[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 As shown, the present invention provides a method for circulating virtual data and assets of blockchain games, including:

[0043] Step 100: Divide the blockchain network into layers to obtain blockchain networks of different layers;

[0044] Step 200: Creating virtual data of various types of games on the blockchain networks of different levels and generating unique identifiers for various types of games based on hash calculations; the various types of games include: card games, role-playing games, and strategic games;

[0045] Specifically, the blockchain network can be divided into different layers, each of which is dedicated to storing virtual data of a specific type of game. For example, one layer can be dedicated to storing virtual data of role-playing games (RPGs), another layer can be used to store virtual data of card games, and so on. This can better organize and manage data of various types of games.

[0046] Step 300: Bind and associate account data of various games according to the unique identifier and generate a pair of private key and public key;

[0047] Step 400: Use the private key and public key to log in to the specified game and sell, buy or modify the virtual data of the game account according to the smart contract.

[0048] Specifically, game developers create virtual data and assets on the blockchain and bind them to specific game characters or accounts to ensure the uniqueness of virtual data and assets; game players trade virtual data and assets through smart contracts on the blockchain. Players can buy and sell in the in-game trading market or through third-party trading platforms. During the transaction, smart contracts will automatically execute the transaction conditions of both parties to ensure the security and transparency of the transaction; players can query their virtual data and assets through transaction records on the blockchain and transfer them to other players or accounts at any time.

[0049] Furthermore, according to the unique identifier, the account data of various games are bound and associated and a pair of private keys and public keys are generated, including:

[0050] Determine the type of the game according to the unique identifier;

[0051] Determine the account data of all players in the current game according to the type of the game, the account data including: game assets and character information;

[0052] Convert the account information into a string to obtain string data;

[0053] A pair of private key and public key is generated according to the string data by using hash calculation.

[0054] Specifically, game developers create a unique identifier for each virtual data and asset on the blockchain, which can be a number, hash value or other form of identifier. This identifier will serve as the unique identifier of the virtual data and assets to ensure their uniqueness in the blockchain network; game developers will bind the created virtual data and assets to specific game characters or accounts. In this way, the virtual data and assets owned by each game character or account will correspond to its unique identifier to ensure the uniqueness of each virtual data and asset; in order to distinguish virtual data and assets in different games, the identification information of the game can be included in the unique identifier. For example, the game name, version number or other game-related information can be added to the identifier to distinguish virtual data and assets in different games; the nodes in the blockchain network will verify the unique identifier of each virtual data and asset to ensure its uniqueness in the entire network. If duplicate identifiers appear, the blockchain network will reject the creation or transaction of the virtual data and assets to ensure uniqueness.

[0055] Furthermore, the converting the account information into a string form to obtain string data includes:

[0056] Performing hash calculation on the string data and the unique identifier to obtain a unique hash value;

[0057] The unique hash value is used as a seed to generate a pair of public and private keys of the player through the elliptic curve digital signature algorithm.

[0058] Specifically, the unique identifier of each type of game is generated according to the steps of game data construction and hash calculation; the generated unique identifier is bound and associated with the player's game account data to ensure the consistency and security of the unique identifier and account data; an elliptic curve encryption algorithm (such as ECDSA) is used to generate a pair of private keys and public keys, the private key is used for signing and identity authentication, and the public key is used for encryption and verification. The private key can be generated by a random number generation algorithm to ensure the randomness and security of the private key. The generated private key is bound to the unique identifier and account data to ensure that the private key can only be used to access and operate specific game account data.

[0059] More specifically, determine the data structure of the game player's account data, including the fields and types of information such as account, assets, and roles; serialize the account data into a string form according to certain rules, and use JSON, XML, and other formats for serialization. For example, organize account, asset, role, and other information in the form of key-value pairs and convert them into strings; splice the serialized account data strings in a certain order to ensure the integrity and consistency of the data. Delimiters or special characters can be added during the splicing process to distinguish different fields or data. Encode the spliced ​​account data string to ensure the readability and security of the data. The string can be encoded using Base64 encoding or other methods; the final string is the converted string form of the game player's account data, which can be bound and associated with the account data as a unique identifier.

[0060] More specifically, the process of generating a player's public and private key pair is as follows:

[0061] Hash the unique identifier and string to generate a unique hash value;

[0062] The hash value is used as a seed to generate the player's public and private key pair through the Elliptic Curve Digital Signature Algorithm (ECDSA).

[0063] The ECDSA algorithm process includes selecting an elliptic curve, generating a base point, selecting a private key, and calculating a public key. The specific steps are as follows:

[0064] Select elliptic curve parameters, such as curve equation, base point, modulus, etc.

[0065] Generate the player's private key: Choose a random number as the private key private_key.

[0066] Calculate the player's public key: Use the elliptic curve algorithm to calculate the public key public_key using the private key and base point.

[0067] The relationship between the public key and the private key: the public key is the result of multiplying the private key by the base point, that is, public_key=private_key*base_point.

[0068] Furthermore, the using of the private key and the public key to log into a designated game includes:

[0069] According to the public key, the game server generates a random first challenge code;

[0070] Signing the random first challenge code using the private key to obtain a first signature result;

[0071] The game server verifies the signature result to obtain a first verification result;

[0072] If the first verification result is passed, the player successfully logs into the specified game.

[0073] Furthermore, the selling, purchasing or changing of virtual data of the game account assets includes:

[0074] Generate a change instruction and send the change instruction to the game server, wherein the change instruction includes: purchasing game assets, selling game assets, and adjusting game data;

[0075] Generate a transaction ID according to the change instruction;

[0076] Sign the transaction ID using the private key to obtain a second signature result;

[0077] The game server randomly generates a second challenge code according to the change instruction;

[0078] The second challenge code is signed using the player's private key to obtain a third signature result;

[0079] Verifying the validity of the third signature result and the second signature result through a smart contract to obtain a second verification result;

[0080] If the second verification result is valid, the transaction is successful.

[0081] Specifically, player A wants to sell a certain amount of virtual assets or change his virtual data, and sends a transaction request to the game server, including the transaction content and target object; the game server generates transaction data based on player A's transaction request, including transaction type (sale, purchase or change), transaction amount, target account and other information; the game server generates a random challenge code and sends the challenge code to player A. Player A signs the challenge code with his own private key to generate a signature result. Player A sends the signature result to the game server. The game server verifies the signature result with the preset public key to ensure the identity and authorization of player A. The game server also signs the transaction data with its own private key to generate another signature result. The game server sends its own signature result together with player A's signature result to the smart contract. The smart contract verifies and confirms the validity of the two signature results to ensure the authorization and consent of both parties to the transaction. After the smart contract confirms that the signatures of both parties are valid, it executes the transaction operation, including asset transfer, data change, etc. The smart contract records the transaction information and results, and updates the account assets and data.

[0082] This embodiment also discloses a circulation system for blockchain game virtual data and assets, including:

[0083] The partitioning module is used to divide the blockchain network into different levels to obtain blockchain networks at different levels;

[0084] A first generation module is used to create virtual data of various games on the blockchain networks of different levels and generate unique identifiers for various games according to hash calculations; the various games include: card games, role-playing games, and strategic games;

[0085] A second generation module is used to bind and associate account data of various types of games and generate a pair of private keys and public keys according to the unique identifier;

[0086] The circulation change module is used to use the private key and the public key to log in to the specified game and sell, buy or change the assets of the game account according to the smart contract.
