Community Fund Stability Patches

NavCoin v4.7.2 Release Notes

Fix for Verify Chain

<Pull Request 634>
<Commit 049978e>

This patch fixes Issue 630 and introduces several important changes.

  • New RPC command getcfunddbstatehash covered by functional test cfunddb-statehash.py
  • New state for payment requests 6 when those are paid.
  • The payment request parameter paidOnBlock is substituted by stateChangedOnBlock when state is 6
  • New structure for storing the state history of CFundDB entries. Those are stored in a map associating blockhash and state, allowing to directly revert state transitions when reorganizations are seen.
  • verifychain now checks for the consistency of the CFundDB state hash when level 4 is specified.

IMPORTANT

This set of changes will require older clients to reindex on launch, keeping the node offline for some hours at best. In order to reduce downtime, node operators can proceed as follows if needed:

  • Close node with old version.
  • mkdir /tmp/reindexdata; cp -rf <data_folder>/blocks /tmp/reindexdata/; cp -rf <data_folder>/chainstate /tmp/reindexdata/
  • Reopen node with old version. It will be again online
  • Launch in parallel a second instance of the node, this time using the new version with the parameters -reindex -datadir=/tmp/reindexdata/
  • Once the reindex finishes, close both nodes and copy back the reindexed data.
  • rm -rf <data_folder>/blocks <data_folder>/chainstate; cp -rf /tmp/reindexdata/* <data_folder>
  • Relaunch new version of the node.

Community Fund Nullified Entry Patch

NavCoin v4.7.1 Release Notes

Fix CFund DB read after nullified entry

<Pull Request 608>
<Commit 07d49bf2>

This patch fixes a bug where a cfund database entry that was previously deleted is still persisting, preventing future writes of the entry. This can happen in a scenario where a proposal is included in a block which is invalidated (because of a reorganization) which is then included in a new block as part of the new longest chain.

This fix is the main purpose of the 4.7.1 patch release, while preparing this bugfix there were several other PR's merged which are also included in this release.

On some versions of OSX the background images of the menu buttons render incorrectly and appear pink.

This issue is cosmetic only and the navcoin core developers are working to resolve these issues in a forthcoming release.

NavCoin Core 4.7.0 - Purple Zebra

Purple Zebra Release Notes

Purple Zebra is the culmination of the last few months of work on NavCoin Core and includes 40 closed pull requests, many new features and important security updates & stability fixes. Due to the security patches, upgrading to Purple Zebra should be considered mandatory and performed as soon as possible, especially if you are staking.

Added password prompt for CFund payment/proposal dialogs

<Pull Request 474>
<Commit aa4bbaa>

Peviously you would have to unlock the wallet via the console or debug window before it was possible to create a proposal or payment request through the graphical interface. Now there is a dialog to unlock the wallet while using the Community Fund GUI.

Use of the CoinsDB for the Community Fund

<Pull Request 487>
<Commit a8f425b>

Previously the community fund data was stored in a seperate local database to the rest of the coin data. The data has now been migrated to be part of the CoinsDB which should increase performance and mitigate the data consistency issues that some users were experiencing.

Added error log tab in debug window

<Pull Request 466>
<Commit bed76b9>

You can now see errors which are logged to the debug.log file in the debug window of navcoin-qt. Users no longer have to manually read or search the debug.log via command line to find error messages.

Added some new FIAT currencies and enabled auto price update

<Pull Request 469>
<Commit 5ee24af>

30 Fiat can now be configured as the display units through of navcoin-qt. The issue causing the sockets polling for exchange rates not to close correctly has also been resolved which prevents the wallet from eventually crashing.

Added new progress ui for sync

<Pull Request 526>
<Commit 42769b2>

When the wallet starts and detects it is still catching up to the latest block a progress overlay will be presented to the user. The user can close the overlay but it is now clearer that the wallet is still syncing and the balances will be incorrect until syncing finishes.

NavCoin Core v4.6.0 - Community Fund UI

NavCoin v4.6.0 Release Notes

Community Fund UI

<Pull Request 428>
<Commit cbffaee>

  • Added a Community Fund tab to the core wallet
  • Ability to view and filter proposals and payment request
  • Proposals and payment requests can be voted on and created
  • Removed the old Community Fund UI

Accumulation of staking rewards in different address

<Pull Request 401>
<Commit 2fb7b47>
This features introduces support for the -stakingaddress launch argument which sets a NavCoin address where the staking rewards are accumulated. It also allows you to specify mappings from one address to another, such that the first address's staking rewards will be deposited in the second address.

stakingaddress can take:

  • one argument (i.e. one NavCoin address), e.g. -stakingaddress=NxxxxMyNavCoinAddressxxxxxxxxxxxxx; or
  • a JSON argument, mapping several staking addresses to corresponding receiving addresses, e.g. -stakingaddress={"NxxxxMyStakingAddress1xxxxxxxxxxxx":"NxxxxMyReceivingAddress1xxxxxxxxxx","NxxxxMyStakingAddress2xxxxxxxxxxxx":"NxxxxMyReceivingAddress2xxxxxxxxxx","NxxxxMyStakingAddress3xxxxxxxxxxxx":"NxxxxMyReceivingAddress3xxxxxxxxxx"}. One staking address in the JSON argument can also be set to all and stakes from any staking address will be sent to the receiving address unless otherwise specified, e.g. -stakingaddress={"all":"NxxxxMyReceivingAddressALLxxxxxxxx",...}

Not compatible with cold staking.

Mnemonic seed phrase support

<Pull Request 400>
<Commit 375c657>
This PR adds a new RPC command to export the existing master private key encoded as a mnemonic:
dumpmnemonic It admits an argument specifying the language.
Support for two new wallet options (-importmnemonic and -mnemoniclanguage) have also been added to allow to create a new wallet from the specified mnemonic.

Fix wrong balance after orphan stakes

<Pull Request 438>
<Commit 4041e3e>
This PR fixes an historical issue which made the wallet show a wrong balance after orphan stakes.

Index cold staking address unspent output by spending address

<Pull Request 434>
<Commit 404d85f>

When running a node with -addressindex=1 executing the RPC command “getaddressutxos” with the spending pubkeyhash of a cold staking address will now return any utxo’s available to spend by that key including those where the pubkeyhash is the spending key of a coldstaking transaction. Previously only regular utxo’s sent directly to that pubkeyhash were returned.

Fix for Payment Request reorganizations

<Pull Request 456>
<Commit 688bf4d>

This PR prevents payment requests with invalid hashes (not set yet or out of the main chain) to count for the already requested balance of a proposal.

NavCoin Core v4.5.2 - Further Community Fund hotfixes and faster blockchain sync

NavCoin v4.5.2 Release Notes

4.5.2 contains a hard fork which explicitly rejects blocks from obsolete versions (4.5.1 and below) signalled by version bit 21. Upgrading to 4.5.2 will avoid a potential network fork (as described below) and ensure you remain on the same blockchain as the rest of the network.

Community Fund Duplicate Payment Hard Fork

<Pull Request 413>
<Commit 7ef765b>
Fixes a bug where the Community Fund payment requests could be accepted by the network multiple times. Enforces version bit 21 for all blocks after blockheight 2882875 (approximately Saturday 16 February @ 1830 GMT) as well as rejecting duplicate payments after the fork height.

Voting Cycle Counter Hotfix

<Pull Request 396>
<Commit a6782c3>
Fixes a bug where the votingCycle field of community fund proposals and payment requests would continue to increment after their terminal state if a user reorgs. Also for proposal/payment requests which change from pending to expired, when the voting cycle is 1 over the cycle limit, staker's votes would continue to be counted even though such proposal/payment request is expired. This bug did not affect network consensus on the status of proposal or payment requests.

Faster Blockchain Sync

<Pull Request 390>
<Commit 1990d92>
Keeps a cache of the community fund votes to avoid an unnecessary recalculation per block which was causing extreme slow synchronization per block. After applying the patch the CountVotes() function is significantly faster.

RPC Tests newly implemented and fixed

The RPC unit test work mainly involved fixing broken RPC tests inherited from Bitcoin as well as creating new ones. This expands our test suite allowing for greater coverage which provides quality checks to the existing codebase and future updates.

NavCoin Core v4.5.1 - Community Fund Hotfixes

4.5.1 contains a hard fork which explicitly rejects blocks from obsolete versions (4.5.0 and below) signalled by version bit 20. Upgrading to 4.5.1 will avoid a potential network fork (as described below) and ensure you remain on the same blockchain as the rest of the network.

Community Fund Hotfixes

Currently if a node reindexes their chainstate db, the node will recalculate the deadline of expired proposals and rewrite such proposals as accepted. A node which reindexes will end up with a different state and potentially reject blocks containing payment requests causing some users to end up on their own fork of the blockchain.

<Pull Request 367>
<Commit c59cd80>

  • This patch ensures the state of previously expired proposals are not rewritten as accepted when a chainstate db is reindexed locally.
  • Ensures proper expiry of proposals after their duration has been exceeded.
  • Adds tests to check the proper expiry of proposals.

<Pull Request 370>
<Commit ddeeed6>

  • Fixes the payout of payment requests when the proposal is already expired. Adds a new state for proposals (PENDING_VOTING_PREQ) to handle expired proposals with pending payment requests.
  • Adds tests to check the correct implementation of this state.

Static Rewards Hotfix

<Pull Request 369>
<Commit 88a9060>

Currently if a block included both a static reward and some transaction(s), the network will reject such blocks since the total amount of fees would be verified incorrectly. This patch fixes the verification and adds tests to check the blocks are correctly accepted.

NavCoin Core v4.5.0 - Static Rewards, Cold Staking and CFund Voting GUI

NavCoin v4.5.0 Release Notes

Cold Staking Protocol Upgrade

<Pull Request 249>
<Commit b1c776c>

This Protocol Upgrade will implement the NPIP_0002 which will introduce a new opcode (OP_COINSTAKE) for the NavCoin scripting language and a new standard transaction type using the new opcode.

The wallet will vote this Protocol Upgrade with YES by default.

  • Adds support for Cold Staking Addresses.
  • Signaled by version bit 3.
  • Adds new rpc command getcoldstakingaddress.
  • Wizard to create Cold Staking Addresses in the Receiving tab of the wallet.
  • Updates several RPC commands to provide results relating to Cold Staking.
  • Adds new RPC tests to test Cold Staking Address creation and use.
  • Added a 'Cold Staking' balance display to the wallet GUI.

Manual testing with a modified wallet client

We also performed a number of tests against the cold staking code using a modified wallet client in an attempt to exploit potential weakness in the code. None of these attempts managed to find an exploit.
Details can be found under release-notes-4.5.0-additional-testing-notes/modified-coldstaking-client-notes-4.5.0.md.

Reject this Protocol Upgrade

To not vote for this Protocol Upgrade, add the following line to your navcoin.conf file:
rejectversionbit=3

Community Fund Voting GUI

  • A GUI interface that can be used to vote for community fund proposals and payment requests.
  • A new notification that will appear when a new community fund proposal or payment request is found on the blockchain.
  • Also added a new warning to the wallet screen to inform users when their wallet is syncing that their balance may not be displaying accurately.

Static Rewards Protocol Upgrade

<Pull Request 328>
<Commit 9601f85>

This Protocol Upgrade will change the NavCoin Staking block reward to a fixed amount of 2 NAV per block. You can read more about this upgrade at its NPIP page, NPIP_0004.

The wallet will vote this Protocol Upgrade with YES by default.

  • Signaled by version bit 15.
  • Adds RPC tests for Static Rewards.

Reject this Protocol Upgrade

To reject this Protocol Upgrade, add the following line to your navcoin.conf file:
rejectversionbit=15.

Dynamic Community Fund Quorum Protocol Upgrade

<Pull Request 328>
<Commit 9601f85>

This Protocol Upgrade would introduce a reduction of the required quorum for the Community Fund in the second half of the votings from 50% to 40%.

The wallet will vote this Protocol Upgrade with NO by default.

  • Signaled by version bit 17.

Accept this Protocol Upgrade

To accept this Protocol Upgrade, add the following line to your navcoin.conf file:
acceptversionbit=17.

Reject specific version bits by default

<Pull Request 336>
<Commit eb6a1a2>

By default the wallet votes yes for the Protocol Upgrades included in the wallet. This change adds a list of version bits which will be voted no by default, while also adding an option to manually vote yes for those bits.

To manually vote yes for a version bit add the following to your navcoin.conf file:
acceptversionbit=17

Block header spam protection

<Pull Request 335>
<Commit 210a22d>

The wallet will now rate-limit the amount of block headers received from a single peer before banning them for misbehaving. This is an anti-spam measure and is customizable via the config file or via launch arguments.

The new launch arguments are:

-headerspamfilter=<0 or 1> - 1 will turn the filter on (it is on by default), and 0 will turn it off.

-headerspamfiltermaxsize=<number> - The number you wish to set as the new max size.

-headerspamfiltermaxavg=<number> - The number you wish to set as the new max average.

Community Fund RPC commands

<Pull Request 334>
<Commit cc8e213>

  • Shows help for proposalvotelist and paymentrequestvotelist.
  • Shows proposals and payment requests in pending state without vote.
  • Categorises cfund rpc commands under own category.
  • Updates RPC tests for these commands.

NavCoin Core v4.4.0 with Community Fund

NavCoin v4.4.0 Release Notes

Community Fund:

The deployment of the Community Fund on mainnet is signaled through Version Bit 6.

It introduces the changes neccesary in the protocol to activate the claims mechanism for the Community Fund with the following parameters:

  • Voting cycle (Vc): 2880 * 7 blocks (Approx 1 week)
  • Min Quorum per period: 50% of a voting cycle
  • Proposals/Payment Requests min age: 50 blocks
  • % of Positive votes to accept a Proposal: 75%
  • % of Negative votes to reject a Proposal: 67.5%
  • % of Positive votes to accept a Payment Request: 50%
  • % of Negative votes to reject a Payment Request: 50%
  • Fee to create a Proposal: 50 NAV
  • Maximum number of full elapsed Voting Cycles for a Proposal: 6 Voting Cycles (1 month and a half)
  • Maximum number of full elapsed Voting Cycles for a Payment Request: 8 Voting Cycles (2 months)

Community Fund Accumulation Spread

The Version Bit 14 will signal for the soft fork to activate NPIP0003.

This is largely a technical improvement which consolidates mined Community Fund contributions to every 500th block instead of every block to reduce blockchain bloat.

You can read more about NPIP0003 on the NPIP GitHub.

Community Fund Contribution Increase

The Version Bit 16 will signal for the soft fork to increase the Community Fund contribution from 0.25 NAV to 0.50 NAV per block.

You can read more about NPIP0005 on the NPIP GitHub.

Reject specific version bits

This release introduces the concept of bit version rejection.

It is designed to make it easier for the network to reject individual soft forks when they are bundled together in one release.

As soft forks come within the software signaling by default only the converse was needed for people to reject soft forks they did not agree with.

A new config concept has been added called rejectversionbit. Users can signal all the soft forks they reject by adding the following to the config.

rejectversionbit=6
rejectversionbit=14
rejectversionbit=16

NavCoin Core v4.3.0 with OpenAlias support

NavCoin v4.3.0 Release Notes

Introduces OpenAlias:

This PR #213 completes the implementation of the OpenAlias protocol into the NavCoin Core client.

OpenAlias is an standard created by the Monero Core project used in the Monero wallet and some other clients like Bitcoin Electrum which allows the wallet to translate email addresses into cryptocurrency addresses using custom TXT entries in the DNS records of a domain.

More details about the specification can be found at www.openalias.org

Part of the code is based in the original Monero implementation. The main differences are:

  • Prefix of the TXT entry is required to be set to oa1:nav
  • The only parsed parameter is recipient_address
  • NavCoin enforces by default the use of DNSSEC

OpenAlias registration

You can now register a OpenAlias address at http://openalias.nav.community/

Wallet support for bootstrapping

A new argument (-bootstrap) is can be passed on initialisation to specify an URL from where a copy of the blockchain in TAR format will be downloaded and extracted in the data folder.

Also adds a GUI submenu entry under FILE which lets you bootstrap using the GUI.

New gui tx status for orphans

In version 4.2.0 the wallet started hiding orphan stakes in the transactions list. This has caused some confusion with users as OS notifications were still showing while the stakes did not appear.

We now clasify orphan transactions with a new "Orphan" status and show them in the transactions list.

Remove BIGNUM use

This PR #214 completely removes the use of the OpenSSL's class BIGNUM, substituting the uses of CBigNum with the class uint256 with extended arithmetic capabilities (arith_uint256). OpenSSL deprecated some BIGNUM functions in version 1.1, making the wallet unable to compile in systems which use the newer version. This patch fixes this issue.

ZeroMQ Windows Patch

Applies https://github.com/bitcoin/bitcoin/pull/8238/files to fix ZeroMQ compatibility with Windows systems.

Staking

Staking can now be toggled "on-the-fly" without restarting the client through the GUI or using the staking RPC command.

Updates secp256k1 Lib

The secp256k1 lib from bitcoin 16.2 release was included into the codebase. While there are a number of improvements, the update was mainly needed due to the better build options for developers and allows newer OS's to build. This reduces the friction in getting setup and working with NavCoin

Transalations

The Wallet GUI is now fully translated to Spanish and Italian.

Other modifications in the NavCoin client:

  • New RPC command resolveopenalias resolves an OpenAlias address to a NavCoin address
  • Added support for sending to OpenAlias addresses in the GUI, when parsing URIs and the RPC commands validateaddress and sendtoaddress
  • New argument -requirednssec to set whether DNSSEC validation is required to resolve openalias addresses (true by default)
  • New argument -mininputvalue to set the minimum value for an output to be considered as a possible coinstake input
    -New argument -banversion to ban nodes depending on their broadcasted version
  • Added support to ban nodes with determined wallet versions using the config parameter banversion
  • Blocks created with the rpc command generate now include a correct timestamp for the coinbase transaction
  • Using the regtest will create a new genesis block on runtime
  • A new testnet has been initiated
  • The development-focused networks regtest and devnet won't require peers for blocks generation
  • Update copyright notice
  • Updates automake to enable dev compilation on New OS's like Ubuntu 18.04
  • Updates Payment request UI to handle new OpenSSL Lib
