Vanio vs HomeChat

Vanio는 전화번호나 이메일 대신 지갑 주소를 기반으로 대화를 시작하는 보안 메신저입니다. QR 코드, 직접 주소 입력, 초대 링크로 친구를 추가하고 메시지와 사진을 주고받을 수 있습니다. 주요 기능 - 지갑 주소 기반 계정 생성 - QR 코드 스캔, 내 QR 표시, 직접 주소 입력, 초대 링크 공유 - 종단간 암호화된 1:1 메시지 - 암호화된 사진 전송 및 보기 제한 옵션 - 안전번호와 QR 비교를 통한 상대 신원 확인 - 연락처 별칭 저장 및 암호화 백업 - 차단, 신고, 서비스 탈퇴 기능 - 새 메시지 알림 보안 및 개인정보 메시지와 사진 내용은 전송 전 기기에서 암호화됩니다. 서버는 메시지 전달과 동기화를 위해 필요한 암호문, 주소, 기기 정보 등 일부 데이터를 처리하지만, 메시지와 사진의 평문 내용은 볼 수 없습니다. Vanio는 아직 초기 버전이며, 현재 제공되는 기능 기준으로 계속 개선 중입니다.
