Description

The present invention is an invention relating to a system for enabling a holder to dispose of a crypto asset or a token by purchasing / collecting the crypto asset or the token from the holder of the crypto asset or the token.

Cryptocurrencies can be used for the consideration of goods and services among an unspecified number of people via the Internet, there is no public issuer or manager such as a central bank, and legal tender is passed through specialized exchanges. It can be regarded as something that can be exchanged with, and the underlying technology is blockchain. In addition, what is called a token in the crypto asset industry is an electronic one issued using the existing crypto asset platform (blockchain), and can be issued and managed by specific individuals or corporations. It is a thing. Its purpose is various (for example, something close to the points issued by a company, something that can be used for donation activities, something that can be used in a specific game, etc.), but it can be exchanged for cryptocurrency or fiat currency. In addition, since some items that cannot be exchanged for cryptocurrencies or legal tender but can be sent or received are included, in the specification of this application, for the sake of convenience, such tokens are also referred to as "cryptocurrencies" below. do.

Bitcoin is well known as a crypto asset, but there are many types of crypto assets other than Bitcoin, and typical ones include Ethereum, Litecoin, Ripple, Monacoin, etc. Many more crypto assets have been created. Cryptocurrency assets can be used as a means of payment for purchases of goods and services, and a means of remittance between individuals. On the other hand, crypto assets have attracted attention as a target of investment in recent years, and there was a time when they soared, but nowadays, many crypto assets are less valuable than they were when they were issued, and some of them have lost their value. Since there is no central manager for crypto assets, there is no unified trading market, and the management of trading rules, conversion rates with legal tender, and fees are left to each exchange. Therefore, even if cryptographic assets are disposed of, if there is no market transaction, there is only a way to sell them by bilateral transaction, but in such a case, it is difficult to find a buyer. If the price of crypto assets held falls and the price cannot be expected to rise, it is desirable for accounting and tax purposes to dispose of them and fix the loss, but the value of crypto assets has declined or is lost. Asset holders are forced to continue to hold these crypto assets without being able to sell or dispose of them, and it is hoped that this problem will be resolved by some means.

The applicant attempted to investigate the prior art related to the solution of the above-mentioned problems. For example, many patent applications have been filed in connection with "virtual currency", "cryptocurrency" or "cryptocurrency", and regarding the transaction, for example, those related to a system for executing remittance such as the following patent document. be. However, these documents do not disclose prior art related to the above problems. Within the scope of the applicant's search, no prior art could be found to solve the above problems.

It is a block diagram which shows the schematic structure of the system by this invention. It is a figure which shows the flow of operation and processing performed between a system server and a user terminal provided in the system by this invention. It is a figure which shows the example of a certificate. It is a figure which shows the other form of the flow of operation and processing performed between a system server and a user terminal provided in the system by this invention.

Hereinafter, an embodiment of a cryptographic asset purchase / take-back system (hereinafter referred to as “the present system”) according to the present invention will be described with reference to the drawings. The "user" described in the following explanation means a cryptographic asset holder (including individuals and corporations) who wishes to dispose of cryptographic assets and uses this system. In addition, "purchase" of cryptographic assets means paying the user for the receipt of cryptographic assets, and "collection" of cryptographic assets means cryptography from the user for free or for a fee (the user pays a fee). Receiving assets.

FIG. 1 is a diagram showing an overall configuration of an embodiment of this system. This system is provided by a system server 2 to which a user terminal 4 (including a smartphone, a tablet terminal, and a personal computer) having a network connection environment including the Internet and a display function can be connected via a network.

The system server 2 functions as a web server or the like, and upon receiving an access or request or instruction from the user terminal 4, each function indicated by a reference number a to g, that is, a menu display function a, a user registration processing function b, Each function of the fee payment acceptance processing function c, the fee receipt confirmation processing function d, the crypto-asset remittance acceptance processing function e, the crypto-asset remittance receipt confirmation processing function f, and the certificate issuance processing function g is executed. The system server 2 generates, registers, updates, extracts, calls, etc. data for a data file held by the system server 2 or held externally by the cooperation of a computer program and computer hardware to perform processing related to the execution of these functions. Processing, accessing the external system, acquiring data from the external system, etc.

Next, the flow of processing in this system will be described with reference to FIG. FIG. 2 is a diagram showing an example of a processing flow in this system. In FIG. 2, the user terminal 4 is a communication device (including a smartphone, a tablet terminal, and a personal computer) used by the user to use the system.

The system server 2 opens a homepage that introduces the services of this system on the Internet, displays a menu for user registration, etc. for users who are interested in disposing of cryptographic assets, and allows users to access them. I am urging (S1).

When the user terminal 4 accesses the user registration application menu provided by the system server 2 and receives the registration application (U1) from the user, the system server 2 displays an input screen for user registration on the user terminal 4. Display (S2). The information required for user registration is as follows.

・ First and last name or first name ・ E-mail address ・ Information for confirming (identifying) the person or corporation The information for confirming the person is information that can be identified as the person or the corporation in combination with the first and last name or first name. For example, an address, an individual number, a corporate registration number, and the like. Since this system finally issues a certificate to the user, in order to prevent user registration due to pseudonym or spoofing, a copy of the person or corporate verification documents (driver's license, resident's card, copy of register, etc.) is also registered as a user. It is desirable to ask for information.

When the user registration information is transmitted from the user terminal 4 (U2), the system server 2 performs user registration by storing the received user registration information in the user registration information file 5 (S3).

When the user registration is completed, the system server 2 causes the user terminal 4 to display the fee payment guidance screen (S4). In this embodiment, the user can use this system on the premise of payment of a fee. On the fee deposit information screen, the fee amount and payment method are displayed. As for the payment method, the specified payment method may be displayed or the user may be allowed to select from multiple payment methods. For example, it will be possible to select from credit card, electronic money, bank transfer, crypto asset settlement, etc. Although not displayed in FIG. 2, when the user is made to select a payment method from a plurality of payment methods by pull-down or the like on the application fee payment guidance screen, which payment method is selected is transmitted to the system server 2. ..

Assuming that the fee deposit process has been performed on the user terminal 4 according to the designated payment method or the selected payment method (U3), the system server 2 may use the relevant external financial institution system or the related external financial institution system according to the designated or selected payment method. By accessing the payment system 6 to obtain the payment account data, or by receiving the payment information from the external financial institution system or the payment system 6, the payment confirmation process of whether or not the fee has been paid from the user is executed ( S5).

If the payment cannot be confirmed (S6), a standby screen (for example, "Please wait until the payment confirmation is completed" is displayed) is displayed on the user terminal 4 side (S7), and the payment confirmation process (S5) is repeated.

When the payment is confirmed by the payment confirmation process (S5) (S6), the system server 2 causes the user terminal 4 to display the cryptographic asset remittance guidance screen (S8).

On the crypto asset remittance guidance screen, the user is prompted to enter the following crypto asset remittance details.

・ Types of crypto assets that you want to buy / collect ・ Quantity of crypto assets that you want to buy / pick up ・ Wallet address of the sender when the user remits crypto assets Here, the remittance of crypto assets is owned by the user Sending the cryptographic assets you are using from your own wallet to the wallet of the service provider of the system server 2. The wallet is like an electronic wallet for storing cryptographic assets as an image, but it is actually software for managing "private key", "public key", and "address". When a user wants to transfer crypto assets to the service provider, this transaction information is encrypted using the user's private key and sent to the P2P network together with the public key. In the P2P network, work is performed to verify whether the transaction information is correct, and if the content is correct, the remittance of the cryptographic asset to the address of the service provider is completed.

Regarding the type of cryptographic asset, the user may be made to select the type by pull-down or the like, and if it is not a candidate for selection, the user may be made to input characters. When the user completes the input of the cryptographic asset remittance detailed information, the cryptographic asset detailed information is transmitted to the system server 2 by operating the send button or the like (U4).

When the system server 2 receives the detailed information of the cryptographic asset, the system server 2 displays the wallet address of the remittance destination of the cryptographic asset on the user terminal 4 (S9). The wallet address of the remittance destination is displayed after receiving the detailed information of the cryptographic asset because the wallet address of the remittance destination of the cryptographic asset may differ depending on the type of the cryptographic asset.

The user who receives the wallet address of the remittance destination transfers the cryptocurrency assets from the wallet of the cryptocurrency assets owned by the user to the wallet address of the specified remittance destination. Alternatively, it is performed via a wallet management system or the like (U5).

The system server 2 determines whether or not the remittance of the corresponding cryptographic asset has been received from the user in the specified remittance destination wallet based on the cryptographic asset remittance detailed information (cryptocurrency asset type, quantity, sender's wallet address). The remittance receipt confirmation process to be confirmed is executed (S10). The remittance receipt confirmation process can be performed by accessing the website of the cryptocurrency exchange or wallet management system 8 that operates the wallet of the remittance destination and checking the transaction history of the wallet, or from the cryptocurrency exchange or wallet management system 8 on a regular basis. This is done by checking the wallet transaction history information 7 that has been accumulated by taking in the transaction history information on target or at any time.

If the remittance receipt cannot be confirmed (S11), a standby screen (for example, a screen displaying the message "Please wait until the remittance receipt confirmation is completed") is displayed on the user terminal 4 side (S12), and the remittance receipt confirmation process (S12). S10) is repeated.

When the remittance receipt is confirmed by the remittance receipt confirmation process (S10) (S11), the system server 2 sends a receipt confirmation notice to the user terminal 4 (S13). In addition, a cryptographic asset purchase / take-back certificate containing the following details is issued based on the user's information and cryptographic asset remittance detailed information stored in the user registration information 5 (S14).

・ Specific information such as the surname or first name and address of the person to be issued ・ Date of purchase / collection (date of receipt of cryptographic asset remittance)
-Type and quantity of cryptographic assets purchased / collected-Display of fees paid by the user at the time of purchase / collection The purchase / collection certificate is issued as an electronic document that cannot be rewritten or changed, and is sent to the user terminal 4. It may be sent, or the certificate may be printed on paper and sent to the user. FIG. 3 shows an example of this certificate.

FIG. 3 shows an example of a receipt issued as a set and a receipt of fees after confirming the receipt of cryptographic asset remittance from the user, and the receipt corresponds to the cryptographic asset purchase / collection certificate. .. The receipt in Fig. 3 is an example of collecting cryptographic assets free of charge, including the user's first and last name and address, the issuer's address and name, the date of collection as the transfer date, and the type of cryptographic assets collected as the token symbol. The quantity of crypto assets collected is listed. Further, as a description regarding receipt of remittance of cryptographic assets, TxnHash, the wallet address of the user's sender, and the wallet address of the user's remittance destination (that is, the issuer's receipt address) are described. TxnHash (transaction hash) refers to the hash value of the data in which the transaction data in the blockchain is stored with respect to the remittance of cryptographic assets, and corresponds to the transaction number.

In the present embodiment, the fee payment from the user is processed in steps S4 to S7, but in the present invention, this process itself is not essential to be performed at this stage. The issuance of the certificate (S14) requires the receipt of the remittance of the cryptographic asset and the payment of the fee, but the fee payment may be, for example, at the same time as the user registration or after the remittance of the cryptographic asset.

Further, the embodiment described above is an example in which the user's cryptographic assets are collected free of charge, but in the case of receiving the cryptographic assets (that is, purchasing) by paying the consideration, the step S11 in FIG. 2 is performed. Subsequently, together with the receipt confirmation notification (S13) to the user, a screen for displaying the payment method of the consideration and inputting the remittance destination of the consideration is displayed, and the system server 2 is made to send the remittance destination.

Next, the flow of processing according to another embodiment of the present system will be described with reference to FIG. Since the embodiment shown in FIG. 4 has many parts in common with the embodiment shown in FIG. 2, a part different from the processing flow shown in FIG. 2 will be mainly described here.

First, the flow of user registration processing according to the embodiment shown in FIG. 4 (steps C1 to C2, F2 to F3) is the flow of user registration processing shown in FIG. 2 (steps U1 to U2, S2 to S3). Since it is common with, the explanation is omitted.

When the user registration is completed, the system server 2 causes the user terminal 4 to display the cryptographic asset purchase / take-back application screen, so that the user can apply for the cryptographic asset purchase / take-back. Upon receiving the cryptographic asset purchase / take-back application (C3) from the user terminal 4, the system server 2 displays the purchase / take-back target cryptographic asset input screen in order to input the type of cryptographic asset that the user wishes to purchase / take over. Display it on the terminal 4 (F4). When the type of cryptographic asset to be purchased / collected is transmitted from the user terminal 4 (C4), the system server 2 confirms that the type of cryptographic asset transmitted is a type of cryptographic asset that can be handled, and confirms that the type of cryptographic asset is a type that can be handled. In the purchase / take-back cryptographic asset registration information file 9, the type of cryptographic asset to be purchased / picked up in relation to the user is registered (F5). If the user sends a type of cryptographic asset that is not subject to handling, the user terminal 4 may be displayed to indicate that it is not subject to handling so that the user cannot proceed to the following steps. .. Since various types of cryptographic assets appear one after another, there is a possibility that there are some types of cryptocurrency assets that cannot be purchased / collected as a provider of the service according to the present invention due to their characteristics and properties. Therefore, in this embodiment, this check is performed before the user deposits the fee.

The subsequent flow of processing related to the payment of fees (steps C5, F6 to F9) is the same as the flow of payment processing shown in FIG. 2 (steps U3, S4 to S7), and thus description thereof will be omitted.

When the payment is confirmed by the payment confirmation process (F7) (F8), the system server 2 causes the user terminal 4 to display the cryptographic asset remittance guidance screen (F10).

On the cryptographic asset remittance guidance screen, since the system server 2 has already received the type of cryptographic asset to be purchased / collected, the user is urged to input the following cryptographic asset remittance detailed information.

・ Quantity of crypto assets that you want to buy / collect ・ Cryptocurrency details when the user remits crypto assets The wallet address of the sender When the user completes the input of crypto asset remittance details, the send button etc. is operated. Information is transmitted to the system server 2 (C6).

When the system server 2 receives the detailed information of the cryptographic asset, the system server 2 displays the wallet address of the remittance destination of the cryptographic asset on the user terminal 4 (F11). The user who receives the wallet address of the remittance destination transfers the cryptocurrency assets from the wallet of the cryptocurrency assets owned by the user to the wallet address of the specified remittance destination. Alternatively, it is performed via a wallet management system or the like (C7).

The system server 2 determines whether or not the remittance of the corresponding cryptographic asset has been received from the user in the wallet of the designated remittance destination, the type of the cryptographic asset registered in advance and the detailed information of the cryptographic asset remittance (quantity of cryptographic asset, remittance). The remittance receipt confirmation process to be confirmed based on the original wallet address) is executed (F12). Subsequent processes (steps F13 to F16) are the same as the process flow (steps S11 to S14) shown in FIG. 2, and thus description thereof will be omitted.

In the embodiment of FIG. 4, the fee payment from the user is processed following the purchase / collection target cryptographic asset registration (F5), but the fee payment processing itself is after the cryptographic asset remittance. You may.

In the embodiment of FIG. 4, since the process of confirming whether the type of cryptographic asset that the user wants to purchase / collect can be handled before the deposit processing is performed, the cryptographic asset can be handled after the fee is collected. It is possible to avoid the situation where it turns out that there is no kind. On the other hand, in the embodiment shown in FIG. 2, the types of cryptographic assets that can be handled are displayed in advance on the service inquiry homepage, and only certain types of cryptographic assets can be handled at the time of user registration. This situation can be avoided by letting the user consent to the above and registering as a user.
