Storj is a decentralized cloud storage platform that leverages a distributed network of node operators to store encrypted, sharded file data across thousands of nodes worldwide. The platform offers an S3-compatible gateway, making it a practical drop-in replacement for centralized cloud storage providers like AWS S3. Its encryption-by-default architecture and geographic distribution provide strong security and redundancy guarantees.

As a file storage solution, Storj excels with competitive pricing, proven uptime, and a mature product that has undergone multiple iterations since its 2017 launch. The open-source codebase and established network of storage node operators lend credibility to the project's long-term viability.

However, Storj's classification under DeFi Infrastructure is a stretch — it primarily serves as decentralized storage rather than providing core DeFi primitives like lending, liquidity, or oracle services. While dApps could theoretically use Storj for off-chain data storage, its integration into DeFi ecosystems remains limited.

The STORJ ERC-20 token facilitates payments between storage users and node operators, though adoption metrics and token velocity warrant monitoring. Competition from Filecoin and Arweave remains a key risk factor.
