many improvements for the tools in Go Toolchain, from version to version, especially for gc. For example, noticeable lags caused by garbage collecting is a common criticism for languages with automatic implementation in gc basically eliminated the lag problem. gc supports cross-platform compilation. For example, we can build a Windows executable on a Linux OS, and vice versa. Programs written in go language short warm-up duration (so great deployment experience) Some other compiled languages, such as C/C++/Rust may also have these three advantages (and they may have their respective advantages compared to Go)

编译时间的长短是开发愉悦度的一个 重要因素。 编译时间短是很多程序员喜欢Go的一个原因。 Go程序生成的二进制可执行文件常常拥有以下优点： 内存消耗少 执行速度快 启动快 很多C家族语言，比如C/C++/Rust等，也拥有上述的优点。 但它们缺少Go语言 的几个重要优点： 程序编译时间短 像动态语言一样灵活 内置并发支持 上面所有提到的优点使得Go成为一个出众的编程语言。 对于很多项目来说， Go是一个相当不错的选择。 doc子命令来（在终端中）查看Go代码库包的文档。 强烈推荐让你的Go项目支持Go模块特性来简化依赖管理。对一个支持Go模块 特性的项目： go mod init example.com/myproject命令可以用来在当前目录中生成一个 go.mod文件。 当前目录将被视为一个名为example.com/myproject的模块 （即当前项目）的根目录。 此go.mod文件将被用来记录当前项目需要的 依赖模块和版本信息。 mod tidy命令常用。 从Go官方工具链1.16版本开始，我们可以运行go install example.com/program@latest来安装一个第三方Go程序的最新版本（至GOBIN 目录）。 在Go官方工具链1.16版本之前，对应的命令是go get -u example.com/program（现在已经被废弃而不再推荐被使用了）。 我们可以运行go help aSub

WASM简介 WASM是WebAssembly的缩写，是一种运行在浏览器上的字节码，用于解决js 在浏览器上的性能不足的问题。 WASM的指令跟机器码很相似，因此很多高 级语言如C，C++，Go，rust等都可以编译成WASM字节码从而可以运行在浏览 器上。 很多性能相关的模块可以通过用C/C++来编写，再编译成WASM来提高 性能，如视频解码器，运行在网页的游戏引擎，React的虚拟Dom渲染算法 /reserved/identity.cc] 实名合约实名的对象是一个具体的ak。 1 2 3 cd ./contractsdk/cpp cp reserved/identity.cc example ./build.sh 编译好的产出为 ./build 文件夹下的identity.wasm文件。 2. 创建合约账户 在XuperChain中所有的合约都是部署在具体的某个账户下的，所以，为了部署 链上还需要部署一个链名解析合约，该合约目前也已开源 链名解析合约 [https://github.com/xuperchain/xuperchain/blob/master/core/contractsdk/cpp/example/naming/src/naming.cc]。 1 2 3 4 5 6 7 8 9 10 11 12 // 注册一个网络，同时包含网络初始meta信息 RegisterChain(name
