A method of managing a product planned on the block chain based on the product planning information 250 will be described in detail later.

3 is a conceptual diagram illustrating a product management procedure based on a block chain according to an embodiment of the present invention.

3 discloses a method of setting a product management plan according to product planning information on a block chain. In particular, a method for establishing a contract with an initial purchaser 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 the block chain code installed in the shopping mall node (or block chain) 320, and the set product management plan is a block chain (or separately) It may be stored in a data storage unit (eg, key value store (KVS)) When the product management plan 360 recorded in a separate data storage unit 340 is stored, the block chain is stored in a separate data storage unit It is possible to store the hash value of the recorded data Hereinafter, in the embodiment of the present invention, the expression that information (or data) is uploaded on the block chain refers to the case where the hash value of information (or data) is uploaded on the block chain. It can be used in an 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 management information on a block chain according to product initial sales information, minimum order quantity information, product verification information, and product delivery information.

Based on the product initial sales information transmitted to the shopping mall node, the initial sales amount and the contract amount (for example, 10% of the initial sales amount) according to 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 block chain is uploaded, and the uploaded initial sales amount, contract amount, and contract amount deposit address may be disclosed to users using the shopping mall on the shopping mall platform. The purchaser node can remit the cryptocurrency corresponding to the contract amount to the public deposit address and deliver purchase agreement information, and a purchase contract can be established based on the remitted cryptocurrency and purchase agreement information. According to an embodiment of the present invention, the amount of cryptocurrency deposited as the 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 product initial price information and block chain 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 can select a stable coin or a non-stable coin to process the initial sales amount and contract amount.

In the case of stable coins, 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 sale price based on the block chain code may be continuously changed over a certain period of time. For example, price information of cryptocurrency is transmitted from an external exchange node at a set period (or block generation unit), and a newly updated initial sale price/contract amount may be determined based on the block chain code.

The set period may be changed according to the volatility of the cryptocurrency by determining the volatility of the cryptocurrency based on the block chain code. If the price volatility is determined based on the price information of the cryptocurrency delivered by the external exchange node and the price volatility is above the threshold, the set cycle of the initial purchase price may be changed based on the block chain 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 the purchaser node deposits cryptocurrency within a certain threshold block based on the change time of the cryptocurrency price, a processing method for cryptocurrency is disclosed.

The number of critical blocks determined based on the reference block, which is the point of change of the cryptocurrency price, 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 by considering the time of change of the contract amount and the processing speed of the block chain network, and in the case of cryptocurrency that corresponds to the contract amount before the change delivered within the critical block, It may be recognized that the contract amount has been deposited. If, due to an increase in the price of cryptocurrency, a refund for the difference proceeds to the buyer node, and in the case of a decrease in the price of cryptocurrency, an additional deposit may not be requested from the buyer for the change amount.

Alternatively, it may be separately set as a temporary suspension period of the contract on the threshold number of blocks before and after the threshold number of blocks based on the reference block, which is the time of change in the cryptocurrency price. In consideration of the block generation speed, contracts occurring on the threshold number of blocks before and after the threshold number of blocks may be treated as invalid.

In addition, according to an embodiment of the present invention, the changed initial purchase price information and the deposit address information are linked, and whether an amount corresponding to the changed initial purchase price is deposited in the corresponding deposit address in consideration of the deposit time is determined by the block chain code. 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 currency immediately or converted to cryptocurrency after a certain period of time. Alternatively, if the volatility is greater than a certain amount, it may be set based on the block chain code so that the cryptocurrency is directly converted to legal currency.

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

4 discloses a method for setting an initial sale period on a block chain.

Referring to FIG. 4 , by adding time information according to the setting of the initial sales period, a contract processed from a first block to an nth block, which is a contract start point, may be determined as contract completion. If the initial sale period is set to 7 days, in consideration of the physical time, transactions recorded in blocks created from 0:0:0:0 on the 0th to 0:0:0 on the 7th can be recognized as valid transactions.

Alternatively, 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 a separate actual network situation. After the product is released to the user, the creation time of the first block is set as the starting point, and the contract processed on the block created between the starting point and the initial sales period (for example, 7 days) is valid. can judge The shopping mall node 400 records the disclosure timing of the product information on the block, and the initial transaction block 410 and the generation time of the initial transaction block 410 may be determined based on the information on the recorded block. The contract processed on the block created during the initial sale period (eg, 7 days) is valid, and the first block created after the time point physically equivalent to 7 days from the creation time of the initial transaction block 410 Alternatively, the previous block of the first block generated after the time point corresponding to 7 days may be determined as the final transaction block 420 .

Alternatively, according to an embodiment of the present invention, the initial sales period may be determined based on the generation time of the actual data, not the block unit.

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

According to an embodiment of the present invention, the product planning node may set the initial product sales period by selecting one of the period setting options among the above period settings. Alternatively, according to an embodiment of the present invention, the shopping mall node may 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 start time of the initial sales period is selectively adjusted to a relatively later time (for example, after the product is released to the user, the creation time of the first generated block) and relatively time You can set the range. When the number of end-of-line contracts determines whether the product is finalized, or when the end-of-line contracts exceed the orderable quantity, the end of the initial sales period may be selectively adjusted relatively later.

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

In FIG. 5, a method for verifying a product based on product verification information on a block chain is disclosed.

Referring to FIG. 5 , 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 due date for each verification step and a checklist for each verification step may be set on the block chain.

At the verification stage due date, the product planner node 520 may submit the verification data 560 according to the verification stage checklist, and the determination of the product production fulfillment rate may be performed on the block chain. For example, if the product planner node 520 produces and sells 1000 planned product A, block verification data for verifying that it is possible to produce/sell 1000 planned product A within the time limit during verification step by step verification period You can upload it on the chain.

A separate verification node 540 is selected for verification of the product produced by the verification step, and verification by the verification node 540 may be performed. The verification node 540 is determined based on the existing activity details, the number of cryptocurrencies related to the shopping mall platform held by the verification node 540, and the like, and some verification nodes 540 may be randomly selected.

The first verification node group may include verification nodes randomly selected from among verification nodes exceeding a certain threshold level based on existing activity history information, information on the number of cryptocurrencies related to the shopping mall platform owned by the verification node, and the like. Existing activity history information includes information on whether the product has been verified correctly as a history of previous activity as a verification node, and the number of cryptocurrencies information refers to the amount of cryptocurrency to be used in the platform to be described later. there is. A node that can have a relatively good influence on the shopping mall platform through accurate judgment in consideration of the existing activity history information and the information on the number of cryptocurrencies may be selected as the first verification node group. The first verification node may be paid with cryptocurrency in return 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 select nodes except for the first verification node from among existing nodes, request to participate in the verification operation, and accept the request. Alternatively, the second verification node may be a node that pays a certain amount of cryptocurrency and requests to serve as a verification node. If the second verification node performs verification by the specified deadline, the transmitted encryption currency and additional encryption currency in return for verification may be returned. However, if verification is not performed by the specified deadline, the second verification node transmits the transmitted encryption You may not be able to get your money back.

The first verification result of the first verification node group and the second verification result of the second verification node group are transmitted on a block and may be determined collectively or individually to finally determine whether the verification step has been passed. For example, the verification results may be integrated by applying a first weight to the first verification result and applying a second weight to the second verification result based on the block chain code. Based on the integrated verification result, it may be determined whether the product has passed the verification procedure. For example, if the verification nodes greater than or equal to the first threshold ratio determine to pass, the verification procedure may be passed. When the verification node less than the first threshold ratio above the second threshold ratio determines to pass, re-verification may be performed by requesting additional data from the product planning node. If the verification nodes less than the second threshold ratio decide to pass, the verification procedure may be determined to fail.

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

The product planning information includes product initial sales information and product verification information, and the processing result information of product planning information and product planning information is to be stored on a block chain created in a block chain network including a shopping mall node operating a 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 block chain code, and the product sale information includes the contract amount according to the initial sale price and the deposit address of cryptocurrency information about the product, and a product purchase contract can be established by depositing 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 sale period, and the initial sale 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 product verification information and 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 includes a block It can be performed by a node selected as a verification node among nodes operating on the chain network.

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

The random selection mining node 620 may be a node capable of selectively performing a mining operation. The randomly selected mining node 620 may be selected according to a mining period, and may be a node capable of mining in a specific mining period. For example, the random selection mining node 620 may be a node in which a separate chaincode for enabling a mining operation to be performed only during a certain mining period is installed, and selectively 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 the n basic mining nodes 600 and the m random selection mining nodes 620 may be set differently depending on the processing speed of the required transaction. When the size of the generated transaction is in the range of a or more and b or less, n basic mining nodes 600 and m random selection mining nodes 620 are fully utilized to proceed with the mining procedure. In addition, when the size of the generated transaction is in the range of more than b and less than or equal to d, n' selected basic mining nodes among n basic mining nodes 600, m' selected random selections from m random selection mining nodes 620 The mining node 620 may be fully utilized to perform a mining procedure. In addition to this, when the size of the generated transaction is in the range of more than d and less than or equal to e, n' of the n' basic mining nodes 600, n'' selected basic mining nodes 600, m' randomly selected mining nodes 620 ) of m'' selected basic mining nodes 620 may be utilized to perform a 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 faster processing of transactions can be made.

A basic mining node 600 selected when changing from n to n' again n'' and a random selection mining node 620 selected when changing from m to m' again m'' Mining node 620 is a separate authority It can be determined by settings.

As described above, the initial purchaser node may sell the purchased product as the seller node, and the product sold by the seller node may be purchased by the purchaser node. The buyer node may again operate as a seller node and sell the purchased product.

Specifically, the purchaser node may operate as a seller node before a critical period based on the delivery date and sell the purchased product. The sales quantity of the seller node and the purchase quantity of the buyer node may be matched at the same time at a fixed time unit (eg, by an hour or by a day).

The price of the product may consist of a gift amount and an unpaid product amount, and [gift amount +/- cryptocurrency] can be presented when selling/buying the product. Matching priority may be determined by [price, cryptocurrency holding amount, asking price, request time]. At this time, the cryptocurrency may be cryptocurrency issued by the shopping mall node and usable within the shopping mall platform.

Not all products in the shopping mall may be subject to futures trading. 1) In the case of a product whose price fluctuates greatly depending on the period, 2) When the product price determined by the product planning node is significantly cheaper than the current product on the market, 3) When the quantity of the product is insufficient, etc. It can be registered as a gift product only if it is a condition.

The shopping mall node makes the following judgments based on the block code 1) whether the product has a large range of price fluctuations depending on the period, 2) whether the product price determined by the product planning node is significantly cheaper than the current product on the market, 3) It is possible to decide whether to trade futures for a product by determining whether the quantity of the product is insufficient.

8 is a conceptual diagram illustrating a method of determining whether a futures transaction is made based on a block code according to an embodiment of the present invention.

In Figure 8, whether the product is a product with large price fluctuations according to the period on the block chain (first condition), whether the product price determined by the product planning node is cheaper than the current product on the market by a threshold ratio or more (second condition), the product Disclosed is a method for determining whether or not the quantity of These conditions are expressed in terms of futures trading conditions.

Referring to FIG. 8 , based on the first, second, and third conditions on the block chain, the first determination node group 810 and the second 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 decision node groups may determine whether a commodity is futures tradable by determining a futures trading condition. Each group of decision nodes may be separately connected to an external node for determining each futures trading condition to receive data and generate a decision result based on the received data.

For example, the plurality of first decision nodes included in the first decision node group 810 includes the first external node group 815 in order to determine whether it is a product with a large price fluctuation range according to the period (a first condition). ) can be associated with In addition, the plurality of second decision nodes included in the second decision node group 820 includes a second external node group 825 and can be connected In addition, the plurality of third decision nodes included in the third decision node group 830 includes a third external node group 835 and 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 web scrolling is performed for data for the first condition, a server of a web site capable of acquiring more than a certain amount of 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.

It is possible to finally determine whether the first condition is satisfied by collecting the determination results of the plurality of determination node groups.

Thereafter, the first external node group 815 , the second external node group 825 , and the third external node group 835 are the external nodes included in the plurality of external node groups through the results collected from the threshold number of node groups. When the collection rate at which the same information is collected from a node is greater than or equal to a threshold ratio (eg, 70%), the corresponding external node may be included in only one external node group and excluded from other external node groups. External nodegroups can be updated according to continuous web scrolling.

By setting the external node in the above manner, determination for each of a plurality of conditions may be performed.

In addition, according to an embodiment of the present invention, data collection may be performed by assigning weights to some of the external nodes. Among external nodes, hierarchical status is given to nodes that provide data with high reliability, and data transmitted by a specific external node is set to a first layer external node, a second layer external node, and a third layer external node. It is possible to collect information by assigning a relatively high weight to the information collected by an external node of . Nodes for each layer can differentiate the nodes collected for each layer by additionally assigning layer-specific identifiers to data through separate data classification. In this case, the classification of the layers 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.

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

In addition, according to an embodiment of the present invention, the results collected to determine whether futures trading is possible may be post-processed and utilized to determine futures trading possibility for each product. For example, assuming that a TV is purchased, the range of possible price fluctuations of the TV, the discount rate of the currently provided TV price, the possibility of preparing the TV quantity, etc. should be considered based on the collected information. In this case, based on the data collected based on the external node, determination of the possible price fluctuation range for the model, the discount range, and the possibility of volume preparation may be performed.

For example, clustering can be performed on price information and price distribution can be determined based on clustering. Judgment can be performed based on price distribution within a cluster based on the proximity of price data included in the cluster. . The 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. A price distribution within a first threshold distance, a price distribution within a second threshold distance, and a price distribution within a third critical distance for each price data distribution within the cluster may be determined based on the cluster center. As the threshold distance including the price suggested by the product planning node increases and the data distribution value within the threshold distance decreases, the reliability may be lowered. The lower the reliability, the more relatively more verification nodes are extracted, and the judgment on the possibility of futures trading for each product can be performed.

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

9 discloses a futures trading method of a product subject to a futures transaction on a block chain.

Referring to FIG. 9 , resale of a product purchased through a shopping mall node is possible. However, it is possible to sell the commodity until before the expiration of the commodity futures (eg, 7 days before the supply date). At the expiration of the gift, the ultimate purchaser of the product may become the owner of the product. The margin for the sale price when selling the product can be set using cryptocurrency.

If the seller node and the buyer node match, the buyer node pays a deposit in cryptocurrency equal to a critical percentage (for example, 30%) of the [prepaid price +/- profit (cryptocurrency)] price, and the deposit is locked can be locked. Locked cryptocurrency cannot be transferred to other places.

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

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

The secondary purchaser 920 may perform a 30% contract with only cryptocurrency. The down payment of the secondary buyer 920 may be [advance payment +/- primary buyer profit (cryptocurrency)] * 30/100.

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

The fourth purchaser 940 may perform the contract using the advance payment and cryptocurrency. The down payment of the 4th purchaser 940 may be [advance payment] +/- [3rd purchaser's profit (cryptocurrency)]*30/100.

The final buyer 950 can purchase the product by paying the advance payment (10%) + the unknown amount (90%) + the 4th buyer's profit (cryptocurrency).

According to an embodiment of the present invention, if prepayment (eg, 10% of product price) + profit (encryption currency) is deposited within a certain period of time (eg, 48 hours), the encrypted currency in the locked state is unlocked ( unlock) state. If unlocked, one final transaction may be processed as completed.

Payment ([prepaid price +/- profit] 30% of the price) within a certain period of time (e.g., 48 hours) Unprocessed (guaranteed cryptocurrency is locked) when sold to a third party in locked state Money may be attributed to the seller. When the seller node sells a product in a state where the price has fallen further than the purchase due to a drop in the price of the product, the sale of the product may proceed in such a way that cryptocurrency is added to the falling state. In this case, the locked state can be maintained until the added cryptocurrency is transferred to the buyer node.

If additional sales are made to a third party within a certain period of time (for example, 48 hours), the last member who purchased the product must deposit an advance payment (usually 10% of the product price) + profit (cryptocurrency) within a certain period of time. Profit (cryptocurrency) returns to the buyer node who purchased it, and any obligations are eliminated.

When the purchaser node abandons the purchase, the cryptocurrency or deposit deposited by the purchaser node may be returned to the product planner node if the satisfaction of the final purchaser of the product is greater than or equal to a threshold ratio (eg, 80%).

In this case, the product planner may resell the product. As a sales condition, there may be restrictions on selling by setting better conditions than the initial sales conditions.

According to an embodiment of the present invention, a method for trading a gift based on a block chain includes the steps of: the shopping mall platform determining whether a product can be traded as a product gift based on the block chain code; and the shopping mall platform providing the product based on the block chain code. It may include the step of performing a commodity futures transaction for Information on commodity futures transactions is stored on a block chain created in a block chain network including a shopping mall node that operates a shopping mall platform, and the block chain code is installed in the shopping mall node and includes contract information for operation on the block chain can do.

Whether commodity futures can be traded is determined based on product price fluctuation information, product current price information, and product quantity information, and product price fluctuation information, product current price information, and product quantity information are collected by external nodes and transmitted over the blockchain network. It may be determined based on web scrolling information.

The commodity futures transaction is performed based on matching between the seller node that sells the product and the buyer node that purchases the product before final purchaser confirmation of the product, and the matching is performed with the first margin amount set by the seller node, which is the previous purchaser node of the product. It is determined in consideration of the second margin amount set by the purchaser node, and the first margin amount or the second margin amount may have a positive or negative value according to a price change of the product in units of cryptocurrency.

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

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

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

Referring to FIG. 10 , member authentication must be performed in order to use the shopping mall according to the embodiment of the present invention. All users must perform member authentication. Access to the member's personal information is impossible without the member's permission.

When a user joins as a member, the user is required to borrow a certain amount of stock from the shopping mall platform, borrow a certain amount of stock based on credit rating, and pay a certain amount of interest or share profits at a certain rate. Borrowed stocks are subject to restrictions on the purpose of use, cannot be exchanged for other currencies, and cannot be consumed for shopping.

Information recorded on all blockchains can be managed by changing the encryption key for each channel and time zone. Also, even when a specific node malfunctions due to an external attack, the abnormal node can be ignored and automatically restored as multiple nodes.

The disclosure of external information of member information can only be provided with member information agreed by the member only in special cases such as shopping mall delivery, and the cryptocurrency used in the shopping mall can be operated only by authenticated nodes. Requests from the outside can be structured so that they can't directly access the inside.

The request result is internally driven and cannot be accessed from outside the data. Subscription authentication may be performed by extracting mobile phone and fingerprint recognition (body information) information. It is not possible to track member information. Members can track themselves, but there is no information that can link other members' information. The account number of the personal information can be applied in two steps of the hash method. You cannot trace the data that created the hash from the hash. A hash value can be created from the data.

When a user joins a membership, an investment can be received from another existing subscriber node (recommended node) as a new subscriber node.

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

At the time of investment, the existing subscriber node may invest the cryptocurrency held as the recommendation node 1000 in the new subscriber node 1020 at a certain rate. Permissions on the blockchain-based shopping platform may vary depending on the amount of cryptocurrency.

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

The invested cryptocurrency can be returned after a certain period (eg, 12 months), leaving up to a threshold percentage (eg, 5%). Profits generated in the shopping mall may be shared as a percentage of the remaining stock after the return of the investment.

In addition, the invested cryptocurrency can be returned after 60 months, leaving up to a critical rate (eg, 2%). The returned cryptocurrency can be burned without being attributed to the investor.

Users can classify membership levels based on the amount of cryptocurrency they hold. There may exist products that can be sold/purchased only with a certain membership level or higher within the shopping mall platform. In addition to this, product sales prices may be differentiated according to membership level/member credit rating. Creditworthiness can also be determined based on the amount of cryptocurrency held.

The price differentiation method can differentiate the rate of recovering profits from the shopping mall platform. Price discrimination can be provided in 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]. A range of discount prices [default 6%] can be picked up.

In addition, when selling the same product, the priority of signing a sale 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 products purchased on the shopping mall platform.

A block chain-based member management method according to an embodiment of the present invention comprises the steps of: a shopping mall platform receiving information on a new node recommended by a recommendation node, and the shopping mall platform to a new node of a recommendation node based on a chain code It may include the steps of determining an investment cryptocurrency for investment and providing, by the shopping mall platform, a profit cryptocurrency according to the investment cryptocurrency to the recommendation node based on the chain code.

At this time, information on the recommendation node, new node, investment cryptocurrency, and profit cryptocurrency is stored on the blockchain created in the blockchain network including the shopping mall node that operates the shopping mall platform, and the chain code 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 , the return of investment of an existing subscriber node operating as a recommendation node over time and distribution of profits generated by the new subscriber node are disclosed.

The investment cryptocurrency invested by the recommender node may be determined by a threshold ratio of the cryptocurrency held by the recommender node. The investment cryptocurrency is returned to the recommendation node after the first threshold period set based on the chain code, leaving up to the first threshold ratio, and the profit cryptocurrency may be reduced according to the threshold percentage.

In addition, the investment cryptocurrency is returned secondarily after the second threshold period, leaving up to the second threshold ratio, and the secondary returned cryptocurrency may be burned without belonging to the recommendation node.

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

The first cryptocurrency is a basic cryptocurrency unit used within the shopping mall platform, and can be bought and sold by individuals or exchanges. It can process remittance as a form of payment like other cryptocurrencies.

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

The conversion of the second cryptocurrency and the first cryptocurrency can be sequentially exchanged at 1/16 for 16 periods at a set rate. The second cryptocurrency can serve as a stock and a currency at the same time. Currencies work as payment and guarantee functions

Authority on the shopping mall platform may be granted in proportion to the quantity of the second cryptocurrency. Authorization is given to the holding amount of the second cryptocurrency at a threshold ratio size, and the size of this authority is exhausted according to actions on the shopping mall platform, and can be automatically recharged in a threshold time unit. Through this authorization, it is possible to prevent authorization and DDOS on the shopping mall platform. Write, delete, and edit functions other than read in the shopping mall platform consume authority in the shopping mall and allow only limited operations in the shopping mall according to the holding amount of the second cryptocurrency.

In addition, the second cryptocurrency may be distributed with respect to a threshold ratio of profits generated on the shopping mall platform due to the nature of stocks. The second cryptocurrency is traded only within the shopping mall platform, and may not be able to be transmitted through an exchange or p2p. As described above, the second cryptocurrency may be used as a margin of the seller according to the commodity futures transaction.

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

The rate of compensation is adjusted, and the compensation reduced due to the adjustment may be provided as a second cryptocurrency. The third cryptocurrency has no authority on the shopping mall platform and can be used when cashing of cryptocurrency is required.

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 may be mined using the Bollinger Bands.

If the current price is out of the upper limit of the Bollinger band, the first cryptocurrency that satisfies (mining volume < 2% of daily trading volume) and (cumulative mining volume < 1 year production potential) can be mined.

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

If it is within the upper limit range from the center line of the Bollinger Band, mining for the first cryptocurrency may be possible with (mining amount < 2% of daily trading volume) and (cumulative mining amount < possible production value for one year). In this case, only reward-related mining is possible.

If it is within the lower limit range from the center line of the Bollinger Band, mining for the first cryptocurrency may be possible with (mining volume < 1% of daily trading volume) and (accumulated mining volume < 1 year possible production value). In this case, only reward-related mining is possible.

If it is outside the lower limit of the Bollinger Band, mining is impossible and the shopping mall platform can compensate by purchasing the first cryptocurrency with its own cash as much as the compensation profit. In this case, mining that increases the issuance of the first cryptocurrency is stopped.

If the price of the first cryptocurrency in the market causes an excessive drop regardless of the sales and profits of the shopping mall platform, the self-cleaning function will be exerted in the market, but in this case, adjustments to the interest rate of the second cryptocurrency may be performed. there is. At this time, the adjusted interest rate may be determined by a vote of a node selected as a vote based on the second cryptocurrency.
