The manner of generating the data block may include a process for the hash of the previous data block, and the construction of the hash tree. For how to generate the data block, the embodiment of the present invention may apply any technology that can generate the data block; In order to facilitate the subsequent verification of the validity of the generated data block, the generated data block should carry the completion record of the first user completing the application event, and the indication information indicating the virtual object data associated with the application event, so as to be used by other application clients. The end 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 signature information of the first user to the data block.

The signature information corresponding to the first user may uniquely identify the first user, and may be regarded as the identity identifier of the first user, by adding the signature information corresponding to the first user to the generated data block, The generated data block is added to the label of the first user.

Step S130: The first application client broadcasts the data block to which the signature information is added to the blockchain network; the blockchain network accesses multiple application clients.

The application client is used as an access node of the blockchain network, and multiple application clients may form a blockchain network; after the first application client generates the data block, the data block may be added to the blockchain, and the data is The validity of the block needs to be recognized by other application clients in the blockchain network. Therefore, after the first application client generates the data block, it needs to be broadcasted to the blockchain network, and the data block is used by other application clients. Validity is verified.

Optionally, if the behavior record and/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, the data block may be determined to be invalid.

Optionally, after the second application client verifies the data block, the data block may be further broadcasted in the blockchain network, so that more application clients verify the data block; If the application client verifies that the data block is valid, the data block may be added to the blockchain; if the second application client verifies that the data block is invalid, the data block may be discarded, and the invalid data block is discarded. Will not be part of the blockchain, that is, the invalid data block that has not been verified will be treated as invalid block by the blockchain network. The virtual object represented in it does not have practical effect in network applications such as games, and cannot pass. The transaction is in circulation.

Correspondingly, the first application client can also verify that the second application client broadcasts to the data block in the blockchain network, and the data block that the second application client broadcasts to the blockchain network can carry the second user to complete. The process of verifying the data block associated with the application event and the indication information of the virtual object data associated with the application event completed by the second user may be similar to the content shown in FIG. 4; the specific optional process may be :

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

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

The first application client uses the obtained public key to unlock the behavior record and/or the result record signed by the private key, and obtains the behavior record and/or result record of the second user completing the application event.

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

In one aspect, if the simulation result is that the obtained behavior record and/or result record can complete the application event, and the completion reward of the application event corresponds to the virtual object data, determining the data that the second application client broadcasts to the blockchain network The block is valid;

On the other hand, if the simulation result is that the obtained behavior record and/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, the second application client may be determined. The data block broadcast to the blockchain network is invalid.

Optionally, the process that the first application client broadcasts the data block to the blockchain network for data block verification may be regarded as a broadcast and distributed verification process, that is, the first application client generates a certain After the data block, it can be broadcast to the neighboring application client (usually through p2p, etc.), and then the application client receiving the data block will verify the data block, and the verification result and the data area will be verified. The block is further broadcasted until it spreads to the full blockchain network (generally, as long as five application clients can pass the verification of the data block, it can be considered that the data block can be recognized by the full blockchain network. ).

Optionally, the virtual object can be divided into two types: a virtual currency and a virtual item. In the embodiment of the present invention, the generated data block corresponding to the virtual currency can be regarded as a main data block, and the generated virtual item corresponds to the virtual item. The data block can be regarded as a side data block; correspondingly, the block chain can be divided into a main block chain and a side block chain, and the corresponding structure can be as shown in FIG. 5, and it is worth noting that the main block chain and the side are The application clients in the blockchain are basically the same, except that the virtual blocks represented by the data blocks in the main blockchain and the sideblockchain 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 needs to be generated equivalent to the newly generated virtual item. The virtual currency corresponds to the main data block and is locked to ensure that the virtual currency blockchain (ie, the main blockchain) can satisfy the amount of virtual money required for virtual item exchange.

Optionally, the virtual currency can be considered as a form of the first type of virtual object, and the virtual item (such as virtual props, virtual resources, virtual equipment, etc.) can be considered as a form of the second type of virtual object, and the following is for generating the first The main data block of a type of virtual object and the data processing method of the side data block of the second type of virtual object are introduced;

It is worth noting that virtual currency is only an optional form of the first type of virtual object. The virtual item is only an optional form of the second type of virtual object. According to the difference of the network virtual world ecology constructed by the network application, the first type of virtual The specific form of the object and the specific form of the second type of virtual object can be adjusted; it is generally believed that the first type of virtual object has a purchase attribute in the network virtual world ecology constructed by the network application, and the second type of virtual object can be purchased.

FIG. 6 is another flowchart of a data processing method according to an embodiment of the present disclosure. The method may be applied to a first application client. Referring to FIG. 6, the method may include:

Step S300: The first application client determines the virtual object data associated with the application event when the first user completes the application event.

Step S310: The first application client determines that the virtual object type of the virtual object data is a first type of virtual object, and obtains completion evidence that the first user completes the application event; the completion evidence includes: the first user Completing the completion record of the application event and the virtual object data of the first type of virtual object associated with the application event.

Step S320: The first application client generates a main data block corresponding to the virtual object data of the first type of virtual object according to the completion evidence, and carries the completed record in the main data block, and Indicates indication information of virtual object data of the first type of virtual object.

Step S330: The first application client adds signature information corresponding to the first user to the primary data block.

Step S340: The first application client broadcasts the main data block to which the signature information is added to the main blockchain network.

Optionally, the manner of verifying the main data block in the main blockchain network is similar to the principle shown in FIG. 4, and can be referred to.

Based on the method shown in FIG. 6 , taking the game network application as an example, as shown in FIG. 7 , the game client completes a game task, and the reward of the game task is 100 virtual gold coins, and the game client can determine after completing the game task. The virtual object associated with the game task is a virtual gold coin (ie, the virtual object type of the virtual object data associated with the game task is a first type of virtual object, and the virtual gold coin is a form of the first type of virtual object), thereby acquiring the game client. Completion of the completion evidence of the game task;

The completion evidence includes: a completion record of the game client completing the game task, and a 100 virtual gold coin associated with the game task; and the game client may generate a main data block corresponding to 100 virtual gold coins according to 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; the game client adds the main data block to the signature information corresponding to the user of the game client, and then broadcasts to the main block. Chain the network so that other game clients can verify the validity of the main data block.

For example, the process of the data processing method of the embodiment of the present invention is further illustrated. 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: The first application client determines that the virtual object type of the virtual object data is a second type of virtual object, and determines a virtual object of the first type of virtual object corresponding to the virtual object data of the second type of virtual object. Data; and determining that the first user completed the completion of the application event and the evidence accompanying the generation of the primary data block.

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 evidence generated by the primary data block includes: The virtual object data of the first type of virtual object.

When the first application client completes an application event, and the type of the virtual object data of the application event association reward is the second type of virtual object, in addition to generating the virtual object data corresponding to the second type virtual object of the application event association reward. In addition to the side data block, the main data block corresponding to the virtual object data of the first type virtual object is also generated; if the game client completes a game task, and the reward of the game task is a game prop, the first application In addition to generating a side data block corresponding to the game item, the client also needs to determine the game currency equivalent to the game item, and simultaneously generate a 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 a first type of virtual object equivalent to the second type of virtual object associated with the application event; for example, an 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), and the virtual item corresponding to the virtual item is generated. When the side data block is used, it is also required to generate a main data block corresponding to 100 virtual gold coins.

Step S420: The first application client generates a side data block corresponding to the virtual object data of the second type virtual object according to the completion evidence, and carries the completed record in the side data block, and And indicating indication information of 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 generated evidence along the main data block, The main data block carries indication information indicating 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 to which the signature information is added to the side block chain 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 by the side data block, only the side data block is verified, and the main data block is locked to the main area. In the blockchain network, the locked main data block is released until the second type of virtual object represented by the side data block is traded.

Based on the method shown in FIG. 8 , taking the game network application as an example, as shown in FIG. 9 , the game client completes a game task, and the reward of the game task is a game prop, and the game client can determine after completing the game task. The virtual object associated with the game task association reward is a game prop (ie, the virtual object type of the virtual object data associated with the game task is a second type of virtual object, and the game prop 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, if the equivalent game currency is 100 virtual gold coins, the game client may generate the completion evidence of the first user completing the application event, and generate evidence along with the main data block;

The completion evidence is used to indicate that the game client completes the completion record of the game task, and the game task is associated with the rewarded game item; the main data block is accompanied by the generated evidence for representing the equivalent 100 virtual gold coin corresponding to the game item associated with the game task. ;

Therefore, the game client may 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, and indicate the instruction information of the game item corresponding to the side data block, and further After adding the signature information of the user corresponding to the game client to the opposite data block, broadcast to the side blockchain, so that other game clients can verify the validity of the side data block;

At the same time, the game client may generate a main data block corresponding to 100 virtual gold coins according to the generated evidence along the main data block, 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 blockchain until the virtual item represented by the side data block is traded, and the main data block is released from the main blockchain.

Optionally, the embodiment of the present invention may automatically lock the main data block on the main chain (main block chain) by using a side chain (side block chain) mechanism, and then unlock the main data block after being released.

Optionally, the second type of virtual object and/or the first type of virtual object are used to synthesize a new second type of virtual object, which may be considered as one type of application event; but the side data corresponding to the new second type of virtual object The generation of the block needs to be accompanied by the side data block corresponding to the original second type virtual object, and/or the invalidity of the main data block corresponding to the original 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 a primary data block corresponding to the first type of virtual object, or may be a second type of virtual object corresponding to The side data block, depending on the execution requirements of the application event, and invalidate the determined data block.

The data processing method provided by the embodiment of the present invention is introduced in the above, and the data processing method provided by the embodiment of the present invention is introduced from the perspective of the transaction of the virtual object; the data processing method described below is established. Based on the blockchain technique described above, the generation of virtual objects is performed.

FIG. 10 is still another flowchart of a data processing method according to an embodiment of the present disclosure. The method may be applied to a first application client. Referring to FIG. 10, the method may include:

Step S500: Acquire a transaction request of the first transaction.

Optionally, the transaction request may be a transaction request of the first user of the first application client; or may be a transaction request that is broadcasted by the other application client to the blockchain network, that is, when the user of the other application client performs the first transaction. The other application client may broadcast the transaction request of the first transaction to the blockchain network. When the first application client obtains the transaction request, the corresponding data block may be generated based on the transaction request.

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

Different from the existing method of modifying the user data in the database for the transaction, the embodiment of the present invention does not modify the virtual currency in the user data according to the transaction request to implement the transaction; instead, the data block corresponding to the transaction is generated. Adding the data block corresponding to the transaction to the blockchain, that is, when the transaction is implemented, the blockchain does not modify the data block that has been generated and added, but adds 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 user involved in the first transaction, the transaction item of the first transaction, the currency, etc., and may record the key data involved in the transaction of the first transaction.

Step S520: Broadcast the data block to the blockchain network.

Optionally, the first transaction may be a transaction for 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. a transaction record of the item; thereby generating a data block corresponding to the first transaction according to the transaction request, and carrying the transaction record and the consumption of 100 gold coins corresponding to the first transaction in the data block, and obtaining the instruction information of the game item;

Optionally, the first transaction may be a transaction request for the first user to sell the game item. If the price of the game item is 100 gold coins, the first application client may obtain a transaction request and determine the first corresponding to the transaction request. The user sells the game props to obtain a transaction record of 100 gold coins; thereby generating a data block corresponding to the first transaction, and carrying the transaction record and the indication indicating the first transaction corresponding to the 100th gold coin in the data block, and the instruction of the sold game props information;

Obviously, the first transaction may also be a transaction of virtual goods and virtual goods, or simply transfer virtual gold coins, simply transfer virtual items, etc. The processing principle of these types of transactions and the above description are based on transaction requests to generate corresponding data. Blocks are propagated to the blockchain network, and other application clients verify the validity of the data blocks;

Optionally, embodiments of the present invention can support transactions between users, transactions between users and game systems, and the like.

Optionally, after the transaction corresponding data block is broadcasted 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 FIG. 4 above, and may be based on the application client. The transaction record in the data block, whether the simulation transaction can be completed, and when the transaction can be completed, it is judged 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 records the transaction process according to the transaction record 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, 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 pair allocated by the application server), and use the private key for the transaction record of the first transaction. Signing and carrying in the data block; thereby transmitting the transaction record carrying the private key signature and the data block indicating the indication information of the virtual object data corresponding to the first transaction to the blockchain network;

Therefore, after receiving the data block by the other application client, the public key corresponding to the first transaction is used to unlock, and the transaction record signed by the private key is used to 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 matches the first transaction, and the data block is determined to be 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 may parse the received data block, obtain a public key corresponding to the second transaction, and use the obtained public key to unlock the transaction record of the second transaction signed by the private key;

The first application client may simulate the completion process of the second transaction according to the obtained transaction record, thereby verifying the validity of the received data block according to the simulation result;

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

Optionally, if the application client in the blockchain network records the transaction process according to the transaction record in the data block, the transaction may not be completed after the transaction process is simulated; 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 FIG. 10 may be a primary 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 corresponding to the initial transaction corresponds to The second type of virtual object data, because the second type of virtual object data for the first transaction, the corresponding primary data block of the first type of virtual object is still locked (ie, representing the equivalent virtual currency, etc. If the main data block of the virtual object is in the locked state, 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, and the corresponding locked state is required. The main data block is released to ensure sufficient currency in the virtual world of the network.

If the virtual object data corresponding to the first transaction has been traded, the corresponding main data block has been released, and at this time, it is no longer necessary to involve the main data block, and the two-way transaction can be performed 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 may be set by the operation server according to actual conditions; for example, the game network application is taken as an example. The operation server can control the release of virtual currency and virtual items by adjusting and releasing game tasks, by adjusting the virtual currency, the virtual item consumption when the player participates in the game, and the exchange relationship between the virtual currency and the virtual item (a kind of correspondence relationship) ) to control the ecology of the virtual world of the network.

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

The generation of the new data block depends on the application behavior of the application client (such as the player's game behavior). Once the application behavior is triggered, the data block of the virtual object such as the virtual currency and the virtual item of the event association reward is applied. The application behavior that is created and 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 the item currency, it cannot directly modify the user data. It realizes the generation and transaction of virtual objects such as virtual currency and virtual items, which reduces the server resource overhead. At the same time, distributed data block storage improves the security and reliability of user assets.

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

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

The data blocks corresponding to the user's virtual currency and virtual items are distributedly stored in the entire blockchain network, and must be modified by most application clients to be recorded, and the data blocks are forged or falsified privately. It can be avoided to ensure the security of the game, the security and reliability of the user's assets; and the distributed storage of the blockchain network can effectively avoid the interruption of the game service caused by a single point of failure, and improve the reliability of the network application services such as games. Sex.
