Abstract

Les modes de réalisation de la présente divulgation concernent un procédé, un appareil et un dispositif d'invocation de contrat intelligent à base de chaîne de blocs. Le procédé comprend : la réception d'éléments d'informations de transaction envoyés par un client, chaque élément d'informations de transaction incluant des informations de chemin d'un contrat intelligent, à exécuter, correspondant aux informations de transaction ; l'introduction des éléments d'informations de transaction reçus dans un ordonnanceur de sorte que l'ordonnanceur distribue les éléments d'informations de transaction à différents exécuteurs ; l'interrogation d'une unité de stockage au moyen des exécuteurs et sur la base des informations de chemin des contrats intelligents, à exécuter, correspondant aux éléments d'informations de transaction, de façon à acquérir des contrats intelligents correspondant aux éléments d'informations de transaction, l'unité de stockage incluant des contrats intelligents qui sont stockés selon une structure arborescente de répertoires de fichiers, et le chemin de stockage de chaque contrat intelligent est unique ; et l'exécution des contrats intelligents sur les éléments d'informations de transaction au moyen des exécuteurs de façon à obtenir un résultat d'exécution. Il n'est pas nécessaire que des exécuteurs synchronisent des données de table CNS liées à des contrats intelligents puisqu'une exécution simultanée est réalisée sur une transaction, ce qui améliore l'efficacité d'une chaîne de blocs lorsqu'une exécution simultanée de contrats intelligents est réalisée sur des informations de transaction.
