+\nsection{Shielding Rule}
+
+Previously Hush inherited the rule about shielding coinbase before sending to a
+transparent address. Now that Hush is based on Komodo, this rule no longer
+exists, which means mining pools can send newly mined coinbase funds directly to
+pooled miners.
+
+The rule was well-intentioned, but it did not result in real privacy
+improvements, since 95\% of all ZEC is still in transparent addresses, and
+people move amounts "throught" zaddrs (instead of keeping funds in them) in such
+a way as to make transactions easy to link.
+
+Hush will take the stance of educating users to the risks of transparent addresses,
+constantly, and make shielded operations the default in all GUI wallets.
+
+Additionally, since shielding is so fast now, and various service providers are
+now supporting Sapling shielded addresses, we encourage users to hold funds in
+Sapling zaddrs by default and only use transparent addresses when necessary,
+such as exchanges that only support transparent addresses.
