Add change indicator
This adds to the json returned when calling z_listreceivedbyaddress and z_listuspent an additional field entitiled 'change' which will be either true or false depending on whether or not the note was change from another transaction.
libzcash::PaymentAddress has been renamed to libzcash::SproutPaymentAddress,
and a new typedef boost::variant is now libzcash::PaymentAddress. Similarly
for ViewingKey and SpendingKey.
A new class InvalidEncoding is introduced as the default boost::variant
option for each address and key type; it is used during decoding instead
of boost::optional.
All address and key storage functions in the wallet have been modified to
refer specifically to the Sprout types, as they are used very precisely.
In most other cases, the more general type is leveraged as much as possible,
and we convert to the Sprout type when necessary. This will be subsequently
wrapped in, or replaced with, context-specific functions once Sapling
types are implemented.
Key encoding refactor
Includes code cherry-picked from the following upstream PRs:
- bitcoin/bitcoin#11372
- Only the first three commits (the fourth commit depends on #2390)
Part of #3058.
This patch removes the need for the intermediary Base58 type
CZCPaymentAddress, by providing {Encode,Decode}PaymentAddress
functions that directly operate on the conversion between strings
and libzcash::PaymentAddress.
Sapling merkle tree implementation
Closes#3056.
Please also review https://github.com/zcash/librustzcash/pull/8
This PR:
1. Introduces ZCSaplingIncrementalMerkleTree using Pedersen hashes.
2. Adds support for Sapling anchors into consensus rules. (Adds commitments, checks anchors are correct, handles block (dis)connects, etc.)
3. Handles mempool eviction for obsolete anchors.
4. Enforces correctness of block's Sapling root field
5. Changes miner to correctly apply the Sapling root to the block header
6. Handles mempool consistency checks for anchors
From Sapling, the z-address recipients could require either JSDescriptions or
OutputDescriptions. Instead of trying to give an exact number in the help text,
rely on transaction size estimation to guide user behaviour.
Refactor t-address encoding
Includes code cherry-picked from the following upstream PRs:
- bitcoin/bitcoin#11117
- bitcoin/bitcoin#11259
- Only the second commit (first is for QT code)
- bitcoin/bitcoin#11167
- Only the first commit (the rest are not part of the t-address encoding refactor).
Part of #3058. Precursor to #3202.
This patch removes the need for the intermediary Base58 type
CBitcoinAddress, by providing {Encode,Decode,IsValid}Destination
function that directly operate on the conversion between strings
and CTxDestination.
Update note classes to be polymorphic
Closes#3194. Lays foundation for introduction of Sapling notes through refactoring and creation of a class hierarchy for Sprout notes. This PR updates some tests, but otherwise is a no-op.
