(EN) BLOCKCHAIN MANAGEMENT SYSTEM
(FR) SYSTÈME DE GESTION DE CHAÎNE DE BLOCS
Abstract
(EN)
According to one or more aspects of the present disclosure, operations may include obtaining a token transaction request of a token transaction that includes a transfer of assignment of a crypto-token of a crypto-medium from a first entity to a second entity. The token transaction request may be a request to initiate the token transaction. The operations may further include generating a transaction signature in response to obtaining the token transaction request. The operations may include validating the token transaction using the digital signature and blocks of a private blockchain that includes a blockchain record of all transactions of the crypto-medium. In these or other embodiments, the operations may include generating a new block for the private blockchain, the new block including an update to the blockchain record that indicates the token transaction details. The generating of the new block may be triggered by the token transaction being validated.

Selon un ou plusieurs aspects de la présente invention, des opérations peuvent consister à obtenir une demande de transaction par jeton d'une transaction par jeton qui comprend un transfert d'attribution d'un jeton de cryptographie d'un milieu de cryptographie d'une première entité à une seconde entité. La demande de transaction par jeton peut être une demande d'initiation de la transaction par jeton. Les opérations peuvent en outre consister à générer une signature de transaction en réponse à l'obtention de la demande de transaction par jeton. Les opérations peuvent consister à valider la transaction par jeton à l'aide de la signature numérique et des blocs d'une chaîne de blocs privée qui comprend un enregistrement de chaîne de blocs de toutes les transactions du milieu de cryptographie. Dans ces modes de réalisation ou d'autres modes de réalisation, les opérations peuvent consister à générer un nouveau bloc destiné à la chaîne de blocs privée, le nouveau bloc comprenant une mise à jour de l'enregistrement de chaîne de blocs qui indique les détails de transaction par jeton. La génération du nouveau bloc peut être déclenchée par la transaction par jeton qui est validée.
