Abstract

La présente invention concerne un système et un procédé de transmission de données. Le système comprend un client, un serveur, un réseau de communication de relais de chaîne de blocs, et un premier mandataire et un second mandataire qui sont connectés au réseau de communication de relais de chaîne de blocs. Le client est utilisé pour envoyer un message d'accès au premier mandataire, le message d'accès comprenant un identifiant du serveur. Le premier mandataire est utilisé pour déterminer les informations d'adresse du second mandataire sur la base d'une première correspondance et de l'identifiant du serveur contenu dans le message d'accès, et envoyer le message d'accès au second mandataire via le réseau de communication de relais de chaîne de blocs selon les informations d'adresse du second mandataire. Le second mandataire est utilisé pour déterminer les informations d'adresse du serveur sur la base d'une seconde correspondance et de l'identifiant du serveur contenu dans le message d'accès, et envoyer le message d'accès au serveur selon les informations d'adresse du serveur. Le serveur est utilisé pour recevoir et traiter le message d'accès.
