1. Hyperledger Fabric

區塊鏈技術發展至今，形成了公有鏈、聯盟鏈和邦鏈三種種主流技術平台。

公有鏈：面向大眾，用戶可以匿名參與，非常方便，賬本數據也公開，加上強大的智能合約，因此公有鏈極大地促進了區塊鏈概念和技術的普及，比如比特幣、Ethereum平台等。

聯盟鏈：考慮到商業應用對安全、隱私、監管、審計、性能的需求，提高準入門檻，增加了安全、隱私、可監管審計等商業特性，是區塊鏈技術在商業領域的應用探索。

邦鏈：暫時資料比較少。

概念

通道（ Channel ）：通道是構建在 Hyperledger Fabric 區塊鏈網絡上的私有區塊鏈，實現了數據的隔離和保密。通道中的 Chaincode 和交易只有加入該通道的節點（ Peer ）可見。同一個節點可以加入多個通道，併為每個通道內容維護一個賬本。每一個通道即為一條邏輯上的區塊鏈。可以按照業務來劃分通道，也可以按照行政職能和隱私策略來劃分通道。

節點（ Peer ）：維護賬本的網絡節點，通常區塊鏈網絡架構中存在多種角色，如 endorser 和 committer 。

排序服務或共識服務（ Order Services ）：提供排序服務或共識服務的網絡節點，完成交易的排序和區塊打包等工作，支持可插拔的共識組件，當前生產環境下使用 Kafka 進行交易排序。

分散式賬本（ Distribute Ledger ）：由網絡中若干去中心化節點共同維護的數據賬本。

組織（ Org ）：聯盟鏈中按照訪問和使用賬本的網絡節點，一個聯盟（或者一個區塊鏈網絡）有多個組織（成員），一個組織內可以有多個節點（ Peer ），每個節點參與賬本和世界狀態維護。

智能合約（ Smart Contract ）：根據特定條件自動執行的合約程序。智能合約是區塊鏈的重要特徵，是用戶與區塊鏈進行交互，利用區塊鏈實現業務邏輯的重要途徑。

鏈碼（ Chaincode ）：鏈碼是 Hyperledger Fabric 對智能合約的一種實現方式，是運行于 Hyperledger Fabric 網絡之上一段應用程式碼，也是用戶與 Hyperledger Fabric 交互的唯一途徑。

鏈（ Chain ）：一個鏈即是一個由若干區塊通過特定指向連結、摘要算法或加密算法錨定組成的數據集合。

2. 安裝 Hyperledger Fabric

2.1. 依賴工具

			
yum -y install epel-release
yum install -y git
yum install -y golang

2.2. 安裝Docker

			
curl -s https://raw.githubusercontent.com/oscm/shell/master/virtualization/docker/docker.centos7.ce.sh	 | bash
curl -s https://raw.githubusercontent.com/oscm/shell/master/virtualization/docker/registry-mirror.sh	 | bash
or 
curl -fsSL https://get.docker.com/ | sh	

創建2個docker網絡,如下：
docker network create fabric_noops
docker network create fabric_pbft

安裝 docker-compose

			
curl -s https://raw.githubusercontent.com/oscm/shell/master/virtualization/docker/docker-compose.sh	 | bash

2.3. 安裝 Node.js 環境

			
yum install -y nodejs
npm install

2.4. 安裝 hyperledger 1.0.4

運行後 hyperledger 相關鏡像被安裝到 Docker 中

			
cd /usr/local/src
curl -s https://raw.githubusercontent.com/hyperledger/fabric/release/scripts/bootstrap-1.0.4.sh | bash

由於上面腳本會安裝所有節點，速度較慢，作者建議你參考下一章節，手工安裝所需最低配置節點。

2.5. 手工安裝 hyperledger v 1.0.5 開發環境

對於開發環境，最小化的環境，包括 1 個 peer 節點、1 個 Orderer 節點、1 個 CA 節點。

準備一個伺服器或者虛擬機，安裝 CentOS 操作系統。

如果你是在已有的Docker上安裝，建議你刪除所有容器後在安裝。以免出現衝突等情況。

			
docker stop $(docker ps -q) && docker rm $(docker ps -aq)

2.5.1. 登錄 docker

				
[root@localhost ~]# docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: netkiller
Password: 
Login Succeeded

2.5.2. Docker 安裝

				
docker pull hyperledger/fabric-baseimage:latest \
  && docker pull hyperledger/fabric-membersrvc:latest \
  && docker pull hyperledger/fabric-peer:latest \
  && docker pull hyperledger/fabric-orderer:latest \
  && docker pull hyperledger/fabric-ca:latest \
  && docker pull hyperledger/blockchain-explorer:latest

安裝會出現下面問題

				
[root@localhost ~]# docker search fabric-peer | grep hyperledger/fabric-peer
hyperledger/fabric-peer            Fabric Peer docker image for Hyperledger Pro…   69

[root@localhost ~]# docker pull hyperledger/fabric-peer:latest
Error response from daemon: manifest for hyperledger/fabric-peer:latest not found

可以 search 到的鏡像 pull 不了，原因是 fabric-peer:latest，latest 不存在，你需要指定版本號。

				
docker pull hyperledger/fabric-ca:x86_64-1.0.5 \
&& docker pull hyperledger/fabric-peer:x86_64-1.0.5 \
&& docker pull hyperledger/fabric-orderer:x86_64-1.0.5 \
&& docker pull hyperledger/fabric-couchdb:x86_64-1.0.5 \
&& docker pull hyperledger/fabric-tools:x86_64-1.0.5

docker tag hyperledger/fabric-ca:x86_64-1.0.5 hyperledger/fabric-ca \
&& docker tag hyperledger/fabric-peer:x86_64-1.0.5 hyperledger/fabric-peer \
&& docker tag hyperledger/fabric-orderer:x86_64-1.0.5 hyperledger/fabric-orderer \
&& docker tag hyperledger/fabric-couchdb:x86_64-1.0.5 hyperledger/fabric-couchdb \
&& docker tag hyperledger/fabric-tools:x86_64-1.0.5 hyperledger/fabric-tools

查看鏡像

				
[root@localhost src]# docker images
REPOSITORY                      TAG                 IMAGE ID            CREATED             SIZE

hyperledger/fabric-peer         latest              c2ab022f0bdb        2 months ago        154MB
hyperledger/fabric-peer         x86_64-1.0.5        c2ab022f0bdb        2 months ago        154MB
hyperledger/fabric-membersrvc   latest              b3654d32e4f9        15 months ago       1.42GB

2.5.3. 編譯安裝

				
git config --global core.autocrlf false				
$ git clone https://github.com/hyperledger/fabric.git 
$ make docker 
$ git clone https://github.com/hyperledger/fabric-ca.git		
$ make docker 

cd fabric/devenv
vagrant box add hyperledger/fabric-baseimage centos7.box
vagrant up

yum -y install epel-release
yum -y install git
yum -y install golang
yum -y install python-pip	
pip install --upgrade backports.ssl_match_hostname
pip install docker-compose

docker-compose -version

2.6. 啟動 docker 虛擬機

體驗 Hyperledger Fabric 在 https://github.com/hyperledger/fabric/tree/release/examples 下面有一些例子供用戶學習。這裡我選擇的是 fabric-samples

這裡我們最小化啟動，需要四個節點，分別是 ca, peer, order, couchdb。

創建檔案 docker-compose.yml

				
[root@localhost ~]# mkdir -p docker

2.7. 管理 hyperledger

2.7.1. CouchDB 管理界面

					
[root@localhost fabcar]# curl http://localhost:5984
{"couchdb":"Welcome","version":"2.0.0","vendor":{"name":"The Apache Software Foundation"}}

http://localhost:5984/_utils/

2.8. 部署 chaincode

2.8.1. channel 管理

Hyperledger Fabric Channel 可以理解為 vlan （交換機術語）用來實現區塊隔離。

				
[root@localhost docker]# docker-compose exec peer0.org1.example.com bash
root@dcb09db1cbc8:/go/src/github.com/hyperledger/fabric#

上面 ERROR 可能是因為 hyperledger v1.0.5 版本的緣故。此時的 fabric-samples 僅僅支持 v1.0.0。

4. e2e_cli

運行這個命令請慎重，這裡是為了不被先前的實驗產生的容易所影響，清理 Docker 虛擬機，

		
[root@localhost ~]# docker rmi -f $(docker images -q)

克隆源碼，因為我們需要 example 目錄中的檔案，所以將 https://github.com/hyperledger/fabric.git 源碼克隆到本地。

		
[root@localhost ~]# go get github.com/hyperledger/fabric
		
[root@localhost ~]# git clone --depth=1 https://github.com/hyperledger/fabric.git
[root@localhost ~]# cd fabric
[root@localhost fabric]# make release
[root@localhost ~]# cd ~/fabric/examples/e2e_cli/
[root@localhost e2e_cli]#

5. Hyperledger Composer

Build Blockchain applications and business networks your way

https://hyperledger.github.io/composer/

6. 創世區塊

創建創世區塊需要兩個配置檔案，一個是 crypto-config.yaml 檔案，另一個是 configtx.yaml 檔案

6.1. crypto-config.yaml

crypto-config.yaml 證書配置檔案

			
OrdererOrgs:
  - Name: Orderer
    Domain: example.com
    Specs:
      - Hostname: orderer
PeerOrgs:
  - Name: Org1
    Domain: org1.example.com
    Template:
      Count: 1
    Users:
      Count: 1

Name：定義名稱

Domain與Hostname：組合成為節點的名稱，也是生成後的檔案夾的名稱。

Template: 模板數量

Users：用來指定添加進節點的預設用戶數

Count：用來指定每個org下邊所擁有的節點數。

如果有多個Peer節點參考下面配置。

			
[root@localhost netkiller]# vim crypto-config.yaml

OrdererOrgs:
  - Name: Orderer
    Domain: example.com
    Specs:
      - Hostname: orderer
PeerOrgs:
  - Name: Org1
    Domain: org1.example.com
    Template:
      Count: 2
    Users:
      Count: 1
  - Name: Org2
    Domain: org2.example.com
    Template:
      Count: 2
    Users:
      Count: 1

6.2. configtx.yaml

7. Chaincode

7.1. 在宿主主機上編譯合約

編譯所以來的庫檔案

			
yum install libtool-ltdl-devel
go get github.com/hyperledger/fabric

編譯合約檔案

			
[root@localhost ~]# cd ~/netkiller/chaincode/chaincode_example02/
[root@localhost chaincode_example02]#

[root@localhost chaincode_example02]# go build chaincode_example02.go 

[root@localhost chaincode_example02]# ls
chaincode_example02  chaincode_example02.go  chaincode_example02_test.go

8. hyperledger/fabric-ca

go 安裝方式

		
go get github.com/hyperledger/fabric-ca

9. Restful 介面

9.1. 註冊

			
curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d '
