Zcash was issued with a goal to introduce privacy in blockchain transactions. It hides transaction details and ensures the privacy of its users by leveraging the zk-SNARKS protocol (based on zero-knowledge proof).
Unlike bitcoin which takes 10 minutes to generate a block, ZCash can do it in 2.5 minutes.

Zcash: all you need to know"
Do you think Zcash is undervalued?
I will constantly say that the technology of the monero is an order of magnitude higher than the Zcash. Prospects have each coin to a lesser or greater extent, but it is better to invest in stability.
