PROCÉDÉ, SYSTÈME ET PRODUIT-PROGRAMME D'ORDINATEUR PERMETTANT DE DÉTERMINER LA SOLVABILITÉ D'UN ÉCHANGE D'ACTIFS NUMÉRIQUES
Abstract:
(EN)
Disclosed is a system, method, and computer program product for determining solvency of a digital asset exchange system. The method includes identifying a plurality of blockchain addresses corresponding to a plurality of users of the digital asset exchange system, generating a first commitment to an amount of digital assets corresponding to the plurality of blockchain addresses, generating a second commitment to a balance of each user of the plurality of users, generating a first component of a zero-knowledge algorithm configured to receive, as input, the first commitment, and to output a value generated based on each public key, generating a second component of the zero-knowledge algorithm configured to receive, as input, the second commitment, and to output a value generated based on each user balance, and determining, with at least one processor, that the digital asset exchange system is solvent based on the zero-knowledge algorithm.
(FR)
L'invention concerne un système, un procédé et un produit-programme d'ordinateur permettant de déterminer la solvabilité d'un système d'échange d'actifs numériques. Le procédé consiste à : identifier une pluralité d'adresses de chaîne de blocs correspondant à une pluralité d'utilisateurs du système d'échange d'actifs numériques ; générer un premier engagement envers une quantité d'actifs numériques correspondant à la pluralité d'adresses de chaîne de blocs ; générer un second engagement envers un solde de chaque utilisateur de la pluralité d'utilisateurs ; générer un premier composant d'un algorithme à connaissance nulle configuré pour recevoir le premier engagement en tant qu'entrée et transmettre une valeur générée d'après chaque clé publique ; générer un second composant de l'algorithme à connaissance nulle configuré pour recevoir le second engagement en tant qu'entrée et transmettre une valeur générée d'après chaque solde d'utilisateur ; et déterminer, à l'aide d'au moins un processeur, que le système d'échange d'actifs numériques est solvable d'après l'algorithme à connaissance nulle.
