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 blockchain-based 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.

区块链根据分布式交易和处理基于哈希的微小块的原理工作。位于区块链中的数据可保持其完整性和透明度，从而使参与者能够对其进行验证。如今，人们将区块链技术应用于必须维护数据完整性的领域。但是，由于技术的复杂性和由此带来的效率低下，人们可能不愿意引入区块链技术。这项工作提出了一种基于DEVS的实验方法，用于评估基于区块链的服务的性能。通过使用以太坊区块链框架实施内容交付服务来测试实验方法。作为评估结果，我们显示了服务的总周转时间，并调查了组成该服务的智能合约功能的延迟。此外，评估结果显示了基于区块链的服务和基于数据库的服务之间的性能差异。这项工作提出了一种评估区块链服务性能的方法，并展示了实验结果，可供计划实施基于区块链服务的人们参考。
