Abstract

Recently, research on CBDC (Central Bank Digital Currency) has been actively conducted for various reasons by countries around the world. In addition, with the dazzling development of blockchain technology, blockchain technology is being adopted in CBDC. In this paper, we propose a blockchain-based CBDC system that can be effectively used in the traditional banking system. We also analyze the requirements of CBDC and suggest ways to commercialize CBDC. We present a system design and implementation method, especially in terms of compatibility, interoperability, and privacy.

최근 들어 국가별 다양한 이유로 CBDC (Central Bank Digital Currency)에 대한 연구가 활발하게 진행되고 있다. 아울러 블록체인 기술의 눈부신 발전에 따라 이를 기반으로 한 CBDC 시스템이 주목을 받고 있다. 이러한 배경하에 본 논문에서는 기존 은행권에서 효과적으로 사용할 수 있는 블록체인 기반의 CBDC 시스템을 제안하였다. CBDC의 개발과 상용화를 위한 은행권의 여러 요구사항을 분석하였으며, 이를 바탕으로 호환성, 상호운용성, 프라이버시 측면에서 효과적인 시스템 디자인과 이의 구현 방법을 제시하였다.
