Title
(EN) DISTRIBUTED, CENTRALLY AUTHORED BLOCK CHAIN NETWORK
(FR) RÉSEAU À TECHNOLOGIE BLOCKCHAIN (CHAÎNE DE BLOCS) DISTRIBUÉ, À CONCEPTION CENTRALE
Abstract
(EN)
A central service provider manages and writes transaction details to a private block chain network. Blocks of transaction records written onto the block chain by the central service provider are distributed to members of the block chain, thereby enabling data resiliency and self-verifiability. As the full block chain is available to members of the block chain network, the central service provider also ensures the privacy of transaction details by providing an assembled header and encrypted block of transaction records that are generated using a combination of symmetric and asymmetric cryptographic techniques. Altogether, the full block chain network is distributed across members of the block chain, but the members can only access and read transaction details in the block chain that they are authorized to view.
(FR)
L'invention concerne un fournisseur de services central qui gère et écrit des détails de transaction sur un réseau blockchain privé. Des blocs d'enregistrements de transaction écrits sur la chaîne de blocs par le fournisseur de services central sont distribués à des membres de la chaîne de blocs, ce qui permet d'obtenir une résilience et une auto-vérification de données. Comme des membres du réseau blockchain ont accès à la totalité de la chaîne de blocs, le fournisseur de services central garantit également la confidentialité des détails des transactions en fournissant un en-tête assemblé et un bloc chiffré d'enregistrements de transaction qui sont générés à l'aide d'une combinaison de techniques cryptographiques symétriques et asymétriques. En outre, le réseau blockchain est intégralement distribué entre les membres de la chaîne de blocs, mais les membres ne peuvent accéder et lire que les détails de transactions dans la chaîne de blocs qu'ils sont autorisés à visualiser.
