Description

Apparatus and method for creating a virtual currency account using a telephone number

The present invention relates to an apparatus and method for generating a virtual currency account using a phone number.

At the beginning of 2018, demand for altcoins began to rise significantly as Bitcoin exhibited a price stagnant. Here, alt-coin refers to an alternative cryptocurrency other than Bitcoin (BTC, Bitcoin), and is an abbreviation of Alternative coin. Ethereum is the most famous altcoin, and Ripple, Litecoin, Monero, and EOS are also among the major altcoins. Until March 2017, Bitcoin’s market capitalization share in the entire cryptocurrency market reached 85%. However, due to the rise of altcoins, including Ethereum, the share of Bitcoin sharply decreased, reaching the level of 36% in early 2018.

However, it is still very difficult for many people to purchase these altcoins. First of all, in order to own an altcoin, you have to pay a fee. It is difficult for the majority of the public to invest real money in digital assets that are still unfamiliar concepts, and for this reason, the spread of altcoins is only 1~2% of the total internet access population. And even if you buy altcoins, how to open an electronic wallet account and manage public and private keys to participate in ICO, how to trade altcoins in various cryptocurrency exchanges after going through tight KYC procedures, and expensive GPUs It is difficult for ordinary people to easily perform both methods of purchasing and mining altcoins by selecting an appropriate mining pool. In addition, there was a barrier to purchasing altcoins due to the fact that the risk of losing investment due to very high price volatility exists.

Due to the high entry barrier for altcoins of advertisers, although there is a very big advantage in executing advertisements with altcoins and paying advertisers, from the standpoint of general advertisers, advertisements are executed with altcoins rather than fiat currency. And it was very difficult to pay (withdraw).

In addition, it was very difficult for altcoin developers to promote and sell their own altcoins. Only some of the advertisers have access to altcoins, demand is concentrated on only the top 1% of altcoins, and as major advertising platforms such as Google/Facebook stop advertising ICOs, it has become difficult to promote. . In addition, it is difficult to secure the initial advertisers of the altcoin and secure the initial use. After all, it is very difficult to create and secure altcoin distribution and price systems.

The effect of being able to differentiate compensation according to the aggressiveness of providing personal information and whether or not an advertisement mission is performed occurs, and the compensation according to the advertisement activity is counted as an advertisement token in the advertisement module installed in the application, and the advertisement device receives it and receives a specific There is an effect that can be exchanged for an altcoin, and in some cases, if the advertiser is an altcoin developer, the altcoin developer can exchange it for the altcoin of the altcoin developer with an advertisement token of the advertiser who is rewarded with an advertisement. The effect of making it possible to pay advertising costs with this coin is generated.

The mining management module is a module for receiving mining information from the advertisement module, and determining compensation information, which is the legal currency value corresponding to the mining information for the corresponding mining session or the number of altcoins corresponding to the advertised behavior of the advertiser.

Compensation information according to an embodiment of the present invention may be differentially applied according to the advertiser's personal information disclosure level (a level according to the disclosure of anonymous information/disclosure of personal information, or a level according to the number of personal information attributes). For example, (1) providing a uuid and allowing the use of uuid in the advertisement management module (anonymous information), (2) providing simple personal information such as name and phone number, and restricting the use of simple personal information in the advertisement management module When permitted (providing a phone number according to another embodiment of the present invention is essential), (3) providing in-depth personal information use such as photos, passports, employment certificates, and balance certificates, and using in-depth personal information in the advertisement management module The level of personal information disclosure can be differentiated in the case of allowing the According to this, the advertiser can voluntarily use personal information for compensation, and as the utilization of personal information is maximized, the targeting of advertisements becomes more sophisticated, and thus the advertisement unit price is improved.

In addition, according to an embodiment of the present invention, simple personal information and deep personal information including information corresponding to the advertiser's real name/pseudonym are stored in the advertiser client, and the advertisement module-generated key storage of the advertiser Information (key store data) may be stored in the block chain included in the token management module together with information on the scope of disclosure of personal information of the advertiser. According to this, since the advertiser can adjust the disclosure range of personal information at any time, the dynamic use and deletion of personal information is possible according to the advertiser's need for altcoin compensation. In addition, even when the advertiser changes the client's device, the advertiser's information is stored in the block chain with the advertiser's phone number and key store data as the primary key, so that the advertiser can Enter personal identification information such as your password, fingerprint information, and face recognition information (face landmark information, face embedding vector, etc.) in the advertisement module, and directly store the advertiser’s existing data (advertising token) in the token management module’s blockchain. information, personal information disclosure scope, compensation information, etc.) is available. In the advertiser's key store data according to an embodiment of the present invention, in the advertiser's public key-private key pair generated by the advertisement module, the password for the advertiser's application or the advertiser's fingerprint It may mean data generated based on the encrypted private key by encrypting the private key with the integrated identification information that integrates personal identification information such as information and a phone number. According to this, even when the personal identification information is duplicated by two or more users, there is an effect that the uniqueness (identity) of the integrated identification information is secured. For example, passwords may be duplicated by more than one user, and if the private key is encrypted with only the password, the key storage information cannot be stored in the block chain due to security risks. Also, in the case of fingerprint information or facial information (Facial ID), a vector value in which a fingerprint or face is embedded may be duplicated in two or more users according to a fingerprint recognition algorithm or a face recognition algorithm. Even in this case, if the private key is encrypted using only fingerprint information or face information, a security risk occurs.

In addition, according to an embodiment of the present invention, an advertiser can request statistical data of an advertiser for the transmission/distribution of a specific advertisement, and the statistical data of the advertiser is applied to a query transmitted from the advertisement management module to the advertiser client. By making the advertisement module of the advertiser client transmit the dummy value in which the personal information is categorized, it may be configured to be stored and processed in the web server of the advertisement device or the block chain of the token management module. Accordingly, the block chain included in the token management module according to an embodiment of the present invention can record the advertiser's key storage information, personal information disclosure range, compensation information, and advertisement token information, and the web server By recording statistical data for specific advertisements or specific altcoins, the effect of composing a hybrid blockchain occurs. Accordingly, there is an effect of being able to provide highly reliable advertiser statistical data (advertisement performance data) to advertisers without causing a serious load on the block chain.

Statistical information of an advertiser according to an embodiment of the present invention may mean statistical information generated in an advertisement module based on personal information of an advertiser stored in a client of the advertiser, and storing the public key/key of the advertiser It can be stored in the blockchain of the token management module along with information/phone number, etc. Statistical information of an advertiser according to an embodiment of the present invention may include personal information such as gender, age, region, occupation, academic background, information related to application use, information about the advertisement, etc., and is categorized into dummy As a value, it can be recorded in the block together with the advertiser's withdrawal account. According to this, the advertisement device does not store or secure personal information while the personal information is preserved in the client of the advertiser, and the advertisement device executes the target advertisement only with anonymous information or statistical information. The effect of being able to differentiate compensation according to the aggressiveness of providing personal information and whether or not an advertisement mission is performed occurs, and the compensation according to the advertisement activity is counted as an advertisement token in the advertisement module installed in the application, and the advertisement device receives it and receives a specific There is an effect that can be exchanged for an altcoin, and in some cases, if the advertiser is an altcoin developer, the altcoin developer can exchange it for the altcoin of the altcoin developer with an advertisement token of the advertiser who is rewarded with an advertisement. The effect of making it possible to pay advertising costs with this coin is generated.

According to an embodiment of the present invention, the advertisement module may be configured to generate a withdrawal account for the advertiser together with the transmission of the advertiser statistical information according to the information disclosure request of the advertiser. Upon receipt of the advertiser's information disclosure request, the advertisement module generates the advertiser statistical information and outputs a private key and public key pair to generate personal information such as password for the advertiser's application or the advertiser's fingerprint information and facial ID. The private key may be encrypted using the integrated identification information that integrates the identification information and the phone number, and key store data may be generated based on the encrypted private key. According to an embodiment of the present invention, such key storage information can serve as highly secure, anonymous information stored in the block chain of the advertising device or a connected web server. Advertiser statistical information together with key storage information may be stored in the block chain of the token management module or a DB connected to the web server of the advertisement device.

Alternatively, according to another embodiment of the present invention, in the advertisement module, according to the advertiser's initial withdrawal request (withdrawal request generated first while satisfying the withdrawal conditions such as 'advertisement token is more than the amount available for withdrawal'), the advertiser withdrawal account can be configured to create In this case, after an initial withdrawal request of a specific amount for a specific altcoin is input in the advertisement module by the advertiser, the advertiser withdrawal account is created in the following steps, and the advertiser withdrawal account address is entered in the DB of the advertisement device. (Public key) may be configured to be stored together with virtual currency information (eg, a virtual currency symbol/ticker or the name of a corresponding virtual currency issuer) and a phone number.

① Creation of advertiser information in the application module and/or advertisement module of the advertiser client by the input of the advertiser (the advertiser's ID, phone number, etc. are sent to the application server and advertisement device)

② The advertisement module of the application module of the advertiser client generates mining information by performing advertisement actions such as advertisement viewing and community subscription by the advertiser, and transmits the mining information to the mining management module of the advertisement device (community subscription In the case of an advertised action, a specific random code is generated when information about the advertiser is generated by the advertiser's subscription to the application module or advertisement module, and the advertiser corresponds to a specific community chat window configured in Telegram or Facebook Messenger, etc. (can be configured as a way to authenticate community membership by entering a random code)

③ The advertisement device matches the reward information (quantity of advertisement tokens) corresponding to the mining information with information about the advertiser (ID of the advertiser, phone number, etc.) and stores the DB together

④ Create an initial withdrawal request for a specific virtual currency in the advertisement module of the application module of the advertiser client by input from the advertiser. , including the number of withdrawal requests for the amount of virtual currency that the advertiser wants to withdraw)

⑤ The advertisement module generates the advertiser's public key and private key that is used as the address of the advertiser's withdrawal account in the blockchain of the token management module (e.g., RSA (Rivest-Shamir-Adleman) ) algorithm, generated using an asymmetric encryption algorithm such as ECDSA (Elliptic Curve Digital Signature Algorithm))

⑥ Personal identification information is generated in the advertisement module by input of the advertiser's personal identification information (password, fingerprint information, Facial ID, etc.) Generate key storage information by encrypting the private key (according to this, even if personal identification information is duplicated by two or more users, the uniqueness (identity) of the integrated identification information is secured)

⑦ The advertisement module sends a request to create an advertiser withdrawal account including the advertiser's public key, key storage information, and phone number to the token management module of the advertisement device, and the advertiser withdrawal account address (public key) , Sends virtual currency information (eg, virtual currency symbol/ticker or virtual currency issuer name) and phone number to the advertising device (the advertising device stores the advertiser’s withdrawal account address, virtual currency information and phone number in the connected database) ), the token management module generates an advertiser withdrawal account creation transaction corresponding to the advertiser withdrawal account creation request for a new block, and transmits the generated advertiser withdrawal account creation transaction to the block chain network connected by wired and wireless networks. When the block is verified by a specific node, the advertiser withdrawal account creation transaction is recorded on the block chain, and the state change corresponding to the advertiser withdrawal account creation request is completed (the advertiser withdrawal account creation transaction is To : Advertiser withdrawal account address, Token: including cryptocurrency information, key storage information and phone number)

⑧ The advertisement module sends the initial withdrawal request (including virtual currency information and withdrawal request quantity) to the token management module of the advertisement device.

⑨ In the token management module of the advertising device, a withdrawal transaction corresponding to the initial withdrawal request is generated for a new block, the generated withdrawal transaction is distributed to a blockchain network connected by a wired/wireless network, and the block is verified by a specific node. Record the withdrawal transaction in the block chain to complete the state change corresponding to the withdrawal request (withdrawal transaction includes From: advertising fee account address, To: advertiser withdrawal account address, Token: virtual currency information, Amount: withdrawal request quantity)

⑩ From subsequent withdrawal requests, a withdrawal transaction is created for the pre-created advertiser withdrawal account without creating a new account.

According to this, even if the advertiser does not create a withdrawal account for the advertiser on the block chain, it is possible to obtain a reward through the advertisement act immediately after the application is installed. In addition, when a withdrawal request is made, a withdrawal account for the advertiser is automatically created by the advertisement module and the advertisement device, so that it is very easy to create an account on the block chain.

In addition, the public key, which is the address of the advertiser withdrawal account (advertiser withdrawal account address) created by the initial withdrawal request, is matched/mapped with virtual currency information and phone number in the DB of the advertising device and stored Therefore, when remittance of virtual currency held by a third party (sender) to the advertiser, the phone number of the advertiser (receiver) stored in the client of the third party and the symbol of the virtual currency to be transferred The effect of being able to use the advertiser's withdrawal account address of the advertiser (recipient) is generated just by inputting the same virtual currency information. When a third party (the sender) remits the virtual currency held by the advertiser (receiver), the following steps can be performed.

① Create a remittance request for a specific virtual currency in the advertisement module of the sender client's application module by input from the sender , including the number of remittance requests for the amount of virtual currency that the sender wants to send money and the recipient's phone number), the advertisement module sends the generated remittance request to the advertising device

② The advertising device requests the recipient's account address (public key) from the DB (request including virtual currency information and recipient's phone number)

③ When a recipient account address matching/mapped to the corresponding virtual currency information and the recipient's phone number is found in the DB of the advertisement device, the token management module creates a remittance transaction corresponding to the remittance request for a new block, and the generated remittance The transaction is distributed to a blockchain network connected by a wired/wireless network, and when the block is verified by a specific node, the remittance transaction is recorded in the block chain to complete the state change corresponding to the remittance request (the remittance transaction is From: sender account address) , To: recipient withdrawal account address, Token: cryptocurrency information, Amount: including the amount of remittance request)

④ If the recipient account address matching/mapped to the corresponding virtual currency information and the recipient's phone number is not found in the advertisement device's DB, the advertisement device sends account creation guide information to the recipient's phone number, and the recipient client sends the advertisement module Install the included application module and proceed to create the recipient account, create a remittance transaction in the token management module when the recipient account is created

According to this, even if you do not remember or use the public key of the block chain, which is difficult to remember or use, you can easily transfer the virtual currency rewarded through the advertised act with just another person's phone number. In addition, users who have created an account through the advertisement module once can use the phone number and virtual currency information instead of the account address as long as the phone number does not change, so the advertisement module plays the role of a virtual currency integrated wallet. occurs

3 is a flowchart illustrating an advertisement flow of an advertisement device using an advertisement module included in an application according to an embodiment of the present invention. As shown in FIG. 3 , the advertisement is performed in the following steps by the advertisement device according to an embodiment of the present invention. At this time, for convenience of explanation, the virtual currency according to an embodiment of the present invention is divided into altcoin and service coin, but service coin and altcoin are a kind of virtual currency, and the scope of the present invention is service coin in a specific case. and altcoin may refer to the same altcoin.

① Service coin deposit stage

Advertisers who are advertisers purchase service coins for altcoin advertisements (advertisements including altcoin airdrops, altcoin bounties, altcoin rewards, community membership, etc.) It is the stage of holding in the deposit account of The service coin is acquired by the advertiser by purchasing it with fiat currency or other cryptocurrency at a cryptocurrency exchange, or by transacting with P2P. In this step, a transaction corresponding to a change in the state of a specific amount of service coins to the deposit account configured in the service coin block chain (deposit transaction, From: advertiser account address, To: deposit account address, Token: service coin, Amount: Deposit amount) will be distributed and recorded on the blockchain of the service coin.

According to another embodiment of the present invention, the advertising service principal may own the deposit account. In this case, in this step, a service coin remittance transaction including a remittance request to transfer a specific amount of service coins from the service coin advertiser account, which is an account of the service coin block chain included or linked to the token management module of the advertising device, to the deposit account is serviced. It will be distributed and recorded on the blockchain of the coin.

② Provision of advertising rights

In the token management module, check the service coin of the advertiser deposited in the deposit account, and grant the advertising service authority for the altcoin sent from the advertiser client or altcoin to be remitted in the future. After the service coin of the deposit account is confirmed by the token management module, the advertiser can freely use the advertisement service by remitting a specific altcoin that they want to spend as an advertisement fee to the advertisement fee account.

③ Altcoin remittance step

The advertiser client creates an altcoin remittance request, which is a request for altcoin remittance that corresponds to the advertisement fee, from the advertiser account of the altcoin block chain to the advertisement fee account, and an altcoin remittance transaction (From: advertiser account address) including altcoin remittance request , To: Advertisement expense account address, Token: Altcoin, Amount: Advertisement amount) is distributed and recorded on the altcoin blockchain. In this step, the token management module can check the altcoin remittance transaction or check the altcoin holding status of the advertisement fee account to generate the advertisement token used in the advertisement module offchain. Due to the advertisement token according to an embodiment of the present invention, the cost incurred in the recording of the block chain is not excessively generated, and the effect of facilitating the advertisement is generated.

Alternatively, according to another embodiment of the present invention, the advertisement token can be pegged 1:1 with fiat currency, and the state change of the advertisement token can also be distributed on the block chain and stored in a record/web server. According to this, when compensation is accumulated for the advertiser, compensation can be accumulated based on fiat currency, and finally, the effect of withdrawing altcoins according to the unit price when the withdrawal is requested occurs.

The altcoin remittance step has been described after the service coin deposit step and the advertisement authority provision step for convenience of explanation, but the scope of the present invention is not limited thereto, and the altcoin remittance is performed before the service coin deposit step or the advertisement authority provision step. It may include cases where

④ Advertisement condition setting step

This is a step of transmitting advertisement condition information generated by setting advertisement conditions desired by the advertiser in the advertiser client to the advertisement management module. The advertisement condition information according to an embodiment of the present invention includes anonymous information such as UUID, simple personal information such as gender, age, region, occupation, academic background, in-depth personal information such as passport photo, information related to application use, and advertisement. information may be included.

The advertisement condition setting step has been described after the service coin deposit step, the advertisement authority provision step, and the altcoin remittance step for convenience of explanation, but the scope of the present invention is not limited thereto, and the advertisement condition setting includes the service coin deposit step, advertisement authority It may include a case made before the provision step or the altcoin remittance step.

⑤ Mining stage

This is a step in which the advertiser executes a specific application in the advertised client and performs an advertisement action to perform mining of an advertisement token, and to generate mining information, which is information about mining, in the advertisement module. The mining may refer to a pre-advertised act set by the advertiser client, such as watching an advertisement, executing an application, performing a specific quest, sharing altcoin posting, or joining a community.

⑥ Mining information receiving step

The advertisement module configured in the application module of the advertiser transmits mining information to the mining management module of the advertisement device, and receives the mining information of the advertiser from the mining management module.

⑦ Ad Token Allocation Stage

The token management module receives the mining information from the mining management module, and allocates an advertisement token to the advertiser based on the mining information. In this case, if there is compensation condition information preset by the advertiser client, advertisement tokens may be allocated based on the mining information and the compensation condition information. According to an embodiment of the present invention, after the legal currency value of the act to be advertised by mining is determined, the advertisement token may be allocated off-chain according to the determined value of the act to be advertised. Off-chain of the advertisement token according to an embodiment of the present invention may mean that it is stored in a database connected to a token management module rather than a block chain.

Alternatively, according to another embodiment of the present invention, the advertisement token can be pegged 1:1 with fiat currency, and the state change of the advertisement token can also be distributed and recorded in the block chain. According to this, when compensation is accumulated for the advertiser, compensation can be accumulated based on fiat currency, and finally, the effect of withdrawing altcoins according to the unit price when the withdrawal is requested occurs.

According to another embodiment of the present invention, the advertisement module of the advertiser client generates and stores the advertisement token based on the mining information, or the mining management module receives the mining information to generate the advertisement token based on the reward condition information. can be configured.

⑧ Altcoin withdrawal request step

When an altcoin withdrawal request is sent to the token management module from the advertisement module of the advertiser client or a predetermined condition (for example, the minimum withdrawal unit) is satisfied, the token management module determines the amount of the advertisement token that the advertiser wants to withdraw. Based on the value (the altcoin and the peg according to one embodiment of the present invention or the peg in fiat according to another embodiment of the present invention) and the market price of other altcoins (the representative value of a specific exchange or the average value of multiple exchanges, etc.) Withdrawal, which is a remittance request that determines the amount of a specific altcoin to be paid to the advertiser, and transfers the specific altcoin whose payment amount is confirmed from the advertisement expense account to the advertiser withdrawal account, which is the advertiser's altcoin account on the same block chain This is the step of creating a withdrawal transaction (From: advertising fee account address, To: advertiser withdrawal account address, Token: altcoin, Amount: withdrawal request amount), which is a transaction that includes a request, and distributes and records it on the blockchain.

At this time, the request for generating an advertiser's withdrawal account according to an embodiment of the present invention is generated by the advertisement module when the advertiser's first altcoin withdrawal request is made. It may be configured to output a private key and a public key pair and transmit a request for generating an advertiser withdrawal account including the corresponding public key to the token management module of the advertisement device. When the token management module receives a request to create an advertiser withdrawal account, it creates the advertiser withdrawal account in a new block using the public key as the advertiser withdrawal account address, and distributes the block to the block chain network connected to the wired/wireless network. When the block is verified by a specific node, it is recorded in the blockchain. In addition, the advertisement module encrypts the private key using the integrated identification information in which personal identification information such as a password for the advertiser's application or the advertiser's fingerprint information and a phone number are integrated, and stores the key based on the encrypted private key. information can be generated.

According to one embodiment of the present invention, since the creation of the advertiser withdrawal account is performed before the advertiser client's altcoin withdrawal request, the advertiser actually creates an altcoin account on the block chain before the altcoin withdrawal request. The effect of actually being able to use altcoins without configuration occurs.

Through the above steps, the effect of improving the advertiser's access to cryptocurrency occurs. According to an embodiment of the present invention, an advertiser who wants to use cryptocurrency or ride on the rise in the value of cryptocurrency does not have any prior knowledge about cryptocurrency (eg, create a wallet in ether-wallet, private key There is an effect that a specific altcoin can be acquired in the existing way (viewing advertisements, playing games, performing specific quests, sharing postings).

For example, an application advertiser with an advertisement module has the same effect as holding an altcoin by assigning an advertisement token pegged 1:1 with and without creating an advertisement fee account. According to an embodiment of the present invention, when an app advertiser wants to withdraw altcoins, at any time, an advertiser withdrawal account is created and altcoins are withdrawn as much as the advertisement token assigned to the advertiser's account in the advertisement module. can

In addition, when an altcoin withdrawal request is received, the advertisement module outputs a private key and public key pair to provide integrated identification information in which personal identification information such as a password for the advertiser's application or the advertiser's fingerprint information and a phone number are integrated. is used to encrypt the private key, and key storage information is generated based on the encrypted private key. Thereafter, the token management module remits the withdrawal request amount of a specific altcoin corresponding to the altcoin withdrawal request to the address of the advertiser withdrawal account corresponding to the public key of the key storage information generated from the advertisement expense account. After that, when the advertiser tries to access the advertiser's withdrawal account, the generated key storage information and phone number are recorded in the block chain together with the advertiser's withdrawal account creation transaction, so personal information such as password or advertiser's fingerprint information There is an effect of being able to access the advertiser withdrawal account only by inputting identification information. In addition, since the generated private key is directly encrypted by the personal identification information and stored in the advertiser client, the advertisement device does not store the private key. By generating the key storage information according to an embodiment of the present invention, the attacker has to additionally find out the personal identification information of the advertiser in order to obtain the private key, and personal identification information without using a complex private key is generated. There is an effect that the service can be used only with and key storage information.

The generation of key storage information according to an embodiment of the present invention may be performed in the following steps.

① Personal identification information is generated in the advertisement module by inputting the advertiser's personal identification information (password, fingerprint information, Facial ID, etc.), and the advertisement module generates integrated identification information in which the personal identification information and phone number are integrated.

② The advertisement module encrypts the generated integrated identification information with the first encryption algorithm (one-way encryption algorithm) to generate the integrated identification information hash value (information input to the first encryption algorithm is the integrated identification information and the first predetermined encryption variable)

③ Create private key encryption information by encrypting the private key with the hash value of the integrated identification information with the second encryption algorithm (two-way encryption algorithm) Integrated identification information hash value, preset second encryption variable)

④ At least a part of the integrated identification information hash value and the generated private key encryption information are integrated and encrypted with a third encryption algorithm (one-way encryption algorithm, for example, a hash function such as SHA3-256) to generate verification information that is a hash value (If at least a part of the hash value of the integrated identification information is integrated with the private key encryption information, decryption becomes impossible even if part of the password is known)

⑤ The advertisement module generates key storage information including the second encryption algorithm, the second encryption variable, the private key encryption information, the first encryption algorithm, the first encryption variable, and the verification information (the integrated identification information hash value itself is in the key storage information) Because it is included and not stored together, the effect of improving the security of the private key occurs)

⑥ The advertisement module sends the generated key storage information to the advertisement device, and the advertisement device creates an advertiser withdrawal account with the key storage information in the block chain through the token management module.

The key storage information according to an embodiment of the present invention may include the following information.

- Information on the second encryption algorithm used for private key encryption (eg, two-way encryption algorithm, eg, AES algorithm)

- The second encryption variable required for the private key encryption algorithm (second encryption algorithm)

- The result of encrypting the private key with the private key encryption algorithm (private key encryption information)

- First encryption algorithm information (eg, one-way encryption algorithm, eg, Scrypt algorithm) used for encryption of integrated identification information (information in which personal identification information and phone number are integrated)

- The first encryption variable required for the encryption algorithm of the integrated identification information (for example, a random variable required for encryption, the length of the result value, CPU/Memory cost, block size, parallelization level, etc.)

- Verification information

When a one-way algorithm is used according to an embodiment of the present invention when encrypting the integrated identification information, it is designed to have a memory overhead when generating a result value, thereby making a brute-force attack difficult.

The private key decryption step according to an embodiment of the present invention is as follows.

① Personal identification information is generated in the advertisement module by inputting the advertiser's personal identification information (password, fingerprint information, Facial ID, etc.), and the advertisement module generates integrated identification information in which the personal identification information and phone number are integrated.

② The advertisement module sends the phone number and virtual currency information to the token management module of the advertisement device, and the token management module searches the phone number and virtual currency information in the block chain, and the advertiser withdrawal account address and password for the corresponding virtual currency Send the stored key storage information to the advertisement module

③ The integrated identification information generated by the advertisement module is encrypted with the first encryption algorithm (one-way encryption algorithm) stored in the key storage information to generate the integrated identification information hash value (information input to the first encryption algorithm is the integrated identification information and key storage information) the first encryption variable stored in

④ The advertisement module generates verification information by integrating at least some of the integrated identification information hash value and the private key encryption information stored in the key storage information.

⑤ The advertisement module verifies the integrated identification information by comparing the verification information stored in the key storage information with the generated verification information (the effect of enabling a quick comparison judgment on whether the personal identification information is accurate by the verification information occurs)

⑥ When the integrated identification information is verified, the advertisement module inputs the private key encryption information, the second encryption variable, and the generated integrated identification information hash value stored in the key storage information into the second encryption algorithm (two-way encryption algorithm) to generate the private key. Print

According to this, even when the advertiser changes a smartphone or installs a new application, the private key can be immediately retrieved only with personal identification information such as phone number and password/fingerprint information/Facial ID, so that the use of the advertiser's withdrawal account The effect of maximizing the UX efficiency for

In addition, since the advertisement module generates personal identification information such as fingerprint information and face information, the same fingerprint information generation algorithm and face information generation algorithm can be used for multiple applications and multiple smartphones, and accordingly, the same fingerprint or face information generation algorithm can be used. The effect that the same embedding vector value is generated for the same face occurs.

4 is a flowchart of an altcoin initial withdrawal request in an advertisement device according to an embodiment of the present invention. As shown in FIG. 4 , the altcoin initial withdrawal request of the advertising device according to an embodiment of the present invention is performed in the following steps. The advertiser's initial altcoin withdrawal request may include a request to create a withdrawal account for the advertiser.

① Receives a request to create an advertiser withdrawal account from the advertiser client's application module. According to an embodiment of the present invention, the advertiser withdrawal account creation request is advertiser information disclosure requesting information disclosure of advertiser statistical information based on the advertiser's anonymous information/simple personal information/in-depth personal information. It may be generated in the advertisement module along with the request or altcoin withdrawal request and sent to the advertisement device.

② The advertisement module generates a private key and a public key pair.

③ The advertisement module generates key storage information by encrypting the private key based on personal identification information such as password or fingerprint information of the advertiser. With such key storage information, the advertiser does not need to memorize or always carry a private key, and it is possible to access the advertiser's withdrawal account only by inputting personal identification information, and to digitally sign altcoin withdrawal requests. is generated

④ The advertisement module sends a request to create a withdrawal account for the advertiser together with the public key and key storage information generated in the advertisement device. The token management module of the advertisement device receives the request for generating a withdrawal account for the advertiser, creates an advertiser withdrawal account with the public key as an address in a new block and includes the key storage information, and stores the generated new block. It is distributed in a blockchain network connected by a wired or wireless network, and when the new block is verified by a specific node, the advertiser withdrawal account is recorded in the blockchain included in the token management module.

⑤ The advertisement module sends an altcoin withdrawal request for a specific altcoin to the advertisement device. In particular, altcoin withdrawal requests can be digitally signed with a private key.

⑥ The token management module can receive the signed altcoin withdrawal request and decrypt it with the public key to verify the signature.

⑦ When the verification of the signature is confirmed, a withdrawal transaction including a withdrawal request for the token management module to withdraw altcoins from the advertising expense account to the advertiser withdrawal account (From: advertising expense account address, To: advertiser withdrawal account address, Token : Altcoin, Amount: Amount of withdrawal request) can be created, distributed and recorded on the blockchain.

Through the above steps, the advertiser does not fall into the problem of creating a wallet or storing the private key through difficult procedures, and it is very simple to send altcoins to the advertiser in the conventional way rather than on-chain until withdrawal. The effect of making it available to the client occurs.

With respect to the embodiment of the advertiser side, FIG. 5 is a flowchart illustrating an embodiment of the advertiser side of the advertisement device according to an embodiment of the present invention. As shown in FIG. 5 , when an advertiser uses an advertisement device according to an embodiment of the present invention, the following steps may be performed.

① This is the stage in which the advertiser installs a specific application. Advertisement module will be included in the application in the same form as SDK.

② Update the advertiser withdrawal account in the advertisement module included in the corresponding application based on key storage information stored in the advertisement module already installed in the advertiser client or based on personal identification information such as fingerprint information. According to this, there is no need for the advertiser to create a new wallet address for every application, and the effect of being able to manage advertisement tokens for all applications is generated.

③ The advertiser performs preset mining according to a specific altcoin or specific application, such as watching an advertisement output by the advertisement management module, playing a game, or joining a community.

④ The advertisement module generates mining information by tracking mining, and transmits the generated mining information to the mining management module. For example, if a specific advertisement is viewed once, mining information including advertiser identification information, advertisement information, viewing time or number information, altcoin information, time information, etc. is generated and transmitted to the mining management module.

⑤ The token management module allocates the amount of advertisement tokens corresponding to the mining information to the advertisers. For example, if a specific advertisement is viewed once, n advertisement tokens may be allocated to the advertiser. Alternatively, after the legal currency or altcoin value of the corresponding mining is determined, the token management module may allocate the advertiser's advertisement token to the advertiser.

⑥ When the advertiser wants to withdraw a specific amount of advertisement tokens to a specific altcoin, the advertiser signs the withdrawal request for the altcoin with the private key and sends it.

⑦ The token management module verifies the corresponding signature with the advertiser's public key.

⑧ When the signature is verified, the token management module generates a withdrawal transaction including a withdrawal request for withdrawing the requested altcoin from the address of the advertisement fee account to the advertiser withdrawal account of the advertiser, and distributes and records it on the blockchain do.

Through the above steps, advertisers can use altcoins without creating and holding a separate wallet and private key for each altcoin, and can acquire and use altcoins in simple ways such as watching advertisements without using any cash. there will be Advertisers can transfer the acquired altcoins to other exchanges to make profits or perform transactions.

As shown in Fig. 9, the advertisement system using a block chain according to an embodiment of the present invention is a deposit account for a specific advertisement and a target to take a reward (advertisement token or altcoin itself) through advertisements. It may be composed of an advertiser withdrawal account, an advertisement Dapp that is an advertisement channel through which advertisements are distributed, and one block chain 30 and IPFS 410 connected to a plurality of Dapps. According to this configuration, advertisers for advertisements are able to register and execute advertisements in an integrated form in multiple advertisement applications, and advertisers use one account (EoA or CA) to form advertisements integrated in multiple advertisement applications. The effect of being able to request compensation occurs.

10 is a schematic diagram illustrating a data flow for one Dapp in an advertisement system using a block chain according to an embodiment of the present invention. As shown in FIG. 10, the advertisement system using a block chain according to an embodiment of the present invention is an advertiser client 200, an advertiser client 320, an advertisement Dapp 400, an IPFS 410, a server ( 420 ), DB 430 , and block chain 30 .

The advertiser client 200 refers to a client, such as a smartphone, PC, node, etc., for an advertiser who intends to advertise or distribute a specific advertisement to an advertisement Dapp to use an advertisement Dapp (Decentralized Application).

The advertiser client 320 refers to a client, such as a smartphone, PC, node, or the like, of an advertiser who wants to mine altcoins registered in advertisements to obtain a reward (advertisement expense account token or altcoin itself).

The advertisement Dapp 400 means a web frontend like the Dapp of the advertisement system, and the web frontend of the Dapp may be composed of a combination of HTML, CSS, and JavaScript (web3js has a large proportion). The advertiser client 200 and the advertiser client 320 interact with the block chain 30 , the IPFS 410 , and the nodeJS server 420 through this front-end application.

IPFS (410, InterPlanetary File System) is a peer-to-peer distributed file system that attempts to connect all computing devices to the same file system. It can also be viewed as a single BitTorrent swarm exchanging objects in a Git repository (a unique identifier for a file and a list of peers that own it). That is, IPFS provides a content addressed block storage model with high throughput by using a content addressed hyperlink that utilizes the hash value of content as an address. It can take the form of a version-controlled file system, a blockchain, or a generalized Markle DAG, a data structure from which you can build persistent web pages. IPFS combines a distributed hash table with incentivized block exchanges and a self-certifying namespace. When IPFS is used, a single point of failure does not occur due to the unexpected termination or destruction of a specific node, and each node does not need to trust each other. According to an embodiment of the present invention, when an advertiser registers an altcoin, a product to be advertised, in the advertisement Dapp 400 for advertisement, the front-end advertisement Dapp 400 transmits the image file and description for the altcoin to IPFS ( 410), the hash of the uploaded file is stored in the block chain 30 and DB 430.

The server 420 is an off-chain back-end server for the front-end advertisement Dapp 400 to communicate with the DB 430 . It is configured to query and receive altcoin information in the database from the frontend through the API. In addition, the DB 430 is configured to perform a search and listing (Listing, for example, a recommendation engine) of altcoins registered under various conditions.

The DB 430 is an off-chain database that is connected to the server 420 to store and index information on altcoins. For example, it may be composed of a database such as MongoDB. Even if all altcoins are uploaded to the blockchain, it is inefficient to display a specific advertisement on the advertisement Dapp 400 and send a query to the blockchain every time various filters are applied. Accordingly, in one embodiment of the present invention, altcoin information is stored and queried using the DB 430 of the Off Chain instead of the block chain 30 .

The block chain 30 is composed of a plurality of blocks that are Linked Lists stored in the memory module 12 of the advertisement device 1 for advertisements, and after a specific block, the advertisement expense account, the advertiser withdrawal account, and the deposit account include In addition, the block chain according to an embodiment of the present invention may separately include a block chain for a specific altcoin. The block chain 30 according to an embodiment of the present invention will be described below.

The mining information tracking module 40 is connected to the advertisement Dapp 400 or the block chain 30 and means an off-chain module that tracks whether the advertiser proves the newly created block by performing (mining) preset credentials do. Mining information according to an embodiment of the present invention includes information on advertisement behavior such as viewing, clicking, and sharing of a corresponding advertisement, solving a quest in a specific game application related to the corresponding altcoin, playing a specific game such as game play time, win or loss, etc. Information, usage information in a specific application related to the corresponding altcoin, etc. may be included, and compensation information that is a standard for a token to be rewarded according to the corresponding mining may be included. As a method of tracking mining information according to an embodiment of the present invention, when an advertiser performs mining within a Dapp, information about the corresponding mining is received through the API of each Dapp, and a unique link of an altcoin is provided in the advertisement Dapp. A method of generating and tracking mining information using a unique link may be applied.

According to an embodiment of the present invention, the limit that can be mined by the corresponding mining may be determined according to the number of service coins purchased by the advertiser. In addition, when a specific advertiser mines a token for a specific altcoin through mining, the service coin purchased by the advertiser may be deducted. Accordingly, advertisers have to purchase service coins with their altcoins or other alternative currency/cash to advertise specific advertisements, thereby generating continuous demand for service coins in the deposit account according to an embodiment of the present invention. Accordingly, the price of the service coin rises, and the profit of this rise is returned to the advertiser who has been mining.

11 is a flowchart illustrating the flow of data according to an embodiment of the present invention. 11, the block chain 30 may include a deposit account 20, an advertiser withdrawal account 32, and an advertisement expense account 31, and a mining information tracking module 40 may be connected. . The advertisement expense account 31 may be configured as a CA (Contract Account) including an advertisement management smart contract according to an embodiment of the present invention, and a deposit account 20 and an advertiser withdrawal account within the block chain 30 (32) refers to an account that acts as a mediator of advertisements within the blockchain. The deposit account 20 may be configured as an External Owned Accouunt (EoA) or a Contract Account (CA), and refers to an account in which service coins are deposited by the request of an advertiser client. The advertising expense account 31 may be configured as a Smart Contract Account that performs altcoin registration and token remittance, and checks whether service coins are deposited in the deposit account. The advertiser withdrawal account 32 may be composed of an EoA (External Owned Accouunt) or CA (Contract Account), is connected to the advertiser's client, and is automatically generated when the advertiser subscribes to the advertisement Dapp. It can consist of accounts on the chain. In addition, the advertiser's withdrawal account 32 performs withdrawal reception and the like according to the history of mining for a specific altcoin in the advertisement expense account 31 .

When deposit account registration is requested (message transaction) through the advertiser client 200, altcoin information (eg, IPFS altcoin information hash value, reward condition information, management account information in the altcoin block chain) and mining It means a module that creates and stores (memory) a deposit account registration transaction including condition information in the advertising fee account 31 and distributes (broadcasts) it to a blockchain distributed network so that at least some nodes share it.

In order for an advertiser to run altcoin advertisements on an advertisement service driven by an advertisement fee account, purchase a service coin, a token of the advertisement fee account (purchase at the exchange and transfer to a deposit account in the block chain, purchase directly from the advertisement fee account, or purchase P2P) ) and can be configured to hold it. In addition, according to another embodiment of the present invention, it may be configured to remit the purchased token to the advertisement fee account together with the registration of the deposit account.

In addition, according to the token transmitted to the deposit account registration module 310 according to an embodiment of the present invention, a benefit in an advertisement (eg, Dapp) connected to the advertisement fee account 31 may be determined. For example, based on the token transmitted from the advertiser to the altcoin registration module, benefits such as search priority or exposure priority in the advertisement Dapp, influence, authentication, and maximum size that can be advertised may be determined. According to this, the more the advertiser deposits a large amount of service coins, the more the advertiser benefits, so that the demand for service coins is maintained for a long time.

The service coin holding confirmation module 311 is included in the advertising expense account 31 and is a module for checking whether the deposit account 20 holds the service coin. If it is determined that the service coin is possessed, the reward may be remitted by mining altcoin corresponding to the deposit account 20 of a specific advertiser.

The mining information module 312 is included in the advertising expense account 31, requests and receives mining information for a specific altcoin by the mining information tracking module 40, and receives the received mining information in the form of a transaction to the advertising expense account ( 31) refers to a module that is created and stored (memory) and distributed (broadcasted) to a blockchain distributed network so that at least some nodes can share it. According to an embodiment of the present invention, since mining information for a specific altcoin generated by the mining information tracking module 40 configured in OFF-CHAIN is stored in the block chain, advertisements can be performed without an operator acting as an intermediary. An effect that can be driven is generated.

The compensation calculation module 313 is included in the advertising cost account 31, and is generated by the mining information tracking module 40 and is set by the advertiser and mining information that is recorded in the form of a transaction in the blockchain by the mining information module 312. A module that calculates the reward to be remitted to the advertiser's withdrawal account based on a reward condition. According to the compensation calculation module 313 according to an embodiment of the present invention, there is an effect that a mining-based compensation system can be implemented even in a blockchain advertising ecosystem without an intermediary operator. Compensation condition information according to an embodiment of the present invention, like mining information, includes advertisement behavior information such as viewing, clicking, and sharing of the corresponding advertisement, solving a quest in a specific game application, game play time, winning or losing a specific game, etc. Play information, usage information in a specific application, and the like may be included. The advertiser receives the token and service coin of the advertisement fee account 31 through mining, and may be configured to be able to exchange the token and service coin for the corresponding altcoin or other altcoin.

The withdrawal module 314 is included in the advertisement expense account 31 and is a module for remitting altcoins corresponding to the compensation for the advertiser withdrawal account calculated in the compensation calculation module 313 to the advertiser withdrawal account. The transferred altcoin details are created and stored (memory) in the advertising expense account 31 in the form of a transaction, and distributed (broadcast) to the blockchain distributed network to be shared by at least some nodes.

The exchange module 315 is included in the advertisement fee account 31, and when an altcoin held in the advertiser withdrawal account is to be exchanged for a service coin or a specific altcoin, the altcoin to be exchanged from the advertiser withdrawal account It is a module for remittance to the advertising expense account (31). When the altcoin to be exchanged is transferred from the advertiser withdrawal account to the advertisement fee account 31, the service coin or specific altcoin to be exchanged is allocated to the advertiser withdrawal account of the advertisement Dapp.

According to an embodiment of the present invention, a plurality of service coins corresponding to each altcoin may be issued. Accordingly, the advertiser may actively perform mining related to a specific altcoin, and exchange the altcoin obtained through mining for a service coin or a specific altcoin. In the existing blockchain industry, tokens are based on versatility and scalability, but according to the advertising device according to an embodiment of the present invention, abusing that has occurred in the existing advertising market by configuring tokens exclusively and independently for each altcoin This has the effect of preventing and encouraging active consumption and distribution of altcoins.

The code of such a smart contract can be written in the languages of Solidity, Serpent, LLL, and Mutan in the case of Ethereum, for example. Currently, Solidity is mainly used and the syntax is similar to JavaScript. Smart Contract is a program code processed by the processing module 11, including "variables", "structures" and "functions". These Smart Contract Codes can be converted into Byte Codes through the compilation process. Byte code can be compiled through Solidity Realtime Compiler. Solidity's byte codes are all hexadecimal codes, and when Solidity allocates this byte code as Payload (data: ) without a receiving address and distributes a transaction to the blockchain, a block is created by the miner, and these transactions are contract creation It is regarded as a transaction and returns the address of the created (distributed) contract in the contractAddress: field of the Transaction Receipt.

The Smart Contract development environment can include a range including development tools and compilers. For example, in the case of Solidity, when code is written and compiled, all compilers output [Byte Code], [Function Signature], and [ABI].

As described above, the Byte Code is the result of compiling the Smart Contract Code, and when a Contract Creation Transaction is generated and distributed on the Blockchain, when a Message Tx (short for Transaction) to the Contract occurs, Call/Query to the Contract is It runs on top of a distributed ledger device (1, EVM in the case of Ethereum) through the case where it occurs.

FunctionSignature is used as an interface when calling the Contract function, and is a hash value of a 4-byte value obtained by hashing the contract function name with the SHA3 cryptographic hash function.

ABI (Application Binary Interface) refers to an application interface that is described in a way that is not dependent on a specific language or platform. The ABI definition is output by the compiler or ABI Generator, and meta data for Smart Contract functions and parameters are defined in ABI. When you create a JavaScript language-based application with ABI, you can create an object, and simply call the method of the object so that the contract function is called. Currently, Ethereum supports to easily create and use ABI objects in JavaScript applications along with web3.js, and in go-ethereum after 1.4.0, it is possible to easily bind Smart Contracts in Go Native language-based applications. ABIGen that generates code is provided.

This Smart Contract development environment is connected to the Blockchain Engine and can deliver Contract Creation/Deployment, Message Tx, and Call/Query. Such Blockchain Engine means the advertising device 1 according to an embodiment of the present invention, and Ethereum In the example of , it means an Ethereum Node such as geth, parity, or eth. After all, a virtual machine such as EVM for transaction processing and contract execution related to all Smart Contracts is configured on the same node as the advertisement device (1).

In this Smart Contract development environment, ABI can be connected to Applications. Smart Contract has only logic, and an application is required for interaction with advertisers or external systems. Applications such as HTML+CSS+JavaScript, Application Server, and Wallet are, for example, a configuration that interacts with a Smart Contract through an interface with Ethereum.

Smart Contract Code can be largely divided into [Creation/Deployment] [Invoke by Message] [Call]. The code of the advertising expense account according to an embodiment of the present invention may also be divided into advertising expense account creation, altcoin registration message transaction, listing request (Query), and the like.

13 is a schematic diagram illustrating a data structure of deposit account registration transaction information according to an embodiment of the present invention. As shown in FIG. 13 , the memory module 12 according to an embodiment of the present invention may store all or part of a block chain, and in each block header, a hash value (hash) of the previous block header, an answer value ( nonce), the hash value of the transaction group and other information on the time it was created, such as Timestamp (not shown), Difficulty (not shown) indicating the difficulty of mining, and Block Number (not shown) indicating the number of blocks. can Each block body (Contents) may include at least one or more transaction information (in particular, deposit account registration transaction information according to an embodiment of the present invention).

In the advertisement expense account creation transaction information for the generation of the advertisement expense account 31, the address may not be included, and the code (eg, Byte code) of the advertisement expense account which is a kind of smart contract according to an embodiment of the present invention may include When the advertisement expense account creation transaction information is stored in the block and executed, the address of the advertisement expense account, which is a type of contract account for the corresponding smart contract, is created and stored in the block.

When a specific deposit account 20 requests registration for a specific deposit account (message transaction) to the advertising expense account 31, the deposit account registration transaction information is created and stored (memory) and stored in the advertising expense account 31 in the block chain. do. As shown in FIG. 7 , in the deposit account registration transaction information, the altcoin registration execution command (call of the altcoin registration module), altcoin information (eg, IPFS alt) as one of the parameters of the command It may include coin information hash value, reward condition information, management account information in the altcoin block chain), mining condition information, and token information (the maximum number of tokens to be remitted to the advertising expense account to execute advertisements). When the advertising fee account 31 receives the deposit account registration transaction information, it stores it in a block and distributes it globally to the blockchain distributed network so that all nodes of the blockchain distributed network can share the state change by registering a new altcoin.

14 is a flowchart illustrating an altcoin registration method according to an embodiment of the present invention. As shown in FIG. 14 , according to an embodiment of the present invention, an altcoin may be registered in the following steps.

(1) To register a deposit account including altcoin information (image and description, compensation condition information, management account information in the altcoin block chain), mining information, and token information from the advertiser client 200 to the advertisement Dapp 400 send a request

(2) The advertisement Dapp (400) requests the IPFS (410) to store the image and description of the altcoin information.

(3) Return the hash value (image hash value and description hash value) of altcoin information from IPFS (410) to the advertisement Dapp (400)

(4) Request the server 430 to store altcoin information, mining information, and token information including IPFS altcoin information hash value in the advertisement Dapp (400) in the database

(5) Server 420 stores altcoin information including hash value of IPFS altcoin information, mining information, and token information in DB 430

(6) Send a message transaction to store altcoin information, mining information, token information, etc. including IPFS altcoin information hash value in the advertising Dapp (400) in the block chain (30)

By the above steps, various advertisement systems can be implemented on the block chain including the advertisement expense account according to an embodiment of the present invention. According to this, regardless of the type of altcoin or the type of advertisement Dapp, the supply and use of advertisements through the integrated account is possible.

15 is a schematic diagram illustrating a data structure of withdrawal transaction information according to an embodiment of the present invention. 15, the memory module 12 according to an embodiment of the present invention can store all or part of the block chain, and each block header includes a hash value (hash) of the previous block header, an answer value ( nonce), the hash value of the transaction group and other information on the time it was created, such as Timestamp (not shown), Difficulty (not shown) indicating the difficulty of mining, and Block Number (not shown) indicating the number of blocks. can Each block body (Contents) may include at least one or more transaction information (particularly, withdrawal transaction information according to an embodiment of the present invention).

When a specific altcoin is mined in the advertiser client connected to the advertiser withdrawal account 32, the token is transferred from the advertisement expense account 31 to the advertiser withdrawal account 32 according to the set compensation criteria, When a withdrawal request is sent (message transaction), withdrawal transaction information is created and stored (memory) and stored in the advertising expense account 31 in the block chain.

As shown in FIG. 9 , in the withdrawal transaction information, advertisement fee account address information, (eg, IPFS altcoin information hash value, reward condition information, management account information in the altcoin block chain) and mining condition information, token may contain information. When the advertising expense account 31 generates withdrawal transaction information, it is stored in memory and distributed globally to the blockchain distributed network, and withdrawal transaction information is recorded in all nodes of the blockchain distributed network. State changes can be shared.

16 illustrates a method for requesting an altcoin reward according to an embodiment of the present invention. As shown in FIG. 16 , according to an embodiment of the present invention, compensation according to the altcoin of the altcoin may be requested in the following steps.

(1) Mining for a specific altcoin through the advertisement Dapp (400) in the advertiser client (320)

(2) After receiving the altcoin image information and description information from the server 420 from the advertisement Dapp(400), it is converted into a hash value (altcoin information hash value)

(3) Sending mining information (in the form of message transaction) including altcoin information hash value to the advertising fee account (Smart Contract) of the block chain 30 from the advertisement Dapp (400)

(4) The advertisement fee account, which is a smart contract stored in the block chain 30, searches the deposit account registration transaction with the altcoin information hash value (verifies the integrity of specific altcoin information through the search or failure of the altcoin information hash value)

(5) After receiving the mining information, calculating the number of tokens corresponding to the reward based on the mining information and the reward condition information, creating a withdrawal transaction and distributing it to the blockchain distributed network

When the advertising system is implemented as a block chain, there is a problem that an attempt to exploit altcoin rewards may occur through falsification of altcoin mining results. However, according to each of the above steps according to an embodiment of the present invention, since the DB, IPFS, and the block chain have an interdependent relationship, if the DB is tampered with, the effect that the Dapp is not executed occurs.

17 is a flowchart illustrating a distributed ledger method for advertising according to an embodiment of the present invention. As shown in Fig. 17, the distributed ledger method (advertising method) for advertisement of the processing module 11 according to an embodiment of the present invention includes a deposit account registration step (S10), a service coin holding confirmation step (S11) , it is possible to process transaction information, including the mining information receiving step (S12), the reward calculation step (S13), the withdrawal step (S14), and the altcoin exchange step (S15).

The deposit account registration step (S10) is a step in which the deposit account is registered in the advertisement Dapp or block chain through an advertisement registration request to the advertisement fee account. At least one account is created for each advertiser by this step.

The service coin holding confirmation step (S11) is a step of confirming whether the deposit account has the service coin in the advertising expense account. By S11, only advertisers who have service coins in the advertising expense account can be configured to advertise specific advertisements in the advertisement Dapp.

The mining information receiving step (S12) is a step of transmitting the mining information of a specific advertiser to the advertising cost account in the mining information tracking module.

The compensation calculation step (S13) is a step of calculating a compensation based on the mining information and the compensation condition information in the advertisement expense account.

In the withdrawal step (S14), a transaction for altcoin compensation request is created in the advertisement fee account 31, and for the remittance of altcoin corresponding to the compensation, it is stored in the storage or memory of the advertisement fee account 31 is a step A contract account can contain persistent storage called storage. In storage, a 32-byte key is mapped to a 32-byte value in a key-value map structure. A specific Smart Contract may not be able to read or write the storage of a contract other than itself. Memory can be configured as a space where Smart Contract can obtain the latest instance whenever there is a message call. Memory can be read and written at the byte level, but it can be stored in 32-byte chunks. That is, if a value of 1 is stored in memory, it can be stored in a 32-byte (256-bit) space. For example, the EVM includes a stack that can contain a total of 1024 instruction sets (OPCODEs), and can have a 256-bit word (value). Thereafter, the advertisement device 1 distributes and broadcasts withdrawal transaction information, which is a changed state, to all nodes of the blockchain distributed network 100 .

The altcoin exchange step (S15) is a step in which the advertiser exchanges an altcoin for another specific altcoin. A specific altcoin according to an embodiment of the present invention may be configured to be able to exchange only altcoins related to the corresponding advertisement and mining. According to an embodiment of the present invention, when only altcoins related to advertisements and mining of the altcoin are configured to be exchangeable, only genuine customers of the altcoin are exposed to the advertisements of the altcoin and abusing is reduced. do.
