The main purpose of ZCash is to allow people to send and receive funds quickly, cheaply and most importantly — privately. In fact, the ZCash team hope that one day it will become a global payments system used by people all around the world.
Pros
the ZCash blockchain can process transactions much quicker than Bitcoin and it is also more scalable. Scalability is important as it means that a blockchain can process lots of transactions at once
Cons
There is a slight issue, though. For the first four years, ZCash developers will get 20% of all the transaction fees generated. They say that this will help fund the project, however, some people think this is unfair
