16 Prática sobre Hyperledger: Introdução ao Fabric
Introdução ao Fabric
Resumo
A proposta desta prática é explorarmos o uso do Hyperledger Fabric.
16.1 Introdução
O Hyperledger Fabric é um projeto do Hyperledger que é uma plataforma para o desenvolvimento de blockchains permissionados, com suporte à modularidade de componentes e versatilidade para uma série de contextos da indústria.
O Fabric oferece uma pilha de desenvolvimento em cinco camadas:
Pré-requisitos de software: Lista de dependências de softwares necessários para dar suporte à instalação e execução de projetos com
Fabric.Fabrice Exemplos: Fornecem os executáveis para rodar uma rede Fabric com exemplos de código.APIsde Contratos: para o desenvolvimento de contratos inteligentes que serão executados em uma Rede Fabric.Application APIs: para o desenvolvimento de aplicações _ blockchain_.A aplicação: a aplicação desenvolvida utilizará os kits de desenvolvimento (SDKs) para chamar contratos inteligentes em execução em uma Rede Fabric.
Ele pode ser instalado via uma script que permite instalar binários, exemplos e imagens docker.
16.2 Instalando os binários do Fabric, Exemplos e Imagens Docker
Crie um diretório para ser o diretório de trabalho, os desenvolvedores Go usam o padrão $HOME/go/src/github.com/<your_github_userid>. Esta é uma recomendação da comunidade Golang para projetos que utilizem Go.
No meu caso foi a seguinte sequência de comandos no terminal:
$ mkdir -p $HOME/go/src/github.com/rogerioag
$ cd $HOME/go/src/github.com/rogerioagPara fazer o download do script de instalação:
[rogerioag]$ curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.shAo executa o script com a opção -h ele mostrará o conjunto de opções aceitas pelo script de instalação.
[rogerioag]$ ./install-fabric.sh -h
Usage: ./install-fabric.sh [-f|--fabric-version <arg>] [-c|--ca-version <arg>] <comp-1> [<comp-2>] ... [<comp-n>] ...
<comp>: Component to install one or more of d[ocker]|b[inary]|s[amples]. If none specified, all will be installed
-f, --fabric-version: FabricVersion (default: '2.5.14')
-c, --ca-version: Fabric CA Version (default: '1.5.15')O script de instalação permite a escolha de componentes que serão baixados e adicionados à plataforma de desenvolvimento. Permite indicar se queremos utilizar o docker ou o podmanpara fazer download das images de conteiner, se queremos os binários do Fabric e os exemplos de utilização.
Para baixar as imagens e conteineres docker e clonar o repositório de exemplos, execute o comando:
$ ./install-fabric.sh docker samples binary
or
$ ./install-fabric.sh d s bForcendo os argumentos ao script as opções escolhidas serão baixadas.
[rogerioag]$ sudo ./install-fabric.sh docker samples binary

[rag@backporting rogerioag]$ Por pdrão o script de instalação irá buscar os componentes da última versão. Caso queiramos baixar versões específicas podemos fornecê-las com os parâmetros --fabric-version e -ca-version ou opções curtas -f e -c.
Por exemplo, para baixamos os binários na versão v2.5.14, precisaremos executar o comando:
$ ./install-fabric.sh --fabric-version 2.5.14 binaryAssim teremos instalados em nosso sistema a versão desejada dos binários, exemplos ou imagens docker.
Para desenvolvedores que queiram definir um ambiente de desenvolvimento para contribuir com o Fabric, instruções pode ser vistas no link Setting up the contributor development environment.
Ajuda e questões podem ser enviadas para o canal fabric-questions no Hyperledger Discord Chat ou no StackOverflow.

[test-network]$ 16.4 Teste de deploy de contrato
Contratos Inteligentes são implantados na rede Fabric em pacotes denominados chaincode. Um chaincode é instalado nos pares de uma organização e então implantado para um canal, onde poderá ser utilizado para validar transações e interagir com o livro-razão da blockchain.
Antes que um chaincode possa ser implantado em um canal, os membros do canal precisam concordar com uma definição de chaincode que estabeleça a governança do chaincode. Quando o número necessário de organizações concordar, a definição do chaincode poderá ser confirmada no canal e o chaincode estará pronto para uso.
Depois de utilizar o script network.sh para criar um canal, você pode iniciar um chaincode no canal usando os comandos:
[test-network]$ sudo ./network.sh down
