笔者使用的是mac系统，因此介绍mac下golang的环境搭建。
1、安装Golang的SDK
google官网被墙下载地址如下: http://www.golangtc.com/download ，下载最新的安装包，之后双击安装即可。
安装完成之后，打开终端，输入go、或者go version(查看安装版本)出现如下信息即表示安装成功：
LCore:~ lcore$ go version
go version go1.4.1 darwin/amd64
LCore:~ lcore$
2、配置环境变量
安装完sdk之后接下来便是配置环境变量了，打开终端输入cd ~ 进入用户主目录,之后输入ls －all命令查看是否存在.bash_profile
文件，存在既使用vim .bash_profile打开并编辑该文件。根据自己实际情况，内容如下：
export GOPATH=/Users/lcore/dev/code/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
GOPATH:日常开发的根目录。GOBIN:是GOPATH下的bin目录。
且需要gobin目录加入到path路径下，生成的可执行文件就可以直接运行了。
退出vim,使用source ~/.bash_profile即可完成对golang环境变量的配置了，可以在终端中输入go env查看配置后的效果:
LCore:~ lcore$ go env
GOARCH=”amd64″
GOBIN=”/Users/lcore/dev/code/go/bin”
GOCHAR=”6″
GOEXE=””
GOHOSTARCH=”amd64″
GOHOSTOS=”darwin”
GOOS=”darwin”
GOPATH=”/Users/lcore/dev/code/go”
GORACE=””
GOROOT=”/usr/local/go”
GOTOOLDIR=”/usr/local/go/pkg/tool/darwin_amd64″
CC=”clang”
GOGCCFLAGS=”-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common”
CXX=”clang++”
CGO_ENABLED=”1″
3、开发工具配置(sublime text)
这里笔者选用的是sublime text安装gosublime插件进行开发（golang语法高亮提示），安装方式这里就不多提了。
4、Hello GO
配置好开发环境之后,简单的进行一下go语言的开发。在你的gopath下的src目录下，新建一个文件夹(以项目名称命名)，然后在sublime中打开该文件夹,新建main.go文件即可以进行编码了。
package main
import (
“fmt”
)
func main() {
fmt.Println(“hello go”);
}
代码编写完成之后,使用command＋b打开sublime text终端，使用go build xx(项目名称)对其进行编译,编译通过后将会显示hello go信息。
Xrp defi use cases. XRP has been gaining popularity in the world of decentralized finance (DeFi) due to its unique use cases and capabilities. DeFi refers to a financial system that operates without the need for traditional intermediaries such as banks or financial institutions. Instead, DeFi relies on blockchain technology to enable peer-to-peer transactions and smart contracts. One of the main use https://mysticfinance.org cases of XRP in DeFi is as a liquidity provider. XRP can be used as collateral to provide liquidity on decentralized exchanges, allowing users to trade various digital assets without the need for a centralized intermediary. This helps to reduce trading fees and increase the efficiency of transactions. Another use case of XRP in DeFi is as a means of payment. XRP can be used to facilitate cross-border payments in a fast and cost-effective manner. By using XRP, users can send money to anyone, anywhere in the world, in a matter of seconds. This is particularly useful for individuals and businesses that need to make international payments on a regular basis. XRP can also be used as a stablecoin in DeFi applications. Stablecoins are digital assets that are pegged to a stable asset, such as the US dollar, to reduce price volatility. By using XRP as a stablecoin, users can hold their assets in a stable form while still benefiting from the speed and efficiency of the XRP network. Furthermore, XRP can be used in decentralized lending and borrowing platforms. Users can leverage their XRP holdings to borrow other digital assets or earn interest by lending out their XRP to others. This helps to create a more efficient and inclusive financial system that is accessible to anyone with an internet connection. In addition, XRP can be used in decentralized insurance platforms. Users can purchase insurance coverage using XRP and smart contracts to protect against various risks, such as hacks, theft, or market fluctuations. This helps to provide a safety net for users in the DeFi space and ensures that their assets are protected. Overall, XRP has a wide range of use cases in the world of decentralized finance. From providing liquidity and enabling fast cross-border payments to serving as a stablecoin and supporting decentralized lending and insurance platforms, XRP is a versatile asset that can help to revolutionize the financial industry. As the DeFi space continues to grow and evolve, XRP is likely to play an increasingly important role in powering decentralized financial applications and services.
