Title (EN) DECENTRALIZED SAFEGUARD AGAINST FRAUD
(FR) PROTECTION DÉCENTRALISÉE CONTRE LA FRAUDE
Abstract:
(EN) A method includes acquiring, at a node server, blockchain data for a blockchain address on a blockchain network. The blockchain data includes a plurality of transactions for the blockchain address. The method includes generating a local node trust score for the blockchain address based on the blockchain data. The local node trust score indicates a likelihood that the blockchain address is involved in fraudulent activity. The method includes receiving, from a plurality of remote servers, a plurality of additional local trust scores for the blockchain address. The method includes determining a consensus trust score based on the local node trust score and the plurality of additional local trust scores. Additionally, the method includes receiving a trust request for the blockchain address from a requesting device and sending the consensus trust score for the specified blockchain address to the requesting device.
(FR) Procédé consistant à acquérir, au niveau d'un serveur de nœuds, des données de chaîne de blocs pour une adresse de chaîne de blocs sur un réseau de chaîne de blocs. Les données de chaîne de blocs comprennent une pluralité de transactions pour l'adresse de chaîne de blocs. Le procédé consiste à générer un score de confiance de nœud local pour l'adresse de chaîne de blocs sur la base des données de chaîne de blocs. Le score de confiance du nœud local indique une probabilité que l'adresse de la chaîne de blocs soit impliquée dans une activité frauduleuse. Le procédé consiste à recevoir, en provenance d'une pluralité de serveurs distants, une pluralité de scores de confiance locaux supplémentaires pour l'adresse de chaîne de blocs. Le procédé consiste à déterminer un score de confiance de consensus sur la base du score de confiance de nœud local et de la pluralité de scores de confiance locaux supplémentaires. De plus, le procédé consiste à recevoir une demande de confiance pour l'adresse de chaîne de blocs provenant d'un dispositif demandeur et à envoyer le score de confiance de consensus pour l'adresse de chaîne de blocs spécifiée au dispositif demandeur.
