Abstract

L'invention se rapporte à un procédé de stockage de données basé sur une chaîne de blocs, à un dispositif associé et à un support d'informations. Le procédé comprend les étapes suivantes : un nœud cible acquiert le numéro de série d'un premier bloc récemment généré diffusé dans un système de chaîne de blocs, le nœud cible étant l'un quelconque d'une pluralité de nœuds, le premier bloc comprenant des données de bloc et une tête de bloc et la tête de bloc comprenant le numéro de série du premier bloc ; le nœud cible acquiert une première valeur de départ de jeton, la première valeur de départ de jeton étant générée en fonction du nombre de nœuds du système de chaîne de blocs ; et le nœud cible détermine le stockage du premier bloc ou le stockage de la tête de bloc du premier bloc sur la base d'une première valeur de jeton du nœud cible, du numéro de série du premier bloc et de la première valeur de départ de jeton de telle sorte que la pression de stockage de données du nœud cible dans le système de chaîne de blocs peut être efficacement atténuée.
