IPFS 是分布式文件系统，寻求连接所有计算机设备的相同文件系统。在某些方面，这很类似于原始的 Web 目标，但是 IPFS 最终会更像单个比特流群交换的 git 对象。
IPFS ＝ InterPlanetary File System
IPFS 云成为一个新的，重要的网络子系统，如果构建得当，那么可以完善或者替换 HTTP，或者说可以完善或者替代更多，听起来很疯狂，但是确实很疯狂！
IPFS 结合了 Git，BitTorrent，Kademlia，SFS 和 Web 的优势，提供跟 HTTP web 一样简单的接口。
IPFS 分为 3 个代码库：
github.com/ipfs/ipfs - IPFS 规范
github.com/ipfs/go-ipfs - Go 实现
github.com/protocol/ipfs-webui - Web 工作台
使用：
