The new RPCs aren't functional, only have argument parsing and sample
outputs, guarded by experimental -orchardwallet flag.
These changes used the tickets linked from
https://github.com/zcash/zcash/issues/5056 as a guide.
zip339_phrase_to_seed will return `false` if the string it is being
used to convert to a seed is not valid UTF-8, but this result was
previously unchecked.
Fixes#5399
This type is backed by the `zcash_address` implementaion of
unified full viewing keys. It is intended for serialization
and parsing of UFVKs, and provides conversion functions that
allow for construction to and from ZcashdUnifiedFullViewingKey
values.
Adds SaplingDiversifiableFullViewingKey as a superclass of
SaplingExtendedFullViewingKey, and reduces the Sapling component
of UnifiedFullViewingKey to the new intermediate type. This
permits deserialization from the data that will be present
in the serialized form of the Sapling component of a UFVK.
This test-only change allows python (rpc) tests to specify, for example,
that NU5 should be activated at height X, without having to specify all
the previous network upgrades. Previous upgrades can (and must) still be
specified if they activate at different block heights (than, in this
example, NU5). This makes tests easier to write (and read), especially
as the number of network upgrades increases over time.
Note that this change only affects zcashd behavior in regtest mode. For
the other network modes (testnet and mainnet), the activation heights
are hard-coded in chainparams.cpp.
This commit does not include functional changes; it merely
breaks up content previously included in `zcash/address/zip32.h`
into smaller and more focused components.
Remove IncrementalSinsemillaTree; this will be replaced by
a more full-featured OrchardWallet type which embeds the
incremental merkle tree used in wallet operations.
Adds HD seed derivation from ZIP-339 mnemonic phrases.
This replaces random generation of transparent spending keys with BIP-44-compatible derivation from a mnemonic seed phrase, and replaces the random HD seed previously used for Sapling HD key derivation
with the same mnemonic seed. After this change, all new transparent and Sapling addresses
will be derived from a new randomly generated mnemonic seed, which is produced in such a way that
it is guaranteed to produce valid unified spending keys at account 0 for all address types.
Closes#5176.
Closes#2673.
