Abstract

La description se rapporte à un procédé et un appareil de traitement de données fondé sur une chaîne de blocs, et à un dispositif électronique. Selon un exemple, le procédé est appliqué à une plateforme de gestion, la plateforme de gestion étant utilisée pour gérer un réseau de service à chaînes de blocs composé d'une pluralité de chaînes de blocs ; et le réseau de service à chaînes de blocs fournit un service de registre à chaîne de blocs pour un utilisateur. Le procédé consiste : à recevoir des données de service et des informations d'utilisateur d'un utilisateur, envoyées par un terminal utilisateur ; en fonction des informations d'utilisateur, à déterminer, dans un réseau de service à chaînes de blocs, une chaîne de blocs cible qui fournit un service de chaîne de blocs pour l'utilisateur ; et à envoyer les données de service à un dispositif de nœud de la chaîne de blocs cible, de façon à mémoriser dans un registre les données de service sur la chaîne de blocs cible.
