AFAIK we have already filecoin who provide similar things. Can you tell a newbie like me how you differ with already existing projects like filecoin that are providing storage facility.
Filecoin is a file system. It is more like a cold storage facility, focusing on the storage function itself. CATA has not only built a decentralized file system protocol, but also a flexible metadata query engine on the upper layer that can support SQL. And we will continue to expand the upper layer storage facility to provide a more complete decentralized big data system.
