A corrente de blocos (blockchain) \u00e9 uma tecnologia disruptiva que deve revolucionar o nosso modo de viver, trabalhar e negociar. A corrente de blocos \u00e9 considerada a tecnologia que vai revolucionar a Internet, provendo uma camada de confian\u00e7a distribu\u00edda. Assim como a Internet permite hoje a transfer\u00eancia de arquivos, a tecnologia de corrente de blocos permitir\u00e1 a Internet de Valores, na qual \u00e9 poss\u00edvel a transfer\u00eancia sem intermedi\u00e1rios de ativos, tais como dinheiro, a\u00e7\u00f5es, propriedade intelectual, votos, etc. \u00a0 A corrente de blocos em sua ess\u00eancia \u00e9 uma simples estrutura de dados imut\u00e1vel que armazena registros de transa\u00e7\u00f5es e que \u00e9 replicada em todos os participantes da rede. Os algoritmos de consenso que determinam a forma como se tomam as decis\u00f5es coletivas e como s\u00e3o obtidas as finaliza\u00e7\u00f5es das tarefas s\u00e3o a parte fundamental e mais complexa de corrente de blocos. Existem dezenas de algoritmos de consenso com diferentes caracter\u00edsticas, dentre elas gasto energ\u00e9tico, desempenho, toler\u00e2ncia a falha de equipamentos, robustez a ataques de conluio, escalabilidade, etc. Assim, este cap\u00edtulo foca em algoritmos de consenso para ajudar o projetista de corrente de blocos a escolher o consenso apropriado para suas aplica\u00e7\u00f5es.<\/p>\n
Diversos algoritmos de consenso s\u00e3o apresentados especificando suas caracter\u00edsticas, suas vantagens, suas desvantagens e finalidades.\u00a0 Outro foco deste minicurso \u00e9 uma parte pr\u00e1tica que mostra a constru\u00e7\u00e3o de uma aplica\u00e7\u00e3o de corrente de blocos usando a plataforma Hypeledger Fabric, que \u00e9 uma plataforma de corrente de blocos privada, modular e de c\u00f3digo aberto, al\u00e9m de ser a mais utilizada pelas empresas. A aplica\u00e7\u00e3o prov\u00ea garantia de an\u00e1lise forense em um ambiente de fun\u00e7\u00f5es virtualizadas de rede.<\/p>\n
