Capabilities / 通道能力配置

Capabilities段用來定義fabric網絡的能力。這是版本v1.0.0引入的一個新的配置段，當與版本v1.0.x的對等節點與排序節點混合組網時不可以使用。app

Capabilities段定義了fabric程序要加入網絡所必須支持的特性。例如，若是添加了一個新的MSP類型，那麼更新的程序可能會根據該類型識別並驗證簽名，可是老版本的程序就沒有辦法驗證這些交易。這可能致使不一樣版本的fabric程序中維護的世界狀態不一致。運維

所以，經過定義通道的能力，就明確了不知足該能力要求的fabric程序，將沒法處理交易，除非升級到新的版本。對於v1.0.x的程序而言，若是在Capabilities段定義了任何能力，即便聲明不須要支持這些能力，都會致使其有意崩潰。函數

Capabilities:
    # Global配置同時應用於排序節點和對等節點，而且必須被兩種節點同時支持。
    # 將該配置項設置爲ture代表要求節點具有該能力
    Global: &ChannelCapabilities
        V1_3: true

    # Orderer配置僅應用於排序節點，不需考慮對等節點的升級。將該配置項
    # 設置爲true代表要求排序節點具有該能力
    Orderer: &OrdererCapabilities
        V1_1: true

    # Application配置僅應用於對等網絡，不需考慮排序節點的升級。將該配置項
    # 設置爲true代表要求對等節點具有該能力
    Application: &ApplicationCapabilities
        V1_3: true

Organizations / 組織機構配置

Organizations配置段用來定義組織機構實體，以便在後續配置中引用。例如，下面的配置文件中，定義了三個機構，能夠分別使用ExampleCom、Org1ExampleCom和Org2ExampleCom引用其配置：工具
