IPFS

IPFS is a modular suite of protocols for addressing, routing, and transferring data, designed from the ground up with the principles of content addressing and peer-to-peer networking... The integrity of all data is verified using hash functions, so you can trust that you always get the data you're looking for... Our peer-to-peer content delivery network is built around the innovation of content addressing: store, retrieve, and locate data based on the fingerprint of its actual content rather than its name or location.
