Abstract

L'invention se rapporte à un procédé de conversion de jeton en fonction d'une chaîne de blocs publique et à un système de chaîne de blocs. Dans l'utilisation pratique, une pluralité de chaînes d'approvisionnement fournissent une transaction d'approvisionnement à une chaîne de blocs publique, les jetons d'approvisionnement sont convertis en jetons de chaîne de blocs publique de valeur égale, et la chaîne de blocs publique stocke et enregistre la quantité d'approvisionnement des jetons d'approvisionnement reçus ; une chaîne de conversion fournit une transaction de conversion à la chaîne de blocs publique, la chaîne de blocs publique calcule le taux de conversion en fonction de la quantité d'approvisionnement de jetons initiaux et de jetons de conversion, extrait des jetons de conversion ayant une valeur égale en tant que jetons initiaux des jetons d'approvisionnement stockés, et transfère à la chaîne de conversion. Dans le procédé, le taux de conversion entre deux types de jetons est calculé au moyen de la chaîne de blocs publique, ce qui permet de fournir un environnement de conversion relativement objectif. Après qu'une transaction d'approvisionnement a lieu, les jetons d'approvisionnement sont stockés au moyen de la chaîne de blocs publique de telle sorte que la chaîne de conversion ne traite qu'avec la chaîne de blocs publique pendant la transaction de conversion et qu'il n'est pas nécessaire d'entrer en contact avec les contreparties de conversion, ce qui permet d'éviter une participation centralisée de programme ou de plate-forme et d'améliorer l'efficacité de conversion.
