IPFS Stands for InterPlanetary File System and is accompanied by a token called FileCoin which is utilized to support a free market for storage of data and extra disk space. Instead of using location-based addressing, IPFS seeks to publish files that are content-addressed. That is--the content itself defines the address. This unique system has several valuable benefits especially when it comes to tracking revisions of information over time.
The Ethereum Blockchain, launched in 2015, offers the ability to run Smart Contract code on the decentralized network of mining computers. Just as these decentralized applications require decentralized storage, they also provide a uniquely flexible framework for managing storage nodes and accountability.
