IPFS
IPFS is a protocol that's designed to create addressable content and P2P methods to store media in a distributed filesystem. In 2014, IPFS adopted the Bitcoin blockchain in order to store data that needs to be immutable.
Files in IPFS are identified by their hashes, and therefore they are cached in a friendly way. IPFS uses a single massive swarm in which anyone can serve a data block to anyone else; block sharing is not limited to the peers of the file, unlike the BitTorrent protocol. IPFS files can be accessed over a variety of protocols, such as HTTP. IPFS has a name service called Inter-Planetary Name System (IPNS) that is compatible with other name services, such as DNS and .onion.
