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.

Due to the changes in the "evodb" database format introduced in this release, 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.

Notable changes

Database space usage improvements

Version 0.13.0.0 introduced a new database (evodb) which is found in the datadir of Dash Core. It turned out that this database grows quite fast when a lot of changes inside the deterministic masternode list happen, which is for example the case when a lot PoSe punishing/banning is happening. Such a situation happened immediately after the activation LLMQ DKGs, causing the database to grow a lot. This release introduces a new format in which information in "evodb" is stored, which causes it grow substantially slower.

Version 0.14.0.0 also introduced a new database (llmq) which is also found in the datadir of Dash Core. This database stores all LLMQ signatures for 7 days. After 7 days, a cleanup task removes old signatures. The idea was that the "llmq" database would grow in the beginning and then stay at an approximately constant size. The recent stress test on mainnet has however shown that the database grows too much and causes a risk of out-of-space situations. This release will from now also remove signatures when the corresponding InstantSend lock is fully confirmed on-chain (superseded by a ChainLock). This should remove >95% of all signatures from the database. After the upgrade, no space saving will be observed however as this logic is only applied to new signatures, which means that it will take 7 days until the whole "llmq" database gets to its minimum size.

DKG and LLMQ signing failures fixed

Recent stress tests have shown that masternodes start to ban each other under high load and specific situations. This release fixes this and thus makes it a highly recommended upgrade for masternodes.

MacOS: macOS: disable AppNap during sync and mixing

AppNap is disabled now when Dash Core is syncing/reindexing or mixing.

Signed binaries for Windows

This release is the first one to include signed binaries for Windows.

New RPC command: quorum memberof

This RPC allows you to verify which quorums a masternode is supposed to be a member of. It will also show if the masternode succesfully participated in the DKG process.

More information about number of InstantSend locks

The debug console will now show how many InstantSend locks Dash Core knows about. Please note that this number does not necessarily equal the number of mempool transactions.

The "getmempoolinfo" RPC also has a new field now which shows the same information.
