Abstract

L'invention concerne un procédé et un système de vérification de transaction basés sur une chaîne de blocs, un dispositif électronique et un support. Le procédé comprend les étapes suivantes : lorsqu'un nœud sur une chaîne de blocs traite une transaction, déchiffrer un solde d'origine de chaque partie à la transaction, calculer le solde d'origine de chaque partie à la transaction pour obtenir un nouveau solde, chiffrer le nouveau solde de chaque partie à la transaction pour obtenir de nouveaux soldes chiffrés, et diffuser chaque nouveau solde chiffré à chaque nœud de la chaîne de blocs au moyen d'un contrat intelligent (S10); lorsque le nœud de la chaîne de blocs reçoit le nouveau solde chiffré diffusé correspondant à chaque partie à la transaction, démarrer un contrat intelligent correspondant pour effectuer une vérification de numéro composite (S20); si la vérification de numéro composite réussit, le contrat intelligent correspondant à chaque nœud sur la chaîne de blocs met à jour ses propres données selon le nouveau solde chiffré correspondant à chaque partie à la transaction (S30); solliciter un système de vérification d'équilibre négatif externe prédéfini de la chaîne de blocs pour démarrer une pluralité de fils, chaque fil étant responsable de la réalisation d'une vérification d'équilibrage négatif sur l'équilibre d'un compte unique de chaque nœud sur la chaîne de blocs (S40). Selon le procédé, on peut vérifier si la transaction est normale ou non, et la vitesse de traitement de transaction sur la chaîne de blocs peut également être garantie dans le cas où un surdébit de système n'est pas occupé.
