저희가 설명을 해드리지요. 그럼 그 이유를 살펴 보도록 하겠습니다.</em></p> <h2 class="wp-block-heading">‘개인의 키’란 무엇일까요?</h2> <p>은행 계좌와 비슷하게 암호화폐도 수령 주소로 전송됩니다. 이 주소에 대한 전문 용어가 바로 <em><a href="https://www.ledger.com/ko/academy/개인-키와-공개-키는-무엇인가요" target="_blank" rel="noreferrer noopener">공개 키</a></em>입니다. 누군가가 귀하에게 비트코인을 전송하면 이는 귀하의 공개 키로 전송됩니다. 공개 키라고 불리는 이유는 암호화폐를 훼손하지 않고 누구에게나 보낼 수 있기 때문입니다.</p> <p>그런데 공개 키와 관련한 또 다른 키가 있습니다. 바로 <a href="https://www.ledger.com/ko/academy/개인-키와-공개-키는-무엇인가요" target="_blank" rel="noreferrer noopener"><em>개인 키</em></a>입니다. 이 키는 매우 중요합니다. 개인 키에 접근할 수 있는 사람은 누구나 개인 키와 연결된 공개 키의 자금에 접근할 수 있습니다. 더 단순히 말해 개인 키는 귀하가 진짜 소유자임을 밝혀주는 수단인 비밀번호와 유사합니다. ‘키가 내 것이 아니면 코인도 내 것이 아니다’라는 표현에서 키는 바로 이 개인 키를 의미하는 것입니다.</p> <h2 class="wp-block-heading">코인에 대한 액세스와 그 소유의 차이점</h2> <p>평소에 자주 이용하는 거래소에 로그인해 보면 본인 계정의 코인이 마치 자신의 소유인 것처럼 느껴질 것입니다. 그런데 코인에 액세스를 하기 위해서는 사실상 로그인을 해야 합니다, 그렇죠?</p> <p>틀렸습니다. 겉으로 <strong><em>보기에는</em></strong> 본인이 자신의 자산을 완벽히 제어하고 있는 것 같습니다… 그러나 플랫폼 허용치보다 더 많거나, 특정 한도에 미치지 못하는 액수를 인출하려고 하면 상황이 달라집니다. 사실상 이 거래소는 귀하가 시도하는 모든 암호화폐 트랜잭션을 차단할 수도 있습니다. 거래소가 그렇게 할 수 있는 이유는 귀하 계정의 암호화폐에 대한 개인 키를 바로 이 거래소가 가지고 있기 때문입니다.</p> <p>이러한 현상은 거래소에만 국한되지 않습니다. 이는 자산과 관련한 키의 소유를 허용하지 않는 모든 지갑 공급자에게도 해당됩니다. 개인 키를 소유하지 못하면 귀하는 자금을 진정으로 소유하지 못한 채 이를 제3자에게 위임하는 것입니다.자 이는 사실상 거래소가 귀하 계정의 암호화폐로 본인들이 원하는 무엇이든 할 수 있다는 의미입니다.</p> <h2 class="wp-block-heading">키를 소유하는 것이 왜 중요한가요?</h2> <p>자금을 제3자의 관리하에 두는 것이 아니라 본인이 직접 키를 소유해야 하는 이유는 무수히 많습니다. </p> <p>가장 쉬운 예는 잘못해서 키를 악의적인 세력에게 위임하는 것입니다. 만약 자신의 돈을 악의적인 제3자에게 맡겼다면 그 돈은 다시는 볼 수 없을 것입니다. 다행히도 이러한 일은 유명 회사에 맡긴다면 일어날 가능성이 매우 낮습니다.</p> <p>그렇다고 해도 본인 돈을 전적으로 본인이 제어하는 일은 불가능합니다. 앞서 말씀드렸듯이 이런 회사들의 경우, 최대 인출 한도나 서비스 이용 수수료와 같은 특정한 제한이 있을 수 있습니다. 귀하가 힘들게 번 돈을 가지고 본인이 무엇을 할지를 이러한 회사가 결정하는 것입니다. 또한 만약 이들의 플랫폼에 기술적 문제라도 생기면 사실상 귀하는 본인의 암호화폐에 접근이 차단되게 됩니다. 간단히 말해 키를 본인이 가지고 있지 않은 한 재정적 자유를 얻지 못하고 귀하의 자금은 다른 누군가의 처분을 기다려야 하는 상태로 남습니다. </p> <p>이뿐만 아니라 해당 플랫폼의 시스템 보안에 대해서도 귀하는 제어권이 없습니다. 본인의 암호화폐에 대한 보안 책임도 회사에 위임했기 때문입니다. 불행히도 지난 몇 년간 대형 해킹 사건이 여러 건 일어나, 그 피해액이 <a href="https://www.ledger.com/ko/academy/암호화폐-해킹-타임라인" target="_blank" rel="noreferrer noopener">약 20억 달러</a>에 달합니다.</p> <p>하지만 본인이 자신의 개인 키를 소유하면 상황은 달라질 수 있습니다. 개인 키를 소유함으로써 본인이 스스로 규칙을 정할 수 있습니다. 누구도 귀하의 암호화폐를 놓고 감 놔라 배 놔라 할 수 없습니다. 개인 키를 소유함으로써 자신의 코인을 완벽히 소유하게 되며 재정적 자유도 누릴 수 있게 됩니다.</p> <p>그러나 이 키의 소유는 중요한 책임이 따릅니다. 본인이 개인 키를 보유하는 유일한 사람이 될 수 있도록 스스로 보장할 수 있어야 한다는 것입니다. 만약 누군가 다른 사람이 그 키를 손에 넣으면 그 사람은 귀하의 암호화폐에 액세스하여 화폐를 훔쳐갈 수 있습니다.</p> <p>바로 여기서 Ledger의 역할이 부각됩니다.</p> <h2 class="wp-block-heading">Ledger: 귀하의 키와 코인을 안전하게 관리해 보세요.</h2> <p>Ledger는 하드웨어 지갑을 통해 개인 키, 더 나아가 귀하의 암호화폐에 대한 최고 수준의 보안성을 제공하여 재정적 자유로 가는 길을 안내합니다. </p> <p>당사 제품은 컴퓨터나 스마트폰에 개인 키를 노출시키는 일 없이 이를 안전하게 보관해 줍니다. 이는 누군가 귀하의 PC를 해킹하더라도 귀중한 암호화폐에는 접근할 수 없다는 의미입니다. <a

견뎌낼 수 있습니다.</p> <p>Ledger의 하드웨어 지갑은 사용하기 쉬우며, 접근이 용이하지만 동시에 안전한 솔루션을 제공해 사용자에게 마음의 평화를 선사합니다. 간단히 말해, Ledger의 제품은 키에 대한 소유권을 통해 코인도 안전하게 소유할 수 있도록 해줍니다.</p> <p>하지만 이게 다가 아닙니다. 전문적으로 제작된 소프트웨어를 통해 <a aria-label=" (opens in a new tab)" href="https://www.ledger.com/ko?page_id=80074" target="_blank" rel="noreferrer noopener">Ledger Live</a>는 사용자에게 자산에 대한 완전한 제어권을 돌려줍니다. 뿐만 아니라 다양한 암호화폐를 관리할 수 있는 단일
