Abstract
(EN)
Systems and methods for token vault synchronization using a distributed ledger are disclosed. In one embodiment, in a distributed token ledger network comprising a plurality of nodes, each node associated with a token ledger and comprising at least one computer processor, a method for token vault synchronization using a distributed ledger may include: (1) a node receiving a lifecycle event for a payment token; (2) the node writing the lifecycle event to a token ledger for the node; (3) committing the lifecycle event to the distributed token ledger after the plurality of nodes in the distributed token ledger agree to committal; (4) a watcher at the node detecting the commitment of the lifecycle event to the distributed token ledger; and (5) the watcher communicating the lifecycle event to a non-node participant.

L'invention concerne des systèmes et des procédés de synchronisation d'une chambre forte de jetons à l'aide d'un registre distribué. Dans un mode de réalisation, dans un réseau à registre de jetons distribué comprenant une pluralité de nœuds, chaque nœud étant associé à un registre de jetons et comprenant au moins un processeur informatique, un procédé de synchronisation d'une chambre forte de jetons à l'aide d'un registre distribué peut comprendre : (1) la réception par un nœud d'un événement de cycle de vie correspondant à un jeton de paiement; (2) l'écriture par le nœud de l'événement de cycle de vie dans un registre de jetons propre au nœud; (3) la validation de l'événement de cycle de vie dans le registre de jetons distribué après que la pluralité de nœuds dans le registre de jetons distribué ont accepté la validation; (4) la détection, par un observateur au niveau du nœud, de la validation de l'événement de cycle de vie dans le registre de jetons distribué; et (5) la communication par l'observateur de l'événement de cycle de vie à un participant sans nœud.
