Title (EN) VERIFICATION OF INTERACTIONS SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE VÉRIFICATION D'INTERACTIONS
Abstract:
(EN) A system and method is disclosed. The method comprises a client device receiving a verification request comprising an interaction identifier. The client device can then query a full node for a random sampling of block headers from the full node. The client device can receive the random sampling of block headers from the full node, and verify the random sampling of block headers. The client device can then determine that the blockchain maintained by the full node is valid after verifying the random sampling of block headers.
(FR) La présente invention concerne un système et un procédé. Le procédé comprend un dispositif client qui reçoit une demande de vérification contenant un identifiant d'interaction. Le dispositif client peut : interroger un nœud complet en vue d'un échantillonnage aléatoire d'en-têtes de blocs provenant du nœud complet ; recevoir puis vérifier l'échantillonnage aléatoire d'en-têtes de blocs provenant du nœud complet ; et après vérification de l'échantillonnage aléatoire d'en-têtes de blocs, déterminer que la chaîne de blocs gérée par le nœud complet est valable.
