[0010] According to the game room where the client is located, the generated game credential is broadcasted to other game players in the game room.

[0011] According to one embodiment of the present application, generating the game credentials of the client in the game game based on the player identification of the game player corresponding to the client and the start time of the game game includes: performing a hash operation on the player identification of the game player corresponding to the client to obtain a first hash value; using the first hash value as a key, encrypting the start time of the game game, and using the encryption result as the game credentials of the client in the game game.

[0012] According to one embodiment of the present application, the initial card order in the game round is determined by the contract algorithm according to the game credentials of the game player corresponding to the client in the game round and the game credentials of the other game players, including: determining the target parameter according to the game credentials of the game player corresponding to the client and the game credentials of the other game players; performing a hash operation on the target parameter to obtain a second hash value; taking the second hash value as the dividend and the sequence number of the card as the divisor, performing a modulo operation according to the second hash value and the sequence number of the card to obtain the parameter value corresponding to each sequence number; determining the card corresponding to the sequence number according to the card information mapped by the parameter value.

[0013] According to one embodiment of the present application, determining the target parameter based on the game credentials of the game player corresponding to the client and the game credentials of the other game players includes: performing an XOR operation on the game credentials of each game player in the game round, and using the XOR result as the target parameter.

[0014] According to one embodiment of the present application, determining the target parameters based on the game credentials of the game player corresponding to the client and the game credentials of the other game players includes: obtaining the hash value of the latest generated block in the blockchain; performing an XOR operation on the game credentials of each game player in the game game and the hash value of the latest generated block, and using the XOR result as the target parameter.

[0015] According to one embodiment of the present application, the method further includes: after the game round ends, the game result of the game round, the game credentials of each game player in the game round, and the data indicating the initial card order are associated and stored in the blockchain.

[0041] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0042] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0043] See also Figure 1 , Figure 1 It is an optional structural diagram of the blockchain system 100 provided in an embodiment of the present invention. The blockchain system 100 includes a distributed system formed by connecting multiple nodes 110 in the form of network communication, wherein the node 110 can be any form of computing device (such as a server, user terminals such as smart phones, and other electronic devices) connected to the network.

[0044] The nodes 110 form a peer-to-peer (P2P) network. The P2P protocol is an application layer protocol running on the Transmission Control Protocol (TCP). In this system, any machine such as a server or a terminal can join and become a node. The node includes a hardware layer, an intermediate layer, an operating system layer, and an application layer. Each node 110 includes the same blockchain.

[0045] See also Figure 1The functions of each node in the blockchain system 100 shown include:

[0046] 1) Routing: a basic function of a node, used to support communication between nodes.

[0047] In addition to the routing function, the node can also have the following functions:

[0048] 2) Applications, which are deployed in the blockchain to implement specific businesses according to actual business needs, record data related to the implementation of functions to form record data, carry digital signatures in the record data to indicate the source of the task data, and send the record data to other nodes in the blockchain system. The record data, such as game player's game credentials, game results, etc., are used by other nodes to add the record data to the block when the source and integrity of the record data are successfully verified.

[0049] The services implemented by the application may include:

[0050] 1) Contract algorithm, a computerized protocol that can execute the terms of a contract, is implemented by code deployed on a node for execution when certain conditions are met. The smart contract can also be a contract that processes received information, such as generating data indicating the initial card order based on the game credentials of each game player, which is not specifically limited here.

[0051] 2) Blockchain, including a series of blocks that are connected to each other in the order of their generation. Once a new block is added to the blockchain, it will not be removed. The block records the data submitted by the nodes in the blockchain system. The record data can be the game credentials of game players, the game results in the game, etc.

[0052] See also Figure 2 , Figure 2 This is an optional schematic diagram of a blockchain provided by an embodiment of the present invention. Each block includes data, a hash value of the current block (the hash value of the current block), and a hash value of the previous block. Each block is connected by a hash value to form a blockchain. In addition, the block may also include information such as a timestamp when the block was generated. Blockchain is essentially a decentralized database, a string of data blocks generated by cryptographic methods. Each data block contains relevant information for verifying the validity of its information (anti-counterfeiting) and generating the next block.

[0053] Figure 3 FIG. 1 is a schematic diagram of an implementation environment of the present disclosure according to an embodiment. Figure 3As shown, the environment of this embodiment includes a game platform 310 and a blockchain system 100. The game platform 310 can be a chess game platform or a card game platform. The game platform 310 includes a server 310 that provides services for the game client and a terminal 311 where the game client is located.

[0054] The terminal 311 may be a smart phone, tablet computer, laptop computer, desktop computer, or the like that can communicate with the server and run the client program in the game platform.

[0055] The terminal 311 where the game client is located implements the method of the present disclosure by interacting with the server 312 in the game platform and the node 110 in the blockchain system 100. It is worth mentioning that the service provided by the server in the game platform of the present disclosure to the game client does not include the service of determining the initial card order for the client.

[0056] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0057] Figure 4 1 is a flow chart of a data processing method in a chess and card game according to an embodiment, and the method is applied to a client in the chess and card game. Figure 4 As shown, the data processing method in the chess and card game at least includes steps 410 to 450, which are described in detail as follows:

[0058] Step 410, receiving game credentials broadcasted by other game players in the game session, where the game credentials are related to the player ID of the corresponding game player and the start time of the game session.

[0059] Chess and card games are a general term for board games and card games. Card games include poker, Landlord, Mahjong, etc., and chess games include Chinese chess, military chess, etc.

[0060] The client used to execute the method disclosed herein is a terminal corresponding to a game client of a chess and card game, for example Figure 3 The terminal 311 in. For example, if the chess and card game is a Landlord game, then the client is a client of the Landlord game application.

[0061] In chess and card games, before players officially play against each other in each game, they need to determine the initial card order in the game. The initial card order indicates the order of each card involved in the game.

[0062] Simply put, in card games, the process of determining the initial card order in the game is the process of shuffling. Then, based on the determined initial card order, cards are dealt to each player, and the corresponding players can know the cards (or chess pieces) they hold.

[0063] The game round of the present disclosure refers to a game round in a chess and card game. Each game round involves at least two game players, so there are at least two game players in the game round. In chess and card games, players interact with other players' clients through a client. It can be understood that each game player interacts with other players' game clients or servers through his own client.

[0064] The player identification of a game player is used to identify the game player. The player identification may be the game player's account number in the game application, the ID number of the corresponding registered player, a random number generated for the game player, or the device identification number of the computer device where the client is located, such as the SN code (Serial Number) and the IMEI number (International Mobile Equipment Identity). Of course, the above examples of player identification are only illustrative examples, and other identification information that can identify game players may also be used, which is not specifically limited here.

[0065] The start time of a game session is used to indicate the time when the game session starts. It is understandable that the start time of a game session is different in multiple game sessions participated by the same game player.

[0066] Game credentials refer to credential data used to indicate that a game player participates in a game round. In the solution disclosed herein, the game credentials of a game player are related to the player ID of the game player and the start time of the game round in which the game player is located. That is, changes in the player ID and / or changes in the start time will result in changes in the game credentials. Therefore, in this solution, the game credentials of the game player change correspondingly with changes in the game round in which the game player is located, thereby achieving real-time generation of the game credentials of the game player according to the game round in which the game player joins.

[0067] Each game player can participate in the next game round after a game round ends. Therefore, the game round that the game player joins can be accurately indicated by the game credentials related to the player's player identification and the start time of the game round.

[0068] It is understandable that, before step 410, the client of each game player participating in the game session generates its own game credentials according to the player ID of the corresponding game player and the start time of the game session, and broadcasts the generated game credentials to other game players in the game session, so that any game player in the game session can obtain the game credentials of other game players in the game session. Through this process, the game players in the game session can exchange game credentials.

[0069] Step 430, calling the contract algorithm in the blockchain.

[0070] Step 450, through the contract algorithm, determine the initial card order in the game game according to the game credentials of the game player corresponding to the client in the game game and the game credentials of the other game players.

[0071] For card games, the initial card order refers to the order of the cards before they are dealt, and the process of determining the initial card order implemented by steps 410-450 is equivalent to the process of shuffling. For chess games, the initial card order refers to the order of the chess pieces before they are distributed to the players.

[0072] The contract algorithm is an algorithm configured for the order of the cards in the game. In a specific embodiment, a blockchain interface is integrated in the client, so that the client calls the contract algorithm from the blockchain of any node in the blockchain system through its own integrated blockchain interface.

[0073] It is understandable that the input parameters of the contract algorithm at least include the game credentials of each game player in the game. Therefore, on this basis, through the contract algorithm, the initial card order in the game is determined according to the game credentials of each game player in the game.

[0074] Furthermore, since the number of chess pieces or cards in different types of chess and card games is different, the initial card order is related to the number of chess pieces (or the number of cards). Therefore, the input parameters of the contract algorithm may also include the number of chess pieces (or the number of cards). In the scheme disclosed herein, after obtaining the game credentials of other game players in the game and its own game credentials, the client corresponding to the game player participating in the game game determines the initial card order in the game game by calling the contract algorithm in the blockchain according to the game credentials of each game player in the game game. On the one hand, the contract algorithm is stored in the cross-chain to ensure the immutability of the contract algorithm. On the other hand, the game credentials of the game player are related to the player identification of the game player and the start time of the game game, which is equivalent to the game credentials being generated in real time. Based on the above two reasons, the security of the process of determining the initial card order in the game game is guaranteed, and the process of determining the initial card order can be effectively prevented from being maliciously interfered with. If this method is applied to card games, the problem of malicious interference in the shuffling process in the prior art can be solved.

[0075] Furthermore, in the disclosed solution, the initial card order is determined by any client in the game round, thereby achieving decentralization to determine the initial card order. Since it does not rely on a centralized server to determine the initial card order in the game round according to set rules, it can avoid the problem of malicious tampering of the shuffling process in the prior art, and further avoid the occurrence of game cheating by tampering with the rules in the centralized server to change the initial card order in the game round.

[0076] In one embodiment, if Figure 5 As shown, before step 410, the method further includes:

[0077] Step 510, after starting the game round, obtain the start time of the game round.

[0078] Step 530, generating a game credential for the client in the game according to the player ID of the game player corresponding to the client and the start time of the game.

[0079] After generating the game credential of the current game round of the game player according to the player ID of the game player corresponding to the client and the start time of the game round, the correlation between the game credential and the player ID and the start time of the game round can be ensured.

[0080] It is understandable that other game players in the game round also generate their own game credentials in the game round through the above steps 510-530, so that the client executing the method disclosed in the present invention can correspondingly receive the game credentials broadcasted by other game players.

[0081] If the game player enters the next game, the start time of the game will change. Therefore, the game credentials need to be generated again according to the game player's player ID and the start time of the new game, and stored in the blockchain accordingly, so that the game player's game credentials change with the changes in the game game the game player joins.

[0082] In one embodiment, if Figure 6 As shown, step 530 includes:

[0083] Step 610: Perform a hash operation on the player identifier of the game player corresponding to the client to obtain a first hash value.

[0084] Step 630, using the first hash value as a key, encrypting the start time of the game round, and using the encryption result as the game credential in the game round.

[0085] The hash operation in step 610 is performed by a hash function, such as MD5, MD4, SHA256, etc. The first hash value obtained by performing the hash operation on the player identification is used as the unique identification code of the game player.

[0086] The generation of game credentials is achieved through the above process.

[0087] In another embodiment, a node in the blockchain system generates an encryption key for the game player, so that the game player encrypts the player identification and the start time of the game round through the key generated by the node, and uses the encryption result as the game credential of the corresponding game player in this game round.

[0088] In another embodiment, if Figure 7 As shown, after step 530, the method further includes:

[0089] Step 550, broadcast the generated game credentials to other game players in the game room according to the game room where the client is located. The game room is a virtual room for playing games provided by the server corresponding to the chess and card game. After receiving game requests from multiple game players, the server allocates an idle game room to the multiple game players after the number of game players meets the set requirements. After joining a game room, the game player can play one or more games in the game room.

[0090] Since the game players can start the game round only after entering the game room, the game players in the game round can be determined according to the game room where the client is located.

[0091] It is worth mentioning that in the solution disclosed herein, the server corresponding to the game application does not provide the client with a service for determining the initial card order. Instead, the client of the game application determines the initial card order based on the game credentials of each game player in the blockchain and the contract algorithm.

[0092] The game players participating in the game are determined according to the game room, so that the game players in the game room are used as broadcast objects to broadcast the generated game credentials. Correspondingly, each game player in the game room can receive the game credentials broadcasted by other game players, thus realizing the exchange of game credentials among the game players in the game.

[0093] Since the game credentials of a game player are related to the player identification and the start time of the game round, if a game player participates in multiple game rounds, the game credentials in each game round are different.

[0094] In one embodiment, if Figure 8As shown, step 450 includes:

[0095] Step 810: Determine target parameters based on the game credentials of the game player corresponding to the client and the game credentials of other game players. In the solution disclosed in the present invention, the determination of the target parameters is related to the game credentials of each game player in the game.

[0096] After obtaining the game credentials of each game player in the current game session, numerical or logical operations may be performed on the game credentials of each game player to determine the target parameter.

[0097] In one embodiment, an XOR operation is performed on the game credentials of each game player in the game round, and the XOR result is used as the target parameter.

[0098] For example, if the game players participating in the game round include A, B, C, and D, where the game credential of game player A in the game round is T1, the game credential of B in the game round is T2, the game credential of C in the game round is T3, and the game credential of D in the game round is T4, then the target parameter = T1 XOR T2 XOR T3 XOR T4, where XOR represents an exclusive OR operation.

[0099] Step 830: Perform a hash operation on the target parameter to obtain a second hash value.

[0100] Step 850, using the second Hash value as the dividend and the serial number of the card as the divisor, performing a modulo operation based on the second Hash value and the serial number of the card to obtain parameter values ​​corresponding to each serial number.

[0101] In chess and card games, multiple chess pieces or cards are involved, and the initial card serial number is used to indicate the order of the multiple chess pieces or cards.

[0102] For example, in the Landlord game, there are 54 cards in total, and the initial card sequence is used to indicate the sequence of the 54 cards. Therefore, the initial card sequence includes 54 sequence numbers, namely 1-54.

[0103] For another example, in a simplified version of Mahjong game, a total of 136 cards are included, and the initial card sequence is used to indicate the sequence of the 136 cards. Correspondingly, the initial card sequence includes 136 sequence numbers, namely 1-136.

[0104] Therefore, in step 850, the serial number is taken according to the number of cards or chess pieces involved in the game, and each serial number is used as a divisor, and the divisor is modulo operated with the dividend, and the result of the modulo operation is used as the parameter value of the corresponding serial number.

[0105] Specifically, assuming the target parameter is Q and the parameter value is K, then K = Q mod N, where N = 1, 2, 3, 4, ... n, and n is the total number of cards or pieces in the game. Calculate each value corresponding to N according to this formula to get the parameter value of the corresponding sequence number.

[0106] Step 870, determine the card face corresponding to the sequence number according to the card face information mapped by the parameter value.

[0107] In order to determine the initial card order, a mapping relationship between parameter values ​​and card information is constructed, so that, based on the mapping relationship, the card information mapped to the parameter value corresponding to each sequence number is determined, and the card information is used to indicate the corresponding card. Correspondingly, the card of the sequence number is determined based on the card information.

[0108] Continuing the above example, the game is a simplified version of Mahjong, then n = 136. Based on K = Q mod N:

[0109] If N=1, K=4 is calculated, wherein the card face information mapped by parameter value 4 indicates that the card face is 10,000, and the card face of the card with sequence number 1 is 10,000.

[0110] If N=3, K=6 is calculated, wherein the card face information mapped by the parameter value 6 indicates that the card face is three of a kind, and the card face of the card with the sequence number 3 is three of a kind.

[0111] In a specific embodiment, in order to realize the mapping between parameter value and card information, the card information is stored in an array, and the parameter value is used to indicate the address of the element in the array. Therefore, after determining the parameter value, the element in the array is determined according to the address corresponding to the parameter value, so that the card information stored in the element is the card information mapped by the parameter value. In other words, the mapping process of parameter value→address→element in the array→card information is realized.

[0112] In another embodiment, if Fig. 9 As shown, step 810 includes:

[0113] Step 910, obtain the hash value of the latest generated block in the blockchain.

[0114] Step 930, perform an XOR operation on the game credentials of each game player in the game and the hash value of the latest generated block, and use the XOR result as the target parameter.

[0115] As described above, each block in the blockchain not only stores the hash value of the previous block it is linked to, but also stores the hash value of the current block. Therefore, the hash value of the latest generated block can be obtained from the blockchain.

[0116] For example, if the game players participating in the game include A, B, C, and D, where the game credential of game player A in the game is T1, the game credential of B in the game is T2, the game credential of C in the game is T3, and the game credential of D in the game is T4, and the hash value of the latest generated block in the blockchain is P, then the target parameter = T1 XOR T2XOR T3 XOR T4 XOR P, where XOR represents an exclusive OR operation. In this embodiment, an exclusive OR operation is performed by adding the hash value of the latest generated block, and the hash value of the latest generated block and the game data of each game player in the game are used as influencing factors of the target parameter, which increases the influencing factors for determining the target parameter and further ensures the uniqueness of the target parameter.

[0117] In other embodiments, the random number may be XORed with the game credentials of each game player to determine the target parameter, which is not specifically limited here.

[0118] In one embodiment, the method further comprises:

[0119] After the game is over, the game results of the game, the game credentials of each player in the game, and the data indicating the initial card order are associated and stored in the blockchain.

[0120] It is understood that the game result of a game session at least indicates the winning game players and the losing game players in the game session.

[0121] In a game, when the victory condition is met, the game ends. At this time, the game result of the game, the game credentials of each player in the game, and the data indicating the initial card order are reported to the node in the blockchain system, and the node stores these three data in association in the blockchain.
