configtx.yaml是Hyperledger Fabric區(qū)塊鏈網(wǎng)絡(luò)運(yùn)維工具configtxgen用于生成通道創(chuàng)世塊或通道交易的配置文件，configtx.yaml的內(nèi)容直接決定了所生成的創(chuàng)世區(qū)塊的內(nèi)容。

Capabilities / 通道能力配置

Capabilities段用來定義fabric網(wǎng)絡(luò)的能力。這是版本v1.0.0引入的一個(gè)新的配置段，當(dāng)與版本v1.0.x的對(duì)等節(jié)點(diǎn)與排序節(jié)點(diǎn)混合組網(wǎng)時(shí)不可使用。

Capabilities段定義了fabric程序要加入網(wǎng)絡(luò)所必須支持的特性。例如，如果添加了一個(gè)新的MSP類型，那么更新的程序可能會(huì)根據(jù)該類型識(shí)別并驗(yàn)證簽名，但是老版本的程序就沒有辦法驗(yàn)證這些交易。這可能導(dǎo)致不同版本的fabric程序中維護(hù)的世界狀態(tài)不一致。

因此，通過定義通道的能力，就明確了不滿足該能力要求的fabric程序，將無法處理交易，除非升級(jí)到新的版本。對(duì)于v1.0.x的程序而言，如果在Capabilities段定義了任何能力，即使聲明不需要支持這些能力，都會(huì)導(dǎo)致其有意崩潰。

Capabilities:
    # Global配置同時(shí)應(yīng)用于排序節(jié)點(diǎn)和對(duì)等節(jié)點(diǎn)，并且必須被兩種節(jié)點(diǎn)同時(shí)支持。
    # 將該配置項(xiàng)設(shè)置為ture表明要求節(jié)點(diǎn)具備該能力
    Global: &ChannelCapabilities
        V1_3: true

    # Orderer配置僅應(yīng)用于排序節(jié)點(diǎn)，不需考慮對(duì)等節(jié)點(diǎn)的升級(jí)。將該配置項(xiàng)
    # 設(shè)置為true表明要求排序節(jié)點(diǎn)具備該能力
    Orderer: &OrdererCapabilities
        V1_1: true

    # Application配置僅應(yīng)用于對(duì)等網(wǎng)絡(luò)，不需考慮排序節(jié)點(diǎn)的升級(jí)。將該配置項(xiàng)
    # 設(shè)置為true表明要求對(duì)等節(jié)點(diǎn)具備該能力
    Application: &ApplicationCapabilities
        V1_3: true

Organizations / 組織機(jī)構(gòu)配置

Organizations配置段用來定義組織機(jī)構(gòu)實(shí)體，以便在后續(xù)配置中引用。例如，下面的配置文件中，定義了三個(gè)機(jī)構(gòu)，可以分別使用ExampleCom、Org1ExampleCom和Org2ExampleCom引用其配置：

Profiles / 配置入口

Profiles配置段用來定義用于configtxgen工具的配置入口。包含委員會(huì)（consortium）的配置入口可以用來生成排序節(jié)點(diǎn)的創(chuàng)世區(qū)塊。如果在排序節(jié)點(diǎn)的創(chuàng)世區(qū)塊中正確定義了consortium的成員，那么可以僅使用機(jī)構(gòu)成員名稱和委員會(huì)的名稱來生成通道創(chuàng)建請(qǐng)求。
