Abstract

Smart contract based on the blockchain technology can be applied to the real estate registry including transactions. The Ethereum coin using multi layered protocol is widely accepted as the token for the smart contract. Block chain smart contract using SOLIDITY or PYTHON can mediate transactions auch as sale or lease, creating various scenarios in the property market. Those smart contract can construct the basis for the blockchain real estate registry, which is expected to overcome conventional transaction costs concerning the national law system, the asymmetric information and the currency exchange. The advantages of blockchain technology, namely security, decentralization, global transparency and openness can be applied to the smart contract system on the property registry. Several countries have advanced such blockchain real estate registry project recently, but no actual implementation has been reported for years, owing to institutional and technological impasses.

블록체인 기술을 부동산등기 및 거래에 적용하는 스마트계약은 다층식 코딩이 가능한 이더리움 기반의 시스템 구축이 보편화되고 있다. SOLIDITY 또는 PYTHON으로 코드화되는 스마트계약의 구축은 매매와 임대를 포괄하는 다양한 종류의 시나리오를 통하여 실현될 수 있는데, 스마트계약이 적용되는 부동산시장은 국경, 언어, 법제도, 비대칭 정보, 환전 등의 전통적 거래비용을 크게 감소시킬 수 있는 대안으로 기대되고 있다. 블록체인 고유의 투명성과 보안성, 분산성과 개방성 역시 그 높은 잠재력을 평가받고 있다. 다만 최근 부동산등기를 블록체인 네트워크에 구현하려는 프로젝트가 여러 나라에서 추진되고 있으나 완비된 새 제도로서 현실에서 운용되기까지는 아직 몇가지 난관이 남아있다.
