초록

블록체인은 암호화폐의 거래가 활발해짐에 따라 다양한 분야에서 접목시키려는 노력이 계속해서 이어지고 있다. 블록체인은 한번 기록된 사실에 대해서는 수정 및 삭제가 불가능하다는 특징이 있다. 이러한 특징으로 인해 특히 투표나 소유권 증명과 같은 어떠한 사실을 기록하고 증명하는 분야에서의 활용이 주목받고 있다. 본 논문에서는 블록체인의 유형 중 하나인 프라이빗 블록체인을 활용하여 거래 과정에 참여하고자 하는 이용자들을 부동산 중개인, 건물 소유주, 매입인(임대인)으로 구분하여 이용자별 역할을 부여한다. 또한, 기관이 참여하여 신뢰성을 높이는 시스템을 제안하고자 한다. 이를 통해 허위 매물, 사기 계약 등과 관련된 부동산 사기 피해를 방지하고 신뢰성 높이는 부동산 거래 시스템을 제시할 뿐만 아니라 향후 블록체인 활용 방안 모색에 있어 기여하고자 한다.

Efforts to incorporate blockchain into various fields are continuing as cryptocurrency transactions become more active. Blockchain has the characteristic that once recorded facts cannot be modified or deleted. Due to these characteristics, the use in the field of recording and proving certain facts, such as voting or proof of ownership, is attracting attention. In this paper, users who want to participate in the transaction process using private blockchain, one of the types of blockchain, are divided into real estate brokers, building owners, and purchasers (lessors), and roles are assigned to each user. In addition, we would like to propose a system to increase reliability through the participation of institutions. Through this, we intend to not only present a real estate transaction system that prevents damage from real estate fraud related to false sales and fraudulent contracts, but also enhances reliability and contributes to finding ways to utilize blockchain in the future.
