Abstract(s)
A tecnologia blockchain tem apresentado uma crescente tendência de aplicabilidade em
diversos setores da indústria. O seu funcionamento assenta num sistema de informação
descentralizado e prima pela considerável performance e elevada segurança.
Este projeto, realizado num contexto académico, pretende promover conhecimento acerca da
tecnologia blockchain, e como esta juntamente com os smart contracts podem ser utilizados
em sistemas industriais com múltiplos participantes, preservando as relações de mutualismo.
Para tal, elaborou-se uma investigação cuidada dos conceitos da tecnologia, de casos
industriais reais da sua utilização, e uma análise de projetos blockchain possíveis de utilizar. O
processo de negócio concebido é relativo ao aluguer de automóveis, e de que forma, com
recurso à blockchain várias empresas do mesmo ramo industrial conseguem partilhar
informação relativa aos seus ativos.
A solução final desenvolvida resulta numa prova de conceito totalmente funcional utilizando o
projeto Hyperledger Fabric, com um conjunto de smart contracts que atendem ao processo
de negócio.
Os resultados obtidos são considerados positivos, dada a elevada componente de investigação
inerente à temática e pormenorização da implementação da solução desenvolvida, que
representa um sólido suporte para soluções futuras. Cumpriu-se com os objetivos propostos.
Blockchain technology has shown a growing trend of applicability in various industry sectors. Its operation is based on a decentralized information system and excels in considerable performance and high security. This project, carried out in an academic context, aims to promote knowledge about the blockchain technology, and how it, together with smart contracts, can be used in industrial systems with multiple participants, preserving mutualistic relationships. For this purpose, a careful investigation of the technology's concepts, real industrial cases of its use, and an analysis of blockchain projects that could be used were carried out. The designed business process is related to car rental, and how, using blockchain, several companies in the same industrial sector can share information regarding their assets. The final solution developed results in a fully functional proof of concept using the Hyperledger Fabric project, with a set of smart contracts that serve the business process. The results obtained are considered positive, given the high level of research inherent to the theme and the detailed implementation of the developed solution, which represents a solid support for future solutions. The proposed objectives were accomplished.
