La présente invention se rapporte au domaine technique du traitement de données, et concerne en particulier un procédé et un système de traitement de données point à point, un dispositif informatique et un support de stockage. Dans le procédé de traitement de données point à point, un grand livre général est associé à tous les grands livres auxiliaires au moyen d'indices de hachage ; lorsqu'une opération de transaction d'un grand livre auxiliaire est déclenchée, la légitimité d'une transaction du grand livre auxiliaire est contrôlée au moyen du grand livre général ; et lorsque la transaction est légitime, le montant pour le grand livre auxiliaire et le montant pour le grand livre général sont mis à jour, le grand livre général et le grand livre auxiliaire sont incités à stocker l'enregistrement de transaction courant, et le grand livre général est invité à mettre à jour une table d'indices de hachage. Sur cette base, le grand livre général stocke uniquement l'entrée de transaction la plus récente du grand livre auxiliaire et un indice de hachage correspondant, et ne stocke pas un grand livre de journal de transactions pour le grand livre auxiliaire, et le grand livre de journal de transactions est stocké dans le grand livre auxiliaire et conservé par un utilisateur lui-même, de manière à réaliser une structure de grand livre partagé unique pour un paiement point à point, à réaliser l'efficacité de traitement de données de paiement centralisées et les caractéristiques d'un grand livre de chaîne de blocs, et à pouvoir prendre en considération aussi bien la sécurité de traitement de données de paiement que l'efficacité de traitement des données de paiement.
