Deterministically generating zPIV using a single seed (similar in concept to a private key for all zPIV generated by a wallet) will allow users to fully backup their zPIV, which includes any zPIV that will be generated in the future by that seed. The zPIV seed is part of the wallet.dat and will be backed up anytime a user saves a copy of their wallet.dat file. Alternatively users will be able to manually export their zPIV seed using the debug console, as well as manually import the seed.
Why is this important? Many users have had confusion about how exactly zPIV backups work. Some have deleted the wallet.dat files that contain the zPIV, giving them no ability to restore their deleted zPIV. Now users will be able to have piece of mind knowing that they will be able to easily recover zPIV.
NOTE: Command "getzpivseed" will be available on our future wallet releases shortly
