Abstract
(EN)
Methods and network devices for determining a state of an account of interest in a distributed ledger technology (DLT) network are described. The determination of the state of the account of interest is performed based on a DLT state indicator that is a representation of a state of the DLT network that is trusted by the network device. The network device determines whether the DLT state indicator is indicative of the state of the account of interest. Responsive to determining that the DLT state indicator is indicative of the state of the account of interest, the network device retrieves the state of the account of interest based on the DLT state indicator. Responsive to determining that the DLT state indicator is not indicative of the state of the account of interest, the network device performs the following operations: determining a first set of one or more transactions that include the account of interest and executing the first set of transactions to obtain the state of the account of interest.

L'invention concerne des procédés et des dispositifs de réseau servant à déterminer l'état d'un compte d'intérêt dans un réseau à technologie de registre distribué (DLT). La détermination de l'état du compte d'intérêt est effectuée d'après un indicateur d'état de DLT qui est une représentation d'un état du réseau à DLT qui bénéficie de la confiance du dispositif de réseau. Le dispositif de réseau détermine si l'indicateur d'état de DLT est indicatif de l'état du compte d'intérêt. En réaction à une détermination selon laquelle l'indicateur d'état de DLT est indicatif de l'état du compte d'intérêt, le dispositif de réseau récupère l'état du compte d'intérêt d'après l'indicateur d'état de DLT. En réaction à une détermination selon laquelle l'indicateur d'état de DLT n'est pas indicatif de l'état du compte d'intérêt, le dispositif de réseau effectue les opérations suivantes: détermination d'un premier ensemble d'une ou plusieurs transactions qui font intervenir le compte d'intérêt et exécution du premier ensemble de transactions pour obtenir l'état du compte d'intérêt.
