Abstract

La présente invention concerne la technologie des chaînes de blocs, et porte sur un procédé et un appareil d'attribution de permissions pour des nœuds dans un réseau de chaînes de blocs, sur un dispositif informatique, et sur un support. Le procédé peut comprendre : la notation du nœud courant sur la base de caractéristiques de transaction entre le nœud courant et d'autres nœuds dans le réseau de chaînes de blocs pour obtenir des résultats de notation de tous les nœuds y compris le nœud courant ; la construction d'une matrice de notation à l'aide des résultats de notation ; le réglage d'un poids, de telle sorte que la plage numérique de chaque élément dans la matrice de notation s'inscrive dans une plage prédéfinie ; l'exécution d'une opération sur les colonnes sur la matrice de notation courante, de façon à convertir la matrice de notation courante en un ensemble de notation unidimensionnel servant à représenter des valeurs d'attribut de comportement ; et l'attribution des permissions pour les nœuds dans le réseau de chaînes de blocs en fonction des valeurs d'attribut de comportement. Des données telles qu'une table d'enregistrement de permissions et la matrice de notation peuvent être stockées dans une chaîne de blocs. Selon la présente invention, les permissions des nœuds dans le réseau de chaînes de blocs peuvent être attribuées raisonnablement sur le principe d'éviter une intervention humaine, de manière à réaliser une gestion équitable pour le réseau de chaînes de blocs, et l'expérience utilisateur sur les nœuds est très bonne.
