Fabric快速入门讲解 fabric是什么意思

下面我们来学习Fabric的网络 。在这里我贴出了英语原文，英语不好的小伙伴可直接看中文（翻译的不贴切的处所，请多多指教） 。本系列教程上中下三部分 。在本节我们先来学习下“什么是Fabric网络”，“fabric网络在公司运用中的例子”，“网络的组件”和“如何创立一个Fabric网络” 。
什么是Fabric网络？Fabric网络是具有权限管理的区块链网络，技巧架构上为花费者和管理员供给散布式的账本服务 。在大部分情形下，在一个联盟中，最初配置时是须要有网络管理权限的 。并且，联盟中的成员达成一致后，策略是可以转变的 。
A Fabric permissioned blockchain network is a technical infrastructure that provides ledger services to application consumers and administrators. In most cases, multiple organizationscome together as a consortium to form the network and their permissions are determined by a set of policies that are agreed to by the consortium when the network is originally configured. Moreover, network policies can change over time subject to the agreement of the organizations in the consortium.
公司运用区块链网络的一个例子有RA,RB,RC和RD四个组织决议应用Fabric网络进行共同投资 。组织RA将会安排3个Peer节点和2个客户端运用 。组织RB将会安排4个Peer节点和一个客户端运用 。组织RC将会安排3个Peer节点和两个客户端运用 。组织RD将会安排4个排序节点 。RA和RB之间可以形成一个联盟，并且树立一个通道在他们之间 。同理，RC和RD也可以这么做 。每个运用通道又可以配置自己的策略 。
The organizations RA, RB, RC and RD have decided to jointly invest in a Fabric blockchain network. Organization RA will contribute 3 peers, and 2 client applications of RA will consume the services of the blockchain network. Organization RB will contribute 4 peers and has 1 client application. Organization RC contributes 3 peers and has 2 client applications. Organization RD contributes 4 orderers. Organization RA and RB have decided to form a consortium and exploit a separate application channel between the two of them. Organization RB and RC have decided to form another consortium and also exploit a separate application channel between the two of them. Each application channel has its own policy.
网络的组件一个Fabric网络由以下部分组成：

  • 账本（每个通道都有一个，由区块链和状况数据库组成）
  • 智能合约（在Fabric网络中也称为链码）
  • Peer节点
  • 排序服务
  • 通道
