UMA ANÁLISE DE ALGORITMOS DE CONSENSO PARA BLOCKCHAIN VISANDO À IMPLEMENTAÇÃO DE SISTEMAS DE INFORMAÇÃO DISTRIBUÍDOS TRANSPARENTES
Revista de Sistemas e Computação - RSC · 2019
Transparency in distributed-database information systems is only of real value when integration, sharing, consistency and integrity requirements are all firstly guaranteed. By its turn, the Blockchain technology is considered to be the most promising implementation solution to meet these requirements simultaneously. Within this context, this paper analyzes three important consensus algorithms for the Blockchain technology. This analysis includes a theoretical study and a comparative evaluation as well. The results allow us to better understand the most positive points and vulnerabilities of each analyzed algorithm. Finally, general conclusions and future work conclude this article.
