DApp user fee transaction method through the deposit of a virtual asset (cryptocurrency) according to the present invention is based on a public blockchain, as shown in Fig.3, and operates a decentralized application on the public blockchain. A business operator or individual (“a business operator or individual who operates a DApp” is referred to as a “business entity”. The same applies hereinafter) provides a predetermined service by operating a DApp. Accordingly, the user who uses the DApp pays the fee required to use the DApp.In this process, the fee incurred when using the DApp with the user and the payment and transaction mechanism of the cryptocurrency required for the use of the blockchain will be initiated below. .

First, as shown in FIG. 3, a description will be made based on a public blockchain, that is, a blockchain platform.

For reference, BOS coin is Korea's first blockchain-based cryptocurrency that conducted an ICO. BOS stands for Blockchain Operating System.

BOS (Blockchain Operating System) coin is aiming for a blockchain-based financial platform. Investment funds can be raised through Boscoin-based public financing (PF), and can be used for various services such as payment, settlement, remittance, commerce, travel, and mobility. Boscoin makes important decisions through voting based on the parliamentary network. In November 2018, Boscoin opened the main net, Sebak, and applied the self-developed ISAAC algorithm.

First, as shown in Figs. 4 to 6, the method of trading a DApp user fee through a cryptocurrency deposit according to the present invention is a decentralized applacaion on a block platform based on a public blockchain. dApp), a method for a fee transaction between a service provider and a user using a DApp, comprising: (S10) depositing a cryptocurrency by a business operator operating the DApp; (S20) the step of using a resource of the blockchain platform through the operator of the DApp; And (S30) a step in which a predetermined portion of the cryptocurrency deposited by the operator is paid to the node operator of the blockchain platform, respectively.

As shown in Figures 5 and 7, unlike the conventional Ethereum blockchain platform-based fee payment mechanism, the user who uses the DApp initially pays a key Cryptocurrency (transaction). ), and there is no need to store it in the user's own electronic wallet.

As shown in Figs. 5 and 7, a business operator that operates a DApp and provides a service pays and purchases the basic cryptocurrency of the blockchain and deposits it in the business's own electronic wallet (account) 20.

Thereafter, as shown in Figs. 6 and 8, the users of the DApp use the services provided by the DApp, and in the process of such use, the DApp uses the resources of the blockchain platform.

The fee required for the use of the DApp is that the user pays the fee and purchases a coin such as B coin according to the fee system required by the DApp itself, and the user pays the DApp usage fee through the purchased B coin, but the DApp operator Profits are generated through fees generated when paying B coin.

As shown in Figs. 7 and 9, the cost incurred in using the DApp is deducted from the underlying cryptocurrency deposited by the business operator.

As shown in Figs. 7 and 9, the deducted key cryptocurrency can be paid for each node operator of the blockchain platform as much as the resource is used.

The resources of the blockchain platform mean network resources, and the resources mean CPU (central processing unit), RAM (Random Access Memory), network usage fees, storage space usage fees, etc.

The cryptocurrency that the operator pays and deposits in advance in Figure 5 and can be understood as a concept of pre-deposit or recharge.These cryptocurrencies are key to the operators of each node of the blockchain platform according to the use of the blockchain platform by DApp. Since it must be paid in currency, it is desirable that the currency deposited (or charged) by the operator is the key cryptocurrency commonly used in the provided blockchain platform.

As described above, the cryptocurrency deposited in advance by the business operator is stored in the business’s own electronic wallet, which is a term commonly used in the industry, and can be understood as an individual dedicated account for a business operator. .

In addition, a certain portion of the cryptocurrency is paid to the node operator's electronic wallet, and it is preferable that the node operator's electronic wallet is also a dedicated account for trading key cryptocurrencies allocated to the node operator.

As shown in FIG. 7, in the case of step (S10), steps (S11) to (S13) may be included.

First, as shown in FIG. 7, a step (S11) of opening an electronic wallet by a business operator, a step (S12) in which a (keystone) cryptocurrency is paid and purchased by a business operator (S12), and It may include a step (S13) of depositing the cryptocurrency purchased after payment in the business's own dedicated electronic wallet.

In other words, in order to provide services through DApps within the system of the blockchain platform, a business operator opens an electronic wallet for trading key cryptocurrencies on the blockchain platform.

In addition, the operator has no choice but to use the resources of the blockchain platform to provide services through the DApp, and in order to pay for this, the operator pays and purchases the underlying cryptocurrency.

Thereafter, the business operator deposits the purchased cryptocurrency in the business’s own electronic wallet, that is, an account.

As shown in FIG. 8, the step (S20) may selectively include steps (S21) to (S23).

First, the user signs up as a service user of the DApp in order to receive the service of the DApp.

Thereafter, as shown in FIG. 8, the user uses the service of the DApp.

In this process, after signing up as a service user of the DApp, the user may need to purchase a separate coin, such as B coin, provided by the DApp in order to use the service of the DApp.In this case, the user may need to purchase a DApp service after step (S21). , As described above, a separate coin provided by the DApp is paid for and purchased by paying a fee.

Here, in step S22 of FIG. 8, the separate coin, for example B coin, paid and purchased by the user, is of course deposited in the user's individual electronic wallet.

Since users only need to purchase and use the coins required by DApp #1 to use DApp #1 provided by operator #1, they purchase and deposit the base currency in their wallet as before and use the service usage fee and fees separately. There is no need for the cumbersome process of the back at all.

As shown in FIG. 9, in the case of step (S30), steps (S31) to (S33) are selectively included.

Here, in the case of step (S31), when the user uses the DApp, a predetermined portion of the key cryptocurrency deposited by the operator, for example, the key cryptocurrency, is paid, and then, as shown in step (S32), the user's electronic wallet The deduction is made by a predetermined portion of the cryptocurrency. Thereafter, as shown in step (S33), a predetermined portion of the paid cryptocurrency is paid to the node operator of the blockchain platform.

Of course, in this process, not only is the quantitative evaluation of the part that used the resource, but also which resource among the resources was used quantitatively, and equally distributed to the node operator corresponding to the resource or the resource resource It can be paid proportionally or in conjunction with use.

As shown in FIG. 10, the cryptocurrency previously paid and purchased by the business operator, for example, the basic cryptocurrency, is not required to be purchased only by the business operator.

In other words, if the user is a supporter, fan of the service, or a service for the purpose of public interest, the user purchases a key cryptocurrency, e.g., a key cryptocurrency, and then donates, transfers, transfers, etc. It can be deposited or charged in the wallet.

The scope of the rights of the present invention is determined by the matters described in the claims, and the parentheses used in the claims are not described for selective limitation, but are used for clear elements, and descriptions in parentheses are also interpreted as essential elements. It should be.
