IPFS(InterPlanetary File System)是一个点对点的分布式超媒体分发协议,它整合了过去几年最好的分布式系统思路,为所有人提供全球统一的可寻址空间,包括Git、自证明文件系统SFS、BitTorrent和DHT,同时也被认为是最有可能取代HTTP的新一代互联网协议。
IPFS用基于内容的寻址替代传统的基于域名的寻址,用户不需要关心服务器的位置,不用考虑文件存储的名字和路径。我们将一个文件放到IPFS节点中,将会得到基于其内容计算出的唯一加密哈希值。哈希值直接反映文件的内容,哪怕只修改1比特,哈希值也会完全不同。当IPFS被请求一个文件哈希时,它会使用一个分布式哈希表找到文件所在的节点,取回文件并验证文件数据。
IPFS是通用目的的基础架构,基本没有存储上的限制。大文件会被切分成小的分块,下载的时候可以从多个服务器同时获取。IPFS的网络是不固定的、细粒度的、分布式的网络,可以很好的适应内容分发网络的要求。这样的设计可以很好的共享各类数据,包括图像、视频流、分布式数据库、整个操作系统、模块链、8英寸软盘的备份,还有静态网站。

Use 'ipfs <command> --help' to learn more about each command.
ipfs uses a repository in the local file system. By default, the repo is
located at ~/.ipfs. To change the repo location, set the $IPFS_PATH
environment variable:
export IPFS_PATH=/path/to/ipfsrepo
EXIT STATUS
The CLI will exit with one of the following values:
0 Successful execution.
1 Failed executions.
如ipfs id
,可以查看你的通信ID信息
使用ipfs swarm peers
可以查看附近也在使用IPFS网络节点伙伴,可以发现不是你一个人在战斗
