notification message.

S303, acquiring a digital collection uplink request, wherein the digital collection uplink request comprises the following steps: the digital collection locking value, the contract identification to be verified, the issue address to be verified, and the digital collection uplink request are sent after the successful uplink of the locking transaction data is confirmed.

It will be appreciated that if the computer device receives a lock success notification message sent by the computer device, the computer device may confirm that the lock transaction data has been successfully uplink. The computer device may then generate a digital collection upload request and send the digital collection upload request to the computer device.

In one possible implementation, the digital collection uplink request carries an identification of the computer device. The computer device responds to the digital collection uplink request, firstly, the identification of the computer device can be checked, and if the verification is passed, the step of verifying the contract identification to be verified and the issuing address to be verified based on the digital collection locking value is triggered to be executed. In this way, it is possible to verify whether the computer device is a malicious node, thereby ensuring reliability and security in the data processing process.

S304, if the contract identification to be verified and the issuing address to be verified pass verification based on the digital collection locking value, the digital collection indicated by the contract identification to be verified is issued to the issuing address to be verified.

In one possible implementation, the digital collection upload request may also include description metadata and a target random value for the digital collection to be released. The digital collection uplink request mentioned in the embodiment of the present application includes: the digital collection locking value, the contract identification to be verified, the issuing address to be verified, the description metadata of the digital collection to be issued and the target random value.

Specifically, the computer device verifies the contract identifier to be verified and the issue address to be verified based on the digital collection locking value, and specifically may include: firstly, carrying out hash operation processing on a contract identifier to be verified, an issuing address to be verified, description metadata and a target random value based on a hash algorithm to obtain a digital collection verification value. And then comparing the digital collection locking value with the digital collection verification value, and if the comparison is successful, determining that the contract identification to be verified and the issuing address to be verified pass the verification.

For example, assume that the contract identification to be verified is represented as tokenId ', the issue address to be verified is represented as address', and the digital stock lock value is represented as: hash (salt, token id, metaData, address). Then, hash operation is performed on the token id ', address', metaData, and salt based on the hash algorithm, and the obtained digital stock verification value is expressed as: hash (token, token id ', metaData, address'). If hash (salt, token id, metaData, address) =hash (salt, token id ', metaData, address'), it is determined that the contract identification to be verified and the issue address to be verified pass verification.

In one possible implementation, after determining that the contract identification to be verified, the issue address to be verified, passes verification, the computer device may also generate an issue success notification message generated after issuing the target digital collection to the issue address to be verified. Finally, the computer device may return the issue success notification message to the computer device to cause the computer device to output the target digital collection, e.g., the computer device may invoke a related applet to present the target digital collection.

Referring to fig. 5, fig. 5 is a flowchart of another blockchain data processing method according to an embodiment of the present application, where the blockchain data processing method may be executed by a computer device in the data processing system mentioned in fig. 2. The blockchain data processing method may include the following steps S501 to S504:

s501, acquiring a target contract identification and a target release address, and determining a digital collection locking value according to the target contract identification and the target release address.

In one possible implementation manner, before the computer device obtains the target contract identifier and the target issuing address, an identity verification request submitted by the target object may also be obtained, where the identity verification request carries identity information of the target object. Then, the computer device may send the authentication request to the real-name authentication server, so that the real-name authentication server performs real-name authentication on the identity information of the target object, and then generates the object identity of the target object. Finally, the computer device may send the object identity of the target object to the blockchain node to cause the blockchain node to associate the object identity with the target issue address generated for the target object.

Specifically, the specific process of real-name authentication for the identity information of the target object by the real-name authentication server may refer to the related steps in the embodiment of fig. 3, which is not described herein in detail. And when the real-name verification server needs to acquire the identity information of the target object, authorization needs to be requested to the target object, and after the target object is successfully authorized, the party can acquire the corresponding identity information, so that the privacy of the identity information of the target object can be ensured.

In one possible implementation, the computer device determines the digital collection locking value according to the target contract identification and the target release address, and may specifically include: firstly, acquiring a target random value and description metadata of a digital collection to be issued, wherein the description metadata is used for describing attribute information of the digital collection to be issued; and carrying out hash operation processing on the target random value, the description metaData (metaData), the target contract identifier (token Id) and the target issuing address (address) based on a hash algorithm to obtain a digital collection locking value. Wherein the target random value may be a random value (e.g., salt value) generated according to a random algorithm, and the generated digital stock locking value may be expressed as: hash (salt, token id, metaData, address).

S502, generating a preprocessing request aiming at the digital collection to be issued according to the digital collection locking value, sending the preprocessing request to the blockchain node so that the blockchain node responds to the preprocessing request, generating locking transaction data comprising a target contract identification and a target issuing address, and carrying out uplink processing on the locking transaction data.

In one possible implementation, the computer device may generate a pre-processing request based on the identity of the computer device and the digital collection lock value, and may then send the pre-processing request to the blockchain node. It should be noted that, the specific execution process of generating the locking transaction data including the target contract identifier and the target issue address and performing the uplink processing on the locking transaction data by the block link point in response to the preprocessing request may refer to the related steps involved in the embodiment of fig. 3, which is not described herein again.

S503, after confirming that the locking transaction data is successfully uplink, generating a digital collection uplink request, wherein the digital collection uplink request comprises: digital collection locking value, contract identification to be verified, and issue address to be verified.

Specifically, the computer device may receive a lock success notification message sent by the blockchain node, where the lock success notification message is generated after the blockchain node verifies that the locked transaction data is passed, and the lock success notification message is used to instruct the blockchain node to send the target digital stock into the target issue address. The computer device then generates a digital collection uplink request in response to the lock success notification message.

In one possible implementation, the digital collection upload request may include: digital stock locking value, contract identification to be verified, issue address to be verified, target random value, and description metadata of digital stock to be issued. Of course, the digital collection uplink request may also include an identification of the computer device, which may be used to verify the identity of the computer device, thereby ensuring the security and reliability of the computer device.

In one possible implementation manner, a locking success notification message sent by the blockchain node is received, wherein the locking success notification message is generated after the blockchain node verifies the locking transaction data, and the locking success notification message is used for indicating the blockchain node to issue the target digital collection into the target issue address; and responding to the locking success notification message, and generating a digital collection uplink request.

S504, sending the digital collection uplink request to the blockchain node, so that the blockchain node issues the digital collection indicated by the contract identification to be verified to the issuing address to be verified after the contract identification to be verified and the issuing address to be verified are verified based on the digital collection locking value.

It should be noted that, after the contract identifier to be verified and the issue address to be verified are verified based on the digital collection locking value, the blockchain node issues the digital collection indicated by the contract identifier to be verified to the issue address to be verified, and the specific execution steps may refer to the related execution steps in the embodiment of fig. 3, which is not described herein.

In the embodiment of the application, the issuing of the digital collection needs to go through two stages. First, for the first phase, the issuer of the digital collection (the computer device) need only submit one digital collection lock value to the blockchain: a hash (hash, token id, metaData, address) cannot acquire a digital collection actually issued by an issuer through the digital collection lock value, and thus cannot perform a first-aid running operation of the digital collection. Second, for the second phase, although the issuer submitted the detailed data of the collection issuance (including random numbers such as salt values) in the transaction (digital collection uplink request) in the second phase. The attacker can acquire the values by monitoring the second-stage transaction, but the issuing address where the digital collection can be issued is already locked in the first-stage transaction, i.e. the digital collection to be issued can only be issued to the designated issuing address, and the attack value cannot be taken in the first-stage transaction even though the attack value acquires a random value, so that the digital collection is issued. In this way, the reliability and the safety in the process of issuing the digital collection are ensured.

Specifically, the digital collection locking value is obtained by performing hash operation on the target random value, the description metadata, the target contract identification and the target release address by the computer equipment based on a hash algorithm; the description metadata is used for describing attribute information of the digital collection to be released, and the target contract identification is determined according to the target release address.

S7, the block chain link point carries out uplink processing on the locking transaction data.

In particular implementations, the blockchain node may generate locking transaction data including the target contract identification and the target issue address in response to the preprocessing request, and perform a uplink processing on the locking transaction data. Specifically, the blockchain node performs uplink processing on the locked transaction data, which may include: and carrying out verification processing on the locking transaction data to obtain a verification result.

S8, calling the digital collection contract to generate a locking success notification message.

Wherein the digital collection uplink request includes: the digital collection locking value, the contract identification to be verified, the issue address to be verified, and the digital collection uplink request is sent by the computer device after the locking transaction data uplink is confirmed to be successful.
