Title (EN) MANAGEMENT OF SNAPSHOT IN BLOCKCHAIN
(FR) GESTION D'INSTANTANÉ DANS UNE CHAÎNE DE BLOCS
Abstract:
(EN) Verified snapshots are generated by obtaining, from one of a plurality of first nodes, a difference between a common data at a first time point and the common data at a second time point that is different from the first time point, generating a first snapshot of the common data at the first time point based on the difference, obtaining a hash of the common data at the first time point from one of the plurality of first nodes, and verifying the first snapshot at the first time point with the hash of the common data at the first time point.
(FR) La présente invention concerne des instantanés vérifiés qui sont produits par obtention, à partir d'un premier nœud d'une pluralité de premiers nœuds, d'une différence entre des données communes à un premier moment et les données communes à un second moment différent du premier moment, produisant un premier instantané des données communes au premier moment sur la base de la différence, obtenant un hachage des données communes au premier moment à partir d'un nœud de la pluralité de premiers nœuds, et vérifiant le premier instantané au premier moment au moyen du hachage des données communes au premier moment.
