In recent years, trading of crypto assets has become popular. Many crypto assets use blockchain technology, a technology for building distributed databases. This is a system in which multiple nodes connected to each other using a P2P (peer-to-peer) network exchange data structures called transactions that record transactions, data structures called blocks containing one or more transactions, etc. It operates by synchronizing and sharing. A distributed database built using blockchain technology is simply called a blockchain.

Currently, there are many crypto assets and blockchains that record their transactions, such as Bitcoin, which is the most widely known crypto asset, and Ethereum, which has an autonomous program execution function called smart contract. ing. Cryptocurrency assets that apply blockchain technology have high availability (the system can be used whenever the user wants to use it), integrity (there is no risk of falsification or loss, and the consistency of recorded information). auditability (the provenance of recorded information can be confirmed by any third party), decentralization (there is a third party that must be trusted to use the system) It is attracting attention as a new means of recording value because it has many features such as: Additionally, there are crypto assets that can be exchanged for legal currency or crypto assets of other brands through businesses such as crypto asset exchange businesses.

Furthermore, a type of crypto asset called NFT (non-fungible token), which is used to express unique value, can be used as a means to record specific rights, appraisal certificates for works of art, etc. in a distributed database. It is now possible to do so. Since many NFTs have a function to transfer ownership between crypto asset addresses, it is possible to transfer NFT ownership between individuals or by bidding through an auction-style web service. be.

However, in many crypto asset blockchains, users of the crypto asset are managed by identifiers called addresses, making it difficult to identify the person who truly owns the value. Therefore, it is difficult to identify users of cryptographic assets, especially users who have a history of owning NFTs that suggests specific hobbies and preferences, and to display advertisements to these users to stimulate their desire to spend.

FIG. 5 is a flowchart showing the processing executed by the advertisement output device 1 and the advertisement providing device 2 in this embodiment. Each step shown in FIG. 5 will be explained below.

(Step S10)
Based on the input from the user, the advertisement output management unit 10 recognizes the user's cryptographic asset address.
Specifically, in order to use cryptographic assets on the wallet software, the user inputs a passphrase consisting of a list of a plurality of words called a mnemonic from the information input section 11. The advertisement output management section 10 transfers the information obtained from the information input section 11 to the crypto asset address identification section 13, and the crypto asset address identification section 13 decrypts the crypto asset address of the user and responds to the advertisement output management section 10. do.
Alternatively, the wallet software may generate a crypto asset address on behalf of the user and record it in the crypto asset address storage section 14. In this case, instead of the above procedure, the advertisement output management unit 10 reads the information stored in the crypto asset address storage unit 14, transfers the stored information to the crypto asset address identification unit 13, and The address identification unit 13 identifies the user's cryptographic asset address and responds to the advertisement output management unit 10.
For convenience of subsequent explanation, in the explanation of this example, it is assumed that the crypto asset address recognized in this step is address A, and that address A is involved at the time this step is executed. It is assumed that the transaction history of the crypto-assets is as shown in FIG. 6, and that the brand and quantity of the crypto-assets whose value is currently recorded at address A are as shown in FIG.

(Step S11)
The advertisement output management section 10 transmits information regarding the crypto asset address to the advertisement selection section 21 for the purpose of transmitting information regarding the target for displaying the advertisement.
Specifically, the advertisement output management section 10 inquires about the address A to the blockchain connection section 31. The blockchain connection unit 31 communicates with other blockchain node devices 30 through the blockchain network 3 as necessary, and transfers the crypto asset whose value is recorded at address A as shown in FIG. The brand and quantity are sent as a response to the advertisement output management section 10. The advertisement output management section 10 transmits the address A and the brand and quantity of the cryptographic asset whose value is recorded in the address A to the advertisement selection section 21.
Further, the inquiry to the blockchain connection unit 31 by the advertisement output management unit 10 may be omitted. In this case, instead of the above procedure, the advertisement output management section 10 transmits the address A to the advertisement selection section 21.

(Step S12)
The advertisement selection unit 21 selects an advertisement to be displayed to the user.
Specifically, the advertisement selection unit 21 evaluates whether the information regarding address A received in step S11 matches the display conditions of the advertisement recorded in the advertisement recording unit. In determining whether the display conditions are met, information regarding the address A received from the advertisement output management section 10, information obtained by inquiring the blockchain connection section 31 regarding the address A, and information obtained from the Internet are used. The advertisement selection unit 21 selects an advertisement from among the advertisements that satisfy the display conditions based on the evaluation results.
For convenience of the following explanation, in the explanation of this embodiment, it is assumed that the advertisements held by the advertisement recording unit 20 at the time this step is executed are as shown in FIG. It is assumed that the real-time exchange rate of crypto assets obtained from is as shown in Figure 9.

Here, an example of a method for evaluating compliance with advertisement display conditions in this embodiment will be described.
In evaluating the display conditions of the advertisement whose advertisement ID is recorded as 1 in Figure 8, it is possible to evaluate the display conditions of the advertisement whose value has been recorded in the cryptographic asset address A by determining the cryptographic assets whose value has been recorded in the cryptographic asset address A. The advertisement selection unit 21 inquired of the blockchain connection unit 31 about the transaction history, and the result is as shown in FIG. becomes clear. This indicates that the advertisement whose advertisement ID is recorded as 1 satisfies the advertisement display condition.
The evaluation of the display conditions of the advertisement whose advertisement ID is recorded as 2 in Figure 8 is based on the real-time exchange of crypto assets obtained on the Internet for the brand and quantity of the crypto asset whose value is recorded in the crypto asset address A. This can be done by applying the rates and summing them up, and since these are as shown in FIGS. 7 and 9, it is found that the assessed value of the balance of address A is equivalent to 5.25 million yen. This indicates that the advertisement whose advertisement ID is recorded as 2 satisfies the advertisement display conditions.
In evaluating the display conditions of the advertisement whose advertisement ID is recorded as 3 in FIG.
Since the transaction history of crypto assets involving the address A obtained when evaluating the advertisement whose advertisement ID was recorded as 1 is as shown in Figure 6, there is a transaction with the crypto asset address XYZ. It turns out not to. This shows that the advertisement whose advertisement ID is recorded as 3 does not satisfy the advertisement display conditions.
In Figure 8, advertisements whose advertisement ID is recorded as 4 include advertisements that do not specify display conditions, and can be evaluated as advertisements targeting all users who use crypto assets. It can be seen that the display conditions are met.
From the results of the series of evaluations described above, advertisements with advertisement IDs 1, 2, and 4 satisfy the advertisement display conditions. The advertisement selection unit 21 selects the advertisement whose advertisement ID is set to have the highest priority among these advertisements and whose advertisement ID is 1.

(Step S13)
The advertisement selection section 21 sends the selected advertisement to the advertisement output management section 10, and the advertisement output management section 10 displays it to the user through the advertisement output section 12. In this embodiment, as shown in FIG. 10, the wallet advertisement 46 can be displayed on the wallet software 40.
Note that in step S12, if there is no advertisement that matches the display conditions, the advertisement selection section 21 replies to the advertisement output management section 10 that there is no advertisement to be displayed. In this case, the advertisement output management unit 10 can continue to output the previous advertisement or output nothing regarding the advertisement.

By executing each of the above steps, advertisements can be distributed to crypto asset users.
For example, for a service that targets all users of crypto assets, by registering an advertisement with a blank value for the advertisement display condition, the service's advertisement will be displayed at the time the user attempts to use the crypto asset. It is expected that the effectiveness of advertising will be increased. In addition, since it is possible to identify users who have a history of owning crypto assets of a specific brand or NFTs that indicate particular hobbies and preferences, for example, issuing crypto assets with high taste that can be used for games etc. It is expected that the effectiveness of advertisements will be increased by setting display conditions for advertisements targeted at owners of cryptographic assets that can be used in other games of the same type. Furthermore, by setting display conditions for advertisements targeting users who own crypto assets with a total conversion value exceeding a certain level, for example, advertisements encouraging the purchase of rare and high-value NFTs can be displayed. This allows operators of NFT auction houses and the like to display advertisements to users who have a particularly high desire to purchase NFTs.

Specifically, the store specifies the quantity of crypto assets to be paid for the product/service and the crypto asset address to which payment will be made, and displays them on the POS tablet terminal 6. FIG. 12 shows an example of a display on the POS tablet terminal 6. The user uses a crypto asset wallet app running on a smartphone or the like to transfer the designated brand and quantity of crypto assets to the designated crypto asset address.

(Step S21)
The advertisement output management unit 10 provided in the POS tablet terminal 6 recognizes the user's cryptographic asset address based on the information regarding the transfer of the cryptographic asset sent from the POS system.
Specifically, the above-mentioned POS system recognizes the above-mentioned transfer of the cryptographic asset performed by the user, and sends the data structure of the transaction for executing the transfer of the cryptographic asset to the POS tablet terminal 6. The POS tablet terminal 6 receives the data structure of the transaction through the information input unit 11, the advertisement output management unit 10 sends it to the crypto asset address identification unit 13, and the user's crypto asset address is determined from the response obtained. Recognize.

(Step S22)
The advertisement output management section 10 transmits the user's cryptographic asset address recognized in step S21 to the advertisement selection section 21 for the purpose of transmitting information regarding the target for displaying the advertisement.

As for step S23, the gist of the process is the same as that of step S12 in the first embodiment, so a redundant explanation will be omitted.

(Step S24)
The advertisement selection section 21 sends the selected advertisement to the advertisement output management section 10, and the advertisement output management section 10 displays it to the user through the advertisement output section 12. In this embodiment, as shown in FIG. 13, it can be displayed like a POS advertisement 60 on the display of the POS tablet terminal 6.

By executing each of the above steps, advertisements can be distributed to those who use crypto assets to pay at stores.
