How does a private coin work with blockchain tech? If you can't know who the sender and receiver are how can you verify transactions?

There's an optionable Payment ID you can attach (also encrypted), so receiver can confirm that the payment received was for a particular purpose.

Let's say payment id is user id + product id, so receiver could easily confirm that transaction was from a particular user for a particular product.
