Storj is a decentralized, peer-to-peer cloud storage network.

Storj was first described in a white paper published in December, 2014. It was later described in an updated white paper published in December, 2016. Storj launched in late 2018. It aims to connect users looking to purchase storage space with users who have hard drive space to sell. Users are incentivized to use Storj tokens (STORJ) for these purchases, however, the network also supports other payment methods, such as bitcoin, ether, and even fiat currencies. 

By providing users with a P2P cloud storage network that implements end-to-end encryption, the Storj network eliminates a user's need to rely on a trusted third party. This solves for most traditional data breaches, failures, and outages, while at the same time increasing a user’s security, privacy, and data control. Storj currently operates as a decentralized alternative to the centralized cloud storage solutions provided by Amazon, Dropbox, IBM, Google Drive, and more.
