Storj (STJ) hopes to provide decentralised cloud storage to its community. Storj works on the premise that each user is entitled to the same amount of space on the network as they make available to the community. Users can also receive payment for renting their extra disk space. Files are split up into smaller components and dispersed across an array of devices, with users maintaining control of their keys, which grants them access to their files, at all times. As a result, this decentralised cloud storage model creates additional security for users relative to centralized cloud storage providers.
Please note, on Ethfinex, Storj ticker is the three letter STJ and not STORJ.
