v3.0.2

PIVX Core version 3.0.2 is now available from:

https://github.com/pivx-project/pivx/releases

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

Please report bugs using the issue tracker at github:

https://github.com/pivx-project/pivx/issues

Recommended Update

PIVX Core v3.0.2 is a recommended, semi-mandatory update for all users. This release contains transaction creation bug fixes for zPIV spends, automint calculation adjustments, and other various updates/fixes.

zPIV spending requires this update.

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).

Compatibility

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.

❗❗❗ MacOS 10.13 High Sierra ❗❗❗

Currently there are issues with the 3.0.x gitian releases on MacOS version 10.13 (High Sierra), no reports of issues on older versions of MacOS.

Notable Changes

Auto Wallet Backup

In addition to the automatic wallet backup that is done at each start of the client, a new automatic backup function has been added that will, by default, create a backup of the wallet file during each zPIV mint operation (zPIV spends which re-mint their change are also included in this). This functionality is controlled by the -backupzpiv command-line option, which defaults to 1 (enabled, auto-backup).

Users that wish to prevent this behavior (not recommended) can pass -backupzpiv=0 at the command-line when starting the client, or add backupzpiv=0 to their pivx.conf file.

zPIV Automint Calculations

A bug in the automint calculations was made apparent on mainnet when block times exceeded expectations, resulting in zPIV mint transactions that were in an unconfirmed state to still be treated as if they had never been minted. This caused automint to effectively mint more than what was intended.

zPIV Spending Fix

The size of zPIV spend transactions is knowingly larger than normal transactions, and while this was expected, a much stricter check against the scriptsig size is used for mainnet, causing the transactions to be rejected by the mempool, and thus not being packaged into any blocks.

zPIV Transaction Recovery

Due to the aforementioned issue with zPIV spending, users may find that their attempted spends are now conflicted and zPIV balances are not represented as expected. "Recovery" of these transactions can be done using the following methods:

GUI:

The Privacy tab has the Reset and Rescan buttons that can be used to restore these mints/spends from a state of being marked as unavailable.
RPC:

The RPC commands resetspentzerocoin and resetmintzerocoin are the command-line counterparts to the above, and can be used by users that do not use the GUI wallet.

RPC Changes

The bip38decrypt command has had it's parameter order changed to be more consistent with it's counterpart. The command now expects the PIVX address as it's first parameter and the passphrase as it's second parameter.

Bip38 Compatibility With 3rd Party Tools

The in-wallet bip38 encryption method was leaving the final 4 bytes of the encrypted key blank. This caused an incompatibility issue with 3rd party tools like the paper wallet generators that could decrypt bip38 encrypted keys. Cross-tool compatibility has now been restored.

v3.0.0

1269ce8

v3.0.0

PIVX Core version 3.0.0 is now available from:

https://github.com/pivx-project/pivx/releases

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:

https://github.com/pivx-project/pivx/issues

Mandatory Update

PIVX Core v3.0.0 is a mandatory update for all users. This release contains new consensus rules and improvements that are not backwards compatible with older versions. Users will have a grace period of one week to update their clients before enforcement of this update is enabled.

Users updating from a previous version after the 13th of October will require a full resync of their local blockchain from either the P2P network or by way of the bootstrap.

How to Upgrade

Compatibility

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

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

❗❗❗ MacOS 10.13 High Sierra ❗❗❗

Currently there are issues with the 3.0.0 gitian release on MacOS version 10.13 (High Sierra), no reports of issues on older versions of MacOS.

Notable Changes

Zerocoin (zPIV) Protocol

At long last, the zPIV release is here and the zerocoin protocol has been fully implemented! This allows users to send transactions with 100% fungible coins and absolutely zero history or link-ability to their previous owners.

The Zerocoin protocol allows user to convert (mint) their PIV to zerocoins, which we call zPIV. When zPIV are converted back to PIV there is no trail associated with the coins being sent, such as who originally minted those coins. Essentially the only thing the receiver of the zPIV transaction will see is that it came from the zerocoin protocol.

zPIV Denominations

zPIV comes in specific denominations of 1, 5, 10, 50, 100, 500, 1000, and 5000. A denomination is a similar concept to paper currency, where you can hold a $100 bill but there is no available $99 bill for you to hold.

Other implementations of the zerocoin protocol only allow for spending of one denomination/zerocoin at a time. The PIVX implementation of zerocoin allows users to spend any amount of zPIV they would like (with certain limitations). If a user held two denominations of 5 and they send 7.75 to a merchant, the wallet will automatically grab the two denominations of 5 and then issue 2.25 PIV in change to the spender. There is currently a limit of up to 6 individual zerocoin coins that can be combined into a spend, where each coin could be a different or similar denomination

The PIVX zerocoin implementation is structured in such a way that denominations aren't needed to be known by the average user.

Fees

zPiv transactions require more computation and disk space than typical PIVX transactions, and as such require a higher transaction fee in order to prevent network spam. Fees are only charged when minting zPiv, each minted denomination is charged a flat rate of 0.01 Piv. zPiv spends are not charged a transaction fee unless the change is minted into zPiv, see the Minting Change section for details on fees for zPiv spends with minted change.

Converting PIV to zPIV (zPIV Mint)

GUI - Conversion from PIV to zPIV can be done using the Privacy Dialog in the QT wallet. Enter the amount of PIV you would like to convert and click Mint Zerocoin.

RPC - Conversion from PIV to zPIV can be done using the mintzerocoin command.

Automint - The PIVX wallet is set to convert 10% of the wallets available PIV to zPIV automatically. This can be adjusted in the GUI within the Options dialog, which allows the preferred % to be adjusted as well as the ability to set the preferred zPIV denomination that will be minted. Automint is set to be triggered when additional blocks are added to the block chain and is programmed not to convert your coins all at once.

Automint can be disabled by adding enablezeromint=0 to the wallet configuration file. The preferred mint % and denomination can also be set by the configuration file using zeromintpercentage=<n> and preferredDenom=<n>.

Converting zPIV to PIV (zPIV Spend)

Redeeming zPIV is done by converting it back to PIV. With the 3.0.0 software release, users are not able to send zPIV to each other directly in an atomic fashion.

GUI - Conversion from zPIV to PIV can be done using the Privacy Dialog in the QT wallet. Enter a PIVX address that you would like to Pay To, enter the amount of PIV the receiver should be sent, click Spend Zerocoin.

RPC - Conversion from zPIV to PIV can be done using the spendzerocoin command.

Advanced Use & Privacy Considerations

Security Level - When spending zPIV, a user is prompted to enter a Security Level choosing from 1-100. In an indirect way, the Security Level parameter allows the user to choose how many coins to obfuscate their transaction with.

A Security Level of 1 for example would take all of the minted coins in the blockchain before your mint was added to the blockchain, and would then add any coins that were minted within the next 10 blocks as well. A Security Level of 2 would do the same thing, except add the next 20 blocks worth of mints. A Security Level of 100 will add the maximum amount of mints up to the current end of the blockchain.

The higher the Security Level, the more computation and time it will take to spend. Although it takes longer, a level of 100 is recommended for transactions that need maximum anonymity.

Minting Change - The PIVX implementation of the zerocoin protocol also allows the spender to choose how to receive their leftover change from a Spend transaction. For maximum anonymity it is recommended that the spender choose to receive the change in zPIV, which prevents situations where change from a zPIV spend that is redeemed in PIV is accidentally mixed with the rest of the users PIV, thus linking transactions back to a PIVX address.

Since the lowest denomination of zPIV is 1, and a fee is required to mint zPIV, in most situations a high fee will be paid to mint change. The fee is the remainder of the change that cannot be converted back to zPIV. For example this would mean a spending a denomination of 10 that yields change of 6.75 in change, would issue zPIV denominations of 5 and 1 back to the sender with the remaining 0.75 that is unmintable being contributed as a fee.

zPIV Control
Similar to the concept of Coin Control in the QT wallet, zPIV Control allows users to select exactly which zPIV mints they would like to spend. This gives a flexibility to choose which denominations can be picked for a spend that wouldn't otherwise be available.

Tor Service Integration Improvements

Integrating with Tor is now easier than ever! Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. PIVX Core has been updated to make use of this.

This means that if Tor is running (and proper authorization is available), PIVX Core automatically creates a hidden service to listen on, without manual configuration. PIVX Core will also use Tor automatically to connect to other .onion nodes if the control socket can be successfully opened. This will positively affect the number of available .onion nodes and their usage.

This new feature is enabled by default if PIVX Core is listening, and a connection to Tor can be made. It can be configured with the -listenonion, -torcontrol and -torpassword settings. To show verbose debugging information, pass -debug=tor.

`startmasternode` Command

This command now handles all cases for starting a masternode instead of having multiple commands based on the context. Command arguments have changed slightly to allow the user to decide wither or not to re-lock the wallet after the command is run. Below is the help documentation:

startmasternode "local|all|many|missing|disabled|alias" lockwallet ( "alias" )

 Attempts to start one or more masternode(s)

Arguments:
1. set         (string, required) Specify which set of masternode(s) to start.
2. lockWallet  (boolean, required) Lock wallet after completion.
3. alias       (string) Masternode alias. Required if using 'alias' as the set.

Result: (for 'local' set):
"status"     (string) Masternode status message

Result: (for other sets):
{
  "overall": "xxxx",     (string) Overall status message
  "detail": [
    {
      "node": "xxxx",    (string) Node name or alias
      "result": "xxxx",  (string) 'success' or 'failed'
      "error": "xxxx"    (string) Error message, if failed
    }
    ,...
  ]
}

Examples:
> pivx-cli startmasternode "alias" true "my_mn"
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "startmasternode", "params": ["alias" true "my_mn"] }' -H 'content-type: text/plain;' http://127.0.0.1:51473/

`preparebudget` & `submitbudget` Commands

Due to the requirement of maintaining backwards compatibility with the legacy command, these two new commands are created to handle the preparation/submission of budget proposals. Future intention is to roll these two commands back into a single command to reduce code-duplication. Paramater arguments currently remain unchanged from the legacy command equivilent.

`mnbudgetvote` Command

This command now handles all cases for submitting MN votes on a budget proposal. Backwards compatibility with the legacy command(s) has been retained, with the exception of the vote-alias case due to a conflict in paramater type casting. A user running mnbudget vote-alias will be instructed to instead use the new mnvote command. Below is the full help documentation for this new command:

mnbudgetvote "local|many|alias" "votehash" "yes|no" ( "alias" )

Vote on a budget proposal

Arguments:
1. "mode"      (string, required) The voting mode. 'local' for voting directly from a masternode, 'many' for voting with a MN controller and casting the same vote for each MN, 'alias' for voting with a MN controller and casting a vote for a single MN
2. "votehash"  (string, required) The vote hash for the proposal
3. "votecast"  (string, required) Your vote. 'yes' to vote for the proposal, 'no' to vote against
4. "alias"     (string, required for 'alias' mode) The MN alias to cast a vote for.

Result:
{
  "overall": "xxxx",      (string) The overall status message for the vote cast
  "detail": [
    {
      "node": "xxxx",      (string) 'local' or the MN alias
      "result": "xxxx",    (string) Either 'Success' or 'Failed'
      "error": "xxxx",     (string) Error message, if vote failed
    }
    ,...
  ]
}

Examples:
> pivx-cli mnbudgetvote "local" "ed2f83cedee59a91406f5f47ec4d60bf5a7f9ee6293913c82976bd2d3a658041" "yes"
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "mnbudgetvote", "params": ["local" "ed2f83cedee59a91406f5f47ec4d60bf5a7f9ee6293913c82976bd2d3a658041" "yes"] }' -H 'content-type: text/plain;' http://127.0.0.1:51473/

`getbudgetinfo` Command

This command now combines the old mnbudget show and mnbudget getinfo commands to reduce code duplication while still maintaining backwards compatibility with the legacy commands. Given no parameters, it returns the full list of budget proposals (mnbudget show). A single optional parameter allows to return information on just that proposal (mnbudget getinfo). Below is the full help documentation:

getbudgetinfo ( "proposal" )

Show current masternode budgets

Arguments:
1. "proposal"    (string, optional) Proposal name

Result:
[
  {
    "Name": "xxxx",               (string) Proposal Name
    "URL": "xxxx",                (string) Proposal URL
    "Hash": "xxxx",               (string) Proposal vote hash
    "FeeHash": "xxxx",            (string) Proposal fee hash
    "BlockStart": n,              (numeric) Proposal starting block
    "BlockEnd": n,                (numeric) Proposal ending block
    "TotalPaymentCount": n,       (numeric) Number of payments

v2.3.0

3ef8346

v2.3.0

PIVX Core version 2.3.0 is now available from:

https://github.com/pivx-project/pivx/releases

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:

https://github.com/pivx-project/pivx/issues

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

Compatibility

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:

Command Parameter	Changes
`budget`	Removed (did nothing)
`count`	The optional "mode" paramater has been removed. Command now always outputs full details in JSON format.
`current`	Result fields changed: IP:Port removed, vin renamed to txhash
`list-conf`	Result is now an array of objects, instead of an object of objects
`outputs`	Result is now an array of objects instead of a list of n objects
`status`	Added additional fields for txhash, outputidx, netaddr, and message
`winners`	Result is now an array of objects instead of a list of n objects. See below
`list`	Remove all optional "modes" and standardized the results. Note: `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.

v2.2.1

c23ceb4

v2.2.1

PIVX Core version 2.2.1 is now available from:

https://github.com/pivx-project/pivx/releases

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

Please report bugs using the issue tracker at github:

https://github.com/pivx-project/pivx/issues

Compatibility

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

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

Notable Changes

Block Data Corruption

Additional startup procedures have been added to fix corrupted blockchain databases.
The majority of users that are experiencing #106 (ConnectBlock() assertion on startup)
that have tested the new wallet have reported that their corrupt blockchain has
successfully been repaired. The new code will automatically detect and repair the
blockchain if it is able to.

If users still experience corruptions with the new wallet and it is not fixed
with the new startup procedures, it is suggested that they try using the
-forcestart startup flag which will bypass the new procedures altogether, and
in rare cases allow the wallet to run. If the database is not fixed by either
the automatic procedures or the -forcestart flag, the user should resync the
blockchain.

Additional progress has been made to prevent the wallet crashes that are causing
the corrupted databases, for example removing the Trading Window (explained below)
and fixing several other minor memory leaks that were inherited from the version
of Bitcoin that PIVX was forked from.

RPC Changes

Exporting or dumping an addresses' private key while the wallet is unlocked for
anonymization and Staking only is no longer possible.
A new command (getstakingstatus) has been added that returns the internal conditions
for staking to be activated and their status.
KeePass integration has been removed for the time being due to various inefficiencies
with it's code.

Trading Window Removed

The Bittrex trading window in the GUI wallet was problematic with it's memory
handling, often leaking, and was overall an inefficient use of resources in it's
current implementation. A revised multi-exchange trading window may be implemented
at a later date.

2.2.1 Change log

RPC and other APIs

#130 ccb1526 [RPC] Add getstakingstatus method
#138 4319af3 [RPC] Require password when using UnlockAnonymizeOnly
#142 6b5cf7f [RPC] Remove Keepass code due to Valgrind warnings

Block and Transaction Handling

#146 bce67cb [Wallet] Look at last CoinsView block for corruption fix process
#154 1b3c0d7 [Consensus] Don't pass the genesis block through CheckWork

P2P Protocol and Network Code

#168 ac912d9 [Wallet] Update checkpoints with v2.2 chain
#162 0c0d080 Remove legacy Dash code IsReferenceNode
