Abstract

Procédé de migration d’une chaîne de blocs à remplacer, dite première chaîne de blocs, vers une chaîne de blocs de remplacement, dite deuxième chaîne de blocs. Le procédé de migration comprend : une initialisation de la deuxième chaîne de blocs, l’initialisation comprenant une génération, dans une chaîne de blocs principale configurée pour superviser l’accès aux première et deuxième chaînes de blocs, d’une zone de supervision de la deuxième chaîne de blocs configurée pour stocker des droits utilisateurs sur la deuxième chaîne de blocs; une inscription d’un ou plusieurs utilisateurs auprès de la deuxième chaîne de blocs, l’inscription d’un utilisateur comprenant un enregistrement dans un annuaire d’utilisateurs dans la chaîne de blocs principale d’une adresse secondaire allouée à cet utilisateur pour la connexion à la deuxième chaîne de blocs; une génération dans la deuxième chaîne de blocs d’un ensemble de blocs de données correspondant à une image de la première chaîne de blocs; un enregistrement de nouvelles transactions à la fois dans la première chaîne de blocs et dans la deuxième chaîne de blocs pendant une période dite période miroir ; un basculement de tout ou partie des utilisateurs de la première chaîne de blocs vers la deuxième chaîne de blocs de sorte à interdire l’enregistrement de transactions au nom de ces utilisateurs dans la première chaîne de blocs et autoriser l’enregistrement de transactions au nom de ces utilisateurs dans la deuxième chaîne de blocs. Figure pour l’abrégé : Fig. 4BA process for migrating a chain of blocks to be replaced, referred to as the first chain of blocks, to a chain of replacement blocks, referred to as the second chain of blocks. The migration method comprises: an initialization of the second blockchain, the initialization comprising a generation, in a main blockchain configured to supervise the access to the first and second blockchains, of a supervision area of the second blockchain configured to store user rights on the second blockchain; a registration of one or more users with the second blockchain, the registration of a user comprising a registration in a user directory in the main blockchain of a secondary address allocated to this user for connection to the second chain of blocks; generating in the second blockchain a set of data blocks corresponding to an image of the first blockchain; recording new transactions both in the first blockchain and in the second blockchain during a so-called mirror period; switching all or part of the users from the first blockchain to the second blockchain so as to prohibit the recording of transactions on behalf of these users in the first blockchain and allow the recording of transactions on behalf of these users in the second blockchain. Figure for the abstract: Fig. 4B
