Abstract

L'invention se rapporte à un Procédé de réduction de la taille d'une base de données répartie de type chaine de blocs, procédé mis en œuvre par un dispositif électronique, appelé nœud, connecté à un ensemble de nœud formant un système de gestion de base de donnée répartie Un tel procédé comprend : - une étape de détermination (10) d'un instant t de création d'un dictionnaire A[t], courant comprenant pour chaque utilisateur de la chaine de blocs, à l'instant t un couple de type (clé, valeur), en fonction d'au moins un paramètre de détermination prédéterminé ; - une étape de création (20), pour ledit instant t de création, du dictionnaire A[t] en fonction d'au moins un paramètre de création prédéterminé, au sein d'une structure de donnée ; - une étape d'obtention (30), à partir du dictionnaire A[t], d'une donnée cryptographique unique DCu, représentative du dictionnaire ; une étape de suppression (40) de blocs de la chaine de blocs en fonction d'au moins un paramètre de suppression prédéterminé.
