1. 私链环境搭建

1.1. 安装环境

Ubuntu 16或18 CentOS 7 MacOS golang版本1.14及以上，同时需要C编译器

1.2. 获取源代码

$ git clone https://github.com/DNAProject/Zion

1.3. 编译源代码

  • 编译geth
$ make geth
  • 全部编译
$ make all

编译后可在build/bin目录中生成二进制可执行文件

1.4. 环境搭建

环境搭建以单机搭建4节点私链网络为例。

1.4.1. 生成节点初始配置信息

利用 genesisTool 生成节点初始化配置文件

./geth genesisTool generate --basePath <outputPath> --nodeCount <nodeCount> --nodePass <nodePass>

以下是生成4节点配置文件示例：

./geth genesisTool generate --basePath ./genesisOutput --nodeCount 4 --nodePass 1234

生成三份文件：
