The document discusses the distributed web and how the current web architecture can be improved. It describes how the InterPlanetary File System (IPFS) aims to create a permanent, distributed and more censorship-resistant web using content addressing and distributed networks. Key components that enable this include Multiformats for self-describing data, IPFS for content distribution, IPNS for identity and authentication, IPLD for linked data structures, and libp2p for network transport. Examples are given of how IPFS could be used for applications like video streaming, documents, images, 3D models, games, and websites to create a truly distributed web.
