Abstract
En 中文
Blockchain works according to the principles of distributed transactions and processing tiny hash based blocks. Data located in the blockchain preserves its integrity and transparency, which enables participants to verify it. Today, people apply blockchain technology in domains that must maintain the integrity of the data. However, people can be reluctant to introduce blockchain technology due to the complexity of the technology and the resultant inefficiency. This work presents a DEVS-based experimental methodology for performance evaluation of blockchainbased services. The experimental methodology is tested by implementing a content delivery service by utilizing the Ethereum blockchain framework. As the evaluation result, we show the overall turnaround time of the service and investigate the delay of smart contract function consisting the service. In addition, the evaluation result shows the difference in performance between blockchain-based and database-based services. This work presents a methodology for evaluating blockchain service performance and shows experimental results that can be referenced by people who are planning to implement blockchain-based services.
