Dash Core version v23.1.0

This is a new minor version release, bringing new features, important bugfixes, and significant performance improvements. This release is highly recommended for all nodes. All Masternodes are required to upgrade.

Please report bugs using the issue tracker at GitHub:

https://github.com/dashpay/dash/issues

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).

Downgrade warning

Downgrade to a version < v23.0.0

Downgrading to a version older than v23.0.0 is not supported, and will require a reindex.

Notable changes

InstantSend performance improvements

This release includes a collection of changes that significantly improve InstantSend lock latency. When fully adopted across the network, these changes are expected to reduce average InstantSend lock times by 25-50%, bringing average lock confirmation times down to near 1 second. Key improvements include:

  • Quorum message prioritization: Network message processing now separates quorum-related messages (DKG contributions, signing shares, recovered signatures, ChainLock signatures, InstantSend locks) into a dedicated priority queue. This ensures consensus-critical quorum operations are processed with lower latency than regular network traffic. (#6952)
  • Proactive recovered signature relay: Recovered signatures are now proactively pushed to connected nodes rather than waiting for them to be requested. InstantSend quorums are now fully connected for recovered signature relay, reducing the number of network hops required for IS lock propagation. (#6967)
  • Multi-threaded signing shares processing: The CSigSharesManager has been enhanced with a multi-threaded worker pool and dispatcher for parallel processing of signing shares, improving throughput during periods of high signing activity. (#7004)
  • InstantSend height caching: Block heights are now cached in a dedicated LRU cache, significantly reducing contention on cs_main during InstantSend lock verification. (#6953)
  • Shared mutex conversions: The m_nodes_mutex and m_peer_mutex have been converted from recursive mutexes to shared mutexes, allowing concurrent read access from multiple threads. This reduces lock contention for the most frequent network operations. (#6912, #6468)
  • Reduced redundant work: Peers that have requested recovered signature relay are no longer sent redundant ISDLOCK inventory announcements. Redundant signature validation during signing share processing has been eliminated. (#6994, #6958)

GUI refresh

The Masternode tab has been significantly overhauled with new status icons reflecting masternode ban state, type and ban filters, context menus replacing address columns, elastic column widths, and a detailed masternode description dialog. A dedicated masternode model now backs the list view. (#7116)

The Governance and Masternode tabs can now be shown or hidden at runtime through the Options dialog without requiring a client restart. The proposal model has been split out for better separation of concerns. (#7112)

Dust attack protection

A new GUI option allows users to enable automatic dust attack protection. When enabled, small incoming transactions from external sources that appear to be dust attacks are automatically locked, excluding them from coin selection. Users can configure the dust threshold in the Options dialog. (#7095)

Descriptor wallets no longer experimental

Descriptor-based wallets have been promoted from experimental status to a fully supported wallet type. Users can now create and use descriptor wallets without the experimental warning. (#7038)

GUI settings migration

Configuration changes made in the Dash GUI (such as the pruning setting, proxy settings, UPNP preferences) are now saved to <datadir>/settings.json rather than to the Qt settings backend (Windows registry or Unix desktop config files), so these settings will now apply to dashd as well, instead of being ignored.

Settings from dash.conf are now displayed normally in the GUI settings dialog, instead of in a separate warning message. These settings can now be edited because settings.json values take precedence over dash.conf values. (#6833)

Other notable changes

  • Masternodes now trickle transactions to non-masternode peers (as regular nodes do) rather than sending immediately, reducing information leakage while maintaining fast masternode-to-masternode propagation. (#7045)
  • The Send Coins dialog now warns users when sending to duplicate addresses in the same transaction. (#7015)
  • External signer (hardware wallet) support has been added as an experimental feature, allowing wallets to delegate signing to HWI-compatible external devices. (#6019)
  • Improved wallet encryption robustness and HD chain decryption error logging. (#6938, #6944, #6945, #6939)
  • Peers that re-propagate stale quorum final commitments (QFCOMMIT) are now banned starting at protocol version 70239. (#7079)
  • Various race conditions in ChainLock processing have been fixed. (#6924, #6940)

P2P and network changes

  • PROTO_VERSION has been bumped to 70240 with the introduction of protocol version-based negotiation of BIP324 v2 transport short IDs for Dash-specific message types. The PLATFORMBAN message has been added to the v2 P2P short ID mapping (short ID 168). When communicating with peers supporting version 70240+, this message uses 1-byte encoding instead of 13-byte encoding, reducing bandwidth. Compatible peers use compact encoding, while older v2 peers automatically fall back to long encoding. (#7082)

Updated RPCs

  • quorum dkginfo now requires that nodes run in either watch-only mode (-watchquorums) or as an active masternode, as regular nodes do not have insight into network DKG activity. (#7062)
  • quorum dkgstatus no longer emits the return values time, timeStr and session on nodes that do not run in either watch-only or masternode mode. (#7062)
  • The getbalances, gettransaction and getwalletinfo RPCs now return a lastprocessedblock JSON object containing the wallet's last processed block hash and height at the time the result was generated. (#6901)
  • Fixed the BLS scheme selection in protx revoke and protx update_service to use the actual deployment state rather than hardcoded values. (#7096)
  • Fixed protx register to include the Prepare action for wallet unlock checks. (#7069)
  • Added a new next_index field in the response in listdescriptors to have the same format as importdescriptors (#6780)

Changes to wallet related RPCs can be found in the Wallet section below.

Updated settings

  • The shutdownnotify option is used to specify a command to execute synchronously before Dash Core has begun its shutdown sequence. (#6901)

Build System

  • Dash Core binaries now target Windows 10 and macOS 14 (Sonoma), replacing the previous targets of Windows 7 and macOS 11 (Big Sur). (#6927)
  • The minimum supported Clang version has been bumped to Clang 19 for improved C++20 support and diagnostics. (#6995)

Wallet

  • CoinJoin denomination creation now respects the wallet's "avoid_reuse" setting. When the wallet has avoid_reuse enabled, change is sent to a fresh change address to avoid address/public key reuse. Otherwise, change goes back to the source address (legacy behavior). (#6870)
  • CoinJoin masternode tracking (vecMasternodesUsed) is now shared across all loaded wallets instead of per-wallet, improving mixing efficiency. (#6875)

GUI changes

  • Masternode tab redesigned with new status icons, type/ban filters, context menus, elastic column widths, and detailed masternode description dialog. (#7116)
  • Runtime show/hide of Governance and Masternode tabs through Options without restart. (#7112)
  • Dust attack protection option added to Options dialog. (#7095)
  • Duplicate recipient warning in Send Coins dialog. (#7015)
  • Auto-validation of governance proposals as fields are filled in. (#6970)
  • Wallet rescan option now available when multiple wallets are loaded (rescan remains one wallet at a time). (#7072)
  • Improved CreateWalletDialog layout. (#7039)
  • Dash-specific font infrastructure extracted to dedicated files with FontInfo and FontRegistry classes, supporting arbitrary fonts and dynamic font weight resolution. (#7068, #7120)
  • Fixed precision loss in proposal generation. (#7134)
  • Fixed crash when changing themes after mnemonic dialog was shown. (#7126)
