它利用了configtx.yaml文件，个中包括网络的界说，因此我们将在burakcan-network目次下建设以下文件。

界说crypto-config.yaml文件后，我们在burakcan-network目次下执行以下呼吁通道。

在开始之前，你先要设置好Hyperledger Fabric的插件和设置好情况变量。详细可以参考上一遍文章。 Channel: &ChannelCapabilities

然后，我们将继承安装平台特定的二进制文件时已经安装的configtxgen东西，该东西也将安排在fabric-samples/bin文件夹下。它提供了生成这些重要设置工件的要领。

我们在fabric-samples文件夹下建设一个名为burakcan-network的文件夹。在我们的网络中，有3个节点，包罗2个组织，别离是BurakCan1和Burakcan2，以及1个orderer，因此我们需要生成所有证书和密钥来证明节点是否真的是本身。我们将利用cryptogen东西提供用于为我们的网络实体生成暗码质料，，而且在安装特定于平台的二进制文件时已经安装了它。它放在fabric-samples / bin文件夹下。它利用了包括网络拓扑的crypto-config.yaml文件，并答允我们为组织以及属于这些组织的组件生成一组证书和密钥。 - *Burakcan2

这就是我们在burakcan网络目次下建设以下文件的原因。我们界说了一个Orderer组织（OrdererOrg）和2个对等组织（Burakcan1和Burakcan2）。组织中的每个计数值都指定该组织中的peers数。 Capabilities:

在本文中我们将建设一个自界说网络，并利用Hyperledger Fabric v2.1陈设示例链代码。之后，我们将查询chaincode并由我们将建设的2个对等点与网络举办交互。
