bsc parlia geth私有网络部署

如何部署parlia geth私有网络节点

改动关键点

  1. 出块的验证者节点
    • 创世区块的默认验证者 （第一个epoch前出块的账户）
    • 系统合约中的初始化验证者（区块高度每到达一个epoch之后，会查询系统合约 validatorSet contract 获得当前的验证者）
  2. 中继者注册资金
    • 编译relayerHub合约，将初注册资金改为0，编译合约放置在创建文件中
  3. chainID 私有网络id
  4. alloc初始余额分配情况

具体启动节点步骤：

  1. clone 系统合约项目（官方地址：git@github.com:binance-chain/bsc-genesis-contract.git ，下列仓库有做过验证者集合genesis-validator.js 支持docker编译的优化）

    1
    git clone git@github.com:aranoverse/bsc-genesis-contract.git

  2. init_holder.js：该文件初始化创世区块中的账户资产持有情况。

    const web3 = require("web3")
    const init_holders = [
      {
        // private key is 0x9b28f36fbd67381120752d6172ecdcf10e06ab2d9a1367aac00cdcd6ac7855d3, only use in dev
        address: "0x9b28f36fbd67381120752d6172ecdcf10e06ab2d9a1367aac00cdcd6ac7855d3",
        balance: web3.utils.toBN("10000000000000000000000000000000").toString("hex")
      }
    ];
    exports = module.exports = init_holders

  3. validators.js: 初始化验证者 投票权重之类

    // Configure
    let validators = [
        {
            consensusAddr: "0x9fB29AAc15b9A4B7F17c3385939b007540f4d791",
            feeAddr: "0x9fB29AAc15b9A4B7F17c3385939b007540f4d791",
            bscFeeAddr: "0x9fB29AAc15b9A4B7F17c3385939b007540f4d791",
            votingPower: 0x0000000000000064
        }
    ];

  4. 根据需求改造genesis-template.json 或者 生成之后的genesis.json

    1
    2
    #生成genesis.json 以及编译系统合约
    node generate-genesis.js

  5. config配置参考https://geth.ethereum.org/docs调节，或者以下

  1. 利用genesis.json 初始化，然后运行

    # MacOS
    wget  https://github.com/binance-chain/bsc/releases/download/v1.1.5/geth_mac

    # 最少需要两个在线验证者节点 在第3步中更改
    ./geth  --datadir ${data_dir_1}  init genesis.json
    ./geth  --datadir ${data_dir_2}  init genesis.json

    ./geth --config ./config.toml --datadir ${data_dir_1}  --syncmode snap -unlock ${validator_account_1} --password ${passwd_txt_location} --mine --allow-insecure-unlock --cache 8000 

    # e.g. 
    nohup ./geth --config ./config.toml --datadir ./node1  --syncmode snap -unlock ${addr} --password ./password.txt --mine --allow-insecure-unlock --cache 8000 --verbosity 5  --port  30011 --http.port 8545 --ws.port 8546  > ./node1/node.out 2>&1 &
    nohup ./geth --config ./config.toml --datadir ./node2  --syncmode snap -unlock ${addr} --password ./password.txt --mine --allow-insecure-unlock --cache 8000 --verbosity 5  --port  30012 --http.port 8547 --ws.port 8548   > ./node2/node.out 2>&1 &

  2. 添加到同一网络

    • 方式一：手动添加

      3
      4
      5
      6
      #在节点A拿到enode信息
      ./geth attach ${datadir}/geth.ipc
      admin.nodeInfo.enode
      #节点B添加
      ./geth attach ${datadir}/geth.ipc
      admin.addPeer(${enode1})

    • 方式二：启动一个全节点后拿到enode信息，在启动其他节点之前把config.toml中的BootstrapNodes 添加第一个节点的信息
