We need to bump the `zcashd` protocol version because the new rules are
not compatible with existing rules followed by 170015 nodes, but we
_also_ need to ensure we can still bump it again once we set the testnet
reactivation height (changing node network behaviour again). This commit
also enables RPC tests to run (because previously the nodes considered
each other to be too old for NU5 to be active, and were disconnecting).
This includes:
- `orchard =0.1.0-beta.3` which includes the final circuit changes.
- The new NU5 consensus branch ID.
- Updated ZIP 244 test vectors (which use the NU5 consensus branch ID).
- The legacy_random source should only contain Sprout addresses (as
zcashd now only derives transparent addresses from the mnemonic seed).
- Sapling addresses should appear in the mnemonic_seed source, not the
legacy_seed source (as zcashd no longer ever generates keys there).
The RPC test also now has several additional checks:
- `listaddresses` does not return duplicate addresses (an address can
only come from a single source).
- Address sets are now explicitly checked (to ensure that there are no
unexpected addresses under the checked sources).
We now have a full roster of privacy policies. We can graph the
relationships between the policies; arrows point from more-private to
less-private, and each policy is permitted to reveal information covered
by all policies pointing to it (in addition to the extra information it
is permitted to reveal).
FullPrivacy

AllowRevealedAmounts
v v
AllowRevealedRecipients ---- AllowRevealedSenders
v / v
AllowFullyTransparent <- AllowLinkingAccountAddresses

NoPrivacy
The synthetic `LegacyCompat` policy now uses the `AllowFullyTransparent`
policy for backwards compatibility, and the `FullPrivacy` policy if the
sender or recipients involve Unified Addresses.

Closeszcash/zcash#5678.
This replaces the bool argument with a string argument, enabling us to
add additional privacy strategies. We also alter the default to be
backwards-compatible with existing RPC method usage, by only enabling
the strongest checks if a Unified Address is involved.
Closeszcash/zcash#5676.
Prior to this change, calling `join_network` after a network split
only worked in the case that no new non-coinbase transactions were
created during the network partition; in the case that such a
transaction was created, `join_network` would fail when waiting
for mempool synchronization, because zcashd nodes do not.
automatically broadcast their mempool contents on restart.
This change modifies `setup_network` to wait for mempool synchronization
or not on the basis of a newly added do_mempool_sync flag. In the
case of `join_network`, this flag is set to `False`; the default value
is set to `True` to preserve previous functionality elsewhere.
Tests should explicitly use the `resendwallettransactions` RPC method
to ensure that mempool transactions are rebroadcast before attempting
to synchronize the network after a `join_network` call.
We can't actually test rollback via RPC tests until
wallet persistence is implemented. This implements
a rollback scenario that will should pass after wallet
persistence is implemented.
The addition of `OrchardRawAddress` to `RecipientAddress` drives most of
the changes in this commit, which enable `z_sendmany` to send funds to
addresses in the Orchard pool once NU5 activates.
We also add Orchard-specific information to several RPCs in order for
tests to pass:
- `z_listunifiedreceivers`
- `z_getbalanceforaccount`
- `z_getbalanceforviewingkey`
This fixes a potential bug with importing the mnemonic into a third
party transparent wallet. Previously, if a user called `getnewaddress`,
made a bunch of transactions that generated at least 20 change
addresses, and then called `getnewaddress` again, the two external
addresses would be separated by a gap of more than 20. If this mnemonic
were imported into a third party transparent wallet, the wallet would
not detect any funds in the second (or subsequent) transparent addresses
because it would detect 20 unused addresses in a row (via the BIP 44
default gap limit).
Now, we track external and internal keys separately; repeated calls to
`getnewaddress` will return addresses for sequential keys. This has the
added benefit that the sequence of `getnewaddress` outputs will be the
same after restoring from a backup.
We also add a `type` field to the output objects (matching the field in
`z_viewtransaction`), now that the output type can't be distinguished
solely from the address encoding.
The ZTXOSelector type allows selection of previous Zcash
transaction outputs (both transparent outputs and shielded notes)
on the basis of either a (legacy) bare address, or for a
BIP-44 account.
We now use the empty array of pools to indicate that the default pools
should be used when providing a diversifier index parameter, instead of
needing a default sentinel value for the diversifier index parameter
(which was previously suggested as '*' which would have caused issues
for defining a consistent type for that parameter).
This adds an `allowRevealedAmounts` argument to z_sendmany. This
flag must be present to allow an amount-revealing cross-pool transfer
to be constructed.
This replaces the old implementation of asyncrpcoperation_sendmany
with one where all transaction construction is delegated to the
transaction builder. The capabilities of z_sendmany are somewhat
modified in the process:
* z_sendmany now permits sending funds from a Sprout address to
both transparent and Sapling addresses. PRIVACY NOTE: When
user sends a Sprout->Sapling transaction, the amount of the
transaction is publicly revealed.
* z_sendmany no longer supports transactions sending funds into
the Sprout pool, with the exception of change amounts when
sending from a Sprout address.
* When sending transparent coinbase funds to a set of shielded
addresses, the amount sent to recipients must fully consume
the input value and no change is permitted. This is a slightly
weaker constraint than was previously implemented; in the past,
only a single shielded recipient was allowed.
This adds a new `AddrSet` type for use in note retrieval
as a filter, in place of a heterogeneous list of `RawAddress`
values. `RawAddress` will complicate the handling of addresses
within the wallet after the addition of unified addresses,
because it does not contain transparent receiver types, and
if we retain this polymorphism it means a lot of invalid states
are represented in places we don't want them to be. It's better
to figure out what types of addresses we're working with as soon
as possible after parsing, and use monomorphic calls from there
on in.
We added support for the NU5 consensus rules in v4.5.0, which alters the
block header to contain a `hashBlockCommitments` value instead of the
chain history root. However, the output of `getblocktemplate` wasn't
returning this value; once NU5 activated, the `blockcommitmentshash`
field was being set to "null" (all-zeroes).
In v4.6.0 we added full NU5 support to `getblocktemplate`, by adding a
`defaultroots` field that gave default values for `hashBlockCommitments`
and the components required to derive it. However, in doing so we
introduced a regression in the (now-deprecated) legacy fields, where
prior to NU5 activation they contained nonsense.
This commit fixes the output of `getblocktemplate` to have the intended
semantics for all fields:
- The `blockcommitmentshash` and `authdataroot` fields in `defaultroots`
are now omitted from block templates for heights before NU5 activation.
- The legacy fields now always contain the default value to be placed
into the block header (regaining their previous semantics).

This test currently fails with submitblock returning the error
"bad-heartwood-root-in-block".
Added authdigest to GBT coinbasetxn field because we can't obtain this
via getrawtransaction.

This will ensure that miners can use the values returned by
getblocktemplate (in particular, the block commitment hash)
to submit a valid block using the submitblock RPC.
