Storj has the ability to act as a distributed file system using Tardigrade, and allows you to contribute storage and bandwidth in return for receiving Storj coins to your wallet.
I happen to have about 300TB of extra RAID 6 capacity here and 2x1Gb fiber w/redundant failover and load-balancing. I am playing around with putting it to use with Storj as a side-project, and it got me thinking as to whether or not something similar already exists on top of Tezos?
