Abstract

Système de gestion d'adresses à base de chaînes publiques, comprenant une chaîne publique et une sous-chaîne ou une chaîne de blocs tierce reliée à la chaîne publique, une partie des nœuds de la chaîne publique étant configurée pour être des nœuds de gestion d'adresses pour stocker et synchroniser toutes les données d'adresses de nœud dans la chaîne publique et la sous-chaîne ; lorsqu'une transaction se produit, les nœuds de gestion d'adresses peuvent recevoir une transaction d'interrogation d'adresses ; et des données d'adresses correspondant à un nœud cible de transaction sont envoyées. Dans le présent système, une partie de nœuds dans une chaîne publique est configurée pour être des nœuds de gestion d'adresse, qui peuvent permettre à un nœud d'initiation de transaction d'obtenir rapidement l'adresse d'un nœud cible de transaction. Par conséquent, dans le nœud d'initiation de transaction, il n'est pas nécessaire de stocker les informations d'adresse de tous les nœuds, et le processus d'obtention de l'adresse du nœud cible de transaction se produit uniquement entre le nœud d'initiation de transaction et les nœuds de gestion d'adresses sans avoir besoin d'obtenir l'adresse du nœud cible de transaction au moyen d'une transaction de diffusion, ce qui peut réduire de manière significative l'occupation de la bande passante de réseau et améliorer l'efficacité de la transaction.
