Abstract

L'invention concerne des dispositifs informatiques et des procédés de vérification d'une transaction d'actif numérique par une pluralité de nuds dans un réseau à chaîne de blocs. La pluralité de nuds peut comprendre des fragments de clé privée respectifs. Le dispositif informatique peut être configuré pour : recevoir une demande de mise à jour d'une charge associée à un actif numérique; générer une transaction de chaîne de blocs proposée sur la base de la demande de mise à jour de la charge, la diffusion de la transaction de chaîne de blocs proposée pouvant être basée sur une clé privée reconstituée sur la base d'une pluralité de fragments de clé privée reçus en provenance d'au moins un autre nud; recevoir une pluralité de fragments de clé privée de la part d'au moins un autre nud pour une combinaison en tant que clé privée collective; déterminer que la clé privée collective correspond à la clé privée reconstituée d'un quorum; et générer un signal pour initier la propagation de la transaction de chaîne de blocs proposée à un registre électronique du réseau à chaîne de blocs.
