Hierarchical Deterministic Key Generation for Sapling
|
|
|
|
-----------------------------------------------------
|
|
|
|
All Sapling addresses will use hierarchical deterministic key generation
|
|
|
|
according to ZIP 32 (keypath m/32'/133'/k' on mainnet). Transparent and
|
|
|
|
Sprout addresses will still use traditional key generation.
|
|
|
|
|
|
|
|
Backups of HD wallets, regardless of when they have been created, can
|
|
|
|
therefore be used to re-generate all possible Sapling private keys, even the
|
|
|
|
ones which haven't already been generated during the time of the backup.
|
|
|
|
Regular backups are still necessary, however, in order to ensure that
|
|
|
|
transparent and Sprout addresses are not lost.
