@ -340,6 +340,14 @@ The Human-Readable Parts of Unified Viewing Keys are defined as:
* *prefix* || “``view``” for Unified Full Viewing Keys on Mainnet;
* *prefix* || “``viewtest``” for Unified Full Viewing Keys on Testnet.
While support for Revision 1 UAs/UVKs is still being rolled out across
the Zcash ecosystem, a Producer can maximize interoperability by
generating a Revision 0 UA/UVK in cases where the conditions on its
use are met (i.e. there are no MUST-understand Metadata Items, and at
least one shielded item). At some point when Revision 1 UA/UVKs are
widely supported, this will be unnecessary and it will be sufficient
to always produce Revision 1 UA/UVKs.
