Having its first applications in cryptocoins, today the technology is being tested in several public and private environments, from the health and education area to voting systems. Taking the last example, blockchain technology helps reduce voter dissatisfaction and distrust with existing voting methods. This work aimed to create an online election system using blockchain and make a comparative analysis between the proposed system and another one made in traditional client-server modeling. Design Science Research (DSR) methodology was used to conduct this work. In addition, the Hyperledger Fabric framework and the Hyperledger Composer toolkit were used to create the blockchain network.Acesso AbertoSistemas de InformaçãoTecnologia BlockchainSistema de eleições onlineHyperledger Fabric e Composer – FerramentaDistributed ledger technology – ElectionTrabalho de Conclusão de CursoCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::METODOLOGIA E TECNICAS DA COMPUTACAO::SISTEMAS DE INFORMACAO
