What are in ZCash the equivalent of PaymentID and ViewKey avail in Monero?


#1

I didn't find much info about it.

PaymentID: it's just and ID to proof that a certain transaction is actually done by the sender: It is optional and visible to everybody on the blockchain.

ViewKey: it is a 2nd private key that can only see the transactions without the ability of to spend funds.

Thanks

Zcash isn't based on Ring signatures but ZK-Snarks (Zero-Knowledge Succinct Non-interactive Argument of Knowledge).

It has transparent addresses (t-addresses) and secure addresses (z-addresses).
