Abstract

L’invention concerne un procédé pour permettre à un utilisateur (1) d’accéder à une chaîne de blocs d’une organisation, ledit procédé prévoyant de : créer une paire de clés privée (9a) et publique (9b) pour permettre audit utilisateur d’effectuer des signatures cryptographiques durant une participation à une fonction opérationnelle dans la chaîne de blocs ; collecter des données personnelles de l’utilisateur (1), lesdites données comprenant au moins une information sur l’identité de l’utilisateur (1) et une information sur ladite organisation ; vérifier la validité desdites données personnelles ; identifier un statut dudit utilisateur au sein de ladite organisation au moyen desdites données vérifiées ; enregistrer la clé publique (9b) dans au moins un coffre-fort numérique de la chaîne de blocs en fonction dudit statut identifié, afin de permettre audit utilisateur de participer à au moins une fonction opérationnelle dans ladite chaîne de blocs accessible par ledit coffre-fort.
