Bitcoin emerged as a proposal to revolutionize the current financial system. Due to its reliability, it has become popular and has since caught the attention of governments and world leaders. However, what can cause even more impact, not only in financial matters, is one of its components that gives rigidity and veracity to the information conducted within the application: the protocol blockchain. This mechanism of data storage and processing, compared to an open book, can reinvent the exchange and storage of information on the internet. It is already being used by companies to increase productivity and, mainly, to guarantee security against fraud and external attacks, such as ransomwares. Except for the complexity of technical issues that will not be determined due to the thematic limitation, this study proposes to indicate the use of the protocol blockchain as a possibility of security guarantee of public data also by the public initiative, in order to assure more efficiency of the service provided.
