How Smart Contrator work
Currently, more than 500 real estate-related services are available across the app and the Web. These online services not only involve more than half a million properties operating offline but also involve individual users to provide an environment for easy sharing of goods.
Although they were popular for being easy to identify and promote, all of them were not very satisfied with the false sale.
Each service mainly adopts a method that is reported by users as a countermeasure against false sales. But report Many say that the follow-up process is insufficient in cases of doing and that the method of verifying the sale through a professional agent is less effective than the additional cost.
In addition, it is possible to sort out registered false sales, but it is not possible to block registration of false sales. After all, it is not a fundamental solution.
The process of identifying and verifying systematically is insufficient. With the advent of various online services, real-estate agents have increased the process of registering and verifying advertisements for the products they manage. In addition, the process of checking the contract of a registered product is manual, so if there are any missing items in the process, the sale will be a false sale.
In order to solve the problem of false sales, it must first be resolved by registering with separate data depending on the registrant even if the same sale is previously available. Using blockchain, the registers entered information by connecting to the same media.
Thus, the problem of registering as separate data can be solved. This is the biggest difference between the database structure used by existing services. The advantage of this method is that if different users register information for the same medium, the blockchain technology can identify which information is false based on the database. It is said that a mutual monitoring system can be established between users who manage information by connecting with each other.
For example, there are 4 real agency a, b, c, d and property x. The real-agency a, b, c registered the correct information for property x, but d was arbitrarily changed to the price or size of x. This will create the same data tree between the same information for the property x listed in the blockchain, but a branch will occur for the other information. If this fact is to be presented, real agency d would be suspected of false listing information.
In addition, if additional method is prepared to be registered through the signature of the owner of the sale before registration, fake information cannot be registered in advance.
Similarly, if the contract was completed through real agency a, the additional information because of the nature of the block chain would be disseminated to all participating parties, so that the transaction was completed without a direct check in Real Estate b, c, and d.
As the characteristics of the blockchain, changed information will spread to all participating agency, so other agencies do not need to check directly. They can see all changed information though the blockchain. This also prevents false sales caused by omission.
Block Chain Application
By introducing blockchain in the real estate market, the target is a buyer, a seller, a real-estate developer and an advertiser as a way to solve the problem by forming a cross-monitoring system between real-estate. Application and Web Services which are provided through purchasers, sellers, and real-estate agents can all be accessed through applications and Web services and are different work screens. To summarize the flow of the sale data, the seller requests the sale to the real-estate agent or registers it directly in the service. A confirmation message is then sent to the intended person who wishes to sell the service in order to register the information registered in the block chain. Purchase only the property information that was signed with confirmation of the seller's wish to be sold in the block chain.
It may be released on the desired page. Here's a closer look at these services:
As a result of looking at the composition of online services, four types of cases involving the real estate market were classified. Buyers who want to buy or rent a sale, want to trade in owned or occupied goods to others, real estate agents who link the purchase wisher to the sale and manage the sale between transactions, and advertisers who can promote the sale, such as traditional online services.
The purchaser is the person who wants to own or move the goods. The entity can access the information about the sale through the application or web service provided and can also check the information about the sale through a page provided by the advertiser.
Convenience is also a priority for the model you propose to consider, as it is the target that has been victimized the most by false sales in the service.
Under the proposed method, the purchaser may check the purchase data to the desired conditions and register the items with the object of interest. Therefore, the roles required for prospective buyers are minimized, making it easier to provide.
The advantages of using a spoon are the same. In addition, the reliability index can be found on the screen that the prospective buyer sees. First of all, the list of products will appear in order of high confidence index of search results. In addition, the reliability index of the information of the sale is displayed together with the number of properties registered for the same sale and the depth at which the block chain has progressed.
Therefore, if a non-existing sale has been registered or is different from the information registered in another property, the warning for the suspected false sale can be identified for that information and property.
In addition, the list of real estate recommendations can be checked in order of confidence indicators when dealing with a good medium to ensure reliability in the transaction process. In this service environment, prospective buyers can verify reliable sales information by simply touching or clicking on the screen and make transactions through reliable real-estate.
Desired to sell
A seller is a person who wants to sell his or her own goods, rents, or trade with another buyer. The purpose of this section is to provide data on the registration of goods to targets that can be directly registered or requested to a real-estate agent, and to proceed with the process of registering them in the blockchain.
All the products to be registered are subject to the approval phase of the seller's certification. When registering the products in person, it is easy to authenticate yourself. If requested to a real-estate agent, the property is not changed.
The project sites are organized so that they can be monitored first and registered with accurate information. In other words, if requested to a real-estate agent, the real-estate agent registers the sale information via application or web service, and a confirmation message is sent to the seller.
The seller will check the information registered by the real-estate agent and sign it if it is correct and the signed item information will eventually be listed in the blockchain to form a tree. The information registered through this process will be disclosed through the Purchaser's page.
Real Estate Entity
Real-estate agents are in the most profitable relationship in real-estate transactions. The target is to obtain information about the sale and to register it and manage it and to connect it to the purchaser. It is the most important role in the operation of the real-estate market and also the role that creates a problem factor.
To prepare for a malicious vendor, the first case of a false sale, the real-estate agent was required to be certified by the seller whenever he wanted to register the sale data.
And even though the block chain was passed through the blockchain through false sales, due to the branching characteristics of the blockchain, which is the basis for the confidence index evaluation, the real-estate agent was put in place.
It is a structure that must be reasonably suspected by every hopeful. The second case in which false sales occur is constructed so that it can be easily resolved using the characteristics of the blockchain.
Changes in the sales you manage are automatically propagated and shared by all participants, eliminating the hassle of identifying them individually.
The more information you register, the more confident you are, the more confident you are, and this leads to an opportunity to broker a contract.
The advertisers are now subject to the provision of space to promote their products, such as real-estate online services.
The first item to be registered in the blockchain will be registered in ads through an automatic script. After that, there is only an additional link for the sales registered by the real-estate agent.
Also, if the sale is completed, the advertisement uploaded through the automatic script of the blockchain is configured to be changed, so there is room for the problem of the advertiser due to the false sale.
The biggest feature of the block chain is that it is not possible to change the listed content once, forms a tree in the process of accumulating the data, and branches off the heterogeneous data. The proposed model aims to take advantage of this to improve reliability in the real estate market
<Figure 1> Tree Branch Process of Block Chain.
As in <Figure 1>, the block chain connects between data blocks and forms a tree. Ensures the reliability of previously registered data if the same data is received for the same keyword. If other data came in, a branch would occur, which would result in the selection of a direction that would have been made before and more stacked. That is, the more identical data, the more forward the tree is selected. In < Figure 1>, the black blocks follow the selected branching direction.
Other blocks indicate when they are being burned and contain heterogeneous data. Considering this by applying it to the real estate market, information such as the standard or amount of the sale is used for identification purposes using the unique identification data held by the sale. Even if a malicious real estate agent passes the certification process and registers his information in the block chain, the probability of gaining credibility is low due to the nature of the tree branches of the block chain.
There are two main reasons for that. The first reason is usually due to the social structure in which the sale is entrusted. This is because, in general, many properties are entrusted with their own sale, false information should be the same as all other properties to obtain reliability.
The probability of sharing information registered for their own advantage with other vendors is lower than the probability of other vendors registering the correct information, which makes it difficult to gain credibility.
The second reason is that once a sale has been closed and transferred to another purchaser and the person has re-sale, it is difficult to register it with the same information as the information previously listed as false.
This is because previous data and quarters occur, and the real estate agent on the side with the longer node increases confidence, while the real estate agent in the case of the node not increasing is an architecture that creates a reasonable doubt about the previous record and reduces confidence.
Because block chain cannot modify the recorded data once, it must continue to notify the purchaser of the property that has previously posted the false sale in advance and receive a disadvantage.
The key to the model that we're proposing is to use block chain to create a mutual monitoring system between real estate agents to ensure that only highly reliable information exists within the service.
It's the principle of interest.
Operating Strategies of Block Chain Application Services
The situation in which the proposed model operates can be divided into two main categories. The first is to sell the goods, and the second is to buy the goods. We described the benefits of using block chain through a process that works according to each situation.
Purchasing users can check registered media data through advertising sites or by using their own services. You can perform a search based on the desired conditions, and you can view the media in the order in which it is highly reliable under those conditions.
You can also choose to register the sale of interest and verify that the registered sale of interest has been contracted before the contract with the purchaser. In addition, the details of the sale include information on the recommended property in the order of reliability.
These features enable you to deliver on-the-go data from information to contracts ensure integrity and reliability.
If the transaction is completed, the credibility of the real estate transactions will increase, and the records of the transactions will be registered in the blockchain books after certification by the buyers and the sellers. The listed content will be disseminated to all participants, so not only the real estate where the goods were managed.
The products will be automatically forwarded to buyers who have set interest in them. In addition, the automatic execution script for registration reduces the inconvenience of checking a sale's contract and prevents false sales that occurred during the verification process.
The sales applicant registers the goods he/she intends to trade with the service, or he/she registers the sales information at the request of the real estate agent. Registered information can prevent registration of false sales and check data once more. Data that has been certified will be recorded in the block chain. The first registered information will be automatically registered on the ad site and, in the case of records previously registered, the relevant information such as price and size will be determined to form a tree.
The response to registered media data can be easily identified through the service. Since data is continuously stacked according to the tree-making rules of the block chain, low-reliability information in the service market will not exist on the service screen, as the depth of the data or false information are not reached and the leaf for that case will be eliminated.
