Abstract
Education generates a considerable amount of data and information, it is necessary to manage this data securely, avoiding problems of falsification and tampering with diplomas, certificates, and other important student documents. In addition, distance learning is becoming more popular due to the Covid-19 pandemic period, where courses are offered in virtual learning environments such as Moodle. Blockchain technology can be used as a tool to ensure the security of data managed by Moodle. However, there is a gap in current state-of-the-art solutions for integrating these data with Blockchain platforms. This work proposes BlockMoodle, a solution developed to integrate Moodle with Blockchain Ethereum. This work also performs an analysis of the financial cost of using the tool. In addition, a performance evaluation of the proposed solution is also carried out considering different usage scenarios. Finally, the conclusions and future work to be developed are presented.

Blockchain has emerged to provide security and reliability in the financial negotiations that took place on the Internet (Nakamoto, 2008)
This section aims to evaluate the main contribution of this article, BlockMoodle. 6.1 Financial cost assessment
This work aimed to present a proposal for the integration of the Virtual Learning Environment Moodle to the Ethereum Blockchain, through the creation of the BlockMoodle solution
Summary
Blockchain has emerged to provide security and reliability in the financial negotiations that took place on the Internet (Nakamoto, 2008). Interest began to emerge in its use in other relevant areas. A well-known problem refers to security in the management of students’ school records, such as grades history and certificates. With the popularization of the Internet, the distance learning modality has become increasingly accessible to a considerable number of students. Distance Learning uses Virtual Learning Environments (VLE) to make course content available to students and to support interaction between students and teachers. For example, the creation and management of courses, activities, and questionnaires. Moodle facilitates communication between students and teachers through forums and messages
