Abstract

Un mode de réalisation de la présente invention concerne un procédé de traitement d'informations basé sur un protocole de consensus, pouvant être réalisé dans une chaîne de blocs. Le procédé peut être appliqué à la vérification de transactions. Le procédé consiste : à recevoir une instruction d'ajout d'informations envoyée par une partie de gestion d'informations ; si l'instruction d'ajout d'informations est une instruction valide, à ajouter, en réponse à l'instruction d'ajout d'informations, des informations d'identifiant d'interception à un premier protocole de consensus pour obtenir un second protocole de consensus ; suite à la réception d'informations à traiter qui sont envoyées par une partie d'envoi d'informations, à déterminer, sur la base du second protocole de consensus, si les informations appartiennent à un type d'informations à intercepter ; et si tel est le cas, à intercepter les informations sur la base du second protocole de consensus. Le mode de réalisation de la présente invention permet d'intercepter des informations d'un type d'informations à intercepter sur la base d'un protocole de consensus, ce qui permet d'améliorer le traitement d'informations et de fournir une large applicabilité.
