Blockchain-based Gift Certificate Token Distribution System {SYSTEM FOR DISTRIBUTING GIFT CERTIFICATE TOKEN BASED ON BLOCKCHAIN}

The present invention relates to a blockchain-based voucher token distribution system, to issue a voucher based on the token stored in the blockchain ledger and to improve the reliability of transactions by interworking with the reputation system.

Since blockchain-based Bitcoin was developed by Satoshi Nakamoto in 2009, numerous cryptocurrencies have been created that enable decentralized transactions without central institutions such as banks. Currently, blockchain technology is becoming more common and applied in various industries, such as alternatives to new financial services such as convenient international remittances, or as decentralized data storage and as a platform for decentralized applications.

Many ideas have also been attempted to store tokens of various assets on such blockchains and make them tradeable. The present invention is also in this context.

Gift certificates are similar to coupons that provide discounts on goods or goods that are in use worldwide, and, under national law, bearer securities that can receive certain goods and services or goods and services for a specified amount from the providers specified in that recommendation. This can be called. In Korea, the portion of paper gift certificates issued by the Korea Mint Corporation by paying stamp duty is overwhelming, but the proportion of digital gift certificates such as mobile is gradually increasing.

However, since the mobile platform is still too high for small and medium-sized businesses to issue mobile vouchers, and the distributed mobile vouchers manage the information on the issuer's server, the secondary transaction where the buyer transfers unnecessary vouchers to third parties is quite inconvenient. Coupons must use a used transaction service.

On the other hand, blockchain has made a lot of technological advances, but no successful cases of linking with real assets have yet been heard. The method of storing the rights of various assets on the blockchain should consider the case as many kinds of assets and the cryptocurrency that is issued is difficult to find the link with the real assets. This is the most widely used reality.

Gift certificates can be directly priced by the issuer and are intimately connected with real assets by promising to provide goods or services. Therefore, an attempt to issue token-based gift certificates, store them on the blockchain, and trade them with cryptocurrency will be very meaningful.

An embodiment of the present invention implements a blockchain server and a voucher token distribution system that can store various voucher information and issue tokens, so that anyone can easily issue vouchers and distribute vouchers without an intermediary, and thus autonomously issue and distribute vouchers. It aims to implement an ecosystem.

Referring to FIG. 3, when the gift certificate token issuing platform unit 220 receives an issue request for issuing a gift certificate token from the issuer terminal 310, the issuer of the gift certificate token is issued from the issuer terminal 310 through the communication unit 210. The blockchain server 100 receives from the gift certificate token distribution system 200 by receiving the gift certificate token issuance information regarding the amount of the gift certificate token and the contract of the gift certificate token and transmitting the gift certificate token issuance information to the blockchain server 100. Generate a block including the gift voucher token issuance information based on the signed gift voucher token issuance information and the signature information based on the key of the wallet client 311 received from the issuer terminal 310, and store the block in the blockchain ledger and issue the voucher token. Process.

When the blockchain server 100 receives a voucher issuing request including voucher token issuing information, the blockchain server 100 receives signature information from the wallet client 311 of the issuer terminal 310 for the issuer's first coin and requests for issuing the voucher token. The amount of the first coin to be withdrawn from the issuer, the portion of the withdrawn first coin is recorded in the blockchain ledger as the deposit amount of the corresponding gift certificate token, and the rest of the withdrawn first coin is the fee for issuing the gift certificate token. As a result, the operator of the blockchain server 100 records the information in the blockchain ledger.

According to an embodiment of the present invention, a gift certificate token issued on a token basis and stored in the blockchain ledger includes an identification ID and contract matters (for example, goods, services, and amounts), issuer, owner, issue price, and expiration date. (For example, the expiration date of a gift certificate, etc.). Here, even if there are a plurality of gift certificates having the same attribute except for the identification ID, they are stored and managed independently, and the contract items are provided with a specific item or a specific service, or the amount is displayed like a prepaid card. May exist in the form of an image. However, if the contract can be described in detail, the form is not limited. Furthermore, the issuance price of the gift certificate token is determined by the first coin, and the gift certificate token can be transferred to a third party through an interpersonal transaction and can expire by setting an expiration date.

After receiving the purchase request, the blockchain server 100 receives signature information from the wallet client 321 for the first coin of the buyer and receives the first coin of the amount required for the purchase of the issued gift certificate token. The operator of the blockchain server 100 withdraws and transfers some of the withdrawn first coins to the issuer as the sale amount of the corresponding gift certificate token, and transfers the rest of the withdrawn first coins as a fee for trading the corresponding gift certificate token. Record it on the blockchain ledger for acquisition.

According to an embodiment of the present invention, the gift certificate token distribution system 200 may issue a gift certificate token and retrieve the issued gift certificate token. When a user logged in through a key stored in the issuer's wallet client 311 or a registered member ID and password issues a voucher token, the voucher token is issued by transferring information input from the issuer to the blockchain server 100. The buyer can retrieve the issued voucher token.

5 is an exemplary diagram representing the details recorded in the blockchain ledger when issuing and purchasing a gift certificate token in the gift certificate token distribution system according to an embodiment of the present invention.

Referring to FIG. 5, it can be seen that in the trade 10001, Hong Gil-dong and the forestry industry have 2,000 coins in the wallet client for each first coin [trade 10001].

After that, if Hong Gil-dong issues two gift certificate tokens corresponding to one cup of coffee with the issue price of 100 coins, the identification ID of the gift certificate tokens is assigned to the blockchain ledger as x2de21ua and 4e1xft2a, respectively, and the contract details are one cup of coffee and the issuer Hong Gil-dong, owner Hong-gil-dong, and issuance price 100 coins. At the same time, 205 coins required for issuance of gift certificate tokens are withdrawn from Hong Gil-dong's wallet client of Hong Gil-dong's first coin, and some of the withdrawn 205 coins are recorded in the blockchain ledger as 200 coins of the corresponding gift certificate tokens. Finally, the remaining 205 coins are recorded in the blockchain ledger to acquire 5 coins from the blockchain server owner A who processed the blockchain transaction as a fee for issuing a gift certificate token [transaction 10002].

Then, when Lim purchases a gift voucher token with an ID of x2de21ua, the owner of the gift voucher token of the identification ID x2de21ua recorded in the blockchain ledger is changed from Hong Gil-dong to forestry industry and 100 coins required to purchase the voucher token are Withdrawal from the forestry industry, 95 coins, which are part of the sales amount of the gift certificate tokens, are transferred to Hong Gil-dong, and the remaining 5 coins of the sales amount of the gift certificate tokens are acquired by the operator of the blockchain server as a fee for the transaction of the gift certificate tokens. Are recorded in the blockchain ledger.

According to one embodiment of the invention, the blockchain server 100 from any one or both of the transferee terminal 330 of the transferee holding the gift certificate token and the transferee terminal 340 of the transferee to purchase the gift certificate token Upon receiving a transaction request for trading the gift voucher token, the signature information based on the key of the wallet client 331 installed in the assignee terminal 330 and the signature information based on the key of the wallet client 341 installed in the assignee terminal 340. Based on either or both, the owner of the gift voucher token is recorded in the blockchain ledger to be changed from assignor to assignee.

When the blockchain server 100 receives a transaction request, the blockchain server 100 receives signature information from the wallet client 341 for the first coin of the assignee, withdraws the first coin of the amount required for the transaction of the gift certificate token, and withdraws the Transfer some of the first coins to the transferor with the transaction amount of the corresponding gift certificate token, and blockchain ledger so that the operator of the blockchain server 100 acquires the remaining one of the withdrawn coins as a fee for the transaction of the gift certificate token. To record.

Referring to FIG. 6, when looking at transaction 10004, Hong Gil-dong is 1,890 coins (deposit 200 coins), Lim Kyung-in is 1,900 coins, Kim Young-hee is 1,000 coins, Blockchain Server Owner A is 5 coins, Blockchain Server Owner B is the first of 5 coins. You can confirm that you own the coin and own the gift certificate token with identification ID x2de21ua.

Subsequently, if Kim Young-hee receives the gift certificate token x2de21ua from Lim Kyung-up, the owner of the gift voucher token of identification ID x2de21ua is changed from Im-kyung to Kim Young-hee and 100 coins required to transfer the gift certificate token are withdrawn from Kim Young-hee. 95 coins, which are part of the token's sale amount, are transferred to the forestry industry, and the remaining 5 coins, which are the sale amount of the gift certificate token, are recorded in the blockchain ledger to be acquired by the owner C of the blockchain server as a fee for the transaction of the gift certificate token. [Transaction 10005].

7 is an exemplary diagram representing the details recorded in the blockchain ledger when the gift certificate token is converted to the second coin in the gift certificate token distribution system according to an embodiment of the present invention.

According to an embodiment of the present disclosure, when the blockchain server 100 receives a confirmation of the use of a gift certificate token for an issuer from a holder terminal (not shown) of a holder holding a gift certificate token, the blockchain server 100 may include a first deposit corresponding to a deposit amount. Transfer the coin to the issuer, convert the voucher token to the second coin of the set amount and pay it to the issuer and record the voucher token in the blockchain ledger to extinguish it.

Referring to FIG. 7, when looking at transaction 10006, Hong Gil-dong is 1,890 coins (deposit 200 coins), Lim Kyung-in is 1,995 coins, Kim Young-hee is 900 coins, blockchain server owner A is 5 coins, blockchain server owner B is 5 coins, blockchain server Owner C holds the first coin of 5 coins, and the gift certificate token with the identification ID x2de21ua is owned by Kim Young-hee [Transaction 10006].

Afterwards, upon receipt of the confirmation of the use of the gift voucher token x2de21ua owned by Kim Young-hee, the 100 coins deposited by the voucher token x2de21ua in Hong Gil-dong's deposit are converted to the second coin and paid to Hong Gil-dong, and the blockchain ledger is destroyed to destroy the voucher token. The recording blockchain server owner D records 5 coins in the blockchain ledger [transaction 10007].

According to an embodiment of the present invention, the nodes of the blockchain server 100 operate a consensus algorithm based on a proof of stake (POS) method, and a wallet for a second coin of a holder holding a second coin. The client may access the gift voucher token issuing system and convert the second coin into a stake used in the consensus algorithm to operate as a blockchain server node under the blockchain protocol. In other words, the user terminal 300 may also be any blockchain node that complies with the blockchain protocol as the blockchain server 100.

According to one embodiment of the present invention, the gift voucher token distribution system 200 issuing price of the gift voucher token from the holder terminal holding the voucher token to the issuer terminal of the voucher token based on the use confirmation of the voucher token for the issuer. The second coin is provided at a preset ratio of. In other words, the second coin is a coin that is paid to the issuer of the gift certificate token when the gift certificate token issued by the token issuer is used.

In the event that the gift voucher token issued by the issuer of the gift voucher token is confirmed for use, the second coin paid as a reward to the issuer of the voucher token is the only means to acquire the second coin on the system 200. The second coin can be traded between users similarly to the first coin.

According to an embodiment of the present invention, the gift certificate token distribution system 200 may convert the second coin into a stake or convert the stake into a second coin, and the user terminal according to the amount of stake held by the blockchain server 100. Transactions issued within the gift certificate token distribution system 200 including a token issuance request of 300 and a token purchase request of the user terminal 300 may be differentially provided. For example, the gift voucher token distribution system 200 may include a transaction in the gift voucher token distribution system including a request for issuing a gift voucher token and a request to purchase a voucher token according to the amount of shares held by the blockchain server 100. Can be provided differentially. In other words, it is determined that the blockchain server 100 having a relatively large amount of stake is more reliable than the blockchain server having a small amount of stake, and the request of the user terminal 300 requests the blockchain server 100 having a large amount of stake. ) Can provide more.

In addition, if the second coin is converted into a stake in the process of converting the second coin into a stake, the second coin is not destroyed but is frozen, and the frozen state is released when the stake is subsequently converted to the second coin.

Furthermore, in order to prevent the stale token of the user who issued the token, the token issuer may allow the token holder to deposit the first coin at a predetermined ratio of the token issue price in the token issuer's balance. Here, the deposit is provided back to the issuer's balance when the issuer executes the contractual content with the buyer. If the token becomes a stale token, the deposit above will be provided to the buyer as a means of compensation for the buyer. When the deposit is provided as the issuer's balance, the deposit may be provided to the second coin at a predetermined ratio in the deposit as a reward for the issuer.

The blockchain-based gift certificate token distribution system 200 may continuously increase the issuance amount of the second coin to prevent a situation in which the stake is monopolized or oligopolized to a specific gift certificate token issuer. In addition, the maximum amount of gift voucher tokens that can be issued per voucher token issuer can be limited.

Blockchain-based voucher token distribution methods can be largely divided into issuance of voucher tokens, purchase of voucher tokens, voucher token transactions, and confirmation of the use of voucher tokens.

To issue a voucher token, the issuer requests a token issuance including token information to the voucher token distribution system 200 and signs the request as a key of the issuer's wallet client 311. 100) generates a block containing the voucher token issuance information and issuance history and record in the blockchain ledger.

In addition, the purchase of a gift certificate token is a purchaser requests a purchase of a gift certificate token to the blockchain server 100, and if the request is signed as a key of the purchaser's wallet client 321, the blockchain server 100 is the owner of the gift certificate token. To the buyer, the buyer's wallet client 321 withdraws the first coin of the amount required for the purchase of the gift certificate token, and the rest of the withdrawn first coin as a fee for the transaction of the gift certificate token Record on the blockchain ledger so that it can be transferred to the operator of the server 100.

The gift voucher token transaction is performed when the buyer transfers the gift voucher token to a third party, and the blockchain server 100 changes the owner of the voucher token to the assignee if the assignor and the assignee sign with the keys of the respective wallet clients 331 and 341. And withdraw the first coin of the amount required for the transaction of the gift certificate token from the wallet client 341 for the first coin of the assignee, and transfer a portion of the withdrawn first coin to the transaction amount of the gift certificate token. Transfer it to the wallet client 331 for the coin, and record the rest of the withdrawn first coin in the blockchain ledger to be obtained by the operator of the blockchain server 100 as a fee for the transaction of the corresponding gift certificate token.

When the confirmation of the use of the gift certificate token is received, a certain percentage of the issue price of the gift certificate token is converted to the second coin and paid to the issuer, and the gift certificate token is recorded in the blockchain ledger to be extinguished.
