Un procédé de transaction entre une première cryptomonnaie échangée sur la base d'une première chaîne de blocs et d'une seconde cryptomonnaie échangée sur la base d'une seconde chaîne de blocs peut comprendre les étapes consistant à : obtenir des premières informations de transaction relatives à une première transaction dans laquelle un premier utilisateur transmet la première cryptomonnaie à un second utilisateur et des secondes informations de transaction relatives à une seconde transaction qui accompagnent la première transaction et dans laquelle le premier utilisateur reçoit la seconde cryptomonnaie provenant du second utilisateur; si les premières informations de transaction satisfont les termes d'accord entre le premier utilisateur et le second utilisateur, ajouter, aux premières informations de transaction, des premières informations de termes pour activer, sous réserve de la validité des secondes informations de transaction, la première transaction de la première cryptomonnaie; et fixer une signature numérique vérifiant les termes d'accord avec les premières informations de transaction auxquelles les premières informations de termes sont ajoutées, et transmettre celles-ci à un noeud sur le réseau de la première chaîne de blocs. 제1 블록체인에 기반하여 거래되는 제1 암호화폐와 제2 블록체인에 기반하여 거래되는 제2 암호화폐 간의 거래 방법에 있어서, 제1 사용자가 제2 사용자에게 상기 제1 암호화폐를 전송하는 제1 거래에 대한 제1 거래 정보, 및 상기 제1 거래에 수반되는, 상기 제1 사용자가 상기 제2 사용자로부터 상기 제2 암호화폐를 수신하는 제2 거래에 대한 제2 거래 정보를 획득하는 단계; 상기 제1 거래 정보가 상기 제1 사용자와 상기 제2 사용자 간의 합의 조건을 만족하면, 상기 제2 거래 정보의 유효성에 종속되어 상기 제1 암호화폐의 상기 제1 거래를 활성화 시키는 제1 조건 정보를 상기 제1 거래 정보에 추가하는 단계; 및 상기 제1 조건 정보가 추가된 제1 거래 정보에 상기 합의 조건을 증명하는 디지털 서명하여, 상기 제1 블록체인의 네트워크 상의 노드로 전송하는 단계를 포함할 수 있다.
