Storj, pronounced as "storage," is an open-source cloud storage platform that leverages a decentralized network of nodes to host user data. It seeks to provide a unique approach to data storage by utilizing the unused hard drive space of participants in the network. Unlike traditional cloud storage solutions that store data in large data centers, Storj operates on a network of independent computers globally. This decentralized network connects users who need cloud storage space with those who have hard drive space to spare. The platform compensates these space providers, known as nodes, with Storj tokens. This system strives to protect user data against potential threats and eliminates the risk of storing data in a few isolated data storage units.

Storj operates by using its Tardigrade software installed on node computers to create and safeguard user data. Each file is encrypted before being dispersed to the network of independent hosts. Each node only receives a random fragment of a whole file, with decryption keys split among each node and the host. This is designed to resist hacking attempts. Node operators are compensated for hosting data and confirming the safety and retention of the hosted files in a process known as mining. The Storj token is used for this purpose. Individuals or organizations who want to store their data on the network provide the Storj tokens paid to nodes. This system strives to protect user data against hacks and other malicious attacks.

Storj seeks to provide an alternative to traditional cloud storage solutions. It could be used by anyone with extra terabytes of space and a strong, consistent internet connection. This makes it a potential solution for individuals, businesses, and organizations looking for a decentralized approach to data storage. Moreover, Storj could be a solution for those looking to contribute to a distributed digital economy, as it compensates participants for providing storage space.

Storj was first introduced as a concept in a white paper published in December 2014. It was founded by Shawn Wilkinson and John Quinn, who published the first white paper in late 2014. The platform was launched in late 2018. Wilkinson, a software developer based in Atlanta, saw how blockchain technology could be leveraged to build a decentralized cloud storage network. The current version of Storj, V3, was launched in the middle of 2019. The platform raised funds in its early years.
