Abstract:

The existing real estate transaction is highly interested in a contract that is guaranteed to be reliable due to anxiety about the threat of fraud. In particular, it is timely and economically efficient to manage contract information online and prevent forgery and duplication of contract information. Blockchain technology is emerging as an alternative to the enormous cost and reliability issues associated with offline real estate contracts. If blockchain technology is applied to online contract management, reliability and scalability are efficient and confidentiality can be ensured. Therefore, in this paper, we designed an Ethereum-based online real estate contract management system among blockchain technologies. The real estate contract management system enables online contract management and discrimination of contract forgery through blockchain. In particular, it was possible to prevent fraud until the contract was concluded and the contract was terminated
