Rationale for address derivation
''''''''''''''''''''''''''''''''
The design of address derivation is designed to maintain unlinkability
between addresses derived from the same UIVK, to the extent possible.
(This is only partially achieved if the UA contains a Transparent P2PKH
Address, since the on-chain transaction graph can potentially be used to
link transparent addresses.)
Note that it may be difficult to retain this property for Metadata Items,
and this should be taken into account in the design of such Items.
Requirements for both Unified Addresses and Unified Viewing Keys
