The IPFS is a global, peer-to-peer, distributed version of the file system. The goal is to supplement (or even replace) the HTTP that currently rules the Internet. The principle is to use content-based addresses instead of domain-based addresses, that is, users are not looking for an address but content stored in a certain place. There is no need to verify the identity of the sender, but only the hash of the content. Filecoin is an incentive layer on top of IPFS, and a decentralized storage market that is built on IPFS through the token incentive model.
