Accordingly, a secure chatting service between members is supported to be available. 블록체인 네트워크를 형성하고 있는 복수의 노드 장치들과 연동하여 보안 채팅 서비스를 제공하는 채팅 서비스 서버 및 그 동작 방법이 개시된다. 본 발명은 복수의 회원들 각각의 개인키에 대응되는 공개키를 기초로 채팅방에 참여하는 각 회원에 대한 증명 데이터를 발급해 주고, 각 회원의 증명 데이터와 공개키를 블록체인 네트워크에 등록해 둔 후, 채팅방에 참여한 특정 회원의 단말로부터 소정의 콘텐츠를 채팅방에 게시할 것을 지시하는 콘텐츠 게시 요청이나 채팅방에 게시되어 있는 콘텐츠에 대한 다운로드 요청이 수신되면, 상기 블록체인 네트워크에 등록된 증명 데이터와 공개키를 기초로 콘텐츠 게시 요청이나 다운로드 요청을 전송한 회원에 대한 인증을 완료한 후, 회원 인증이 완료되면, 상기 콘텐츠에 대한 게시를 허가하거나 상기 콘텐츠의 다운로드를 허가함으로써, 회원들 간의 보안 채팅 서비스가 가능하도록 지원하는 채팅 서비스 서버 및 그 동작 방법에 대한 것이다.
