The timeout window for block downloads scales proportionally to the target
spacing for the chain, as set in chainparams.cpp. This causes issues on regtest
because the spacing is set to 1 second, allowing insufficient time for very
large blocks to sync when requested in batch, preventing success of the pruning
qa test.
We fix this by introducing a minimum multiplier (in seconds) that will be used
instead of the target block spacing whenever the latter is lower. With a value
of 10 seconds, pruning tests pass.
Removes "1.14" that was embedded in the logo image on the overview
screen and replaces it with a dynamically generated version in the
lower left corner.
Changes the dust policy to require transactions to add the dust
limit itself rather than the relay or wallet fee to the fees paid
when creating dust outputs.
This both disincentivizes dust outputs the same as before when dust
and minumum fee were equal and greatly simplifies the rule, as it
no longer requires 2 variables to calculate dust, but just one:
"If an output is under x, add x to the fee."
MIN_CHANGE influences the minimum change output size but was only
hardcoded and wallet users were not able to override this in any
way. This change retains the logic for the calculation as a
hardcoded constant but instead uses the user-configurable params
-discardthreshold and -mintxfee as a basis. The rationale for
having the minimum change equal to the discard threshold plus 2x
the minimum fee has not changed.
MIN_FINAL_CHANGE was a hardcoded limit that was impossible to be
changed by users. This causes problems when the dust limit is
changing because then a user would need a new release to be able
to have lower change outputs.
This commit replaces the entire notion of MIN_FINAL_CHANGE to just
follow the discard threshold, which can be set by the user using
-discardthreshold.
Sets the high tx fee to be higher than the default values
implemented by the wallet. The highest value from the QT coin
control slider is 5.21 DOGE.
Therefore, a 10 DOGE/kB high tx fee should suffice for now.
As of writing, 97% of the relay network (for me: 2251 of 2328
peers) enforces a 1 DOGE hard dust limit making attempts to send
smaller outputs extremely unlikely to make it through to miners.
This setting is a temporary measure until a significant portion of
the network accepts lower dust thresholds. The threshold can be
changed by wallet users using the -discardthreshold parameter.
DustRelayFee (-dustrelayfee) was used sporadically throughout the
code, even though it had been disabled for dust determination, but
has now completely been removed from all dust and fee related
queries. Therefore, it can be removed from the code.
Moves the warning from DUST_RELAY_TX_FEE to DEFAULT_HARD_DUST_LIMIT
as it is very relevant for the latter, but never was relevant for
the former as it was disabled for us.
Creates a wallet-specific, configurable dust limit that enables
gradual implementation of the dust limit. Each transaction created
with the wallet will adhere to this threshold rather than the dust
limits used for relay, so that the wallet stays usable while the
network changes (lowers) its dust limits.
This change only implements the parameter but does not change its
default value.
Creates a new parameter, -harddustlimit, that is used for testing
standard transactions. The default is set at 1/10th of the (soft)
dust limit, to be the same as the default minimum relay fee and
leave space for future improvements.
The existing dust limit (-dustlimit) is now enforcing the economic
disincentive under which each output under the limit must add
additional fee to be accepted to the mempool. Before this commit,
-dustlimit enforced both the hard and the soft limits, which
effectively removed the soft limit altogether.
Prepares for having more than one dust limit configured, yet
allowing the same function to return whether or not an output is
dust.
Implements the check with nDustLimit (-dustlimit) for relay related
queries, and - for lack of alternatives - uses the same parameter
for CWallet::GetRequiredFee until a wallet-specific dust limit is
introduced
Some tests expect MIN_CHANGE to be less than COIN, which will not
be the case as long as the network enforces a 1 DOGE hard dust
limit.
wallet_tests.cpp: Multiply all inputs by 10 for tests that aren't
relative to MIN_CHANGE.
fundrawtransaction.py: make sure there are no outputs smaller than
1 DOGE.
importprunedfunds.py: Multiply all outputs by 100
Updates MIN_CHANGE to always allow for a subsequent bump from the
change output using RBF or CPFP of at least 2x the recommended
minumum fee, on top of the dust limit, because the previous value
did not allow enough change for performing a CPFP bump, and only
allowed for a single bumfee call, which would spend the entire
change output rather than allowing for optimization.
Sets WALLET_INCREMENTAL_RELAY_FEE to 1/10th of the default
recommended minimum fee, to encourage using RBF over CPFP and
saving the additional blockspace required for child transactions
spending parent transactions.
The previous value was based off a 1 DOGE recommended fee and did
not make sense with the current minimum fee recommendation.
The value of DEFAULT_INCREMENTAL_RELAY_FEE has never been tuned for
Dogecoin since porting from Bitcoin Core 0.14. Even though the dual
meaning of this parameter is suboptimal, it can still be tuned.
This commit sets the value to 1/10th of DEFAULT_MIN_RELAY_TX_FEE
from validation.h, which causes:
1. Mempool limiting to be performed in steps of 0.0001 DOGE/kb
instead of 0.00001 DOGE/kb
2. RBF to be accepted by the mempool if the new fee is at least
0.0001 DOGE/kb higher than the previous fee known to the
mempool
3. RBF to be cheaper than CPFP by a factor 10 (as the latter would
require a fee of more than 0.001 DOGE/kb on a subsequent bumping
transaction), to encourage mempool replacement over prioritizing
through additional transactions that need to be mined.
4. Mempool limiting to be 10x faster to reset to zero than before,
because for bitcoin, fee increments equaled their minimum fee,
but for us this was 1/100th.
mempool_tests.cpp has been reworked a bit to reflect the reality
of having a lower increment than the minimum fee, as even though
this already was the case, this was not tested correctly due to the
static values in the unit test.
Refresh the most active translation files. As we're not set up with the same tooling as Bitcoin, we get slightly different results compared to the files they generate, so I've picked only specific files to update to reduce churn. If we have translation volunteers for other languages we can update those languages at the time.

Introduces RECOMMENDED_MIN_TX_FEE as a constant that explicitly
sets a single value and then implements this value for each fee
related constant throughout the code, instead of using values
relative to COIN. This helps because it makes the relation of
other defaults to the fee recommendation clear and makes
choices made by developers in wallet configuration easier to
read and understand.
This commit only changes existing values to be expressed relative
to the recommended fee and does not change actual values.
* Change from a block target number to using speed labels which pick predefined fee values.
* Remove smart fee labels from send coins control dialog.
* Rename slider position configuration for Qt, as smart fee slider settings are not compatible with preset fee settings.
