Abstract

After Bitcoin was proposed by Satoshi Nakamoto in 2009, studies have been carried out to apply the Block Chain technology in various environment, which was applied as a distributed transaction of Bitcoin. Smart contracts, voting and proof of ownership of digital contents are typical applications of Block Chain. They used the feature that it is impossible to modify or delete once recorded facts. They also applied to prove relevant facts and to provide data integrity. The applied cases are mainly made in an environment where the data should or could be open to the public, and they have been proposed as solutions to solve the problems occurred in relations. This fact has led to the attention that Block Chain can be applied as a good alternative in similar circumstances. In this study, real estate market service was selected to expand the application range of Block Chain. Although there are about 250 applications and web services in total, the satisfaction is not high due to false offerings. Thus we propose a countermeasure against the problem by applying the Block Chain to the real estate market service, and investigate the research direction of the Block Chain in the future market.

2009년 사토시 나카모토라는 필명에 의해 비트코인이 제안된 후, 비트코인의 분산형 거래 장부로 응용되었던 블록체인기술을 다양한 환경에 적용하고자 하는 연구들이 진행되어왔다. 스마트 계약, 투표 및 디지털 콘텐츠에 대한 소유권 증명 등이 대표적인 적용 사례로, 한 번 기록된 사실에 대해서는 수정이나 삭제가 불가능하다는 블록체인 기술의 특징을 이용하였다. 또한 관련 사실을 증명하고 데이터의 무결성을 제공하기 위해 블록체인 기술을 적용하였다. 적용된 사례는 주로 공개되어야 하거나 공개되어도 무방한 데이터를 다루는 환경 속에서 이루어졌고, 둘 이상의 관계 속에서 발생된 문제점을 해결하기 위한 방안으로 제안되었다는 공통점을 가지고 있다. 이러한 사실을 통해 블록체인 기술은 유사한 환경에서 좋은 대안으로 응용될 수 있다고 주목받아 왔다. 본 연구에서는 이러한 블록체인 기술의 응용 범위를 확장하고자 실생활에서 겪고 있는 문제 상황인 부동산 시장 서비스를 선정하였다. 부동산 시장 서비스의 경우 현재 앱과 웹 서비스를 통틀어 250여 개가 운영되고 있으나, 허위 매물로 인해 만족도는 높지 않은 문제점이 있다. 따라서 본 연구에서는 앞서 적용된 사례와 유사한 패턴이 발견 되는 부동산 시장 서비스에 블록체인 기술을 적용하여 문제 상황에 대한 대응 방안을 제시하고, 향후 시장에서 블록체인의 연구 방향을 고찰하고자 한다.
