Could someone who understands zk proofs better than me explain the advantages of doing the frogcrypto frog cards as PCD blobs instead of say NFTs? Is the PCD unique to the specific frog I have or is it associated with the frog species? Can 2 cards of the same frog be distinguished (I have multiples of some)

1) PCDs are default private; NFTs are default public 2) PCDs are default non-transferable; NFTs are default transferable 3) PCDs are default free to issue and interact with; NFTs require wallets + gas + blockchain interaction by default 4) PCDs can be made easy to make ZKPs about; NFTs are default hard to ZKP

I say “default” here because there exist schemes to make each of these attributes possible/easier for both types of cryptographically-anchored data. But the defaults define a lot of what will happen in practice
