    This is a new major version release, including various bug fixes and performance improvements, as well as updated translations.

    Please report bugs using the issue tracker at github:


    Mandatory Update

    PIVX Core v2.3.0 is a mandatory update for all users. This release contains validation and security improvements that are not backwards compatible with older versions. Users will have a grace period of no less than two weeks to update their clients before enforcement of this update is enabled.

    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/PIVX-Qt (on Mac) or pivxd/pivx-qt (on Linux).


    PIVX Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows Vista and later.

    Microsoft ended support for Windows XP on April 8th, 2014, No attempt is made to prevent installing or running the software on Windows XP, you can still do so at your own risk but be aware that there are known instabilities and issues. Please do not report issues about Windows XP to the issue tracker.

    PIVX Core should also work on most other Unix-like systems but is not frequently tested on them.

    Notable Changes

    RPC changes

    masternode command

    The masternode RPC command has been re-worked to ease it's usage and return valid JSON in it's results. The following is an overview of the changed command parameters:

    Removed (did nothing)
    The optional "mode" paramater has been removed. Command now always outputs full details in JSON format.
    Result fields changed: IP:Port removed, vin renamed to txhash
    Result is now an array of objects, instead of an object of objects
    Added additional fields for txhash, outputidx, netaddr, and message

    outputs n objects
    winners n objects. See below
    list masternode list is the same as masternodelist. See below

    For the winners parameter, the results are now in a standard JSON format as follows:

        nHeight: n,           (int) block height
        winner: {
            address: addr,    (string) PIVX MN Address,
            nVotes: n,        (int) Number of votes for winner,

    In the case of multiple winners being associated with a single block, the results are in the following format (the winner object becomes an array of objects):

        nHeight: n,           (int) block height,
        winner: [
            address: addr,    (string) PIVX MN Address,
            nVotes: n,        (int) Number of votes for winner,

    For the list (aka masternodelist) parameter, the various "modes" have been removed in favor of a unified and standardized result format. The result is now an array of objects instead of an object of objects. Further, the individual objects now have a standard JSON format. The result format is as follows:

        "rank": n,         (numeric) Masternode rank (or 0 if not enabled)
        "txhash": hash,    (string) Collateral transaction hash
        "outidx": n,       (numeric) Collateral transaction output index
        "status": s,       (string) Status (ENABLED/EXPIRED/REMOVE/etc)
        "addr": addr,      (string) Masternode PIVX address
        "version": v,      (numeric) Masternode Protocol version
        "lastseen": ttt,   (numeric) The time in seconds since epoch (Jan 1 1970 GMT) the masternode was last seen
        "activetime": ttt, (numeric) The time in seconds since epoch (Jan 1 1970 GMT) masternode has been active
        "lastpaid": ttt,   (numeric) The time in seconds since epoch (Jan 1 1970 GMT) masternode was last paid

    mnbudget command

    An additional parameter has been added to mnbudget to allow a controller wallet to issue per-MN votes. The new parameter is vote-alias and it's use format is as follows:

    mnbudget vote-alias <proposal-hash> <yes|no> <alias>

    All fields are required to successfully vote.

    walletpassphrase command

    CLI users that are staking their coins will now have the option of unlocking the wallet with no re-lock timeout. Similar to using 9999999 as the timeout, the walletpassphrase command now accepts 0 as a timeout to indicate that no re-locking should occur based on elapsed time.

    Usage: walletpassphrase <passphrase> 0 <true|false>

    The third parameter indicates if the wallet should be unlocked for staking and anonymization only (true), or to allow send operations (false, full unlock).

    ZeroMQ (ZMQ) Notifications

    pivxd can now (optionally) asynchronously notify clients through a ZMQ-based PUB socket of the arrival of new transactions and blocks. This feature requires installation of the ZMQ C API library 4.x and configuring its use through the command line or configuration file. Please see docs/zmq.md for details of operation.

    All Masternodes List GUI Removal

    With the standardization and reformatting of the masternode list (masternodelist) RPC command, there is no real use case to keep the full list of masternodes in the GUI. This GUI element causes a great deal of extra overhead, even when it is not being actively displayed. The removal of this list has also proven to resolve a number of linux-based errors

    Note that the GUI list of masternodes associated with a controller wallet remains intact.

    SPV Client Support

    PIVX Core now enables bloom filters by default to support SPV clients like mobile wallets. This feature can be disabled by using the -peerbloomfilters option on startup.
