      자주 묻는 질문

      블록체인은 무엇인가요?

      여러 정보들이 포함된 블록이 시간 순서대로 연결되어 체인의 구조를 이루는 것으로, P2P구조를이루는사용자들끼리동일한데이터를 유지하게 하는 분산 컴퓨팅 기술 기반의 원장 관리 기술입니다.

      일반인들도 자신의 컴퓨팅자원을이용해비트코인을채굴할수 있나요?

      현재 비트코인 채굴을 위한 난이도가 높아져 채굴하기 위해서는 별도의 장비(ASIC)와 많은양의전력을소모해야합니다.사실상 개인이 비트코인을 채굴하는 것은 매우 어렵기 때문에 마이닝 풀을 이용해채굴에참여할수있습니다.

      아무나 비트코인 네트워크에 참여할수있나요?

      비트코인 네트워크는 누구든 참여할 수 있는 퍼블릭 블록체인으로, 다른 사람의 동의나 승인이 없더라도 인터넷에 연결된 PC,노트북, 서버 등 다양한 컴퓨터 장비를 이용해 참여할 수 있습니다. 비트코인 코어클라이언트프로그램을 설치하여 쉽게 네트워크 의한 노드로써 참여할 수 있습니다.

      PoW는 어떤 단점이 있나요?

      채굴자들은 블록을 생성할 권한을 얻기 위해 더 빨리 수학 문제를 풀려고 경쟁하게 되고, 더 계산력이 좋은장비를 구매하려 합니다. 수학 문제를 풀기 위해 무의미하게 많은 양의 에너지를 소비하게 되고, 컴퓨티 자원을 많이 가지고 있는 채굴자에 의해 네트워크가 제어될 수 있다는 문제점이 있습니다.

      비트코인과 같은 암호화폐는계속해서가치가변하는데어떻게암호화폐를 지불 수단으로 활용할 수 있나요?

      암호화폐의 가치 변동은 판매자 또는 구매자의 잠재적인 손실로 이어질 수 있습니다. 이를 해결하고,암호화폐를 전자지불 수단으로 사용하기 위해 가치가 일정하게 유지되는 스테이블 코인이 등장하게 되었습니다.

      암호화폐를거래하고싶은데,어떻게시작하면되나요?

      암호화폐를 구매 및 판매하기 위한 가장 단순한 방법은 암호화폐 거래소를 이용하는것입니다.암호화폐 거래소를선택하고,개인키, 공개키를 보관하기 위한 암호화폐 지갑을 생성하면 됩니다. 암호화폐 거래소에서 계정을 만들면 거래소가 관리하는 거래소 지갑이 자동으로 생성되지만 키를 더 안전하게 보관하기 위해 개인 지갑을 생성하는 것이 좋습니다.
