Abstract

Procédé et appareil de vérification de transaction de demande de ressources basée sur un réseau de chaînes de blocs, dispositif électronique et support d'enregistrement lisible par ordinateur, appartenant au domaine technique des chaînes de blocs. Le réseau de chaînes de blocs comprend des nœuds d'approbation, des nœuds de livre de compte et des nœuds de tri de toutes les parties de transaction de ressources et un terminal de service de chaque partie de transaction de ressources connecté aux divers nœuds. Le procédé est exécuté par un terminal de service d'un demandeur de ressources, et comprend : la mise en cache d'un identifiant d'un ordre de demande de ressources, et l'utilisation régulière de l'identifiant de l'ordre de demande de ressources pour initier une proposition d'approbation aux nœuds d'approbation des différentes parties associées au service ; et la soumission des données associées à une transaction sur la base de l'ordre de demande de ressources au nœud de tri du demandeur de ressources pour effectuer un tri afin d'obtenir un bloc de données de transaction simulée, de façon à amener les nœuds d'approbation à effectuer une vérification de transaction, et une fois la vérification réussie, à stocker les données associées à une transaction au nœud de livre de compte de chaque partie de transaction de ressources. Le procédé peut améliorer de manière efficace la stabilité et la fiabilité d'une transaction de demande de ressources.
