Summary: This work aims to evaluate the storing and retrieving data response time using an Ethereum Smart Contract application to verify the feasibility of its utilization instead of using relational databases in web application development. To achieve the objectives of this work. There was a comparison between the Ethereum Smart Contract and the SQLite, considering response time as the user experience for database choice decisions in future application development. This study consisted of the development of two similar applications. The first one was the Ethereum Smart Contract Application, and the other was the SQLite Application. Using these applications to build graphs of response time behavior as the number of records processed grows. For storing data Blockchain application was much faster than the SQLite application. When retrieving data, the Blockchain application usually starts slower but finishes faster than the SQLite application. Blockchain is a recent technology for secure data storage in a distributed architecture. The hypothesis to be checked was if it also has a good response time compared with other databases. The contribution of this work is to provide information about the efficiency and possible user satisfaction of Blockchain applications.
