3 is a conceptual diagram showing a product management procedure based on a blockchain according to an embodiment of the present invention.

3, a method of setting a product management plan according to product planning information on a blockchain is disclosed. In particular, a method for establishing a contract with an initial buyer node based on initially planned product information is disclosed.

Referring to FIG. 3, a product management plan is set by processing product planning information 350 based on a block chain code installed in a shopping mall node (or blockchain) 320, and the set product management plan is a block chain (or separately It may be stored in a data storage unit (eg, a key value store (KVS).) When the product management plan 360 recorded in the separate data storage unit 340 is stored, the blockchain is a separate data storage unit. The hash value of the recorded data may be stored. Hereinafter, in the embodiment of the present invention, the expression that information (or data) is uploaded on the blockchain is when the hash value of the information (or data) is uploaded on the blockchain. It can be used in the inclusive sense.

As described above, the product planning information 350 may include product initial sales information, order minimum quantity information, product verification information, and product delivery information. The product management plan 360 may include product initial sales information, order minimum quantity information, product verification information, and product management information on the blockchain according to product delivery information.

Based on the initial sales information of the product delivered to the shopping mall node, the initial sales amount and the contract amount according to the initial sales amount (for example, 10% of the initial sales amount), the initial sales period, and the contract amount deposit address may be determined. Information related to the initial sales amount, contract amount, and contract amount deposit address set on the blockchain is uploaded, and the uploaded initial sales amount, contract amount, and contract amount deposit address can be disclosed to users who use the shopping mall on the shopping mall platform. The buyer node can send cryptocurrency corresponding to the contract amount to the public deposit address and transmit purchase consent information, and a purchase contract can be established based on the transferred cryptocurrency and purchase consent information. According to an embodiment of the present invention, the amount of cryptocurrency deposited as a contract amount during the contract period may be adjusted according to the market price.

Specifically, initial sales amount information, contract amount information, initial sales period information, and contract amount deposit address information may be stored on the first block based on the initial price information of the product and the blockchain code.

The initial sales amount and contract amount may be processed based on a stable coin, or may be processed based on a non-stable coin. The product planning node may select the stable coin or the non-stable coin to perform processing on the initial sales amount and contract amount.

In the case of stable coins, the price volatility is not large, so if there is volatility within the set price range, the initial sale price/contract amount may not change. In the case of processing based on a non-stable coin, the initial selling price based on the blockchain code may continuously change according to a certain time. For example, the price information of the cryptocurrency is transmitted from the external exchange node at a predetermined period (or block generation unit), and the newly updated initial sale price/contract amount can be determined based on the blockchain code.

The setting cycle may be changed according to the volatility of the cryptocurrency by determining the volatility of the cryptocurrency based on the blockchain code. If price volatility is determined based on the price information of the cryptocurrency delivered by the external exchange node and the price volatility is above a threshold, the set period of initial purchase price may be changed based on the blockchain code. Based on the above blockchain code, the initial purchase price may continuously fluctuate during the contractable period on the blockchain.

According to an embodiment of the present invention, when a buyer node deposits cryptocurrency within a certain threshold block based on a change point of the cryptocurrency price, a processing method for the cryptocurrency is disclosed.

The number of critical blocks determined based on the reference block, which is a change point of the price of the cryptocurrency, may be determined based on the processing speed of the blockchain network. For example, based on the block code, the number of critical blocks is determined in consideration of the change time of the contract amount and the processing speed of the blockchain network, and in the case of cryptocurrency corresponding to the contract amount before the change delivered within the critical block, It may be recognized that the amount of the contract has been deposited. If the price of the cryptocurrency is increased, the refund for the difference proceeds to the buyer node, and when the price of the cryptocurrency is decreased, the additional amount may not be requested from the buyer.

Alternatively, it may be set as a temporary suspension period of the contract separately on the previous block of the threshold number and the subsequent block of the threshold number based on the reference block, which is the time point of change of the cryptocurrency price. The contract occurring on the previous block of the threshold number and the subsequent block of the threshold number may be invalidated in consideration of the block generation speed.

In addition, according to an embodiment of the present invention, the changed initial purchase price information and the deposit address information are interlocked, and whether the amount corresponding to the changed initial purchase price is deposited in consideration of the deposit time at the corresponding deposit address is determined by the blockchain code. It can be judged based on. According to the setting of the product planning node 300, the cryptocurrency received as a contract amount may be converted into legal money or converted into cryptocurrency after a certain period of time. Alternatively, if the volatility is more than a certain amount, it may be set based on the blockchain code so that the cryptocurrency is directly converted into legal currency.

4 is a conceptual diagram showing a method for setting an initial sales period according to an embodiment of the present invention.

4, a method for setting an initial sales period on a blockchain is disclosed.

Referring to FIG. 4, it is possible to determine that the contract processed from the first block to the n-th block, which is the starting point of the contract, is completed by adding time information according to the setting of the initial sales period. When the initial sales period is set to 7 days, the transaction recorded in the block created from 0 days 0:0:0 to 7 days 0:0:0 seconds in consideration of physical time can be recognized as a valid transaction.

Or, according to an embodiment of the present invention, the initial transaction block 410 and the final transaction block 420 may be set in consideration of separate actual network conditions. After the product is released to the user, the creation time of the first generated block is set as the starting point, and after the starting point, the contract processed on the block created between the initial sales periods (for example, 7 days) is valid. I can judge. The shopping mall node 400 may record the time of publication of the product information on the block and determine the time of creation of the initial transaction block 410 and the initial transaction block 410 based on the information on the recorded block. The block processed during the initial sales period (e.g., 7 days) is valid, and the first block is created after the physically corresponding 7 days based on the time of creation of the initial transaction block 410 Alternatively, the previous block of the first generated block after the time corresponding to 7 days may be determined as the final transaction block 420.

Alternatively, according to an embodiment of the present invention, an initial sales period may be determined based on a time point at which actual data is generated, not on a block basis.

The time of disclosure of the product information by the shopping mall node is recorded on the block and is determined as the initial time, and the final time may be determined by determining the physical time lapse based on the initial time. Only transactions generated between the initial time point and the final time point can be determined to be valid.

According to an embodiment of the present invention, the product planning node may set a product initial sales period by selecting one of the period setting options from the above period setting. Alternatively, according to an embodiment of the present invention, the shopping mall node may be set differently according to the trend of product sales in consideration of product sales. If the initial contract completion rate is less than or equal to the threshold rate, the time of the initial sales period is selectively adjusted relatively later (for example, after the product is released to the user, when the first generated block is created), the relative time You can set the range. When the number of final contracts in the borderline range determines whether the product is finally produced or when the final contract in the borderline range exceeds the orderable amount, the end time of the initial sales period may be selectively adjusted relatively later.

5 is a conceptual diagram showing a product plan setting method according to an embodiment of the present invention.

5, a method for verifying a product based on product verification information on a blockchain is disclosed.

Referring to FIG. 5, the product verification information 550 may include date information for each verification step and checklist information for each verification step.

Based on the product verification information 550, a verification step date and a verification step checklist may be set on the blockchain.

At the verification step date, the product planner node 520 may submit verification data 560 according to the verification step checklist, and a determination on the product production execution rate may be performed on the blockchain. For example, when the product planner node 520 produces and sells 1000 planned products A, the verification data for verifying that 1000 planned products A can be produced/sold within the deadline is blocked during the verification step by a verification step. You can upload it on the chain.

A separate verification node 540 is selected for verification of the production items for each verification step, and verification by the verification node 540 may be performed. The verification node 540 is determined based on the existing activity history, the number of cryptocurrencies associated with the shopping mall platform owned by the verification node 540, and some verification nodes 540 may be randomly selected.

The first verification node group may include a verification node randomly selected from among verification nodes that have exceeded a certain threshold level based on the existing activity history information and the number of cryptocurrency related to the shopping mall platform owned by the verification node. Existing activity history information is a history of existing activity as a verification node, and includes information on whether or not the product is correctly verified, and the number of cryptocurrency information may refer to the amount of cryptocurrency to be used in the platform to be described later. have. A node that can have a relatively good influence on the shopping mall platform through accurate determination considering the existing activity history information and the number of cryptocurrencies may be selected as the first verification node group. The first verification node may receive cryptocurrency in exchange for verification.

The second verification node group may be a group including a randomly selected second verification node. The second verification node may be nodes that request to participate in the verification operation by selecting nodes other than the first verification node among the existing nodes, and may accept the request. Alternatively, the second verification node may be a node that pays a certain cryptocurrency and requests to perform a role as a verification node. When the second verification node performs verification by a predetermined time limit, it can receive additional cryptocurrency in exchange for the transmitted cryptocurrency and verification, but if it does not perform verification by the specified time limit, the second verification node sends the encrypted You may not be able to get the money back.

The first verification result of the first verification node group and the second verification result of the second verification node group may be transmitted on the block and determined collectively or individually to finally determine whether to pass the verification step. For example, the verification result may be integrated by applying the first weight to the first verification result and the second weight to the second verification result based on the blockchain code. Whether or not the product verification process passes may be determined based on the integrated verification result. For example, when a verification node having a first threshold ratio or higher determines to pass, the verification procedure may pass. When the verification node that is greater than or equal to the second threshold ratio and less than the first threshold ratio determines to pass, revalidation may be performed by requesting additional data from the product planning node. If the verification node below the second threshold ratio determines to pass, the verification procedure may be determined to fail.

According to an embodiment of the present invention, a method for selling a product based on a blockchain includes a step in which a shopping mall platform processes input product planning information based on a blockchain code installed in a shopping mall node, and a shopping mall platform based on the blockchain code. It may include performing an initial sale of the product according to the processed product planning information, and performing a product verification process according to the processed product planning information based on the block chain code of the shopping mall platform.

Product planning information includes product initial sales information, product verification information, and product planning information and product result information processing result information will be stored on the blockchain created in the blockchain network including the shopping mall node operating the shopping mall platform. Can.

The step of performing the initial sale of the product includes the step of the shopping mall platform uploading the initial sale information of the product and the product sale information determined based on the blockchain code, and the product sale information includes the contract amount and the cryptocurrency deposit address according to the initial sale price. It includes information on, and the purchase contract of the product can be established by depositing the cryptocurrency according to the contract amount from the buyer node to the cryptocurrency deposit address.

The product sales information further includes information on the initial sales period, and the initial sales period may be set based on the initial transaction block and the final transaction block in consideration of the blockchain network situation.

In addition, the shopping mall platform includes the step of performing a product verification procedure determined based on the product verification information and the block chain code, wherein the product verification information includes date information for each verification step and checklist information for each verification step, and the product verification procedure is a block. It may be performed by a node selected as a verification node among nodes operating on a chain network.

6 is a conceptual diagram showing a consensus structure according to an embodiment of the present invention.

The basic mining node 600 may be a node that has been granted specific mining authority. Such mining authority can be granted by a chaincode installed separately by a setting node. The randomly selected mining node 620 may be a node selectively performable for a mining operation. The random selection mining node 620 may be selected according to a mining period, and may be a node capable of mining operations in a specific mining period. For example, the randomly selected mining node 620 may be a node with a separate chaincode installed to enable mining operation only for a certain mining period, and optionally operates as a mining node during a specific mining period through a separate trigger. It can be a node that can.

According to an embodiment of the present invention, transaction verification and block generation procedures may be performed by n basic mining nodes 600 and m randomly selected mining nodes 620 selected for each mining period.

The ratio of n basic mining nodes 600 and m randomly selected mining nodes 620 may be set differently according to a processing speed of a required transaction. When the size of the generated transaction is in the range of a or more and less than or equal to b, n basic mining nodes 600 and m randomly selected mining nodes 620 may be utilized as a whole to perform the mining procedure. In addition, when the size of the generated transaction is in the range of b to d or less, n'selected basic mining nodes among n basic mining nodes 600 and m'selected random selection among m random selection mining nodes 620 The mining node 620 may be utilized in full and the mining procedure may be performed. In addition, if the size of the generated transaction is in the range of d to e or less, n'' selected basic mining nodes 600 among n'basic mining nodes 600 and m'randomly selected mining nodes 620 ) Among m''selected basic mining nodes 620 may be utilized to perform the mining procedure.

That is, as the amount of transactions to be processed increases, the number of mining nodes can be adaptively reduced for faster processing, so that transactions can be processed faster.

The default mining node 600 selected when changing from n to n'or n'' again and the random selection mining node 620 selected when changing from m to m'or m'' again are separate privileges. It can be determined by settings.

For example, a specific basic mining node 600 and a random selection mining node 620 based on a chaincode installed based on a hierarchical structure separately set for each of the basic mining node 600 and the random selection mining node 620. Can make it work. Such a hierarchical structure may be adaptively changed within the basic mining node 600 and the randomly selected mining node 620 in consideration of the number of existing block mining, reliability of transaction verification, and the like.

Alternatively, according to an embodiment of the present invention, the basic mining node 600 and the randomly selected mining node 620 are separated through separate channels, or the mining node (the basic mining node 600, the randomly selected mining node 620) You can create a hierarchy of livers. Specifically, the basic mining node 600 is connected based on the first channel, and among the randomly selected mining nodes 620, the node selected as the mining node is selectively connected to the first channel to establish the same channel as the basic mining node 600. Can be maintained. Mining is performed by being connected through the optional first channel may be a default mode. Subsequently, when some of the basic mining node 600 and the randomly selected mining node 620 are selected according to a change in the transaction, only a part of the mining node performs a mining operation by utilizing a specific channel code in the first channel. Can be limited. That is, the default mode for mining is performed based on a node connected based on a channel, and thereafter, hierarchical mining may be performed according to the setting of the channel code.

A plurality of decision node groups such as the decision node group 820 and the third decision node group 830 may be set.

Each of the plurality of judgment node groups may determine whether a futures transaction of the product is possible by determining a futures transaction condition. Each judgment node group may be separately connected to an external node for determining each futures transaction condition to receive data and generate a judgment result based on the received data.

For example, the plurality of first decision nodes included in the first decision node group 810 is a first external node group 815 in order to determine whether the product is a product having a large fluctuation in price according to a period (first condition). ). In addition, the plurality of second determination nodes included in the second determination node group 820 is coupled with the second external node group 825 to determine whether the product has a large variation in price according to a period (first condition). Can be connected. In addition, the plurality of third decision nodes included in the third decision node group 830 is coupled with the third external node group 835 to determine whether the product has a large fluctuation in price according to a period (first condition). Can be connected.

Each of the first external node group 815, the second external node group 825, and the third external node group 835 may be a group in which at least one external node is not the same. The external node group may be determined by collecting information on the web of each judgment node group. For example, when performing web scrolling for data on a first condition, a server of a website capable of obtaining more than a certain data related to the first condition may be set as an external node. Each node group may perform separate web scrolling to determine each external node group to perform a search for the first condition.

The determination result of the plurality of determination node groups may be collected to finally determine whether the first condition is satisfied.

Thereafter, the external included in the plurality of external node groups through the results collected from the threshold number of node groups in the first external node group 815, the second external node group 825, and the third external node group 835 When the collection rate at which the same information is collected at a node becomes a threshold ratio (for example, 70%) or higher, the corresponding external node can be included in only one external node group and excluded from other external node groups. The external node group can be updated according to continuous web scrolling.

By setting an external node in the above manner, judgment on each of a plurality of conditions may be performed.

Further, according to an embodiment of the present invention, data collection may be performed by assigning weights to some of the external nodes. Among the external nodes, hierarchical status is given to nodes that provide high-reliability data, and data transmitted by a specific external node is set to a first layer outer node, a second layer outer node, and a third layer outer node to set a higher layer. The more information collected by the external node, the higher the weight can be assigned to collect the information. Nodes for each layer can differentiate a node collected for each layer by additionally assigning an identifier for each layer to data through separate data classification. At this time, the hierarchy of external nodes is set for each external node group, and the layering results of a plurality of external nodes may be used individually or collectively.

Further, according to an embodiment of the present invention, it is possible to improve the accuracy of data collected from external nodes through feedback on data for each layer. Information collection may be performed from the second layer external node and the third layer external node based on learning about data collected from the first layer external node. Through learning about data collected from nodes outside the first layer, accuracy of information collected from the nodes outside the second layer and the nodes outside the third layer may be improved. Subsequently, the second layer external node and the third layer external node may be changed to a higher layer node through determination of reliability of the periodic external node based on the data collected after the learning result. That is, learning may be applied to collecting information from a lower layer node based on the result of collecting information from a node outside the upper layer, so that it is possible to collect highly reliable information.

In addition, according to an embodiment of the present invention, the collected results to determine whether a futures transaction is possible may be post-processed and used to determine the futures transaction possibility for each product. For example, assuming that a TV is purchased, based on the collected information, it is necessary to consider a possible price fluctuation of the TV, a discount rate of the price of the TV currently provided, and the possibility of preparing a TV quantity. In this case, based on the data collected based on the external node, a determination on a possible price fluctuation range, a discount width, and a possibility of preparing a quantity may be performed based on the data.

For example, clustering may be performed on price information and the distribution of prices may be determined based on clustering. Based on the proximity of price data included in the cluster, determination may be performed based on price distribution within the cluster. . Reliability of the price suggested by the current product planning node can be extracted in consideration of price distribution, price frequency, and density between prices. Based on the cluster center, a price distribution within a first critical distance, a price distribution within a second critical distance, and a price distribution within a third critical distance for each distribution of price data in the cluster may be determined. The greater the critical distance including the price suggested by the product planning node, and the lower the data distribution value within the critical distance, the lower the reliability. The lower the reliability, the more relatively more verification nodes are extracted, so that the product can be traded for futures.

9 is a conceptual diagram illustrating a commodity futures trading method according to an embodiment of the present invention.

9, a method of futures trading of a product subject to futures trading on a blockchain is disclosed.

Referring to FIG. 9, resale of a product purchased through a shopping mall node is possible. However, it is possible to sell the product before the expiration date of the product gift (for example, 7 days before the supply date). Upon expiration of a gift, the final buyer of the product may be the owner of the product. The margin for the sale price of each product can be set using cryptocurrency.

If the seller node and the buyer node match, the buyer node pays a cryptocurrency equivalent to a threshold percentage of the [prepaid price +/- profit (encrypted currency)] price as a deposit, and the deposit is locked. can be locked. The encrypted cryptocurrency cannot be transferred to any other place.

The initial purchaser 900 may perform a shopping mall contract with 10% of the down payment as a down payment.

The primary buyer 910 can perform a 30% contract with only cryptocurrency. The down payment of the primary buyer 910 may be [advance +/- first buyer's margin (encrypted currency)]*30/100.

The secondary buyer 920 can perform a 30% contract with only cryptocurrency. The deposit of the secondary buyer 920 may be [advance +/- primary buyer's profit (encryption currency)]*30/100.

The tertiary buyer 930 can perform a 30% contract with only cryptocurrency. The down payment of the third buyer 930 may be [advance +/- second buyer's profit (encryption currency)]*30/100.

The fourth buyer 940 may perform the contract using the advance payment and the cryptocurrency. The down payment of the fourth buyer 940 may be [advance payment] +/- [the third buyer's profit (encryption currency)]*30/100.

The final buyer 950 may pay the advance payment (10%) + unknown amount (90%) + the fourth buyer profit (encryption currency) and purchase the product.

According to an embodiment of the present invention, when a prepayment (for example, 10% of the product price) + profit (encryption currency) deposit is processed within a certain time (for example, 48 hours), the locked cryptocurrency is unlocked ( unlock) state. When unlocked, one final transaction may be completed.

Payment within a certain period of time (for example, 48 hours) (30% of the [prepaid price +/- profit] price) Encryption in the locked state when sold to a third party in an unprocessed state (assured cryptocurrency is locked) Currency can be attributed to the seller. When the seller node sells the product in a state in which the price is further lower than the purchase due to the decrease in the product price, the sale of the product may be performed by adding cryptocurrency to the state in which the product is dropped. In this case, the added cryptocurrency can remain locked until it passes to the buyer node.

If additional sales are made to a third party within a certain period of time (e.g. 48 hours), the final purchaser must deposit the advance payment (usually 10% of the commodity price) + profit (encryption currency) within a certain period of time again. The profit (encryption currency) is returned to the buyer node that was purchased, and no obligation is lost.

When the buyer node gives up the purchase, the cryptocurrency or deposit deposited by the buyer node may be attributed to the product planner node when the satisfaction of the final buyer of the product is greater than or equal to a threshold ratio (for example, 80%).

In this case, the product planner may resell the product. There may be restrictions on the sale as a condition that is better than the initial sale condition as the sale condition.

According to an embodiment of the present invention, a method for trading futures based on a blockchain is a step in which a shopping mall platform determines whether a product futures transaction of a product is possible based on a blockchain code, and a shopping mall platform provides a product based on a blockchain code. It may include the step of performing a commodity futures transaction for. The information about the commodity futures transaction is stored on a blockchain created in a blockchain network including a shopping mall node running a shopping mall platform, and the blockchain code is installed in the shopping mall node and includes contract information for operation on the blockchain. can do.

The availability of commodity futures trading is determined based on commodity price fluctuation information, commodity current price information, commodity volume information, and commodity price fluctuation information, commodity current price information and commodity volume information are collected by external nodes and transmitted to the blockchain network. It can be determined based on web scrolling information.

Commodity futures trading is performed based on a match between the seller node selling the product and the buyer node purchasing the product before the final buyer confirmation of the product, and the matching is performed with the first margin amount set by the seller node, which is the previous buyer node of the product. It is determined in consideration of the second margin amount set by the buyer node, and the first margin amount or the second margin amount may have a positive value or a negative value according to the price fluctuation of the product in cryptocurrency units.

The threshold percentage of the matching amount in which the matching has occurred is paid in cryptocurrency as a deposit, and the deposit can be set to a locked state for a certain period on the wallet delivered by the chain code.

10 is a conceptual diagram showing a member recommendation structure according to an embodiment of the present invention.

10, a structure for managing members for using a shopping mall is disclosed.

10, in order to use a shopping mall according to an embodiment of the present invention, member authentication must be performed. All users must perform member authentication. Access to a member's personal information is not possible without the member's permission.

When signing up for membership, the user must borrow a certain amount of stock on the basis of credit and “share interest” or “interest interest” at a certain rate. There are areas where the purpose of the borrowed stock is restricted, and it cannot be changed to other currencies, and consumption is not possible through shopping.

Information recorded on all blockchains can be managed by changing the encryption key for each channel and for each time zone. In addition, even if an abnormality occurs in a specific node due to an external attack, the abnormality node may be ignored and automatically restored to multiple nodes.

The external information disclosure of the member information may be provided only by member information agreed by the member in special cases such as shopping mall delivery, and the cryptocurrency used in the shopping mall may be operated only by an authenticated node. Requests from the outside can be built so that they are not directly accessible from the inside.

The result of the request cannot be accessed internally from outside the data. Subscription authentication may be performed by extracting mobile phone and fingerprint identification (physical information) information. Tracking member information is not possible. Members can track themselves, but others have no information to link member information. The hash method can be applied to the account number of personal information in two steps. You cannot track the data that created the hash from the hash. A hash value can be created from the data.

When a user registers as a member, it can receive investment from other existing subscriber nodes (recommended nodes) as new subscriber nodes.

The existing subscriber node may recommend the new subscriber node 1020 as the recommendation node 1000, and invest the cryptocurrency held in the new subscriber node 1020. The new subscriber node 1020, which has been invested in cryptocurrency by the existing subscriber node operating as the recommended node 1000, cannot convert the invested cryptocurrency into another cryptocurrency.

When investing, the existing subscriber node can invest the cryptocurrency held as the recommendation node 1000 at a certain rate to the new subscriber node 1020. Permissions on the blockchain-based shopping platform may vary depending on the quantity of cryptocurrency.

Profits generated in the blockchain-based shopping mall of the new subscriber node 1020 may be shared considering the ratio of cryptocurrency investment in the new subscriber node 1020. At this time, the profit sharing ratio is the maximum threshold percentage (regardless of the investment amount). For example, more than 30%) may be prohibited.

Invested cryptocurrency can be returned after a certain period (e.g., 12 months) to a critical percentage (e.g., 5%). Profits arising from shopping malls can be shared as a percentage of shares remaining after return of investment.

In addition, the invested cryptocurrency can be returned after 60 months from the critical rate (for example, 2%). The returned cryptocurrency can be incinerated without being attributed to the investor.

The user can classify the membership level based on the amount of cryptocurrency held. Products that can be sold/purchased only above a certain membership level may exist in the shopping mall platform. In addition, the product sales price can be discriminated and sold by member level/member credit. Creditworthiness can also be determined based on the amount of cryptocurrency held.

The price differentiation method can differentiate the ratio of recovering profits on the shopping mall platform. The price discrimination may be provided in such a way that discount coupons are given in real time in proportion to the amount of cryptocurrency held. For example, the discount price may be [product price-discount price per cryptocurrency * quantity of cryptocurrency held]. The range of discount prices [default 6%] can be picked up.

In addition, when selling the same product, the priority of the sale conclusion may be a member's grade. The higher the amount of cryptocurrency held, the more advantageous it may be in terms of the price of the purchased product on the shopping mall platform.

In the method of managing a member based on a blockchain according to an embodiment of the present invention, the shopping mall platform receives information about a new node recommended by the recommendation node, and the shopping mall platform receives a new node of the recommendation node based on the chain code. The method may include determining an investment cryptocurrency for the shopping mall and providing a profit cryptocurrency according to the investment cryptocurrency to the recommendation node by the shopping mall platform based on the chain code.

At this time, information about the recommended node, the new node, the cryptocurrency of the investment, and the cryptocurrency of the money is stored on the blockchain created in the blockchain network including the shopping mall node operating the shopping mall platform, and the chaincode is installed in the shopping mall node. It may include contract information for operation on the blockchain.

11 is a graph showing a profit distribution ratio according to an investment according to an embodiment of the present invention.

Referring to FIG. 11, reduction of investment of an existing subscriber node operating as a recommendation node over time and distribution of profits generated by a new subscriber node are disclosed.

The investment cryptocurrency invested by the recommendation node may be determined as a threshold ratio of the cryptocurrency held by the recommendation node. The investment cryptocurrency is first returned to the recommended node after the first threshold ratio is set after the first threshold period set based on the chaincode, and the revenue cryptocurrency can be reduced according to the threshold percentage.

In addition, the investment cryptocurrency is returned second after leaving the second threshold period to the second threshold ratio, and the second-return cryptocurrency can be incinerated without being attributed to the recommended node.

According to an embodiment of the present invention, three types of cryptocurrency can be used within the shopping mall platform.

The first cryptocurrency is a basic cryptocurrency unit used in the shopping mall platform, and can be bought and sold by individuals, individuals, or exchanges. As with other cryptocurrencies, you can transfer money in the form of payment.

The second cryptocurrency is a standard that reflects the contribution to the shopping mall platform. The second cryptocurrency and the first cryptocurrency can be exchanged at a set ratio (for example, 1:1).

The conversion between the second cryptocurrency and the first cryptocurrency can be sequentially exchanged at 1/16 for 16 periods at a set rate. In the second cryptocurrency, the roles of stock and currency can exist simultaneously. Currency works with payment and guarantee functions

Authority on the shopping mall platform may be granted in proportion to the quantity of the second cryptocurrency. Authorization is granted at a threshold ratio to the amount of the second cryptocurrency, and the size of the authorization is exhausted according to the behavior on the shopping mall platform and can be automatically charged in a critical time unit. Through this authorization, authority on the shopping mall platform and DDOS prevention are possible. The write, delete, and modify functions except for reading in the shopping mall platform may consume authority in the shopping mall and allow only limited operations according to the amount of the second cryptocurrency held in the shopping mall.

In addition, the second cryptocurrency may be distributed to a threshold ratio of profits generated on the shopping mall platform as a property of stocks. The second cryptocurrency is traded only within the shopping mall platform, and it may not be possible to transmit an exchange or p2p. As described above, the second cryptocurrency can be used as a margin of the seller according to the commodity futures transaction.

The third cryptocurrency can be utilized to provide profits generated on the shopping mall platform. Profits generated in the shopping mall platform may be provided as a third cryptocurrency after a specific period. The third cryptocurrency can be converted into a first cryptocurrency or a second cryptocurrency. Profits may be provided as a third cryptocurrency in consideration of the market price of the first cryptocurrency, the same day issue amount of the third cryptocurrency, and the like. As a third cryptocurrency, profits generated on the shopping mall platform may be provided, and a buffer function for unfair intervention in price fluctuation may be provided.

The proportion of rewards is adjusted, and the reduced rewards due to adjustments can be provided as a second cryptocurrency. The third cryptocurrency has no authority on the shopping mall platform and can be used when the cryptocurrency needs to be cashed.

12 is a conceptual diagram illustrating an issuance policy for cryptocurrency according to an embodiment of the present invention.

Referring to FIG. 12, a mining policy for a first cryptocurrency is disclosed.

The first cryptocurrency can be mined using a Bollinger band.

If the current price is outside the upper limit of the Bollinger Band, it is possible to mine the first cryptocurrency that satisfies (mining amount <2% of trading volume on the day) and (cumulative mining amount <1 year production capacity).

If the conditions are satisfied on the shopping mall platform, it may be possible to sell additional stakes. The sale may be performed for the purpose of increasing capital and compensating for development costs in order to compensate for a decrease in the price of the first cryptocurrency.

If it is within the upper limit of the Bollinger Band's center line, mining for the first cryptocurrency may be possible with (mining amount <2% of trading volume on the day) and (cumulative mining amount <1 year production value possible). In this case, only compensation-related mining is possible.

If it is within the range from the center line to the lower limit of the Bollinger band, mining for the first cryptocurrency may be possible with (mining amount <1% of trading volume on the day) and (cumulative mining amount <1 year production value possible). In this case, only compensation-related mining is possible.

If it is outside the lower limit of the Bollinger Band, mining is not possible and the shopping mall platform can compensate by buying the first cryptocurrency with its own cash as much as the compensation profit. In this case, mining to increase the issuance of the first cryptocurrency is stopped.

When the price of the first cryptocurrency in the market falls excessively irrespective of the sales and profits of the shopping mall platform, the market will exhibit the midnight function, but in this case, adjustment of the interest rate of the second cryptocurrency may be performed. have. At this time, the adjusted interest rate may be determined by a vote of the selected node as a vote based on the second cryptocurrency.
