Algumas instituicoes de ensino, como o Massachusetts Institute of Technology e a Holberton School, em San Francisco (EUA), utilizam a blockchain publica da Bitcoin para manter e validar seus certificados, porem, mediante pagamento de taxas. A implementacao de Blockchain adotada para esse projeto foi a Multichain, solucao que, por ser codigo aberto, diminui custos de implantacao, propicia facilidade de instalacao e manutencao de sua infraestrutura e dispensa cobrancas de quaisquer taxas ou valores para armazenamento de informacoes, o que a torna adequada perante o carater publico da Universidade Federal do Tocantins. Por conta de suas carac...

It aims to identify the main challenges found in their usage, its trends and application. This computing model, although not new, has a considerable amount of users that operate in several areas. As a model that allows the use of heterogeneous computing environments, computational grids have many issues to consider for their use. This decentralized processing also allows their use to be adapted and improved by newer technologies. The findings of this study may provide insights for researchers and users on architecture improvements and computational grids usage possibilities. I.INTRODUCTION The Internet growth, powerful computers availability, high-speed computer networks just as the low cost of components raw materials, is changing the way that scientists and engineers do computing and also the way society in general manages information and services [23]. In 90...
