| Abstract(in English) | In recent years, the use of blockchain has progressed in various industries, and the need for cooperation between systems using blockchain has increased. When linking, if linking is performed via an application, the problems are that it becomes difficult to ensure the transparency of processing and that a single trust point is created. On the other hand, when the blockchains are directly linked with each other, each node participating in the linking source blockchain calls the linking destination blockchain by mutual verification of the processing contents, which is a characteristic of the blockchain. The problem is that the same processing is executed unnecessarily. In this study, we proposed the Proxy-typed elimination technology of duplicate processing that realizes cooperation between blockchain systems based on the identification information of processing.We developed and evaluated the cooperation from the system that handles the transaction information of the product to the system that handles the payment information of the product. As a result of the evaluation, we confirmed the feasibility of cooperation between blockchain systems that can ensure the transparency of processing and does not cause unnecessary duplicate processing. In addition, it was confirmed that the processing performance related to cooperation can be improved by eliminating duplicate processing. |
