Aplicação tecnologia Blockchain em sistema de votação online

Abstract

The present work addresses the problem of the lack of security and integrity in voting processes, especially in contexts where fraud and manipulation can compromise the credibility of electoral results. The motivation behind this study lies in the growing demand for more transparent and reliable electoral methods, particularly within academic organizations and small institutions, where trust in the process is crucial. The main objective of this work is to develop a prototype of an online voting system using Blockchain technology, which ensures the immutability of votes, the transparency of the process, and the trust of voters. To achieve this objective, the Laravel framework was used for the development of the prototype, and Blockchain was employed for the secure storage of votes, ensuring that they remain inviolable after submission. The methodology adopted included the creation of a system that manages the entire electoral process, from the registration of voters and candidates, through the actual voting process, to the counting and verification of votes. The system integrates Blockchain as a means of ensuring that each vote is unique and permanently recorded, without the possibility of manipulation or deletion. As a result, the prototype demonstrated that Blockchain technology can be effectively applied to online voting systems, providing a high level of security and data integrity in the electoral process. The implications of this study suggest that the adoption of Blockchain in electoral processes, especially in small and medium-sized contexts, can represent a significant advancement in ensuring fair and transparent elections.
