초록

국민주택채권 정보 중계시스템은 관련된 여러 기관들이 중계센터를 중심으로 연결된 대표적인 금융정보 중계시스템이다. 이러한 중앙 집중형 구조는 중계센터 구축 및 운영에 막대한 비용이 소요되고, 센터시스템에 장애나 사고가 발생할 경우 모든 네트워크가 단절되는 문제점이 존재한다. 본 논문에서는 블록체인 기술을 활용하여 안전하고 효율적으로 정보를 처리할 수 있는 블록체인 기반의 국민주택채권 정보 중계시스템 모델을 제안한다. 제안 모델은 국민주택채권 정보를 처리하는 각 기관들이 안전하게 정보를 전송할 수 있도록 블록체인 네트워크를 구성하고, 스마트 컨트랙트 기반의 분산 어플리케이션으로 동일한 분산원장을 관리한다. 제안 모델은 중계센터 없이 복잡한 국민주택채권 거래 정보를 처리할 수 있어 비용을 절감할 수 있으며 기존 시스템 대비 네트워크 사용률의 1.7%, 디스크 사용률의 8.53%의 개선 효과가 있다.

The National Housing Bond Information Relay System is a representative financial information relay system in which institutions are connected with center system. A centralized structure is expensive to construct and operate center, and there is a problem that all networks are disconnected when a failure occurs in the center system. In this paper, we propose the national housing bond information relay system model based on Blockchain technology that can process information safely and efficiently. The proposed model constructs a Blockchain network so that each institution that processes the national housing bond information can transmit information safely, and each institution manages the same distributed ledge by a smart contract. The proposed model can reduce the cost because it can process complicated national housing bond transaction information without a relay center, and a network usage and disk usage decreased by 1.7% and 8.53%.
