I suggest you to first read the CATA whitepaper before we keep discussing this project. CATA is not just offering decentralized storage, it has so much other stuff to offer. You better read the paper and come up with some logical answer.
You can find more about CATA on the documentation section provided on there website along with whitepaper. That's the only reading material available till now and i think its sufficient to understand the concept that is provided by CATA. The concept is innovative yet not many focused on it.
