Dash Core version 0.14.0.0

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.

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). 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.

Downgrade warning

Downgrade to a version < 0.13.0.0

Downgrading to a version smaller than 0.13 is not supported anymore as DIP2/DIP3 has activated on mainnet and testnet.

Downgrade to versions 0.13.0.0 - 0.13.3.0

Downgrading to 0.13 releases is fully supported until DIP0008 activation but is not recommended unless you have some serious issues with version 0.14.

Notable changes

DIP0004 - Coinbase Payload v2

Coinbase Payload v2 introduces new field merkleRootQuorums which represents the merkle root of all the hashes of the final quorum commitments of all active LLMQ sets. This allows SPV clients to verify active LLMQ sets and use this information to further verify ChainLocks and LLMQ-based InstantSend messages. Coinbase Payload v2 relies on DIP0008 (bit 4) activation.

DIP0008 - ChainLocks

This version introduces ChainLocks, a technology for near-instant confirmation of blocks and finding near-instant consensus on the longest valid/accepted chain. ChainLocks leverages LLMQ Signing Requests/Sessions to accomplish this. ChainLocks relies on DIP0008 (bit 4) activation and SPORK_19_CHAINLOCKS_ENABLED spork.

DIP0010 - LLMQ-based InstantSend

InstantSend is a feature to allow instant confirmations of payments. It works by locking transaction inputs through masternode quorums. It has been present in Dash for a few years and been proven to work. Nevertheless, there are some limits which could theoretically be removed in the old system but doing so would have created risks in terms of scalability and security.

We introduce LLMQ-based InstantSend which is designed to be much more scalable without sacrificing security and which allows all transactions to be treated as InstantSend transactions. The old system differentiated transactions as InstantSend transactions by using the P2P message “ix” instead of “tx”. Since this distinction is not required in the new system, the P2P message “ix” will be removed after DIP0008 deployment (for now, transactions sent via "ix" message will be relayed further via "tx" message).

Network

Legacy messages mnw, mnwb, mnget, mnb, mnp, dseg, mnv, qdcommit and their corresponding inventory types (7, 10, 14, 15, 19, 22) are no longer suported.

Message version is extended with a 256 bit field - a challenge sent to a masternode. Masternode which received such a challenge must reply with new p2p message mnauth directly after verack. This mnauth message must include a signed challenge that was previously sent via version.

Mining

Due to changes in coinbase payload this version requires for miners to signal their readiness via BIP9-like mechanism - by setting bit 4 of the block version to 1. Note that if your mining software simply uses coinbase_payload field from getblocktemplate RPC and doesn't construct coinbase payload manually then there should be no changes to your mining software required. We however encourage pools and solo-miners to check their software compatibility on testnet to ensure flawless migration.

PrivateSend

The wallet will try to create and consume denoms a bit more accurately now. It will also only create a limited number of inputs for each denominated amount to prevent bloating itself with mostly the smallest denoms. You can control this number of inputs via new -privatesenddenoms cmd-line option (default is 300).

InstantSend

Legacy InstantSend is going to be superseded by the newly implemented LLMQ-based one once DIP0008 (bit 4) is active and SPORK_20_INSTANTSEND_LLMQ_BASED spork is ON.

Sporks

There are two new sporks introduced in this version - SPORK_19_CHAINLOCKS_ENABLED and SPORK_20_INSTANTSEND_LLMQ_BASED. SPORK_17_QUORUM_DKG_ENABLED was introduced in v0.13 but was kept OFF. It will be turned on once 80% masternodes are upgraded to v0.14 which will enable DKG and DKG-based PoSe.

QR codes

Wallet can now show QR codes for addresses in the address book, receiving addresses and addresses identified in transactions list (right click -> "Show QR-code").

RPC changes

There are a few changes in existing RPC interfaces in this release:

• for blockchain based RPC commands instantlock will say true if the transaction was locked via LLMQ based ChainLocks (for backwards compatibility reasons)
• prioritisetransaction no longer allows adjusting priority
• getgovernanceinfo no longer has masternodewatchdogmaxseconds and sentinelpingmaxseconds fields
• masternodelist no longer supports activeseconds, daemon, lastseen, protocol, keyid, rank and sentinel modes, new mode - pubkeyoperator
• masternode count no longer has ps_compatible and qualify fields and ps and qualify modes
• masternode winner and masternode current no longer have protocol, lastseen and activeseconds fields, new field - proTxHash
• debug supports new categories: chainlocks, llmq, llmq-dkg, llmq-sigs
• mnsync no longer has IsMasternodeListSynced and IsWinnersListSynced fields
• various RPCs that had instantlock field have chainlock (excluding mempool RPCs) and instantlock_internal fields now

There are also new RPC commands:

• bls fromsecret parses a BLS secret key and returns the secret/public key pair
• quorum is a set of commands for quorums/LLMQs e.g. list to show active quorums (by default, can specify different count) or info to shows detailed information about some specific quorum etc., see help quorum

Few RPC commands are no longer supported: estimatepriority, estimatesmartpriority, gobject getvotes, masternode start-*, masternode genkey, masternode list-conf, masternode check, masternodebroadcast, sentinelping

See help command in rpc for more info.

ZMQ changes

Added two new messages hashchainlock and rawchainlock which return the hash of the chainlocked block or the raw block itself respectively.

Command-line options

Changes in existing cmd-line options:

• -bip9params supports optional window and threshold values now

New cmd-line options:

• -watchquorums
• -privatesenddenoms
• -dip3params (regtest-only)
• -llmqchainlocks (devnet-only)

Few cmd-line options are no longer supported: -limitfreerelay, -relaypriority, -blockprioritysize, -sendfreetransactions, -mnconf, -mnconflock, -masternodeprivkey

See Help -> Command-line options in Qt wallet or dashd --help for more info.

Miscellaneous

A lot of refactoring, backports, code cleanups and other small fixes were done in this release.
