Description

The present invention relates to electronic commerce or electronic remittance, and more particularly, to settlement agency for electronic commerce or electronic remittance using virtual currency with a limit secured by cryptocurrency based on block chain technology.

In the real economy, fiat money such as cash has traditionally been used as a means of payment for providing goods and services. Electronic money belonging to Central Bank Digital Currency (CBDC), which electronically implements functions, is used as an electronic payment means. ) cannot be published or distributed by anyone under the relevant laws.

In this way, since the authority to manage and supervise the issuance and distribution of currency has been centralized in the past, we will break away from this situation and build a system based on mutual monitoring through decentralization. Recently, a new concept of currency issuance and circulation technology such as a digital-based virtual currency or cryptocurrency has attracted a great deal of attention.

A virtual currency is a digital asset or a virtual asset, and is a currency or token that is used in a virtual settlement or environment corresponding to a legal currency.

Cryptocurrency is a digital asset or virtual asset that belongs to or has the same meaning as virtual currency, and in brief, the technical background is that ownership or transaction status of cryptocurrency is continuously recorded in a block that acts as a ledger. Blocks are formed as they are being processed, but these blocks are connected in a chain based on the blockchain (Blockchain), leaving a transaction record, node (Distributed Ledger) by Node (Node), decentralized It is embodied as a technology for preventing double spending by mutually verifying through the Internet, and a representative cryptocurrency is Bitcoin.

However, with cryptocurrencies such as bitcoin, the greater the number of mining participants who create a transaction ledger and receive rewards, the higher the difficulty. can become difficult and require significant computer power to record and document transactions. Moreover, due to the characteristics of distributed ledgers, the processing speed is slow, and the higher the rarity, the higher the value. .

In order to complement this, recently, several types of cryptocurrencies with various characteristics based on or applied to blockchain or smart contracts have been announced, and currency is linked to the real economy in various places. I am trying to circulate as In particular, in the case of e-commerce payment, the user can immediately settle or remit with the cryptocurrency held by the user, immediately convert it to legal currency and use it for payment according to the cryptocurrency market price at the time of using e-commerce, or the payment agency Attempts have been made to exchange it for cryptocurrency issued by itself and use it for settlement. However, the problem with payments that change the ownership of the cryptocurrency itself is that in order to use electronic commerce, the cryptocurrency must be purchased in advance or exchanged through an exchange for each payment. Therefore, from the standpoint of merchants who receive cryptocurrency as payment, there is a possibility that losses will occur due to the volatility of the cryptocurrency value as soon as it is exchanged for fiat currency each time or after settlement. cannot be ruled out. Moreover, if the user cancels the payment and the cryptocurrency is refunded, if the value fluctuates, there is a fatal problem that the refund will be less than the cryptocurrency originally used for the payment. And above all, the speed at which blockchain technology creates and records a ledger is extremely slow compared to the computer power used. Alternatively, the method of using them interchangeably has a very large problem and is inefficient.

Therefore, in the case of cryptocurrencies with variable values, there is still a limit to replacing fiat currencies in electronic commerce or electronic remittance due to the nature of the assets to be owned. In the case of cryptocurrencies such as Coin), the problem of value fluctuations at the time of payment can be solved, but the disadvantages of conventional cryptocurrencies as described above (cross-validation to prevent double spending) slow processing speed), it is inefficient for electronic payments that require real-time and fast payment processing.

Recently, in various financial transactions using cryptocurrencies, there is a mixture of centralized finance (CeFi, Centralized Finance) and decentralized finance (DeFi, Decentralized Finance). A lending brokerage system that reflects the market price with cryptocurrencies as collateral between individuals or between individuals and institutions (organizations) will emerge. However, from the user's point of view, there is a disadvantage that if a loan is made in advance for electronic commerce transactions or electronic remittances that may occur at any time, interest must be paid even if the funds are not used. More users could incur higher transaction fees and, in some cases, were more risky as transactions or assets were not guaranteed.

On the other hand, credit settlement methods using credit cards are often used in electronic commerce (purchasing products from online/offline merchants) in the real economy.

In other words, after pre-purchasing with a credit card, which is a document that can be settled instead of legal currency, settlement is made (hereinafter referred to as deferred payment settlement). If you settle the product price with a credit card issued as a credit card, instead of the user, the credit card company will prepay the settlement price to the member store after deducting a certain fee, and after a certain period, the user will receive the product It is a method of payment. It takes a lot of capital cost to become a credit card company, and you have to bear a high risk of refunding the settlement amount (user's delay in payment or loss), so it takes a lot of effort to verify the creditworthiness of the user. For new businesses, the barriers to entry into the market are extremely high.

In particular, in the early days of electronic commerce, credit card companies did not have a means of communicating credit card payments with offline merchants, and VAN (Value Added Network) companies, which provided communication networks, entered the middle, and credit card companies and online In addition, PG (Payment Gateway) company enters the business as an electronic payment settlement agency between the member store, so many intermediate payment steps have to be taken, and from the standpoint of the member store, there is no choice but to bear a high fee. It consists of no structure.

Recently, a deferred payment system has been introduced that verifies the creditworthiness of the user by utilizing big data, etc., and gives a small amount limit. For general SMEs to enter, the risk was high and they had no choice but to bear the financial burden.

Another method of electronic money transfer in the real economy is to make a deposit in a bank (including an Internet bank) in advance and then transfer the funds to another user's bank account within the scope of the deposit. Each transaction had a different bank, and there was the problem of transfer fees, and there was the inconvenience of having to make deposits in advance each time.

The problem to be solved by the present invention is to freely use virtual currency for electronic payment within a given limit without having to pre-purchase or exchange cryptocurrency each time, With the value of cryptocurrency as a virtual asset, you can easily purchase products in advance through online or offline e-commerce without having legal currency or a credit card, and then pay the price later.
