Description

Advertisement apparatus and method using advertisement module included in application}

The present invention relates to a blockchain-based advertisement device and method using an advertisement module included in an application.

In early 2018, as Bitcoin became stagnant, demand for altcoins began to rise considerably. Here, alt-coin (Alt-coin) means 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 major altcoins. Until March 2017, Bitcoin's market share of all cryptocurrency markets reached 85%. However, with the rise of altcoins, including Ethereum, Bitcoin's share fell sharply to reach 36% in early 2018.

However, it is still very difficult for many people to purchase such altcoins. First, you have to pay for having altcoins. It is difficult for the majority of the public to invest real money in a digital asset that is still unfamiliar, and because of this, the prevalence of altcoins remains around 1-2% of the total internet access population. And even if you purchase altcoins, you can open an electronic wallet account to manage public and private keys and participate in ICO, how to trade altcoins at various cryptocurrency exchanges after going through tight KYC procedures, and using expensive GPUs. It is difficult for the general public to easily proceed with the method of mining altcoins by purchasing and selecting the appropriate mining pool. In addition, there was a barrier to purchasing altcoins because of the high risk of loss of investment due to very high price volatility.

Due to the high barriers to entry for the advertiser's altcoin, despite the great advantage of executing the advertisement cost with the altcoin and paying to the advertisers, the advertisement is executed with the altcoin rather than the legal currency from the general advertiser's point of view. And it was very difficult to pay (withdraw).

Moreover, it was very difficult for altcoin developers to promote and sell their altcoins. Only a few of the advertisers have access to altcoins, the demand is concentrated only on the top 1% altcoins, and it became difficult to promote ICO ads on major advertising platforms such as Google / Facebook. . In addition, it is difficult to secure the initial advertiser for altcoin and secure the initial use. After all, it has become very difficult to create and secure Altcoin's distribution system and price system.

Can be.

(1) Service coin deposit stage

Advertiser's deposit account by purchasing a service coin for advertisement of altcoin (advertisement including altcoin airdrop, altcoin bounty, altcoin reward, etc.) or advertiser who advertises a specific altcoin at the advertisement fee from advertiser client It is a stage to hold on. The service coin is obtained by an advertiser buying from cryptocurrency exchanges in fiat currency or other cryptocurrency or by trading in P2P. In this step, transactions corresponding to a change in the status of a certain number of service coins to a deposit account configured in the blockchain of the service coin are distributed and recorded in the blockchain of the service coin.

According to another embodiment of the present invention, the advertising service entity may own a deposit account. In this case, in this step, the service coin remittance transaction including a remittance request for remitting a specific number of service coins from the service coin advertiser account, which is the account of the blockchain of the service coin included in or connected to the token management module of the advertisement device, to the deposit account is serviced. It will be distributed and recorded on the coin's blockchain.

(2) Steps for providing advertising rights

In the token management module, the advertiser's service coin that is deposited in the deposit account is checked, and the advertisement service authority for the altcoin remitted by the advertiser client or the altcoin to be remitted in the future is granted. After the service coin of the deposit account is confirmed by the token management module, the advertiser can use the advertising service by freely remitting the specific alt coin to be executed to the advertising cost account.

(3) Altcoin Remittance Stage

This is a step in which the advertiser client creates an altcoin remittance request, which is a request for remittance from the advertiser account of the altcoin blockchain to the advertisement cost account, and distributes and records the altcoin remittance transaction, a transaction including the altcoin remittance request, to the altcoin blockchain. . In this step, the token management module can generate the advertisement token used in the advertisement module by offchain by checking the altcoin remittance transaction or checking the altcoin holding status of the advertisement cost account. The advertisement token according to an embodiment of the present invention does not incur excessive costs incurred in the recording of the blockchain, and an effect of promoting the advertised action is generated.

Alternatively, according to another embodiment of the present invention, the advertisement token can be pegged 1: 1 with the legal currency, and the state change of the advertisement token can also be distributed to the blockchain and stored in a record / web server. According to this, when the reward is accumulated to the advertiser, the reward can be accumulated on the basis of the legal currency, and finally, the effect of withdrawing the alt coin according to the unit price at the time of withdrawal request is generated.

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

(4) Advertising condition setting step

This is a step in which the advertiser client sets advertisement conditions desired by the advertiser and transmits the generated advertisement condition information to the advertisement management module. Advertisement condition information according to an embodiment of the present invention may include personal information such as gender, age, region, occupation, educational background, information related to application use, information about an advertisement, and the like.

(5) Mining stage

This is a step in which the advertiser executes a specific application in the advertiser client and performs the advertisement action to perform mining of the advertisement token and generate mining information, which is information about mining, in the advertisement module. The mining may refer to a predetermined advertisement action such as viewing an advertisement, executing an application, performing a specific quest, and sharing an altcoin posting.

(6) Step of receiving mining information

The advertisement module is a step of transmitting mining information to the mining management module and receiving the mining information of the advertiser in the mining management module.

(7) Advertising token allocation stage

The token management module is a step of receiving mining information from the mining management module and assigning the advertisement token generated in (4) to the advertiser based on the mining information. At this time, if there is predetermined compensation condition information by the advertiser client, an advertisement token may be assigned based on mining information and compensation condition information. According to an embodiment of the present invention, after the statutory currency value of the advertisement activity by the mining is determined, the advertisement token may be allocated off-chain according to the determined value of the advertisement activity.

Alternatively, according to another embodiment of the present invention, the advertising token can be pegged 1: 1 with the legal currency and the state change of the advertising token can also be distributed and recorded on the blockchain. According to this, when the reward is accumulated to the advertiser, the reward can be accumulated on the basis of the legal currency, and finally, the effect of withdrawing the alt coin according to the unit price at the time of withdrawal request is generated.

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

(8) Altcoin withdrawal request step

In the advertisement module of the advertiser client, when an altcoin withdrawal request is sent to the token management module or a predetermined specific condition (for example, a minimum withdrawal unit) is satisfied, the token management module determines the value of the advertisement token (the present invention According to one embodiment, the corresponding altcoin and peg, or peg in legal currency according to another embodiment of the present invention) and other altcoins (such as the representative value of a specific exchange or the average value of multiple exchanges) are paid to the advertiser A transaction that includes a withdrawal request, which is a remittance request for determining the amount of a specific altcoin to be made and remitting the specific altcoin in which the payment amount is confirmed from the advertisement cost account to the altcoin withdrawal account of the advertiser on the same blockchain. It is a step of creating, withdrawing, and distributing transactions on the blockchain.

At this time, the advertiser withdrawal account according to an embodiment of the present invention is generated by the advertisement module, and along with the creation of the altcoin withdrawal request, the advertisement module outputs a pair of a private key and a public key to provide a password for the advertiser's application. Alternatively, the private key may be encrypted using personal identification information such as the fingerprint information of the advertiser, and key store data may be generated based on the encrypted private key.

According to an embodiment of the present invention, since the creation of the withdrawal account of the advertiser needs to be performed before the request for withdrawal of the altcoin from the client of the advertiser, the advertiser actually uses the altcoin account on the blockchain until the request for withdrawal of the altcoin Even if it is not configured, the effect of using altcoin is generated.

Through the above steps, the effect of improving accessibility to the cryptocurrency of the advertiser is generated. According to an embodiment of the present invention, an advertiser who wants to use a cryptocurrency or want to take advantage of the increase in the value of the cryptocurrency without any prior knowledge of the cryptocurrency (for example, to create a wallet in the ether-wallet, private key There is a concept that a certain alt coin can be acquired in a conventional manner (advertisement viewing, gameplay, specific quest execution, posting sharing).

For example, an application advertiser including an advertisement module has the same effect as holding an altcoin by assigning an advertisement token that is pegged 1: 1 to one without creating an advertisement cost account. According to an embodiment of the present invention, when an app advertiser wants to withdraw the altcoin, the ad withdrawal account is created at any time to perform the withdrawal of the altcoin as much as the advertisement token assigned to the advertiser's account in the advertisement module. Can be.

In addition, when an altcoin withdrawal request is received, the advertisement module outputs a private key and a public key pair to encrypt the private key using a personal identification information such as a password for the application of the advertiser or the fingerprint information of the advertiser, Key store data is generated based on the private key. Thereafter, the token management module transmits the specific alt coin 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 cost account. Subsequently, when the corresponding advertiser wants to access the withdrawal account of the advertiser, the key storage information is generated in the advertiser client by the advertisement module, so the advertiser can enter the personal identification information such as the password or the fingerprint information of the advertiser only. This has the effect of being able to access the withdrawal account. In addition, since the generated private key is directly encrypted by the personal identification information and stored in the advertiser's client, an effect that the advertisement device does not store the private key occurs. By generating key storage information according to an embodiment of the present invention, an attacker must additionally find personal identification information of an advertiser in order to obtain a private key, and personal identification information without using a complicated private key The effect of using the service with only the key storage information is generated.

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

(1) Algorithm information used for private key encryption (e.g. bi-directional encryption algorithm, e.g. AES algorithm)

(2) Variables required for the private key encryption algorithm

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

(4) Algorithm information used to encrypt personally identifiable information (e.g., one-way encryption algorithm, e.g. Scrypt algorithm)

(5) Variables required for personal identification information encryption algorithm

(6) (2) for verification of personal identification information when using key storage information and hash value of encrypted personal identification information

In the above step (4), for example, if Scrypt is used, it is designed to have a memory overhead when generating the result value, which has the effect of making brute-force attacks difficult.

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

(1) The application module of the advertiser withdrawal account is received from the application module of the client. According to an embodiment of the present invention, the request for creating an account for withdrawal of an advertiser is accompanied by an information disclosure request or an altcoin withdrawal request requesting information disclosure of statistical information of an advertiser based on the personal information of the advertiser It can be generated in the advertisement module and transmitted to the advertisement device.

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

(3) Key storage information is generated by encrypting the private key based on the personal identification information such as the password or fingerprint information of the advertiser. With this key storage information, the advertiser does not need to memorize the private key or always carry it, and it is possible to access the withdrawal account of the advertiser and digital signature of the request for withdrawal of altcoin only by entering personal identification information. Is generated.

(4) The advertisement module transmits the generated public key to the advertisement device.

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

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

(7) When the verification of the signature is confirmed, the token management module may create a withdrawal transaction including a withdrawal request for the altcoin to be withdrawn from the advertisement cost account to the withdrawal account of the advertiser, and distribute and record it on the blockchain.

By the above steps, the advertiser does not fall into the problem of creating a wallet or storing the private key through a difficult procedure, and until the withdrawal, the advertiser is very simple to use altcoin in an existing manner rather than on-chain. An effect is made available to the client.

(2) The advertiser withdrawal account is updated in the advertisement module included in the 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 generate a new wallet address for every application, and an effect is that the advertisement token can be managed in an integrated manner for all applications.

(3) The advertiser performs predetermined mining according to a specific alt coin or a specific application, such as watching an advertisement output by the advertisement management module or playing a game.

(4) The advertisement module tracks mining to generate mining information, 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, and time information is generated and transmitted to the mining management module.

(5) The token management module allocates as many advertisement tokens to the advertiser as it corresponds to mining information. 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 mining is determined, the token management module may allocate the advertiser's advertisement token to the advertiser.

(6) The advertiser signs and sends the withdrawal request for the altcoin with a private key.

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

(8) When the signature is verified, the token management module creates a withdrawal transaction including a withdrawal request for withdrawing the requested altcoin from the address of the advertisement account to the advertiser's withdrawal account, and distributes it to the blockchain , Record.

By the above steps, the advertiser can use altcoins without generating and holding wallets and private keys separately for each altcoin, and can obtain and use altcoins by using simple methods such as watching advertisements without using any cash. There will be. The advertiser can move the altcoins thus obtained to other exchanges to make profits or conduct transactions.

As shown in Fig. 9, an advertisement system using a blockchain according to an embodiment of the present invention avoids attempting to take rewards (advertising tokens or altcoins themselves) through deposit accounts and advertisements for specific advertisements. It may be composed of an advertiser withdrawal account, an advertisement Dapp, which is an advertisement channel through which advertisements are distributed, and one blockchain 30 and IPFS 410 connected to a plurality of Dapps. According to this configuration, advertisers for advertisements can register and execute advertisements in an integrated form in various advertisement applications, and advertisers use one account (EoA or CA) to integrate advertisements in multiple advertisement applications. The effect of being able to request compensation occurs.

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

The advertiser client 200 refers to a client, such as a smartphone, PC, node, etc., for an advertiser who wants to advertise or distribute a specific advertisement in the advertisement Dapp to use the advertisement decentered application (Dapp).

The advertiser client 320 refers to a client, such as a smartphone, PC, node, etc., of an advertiser who wants to receive compensation (advertising account token or altcoin itself) by mining the alt coin registered in the advertisement.

The advertisement Dapp 400 refers to 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 (the weight of web3js is large). Advertiser client 200 and advertiser client 320 will interact with blockchain 30, IPFS 410, nodeJS server 420 through this front-end application.

IPFS (InterPlanetary File System) is a peer-to-peer distributed file system that tries to connect all computing devices to the same file system. It can also be viewed as a single BitTorrent swarm (a unique identifier of the file and a list of the peers that own the file) exchanging objects in the Git repository. That is, IPFS provides a content-addressed block storage model with high throughput by using a content-addressed hyperlink that uses the hash value of the Cotent as an address. It can take the form of a generalized Markle DAG, a data structure capable of building versioned file systems, blockchains, and permanent web pages. IPFS is a combination of a distributed hash table, an incentived block exchange, and a self-authenticating namespace. When using IPFS, a single point of failure is not caused by unexpected termination or destruction of a specific node, and each node has an effect of not having to trust each other. According to an embodiment of the present invention, when an advertiser registers Altcoin, a product to be advertised, in the advertisement Dapp 400 for advertisement, the front-end advertisement Dapp 400 provides IPFS (image file and description) for the altcoin. After uploading to 410), the hash of the uploaded file is stored in the blockchain 30 and DB 430.

The code of this smart contract can be written in the languages of Solidity, Serpent, LLL, and Mutan, for example, in the case of Ethereum. Currently, Solidity is mainly used, and the syntax is similar to JavaScript. Smart Contract is 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 Compile process. Byte code can be compiled through Solidity Realtime Compiler. Byte code of Solidity are all hexadecimal codes, and when Solidity allocates this Byte code as Payload (data:) without receiving address, and distributes the transaction on the Blockchain, a block is created by Miner, and these transactions are created by Contract Creation It is regarded as Transaction, and returns the address of the created (distributed) Contract in the contract Address: field of Transaction Receipt.

The smart contract development environment can include a range including development tools and compilers. For example, in the case of Solidity, if you write and compile code, all compilers output [Byte Code], [Function Signature], and [ABI].

Byte Code is the result of compiling Smart Contract Code as described above, and when creating and distributing a Contract Creation Transaction on Blockchain, when Message Tx (short for Transaction) to Contract occurs, Call / Query to Contract It runs on a distributed ledger device (1, EVM for Ethereum) through the occurrence.

FunctionSignature is used as an interface when calling the Contract function, and is a Hash value of a 4-byte value that hash the Contract function name as a SHA3 cryptographic hash function.

ABI (Application Binary Interface) means an application interface described in a way that is not dependent on a specific language or platform. The ABI definition is output by the compiler or the ABI Generator. In the ABI, meta data for functions and parameters of the smart contract is defined. When you create a JavaScript language based application with ABI, you can create an object and easily call the method of the object so that the contract function can be called. Currently, Ethereum supports easy creation and use of objects in ABI in JavaScript applications with web3.js, and in Go-ethereum since 1.4.0, it is possible to easily bind Smart Contract in Go Native language based applications, and ABI based Go It provides ABIGen that generates codes.

When implementing the advertising system as a blockchain, there arises a problem that an attempt to exploit the altcoin reward through modulation of the altcoin mining result may occur. However, according to each of the above steps according to an embodiment of the present invention, since DB, IPFS, and blockchain have interdependencies, when the modulation of DB occurs, the effect that Dapp is not executed occurs.

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

The deposit account registration step (S10) is a step of registering the deposit account to the advertisement Dapp or blockchain through an advertisement registration request to the advertisement cost account. At this stage, at least one account is created for each advertiser.

The service coin holding confirmation step (S11) is a step of checking whether the deposit account has a service coin in the advertisement cost account. By S11, only advertisers holding the service coin of the advertisement cost account may be configured to advertise a specific advertisement in the advertisement Dapp.

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

The reward calculation step (S13) is a step of calculating a reward based on mining information and reward condition information in an advertisement cost account.

In the withdrawal step (S14), the transaction for the altcoin reward request is generated in the advertisement cost account 31 and stored in the storage or memory of the advertisement cost account 31 for the transfer of the altcoin equivalent to the reward. It is a step. The contract account may contain a persistent storage called storage. In storage, a 32-byte key is mapped to a 32-byte value in a key-value map structure. Certain smart contracts may not be able to read or write storage of contracts other than themselves. Memory can be composed of a space where the smart contract can get the latest instance whenever there is a message call. In memory, it can be read and written at Byte level, but it can be stored as a 32-byte chunk. That is, in the memory, a value of 1 can be stored in a space of 32 bytes (256 bits). For example, EVM includes a stack that can contain a total of 1024 Instruction Sets (OPCODEs) and can have 256 bits of word (value). Subsequently, the advertisement device 1 distributes the withdrawal transaction information in the changed state to all nodes of the blockchain distributed network 100 and broadcasts it.

The altcoin exchange step (S15) is a step in which the advertiser exchanges altcoin for another specific altcoin. Certain altcoins according to an embodiment of the present invention may be configured to exchange only altcoins related to the advertisement and mining. According to an embodiment of the present invention, when only the alt coin associated with the advertisement and mining of the alt coin is configured to be exchanged, only the true customer of the alt coin is exposed to the advertisement of the alt coin and the effect of reducing abusing occurs do.
