具体参考树状区块链启动和创建节点。

！不明晰点！复现手册中，并未给出创世块genesis.json的配置信息。 解决方法：使用传统区块链的初始化和启动中给出的创世块配置信息genesis.json替代。目前尚未发现副作用。

00 项目建立

使用mkdir指令新建一个名为TreeBlockchain的文件夹。

为什么使用 mkdir指令呢？这是因为，若像在Windows中一样，在图形界面中右键新建文件夹，那么这个文件夹的权限将会比较高，使用命令行对其中的文件进行操作时，必须加上很多sudo才行。而使用mkdir创建的文件夹就不会有这个问题。

在其中，放入上文所述的genesis.json。其内容如下：

{
  "config": {
    "chainId": 666,
    "homesteadBlock": 0,
    "eip150Block": 0,
    "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "eip155Block": 0,
    "eip158Block": 0,
    "byzantiumBlock": 0,
    "constantinopleBlock": 0,
    "petersburgBlock": 0,
    "istanbulBlock": 0,
    "ethash": {}
  },
  "nonce": "0x0",
  "timestamp": "0x5ddf8f3e",
  "extraData": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "gasLimit": "0x47b760",
  "difficulty": "0x00002",
  "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "coinbase": "0x0000000000000000000000000000000000000000",
  "alloc": { },
  "number": "0x0",
  "gasUsed": "0x0",
  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000"
}

同时，将周畅前辈提供的geth1二进制文件（位于仓库根目录）放入系统的/usr/bin/目录下。

此时，可以用以下两条指令，确认系统中确实有两个版本的geth：

geth version
# Geth
# Version: 1.10.26-stable
# --snip--
geth1 version
# Geth
# Version: 1.9.12-stable
# --snip--

！不明晰点！直接使用geth，得到了形如... flag provided but not defined的错误信息。

解决方法：使用geth1替代，错误信息消失。

01 初始化 & 启动

以上准备工作完成后，初始化区块链：

geth1 --identity "MyEth" --rpc --rpcaddr 127.0.0.1  --rpcport "8545" --rpccorsdomain "*" --datadir gethdata --port "30303" --nodiscover --rpcapi "eth,net,personal,web3" --networkid 91036 init genesis.json

初始化完毕后，再启动区块链：

geth1 --identity "MyEth" --rpcaddr 127.0.0.1 --rpc --rpcport "8545" --rpccorsdomain "*" --datadir gethdata --port "30303" --nodiscover --rpcapi "eth,net,personal,web3" --networkid 91036 --allow-insecure-unlock --dev.period 1 console

原复现手册中有提及“如果同时开两个区块链节点的话...”。在这个实验中，我们仅使用一个节点即可完成实验。如果想启动多个节点，请见下一个实验的报告文档。

02 建立账户

进入JavaScript控制台。在其中创建账户：

personal.newAccount("123456")

获得返回的账户名称，为0x32d655db60309c87b95387e3b843253d43ba7731。根据复现手册指示，将genesis.json中的alloc字段修改，修改后的genesis.json如下：

{
  "config": {
    "chainId": 666,
    "homesteadBlock": 0,
    "eip150Block": 0,
    "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "eip155Block": 0,
    "eip158Block": 0,
    "byzantiumBlock": 0,
    "constantinopleBlock": 0,
    "petersburgBlock": 0,
    "istanbulBlock": 0,
    "ethash": {}
  },
  "alloc": {
    "0x32d655db60309c87b95387e3b843253d43ba7731": {
      "balance":"50000000000000000000000000000000000000000",
      "position":"test0123456789",
      "txtime":1
    }
  },
  "nonce": "0x0",
  "timestamp": "0x5ddf8f3e",
  "extraData": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "gasLimit": "0x47b760",
  "difficulty": "0x00002",
  "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "coinbase": "0x0000000000000000000000000000000000000000",
  "number": "0x0",
  "gasUsed": "0x0",
  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000"
}

随后，在终端中输入exit退出JavaScript控制台，再将目录TreeBlockchain/gethdata/geth删除。

03 重启区块链 & 确认账户信息

使用如下指令，重新初始化并启动区块链：

geth1 --identity "MyEth" --rpc --rpcaddr 127.0.0.1  --rpcport "8545" --rpccorsdomain "*" --datadir gethdata --port "30303" --nodiscover --rpcapi "eth,net,personal,web3" --networkid 91036 init genesis.json

geth1 --identity "MyEth" --rpcaddr 127.0.0.1 --rpc --rpcport "8545" --rpccorsdomain "*" --datadir gethdata --port "30303" --nodiscover --rpcapi "eth,net,personal,web3" --networkid 91036 --allow-insecure-unlock --dev.period 1 console

进入JavaScript控制台。进入后，输入如下指令查看余额：

eth.getBalance(eth.accounts[0])
// 5e+40

输入以下指令解锁账户：

personal.unlockAccount(eth.accounts[0],"123456",15000)
// true

04 部署合约

再输入如下代码，点按一次回车：

//部署合约contract在移动区块链上,将下述代码直接粘贴到控制台
abi = JSON.parse('[{\"constant\":false,\"inputs\":[{\"internalType\":\"string\",\"name\":\"uuid\",\"type\":\"string\"}],\"name\":\"revalue\",\"outputs\":[],\"payable\":false,\"stateMutability\":\"nonpayable\",\"type\":\"function\"},{\"constant\":true,\"inputs\":[{\"internalType\":\"string\",\"name\":\"uuid\",\"type\":\"string\"}],\"name\":\"getQuality\",\"outputs\":[{\"internalType\":\"int256\",\"name\":\"\",\"type\":\"int256\"}],\"payable\":false,\"stateMutability\":\"view\",\"type\":\"function\"},{\"constant\":true,\"inputs\":[{\"internalType\":\"string\",\"name\":\"uuid\",\"type\":\"string\"}],\"name\":\"getSinglePos\",\"outputs\":[{\"internalType\":\"uint256\",\"name\":\"\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"\",\"type\":\"uint256\"}],\"payable\":false,\"stateMutability\":\"view\",\"type\":\"function\"},{\"constant\":false,\"inputs\":[{\"internalType\":\"string\",\"name\":\"uuid\",\"type\":\"string\"},{\"internalType\":\"uint256\",\"name\":\"time\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"_latOri\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"_lonOri\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"_latFix\",\"type\":\"uint256\"},{\"internalType\":\"uint256\",\"name\":\"_lonFix\",\"type\":\"uint256\"}],\"name\":\"setSinglePos\",\"outputs\":[],\"payable\":false,\"stateMutability\":\"nonpayable\",\"type\":\"function\"}]')

这样就将合约上传到了区块链上。然而，必须开始挖矿，才能真正完成部署操作。

05 开始挖矿

最后执行：

miner.start()

控制台提示开始生成DAG。待percentage字段达到99（不知为何到不了100，到99似乎就已经完成了），注意到两个不同于其他的输出：
