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)

I’m assuming the zupass team is planning to do more with this. 

I really like whatever zupass is. It’s more interesting than the wallet abstraction. A collection of tickets and cards.

I was kidding at devconnect that everyone from Berlin had a deck of cards to hand out instead of a business card so I’d need to make one myself before visiting Berlin.

I guess I could make generic claims like “I have  either frog A or frog B” without revealing which

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
