Abstract

La présente invention concerne un procédé de recherche de données de chaîne de blocs. Ledit procédé comprend les étapes consistant à : A, au moyen d'une interface au protocole de transfert hypertexte, recevoir une demande de lecture de page Web envoyée par un moteur de recherche, la demande de lecture de page Web contenant un premier localisateur uniforme de ressources (URL) et un numéro de version ; B, au niveau du premier URL, acquérir des données historiques de chaîne de blocs correspondant au numéro de version ; C, déterminer s'il existe au moins un second URL, les secondes données de chaîne de blocs au niveau dudit au moins un second URL étant associées aux premières données de chaîne de blocs ; D, si ledit au moins un second URL existe, en fonction des données historiques de chaîne de blocs et dudit au moins un second URL, générer une page Web associée au premier URL ; et E, au moyen de l'interface au protocole de transfert hypertexte, renvoyer la page Web au moteur de recherche.
