+The '''InterPlanetary File System''' ('''IPFS''') is a [[Communications protocol|protocol]], [[hypermedia]] and [[file sharing]] [[peer-to-peer]] network for storing and sharing data in a [[distributed file system]].

+== Design ==
+{{expand section |date=June 2020}}
+IPFS allows users to host and receive content in a manner similar to [[BitTorrent]]. As opposed to a centrally located server, IPFS is built around a decentralized system<ref>{{Cite journal |last=Krishnan |first=Armin |date=2020 |title=Blockchain Empowers Social Resistance and Terrorism Through Decentralized Autonomous Organizations |journal=[[Journal of Strategic Security]] |volume=13 |issue=1 |pages=41–58 |doi=10.5038/1944-0472.13.1.1743 |issn=1944-0464 |jstor=26907412 |doi-access=free}}</ref> of user-operators who hold a portion of the overall data, creating a resilient system of file storage and sharing. Any user in the network can serve a file by its content address, and other peers in the network can find and request that content from any node who has it using a [[distributed hash table]] (DHT).
+
+In contrast to BitTorrent, IPFS aims to create a single global network. This means that if two users publish a block of data with the same [[Cryptographic hash function|hash]], the peers downloading the content from "user 1" will also exchange data with the ones downloading it from "user 2".<ref>{{Cite web |title=Content addressing |url=https://docs.ipfs.tech/concepts/content-addressing/ |url-status=live |archive-url=https://web.archive.org/web/20200829083138/https://docs.ipfs.tech/concepts/content-addressing/ |archive-date=2020-08-29 |access-date=2020-08-29 |website=docs.ipfs.tech |language=en}}</ref> IPFS aims to replace protocols used for static webpage delivery by using gateways which are accessible with [[Hypertext Transfer Protocol|HTTP]].<ref>{{Cite web |title=IPFS Gateway |url=https://docs.ipfs.tech/concepts/ipfs-gateway/ |url-status=live |archive-url=https://web.archive.org/web/20200829083134/https://docs.ipfs.tech/concepts/ipfs-gateway/ |archive-date=2020-08-29 |access-date=2020-08-29 |website=docs.ipfs.tech |language=en}}</ref> Users may choose not to install an IPFS client on their device and instead use a public gateway.
