Zen as cryptocurrency (forked from Zcash) and main product of the platform has all abilities as Zcash. https://www.horizen.global/zen/ You can choose between transparency and privacy using regular (T) or private (Z) addresses.
So can a person who is delegating to nodes, choose to generate private Z address coins instead of the regular T coins and vice versa?
Does the Arizen wallet allow for the generation of both coins?
Check Horizen main wallet application https://www.horizen.global/spherebyhorizen/ I like to say that future belongs to this application because it will be lot of updates and integrations within this wallet.
