Decide Brasil : uma plataforma integrada WEB e app com Blockchain e contratos inteligentes para votação e acompanhamento do orçamento participativo

Abstract

Participatory Budgeting (PB) is a process that allows citizens to participate directly in the allocation of public resources. Traditionally, this is done through face-to-face assemblies, but this method has several limitations. To overcome these limitations, the Decide Brasil platform was developed, bringing the PB into the digital environment through blockchain technology and smart contracts. This created a secure, transparent and accessible environment for citizen participation. With the Decide Brasil Citizen app, citizens can submit proposals, vote and monitor the implementation of projects. With the Decide Brasil Manager web system, administrators can consolidate and manage the community on this digital platform. The blockchain technology guarantees the integrity and immutability of the information, increasing the reliability of the process and reducing the possibility of corruption. The platform was developed based on an analysis of existing solutions and scientific studies, with the aim of promoting citizen participation, transparency and effectiveness in the management of public resources. The result was a platform that transformed the way participatory budgeting is managed, making it more efficient, transparent and accessible to all citizens. Based on the results of the usability tests structured according to the System Usability Scale (SUS), the Decide Brasil Cidadão app obtained an average score of 72.5 points, receiving a C+ rating on the grading scale. It was rated "Good" in terms of adjectives, considered "Acceptable" in terms of acceptability and classified as "Passive" in the Net Promoter Score (NPS). The Decide Brasil platform is the first Brazilian digital platform to implement participatory budgeting in digital format, using an innovative technology, blockchain, in its production.
