| Abstract(in English) | Data trading services, which connect data providing companies and data utilization companies and support corporate growth through data distribution, are attracting attention, while many companies are reluctant to data trading. Many of the current data trading services rely on the trust of the data trading service provider, and it is important to ensure the transparency of the transaction process. Blockchain is attracting attention as a promising technology for solving this kind of problem. When blockchain was applied to the management of transaction log to solve the above problem, it was found that the throughput required for data transaction in actual service was not obtained. Therefore, we proposed a method to reduce the time required for storing transaction logs by integrating and executing multiple transaction log storage requests, and developed and evaluated a blockchain-based transaction log storage technology that applied the proposed method. In the evaluation, it was confirmed that the transaction log storage in the blockchain could be completed without being proportional to the number of requests, indicating the feasibility of a data transaction service that secured the transparency of the transaction process. |
