Hello @ARMY971 ,
Welcome to the forum!
We do not use blockchain to store data. And it will not work for anyone, see
Our service is to provide the decentralized encrypted cloud storage, compatible with s3.
We do not offer blockchains and related to blockchains services.
We use blockchain only for our utility token, which is used to pay to SNO for their service and as a payment method when you use the Storj DCS as a customer.
Our DApps - most of the customers’ application in meaning, that they uses the Decentralized cloud storage, see Storj Docs for documentation.
The other DApp - is our storagenode software: Storage Node Getting Started - Storj Docs
To complete your research you can use our Storj Whitepaper V3, our Storj Blog and Storj DCS Resources
