Description

METHOD FOR PROVIDING BLOCK CHAIN BASED PRIZE LOTTERY SERVICE BY DEADLINE ANTICIPATION PER PRIZE}

The present invention relates to a method for providing a sweepstakes service by predicting the entry deadline for each blockchain based prizes, and issuing a prize entry ticket corresponding to a shopping mall purchase and receiving the predicted prize deadline when recruiting applicants, thereby predicting the closest data. Provide a way to select the winners who have submitted their entries.

In general, consumers tend to be more interested in interactive communication such as sweepstakes and events than unilateral communication such as advertising. The Internet environment is a good condition for two-way communication between businesses and consumers, and prizes, including games, quizzes, and gambles, in which consumers participate online, are notable. At this time, the consumer is interested in not only the contents of the prize but also the possibility of winning. According to the hedging theory, consumers tend to prefer a 100% safe alternative without uncertainty even if the expected value is smaller. According to the Loss Avoidance Theory, a giveaway with a 100% chance of worth 10,000 won can be more attractive than a giveaway that offers a value of 50,000 won with a 30% chance of winning. The mathematical expected value is interesting because the latter is worth 5,000 won more than the former.

At this time, a prize lottery method using a random index that is difficult to predict, such as a composite stock index, was researched and disclosed. In this regard, Korean Patent Publication No. 2009-0118300 (published on November 18, 2009), which is a prior art, issues information on prizes. After receiving a gift voucher service from a database, customer terminal, giveaway service client, and giveaway service requester, issue a voucher, store it in the database, receive a unique number from the customer terminal, and save it in the database. In this case, it is composed of a prize server that receives a random index from the operator terminal and determines the winning number, and a prize issuing unit for which the prize server issues a prize right, a reference number calculating unit for determining a reference number for drawing from a unique number, A reference value deciding part for deciding a reference value in a random index, and a reference number It discloses a configuration including a winning determination by comparing the determined reference, the winning numbers.

However, the above-mentioned prize draw method promotes meandering by using a random index, and ignores loss avoidance needs of consumers through the random index. As a result, consumers who already know that they won't win the event won't be acting on the event itself, and the chances of being randomly selected for the opportunity cost of selling their personal information while applying to the event are the lottery. We have already recognized that it is similar to the probability of winning. As a result, not only the number of applicants but also the marketing effect of the prize event is continuously decreasing.

An embodiment of the present invention is to issue and send a sweepstakes ticket to a user who has made a purchase through a shopping mall, and to apply for a sweepstakes event with a sweepstakes ticket, revealing the conditions for the sweepstakes and satisfying the sweepstakes closing conditions. By selecting the closest predicted user as the winner, it eliminates the meandering and strategically adjusts the probability to induce optimal interest, immersion and goodwill to the consumer, and the increased sales of the mall are holders with unique coins. It allocates to the user based on the amount of holding and the period of retention, and provides the type of currency to be distributed as a Stable coin so that the preset exchange can be changed to a nominal currency or another type of cryptocurrency, and each terminal is blockchain. By setting up each node within the network, cryptocurrency transactions can be fulfilled by smart contracts. Which can provide a block-based chain prizes by the application deadline sweepstakes service delivery through the forecast. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention, when purchasing a product in a predetermined shopping mall in at least one user terminal, at least one prize entry ticket corresponding to a predetermined percentage of the product sale price Paying to one user terminal, transmitting a sweepstake event including a prize type to at least one user terminal owning a sweepstakes ticket, and when a prize type is selected from at least one user terminal owning a sweepstakes prize, Requesting prediction data for predicting a closing time; when receiving prediction data from at least one user terminal selected with a prize type, mapping and storing the prediction data and the prize type with at least one user terminal; and preset prizes Set the time to meet the deadline as the prize closing time, Selecting a user terminal that has submitted prediction data closest to the set prize closing time, selecting a winner, and transmitting a winning message to the user terminal of the user who is the winner.

According to any one of the problem solving means of the present invention described above, it is possible to issue and send a sweepstakes ticket to a user who made a purchase through a shopping mall, and to enter the sweepstakes event with a sweepstakes ticket, to disclose the conditions for closing the sweepstakes and to close the sweepstakes. By selecting the user who most closely predicts the time when the condition is satisfied, the winner is eliminated the meandering and strategically adjusted the probability to induce the optimum interest, immersion and favor to the consumer, and increase the sales of the shopping mall Is distributed to holders of unique coins based on the amount of holdings and the holding period, and the type of currency to be distributed is provided as a Stable coin so that it can be changed from a preset exchange to a nominal currency or another type of cryptocurrency. Smart transaction by setting each terminal as each node in the blockchain By allowing the contract to be implemented by the contract, the emotional quality of the customer can be enhanced.

Referring to FIG. 2, when the purchaser 310 purchases a product in a predetermined shopping mall in the at least one user terminal 100, the payer 310 receives a prize entry ticket corresponding to a preset percentage of the product sale price. You can pay with (100). For example, prizes can be paid up to 15% of the total amount of the purchase. Here, if the value of one prize entry ticket is the same, the higher the purchase amount of the prize, the greater the number of prize entry tickets can be paid. Alternatively, if the value of one prize entry ticket is different, the prize entry ticket with a different value corresponding to the purchase amount of goods may be allocated. It may be variously configured according to the embodiment and is not limited to any one embodiment.

The transmitter 320 may transmit a prize event including a prize type to at least one user terminal 100 that owns a prize entry. At this time, the sweepstakes event is not a random draw, but a sweepstakes condition is set, and a user who selects or closes the user who most closely matches or predicts a point at which the sweepstakes conditions are satisfied is selected as a winner. Of course, this does not preclude the random selection of winners from the sweepstakes event. For example, assuming that the prize closing condition is 100 applicants, the time at which 100 people are reached cannot be predicted in advance. Or, assuming the closing condition is time, the system knows the time internally but the applicant cannot know the deadline. Therefore, the transmitter 320 may inform and match the approximate time range to the applicant. Alternatively, the prize closing conditions may also be set to the number of participants participating in the prize, in which case the prize closing time must be fixed. In such a case, the winner is not selected as the winner who meets or predicts the closest time to satisfy the prize closing condition, but the winner who selects or predicts the number of winners based on the preset and fixed prize closing time. Done. Of course, it will be apparent that the winners may be selected by various methods in addition to the above-described method, and in the case where a plurality of tie scores are generated, all of them may be treated as winners.

When the request unit 330 receives a selection of a prize type from at least one user terminal 100 that owns a prize entry ticket, the requester 330 may request prediction data for predicting a prize closing time. Here, the prize type and the prize event may be selected by the user terminal 100, and a value predicted of the prize closing time may be transmitted to the requester 330.

When the storage unit 340 receives the prediction data from the at least one user terminal 100 having selected the prize type, the storage 340 may map and store the prediction data and the prize type with the at least one user terminal 100. Here, when there are a plurality of prize events, the user must select a prize type, and the closing conditions may be different for each prize event, and the closing time for meeting different closing conditions may also be different, so the event type, prize type, and closing The prediction time is stored for each user who applied, so that the winner can be used later.

The selecting unit 350 may set a time that satisfies a preset prize closing condition as a prize closing time, select a user terminal 100 that has submitted prediction data closest to the set prize closing time, and select the winner. have. In this case, when there are a plurality of user terminals 100 which have submitted the closest prediction data, the plurality of user terminals 100 may be selected and selected as a winner. For example, suppose the prize deadline was 2:40 on February 2, 2020, 100 applicants submitted, and the closest forecast data was 2 minutes out of 100 predicted data. The error range of minutes is selected as the closest prediction data. This is not absolute, but fixed because it is relative and is determined after all applicants have entered the deadline. The two-minute error range in this event is five minutes in the next event, even though the two-minute error range was the nearest prediction. The range may be the nearest prediction, or the 10-second error range may be the nearest prediction or may be different.

The winning part 360 may transmit a winning message to the user terminal 100 of the user who is the winner. Accordingly, the user terminal 100 may transmit data, such as an address or a delivery destination, to receive the prize, to the winning part 360. If the prize entry is perishable, the prize entry of the applicant who does not win may be destroyed by the quantity or type used. Here, if the prize entry is non-destructive, the type and quantity of the prize entry used in the entry may be returned to the account of the user terminal 100 again.

When the purchaser 370 purchases a product in a shopping mall set by the at least one user terminal 100 in the payer 310, the purchaser 370 may receive a prize entry ticket corresponding to a preset percentage of the product sale price of the at least one user terminal ( After payment to 100), at least one user terminal 100 may set the shopping mall stable coin at a predetermined exchange. Here, the stable coin may be a token in the form of a STO (Stable Token Offering) based Stable coin. In this case, the stable coin is a virtual currency that guarantees price stability by interworking with an existing currency or real asset, and the stable coin of the present invention may be in the form of any one or combination of at least one of the types described below. The types of Stable Coins can be classified into Fiat-Collateralized Stablecoin, Crypto-Collateralized Stablecoin, and Non-Collateralized Stablecoin, but are not limited thereto. Stable coins often require a centralized operating institution to issue stable coins and guarantee their value, and three stable coins can apply different principles to keep money at a constant price.

First, we explain Fiat-Collateralized Stablecoin. Statutory monetary security means that a particular company or agency deposits statutory money in your account as collateral and issues tokens corresponding to that amount. In many cases, they issue tokens that can be exchanged at the rate of 1 USD. Trading with Stable Coin will help both buyers and sellers to minimize damages caused by price fluctuations, even if the price of Stable Coin fluctuates on the exchange, It is thanks to the recognition.

Second is Crypto-Collateralized Stablecoin. At this time, while there is a method of making the fiat money as a collateral basis for the price stability of the virtual currency, there is also a method of making the value of the virtual currency as collateral. Cryptocurrency collateral also secures stability by maintaining a constant exchange rate of stable coins based on fiat currency (dollar). But the fundamental reason for this is the existence of collateral. In other words, it is a form of lending a stable coin with stable value to a consumer by treating a cryptocurrency such as Ethereum as a collateral currency. First, when a stable coin consumer places a secured cryptocurrency, such as Ethereum, on the account, he / she will issue a loan with a stable coin based on the collateral value. Thereafter, the consumer must return the same amount of stable coins within the loan period, in which case the collateral is returned and the account is settled.

The third is a non-collateralized stablecoin. Unlike the fiat-collateralized and crypto-secured Stable Coins described above, unsecured Stable Coins have no collateral. Instead, it is a price stable cryptocurrency that maintains the price of the coin by controlling the distribution of coins only by the algorithm or the system as the price of the coin, that is, the exchange rate with the peged asset changes. At this time, the factor influencing the price fluctuation of the coin can be seen as the fluctuation of people's demand. Cryptocurrency with constant supply fluctuates in price depending on people's demand, while unsecured Stable Coin can maintain the target price by adjusting the distribution of coins to the size of demand.

When the payment unit 310 purchases a product in a predetermined shopping mall in the at least one user terminal 100 in the payment unit 310, the substitute unit 380 receives a prize entry ticket corresponding to a predetermined percentage of the product sale price. After the payment to 100, if at least one user terminal 100 in the pre-set shopping mall in operation, the advertising costs for advertising the shopping mall by the selection of the at least one user terminal 100 Can be replaced with a prize entry.

Table 1 summarizes the available functions and rights of the user terminal 100, the unique coin holder terminal 400, and the stable coin holder terminal 500.

The prize lottery service providing server 300 may be a server that provides a page of a predetermined shopping mall and a server that issues a shopping mall unique coin that receives a profit corresponding to a predetermined percentage of the sales of the predetermined shopping mall. Here, the unique coin is a virtual currency (including cryptocurrency) issued by the prize lottery service providing server 300 itself, and when using a shopping mall, a unique coin may be used along with a nominal currency. In addition, the prize lottery service providing server 300 is a server for issuing a shopping mall stable coin (Stable coin) that can be traded on a predetermined exchange, the revenue distribution of the mall unique coin may be paid to the shopping mall stable coin. In this case, the unique coin holder terminal 400 having the shopping mall unique coin may receive a profit corresponding to a predetermined percentage in accordance with the amount of holding and the holding period of the shopping mall unique coin on a daily basis.

In addition, at least one user terminal 100 may correspond to at least one node forming a blockchain network, and the blockchain may be formed of a public blockchain or a private blockchain. In this case, the prize lottery service providing server 300 may list an original coin or stable coin (IEO: Initial Exchange Offering). At this time, in order to explain IEO, the concept of ICO will be compared. In the blockchain ecosystem, funds are raised through initial coin offering (ICO). In general, the process of an ICO consists of white paper publication, promotion, white paper verification, KYC (know your customer) certification, and sales. The sale is a crowd sale to the public through a private sale to a small number of early investors, an institution such as a crypto fund or a pre-sale to early adopters. Proceed. Since the ICO is banned by regulation, there is also an Initial Exchange Offering (IOE) method that only proceeds to private sale and is listed directly on the cryptocurrency exchange. There are reverse ICOs where existing companies conduct ICOs, and there are DAICOs that conduct ICOs with voting through the Decentralized Autonomous Organization (DAO).

In this case, ICO is a direct investment method such as sending Ethereum directly to a cryptocurrency project, whereas IEO is an indirect investment method of an investor in a cryptocurrency project through an exchange. Since most cryptocurrency projects are global projects, no matter how good the project contents and future prospects are, it is difficult for investors to collect the information of foreign cryptocurrency issuers. Therefore, direct investment through ICO is difficult. In addition, to participate in the ICO, it is necessary to sign up for each project every investment, and to worry about the leakage of personal information, such as sending a passport photo to comply with the customer verification obligation called KYC / AML and anti-money laundering. On the other hand, IEO can invest with one-time authentication of personal information on exchanges, reliable exchanges can make investments, and information on cryptocurrency projects can be easily obtained. In this case, the cost of marketing or funding can be reduced, and the focus can only be on technology development, and IEO can save exchange listing fees because the invested project is directly listed on the exchange.

Here, in order to better understand IEO, it is necessary to understand the stock exchange in charge of IPO. The Stock Exchange is primarily responsible for i) the ability for multiple people to buy stocks issued by a company, and ii) the ability to trade stocks acquired. On the other hand, the goal of blockchain and cryptocurrency is to solve problems of centralized human trust-based systems such as stock exchanges. In the technical trust-based system through blockchain technology, no one can manipulate transaction details centrally, so the transparency and security of transactions are technically secured. As such, the person who invests the funds of the investor becomes the intrinsic coin holder terminal 400, and the intrinsic coin holder terminal 400 can receive profits for the funds every sales generation cycle or in real time.
