Description

Method, device and system for providing NFT transaction brokerage platform services based on attribute values within the game environment {METHOD, DEVICE AND SYSTEM FOR PROVIDING NFT TRANSACTION MEDIATION PLATFORM SERVICE BASED ON ATTRIBUTE VALUE IN GAME ENVIRONMENT}

The examples below mediate data (characters, items, etc.) within the game environment to be traded by converting them into NFTs, but information about the in-game data (attribute values within the game environment) as well as the scarcity of the NFT as an NFT is also provided on the platform. It relates to a method, device, and system for providing an NFT transaction brokerage platform service based on attribute values within the game environment that adds fun to the game and improves the value of NFT by providing it.

Recently, cases of research, development and commercialization of blockchain-related technologies have been rapidly increasing.

In particular, the concept of 'ownership' of digital data is being established by making it possible to prove ownership of data with a certain artistic value, such as images, by making it a unique non-fungible token rather than a general fungible token.

Accordingly, attempts to prove ownership of goods in the game by incorporating non-fungible tokens (NFTs) into online games are increasing.

In general, the price difference between each NFT is generated by evaluating the scarcity of the NFT based on the probability of a certain part appearing in a randomly generated image (character, item, etc.).

However, the scarcity value based on the NFT creation probability is not suitable for decentralization, which is the purpose of blockchain, in that it is fixed to the value specified by the creator (manager) that creates the NFT, so it is not suitable for transactions or demand between users within the game. Accordingly, an NFT brokerage platform that can evaluate scarcity/value differently is needed.

According to one embodiment, in a method of providing an NFT transaction brokerage platform service based on attribute values within a game environment performed by a device, creation and update processing are performed from a predetermined game database 2. Monitoring step (S100); A step of generating a first non-fungible token (NFT) corresponding to the first content based on the generation process of the first content occurring in the game database 2 (S200); In the game database 2, recording a first hash value of the first non-fungible token into the first content (S300); Registering the first non-fungible token, including a first attribute value of the first content, in a market (S400); Indicating the first attribute value in sales information of the first non-fungible token (S500); Modifying the first attribute value by transacting the first non-fungible token based on the occurrence of update processing of the first content in the game database 2 (S600); Receiving a purchase request message for the first non-fungible token (S700); Receiving a sales acceptance message corresponding to the purchase request message (S800); and transacting the first non-fungible token based on the sale acceptance message (S900), wherein the first attribute value is: a second attribute that is game environment data recorded in the game database 2 value(P2); and a third attribute value (P3), which is a scarcity index of the first non-fungible token calculated based on the second attribute value (P2) of the third non-fungible tokens registered in the market. Provides a method of providing value-based NFT transaction brokerage platform services.

General web games or online games are linked to the game database 2, and in-game goods or character information are stored in the game database 2 and operate based on this.

The game database 2 is equipped with basic CRUD (Create, Read, Update, Delete) functions, and can perform predetermined processing as a trigger when the CRUD function (method, script, etc.) is processed.

In one embodiment of the present invention, whether creation and update processing occurs is monitored (detection of creation and update triggers), and when a character or item in the game is created, a corresponding NFT is created.

In the step (S200) of generating a first non-fungible token (NFT) corresponding to the first content, based on the occurrence of the creation process of the first content in the game database 2; Tokens are created and minted based on blockchain and NFT technology, and detailed descriptions of these known technologies are omitted.

The first content may include a category pre-designated by an administrator or the like. For example, in the case of consumable items among in-game goods, the value is low and there is no scarcity, so they are not converted into NFTs, but the first non-fungible token is generated only for items, characters, and equipment items that can be installed in a certain metaverse space. It can be limited.

In the game database 2, recording the first hash value of the first non-fungible token in the first content (S300), the generated first non-fungible token and the in-game goods/ In order to link the first content such as a character, a 'hash value' label is added to the information of the first content of the game database 2, and the hash value of the generated first non-fungible token is updated to update the game database ( Register in 2).

Based on this, in-game users can check the hash value of the NFT corresponding to the first content, such as any character or item.

In the step (S400) of registering the first non-fungible token in the market, including the first attribute value of the first content, the first attribute value (second attribute value (P2) and third attribute value (P3) ) Register NFTs on the market, including ).

According to the step (S500) of indicating the first attribute value in the sales information of the first non-fungible token, as shown in FIG. 4, when the detailed information page of the first non-fungible token is viewed in the market , the contents of the first content (first attribute value, etc.) corresponding to the first non-fungible token are displayed on the market web page.

A game image, which will be described later, is displayed on the left, and the price of the first non-fungible token, a purchase request button, a second attribute value (P2), and a third attribute value (P3) are displayed on the right.

Examples of the second attribute value (P2) include values such as rank, in-game price, number of likes, evolution level, in-game weight, in-game size, in-game category, in-game ability index, in-game special ability, and number of in-game reinforcements. This can be used.

In a step (S600) of modifying the first attribute value by transacting the first non-fungible token, based on the occurrence of update processing of the first content in the game database 2, the second attribute is in-game data. When the value (P2) is partially modified, the first attribute value can be modified by transacting the first non-fungible token so that this can be confirmed in real time on the market. At this time, the first non-fungible token is temporarily transacted with a management wallet for renewal, and then transacted again with the original owner's wallet of the first non-fungible token, and the data can be updated.

Receiving a purchase request message for the first non-fungible token (S700); and receiving a sales acceptance message corresponding to the purchase request message (S800); receiving a purchase request and a sales acceptance for a certain first non-fungible token from the buyer terminal 4 and the seller terminal 3, respectively. , you can transmit it to the other terminal to create a mutual transaction.

In the step (S900) of transacting the first non-fungible token based on the sale acceptance message, when the seller accepts the sale in response to the purchase request, the first non-fungible token is transferred from the seller's wallet to the buyer's wallet. You can transact with .

The first attribute value includes: a second attribute value (P2) that is game environment data recorded in the game database 2; and a third attribute value (P3), which is a scarcity index of the first non-fungible token calculated based on the second attribute value (P2) of the third non-fungible tokens registered in the market.

The third attribute value (P3) may include the name of the first content, rarity, image category (Synergies), etc., as shown in FIG. 4.

In addition, the step of modifying the first attribute value (S600) includes: checking whether the designated first label among the second attribute values (P2) is modified (S601); Generating a second non-fungible token based on the second content corresponding to the modified first label (S602); Temporarily storing the first attribute value of the first content as a fourth attribute value (S603); Substituting the fifth attribute value of the second content with the first attribute value (S604); and replacing the temporarily stored fourth attribute value with a fifth attribute value of second content (S605).

In the step (S601) of checking whether the first label designated among the second attribute values (P2) is modified, among the labels representing various numerical values/indexes/values, data for evolving/transforming/transforming the first content is designated. Only check whether the first label has been modified.

For example, when there are labels such as item name, item grade, in-game price, number of likes, number of remaining evolutions, etc., if the remaining evolution count data changes, this means that an evolution has occurred, and based on this when the remaining evolution count data is modified. The evolution of the first content is reflected in the first non-fungible token.

Generating a second non-fungible token based on the second content corresponding to the modified first label (S602); generating a second non-fungible token for the second content that is data after evolution of the first content creates .

Afterwards, the first attribute value of the first content, which still remains as pre-evolution data, is temporarily stored as the fourth attribute value, and the fifth attribute value of the second content, which is post-evolution data, is replaced with the first attribute value, thereby replacing the first attribute value with the first attribute value. The content and the first non-fungible token are processed to store the fifth attribute value, which is data after evolution.

Next, the second content is overwritten with the fourth attribute value, which is the temporarily stored pre-evolution data, so that the second content and the second non-replaceable token correspond to the pre-evolution data.

Based on these steps, the uniqueness (non-fungibility) of the first non-fungible token can be maintained and the evolution information can be recorded on the blockchain even for the first content that has changed through evolution/change/transformation, etc. within the game.

The step of displaying the first attribute value includes: generating a fifth attribute value display page of the second non-fungible token; And it may further include displaying a link to access the fifth attribute value display page in the sales information of the first non-fungible token.

Accordingly, the user can access the detailed information page of the second non-fungible token, which is data before evolution, from the detailed information (sales information) page of the first non-fungible token.

Transacting the first non-fungible token (S900) includes: transacting the second non-fungible token corresponding to the first non-fungible token and the first non-fungible token with the wallet address of the purchase requester; It can be included.

Accordingly, the second non-fungible token is linked to the first non-fungible token as a subordinate non-fungible token subordinate to the evolved first non-fungible token, and can be transacted together as a set when trading the first non-fungible token.

It may further include calculating the third attribute value (P3).

The second attribute value (P2) may include: a predetermined in-game image (I).

The third attribute value (P3) may include an 'image similarity value', which is a similarity value between the in-game image (I) of the first content and the in-game image (I) of the third content previously registered in the market.

Here, the third content refers to in-game content that has previously been converted into NFT according to the above-described steps and registered in the market.

The step of calculating the third attribute value (P3) is: extracting the in-game image (I) of the third non-fungible tokens registered in the market, and Calculating matrices (S1); Extracting an in-game image (I) of the first non-fungible token and calculating a second matrix for the first non-fungible token (S2); Comparing the second matrix with each of the first matrices, and extracting a third matrix with the highest similarity to the second matrix among the first matrices (S3); and specifying the similarity between the second matrix and the third matrix as an image similarity value (S4).

In a step (S1) of extracting in-game images (I) of the third non-fungible tokens registered in the market and calculating first matrices for each of the third non-fungible tokens registered in the market (S1), The in-game image (I) of the third non-fungible tokens (non-fungible tokens already registered in the market as NFT) corresponding to the contents is extracted and converted into data (first matrix calculated).

In the step (S2) of extracting the in-game image (I) of the first non-fungible token and calculating a second matrix for the first non-fungible token, a second matrix corresponding to the first content newly registered in the market is provided. 1 Extract the in-game image (I) of the non-fungible token and convert it into data (calculate the second matrix).

In the step (S3) of comparing the second matrix with each of the first matrices and extracting a third matrix with the highest similarity to the second matrix among the first matrices, a plurality of first matrices and the first matrix are extracted. 2 Compare the matrices and determine the degree of similarity for each. Afterwards, a third matrix that is most similar to the second matrix is extracted from among the first matrices.

In the step (S4) of specifying the similarity between the second matrix and the third matrix as an image similarity value, the newly registered first content is designated by specifying the similarity between the second matrix and the third matrix as an image similarity value. Image similarity is calculated based on the most similar data among the existing in-game images (I) of the in-game image (I).

The step of calculating the first matrices and the step of calculating the second matrix include: converting the color of each pixel of the in-game image (I) to be calculated into a matrix into an integer; expressing the color of each pixel converted to an integer as a third matrix; converting the third matrix into a fourth matrix that is a square matrix of a specified first size; and calculating the fourth matrix as a result value.

In the step of converting the color of each pixel of the matrix calculation target in-game image (I) into an integer (Integer), for each pixel of the in-game image (I) file (jpeg, png, bmp, gif, etc.), the color stored in that pixel Converts to an integer value. For example, the color 0F21F0 (hexadecimal) expressed as a hex code (color code; #RRGGBB) can be converted to the decimal integer 991728.

A predetermined integer matrix may be generated according to the step of expressing the color of each pixel converted to an integer as a predetermined third matrix.

converting the third matrix into a fourth matrix that is a square matrix of a specified first size; and calculating the fourth matrix as a result value; converting the third matrix into a square matrix of the first size that serves as a standard for determining similarity.

Here, the first size may be in the form of n

For example, a third matrix of size 256

The specific process for converting the size of the matrix will be described later.

In addition, the step of converting the third matrix into a fourth matrix, which is a square matrix of a designated first size, includes: replacing 0 with 1 among the values of each component of the third matrix; dividing each component of the third matrix to generate a number of fifth matrices corresponding to the first size; calculating a first representative value that is the sum of components of each of the fifth matrices; calculating a second representative value that is a product of components of each of the fifth matrices; calculating a third representative value that is an average value of each component of the fifth matrices; calculating a fourth representative value that is the determinant of each of the fifth matrices; calculating a fifth representative value that is the sum of diagonal components of each of the fifth matrices; generating a 4-1 matrix of the first size based on the first representative values; generating a 4-2 matrix of the first size based on the second representative values; generating a 4-3 matrix of the first size based on the third representative values; generating a 4-4th matrix of the first size based on the fourth representative values; generating a 4-5th matrix of the first size based on the fifth representative values; generating a sixth matrix by adding the 4-1st to 4-5th matrices; and designating the sixth matrix as the fourth matrix.

In the step of replacing 0 with 1 among the values of each component of the third matrix, preventing loss of data due to '0' data in a predetermined process, such as calculating a second representative value among the steps described later. To do this, all 0s in each component of the third matrix are replaced with 1.

In the step of dividing each component of the third matrix to generate a number of fifth matrices corresponding to the first size, the third matrix is divided into predetermined sizes to generate a plurality of fifth matrices.

For example, to convert a third matrix of size 256 At this time, some elements of the third matrix may be included in multiple fifth matrices.

More specifically, when there is a third matrix of size 6

By dividing the third matrix into 2

In the above example, the [3, 6, 9] and [13, 16, 19] components are included in duplicate in the two fifth matrices, respectively.

As described above, classifying the matrix while allowing overlap of components without missing components can be performed according to general common sense.

In the step of calculating a first representative value that is the sum of the components of each of the fifth matrices, a first representative value that is a value that can represent the properties of each fifth matrix is calculated from a plurality of separately generated fifth matrices. It is calculated by adding up all the components of each fifth matrix.

In the step of calculating a second representative value that is a product of the components of each of the fifth matrices, a second representative value that is a value that can represent the properties of each fifth matrix from the plurality of separately generated fifth matrices is calculated. It is calculated by multiplying all the components of each fifth matrix.

In the step of calculating a third representative value, which is an average value of the components of each of the fifth matrices, a third representative value is a value that can represent the properties of each fifth matrix from a plurality of separately generated fifth matrices. is calculated by averaging all the components of each fifth matrix.

In the step of calculating a fourth representative value that is a value of the determinant of each of the fifth matrices, a fourth representative value that is a value that can represent the properties of each fifth matrix is calculated from a plurality of separately generated fifth matrices. It is calculated by calculating the determinant for the fifth matrix.

In the step of calculating a fifth representative value that is the sum of diagonal components of each of the fifth matrices, the fifth representative value is a value that can represent the properties of each fifth matrix from a plurality of separately generated fifth matrices. is calculated by adding up only the diagonal components of each fifth matrix.

generating a 4-1 matrix of the first size based on the first representative values; generating a 4-2 matrix of the first size based on the second representative values; generating a 4-3 matrix of the first size based on the third representative values; generating a 4-4th matrix of the first size based on the fourth representative values; and generating a 4-5th matrix of the first size based on the fifth representative values; in the step, based on the calculated first to fifth representative values, the above-described third matrix is the fifth It is processed to be converted into the 4-1st matrix to the 4-5th matrix through the matrix.

generating a sixth matrix by adding the 4-1st to 4-5th matrices; and designating the sixth matrix as a fourth matrix. In this step, the fourth matrix, which is final data, is calculated by summing the first to fifth representative values for each component of the matrix of the first size.

According to this process, in-game images (I) of different sizes can be judged on their similarity to each other according to the same process.

In other words, a first in-game image (I) of size 256 .

The information contained in adjacent pixels is included in the fourth matrix according to the above conversion process, and the fourth matrix containing all the first to fifth representative values calculated according to different calculation methods is the in-game image ( It reflects the characteristics of I) more accurately.

In addition, the step of calculating the similarity between matrices includes: calculating a seventh matrix by performing a difference operation on the matrix to be compared; calculating the absolute value of the determinant of the seventh matrix; and specifying the absolute value of the determinant of the seventh matrix as the similarity between the matrices. The closer the similarity value between the matrices is to 0, the more similar the matrices can be evaluated.

Here, the 'step of calculating the similarity between matrices' refers to the above-described 'comparing the second matrix with each of the first matrices, and selecting a third matrix with the highest similarity to the second matrix among the first matrices. Extracting step (S3); Or a step (S4) of specifying the similarity between the second matrix and the third matrix as an image similarity value; It means each.

In other words, the matrices to be compared are each of the first matrices and the second matrix, or the second matrix and the third matrix.

In the step of calculating the seventh matrix by calculating the difference between the matrices to be compared, each component of the two matrices to be compared is calculated as a difference, and since the absolute value of the determinant is used later, the order of subtracting which matrix from which matrix is It's irrelevant.

The higher the similarity between matrices, the closer the absolute value of the determinant is to 0. Therefore, as the similarity value between matrices approaches 0, matrices are evaluated as similar to each other, and as the similarity value between matrices increases, matrices are evaluated as different from each other.

Transacting the first non-fungible token (S900) includes: transacting the first non-fungible token from a seller's wallet to an intermediary wallet; monitoring whether the first non-fungible token seller is connected to the game; Sending an in-game message requesting sales confirmation to the seller; monitoring whether the first non-fungible token purchaser is connected to the game; Sending an in-game message requesting purchase confirmation to the purchaser; and when both the in-game message for the sales confirmation request and the in-game message for the sales confirmation request are accepted, transacting the first non-fungible token from the brokerage wallet to the buyer's wallet.

The step of transacting the first non-fungible token from the seller's wallet to the brokerage wallet; creating a separate management/brokerage wallet, which is a separate entity from the seller and the buyer, to confirm the transaction between the seller and the buyer, which will be described later. Transactions are temporarily made to the above brokerage wallet until the process is completed.

monitoring whether the first non-fungible token seller is connected to the game; And sending an in-game message to the seller requesting sales confirmation; in the step, it is confirmed whether the seller is connected to the in-game, and a predetermined in-game message is sent to the seller based on the game connection status trigger to obtain a non-fungible token and Receive confirmation from the seller whether in-game goods such as items/characters are sold.
