The data processing method provided by the embodiment of the present invention is mainly based on block chain technology to realize virtual object generation, transaction processing, etc.; it should be noted that block chain (Blockchain or Block chain) is a distributed database, block chain It is a series of data blocks associated with cryptographic methods. The blockchain is not stored in a specific location on the network, but distributed and stored by each client connected to the blockchain network. Usually, each The client only stores the data blocks related to itself, and the chain verifiable information between each data block;

The meaning of the blockchain is described above. When the embodiment of the present invention applies the blockchain technology to realize the generation of virtual objects, transactions, etc., it does not directly copy the existing blockchain technology, but based on games, etc. The characteristics and system architecture of network applications have been adapted and improved by corresponding means; that is, the embodiment of the present invention realizes the processing of virtual objects in network applications such as games by referring to blockchain technology, rather than directly in games, etc. Blockchain technology is replicated in a type of network application.

Optionally, FIG. 1 shows a schematic diagram of the architecture of a data processing system provided by an embodiment of the present invention. Referring to FIG. 1 , the data processing system may include: multiple application clients 10, an operation server 20, an application server 30, and a database 40 ;

Wherein, the application client 10 can be installed on user devices such as smartphones, tablet computers, and notebook computers to provide local services for network applications such as games, and one application client generally corresponds to one user (that is, one application client is generally operated by one user) ;Application client such as game client;

In the embodiment of the present invention, the operation server 20 is no longer responsible for the generation of virtual objects, transactions, etc., but retains the ability to modify application content, release application events, etc., so that the network virtual world ecology of network applications such as games can be flexible. and persistent operation; operating servers such as game operating servers;

The application server 30 can be realized by a single server, or can be realized by a server group composed of multiple servers, and can provide network services for network applications such as games; the application server is such as a game server;

Database 40 is a network database for storing user data. In an embodiment of the present invention, database 40 can store the status data of each user, and no longer store the user's virtual object data (a user's virtual object data represents each user's status data). the number of types of virtual objects, such as the amount of virtual currency, the number of various types of virtual items, etc.); taking the game network application as an example, the database is such as a game database, and the game database can store the state data of each game player (such as game Player level, attributes, etc.), while the game currency, game props and other virtual object data owned by game players are no longer stored in the game database; the database can be read and written by the operation server and application server;

In the embodiment of the present invention, multiple application clients serve as the access nodes of the blockchain network, and multiple application clients can support the blockchain network, and the user's virtual object data is stored in the block chain in the form of data blocks. In distributed storage in the block chain network, each application client generally only stores the data block corresponding to the virtual object data of its own user.

Based on the data processing system shown in Figure 1, taking the generation of virtual objects as an example, the data processing method provided by the embodiment of the present invention will be introduced below from the perspective of the first application client. The first application client can be as shown in Figure 1 Any application client in the data processing system that needs to generate a virtual object, the first application client can be operated by the first user;

FIG. 2 is a flow chart of a data processing method provided by an embodiment of the present invention. The method can be applied to the first application client. Referring to FIG. 2, the method may include:

Step S100, when the first user completes the application event, the first application client obtains the completion evidence of the first user's completion of the application event; the completion evidence includes: the completion record of the first user's completion of the application event, And the virtual object data associated with the application event.

Application events, such as application tasks, are associated with virtual objects with rewards. The completion progress of application events is affected by the user's application behavior; the specific types of application events and the virtual object data associated with rewards can be set according to actual conditions such as operations. Certainly;

Taking the game network application as an example, the application event can be a game task, the game task is associated with a rewarded game currency, and when the game task is completed, the associated game currency can be rewarded to the user who completes the game task; the user can use the game client to Control the game behavior to gradually complete the game task; correspondingly, the completion of the application event can be, for example, the game client completes the game task, kills the game monster, etc. under the influence of the user's game behavior.

After the first user completes the application event, the first application client can obtain the proof of completion of the first user's completion of the application event, so that the subsequent completion of the data block based on the completion proof of the first user's completion of the application event Generate; the completion evidence of the first user completing the application event may indicate that the first user has completed the application event and can obtain the virtual object associated with the application event; specifically, the first user completes the application event The completion evidence may include: a completion record of the first user completing the application event, and virtual object data associated with the application event;

Optionally, the completion record of the first user completing the application event may include: the first user completes the behavior record or result record of the application event; record, or, the form of the result record of the first user completing the application event indicates the completion record; the completion record of the first user completing the application event can be determined by the first application client itself, or can be determined by the application server and sent to the The first application client.

The virtual object data associated with the application event can represent the virtual object associated with the application event, such as the type and quantity of the virtual object that needs to be rewarded to the first user when the first user completes the application event, that is, the virtual object data can describe The type and quantity of virtual objects associated with application events (for example, completing an application event can reward a certain amount of virtual currency, and/or, a certain number of virtual items, etc.);

Optionally, the virtual object data associated with the application event may be set according to actual conditions such as operation.

Optionally, the first application client can determine the virtual object data associated with the application event through the application event configuration file (taking the application event as a task as an example, the application event configuration file such as the task configuration file, etc.); the application event configuration file can record There are application event completion requirements, completion rewards (completion rewards can carry associated virtual object data), etc.; the application event configuration file can be stored locally on the first application client, or it can be the first application client to communicate with the application server. Obtained when interactively receiving application events that need to be completed;

Optionally, after the first user completes the application event, the first application client may send a notification to the application server that the first user completes the application event. Determine the associated virtual object data, determine the virtual object data associated with the application event, and then notify the first application client, so that the first application client determines the virtual object data associated with the application event.

Step S110, the first application client generates a data block corresponding to the virtual object data according to the completion evidence, and carries the completion record and indication information indicating the virtual object data in the data block .

Optionally, a data block can correspond to any type and any number of virtual objects, such as a data block can correspond to any number of virtual currencies;

After the first application client obtains the completion proof that the first user completes the application event, the completion proof serves as a zero-knowledge proof of data block generation, which can trigger the first application client to generate a data block; but the generated The data block should correspond to the virtual object data (that is, the type and quantity of the virtual object corresponding to the generated data block can correspond to the virtual object data associated with the application event), that is, although the data block can correspond to Any type and any number of virtual objects, but the first application client can only generate data blocks corresponding to the virtual object data rewarded for completing the application event under normal processing logic;

The generation method of the data block can refer to the introduction in the blockchain white paper, including the hashing of the previous data block and the construction of the hash tree. The embodiment of the present invention does not pay attention to how to generate the data block. Any technology that can generate data blocks can be applied; however, in order to facilitate subsequent verification of the validity of the generated data blocks, the generated data blocks should carry the completion record of the first user completing the application event and indicate the application event An indication of the associated virtual object data so that other application clients can verify the data block.

Optionally, the indication information indicating the virtual object data may be the virtual object data itself, or may be a corresponding identifier of the virtual object data, and the corresponding identifier can match the virtual object data.

Step S120, the first application client adds the signature information of the first user to the data block.

The signature information corresponding to the first user can uniquely identify the first user, and can be regarded as the identity of the first user. By adding the signature information corresponding to the first user to the generated data block, all A tag of the first user is added to the generated data block.

Step S130, the first application client broadcasts the data block added with the signature information to the blockchain network; the blockchain network is accessed by multiple application clients.

The application client serves as the access node of the blockchain network, and multiple application clients can form a blockchain network; after the first application client generates a data block, it can add the data block to the blockchain, and the data The validity of the block needs to be recognized by other application clients in the blockchain network. Therefore, after the first application client generates a data block, it needs to broadcast to the blockchain network, and other application clients will verify the data block. validity is verified.

In the data processing method provided by the embodiment of the present invention, when the first user completes the application event, the first application client can obtain the completion proof that the first user completes the application event, and the completion proof can indicate that the first user has completed the application event. event, and can obtain the virtual object data rewarded by the application event, that is, the completion evidence includes: the completion record of the first user completing the application event, and the virtual object data associated with the application event; thus the second An application client can generate a data block corresponding to the rewarded virtual object data according to the completion evidence, and carry the completion record and indication information indicating the virtual object data in the data block; Furthermore, the first application client can add the signature information corresponding to the first user to the data block, and then broadcast the data block with the signature information added to the block chain network, so that The application client verifies the validity of the data blocks, and realizes the generation of virtual objects with blockchain technology.

The data processing method provided by the embodiment of the present invention can realize the generation of virtual objects according to the block chain technology. The generation of virtual objects is determined by the user's behavior of completing the application event, and the first user obtained by the user to complete the application event completes the described The completion evidence of the application event realizes the mining of the data block corresponding to the virtual object data associated with the application event locally on the application client; Through the generation and presentation of data blocks, the resource overhead of the server is greatly reduced; at the same time, the data blocks can be distributed and stored in the application client of the blockchain network, effectively avoiding the intrusion or failure of the operation server , the resulting loss of user assets greatly improves the reliability of virtual object processing.

In the data processing method provided by the embodiment of the present invention, the generation of virtual objects (such as the generation of new virtual currency and new virtual items) is triggered by the user's behavior of completing an application event; the first application client or application server can use the built-in The judgment logic of application event completion judges whether the first user completes the application event and obtains the rewarded virtual object, so that when the first user completes the application event, the first application client can obtain the first The completion evidence of the user completing the application event, the completion evidence includes: the completion record of the first user completing the application event, and the virtual object data associated with the application event;

That is, the proof of completion of the first user's completion of the application event may represent evidence that the first user completes the application event and obtains a corresponding virtual object reward; optionally, the completion record of the first user's completion of the application event may include: the first user Complete the behavior record or result record of the application event;

The behavior record of the first user completing the application event may be the corresponding behavior record in the process of the first user completing the application event (that is, the corresponding behavior in the process of completing the application event by the first user indicates that the first user completes the application event. result of the event); such as the behavior record of the first user killing a game monster, etc., the behavior record can be determined by the first application client, or it can be determined by the application server and sent to the first application client;

The result record of the first user completing the application event can be the recorded result status of the first user completing the application event; for example, the answer to a certain question answered by the first user, the result of killing game monsters, etc.; the result record can be obtained by the second user. An application client can determine it by itself, or it can be determined by the application server and delivered to the first application client.

Optionally, the completion record of the first user completing the application event may also include: the description content of the application event; the description content of the application event may be sent by the application server to the first application client; When the client receives the application event, the first application client can obtain the description content from the application server; taking the application event as an application task as an example, the description content of the application event includes task content introduction and the like.

Optionally, FIG. 3 shows a flow chart of an optional method for obtaining completion evidence that the first user completes the application event. This method is applicable to the first application client. Referring to FIG. 3 , the method may include:

Step S200, the first application client acquires the virtual object data associated with the application event when the first user completes the application event.

The virtual object data associated with the application event can be preset, or selected by the user, or randomly determined by the application server, specifically determined according to the virtual object reward rules set by the application event; for example, when the first user completes the application event , the application server may notify the first application client to complete the virtual object data corresponding to the reward of the application event.

Optionally, the first application client may also acquire the description content of the application event;

Optionally, the description content of the application event may be obtained when the first application client receives the application event (for example, the first user receives a game task). Taking the application event as an application task as an example, the first user can use the first application client The terminal refreshes the application task and collects it, so as to obtain the description content of the application event delivered by the application server.

Optionally, for some non-task application events, such as killing monsters, etc., the first application client can obtain the application event information issued by the application server when the first user completes the application event (such as killing a monster). Description content; obviously, for an application event of a task nature, the description content of the application event delivered by the application server may also be obtained when the first application client completes the application event;

Whether the description content of the application event is determined by the first application client or delivered by the application server may depend on actual application design.

Optionally, in an implementation manner, the first application client may send a notification to the server that the first user completes the application event when the first user completes the application event, so that the application server may determine the virtual object data associated with the application event , the application server sends the virtual object data associated with the application event to the first application client;

Optionally, the application server may also simultaneously determine the description content of the application event, and simultaneously send the description content of the application event to the first application client.

Step S210, acquiring the behavior record or result record of the first user completing the application event.

Step S220, according to the virtual object data associated with the application event, and the behavior record or result record, determine the completion evidence of the first user completing the application event.

Optionally, the completion evidence may also include the description content of the application event; that is, according to the description content of the application event, the virtual object data associated with the application event, and the behavior record or result record, the first user can be determined Evidence of completion for completing said apply event.

Subsequently, after the first application client broadcasts the data block to the blockchain network, other application clients in the blockchain network can directly base on the completion record carried in the data block (the completion record can be completed by the first user) The behavior record or result record of the event; or, the description content of the application event, and the behavior record or result record), and the virtual object data associated with the application event, verify the validity of the data block, and prevent the forgery and tampering without the need for the first application client to provide other information to other application clients in the blockchain network to verify the validity of the data block.

Optionally, after the first application client generates the data block, the data block can be broadcast through the automatic broadcast mechanism of the blockchain network. For example, the first application client that generates the data block can first broadcast the data block, and then Through the broadcast of other application clients, it gradually spreads to the entire blockchain network.

Optionally, an application client in the blockchain network can verify whether the data blocks sent by another application client to the blockchain network are valid; According to the application event processing logic, it is judged whether the application event can be completed by using the completion record, and if it is judged that the application event can be completed by using the completion record, then it is judged whether the completion reward of the application event corresponds to the virtual object data , if the completion reward of the application event corresponds to the virtual object data, it is determined that the data block verification is valid; if any judgment result in this process is negative, it can be determined that the data block is invalid;

That is, after an application client in the blockchain network obtains the data block sent by another application client to the blockchain network, it can complete the record of the application event carried in the data block, and according to the application event processing logic, Using the completion record to simulate the completion process of the application event, if the simulation result is that the completion record can complete the application event, and the completion reward of the application event corresponds to the virtual object data carried in the data block, then the data block verification can be determined efficient.

Optionally, FIG. 4 shows a signaling flow of the data processing method provided in the embodiment of the present invention, and the flow may include:

Step S10 , when the first user completes the application event, the first application client sends a notification to the application server that the first user completes the application event.

Step S11, the application server determines the virtual object data associated with the application event, and generates a pair of public key and private key corresponding to the application event.

Step S12, the application server delivers the virtual object data associated with the application event and the private key to the first application client.

Step S13, the first application client acquires the behavior record or result record of the first user completing the application event.

Optionally, the behavior record or result record of the first user completing the application event may be carried synchronously in the content delivered by the application server in step S12, or may be determined by the first application client itself.

Step S14, the first application client signs the behavior record or result record using the private key.

Step S15, the first application client determines the completion evidence of the first user completing the application event according to the virtual object data and the behavior record or result record signed with the private key.

Optionally, the application server may also determine the description content of the application event and deliver it to the first application client, so that the first application client may use the private The behavior record or the result record signed by the key determines the completion evidence of the first user completing the application event.

Step S16, the first application client generates a data block corresponding to the virtual object data according to the completion proof, and carries the behavior record or result signed with the private key in the data block record, and indication information indicating the virtual object data.

Optionally, the data block may also carry the description content of the application event.

Step S17, the first application client adds signature information corresponding to the first user to the data block.

Step S18, the first application client broadcasts the data block added with the signature information to the blockchain network.

Step S19, the second application client receives the data block broadcast to the blockchain network by the first application client.

Optionally, the second application client can be any application client in the blockchain network except the first application client, and the second application client can receive the first application client broadcast to the blockchain network Data blocks; the second application client may correspond to the second user.

Step S20, the second application client parses the received data block, obtains the behavior record or result record signed with the private key, and the indication information indicating the virtual object data.

Optionally, the second application client may also obtain the description content of the application event by parsing the received data block.

Step S21, the second application client requests the public key corresponding to the application event from the application server.

Step S22, the application server sends the public key corresponding to the application event to the second application client.

Step S23, the second application client uses the public key to unlock the behavior record or result record signed with the private key to obtain the behavior record or result record of the first user completing the application event.

Step S24, the second application client simulates the completion process of the application event according to the behavior record or result record, if the simulation result is that the behavior record or result record can complete the application event, and the completion reward of the application event is the same as that of the virtual object Corresponding to the data, it is determined that the data block is valid.

After the second application client unlocks the behavior record or result record signed with the private key, it can obtain the behavior record corresponding to the process of the first user completing the application event (such as the behavior operation required to kill the game monster, etc.), or complete the application The result record of the event (such as the answer to the puzzle, etc.); according to the obtained behavior record or result record, the second application client can simulate whether the behavior record or result record can be completed according to the application event processing logic (such as game logic) Apply the event, and when the simulation result is yes, judge whether the completion reward of the application event corresponds to the virtual object data, so as to realize the verification of the data block.

Optionally, if the behavior record or the result record cannot complete the application event, and/or the completion reward of the application event does not correspond to the virtual object data, it may be determined that the data block is invalid.

Optionally, after the second application client verifies the data block, it can further broadcast the data block in the blockchain network, so that more application clients can verify the data block; if the second If the second application client verifies that the data block is valid, it can add the data block to the blockchain; if the second application client verifies that the data block is invalid, it can discard the data block, and the invalid data block It will not be part of the blockchain, that is, invalid data blocks that have not passed verification will be treated as invalid blocks by the blockchain network, and the virtual objects represented in them have no practical effect in network applications such as games, and cannot pass Transactions are circulated.

Correspondingly, the first application client can also verify the data blocks broadcast by the second application client to the blockchain network, and the data blocks broadcast by the second application client to the blockchain network can carry the second user to complete The completion record of the application event and the indication information indicating the virtual object data associated with the application event completed by the second user, the process of verifying the data block by the first application client can be similar to that shown in Figure 4; the specific optional process can be as follows :

The first application client receives the data block propagated in the blockchain network; the data block carries the private key corresponding to the application event completed by the second user, and the signed behavior record of the second user completing the application event or result record, and indication information indicating the virtual object data associated with the application event completed by the second user;

The first application client parses the received data block, obtains the behavior record or result record signed with the private key, and the indication information indicating the virtual object data;

The first application client requests the public key corresponding to the application event completed by the second user from the application server;

The first application client uses the obtained public key to unlock the behavior record or result record signed with the private key to obtain the behavior record or result record of the second user completing the application event.

The first application client simulates the completion process of the application event according to the obtained behavior record or result record, and verifies the validity of the received data block according to the simulation result;

On the one hand, if the simulation result is that the obtained behavior record or result record can complete the application event, and the completion reward of the application event corresponds to the virtual object data, determine the data block that the second application client broadcasts to the blockchain network efficient;

On the other hand, if the simulation result is that the obtained behavior record or result record cannot complete the application event, and/or, the completion reward of the application event does not correspond to the virtual object data, it can be determined that the second application client broadcasts to The data block of the blockchain network is invalid.

Optionally, the process of the first application client broadcasting the data block to the blockchain network for data block verification can be considered as a broadcast and distributed verification process, that is, the first application client generates a After the data block, it can be broadcast to adjacent application clients (usually through p2p, etc.), and then the application client that receives the data block will verify the data block, and the verification result and the data area The block is further broadcast until it spreads to the entire blockchain network (generally speaking, as long as 5 application clients can pass the verification of the data block, it can be considered that the data block can be recognized by the entire blockchain network ).

Optionally, virtual objects can be divided into virtual currency and virtual items. In the embodiment of the present invention, the generated data block corresponding to virtual currency can be considered as the main data block, and the generated data block corresponding to virtual item The data block can be considered as a side data block; correspondingly, the blockchain can be divided into the main blockchain and the side blockchain, and the corresponding structure can be shown in Figure 5. It is worth noting that the main blockchain and the side blockchain The application clients in the blockchain are basically the same, but the virtual objects represented by the data blocks in the main blockchain and the side blockchain are different;

For the main data block corresponding to the newly generated virtual currency, the embodiment of the present invention does not need to generate an equivalent virtual item; but for the side data block corresponding to the newly generated virtual item, it is necessary to generate an equivalent The main data block corresponding to the virtual currency is locked and locked to ensure that the virtual currency blockchain (that is, the main blockchain) can meet the amount of virtual currency required for the exchange of virtual items.

Optionally, the method of verifying the main data block in the main blockchain network is similar to the principle shown in Figure 4, which can be referred to.

Based on the method shown in Figure 6, taking the game network application as an example, as shown in Figure 7, the game client completes a game task, and the reward of the game task is 100 virtual gold coins, then the game client can determine The virtual object associated with the game task is a virtual gold coin (that is, the virtual object type of the virtual object data associated with the game task is the first type of virtual object, and the virtual gold coin is a form of the first type of virtual object), thus obtaining the game client Evidence of completion of said game mission;

The completion evidence includes: the completion record of the game client completing the game task, and the 100 virtual gold coins associated with the game task; then the game client can generate a master data block corresponding to the 100 virtual gold coins based on the completion evidence, and The data block carries the completion record and the indication information indicating that the main data block corresponds to 100 virtual gold coins; after the game client adds the signature information corresponding to the user of the game client to the main data block, it can be broadcast to the main block In the blockchain network, other game clients can verify the validity of the master data block.

Taking the generation of side data blocks of the second type of virtual object as an example, FIG. 8 shows another flow of the data processing method provided by the embodiment of the present invention. This method can be applied to the first application client. Referring to FIG. 8, The method can include:

Step S400, the first application client determines the virtual object data associated with the application event when the first user completes the application event.

Step S410, if the first application client determines that the virtual object type of the virtual object data is the second type of virtual object, determine the virtual object of the first type of virtual object corresponding to the virtual object data of the second type of virtual object data; and determine the completion proof that the first user completes the application event, and the main data block accompanying generation proof.

Wherein, the completion evidence includes: the first user completes the completion record of the application event, and the virtual object data of the second type of virtual object associated with the application event; the accompanying generation evidence of the main data block includes: Virtual object data of the first type of virtual object.

When the first application client completes an application event, and the type of virtual object data associated with the application event is the second type of virtual object, in addition to generating the virtual object data corresponding to the second type of virtual object associated with the application event In addition to the side data block, it is also necessary to generate the equivalent main data block corresponding to the virtual object data of the first type of virtual object; if the game client completes a game task, and the reward of the game task is a game item, the first application In addition to generating the side data block corresponding to the game item, the client also needs to determine the game currency equivalent to the game item, and at the same time generate the main data block corresponding to the game currency;

Corresponding to the virtual object data of the second type of virtual object, the virtual object data of the first type of virtual object may represent the first type of virtual object equivalent to the second type of virtual object associated with the application event; such as application event The associated reward is a virtual item (a form of the second type of virtual object), and the equivalent currency of the virtual item is 100 virtual gold coins (a form of the first type of virtual object). When the side data block is generated, the main data block corresponding to 100 virtual gold coins needs to be generated along with it.

Step S420, the first application client generates a side data block corresponding to the virtual object data of the second type of virtual object according to the completion evidence, and carries the completion record in the side data block, and Indicating information indicating the virtual object data of the second type of virtual object; and generating a main data block corresponding to the virtual object data of the first type of virtual object according to the accompanying generation evidence of the main data block, the The main data block carries indication information indicating the virtual object data of the first type of virtual object.

Step S430, the first application client adds signature information corresponding to the first user to the side data block.

Step S440, the first application client broadcasts the side data block added with the signature information to the side blockchain network; and locks the main data block to the main blockchain network.

Optionally, when verifying the data block, since the main data block is an equivalent data block generated with the side data block, only the side data block is verified, while the main data block is locked to the main area In the block chain network, the locked main data block is not released until the second type of virtual object represented by the side data block is traded.

Based on the method shown in Figure 8, taking the game network application as an example, as shown in Figure 9, the game client completes a game task, and the reward of the game task is a game item, then the game client can determine The virtual object associated with the game task is a game item (that is, the virtual object type of the virtual object data associated with the game task is the second type of virtual object, and the game item is a form of the second type of virtual object), so that the game client can determine The equivalent game currency of the game item, such as the equivalent game currency is 100 virtual gold coins, then the game client can generate the completion evidence that the first user completes the application event, and the main data block is accompanied by the generation evidence;

The completion evidence is used to represent the completion record of the game client completing the game task, and the game props associated with the game task; the main data block is accompanied by the generated evidence to represent the equivalent of 100 virtual gold coins corresponding to the game props associated with the game task ;

Therefore, the game client can generate a side data block corresponding to the game item according to the completion evidence, and carry the completion record in the side data block, as well as indication information indicating the game item corresponding to the side data block, and then After adding the signature information of the user corresponding to the game client to the data block on the opposite side, it is broadcast to the side blockchain so that other game clients can verify the validity of the data block on the side;

At the same time, the game client can generate evidence according to the main data block, generate a main data block corresponding to 100 virtual gold coins, and carry indication information indicating that the main data block corresponds to 100 virtual gold coins in the main data block; The main data block is locked into the main block chain until the virtual item represented by the side data block is traded, and the main data block is released from the main block chain.

Optionally, the embodiment of the present invention can use the side chain (side block chain) mechanism to automatically lock the main data block on the main chain (main block chain), and unlock it until the main data block is released.

Optionally, using the second type of virtual object and/or the first type of virtual object to synthesize a new second type of virtual object can be regarded as a kind of application event; only the side data corresponding to the new second type of virtual object The generation of the block needs to be accompanied by the invalidation of the original side data block corresponding to the second type virtual object, and/or the invalidation of the original primary data block corresponding to the first type virtual object;

Correspondingly, when the first application client completes the application event, it may also determine that the completion of the application event is accompanied by an invalid data block (may be the main data block corresponding to the first type of virtual object, or may be the data block corresponding to the second type of virtual object). side data block, which may be determined according to the execution requirements of the application event), and invalidate the determined data block.

The above describes the data processing method provided by the embodiment of the present invention in terms of virtual object generation; the following will introduce the data processing method provided by the embodiment of the present invention from the perspective of virtual object transactions; the data processing method described below establishes Based on the generation of virtual objects using blockchain technology described above.

FIG. 10 is another flow chart of the data processing method provided by the embodiment of the present invention. The method can be applied to the first application client. Referring to FIG. 10, the method may include:

Step S500, acquire the transaction request of the first transaction.

Optionally, the transaction request may be a transaction request related to the first user of the first application client; it may also be a transaction request broadcast by other application clients to the blockchain network, that is, when users of other application clients perform the first transaction , other application clients can broadcast the transaction request of the first transaction to the blockchain network, and when the first application client obtains the transaction request, it can generate corresponding data blocks based on the transaction request.

Step S510, generating a data block corresponding to the first transaction according to the transaction request; the data block carries the transaction record of the first transaction and the indication information indicating the virtual object data corresponding to the first transaction.

Different from the existing way of modifying the user data in the database to conduct transactions, the embodiment of the present invention does not modify the virtual currency in the user data according to the transaction request to realize the transaction; but generates the data block corresponding to the transaction , add the data block corresponding to the transaction to the blockchain, that is, when the transaction is realized, the blockchain will not modify the data block that has been generated and added, but will add a new one at the end of the blockchain The data block corresponding to the transaction;

Optionally, the transaction record of the first transaction may record the users involved in the first transaction, the transaction items, currency, etc. of the first transaction, and may record the key data involved in the transaction key of the first transaction.

Step S520, broadcasting the data block to the blockchain network.

Optionally, the first transaction may be a transaction of purchasing a game item. If the game item needs to consume 100 gold coins, the first application client obtains the transaction request and determines that the first user corresponding to the transaction request uses 100 gold coins to purchase the game The transaction record of the props; thus, according to the transaction request, the data block corresponding to the first transaction is generated, and the transaction record is carried in the data block, indicating the consumption of 100 gold coins corresponding to the first transaction, and obtaining the instruction information of the game props;

Optionally, the first transaction may be a transaction request for the first user to sell a game item. For example, if the game item is sold for 100 gold coins, the first application client can obtain the transaction request and determine the first transaction request corresponding to the transaction request. The transaction record of the user selling game props to obtain 100 gold coins; thereby generating the data block corresponding to the first transaction, and carrying the transaction records and instructions in the data block corresponding to the first transaction to obtain 100 gold coins and the instruction of the sold game props information;

Obviously, the first transaction may also be a virtual item-to-virtual item transaction, or a simple transfer of virtual gold coins, a pure transfer of virtual items, etc. The processing principle of these types of transactions is the same as the above description, and the corresponding data is generated according to the transaction request block, and spread to the blockchain network, and other application clients verify the validity of the data block;

Optionally, this embodiment of the present invention can support transactions between users, transactions between users and the game system, and the like.

Optionally, after the data block corresponding to the transaction is broadcast to the blockchain network, the application client in the blockchain network can verify whether the data block is valid. The specific verification principle is similar to that described in Figure 4 above. The transaction records in the data block simulate whether the transaction can be completed, and when the transaction can be completed, determine whether the virtual object data corresponding to the data block is consistent with the transaction and realized;

That is, if the application client in the blockchain network simulates the transaction process based on the transaction records in the data block and judges that the transaction can be completed, and the virtual object data corresponding to the data block matches the transaction, then it is determined that the data block is valid .

Specifically, the first application client may obtain the private key corresponding to the first transaction (the first transaction may correspond to a pair of private key and public key assigned by the application server), and use the private key in the transaction record of the first transaction Signing and carrying in the data block; thus sending the data block carrying the transaction record signed with the private key and the indication information indicating the virtual object data corresponding to the first transaction to the blockchain network;

Therefore, after other application clients receive the data block, they unlock the corresponding public key of the first transaction, use the private key to sign the transaction record, and simulate the completion process of the first transaction according to the transaction record. If the simulation result is The transaction record can complete the first transaction, and the virtual object data corresponding to the data block is consistent with the first transaction, so it is determined that the data block is valid.

Correspondingly, the first application client can verify the data block propagated in the blockchain network; if the first application client receives the data block corresponding to the second transaction propagated in the blockchain network, the first application client The terminal can analyze the received data block, obtain the public key corresponding to the second transaction, and use the obtained public key to unlock the transaction record of the second transaction signed with the private key;

The first application client can simulate the completion process of the second transaction according to the obtained transaction records, so as to verify the validity of the received data blocks according to the simulation results;

If the simulation result shows that the obtained transaction record can complete the second transaction, and the virtual object data corresponding to the data block is consistent with the second transaction, it can be determined that the received data block is valid.

Optionally, if the application client in the blockchain network judges that the transaction cannot be completed after simulating the transaction process according to the transaction records in the data block; and/or, the virtual object data corresponding to the data block does not match the transaction, Then it can be determined that the data block is invalid.

Optionally, the data block shown in Figure 10 can be a main data block or a side data block; it should be noted that if the virtual object data corresponding to the first transaction is, the side data block of the initial transaction corresponds to The second type of virtual object data, because the second type of virtual object data that is traded for the first time, the corresponding master data block of the equivalent first type virtual object is still in a locked state (that is, the equivalent virtual currency, etc. The main data block of the class virtual object is in the locked state), then when the virtual object data corresponding to the first transaction is the second type of virtual object data corresponding to the side data block of the initial transaction, the corresponding virtual object data needs to be in the locked state The main data blocks of the network are released to ensure sufficient currency in the virtual world of the network.

If the virtual object data corresponding to the first transaction has already been traded, the corresponding main data block has been released. At this time, it is no longer necessary to involve the main data block, and two-way transactions can be carried out relatively independently;

Optionally, the equivalence relationship between the second type of virtual object corresponding to the side data block and the first type of virtual object corresponding to the main data block can be set by the operation server according to the actual situation; for example, take the game network application as an example , the operation server can control the issuance of virtual currency and virtual items by adjusting and issuing game tasks, by adjusting the consumption of virtual currency and virtual items when players participate in the game, and the exchange relationship between virtual currency and virtual items (a kind of corresponding relationship) ), to control the ecology of the network virtual world.

In the data processing method provided by the embodiment of the present invention, the processing of virtual objects such as virtual currency and virtual items (virtual props, virtual resources) is managed by the blockchain, and the blockchain of the second type of virtual objects such as virtual items is used as a virtual The side chain of the block chain of the first type of virtual objects such as currency ensures that the conversion relationship between virtual items and virtual currency is certain; the user's behavior in the game (such as completing tasks) can create new data blocks ( main data block, and/or, side data block), if the new data block represents a virtual item (corresponding to the side data block), then an equal amount of virtual currency (corresponding to the main data block) is also created, The two can be freely exchanged, thus ensuring the stability of the currency;

The generation of new data blocks depends on the application behavior of the application client (such as the player's game behavior). Once these application behaviors trigger application events and complete, the data blocks of virtual objects such as virtual currency and virtual items associated with the application events will be Created, and the application behavior that triggers the completion of the application event is determined by the application operator; therefore, although the application operator can still adjust the application content and the exchange relationship between item currencies, it cannot directly modify the user data , realize the generation and transaction of virtual objects such as virtual currency and virtual items, and reduce server resource overhead; at the same time, distributed data block storage improves the security and reliability of user assets.

Based on the data processing method described above, the advantages of the embodiments of the present invention at least include:

By decentralizing the economic ecology of the network virtual world controlled by the operator, the operator cannot directly interfere with the value of the economic system of the network virtual world, but can only indirectly control the economic system of the network virtual world by changing the player's behavior mechanism. The fairness of the network virtual world is guaranteed, and the resource overhead of the server is reduced at the same time;

The data blocks corresponding to the user's virtual currency and virtual items are distributed and stored in the entire blockchain network, and must be modified by most application clients to be recorded, and the data blocks are forged or tampered without permission It can be avoided, ensuring the security of the game, the security and reliability of user assets; and the distributed storage of the blockchain network can effectively avoid the interruption of game services caused by single point of failure, and improve the reliability of network application services such as games sex.
