什么是量子链
量子链是一个基于比特币核心和集成Ethereum的智能合约的新的区块链。他实现了一种可扩展的设计，能添加更多的虚拟机，允许账户的虚拟机在UTXO的区块链上执行。
安装
需要有OS X的命令行工具
xcode-select --install需要环境安装Homebrew.
安装依赖
brew install cmake automake berkeley-db4 libtool boost --c++11 --without-single --without-static miniupnpc openssl pkg-config protobuf qt5 libevent imagemagick --with-librsvg

下面进行编译
make
经过漫长的等待,编译成功。
Making all in doc/man
make[1]: Nothing to be done for `all'.
make[1]: Nothing to be done for `all-am'.启动
执行src/qtumd或者src/qtum-cli
启动UI界面的话，执行src/qt/qtum-qt
注意目前的是主干网络。
领取测试网络的币
访问 http://qtum.me/#!/ ,领取测试币的发放。
在钱包界面，找到receive，在界面中，点击请求付款，就会得到一个地址，将地址复制到网页中，就能收到测试代币。
…
一直没收到，失败~
切换到测试网络
拉取测试网络的代码 git checkout testnet-2
然后再次执行
./autogen.sh
./configure
make注意的是，切换网络后，需要删除之前用的数据文件，所在的位置是~/Library/Application Support/Qtum
到此，量子链的正式环境和测试环境部署完成。
