Abstract

세계적 열풍의 중심인 비트코인에는 많은 이슈가 발생하고 있다. 특히 비트코인의 익명성은 사회적으로 중요한 문제이다. 비트코인이 익명성을 보장하지 못할 경우 거래내역이 공개되어 프라이버시가 노출될 수 있다. 반대로 비트코인이 익명성을 보장할 경우 마약 거래, 자금 세탁, 랜섬웨어 공격 등의 각종 범죄가 발생할 수 있다. 이밖에도 다양한 상황에 적절한 대처를 하기 위해서는 비트코인 기술에 대한 정리와 이해가 필요하다. 본 논문에서는 비트코인의 익명성을 약화시키는 클러스터링 기술과, 비트코인의 익명성을 강화시키는 믹싱 프로토콜 기술에 대한 연구 흐름을 정리하였다.
