以太坊Geth及mac安装

• geth 全称go-ethereum，是以太坊的 go 语言命令行客户端，目前比较流行的一种。
• The Go implementation is called Geth. Geth has been audited for security and will be the future basis for the enduser-facing Mist Browser, so if you have experience with web development and are interested in building frontends for dapps, you should experiment with Geth.
• 通过Geth，可以实现以太坊的各种功能,如账户的新建编辑删除，开启挖矿，ether币的转移，智能合约的部署和执行等
