部署CITA和区块链浏览器以及智能合约

docker pull cita/cita-run:ubuntu-18.04-20180813
或者直接进入容器里面
docker exec -it 29f /bin/bash
然后查看Solidity 版本
solc --version

---

下载 CITA 源码
从 Github 仓库下载 CITA 的源代码，然后切换到 CITA 的源代码目录
git clone https://github.com/citahub/cita.git
cd cita
git submodule init
git submodule update
./env.sh
然后新建文件
touch SimpleStorage.sol
内容:
pragma solidity ^0.4.24;

contract SimpleStorage {
uint storedData;
event Init(address, uint);
event Set(address, uint);
event Stored(uint);

constructor() public {
    storedData = 100;
    emit Init(msg.sender, 100);
}

function set(uint x) public {
    emit Stored(x);
    storedData = x;
    emit Set(msg.sender, x);
}

function get() public constant returns (uint) {
    return storedData;
}

}
然后
获得合约的相关信息
使用 solc 命令得到一些部署和调用需要的信息：

字节码

部署合约需要字节码信息。

$ solc SimpleStorage.sol --bin
输出：

======= SimpleStorage.sol:SimpleStorage =======
Binary:

函数签名

调用合约需要函数签名信息。

$ solc SimpleStorage.sol --hashes
输出：

======= SimpleStorage.sol:SimpleStorage =======
Function signatures:
6d4ce63c: get()
60fe47b1: set(uint256)
合约
由测试用户进行操作：

$ cita-cli rpc sendRawTransaction
