 # Zcash Protocol Family Tree
+
+Here we represent, for the first time that we know, a family tree of Zcash
+Protocol coins which use Zcash source code. We note that Bitcoin Gold (BTG)
+is not listed because they use the PoW algorithm from Zcash (Equihash) but
+do not use any of the privacy-related code.

+
+The category of "Komodo Asset Chains" contains dozens of blockchains which
+have shielded transaction support. Hush Smart Chains are similar but focus
+purely on Proof-of-Work (not Proof-of-Stake) use cases and are focused on
+privacy-by-default use cases. This is sometimes calles "z2z" because sending
+to zaddrs is required and sending from a zaddr to a transparent address is
+not allowed.
