BitCoin/비트코인 채굴하기

BitCoin/비트코인 채굴하기

1. mining pool 가입하기

- 일반적인 PC로는 1bit coin를 채굴하기 위해서는 수백년이 소요된다.

- 대표적인 사이트 https://bitminter 가입하기

2. 채굴 도구 설치하기

- Java를 통해서 실행되는 Client로서, Java설치가 필요하다.

3. 채굴 Client 실행

- ENGINE START를 누르면, 시작된다.

- Client실행후에 Settings->Account의 설정은 https://bitminter.com/members/workers의 Workers설정과 가입 ID를 사용하면 된다.

- https://bitminter.com/members/workers의 메뉴에서 "Accepted"가 Client에서 작업한 결과를 반영하는 항목이다.

- 이 방식은 GPU를 사용하는 과정으로, ASIC를 사용하는 방식은 설명을 찾아 보면 될 것 같다.
