Uma metodologia para suporte à tomada de decisão quanto ao uso de blockchain na área de registros públicos

Abstract

The emergence of Bitcoin and Blockchain technology has changed the world of ecommerce. These technologies have the potential to one day become the standard for Web applications, through decentralized applications. Decentralized applications are flexible, transparent, distributed, resilient applications and have greater growth power, in terms of scalability and availability, when compared to the current software model (clientserver architecture). There are limitations that prevent the use of Blockchain technology for solving problems involving data and information distribution. Because there are limitations, designers and enthusiasts who are not well educated about the technology can make mistakes and use it in a way that damages the solution to which it belongs, in addition to preventing it from reaching its fullness. Due to the possibilities that Blockchain technology and decentralized applications bring, this work aims to design a methodology to assist in decision making regarding the use of Blockchain for the government environment, specifically in the area of public records. To exemplify the application of the methodology, a case study was carried out using the service of registration and consultation of registries in notaries, which service is supported by a system provided by the National Council of Justice. As a result, it was possible to demonstrate that the methodology process creates an implementation profile for Blockchain technology, a profile that allows the system designer to choose and configure Blockchain platforms for the desired purpose. The process result indicates that the Blockchain technology is suitable for the purpose of notary service, ensuring the proper use of technology and avoiding possible losses.
