InterPlanetary File System (IPFS) is a protocol and network designed to create a content-addressable, peer-to-peer method of storing and sharing hypermedia in a distributed file system.[3] 
Similar to a torrent, IPFS allows users to not only receive but host content. As opposed to a centrally located server IPFS is built around a decentralized system of user-operators who hold a 
portion of the overall data, creating a resilient system of file storage and sharing.

IPFS is a peer-to-peer distributed file system that seeks to connect all computing devices with the same system of files. IPFS could be seen as a single BitTorrent swarm, exchanging objects 
within one Git repository. In other words, IPFS provides a high-throughput,[failed verification] content-addressed block storage model, with content-addressed hyperlinks.[4]

The filesystem can be accessed in a variety of ways, including via FUSE[failed verification] and over HTTP.[4]

IPFS was launched in an alpha version in February 2015, and by October of the same year was described as "quickly spreading by word of mouth."[1]

In 2019 the project has been criticized for being "still not usable for websites" in spite of attracting huge investments and creating an "overextended, under-documented, and unfinished 
constellation of projects".[5]
