ipfs

星际文件系统IPFS（Inter-Planetary File System）是一个面向全球的、点对点的分布式版本文件系统，目标是为了补充（甚至是取代）目前统治互联网的超文本传输协议（HTTP），将所有具有相同文件系统的计算设备连接在一起。原理用基于内容的地址替代基于域名的地址，也就是用户寻找的不是某个地址而是储存在某个地方的内容，不需要验证发送者的身份，而只需要验证内容的哈希，通过这样可以让网页的速度更快、更安全、更健壮、更持久。

IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas from previous systems such as Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single BitTorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built-in. You can also mount the world at /ipfs.

IPFS 云成为一个新的、重要的网络子系统，如果构建得当，可以完善或者替换 HTTP，或者更多。

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
