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 secure 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. It can be particularly useful for those who value data privacy and security, as the platform's encryption and decentralization features strive to protect user data from potential threats. 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.

Storj operates by leveraging a decentralized network of nodes for data storage, providing a different approach to traditional cloud storage. The process begins with the automatic encryption of all files using AES-256-GCM encryption, with the aim of keeping the data in the hands of the user. The encrypted data is then split into multiple pieces, each of which is indistinguishable from any other object's pieces. This fragmentation is intended to support the security and availability of the data. These pieces are then distributed to uncorrelated nodes around the world, with the intention of supporting data security and privacy. Finally, to retrieve the data, only 29 of an object's pieces are needed to reconstitute the data for download. This decentralized approach to data storage aims to offer a unique perspective on performance, security, and cost-effectiveness.

STORJ tokens are an integral part of the Storj ecosystem, serving as a method of interaction and a facilitator of value transfer. They are used to incentivize storage node operators to contribute stable, performant, long-term storage and bandwidth to the network. These operators are acknowledged for their storage and bandwidth contribution with STORJ tokens. STORJ tokens provide users with an efficient method for acquiring storage and bandwidth. While storage and bandwidth values are represented in dollars, users can contribute with STORJ tokens or traditional currencies. STORJ tokens allow Storj Labs to effectively manage the network, acknowledging a large number of operators across various countries. The token also enables programmatic acknowledgements, such as via smart contracts, and micro-acknowledgements. STORJ tokens can serve as a method of interaction in completely decentralized, non-Storj networks, potentially expanding their use within the broader digital asset ecosystem.

Storj strives to provide a decentralized cloud storage solution that presents several features over traditional centralized cloud storage providers. One of the key features is security. Storj's decentralized cloud storage networks are built on Blockchain technology and use an edge-based security model. This means your data is encrypted, erasure coded, distributed, and stored multi-regionally across the globe, providing no single point of failure. This architecture is designed to resist hacking, tampering, and bitrot. Another feature is its design for uptime. Storj's decentralized cloud storage (DCS) networks distribute object storage data across many statistically uncorrelated network nodes, aiming to reduce downtime and the risk of data loss. Storj's DCS networks are designed for resource optimization, leveraging local networks to place nodes closer to end users, which could result in faster file retrieval and reduced bandwidth usage. Storj's DCS networks are designed with privacy considerations, as they aim to make it almost impossible to block websites and online portals, giving developers peace of mind that their information won't be misappropriated, shut down, or stolen.

Storj addresses data redundancy and durability concerns through a distinctive approach that leverages erasure coding and a decentralized network. In an effort to maintain enterprise-grade 99.95% data availability, Storj employs Reed Solomon erasure coding that automatically divides each object file into 80 or more encrypted pieces across 13,500 geographically diverse nodes running on different ISPs and power grids across the globe. The reconstruction of that encrypted file only requires 29 of those 80 pieces. This implies that even if multiple nodes go offline, the data remains intact. And, Storj has an automated audit and repair process that continually checks the status of its storage nodes and stored data, making repairs as necessary. This approach strives to enhance data redundancy, availability, and durability with the intention of minimizing potential points of failure.

The Storj network is designed to accommodate a wide range of data types and applications, including files that are written once and read many times (WORM - Write Once, Read Many data). This makes it a potential fit for applications such as general backup, database backup, private data storage, multimedia storage and streaming, large file transfer, hybrid cloud storage, machine learning, virtual reality and augmented reality, IoT data, and NFT related digital assets. The Storj network seeks to offer low-cost, high-throughput bandwidth, client-side encryption, and a highly distributed network of storage nodes to ensure data security and rapid recovery. The network is designed with the intention of providing efficient storage for large multimedia files and rapid transit for large amounts of data point to point over the internet.

The Storj Share program is an initiative by Storj that enables individuals and commercial operators to share their surplus hard drive space and network bandwidth on the Storj network. Participants, known as storage node operators, may receive STORJ tokens as non-monetary rewards for their contributions. The program seeks to establish a decentralized cloud storage system that leverages decentralization. It's designed to cater to a wide range of storage needs, from individual users with extra disk space to commercial operators with large-scale excess capacity. The Storj Share program incorporates a 'graceful exit' feature, which allows storage node operators to leave the network without causing data loss or repair costs. This program is part of Storj's broader mission to explore new ways of storing and accessing data, utilizing blockchain technology and peer-to-peer networks.

Storj addresses scalability concerns by implementing a peer-to-peer cloud storage network that leverages client-side encryption. This allows users to transfer and share data without relying on a third-party storage provider. As the network grows, Storj aims to maintain data integrity and acknowledges peers maintaining data through a challenge-response verification system coupled with non-financial incentives. To address access and performance concerns, Storj proposes a model that uses a set of independent or federated nodes. This decentralized approach aims to address traditional data failures and outages, with a focus on enhancing security, privacy, and data control. Storj uses a protocol that enables peers on the network to negotiate contracts, transfer data, verify the integrity and availability of remote data, retrieve data, and acknowledge other nodes. Each peer is an autonomous agent, capable of performing these actions without significant human interaction.
