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.
Remove the nType and nVersion as parameters to all serialization methods
and functions. There is only one place where it's read and has an impact
(in CAddress), and even there it does not impact any of the recursively
invoked serializers.
Instead, the few places that need nType or nVersion are changed to read
it directly from the stream object, through GetType() and GetVersion()
methods which are added to all stream classes.
Return JoinSplit and JoinSplitOutput indexes in z_listreceivedbyaddress
This implements a feature request by @nathan-at-least in https://github.com/zcash/zcash/issues/2932 and I wanted to ask for feedback about the exact form of the data returned before updating tests and docs.
Add Note Locking to z_mergetoaddress
Adds note locking to `z_mergetoaddress` allowing it to be invoked multiple times before previous `z_mergetoaddress` operations have finished.

Ignore -mempooltxinputlimit once Overwinter activates
Overwinter changes the SignatureHash function to solve the quadratic hashing problem, so this option will no longer be needed.
