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. We believe in open and resilient networks that belong to the users. These are the building blocks to make that possible.
You can find a wide array of real-world projects built with IPFS in the ecosystem directory and awesome-ipfs list.
