Its not about flow nor about NFTs, CATA in nutshell is a combination of interaction protocols for Flow's Cadence contract layer, enabling integration and full traceability of token transactions and data storage, the aim is to give one window channel for NFT publishing, storage, management and distribution.
AFAIK, flow is one of the most popular blockchain for NFTs and that means CATA main target is to capture NFT market. NFT right now is booming and its a good move to capture NFT market. There are many projects already in this sector, CATA needs to work hard.
