Incoming viewing keys
Support for incoming viewing keys, as described in the Zcash protocol spec, has been added to the wallet.
Use the z_exportviewingkey RPC method to obtain the incoming viewing key for a
z-address in a node's wallet. For Sprout z-addresses, these always begin with
"ZiVK" (or "ZiVt" for testnet z-addresses). Use z_importviewingkey to import
these into another node.
A node that possesses an incoming viewing key for a z-address can view all past
transactions received by that address, as well as all future transactions sent
to it, by using z_listreceivedbyaddress. They cannot spend any funds from the
address. This is similar to the behaviour of "watch-only" t-addresses.
z_gettotalbalance now has an additional boolean parameter for including the
balance of "watch-only" addresses (both transparent and shielded), which is set
to false by default. z_getbalance has also been updated to work with
watch-only addresses.
- Caution: for z-addresses, these balances will not be accurate if any funds have been sent from the address. This is because incoming viewing keys cannot detect spends, and so the "balance" is just the sum of all received notes, including ones that have been spent. Some future use-cases for incoming viewing keys will include synchronization data to keep their balances accurate (e.g. #2542).
