How to provide real estate security transaction using blockchain ledger system{METHOD OF PROVIDING REAL ESTATE INFORMATION FOR SAFE TRANSACTION USING DIGITAL LEDGER WITH BLOCK CHAIN SECURITY TECHNOLOGY}

The present invention relates to a method for providing a real estate security transaction, and more particularly, to a method for providing a real estate security transaction using a blockchain ledger system for preventing false sale.

Block chain technology is introduced as a security system used to be used for transactions using cryptocurrencies, but is not limited to cryptocurrency transactions.

A blockchain transaction ledger can be understood as a collection of'chains' that follow'blocks' containing transaction information. Blockchain refers to a data distribution processing technology in which all users participating in the network are distributed and stored. Blockchain is a name given as a block that contains the contents of a transaction, which is a chain.

It is also called'distributed ledger technology' (DLC) or'public ledger' in that it is a technology shared by all network participants rather than being held by a trading entity or a specific institution.

Blockchain, as an example of a technology that can be used to prevent double payments, using cryptocurrency as an example, uses a peer-to-peer (P2P) network. Each block of the blockchain transaction book contains a confirmed transaction history for a certain period of time. Blocks with transaction details are formed online, and blocks containing this information are sent to all participants in the network. Participants can check the validity of the transaction, and only the blocks approved by the participants are connected to the existing blockchain to make transactions.

Transaction books using blockchain principles are distributed and stored on multiple user computers. In the case of Bitcoin, for example, a block is created, which is a bundle of transaction details once every 10 minutes. Blockchain transparently records transaction history in a book that anyone can read, and several computers using the blockchain verify this record once every 10 minutes. According to the theoretical background, blockchain is understood as a technology that is almost impossible to hack, and has the advantage of guaranteeing the transparency of the transaction in that the transaction history is maintained.

On the other hand, apart from the fact that the reliability of each stage of the transaction is maintained in the transaction using the blockchain principle, there is a limitation that the evaluation of the fairness of the information of the transaction itself cannot be made when the initial ledger is created. In particular, when the object to be traded using a public transaction book is a high-value object, it is difficult to verify the value and property of the property when registering the transaction for the first time, for example, for real estate rental. Have In particular, as online transactions are activated, information on false or bait property is provided, which is a problem because many cases of damage have been introduced.

Referring to FIG. 1, the server 100 related to a method for providing real estate security transaction using the blockchain ledger system 500 according to an embodiment of the present invention includes a transmitting/receiving unit 110, an agent management unit 120, and a contract sale management unit 130 ), the contract property registration unit 140, and the cost management unit 150.

The transmission/reception unit 110 may be provided to perform wired and wireless data communication with user devices such as a user device 200 for registration, and an agent user device 300. The transmitting/receiving unit 110 may perform direct communication with the property registration user device 200 and the agent user device 300, or may transmit and receive information through a communication network provided by a third communication provider.

Next, the agent management unit 120 is provided to manage information about the agent. Specifically, the agent management unit 120 may be provided to store, process, and process real estate agent information. The agent management unit 120 is provided to transmit information about the contract request item to at least one agent user device 300 that satisfies a predetermined condition related to the contract request item through the transmission/reception unit 110. In addition, the agent management unit 120 may transmit the brokerage request information to the at least one agent user device (300).

Next, the contract sale management unit 130 is provided to manage evaluation information on the contract request sale or rating information on the contract request sale using the same. When the contract sale management unit 130 receives at least one or more evaluation information on the contract request item from the agent user device 300 through the transmission/reception unit 110, the contract information management unit 130 aggregates the evaluation information received from the agent user device 300 to determine the Rating information for the contract request item may be generated according to the criteria of.

Next, the contract listing unit 140 is provided to manage information on the contract request items suitable for transmission to the blockchain ledger system 500 after the evaluation is completed by the agent. The contract listing unit 140 may transmit information on a contract request item having rating information satisfying a predetermined criterion to the blockchain ledger system 500 through the transceiver 110.

Next, the cost management unit 150 is provided to manage costs required for registration and evaluation of the property. The cost management unit 150 may request the property registration cost to the property registration user device 200 or may pay a predetermined evaluation cost to the agent user device 300, respectively.

2 is a flowchart illustrating a method for providing real estate security transactions using the blockchain ledger system 500 according to an embodiment of the present invention, and FIG. 3 is a block diagram using the blockchain ledger system 500 according to an embodiment of the present invention. It shows a system diagram that can be used in a method for providing real estate security transactions.

Based on FIGS. 2 and 3, a detailed description will be given of a method for providing real estate security transactions using the blockchain ledger system 500.

First, a first step of receiving and receiving a request for registration of a contract request item from the user device 200 for sale is included in the transmitting and receiving unit 110 of the server 100 (S110). The contract request may be real estate for rent or real estate for sale. For example, in the method for providing real estate secure transactions using the blockchain ledger system 500 according to an embodiment of the present invention, direct transactions for real estate sales between individuals and individuals may be made. Transactions for sale are uploaded to the server 100 directly without going through an authorized broker, so that they can be traded. This is because the transaction information is retained through the P2P network according to the distributed transaction method of the blockchain ledger. Because it can.

On the other hand, the first step, the cost management unit 150 of the server 100 may further include the step of requesting the registration fee for the registration to the user registration device 200 through the transceiver 110. . The cost of registering a property can be understood as a cost for evaluating and maintaining registration to register a transaction request item as a property. The blockchain ledger functions as a guarantee for the transaction, but since the verification of the registered property must be performed separately, it is evaluated whether it is an object that can be used for the actual transaction. , Authorized brokers, etc. may be suitable for conducting verification of the transaction request. Brokers such as authorized brokers participating in the evaluation may be paid for the property evaluation, which may be paid using the property registration cost.

At this time, the property registration fee can be paid in points, coupons, cryptocurrency, cash, and the like. At this time, the point, coupon, token (token), cryptocurrency, etc. may be generated by the cost management unit 150 of the server 100, but is not limited thereto, and a separate reward bank system 400 It may be generated from and provided for use.

Next, the agent management unit 120 of the server 100 transmits to the contract request item through at least one agent user device 300 that satisfies a predetermined condition related to the contract request item through the transmission/reception unit 110. A second step of transmitting information is included (S120).

In the case of real estate, for example, the agent management unit 120 may provide real estate rental property or real estate sale property to the agent user device 300, such as an email, mobile phone, telephone, or fax, included in information about the agent performing the real estate brokerage. Information related to the contract request item related to is sent. At this time, the agent receives information about the contract request item only to the agent who satisfies the predetermined conditions.

At this time, the predetermined condition may be whether or not the location of the agency office included in the agent information of the agent management unit 120 is compared with the location information of the contract request item. In the case of real estate, the agent can be an authorized broker. There may be no geographic restrictions on the sale of real estate for which an authorized broker can represent the transaction procedure. Therefore, when a faster and more accurate evaluation of the contract request items, such as real estate short-term rentals, is required, it is desirable to be limited to geographically adjacent authorized brokers so that the contract request items can be evaluated. At this time, geographic proximity can be arbitrarily designated considering the number of agents to participate in the evaluation.

In this case, the agent management unit 120 may transmit a push alarm signal to allow the agent to confirm the contract request sale more quickly through the transmission/reception unit 110.

On the other hand, the second step, the agent management unit 120 may further include the step of transmitting the intermediary request information to the at least one agent user device 300 through the transceiver 110.

For example, when the landlord sends a transaction request to the server 100 for sale, a push alarm is sent to the broker. At this time, the broker requests (at multiple times) the at least one broker who has been contacted within a certain period of time (optionally designated). Possible) It may be provided to selectively transmit the request information. In the case of real estate sales, there are many cases that cannot be handled solely by an intermediary, and it may be necessary to be provided with a bank loan or a lawyer's registration service. In addition, the more the real estate is sold, the faster the contract can be made. Therefore, relay request information is sent to an intermediary in the neighboring region participating in the evaluation to increase the convenience of the transaction.

Next, when receiving at least one or more evaluation information for the contract request item from the agent user device 300 through the transmitting and receiving unit 110 of the server 100, the contract property management unit 130 of the server 100 A) includes a third step of synthesizing the evaluation information and generating rating information for the contract request item according to a predetermined criterion (S130).

The agent may be requested to perform an evaluation of the contract request for sale, and the evaluation result for this may be transmitted to the contract sale management unit 130 to perform a rating evaluation for the reliability of the sale.

In relation to the evaluation, for example, information on real estate contracts, such as transaction conditions (trade conditions such as sales, monthly rent, and charter), area, price, availability of loans, direction, corresponding floor/total floor, waterproof/bathroom, It may be information that introduces the number of households, the year of the tenancy, the charter rate, the parking space, the entrance structure, the number of parking per household, the date of construction, the number of households, the number of construction companies, the number of possible occupants, the heating method, the availability of repairs, or other real estate contracts.

However, the evaluation information is not limited to this, and may include elements recognized as suitable for use in evaluating real estate properties. In addition, the evaluation items that can be included in the evaluation request information are processed and provided in a preset manner (check box method or o,x check method for each item) or a real estate contract received from the user device 200 for sale. Information on the property can be used as it is.

At this time, the evaluation information may be limited to those received within a preset time through the transceiver 110. The time limit may be arbitrarily reduced or increased considering the number of agents participating in the evaluation of the product.

On the other hand, the third step, the cost management unit 150 of the server 100 may further include the step of paying a predetermined evaluation cost to each of the agent user device 300 through the transceiver 110. have.

The sum of the predetermined evaluation costs paid in exchange for the property evaluation may fall within the scope of the property registration cost. Since there is a time limit and a resource limit that provide evaluation information on a property, it is possible to induce the agent's participation by giving a relatively high point to a broker who provides evaluation information more quickly and accurately. In addition, as described above, the agent who participated in the evaluation can perform the brokerage service for the actual contract request for sale in some cases, thereby providing benefits to both the user and the broker who want to register the sale.

As described above, the evaluation cost or the property registration cost may be paid in the form of points, tokens, cryptocurrency or cash with exchange value.

Next, the contract property registration unit 140 of the server 100 transmits information about the contract request item having rating information satisfying a predetermined standard to the blockchain ledger system 500 through the transmission/reception unit 110. Including a fourth step (S140).

The information about the contract request item is transmitted to the blockchain ledger system 500, whereby a substantial transaction can be made. Since only the items that satisfy a certain level are registered and used in the blockchain ledger system 500, concerns about false or bait for tenants or buyers participating in the transaction may be reduced.

In addition, all information about the contract request sale can be transmitted to the blockchain ledger system 500 and used. Therefore, since data for subsequent transactions is prepared and stored in the blockchain ledger, it is possible to reduce the cost of maintaining and maintaining a large-scale storage space for storing information about the transaction request. In addition, since it is impossible to arbitrarily modify and remove the transaction request, the reliability of the contract request can be maintained.

On the other hand, the method, the server 100 further comprises the step of receiving the transaction completion information for the contract request sale from the blockchain ledger system 500 through the transceiver 110, the transaction is completed, The information includes agent evaluation information received from the contract user device, and the agent management unit 120 may be provided to update the agent evaluation information to the agent information.

For example, since most of the bait or false property is provided by the agent, the agent evaluation information is received from the contractor (tenant or buyer) after the transaction is completed, and the agent management unit 120 updates the agent evaluation information. Proactive agents can be blocked in advance.

The agent in question may be sent directly to the lessee or buyer, but is not limited thereto, and the false agent may be eradicated by preventing an evaluation request from being sent to the agent in question. In addition, since the blockchain system ledger provides with high confidence whether the transaction has been completed, information on whether or not the transaction has been completed is provided to the lessee or the buyer, so that it can be checked in advance if the transaction has already been completed.

According to another embodiment of the present invention, the first step of receiving/receiving a request for registration of a contract request item from the user device 200 for sale/receiving unit 110 of the server 100, the agent management unit of the server 100 ( 120) the second step of transmitting information about the contract request item to the at least one agent user device 300 that satisfies a predetermined condition related to the contract request item through the transceiver 110, the server ( When receiving at least one or more evaluation information for the contract request item from the agent user device 300 through the transmission/reception unit 110 of 100), the contract sale management unit 130 of the server 100 receives the evaluation information. The third step of collectively generating rating information for the contract request item according to a predetermined criterion and the rating information that the contract sale registration unit 140 of the server 100 satisfies the predetermined criterion through the transceiver 110 A program for performing a fourth step of transmitting information on a contract request item having a block chain to the ledger system 500 or a storage medium in which the program is stored may be provided.

In the present specification and drawings, preferred embodiments of the present invention have been disclosed, and although specific terms are used, they are merely used in a general sense to easily explain the technical contents of the present invention and to understand the present invention. It is not intended to limit the scope. It is apparent to those skilled in the art to which the present invention pertains that other modifications based on the technical spirit of the present invention can be implemented in addition to the embodiments disclosed herein.
