I have looked at their FAQ but I didn't find the answer to this.
Having looked at their whitepaper, it seems to me that the main feature of ZCash is that you can't trace where the money came from, because of zero-knowledge proofs.
My question is, does ZCash also feature anonymity the other way – not being able to trace who the money was paid TO, after it has been paid?
In other words, someone lost X amount, someone gained X amount, and we can't prove who paid whom. But what about simply finding all the people in that block who either gained or lost X? Zcash says it "does not: ... protect against correlations made with public transaction" but what about internal transaction?
