Abstract

La présente invention relève du domaine de la chaîne de blocs. Elle concerne plus précisément un procédé et un dispositif de communication entre des nœuds de chaîne de blocs, un support de stockage et un appareil électronique. Le procédé comprend les étapes consistant à : lorsqu'un premier nœud de chaîne de blocs reçoit une demande de communication envoyée par un second nœud de chaîne de blocs, déterminer si la demande de communication est la première demande de communication reçue ; s'il s'agit de la première demande de communication reçue, déterminer s'il existe une relation commerciale entre les second et premier nœuds de chaîne de blocs ; le cas échéant, configurer les premier et second nœuds de chaîne de blocs dans le même réseau local ; et établir une connexion de communication entre les premier et second nœuds de chaîne de blocs dans le réseau local. Dans la présente invention, les premier et second nœuds de chaîne de blocs présentant une relation commerciale sont configurés dans le même réseau local. De plus, la connexion de communication entre les nœuds est établie dans le réseau local de telle sorte que les deux nœuds n'ont pas à communiquer par l'intermédiaire de passerelles à multiples niveaux, ce qui accroît la vitesse de transmission des données et améliore l'expérience utilisateur.
