Description

Blockchain-based remittance method and system using it {BLOCKCHAIN-BASED REMITTANCE AND COLLECTION METHOD AND SYSTEM USING THE SAME}

The present invention relates to a method for implementing a blockchain-based remittance platform and a system using the same. More specifically, it relates to a blockchain-based remittance method and a system using the same, which easily finds an electronic wallet address or a smart contract address through keyword search, and has both user convenience, reliability, and security.

Bitcoin is the first generation of blockchain technology that introduces a peer-to-peer system of distributed ledgers, which is free from the management of a central server through a new cryptocurrency. Ethereum, which provides a distributed computing platform for implementing Smart Contract) functions, is the second generation of blockchain technology. Ether, provided by Ethereum, is traded as a type of cryptocurrency in cyberspace, like Bitcoin, and is the most representative altcoin and blockchain platform.

Blockchain platform allows members (nodes) participating in the system to distribute and store data on their computers, making it virtually impossible to tamper with or alter data (reliability), and members can each hold distributed information (transparency). , It has the characteristic that it does not require a separate central server administrator.

It contains user information and cryptographic keys for storing, sending/receiving, and transacting cryptocurrencies linked to such blockchain technology, and the implementation of this is a blockchain-based electronic wallet.

Such a blockchain-based electronic wallet uses a public key in a public key cryptosystem as an account number in a bank account, and a corresponding private key as the password for the account. .

In this case, when the complex hash function password of the public key and the private key is applied and used as it is, the public key such as the user's address cannot be easily searched or recognized by the other party, so the transaction accessibility of the general public is very low, and it is difficult to read.

Therefore, there is a need for a blockchain-based remittance platform that can easily find an e-wallet address or a smart contract address through a keyword search function and solve the reliability and security problems that may occur due to the provision of the search function.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The configuration of the present invention and its effect will be clearly understood through the detailed description below.

1 is a conceptual diagram of a block chain-based remittance system according to an embodiment of the present invention.

In the sender account 110, instead of the sender account 120 and the receiver account 130, an account means the entity and basic unit of executing all transactions or transactions, and is an electronic wallet or It can be composed of a smart contract. In addition, depending on the transaction role, it can be divided into the sender account 110, which is the subject of remittance, the sender account 120, instead of the subject of remittance, and the receiver account 130, which is the subject of remittance. Its role can be different.

Each node that installs and executes such an account may form a network of a peer to peer (P2P) structure operated according to a block chain algorithm through the network 140. Here, the network 104 is, for example, the Internet, one or more local area networks (LANs), wide area networks (WANs), cellular networks, mobile networks, and low power wide area networks (LPWANs). ), etc. may be a wired or wireless network.

In addition, as shown in Figure 1, the sender account (account) 110, instead of the sender account 120 and the receiver account 130 may each be configured as a smart contract (contract). Here, a smart contract refers to a digital contract in which contract conditions are set based on blockchain technology and the contract contents are fulfilled when the conditions are met, and is a kind of automated contract system. In cryptocurrency, various benefits or contract terms contracted with affiliates or related companies can be stored in the form of smart contracts, and users can apply new contract terms to cryptocurrency in an electronic wallet and pay them to counterparties.

For example, when a transaction is conducted according to a smart contract related to content, music album, concert, etc., cryptocurrency can be automatically delivered to composers, lyricists, sessions, and singers related to the contract according to predetermined rules without intermediaries. Even between smart contracts, remittances can be automatically processed according to the set reservation conditions.

In addition, the block chain-based remittance system according to an embodiment of the present invention includes a remittance account 120 instead of designated in connection with the remittance account 110, and when remittance is requested on behalf of the remittance account 110 Instead, at least a part of the remittance amount may be remitted in the remittance account 120. In addition, when requesting a remittance by the remittance account 110 instead, the remittance account 120 instead selects any one of re-request such as accepting, rejecting or changing the remittance amount, and the selected content is the remittance account ( 110).

For example, when transacting through Ether, a cryptocurrency used in Ethereum, when it is necessary to remit 10 Ether to the receiver account 130, transfer only 3 Ether, which is the amount remittable from the sender account 110 , The insufficient amount of 7 Ether may be requested to be remitted through the sender account 120 instead of designated. Instead, the sender account 120 may be composed of two or more electronic wallets.

In such a blockchain-based remittance platform, if an e-wallet address or smart contract address can be easily found through keyword search, information asymmetry and information gap between recipients and senders can be resolved, contributing to the activation of related networks. .

2 is a block diagram illustrating a block chain-based remittance system using keyword search according to an embodiment of the present invention. In FIG. 2, only one verification node 100, a receiver node 200, and a receiver account 210 are shown for simplicity of explanation, but the sender account 210 exists in each of the plurality of receiver nodes, and thus a plurality of It is configured, and the verification node 100 may also be composed of two or more nodes. In addition, here, the sender node 200 is a subject executing the sender account 210, and may include at least one of various electronic devices or processing devices such as a computer, a smartphone, a tablet computer, a mobile communication device, a computer server, etc. I can.

The verification node 100 serves to manage and verify a plurality of remittance accounts 200 constituting a blockchain network capable of keyword search, and the remittance account 210 is as shown in FIG. Depending on the entity related to remittance or collection, it may be a sender account 100, instead a sender account 120, or a receiver account 130, and the role may vary according to each type of remittance transaction. In addition, the sender account 210 may be configured in the form of a smart contract.

First, the receiver account 210 is a private key generation unit 201 for generating and issuing a private key, a public key generation unit configured to generate a public key generated through the private key ( 202) may be included. The pair of the private key and the public key generated as described above may be stored in the sender account 210. In this case, when the remittance account 210 is in the form of a smart contract, the private key generation unit 201 may not be included.

In addition, the sender account 210 may include an address generator 203 configured to hash the public key or generate an address unique to each account in another way. For example, on the Ethereum platform, the address of an electronic wallet or smart contract may be generated in a fixed arrangement of 20 bytes.

In addition, the remittance account 210 may include a metadata generator 204 configured to generate a mapping with its own address or metadata corresponding to the address, and the metadata generated by mapping with the address may include an index ( By performing the role of index), a keyword search of the address of the sender account 210 is possible.

For example, metadata is attribute information that is given by distinguishing between an official node or a nonofficial node through a proof in the blockchain system, or at least one freely generated by the sender account 210 It may be hash tag information, or may be hash tag information related to attribute information of a public node selected from an unauthorized node. Here, a hashtag is a form of metadata to provide a convenient search function so that you can easily find content containing a specific topic or content in a social network service (SNS) or microblog. In general, a # sign and a specific word are attached. Express. The verification structure and metadata display method of the authorized node and the non-authorized node will be described later with reference to FIGS. 3 and 4.

On the other hand, the verification node 100 may be composed of only approved specific nodes among a plurality of nodes constituting a block chain network, and may be composed of one or more nodes. Accordingly, there is no need for all nodes to participate in verification, so the speed of management and verification processing is fast.

Here, the verification node 100 processes the address mapping processing unit 101 configured to map metadata to the address of the sender account 210 and the address of at least one electronic wallet through keyword search using metadata. It may include a keyword search processing unit 102.

Further, the verification node 100 may include a verification processing unit 103 configured to verify whether a condition for mapping metadata to the address of the sender account 210 is satisfied. Here, the verification method may use various conventionally known verification methods such as PoW (Proof of Work, proof of work), PoS (Proof of Stake, proof of stake), or PoC (Proof of Concept). Since metadata is mapped to the address of the sender account 210 after such a verification procedure, it is possible to improve the reliability of search information from the user's point of view.

In addition, the verification node 100 displays metadata processing so that information related to the metadata of the public node and the information related to the metadata of the non-authorized node are displayed differently from each other when searching for a keyword of the address of the sender account 210 It may further include a processing unit.

According to the above-described address-metadata mapping processing and different display processing of metadata, the metadata mapped to the address of the sender account 210 enables keyword search and thus not only for the purpose of quickly finding an address, but also for verification. By achieving the purpose of distinguishing and expressing the designated authorized node and the general non-authorized node, it is possible to provide a blockchain-based remittance system using keyword search that can maintain both the convenience and reliability of user search.

3 is an exemplary diagram for explaining a method of verifying an official node and assigning public metadata according to an embodiment of the present invention.

Authorized node means a node that has been officially recognized or verified by the blockchain system. For example, as shown in Fig. 3, entertainment agencies, affiliated teams or groups, affiliated singers, official fan clubs, etc., which specifically require search reliability in the blockchain network between music creators and fans, are designated as authorized nodes to secure authenticity and reliability. Can be.

As shown in FIG. 3, the verification of the authorized node may be performed based on a hierarchy structure. For example, the node 320 of BTS, a singer belonging to the node 310 of Big Hit Entertainment, an entertainment agency. ), verification can be performed from the node 320 of the BTS (BTS) to the singer's node 330 or the ARMY node 340 of the official fan club, and mapped to the electronic wallet address of the official node accordingly Depending on the hierarchical structure, the metadata information can also have a tree-type structure such as (company)-(group)-(singer affiliated, official fan club).

When the verification processing unit 103 of the verification node 100 recognizes as an authorized node through verification, it is possible to map public metadata related to the public name information to the electronic wallet address of the corresponding public node through the address mapping processing unit 101, and this Metadata information related to the same public node is not generated freely in the node, but is determined by consensus on the blockchain system.

In addition, as shown in FIG. 3, the name or identification information corresponding to the e-wallet address of the public node can be distinguished from the non-authorized node and marked with a predetermined mark such as a star in front of the name to indicate that it is a public node. In addition, such a classification display can give authenticity and reliability when searching for a user's keyword.

4 is an exemplary diagram for explaining a method of verifying a nonofficial node and assigning non-authorized metadata according to an embodiment of the present invention.

Referring to FIG. 4, the node 320 of BTS, which is an authorized node, and the node 340 of ARMY, and non-authorized nodes, such as the nodes of fans (410, 420, 430). Verification between, or verification between unauthorized nodes, for example, a verification structure between the node 410 of fan 1 and the node 411 of fan 4 is disclosed, and is represented by a hierarchical structure of, for example, three tiers. I did.

The official nodes 320 and 340 associated with the official fan club or group may be located in Tier 1, and the non-authorized nodes 410, 420 and 430 composed of a plurality of fans may be located in Tier 2. . At this time, the verification processing unit 103 of the verification node 100 is based on the past transaction or activity between the unauthorized node (410, 420, 430) and the authorized node (320, 340), the non-authorized node 410, 420, It may be determined whether to map information related to metadata of the public nodes 320 and 340 to the address of the electronic wallet 430. For example, if the node 410 of fan 1 has previously performed a transaction activity such as sending/receiving money with the node 340 of ARMY, as metadata of the electronic wallet of the node 410 of fan 1, “ If a hashtag such as "#ARMY" can be used, and in the case of fan 2's node 420, if there has not been a transaction activity such as remittance or transfer with the node 340 of ARMY before, As the metadata of the electronic wallet of the node 420 of Fan 2, a hash tag that can be arbitrarily designated can be used, but the same as the metadata of the node 340 of ARMY, an official node (ARMY)” can be disabled as a hashtag.

In addition, in the case of the fan 3 node 430, the transaction activity was conducted with both the node 340 of the ARMY and the node 320 of the BTS. “#ARMY #BTS (BTS)”, it is possible to map a hashtag of the same name as the metadata of two public nodes to metadata. That is, metadata may be generated by mapping a plurality of hashtags or attribute information to each node.

In addition, in the case of the node 411 of Fan 4 located in Tier 3, a transaction activity was performed with both the node 340 of ARMY and the node 320 of BTS, which is an authorized node. However, if there is a transaction activity with the node 410 of fan 1 of tier 2, the same metadata as "#ARMY", which is the metadata of the electronic wallet of the node 410 of fan 1, can be used. It is also possible to set. In other words, even in the case of a non-authorized node without direct transaction activity with an authorized node, information related to the metadata of the authorized node may be made available as metadata according to whether or not there is a transaction activity between the authorized node and an unauthorized node that has transaction activity. I can.

In this way, by mapping the address of the electronic wallet to metadata to enable keyword search, a network based on a block chain can be activated between music creators and fans or between multinational fans. In addition, as shown in FIG. 4, the method of displaying information related to the metadata of the authorized nodes 320 and 340 is to display an asterisk in front of the name, and the non-authorized nodes 410, 411, 420, 430 In a method of displaying information related to the metadata of, it is possible to maintain the reliability of the authorized node by displaying different marks such as # (hash tag) in front of the name.

5 is a flowchart illustrating a method of performing a block chain-based remittance using a keyword search according to an embodiment of the present invention.

According to an embodiment of the present invention, in order to reinforce the security function, the password of the electronic wallet may be set through the ear-ear sound recognition in the process of generating the private key (S510). The user transmits a voice signal through an external microphone. Instead of receiving, it is possible to set and input a password through a user's own biometric recognition by recognizing a voice signal transmitted to the inside of the ear through the inside of the face through the microphone built into the earphone or the earphone. When a user is wearing earphones or earphones, it is more intuitive and natural to log-in authentication of an electronic wallet, and because hacking is difficult because it does not recognize a voice signal transmitted to the outside, it is possible to increase security.

Next, a private key may be generated in the sender account 210 (S520), a public key may be generated based on the private key, and an address of the electronic wallet may be generated (S530). The address of the electronic wallet is the public key. The address can be generated by hashing, or through other methods without using the public key. The pair of the private key and the public key generated in this way may be stored in the electronic wallet.

Next, metadata mapped to the address of the electronic wallet may be generated and processed. (S540) The remittance account 210 is mapped with its own address through the above-described verification of a public node or verification of a non-authorized node. Alternatively, it is possible to create corresponding metadata, and the generated metadata serves as an index to enable keyword search of the electronic wallet address.

Accordingly, by providing a keyword search using metadata mapped to the address of the electronic wallet (S550), the user solves the problem of obfuscation caused by the address of the complex electronic wallet, and conveniently searches the address of the electronic wallet as in web keyword search. Can be done. In addition, as a result of keyword search, metadata-related information of an authorized node and metadata-related information of an unauthorized node are displayed so that they can be differentiated from each other, so that a user who is a search subject can trust the authorized node in the search result.

Next, the user can more conveniently perform remittance by using the electronic wallet address searched through keyword search (S560).

As described above, the block chain-based remittance method and system according to the embodiment of the present invention have been described as specific various embodiments, but this is only an example, and the present invention is not limited thereto, and according to the basic idea disclosed herein It should be construed as having a range of. A person skilled in the art may combine and replace the disclosed embodiments to implement a pattern of a shape not indicated, but this also does not depart from the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on the present specification, and it is clear that such changes or modifications also belong to the scope of the present invention.
