Welcome to Coinext (Silverstring-Exchange)

오픈소스 가상화폐 거래소 Coinext (부제 : Silverstring-Exchange)

  • 만든이 : [email protected] (닉네임 : 나사못도 살포시)

  • 언어 : Java 1.8

  • 스킬 : spring boot, redis, rabbitmq, mysql, jpa, websocket, jquery, bootstrap, ipfs, clientjs

  • 사용 솔류션 : rabbitmq, redis, mysql, google mail

  • 목적 : 가상화폐 거래소를 만들고 싶어하고, 어떻게 구동되는지 알고싶은 많은 개발자들에게 기술을 오픈하고 싶어서..

  • 거래소 데모 페이지 : https://www.coinext.net (가입을 하고 둘러볼수있습니다)

  • 거래소 관리 페이지 : http://218.38.19.7:8181 (어드민 권한 사용자만 로그인 사용가능합니다)

  • 개발 중점 : 기준 거래소들의 성능저하의 원인을 극복하고, 클라우드 환경에서의 scale out하게 서버를 확장가능하도록 구현하고, 비동기 방식과 메세지큐를 사용하여 퍼포먼스를 향상함.

  • 최적화 : 리팩토링 작업 남음.

  • 구동 방법 : rabbitmq, redis, mysql 설치하시고,application.properties쪽에 설정정보 채워서 구동하면됩니다. 아래쪽에 DB스키마를 참고해주세요.

저는 5년전부터 비트코인, 가상화폐, 블럭체인쪽에 많은 관심을 가져온 개발자입니다.

비트코인 20만원할때, 이더리움 1천원 할때, 몇만원씩 구매해서 신기해서 전송도 해보고, 에스크로 거래도 만들어보고, 지갑도 설치해서 jsonrpc로 통신도 해보고,솔라디티 dapp도 만들어서 구동해보고 하면서 독학으로 지식을 쌓아왔습니다.


지금 시세로 보니 몇천만원은 되더라구요 ㅠ


암튼, 관심을 갖고 이분야로 많은 글을 접하고, 기술을 알아가니 자연스럽게 거래소의 흐름이 머리속에 그려지는 단계가 되어버렸습니다.


원래는 책을 쓰려고 했지만,, 역시나 귀차니즘이 또 엄습을..


1달여 기간동안 매일 2-3시간정도를 들여서 틈틈히 만들어봤습니다.. 거래소의 단점인 퍼포먼스쪽, 특히 입금시 콜드월렛으로 바로 전송하는 부분은 min수량을 설정해서 적은수량일경우는 콜드월렛으로 전송되지 않게 함으로써, 복잡도를 낮췄고, 입금,출금쪽은 거래내역을 이원화하여, 메세지큐 방식을 사용하였습니다.


각각 다른 지갑의 jsonrpc 프로토콜은 공통된 인터페이스를 사용하여, 추상화하여 사용하였습니다.


너무 단기간에 만들어버려서, 수정하고 고쳐야할 버그들이 산재하겠지만, 개발자분들에게 거래소의 기본 플로우와 메카니즘을 익히는데는 부족함이 없을듯합니다.


FT쪽은 제가 실력이 많이 모자라서, 꾸역꾸역 jqury로 만들어냈습니다. 실력있는 FT개발자분들이 많이 고쳐주실꺼라고 생각합니다~


한국 개발자분들에게 조금이나마 도움이 됬으면 하는 바램이며,


앞으로 IPFS, BLOCKCHAIN, DAPP관련하여 몇가지 오픈소스화 를 목표로 만들고있는 프로젝트들이 있는데,


이 프로젝트도 조만간, 오픈소스로 공개하도록 하겠습니다 !!
