Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and more specifically, to a blind box configuration method and a blind box sales system based on blockchain. Background Art

[0002] Blind boxes refer to toy boxes where consumers cannot know the specific product styles in advance. They have random properties. Only when consumers open them will they know what style of product they have drawn. Blind boxes contain multiple different series. The initial number of blind boxes corresponding to a whole box in each series is different, and the blind boxes in each whole box are unique. After a blind box is drawn, it will not be automatically replenished until the whole box is drawn.

[0003] However, with the rapid development of the blind box economy, the credibility of online blind box purchases has gradually been exposed. Due to the opacity of online purchases, companies can secretly manipulate the blind box styles that consumers draw. For example, when consumers intend to draw a brand new box, no matter which blind box the consumer draws, it will show that they have drawn an unpopular style. This will make consumers distrust blind box companies and question the fairness of drawing blind boxes. Summary of the invention

[0004] The present application provides a blind box configuration method and a blind box sales system based on blockchain, which is conducive to improving the credibility of blind box products.

[0005] In the first aspect, a blind box configuration method based on blockchain is provided, the method comprising: a packaging node receives a configuration request from an enterprise node, the configuration request carries a series identification number and a random number of the blind box.

[0032] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0033] Before introducing the blockchain-based blind box configuration method and blind box sales system provided in the embodiments of the present application, the following points are explained.

"At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0037] Figure 1 1 is a schematic diagram of a blind box sales system 100 based on blockchain provided in an embodiment of the present application. The system 100 includes a consumer terminal 101, an enterprise node 102, a supervision node 103, a packaging node 104, and three verification nodes 105. It should be understood that the system 100 takes three verification nodes 105 as an example, and the embodiment of the present application does not limit the number of verification nodes.

[0038] Among them, the system 100 includes a blockchain network, and the blockchain network includes an enterprise node 102, a supervision node 103, a packaging node 104 and three verification nodes 105.

[0039] In the embodiment of the present application, the consumer terminal 101 is mainly used to provide consumers with an entry for interacting with the blockchain network.

[0040] Enterprise node 102 is a blind box enterprise node, which is used to send product configuration requests and receive purchase requests from consumer terminals.

[0041] The supervision node 103 is used to receive the block information synchronized by the packaging node 104, receive the verification request initiated by the consumer terminal in the online extraction process, and respond to and forward the verification request.

[0042] The packaging node 104 is used to receive requests from the enterprise node 102 or the regulatory node 103, perform hash calculations on the relevant data, and package them to generate blocks, and synchronize the block information to other nodes in the blockchain network, that is, the block information between all nodes in the blockchain network is consistent.

[0043] The verification node 105 can verify the synchronized block information.

[0044] The packaging node 104 and the verification node 105 can be collectively referred to as a consensus node, and the packaging node 104 and the verification node 105 can be switched at will, and the switching method and cycle can vary depending on the consensus algorithm.

[0045] The packaging node 104 and / or the verification node 105 locally stores a series style table, which records the corresponding relationship between the series identification number and the style identification number.

[0046] Figure 2 is a schematic diagram of a block provided in an embodiment of the present application, which can be applied to the above-mentioned blind box sales system 100. Figure 2 As shown, the block includes a block body and a block header. The block header includes: previous hash value, block height, timestamp, root hash value, series identification number, whole box identification number, number of blind boxes in the whole box. The block body includes a blind box information package and a Merkle tree of the hash value of the blind box. Among them, the Merkle number includes the hash value of the blind box, the hash value and the root hash value.

[0047] For example, Figure 2 As shown, blind box information package 0, blind box information package 1, blind box information package 2, and blind box information package 3 are respectively calculated by hashing to obtain the blind box's hash value 0, the blind box's hash value 1, the blind box's hash value 2, and the blind box's hash value 3. The blind box's hash value 0 and the blind box's hash value 1 are calculated by hashing to obtain the hash value 01, the blind box's hash value 2 and the blind box's hash value 3 are calculated by hashing to obtain the hash value 23, and the hash value 01 and the hash value 23 are then calculated by hashing to obtain the root hash value.

[0048] In an embodiment of the present application, a block represents a whole box. When a blind box in a whole box is extracted, the block information of the whole box changes, and the packaging node generates a new block.

[0049] Among them, the root hash value represents the root hash value of the block, that is, the Merkle tree root calculated by the block body. The previous hash value represents the root hash value of the previous block of the block. The block height is an increasing sequence of natural numbers, which is used to confirm the order of blocks. The timestamp is the time when the block is packaged. The series identification number represents the unique identification number calibrated by the enterprise node for a series of blind boxes, which is used to identify the series to which the blind box in the whole box represented by the block belongs. The identification number of the whole box uniquely identifies the whole box represented by the block. It is consistent with the block height during the initial configuration, and the identification number of the whole box remains unchanged afterwards. The number of blind boxes in the whole box represents the number of blind box information packages included in the block.

[0050] Among them, the blind box information package includes the whole box random number (Nonce) and the style identification number. The Merkle tree of the blind box information package and the hash value of the blind box is used to calculate the Merkle tree root, that is, the root hash value in the block header. The whole box random number is a non-repeating random number submitted by the enterprise node when configuring the whole box. Each whole box corresponds to a random number. The random number of each whole box is different. Figure 2 The random numbers in each blind box information package in the blocks shown are consistent. The style identification number can uniquely identify a blind box style, and consumers can know the product style corresponding to the style.

[0051] When consumers draw blind boxes, they can choose the blind box's hash value 0, the blind box's hash value 1, the blind box's hash value 2, and the blind box's hash value 3 as selection objects for blind selection, so that consumers can make choices without knowing the style of the blind box. Calculating the Merkle tree based on the blind box's hash value is also helpful in preventing block information from being tampered with.

[0052] Figure 3 is a schematic flow chart of a blind box configuration method 300 based on blockchain provided in an embodiment of the present application. The method 300 can be applied to Figure 1 The blockchain-based blind box sales system 100 shown below includes:

[0053] S301, the enterprise node sends a configuration request to the packaging node, the configuration request carries the series identification number and random number of the blind box. Correspondingly, the packaging node receives the configuration request.

[0054] S302, the packaging node determines the style identification number corresponding to the series identification number according to the series identification number and the locally stored series style table, and generates at least one block according to the style identification number. Each block in the at least one block corresponds to a whole box, and the whole box includes at least one blind box with the same series identification number and different style identification numbers. Each block includes a block header and a block body. The block header includes the series identification number, the root hash value, the block height, the whole box identification number, and the number of blind boxes in the whole box. The block body includes the style identification number and a random number of the blind box.

[0055] S303, the packaging node sends the block information of the at least one block to the multiple verification nodes. Correspondingly, the multiple verification nodes receive the block information of the at least one block.

[0056] S304, multiple verification nodes verify the style of the blind box in the block information according to the block information of the at least one block and the series style table. Multiple verification nodes locally store the series style table.

[0057] S305, multiple verification nodes send verification results to the packaging node, where the verification results include verification passed or verification failed. Accordingly, the packaging node receives the verification results from the multiple verification nodes.

[0058] S306, when multiple verification nodes have verified the block information of the at least one block, the packaging node synchronizes the block information of the at least one block to the enterprise node and the supervision node.

[0059] It should be understood that in the embodiment of the present application, the verification of the block information by the verification node may include: verifying the hash value of the blind box in the block information. Since the styles of the blind boxes in the whole box are different, the style identification numbers of the blind boxes are different, and the hash values ​​of the blind boxes calculated according to the style identification number of the blind box and the random number of the whole box are different. The verification node can determine the style identification number of the blind box corresponding to the series identification number according to the locally stored series style table, and then calculate the hash value of the blind box according to the blind box style identification number and the random number. If the hash value of the blind box calculated by the verification node is consistent with the hash value of the blind box recorded in the block information, then the verification is passed. If the enterprise node replaces the style identification number under a certain series, the verification may not pass. If each verification node passes the verification, it means that the process of configuring the blind box by the enterprise node is fair and credible, and then the block information of the at least one block can be synchronized to the supervision node and the enterprise node.

[0060] In the embodiment of the present application, the packaging node can configure a new whole box of blind boxes according to the configuration request of the enterprise node, and record the block information in the blockchain for users to select and extract blind boxes. The existence of multiple verification nodes makes the configuration of blind box products more fair. If a blind box company replaces the blind box style in a series in secret, or the styles of blind boxes in a whole box are all the same, then it will not be able to pass the verification of the verification node, which is conducive to improving the fairness of selling blind box products.

[0061] Exemplarily, a commodity series with a series identification number of A includes 4 different styles of commodities, and each style of commodity corresponds to a style identification number, for example, a, b, c, and d are used to represent the style identification numbers of 4 different styles of commodities respectively. During the configuration process of a new whole box of blind boxes, the packaging node can configure 4 different styles of commodities in the same series into a whole box, that is, a whole box includes 4 different styles of blind boxes. It should be understood that when configuring a whole box, the packaging node may configure multiple whole boxes, each with a corresponding identification number. For example, a commodity series with a series identification number of A is finally configured into 8 whole boxes, and the identification numbers of the 8 whole boxes are 1, 2, 3, 4, 5, 6, 7, and 8, respectively. Each whole box includes 4 different styles of blind boxes corresponding to the style identification numbers of a, b, c, and d, respectively, of the A series.

[0062] It should be understood that when configuring a whole box, the enterprise node can generate a random number for the packaging node to perform hash calculation. After a new whole box is configured, if the packaging node configures another new whole box, the enterprise node needs to regenerate a random number.

[0063] As an optional embodiment, S302 includes: the packing node packs the style identification number and the random number to obtain the blind box information package of each block. The packing node calculates the hash value of the blind box information package of each block to obtain the hash value of the blind box of each block. The packing node obtains the root hash value of each block based on the hash value of the blind box of each block.

[0064] In an embodiment of the present application, the packaging node can calculate the root hash value of each block based on the Merkle tree, which is helpful in preventing enterprise nodes from tampering with the style of the blind box.

[0065] After the blind box configuration is completed, consumers can draw the blind box online or offline. Figure 4 Introduce a blind box extraction method.

[0066] Figure 4 is a schematic flow chart of a blind box extraction method 400 based on blockchain provided in an embodiment of the present application. The method 400 can be applied to Figure 1 The blockchain-based blind box sales system 100 shown. Method 400 can be performed after the above method 300. Method 400 includes the following steps:

[0067] S401, the consumer terminal sends a blind box extraction request to the enterprise node, the blind box extraction request carries the target series identification number. Correspondingly, the enterprise node receives the blind box extraction request.

[0068] S402: The enterprise node determines at least one candidate whole box from a plurality of whole boxes corresponding to the target series identification number.

[0069] S403, the enterprise node sends the identification number of the at least one candidate whole box to the consumer terminal, and the number of blind boxes of each candidate whole box in the at least one candidate whole box is greater than 0. Accordingly, the consumer terminal receives the identification number of the at least one candidate whole box.

[0070] S404: The consumer terminal selects a target whole box from at least one candidate whole box based on the identification number of the at least one candidate whole box.

[0071] S405, the consumer terminal sends the identification number of the target whole box to the enterprise node. Correspondingly, the enterprise node receives the identification number of the target whole box.

[0072] S406, the enterprise node determines the blind boxes included in the target whole box according to the identification number of the target whole box.

[0073] S407, the enterprise node sends the hash value of the blind box included in the target full box to the consumer terminal. Correspondingly, the consumer terminal receives the hash value of the blind box included in the target full box.

[0074] S408, the consumer terminal selects a target blind box from the blind boxes included in the target whole box based on the hash value of the blind boxes included in the target whole box.

[0075] S409, the consumer terminal sends a purchase request to the enterprise node, the purchase request carries the hash value of the target blind box. Correspondingly, the enterprise node receives the purchase request.

[0076] S410, the enterprise node obtains the style identification number of the target blind box from the block based on the hash value of the target blind box.

[0077] S411, the enterprise node sends the style identification number of the target blind box to the consumer terminal. Correspondingly, the consumer terminal receives the style identification number of the target blind box.

[0078] S412, the consumer terminal displays the style identification number of the target blind box to the consumer.

[0079] The above method 400 introduces the process of consumers drawing blind boxes. In the drawing process, the consumer can first select the target series identification number through the consumer terminal to determine the series of goods to be drawn, and then the enterprise node can provide the consumer with at least one candidate whole box with a non-zero number of blind boxes according to the target series identification number. After the consumer selects a target whole box from at least one candidate whole box through the consumer terminal, the enterprise node can provide the consumer with a hash value of the blind box in the target whole box according to the target whole box. The consumer cannot know the style of the corresponding blind box product through the hash value of the blind box, which is conducive to consumers to make blind selections and improve the fairness of blind box drawing.

[0080] After the blind box drawing is over, consumers may be dissatisfied with the style of the blind box drawn, or question the fairness of the blind box drawing process. At this time, consumers can verify the blind box drawn.

[0081] As an optional embodiment, the consumer terminal sends a verification request to the supervision node, and the verification request carries the identification number of the target whole box. The supervision node receives the verification request, determines the initial block recorded when the target whole box is first configured according to the identification number of the target whole box, and sends the block information of the initial block to the consumer terminal. The consumer terminal receives the block information of the initial block and performs verification based on the block information of the initial block.

[0082] In the embodiment of the present application, due to the identification number and block height of the whole box at the time of initial configuration, the supervisory node can quickly find the initial block recorded when the target whole box is initially configured according to the identification number of the target whole box, and send the block information of the initial block to the consumer terminal. The consumer can verify whether the product style provided by the enterprise node is consistent with the style drawn by himself according to the random number in the blind box information package and the style identification number of the target blind box.

[0083] For example, the consumer can calculate the hash value of the blind box based on the random number of the target whole box and the style identification number of the blind box displayed to the consumer, and determine whether the calculated hash value of the blind box is consistent with the hash value of the target blind box in the block information of the initial block. If they are consistent, it means that the blind box drawing is fair.

[0084] Exemplarily, the consumer can also calculate the root hash value based on the hash value of the blind box displayed to the consumer to verify whether the blind box information package has been tampered with.

[0085] In one possible scenario, after the blind box drawing is completed, the consumer verifies the drawing. After verification, the packaging node can generate a new block corresponding to the target whole box.

[0086] As an optional embodiment, the supervision node sends the verification request to the packaging node. The packaging node receives the verification request, determines the initial block recorded when the target whole box is first configured according to the identification number of the target whole box, and retains the series identification number and the whole box identification number in the block information of the initial block, and generates a first new block with an empty block body, an empty root hash value, and a number of remaining blind boxes in the whole box of 0. The packaging node synchronizes the block information of the first new block to the enterprise node, the verification node, and the supervision node.

[0087] In the embodiment of the present application, since the consumer has initiated verification to obtain the block information of the initial block corresponding to the target whole box, the block information of the initial block includes the corresponding relationship between the hash value of the blind box and the blind box style, so the blind box in the target whole box is transparent to the consumer. In order to avoid unfair blind box extraction, the packaging node can generate a first new block with an empty block body, an empty root hash value, and 0 remaining blind boxes in the whole box after receiving the verification request. Only the series identification number and the whole box identification number in the block information of the initial block are retained in the first new block. The first new block generated in this way indicates that the extraction of the target whole box has ended and cannot be extracted by subsequent consumers.

[0088] In another possible scenario, the consumer does not verify the blind box drawing after the blind box drawing is completed. In this case, the packaging node can also generate a new block corresponding to the target whole box after the blind box drawing is completed.

[0089] As an optional embodiment, the enterprise node sends the purchase request to the packaging node, and the purchase request carries the identification number of the target whole box and the hash value of the remaining blind boxes in the target whole box.
