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使用。
Capabilities段定義了fabric程序要加入網絡所必須支持的特性。例如,如果添加了一個新的MSP類型,那麽更新的程序可能會根據該類型識別並驗證簽名,但是老版本的程序就沒有辦法驗證這些交易。這可能導致不同版本的fabric程序中維護的世界狀態不一致。
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,除非升級到新的版本。對於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,都會導致其有意崩潰。
Capabilities: # Global配置同時應用於排序節點和對等節點,並且必須被兩種節點同時支持。 # 將該配置項設置為ture表明要求節點具備該能力 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 # 設置為true表明要求排序節點具備該能力 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 # 設置為true表明要求對等節點具備該能力 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,可以分別使用ExampleCom、Org1ExampleCom和Org2ExampleCom引用其配置:
Organizations: - &ExampleCom Name: ExampleCom ID: example.com AdminPrincipal: Role.ADMIN MSPDir: ./ordererOrganizations/example.com/msp Policies: Readers: Type: Signature Rule: OR(‘example.com.member‘) Writers: Type: Signature Rule: OR(‘example.com.member‘) Admins: Type: Signature Rule: OR(‘example.com.admin‘) Endorsement: Type: Signature Rule: OR(‘example.com.member‘) - &Org1ExampleCom Name: Org1ExampleCom ID: org1.example.com MSPDir: ./peerOrganizations/org1.example.com/msp AdminPrincipal: Role.ADMIN AnchorPeers: - Host: peer0.org1.example.com Port: 7051 Policies: Readers: Type: Signature Rule: OR(‘org1.example.com.member‘) Writers: Type: Signature Rule: OR(‘org1.example.com.member‘) Admins: Type: Signature Rule: OR(‘org1.example.com.admin‘) Endorsement: Type: Signature Rule: OR(‘org1.example.com.member‘) - &Org2ExampleCom Name: Org2ExampleCom ID: org2.example.com MSPDir: ./peerOrganizations/org2.example.com/msp AdminPrincipal: Role.ADMIN AnchorPeers: - Host: peer0.org2.example.com Port: 7051 Policies: Readers: Type: Signature Rule: OR(‘org2.example.com.member‘) Writers: Type: Signature Rule: OR(‘org2.example.com.member‘) Admins: Type: Signature Rule: OR(‘org2.example.com.admin‘) Endorsement: Type: Signature Rule: OR(‘org2.example.com.member‘)
Orderer / 排序節點配置
Orderer配置段用來定義要編碼寫入創世區塊或通道交易的排序節點參數。
Orderer: &OrdererDefaults
# 排序節點類型用來指定要啟用的排序節點實現,不同的實現對應不同的共識算法。
# 目前可用的類型為:solo和kafka

Application / 應用配置
Application配置段用來定義要寫入創世區塊或配置交易的應用參數。
Application: &ApplicationDefaults
ACLs: &ACLsDefault
# ACLs配置段為系統中各種資源提供默認的策略。
# 這裏所說的“資源”,可以是系統鏈碼的函數,例如qscc系統鏈碼的GetBlockByNumber方法
# 也可以是其他資源,例如誰可以接收區塊事件。
# 這個配置段不是用來定義資源或API,而僅僅是定義資源的訪問控制策略
#
# 用戶可以在通道定義中重寫這些默認策略

Profiles配置段用來定義用於configtxgen工具的配置入口。包含委員會(consortium)的配置入口可以用來生成排序節點的創世區塊。如果在排序節點的創世區塊中正確定義了consortium的成員,那麽可以僅使用機構成員名稱和委員會的名稱來生成通道創建請求。
