Filecoin (aka FIL) has many uses due to it being an open source protocol, incentive layer and marketplace. It’s combined with a peer to peer distributed network protocol known as the InterPlanetary File System (IPFS), that is used for storing as well as sharing data. All in all, you get a more secure web with vastly improved efficiency.
Filecoin and Airbnb do similar things. With regards to Airbnb, there are a large number of homes that weren’t being lived in, so they cleverly decided to create a marketplace to rent them out.
Filecoin is a tech version of what Airbnb does. There is so much digital storage globally that’s not being used. Filecoin has a unique way to utilize all that wasted hard drive space.
