Desarrollo de una aplicación descentralizada con el uso de la tecnología Blockchain para votaciones electrónicas en la Cooperativa de Ahorro y Crédito “Nueva Esperanza"

Abstract

The objective of the present curricular integration work was to implement a decentralized application of electronic voting for the "Nueva Esperanza" Savings and Credit Union. Analytical, deductive and statistical methods were used as data collection techniques; The documentation review, the Business Process Model and Notation (BPMN) diagram, a survey adapted to the Security questionnaire with a focus on Objective, the Goal Question Metric (GQM) and metrics to evaluate the use of resources were used. Regarding the tools, the Visual Studio Code and Remix IDE code editor, JavaScript programming language, was used for both the development of the Backend and Frontend; Solidity language was used for the development of the smart contract and PostgreSQL was used for the database. The development methodology of the Rational Unified Process (RUP) and the Unified Modeling Language (UML) were used during the application development cycle to work with users in the definition of use cases and requirements, achieving a cycle of iterative and incremental life. In addition, the ISO/IEC 25010 standard was applied to measure the efficiency of performance and security of the system. The results obtained, in terms of performance efficiency, average a satisfactory degree, while the security level is 94%. It is concluded that the system meets the different customer requirements. It is recommended to promote the use of standards to ensure the quality of the process and the software product.
