Dash Core version 0.16
Release is now available from:
https://www.dash.org/downloads/#wallets
This is a new major version release, bringing new features, various bugfixes and other improvements.
This release is mandatory for all nodes.
Please report bugs using the issue tracker at github:

Upgrading and downgrading
How to Upgrade
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Dash-Qt (on Mac) or dashd/dash-qt (on Linux). If you upgrade after DIP0003 activation and you were using version < 0.13 you will have to reindex (start with -reindex-chainstate or -reindex) to make sure your wallet has all the new data synced. Upgrading from version 0.13 should not require any additional actions.
When upgrading from a version prior to 0.14.0.3, the first startup of Dash Core will run a migration process which can take a few minutes to finish. After the migration, a downgrade to an older version is only possible with a reindex (or reindex-chainstate).
Downgrade warning
Downgrade to a version < 0.14.0.3
Downgrading to a version smaller than 0.14.0.3 is not supported anymore due to changes in the "evodb" database format. If you need to use an older version, you have to perform a reindex or re-sync the whole chain.
Downgrade of masternodes to < 0.16
Starting with this release, masternodes will verify protocol versions of other masternodes. This will cause PoSe punishment/banning of out of date masternodes, so it is not recommended to downgrade masternodes.
Notable changes
Block Reward Reallocation
This version implements Block Reward Reallocation which was proposed in order to slow the growth rate of Dash’s circulating supply by encouraging the formation of masternodes and was voted in by the network. The resulting allocation will split all non-proposal block rewards 40% toward miners and 60% toward masternodes in the end-state once the transition period is complete.
The reallocation will take place gradually over 4.5 years with a total of 18 reallocation periods between the start and end-state to avoid market volatility and transition toward the new allocation with minimal network disruption.
Note that this is a hardfork which must be activated by miners. To do this they
should start creating blocks signalling bit 5 in version
field of the block header.
Reallocation periods
Each reallocation period will last three superblock cycles (approximately one quarter). The following table shows the split of the non-proposal block rewards during each period.
Event | Miner | Masternode |
---|---|---|
Now | 50.0% | 50.0% |
1 | 48.7% | 51.3% |
2 | 47.4% | 52.6% |

End | 40.0% | 60.0% |
Dynamic Activation Thresholds
In Dash we have used lower thresholds (80% vs 95% in BTC) to activate upgrades via a BIP9-like mechanism for quite some time. While it's preferable to have as much of the network hashrate to signal update readiness as possible, this can result in quite lengthy upgrades if one large non-upgraded entity stalls all progress. Simply lowering thresholds even further can result in network upgrades being too fast which can potentially cause some chaos. This version implements BIP9-like dynamic activation thresholds which drop from some initial level to a minimally acceptable one over time at an increasing rate. This provides a safe non-blocking way of activating proposals.
This mechanism applies to the Block Reward Reallocation proposal mentioned above for which the threshold will begin at an 80% level and decay down to 60% over the course of 10 periods.
Concentrated Recovery
In the current system, signature shares are propagated to all LLMQ members until one of them has collected enough shares to recover the signature. Until this recovered signature is propagated in the LLMQ, all members will keep propagating shares and verifying each one. This causes significant load on the LLMQ, resulting in decreased throughput, which will be avoided with the new system.
This new system initially sends all shares to a single deterministically selected node, so that this node can recover the signature and propagate the recovered signature. This way only the recovered signature needs to be propagated and verified by all members. Each member, after sending their share to this node, waits for some timeout and then sends their share to another deterministically selected member. This process is repeated until a recovered signature is finally created and propagated.
This timeout begins at two seconds and increases exponentially up to ten seconds
(ie. 2,4,8,10,10
) for each node that times out. This is in order to minimize the time
taken to generate a signature in the case that the recovery node is down, while also
minimizing the traffic generated when the network is under stress.
The new system is activated with the newly added SPORK_21_QUORUM_ALL_CONNECTED
which has two hardcoded values with a special meaning: 0
activates Concentrated
Recovery for every LLMQ and 1
excludes 400_60
and 400_85
quorums.
Increased number of masternode connections
To implement "Concentrated Recovery", it is now required that all members of a LLMQ connect to all other members of the same LLMQ. This significantly increases general connection count for masternodes. These intra-quorum connections are less resource demanding than normal p2p connections as they only exchange LLMQ/masternode related messages, but the hardware and network requirements will still be higher than before.
This change will at first only be activated for the smaller LLMQs (50 members) and then may later be activated for larger quorums (400 members).
This is also controlled via SPORK_21_QUORUM_ALL_CONNECTED
.
Masternode Connection Probing
While each LLMQ member must have a connection to each other member, it's not necessary
for all members to actually connect to all other members. This is because only
one of a pair of two masternodes need to initiate the connection while the other one can
wait for an incoming connection. Probing is done in the case where a masternode doesn't
really need an outbound connection, but still wants to verify that the other side
has its port open. This is done by initiating a short lived connection, waiting
for MNAUTH
to succeed and then disconnecting again.
After this process, each member of a LLMQ knows which members are unable to accept connections, after which they will vote on these members to be "bad".
Masternode Minimum Protocol Version Checks
Members of LLMQs will now also check all other members for minimum protocol versions while in DKG. If a masternode determines that another LLMQ member has a protocol version that is too low, it will vote for the other member to be "bad".
PoSe punishment/banning
If 80% of all LLMQ members voted for the same member to be bad, it is excluded in the final stages of the DKG. This causes the bad masternode to get PoSe punished and then eventually PoSe banned.
Network performance improvements
This version of Dash Core includes multiple optimizations to the network and p2p message
handling code. The most important one is the introduction of epoll
on linux-based
systems. This removes most of the CPU overhead caused by the sub-optimal use of select
,
which could easily use up 50-80% of the CPU time spent in the network thread when many
connections were involved.
Since these optimizations are exclusive to linux, it is possible that masternodes hosted on windows servers will be unable to handle the network load and should consider migrating to a linux based operating system.
Other improvements were made to the p2p message handling code, so that LLMQ related connections do less work than full/normal p2p connections.
Wallet files
The --wallet=<path>
option now accepts full paths instead of requiring
wallets to be located in the -walletdir
directory.
If --wallet=<path>
is specified with a path that does not exist, it will now
create a wallet directory at the specified location (containing a wallet.dat
data file, a db.log
file, and database/log.??????????
files) instead of just
creating a data file at the path and storing log files in the parent
directory. This should make backing up wallets more straightforward than
before because the specified wallet path can just be directly archived without
having to look in the parent directory for transaction log files.
For backwards compatibility, wallet paths that are names of existing data files
in the --walletdir
directory will continue to be accepted and interpreted the
same as before.
When Dash Core is not started with any --wallet=<path>
options, the name of
the default wallet returned by getwalletinfo
and listwallets
RPCs is
now the empty string ""
instead of "wallet.dat"
. If Dash Core is started
with any --wallet=<path>
options, there is no change in behavior, and the
name of any wallet is just its <path>
string.
PrivateSend coin management improvements
A new algorithm for the creation of mixing denominations was implemented which should reduce the number of the smallest inputs created and give users more control on soft and hard caps. A much more accurate fee management algorithm was also implemented which should fix issues for users who have custom fees specified in wallet config or in times when network is under load.
There is a new "PrivateSend" tab in the GUI which allows spending fully mixed coins only. The CoinControl feature was also improved to display coins based on the tab it was opened in, to protect users from accidentally spending mixed and non-mixed coins in the same transaction and to give better overview of spendable mixed coins.
PrivateSend Random Round Mixing
Some potential attacks on PrivateSend assume that all inputs had been mixed for the same number of rounds (up to 16). While this assumption alone is not enough to break PrivateSend privacy, it could still provide some additional information for other methods like cluster analysis and help to narrow results.
With Random Round Mixing, an input will be mixed to N rounds like prior. However, at this point, a salted hash of each input is used to pick ~50% of inputs to be mixed for another round. This rule is then executed again on the new inputs. This results in an exponential decay where if you mix a set of inputs, half of those inputs will be mixed for N rounds, 1/4 will be mixed N+1, 1/8 will be mixed N+2, etc. Current implementation caps it at N+3 which results in mixing an average of N+0.875 rounds and sounds like a reasonable compromise given the privacy gains.
GUI changes
All dialogs, tabs, icons, colors and interface elements were reworked to improve user experience, let the wallet look more consistent and to make the GUI more flexible. There is a new "Appearance setup" dialog that will show up on the first start of this version and a corresponding tab has been added to the options which allows the user to pick a theme and to tweak the font family, the font weight and the font size. This feature specifically should help users who had font size/scaling issues previously.
For advanced users and developers there is a new way to control the wallet's look
by specifying a path to custom css files via --custom-css-dir
. Additionally, the new
--debug-ui
will force Dash Core to reload the custom css files as soon as they get updated
which makes it possible to see and debug all css adjustments live in the running GUI.
From now on the "Pay To" field in "Send" and "PrivateSend" tabs also accepts Dash URIs. The Dash address and the amount from the URI are assigned to corresponding fields automatically if a Dash URI gets pasted into the field.
Sporks
Two new sporks were introduced in this version:
SPORK_21_QUORUM_ALL_CONNECTED
allows to control Concentrated Recovery and Masternode Probing activation;SPORK_22_PS_MORE_PARTICIPANTS
raises the number of users that can participate in a single PrivateSend mixing transaction to 20.
Sporks SPORK_15_DETERMINISTIC_MNS_ENABLED
, SPORK_16_INSTANTSEND_AUTOLOCKS
and SPORK_20_INSTANTSEND_LLMQ_BASED
which were previously deprecated in v0.15
are completely removed now. SPORK_6_NEW_SIGS
was never activated on mainnet
and was also removed in this version.
Build system
The minimum version of the GCC compiler required to compile Dash Core is now 4.8.
The minimum version of Qt is now 5.5.1. Some packages in depends/
as well as
secp256k1
and leveldb
subtrees were updated to newer versions.
