[0002] At present, in a blockchain game of a battle type, a user can transfer an NFT (Non-Fungible Token) character in a competition to another user during game playing, but the user receiving the transferred NFT character cannot immediately use the NFT character to participate in the game, resulting in poor user experience. SUMMARY

[0004] In a first aspect, an embodiment of the present application provides a blockchain game control method, comprising: receiving a locking request of a terminal for a virtual character in a blockchain game; feeding back first signature information to the terminal, so that the terminal performs a locking operation on the virtual character based on the first signature information; wherein the locking operation is used to prohibit a transfer operation for the virtual character; and if it is monitored that the locking operation is completed, determining to start the blockchain game.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described below in detail with reference to the embodiments. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present application.

[0017] At present, there are two significant problems in the war-type blockchain game: (1) during the game, the NFT character participating in the game can be transferred to other users; (2) if the attribute value of the NFT character changes due to the game, the user cannot synchronize the change of the attribute value to the blockchain in time, and only the game background can chain the change of the attribute value and pay the relevant fee, which will be not conducive to the benign development of the blockchain game. Based on this, the present application provides a control method, device, server, and storage medium for a blockchain game, which can prohibit the transfer of virtual characters during the game, thereby effectively reducing the situation that the user receiving the virtual character cannot use the virtual character immediately due to the transfer of the virtual character during the game, and further significantly improving the user's game experience.

[0018] To facilitate the understanding of the present embodiment, first, a control method for a blockchain game disclosed by the present embodiment will be described in detail, referring to a flowchart of a control method for a blockchain game shown in FIG. 2. The method mainly includes the following steps S102 to S106: Figure 1

[0019] Step S102, receiving a locking request of a terminal for a virtual character in a blockchain game. The virtual character (i.e., NFT character) can be a token of a blockchain contract applied by the blockchain game. The token is a numerical value in the blockchain contract, and the token includes an owner corresponding to the token and an object represented by the token in the blockchain contract, such as a virtual character being a token of an ERC721 contract or a virtual character being a token of an ERC1155 contract. The locking request is used to request the first signature information required for the locking operation.

[0020] ​In an implementation, when receiving a game starting request of a user, it can be detected whether the virtual character is in a locked state, and if not, a prompt information is sent to the terminal to prompt the user to perform a locking operation on the virtual character, and the user is guided to operate the terminal to make the terminal generate a locking request, so as to receive the locking request sent by the terminal.

[0021] In step S104, the first signature information is fed back to the terminal, so that the terminal performs a locking operation on the virtual character based on the first signature information. The locking operation is used to prohibit a transfer operation on the virtual character, and the transfer operation is to transfer the virtual character from an account of a current user to an account of another user. The first signature information is obtained by signing a token value corresponding to the virtual character (i.e., a token value), a first random value obtained from a blockchain contract, and a value of a lock marker of the virtual character. The value of the lock marker is used to indicate whether the virtual character can be transferred. The first marker value indicates that the virtual character can be transferred, and the second marker value indicates that the virtual character cannot be transferred.

[0022] In an implementation, the token value, the first random value, and the value of the lock marker can be signed based on a private key of the user to obtain the first signature information. The first signature information is sent to the terminal. The user can operate the terminal to initiate a first lock marker modification transaction to modify the value of the lock marker in the blockchain contract from the first marker value to the second marker value, i.e., to set the virtual character to a state in which it cannot be transferred (referred to as a locked state), so as to complete the locking operation.

[0023] In step S106, if it is detected that the locking operation is completed, it is determined that the blockchain game is started. In an implementation, after the value of the lock marker in the blockchain contract is modified to the second marker value, it is determined that the locking operation is completed, and then it is determined that the blockchain game is started.

[0024] The control method of the blockchain game provided by the embodiments of the present application needs to feed back the first signature information to the terminal according to the received locking request before starting the game, so that the terminal performs the locking operation of prohibiting the transfer of the virtual character based on the first signature information, and the blockchain game is started after it is determined that the locking operation is completed. Therefore, the transfer of the virtual character can be prohibited during the game, which effectively reduces the situation that the user receiving the virtual character cannot use the virtual character immediately due to the transfer of the virtual character during the game process, and thus the game experience of the user is significantly improved.

[0025] In an embodiment, an airlock mark (also referred to as an airlock tag) corresponding to the virtual role is added to a blockchain contract applied by the blockchain game. For example, an airlock tag is added to a token of an ERC721 contract. If the value of the airlock tag is a second tag value (such as true or 1), a transfer operation on the token is prohibited. If the value of the airlock tag is a first tag value (such as false or 0), a transfer operation on the token is allowed.

[0026] On this basis, an embodiment of the present application provides an embodiment of generating first signature information. A first random value corresponding to the virtual role is read from a blockchain contract. A token value corresponding to the virtual role, the first random value, and a first tag value of a lock tag are signed based on a private key carried in a lock request to obtain the first signature information. The first tag value is used to allow a transfer operation on the virtual role. In an embodiment, when receiving the lock request, a game backend (also referred to as a server) reads a current nonce value of an airlock tag corresponding to a token in the blockchain contract. The current nonce value is the first random value. Then, a signature is generated using the private key. The signed content includes a token value (also referred to as the token value), a current value of the airlock tag corresponding to the token (the first tag value), and a current nonce value of the airlock tag corresponding to the token (the first random value). Thus, the first signature information is obtained.

[0027] After the first signature information is generated, the first signature information can be sent to the terminal to enable the terminal to perform a locking operation on the virtual character based on the first signature information. Specifically, the terminal can initiate a first lock marker modification transaction based on the first signature information to perform a locking operation on the virtual character using the first lock marker modification transaction. The first lock marker modification transaction is used to verify the first signature information, modify the first random number value, and modify the lock marker from the first marker value to the second marker value. The second marker value is used to prohibit a transfer operation on the virtual character. In a specific implementation, the player can operate the terminal to access the blockchain contract by calling a wallet signature transaction (as the first lock marker modification transaction) to modify the value of the airlock marker corresponding to the token in the blockchain. The blockchain contract verifies the token value, the value of the airlock marker, and the current nonce value to verify whether the first signature information is legal. When the first signature information is legal, the value of the airlock marker corresponding to the token is modified from false to true, and the current nonce value of the airlock marker corresponding to the token is incremented by 1 to prevent the current nonce value from being used multiple times, thereby preventing a replay attack.

[0028] When the game backend monitors that the value of the airlock marker corresponding to the token is set to the second marker value (such as true), the blockchain game can be started. Further, in the game process, the attribute value change information of the virtual character can also be listened to, and when the blockchain game ends, the attribute value change information is uploaded to the blockchain to which the blockchain game belongs. Exemplarily, the attribute value can be that the virtual character obtains a virtual equipment, the honor value of the virtual character increases by 100, the revival times of the virtual character decrease by 1, and the like. The actual situation of the blockchain game can be set, and the embodiments of the present application do not limit this. In the embodiments of the present application, the attribute value change information of the token is recorded in the game backend, and after the game ends, the attribute value change information is synchronized to the blockchain, which can to some extent avoid the loss of the game party due to the attribute value change information not being uploaded in time.

[0029] In an embodiment, if the user has a transaction or other needs, a locking operation needs to be performed on the virtual character to allow a transfer operation on the virtual character. In an embodiment, steps a to d can be referred to as follows:

[0030] Step a, in the case where the blockchain game ends, receiving a locking request of the terminal for the virtual character. In an embodiment, the user can apply to the game backend to unlock the virtual character by operating the terminal. Exemplarily, a locking control is provided through the graphical user interface of the terminal, and the game backend can receive the locking request sent by the terminal in response to the triggering operation of the locking control.

[0031] Step b, reading the second random value corresponding to the virtual role from the blockchain contract. In an implementation, the game backend will read the current nonce value of the token corresponding airlock flag in the blockchain contract when receiving the unlocking request, which is the second random value mentioned above. It should be noted that the blockchain contract has modified the current nonce value in the blockchain contract (such as +1) after verifying the legality of the first signature information, therefore, the current nonce value read from the blockchain contract in the unlocking process is different from the current nonce value read in the previous locking process.

[0032] Step c, based on the private key carried by the unlocking request, signing the token value corresponding to the virtual role, the second random value, the second flag value of the lock flag, and the attribute value change information to obtain the second signature information. In an implementation, the private key is then used to generate a signature, and the signed content includes the token value, the current value of the token corresponding airlock flag (which is the second flag value), the current nonce value of the token corresponding airlock flag (which is the second random value), and the attribute value change information, which can obtain the second signature information.

[0033] Step d, feeding back the second signature information based on the attribute value change information to the terminal, so that the terminal executes the unlocking operation on the virtual role in the blockchain game based on the second signature information. Wherein, the unlocking operation is used to allow the transfer operation for the virtual role.

[0034] In an implementation, by feeding back the second signature information to the terminal, the terminal can initiate a second lock flag modification transaction based on the second signature information to execute the unlocking operation on the virtual role using the second lock flag modification transaction. Wherein, the second lock flag modification transaction is used to verify the second signature information, modify the second random value, modify the lock flag from the second flag value to the first flag value, and modify the attribute value of the virtual role based on the attribute value change information. In specific implementation, the player can operate the terminal to access the blockchain contract again by calling the wallet signature transaction (which is the first lock flag modification transaction) to modify the value of the token corresponding airlock flag in the blockchain, and the blockchain contract verifies the token value, the value of the airlock flag, the current nonce value, and the attribute value change information to verify the legality of the second signature information, and modifies the value of the token corresponding airlock flag from true to false when the second signature information is legal, and increments the current nonce value of the token corresponding airlock flag by 1, and modifies the attribute value of the token according to the attribute value change information.

[0035] In an implementation, based on the attribute value change information and the unlocking operation, a payment instruction corresponding to the virtual role can be generated and sent to the terminal to enable the terminal to perform a payment operation. For example, when it is detected that the unlocking operation is completed, the cost information generated by the blockchain when changing the attribute value can be obtained, and a corresponding payment instruction can be generated based on the cost information and sent to the terminal to display a payment interface through the graphical user interface of the terminal, and the user can complete the payment on the payment interface. According to the embodiment of the application, by binding the token attribute synchronization and the token unlocking operation together, the gas cost generated when the attribute value is synchronized can be distributed to the corresponding user for payment, thereby saving the project expenditure of the game party and promoting the benign development of the blockchain game.

[0036] In an implementation, if it is detected that the unlocking operation is completed, a transfer request for the virtual role can be received to transfer the virtual role to a target account corresponding to an account identifier based on the account identifier carried in the transfer request. In actual application, since the virtual role is in a state allowing the transfer operation (i.e., the unlocked state), when the transfer request is received, the virtual role can be transferred from the current account to the target account, thereby realizing the sale of the virtual role.

[0037] To facilitate the understanding of the above embodiments, the embodiment of the application further provides an application example of a control method of a blockchain game, which is shown in a time sequence diagram of a control method of a blockchain game. Figure 2

[0038] (1) In the locking phase:

[0039] Step 1: The user terminal (i.e., the terminal) applies to the game backend for the first signature information of the airlock marker. In actual application, if the user terminal plans to start the game, since the token needs to be locked, the user terminal needs to apply to the game backend for the first signature information of the airlock marker.

[0040] Step 2: The game backend reads the current nonce value of the airlock marker corresponding to the token in the blockchain contract (such as an ERC721 contract or an ERC1155 contract).

[0041] Step 3: The blockchain contract returns the current nonce value.

[0042] Step 4: The game backend generates the first signature information using the private key. The signed content includes the token value, the current value of the airlock marker corresponding to the token, and the current nonce value of the airlock marker corresponding to the token.

[0043] ​Step 5, the game backend returns the first signature information to the user end.

[0044] Step 6, the user end calls the wallet signature transaction. In practical applications, by calling the wallet signature transaction, the blockchain contract can be accessed, and then the value of the airlock mark corresponding to the token in the blockchain contract can be modified.

[0045] Step 7, the blockchain contract verifies the first signature information, modifies the value of the airlock mark corresponding to the token to true, and adds 1 to the current nonce value of the airlock mark corresponding to the token.

[0046] Step 8, the blockchain contract calls the contract to return.

[0047] (2) In the unlocking phase:

[0048] Step 1, the user end applies to the game backend for the second signature information of the airlock mark. In practical applications, if the user end plans to unlock the token for other purposes (such as selling), it needs to apply to the game backend for the second signature information of the airlock mark at this time.

[0049] Step 2, the game backend reads the current nonce value of the airlock mark corresponding to the token in the blockchain contract.

[0050] Step 3, the blockchain contract returns the current nonce value.

[0051] Step 4, the game backend generates the second signature information using the private key. The signed content includes the token value, the current value of the airlock mark corresponding to the token, the current nonce value of the airlock mark corresponding to the token, and the attribute value change information of the token.

[0052] Step 5, the game backend returns the second signature information and the attribute value change information to the user end.

[0053] Step 6, the user end calls the wallet signature transaction. In practical applications, by calling the wallet signature transaction, the blockchain contract can be accessed, and then the value of the airlock mark corresponding to the token in the blockchain contract can be modified.

[0054] Step 7, the blockchain contract verifies the second signature information, modifies the value of the airlock mark corresponding to the token to false, adds 1 to the current nonce value of the airlock mark corresponding to the token, and modifies the attribute value change information of the token.

[0055] Step 8, the blockchain contract calls the contract to return.

[0056] In summary, the embodiment of the present application can prevent the user from transferring the virtual character being used in the game process, and can synchronize the attribute change of the virtual character in the game to the chain in a manner beneficial to all, thereby promoting the benign development of the chain game project.
