Nav Coin Details + Nav’s New White Paper: the Cheat Sheet



  • Community Fund Activated

    After many months of planning, developing, testing and retesting the NavCoin Community Fund went through its lock-in period and became fully active on Friday last week.

    Activation means that the world’s first dual-vote Community Fund is open to submissions, proposals can be voted on, and funds released for completed projects.

    Now the Community Fund is ready to go, what will your project be? Here are some resources to help you get started.

    Community Fund tools and resources

    Use these resources to help you develop, submit and deliver a finished project with the NavCoin Community Fund.

    Post an idea and get feedback

    NavCollab website, in the Community Fund channel on Discord, or in the NavCoin subreddit.

    Build a team around your project

    Most successful proposals will require the application of a range of skills, and it’s unlikely that one person will have them all. The NavCoin Collab website is there to help you build a team and fill skill gaps to make your project the best it can be.

    Submit your proposal

    Three easy ways to do this are to:

    Promote your idea in the community

    Get your idea top of mind among voters by promoting it on NavCoin’s key social media channels Discord and Reddit. Also, you can make regular updates to your Space on the Collab website and encourage other community members to follow your project.

    Humans Of NavCoin winner

    Thanks to everyone who tweeted their ideas, but there can be only one winner and it is the team from the Easy Crypto exchange.

    is to expand their service into Australia, making it easier for Australians to buy NAV with AUD. They will now get to work directly with the NavCoin Core team to bring their idea to life.

    NavPi Stakebox update

    For the last two years, the NavPi Stakebox has been the little hero that punches above its weight. It provided the backbone of the NavCoin network, and for only cents worth of energy per year, it did a great job of mining NAV blocks. But a few updates ago the NavPi started to have resource issues. Now that the blockchain has grown to over 2.6 million blocks and with the additional overhead of the Community Fund database, it looks like the NavPi is reaching the limits of its capabilities.

    We managed to extend its lifespan by adding the option to use a USB drive as additional RAM. This fix got most users up and running again, and many people were able to update to NavCoin Core 4.4.0 via the auto-updater mechanism. However since 4.4.0 was released, the Core developers have made several unsuccessful attempts to create a new image for the NavPi with the Community Fund update.

    If your NavPi is running 4.4.0 and you’re mining blocks successfully, then by all means continue using it, but please be aware that the NavCoin Core team will not continue officially supporting the NavPi. We’re sad to see the end of life of this awesome piece of hardware, which has given such great service to the NavCoin network. On the bright side, if you have a NavPi that isn’t able to mine NAV anymore, you don’t need to throw it away! They are still awesome little computers, which you can use for many different things. Head over to the Raspberry Pi website and be inspired by all the cool projects.

    Enter the NavDroid

    We are currently working to release an image for the ODroid XU4 device which is roughly 4x more powerful than the Raspberry Pi. It should be able to mine the NavCoin blockchain for the foreseeable future, while still only drawing 5v of electricity. The plan is for the ODroid XU4 image to come pre-loaded with NavCoin NEXT wallet, which includes advanced features for viewing and voting on Community Fund proposals. The NavDroid will not run the browser-based interface like the NavPi, instead, it will come pre-configured with VNC to use NEXT over a simple remote desktop connection.

    In the longer term, we will plan to release the Kauri Wallet on the NavDroid when that’s ready to ship sometime next year.

    And remember, all these projects are open source, so if anyone else wants to take over the NavPi project and see what they can do to maintain it, you are more than welcome to do so.

    YoBit exchange listing

    NavCoin is looking to be listed on new exchanges. The most recent application for listing was to YoBit. Their NavCoin/BTC trading pair is estimated to go online within the next few weeks.

    NavPay update

    Community member mntyfrsh and members of the Core team have been working to restore service to NavPay. It’s hoped that it will be back online over the next few days.

    4.5.0 core wallet testing

    Matt, Marcus and summer intern Alex have been focussing on writing tests to cover the upcoming 4.5.0 release which is planned to include the introduction of cold staking and static rewards.

    NZ/Japan trade delegation

    Matt, also took time this week to help develop trade relationships between New Zealand and Japan. As the resident Japanese speaker in the building, he met with a delegation of business people from Fukuoka and spoke to them about Encrypt S and the innovative work being done on blockchain technology in Auckland.

    University break internships

    Applications are coming in for the summer internships, and the Developer and Content teams will start interviewing people who’ve made it onto the shortlist soon. The calibre of applicants is very high, so choosing the successful applicants will be difficult. Please email [email protected] if you would like to apply — must be located in Auckland, NZ.

    Maths competition

    NavCoin Core developer @aguycalledalex offered $500 worth of NAV via social media to the first person who could solve a very tricky math problem, and most importantly demonstrate the correct calculations along the way. There are a number of entries and plenty of different interpretations on how to reach the right answer.

    Answers are still in the process of being confirmed, so if you think you’ve got what it takes then try it out! In case you missed it

  • NavPay 4.4.0 released, and proposal voting

    The recent issues with NavPay have been resolved with the updates to the wallet and backend server included in NavPay 4.4.0.

    Since the Community Fund activated on the mainnet, the NavPay wallet had been experiencing issues sending transactions. Now, this is fixed and NavPay is working as it should. For more details on this solution and how to update your NavPay checkout Craig’s NavHub article.

    If you have any questions or need more support, join the community on Discord.

    Get voting!

    Sakdeniz’ NEXT wallet provides NavCoin stakers with an easy way to vote on proposals submitted to the Community Fund. You can see an overview of the wallet and its capabilities at the NEXT wallet page on the Collab website.

    You can also watch this video from the core team’s live stream on how the voting for the proposals works.

    If you’re running a NavPi and having trouble voting, check out this discussion in Reddit for troubleshooting by community members.

    Bootstrapping is enabled again

    Bootstrapping provides you with a much faster way to download the NavCoin blockchain the first time you launch a NavCoin Core or NEXT wallet. The bootstrapping service is provided via AWS and there was a temporary error, which has now been fixed. This Knowledge Base article explains the two methods to bootstrap your wallet.

    NavPi 1.0.9 is available for direct download

    In last week’s Community News we mentioned that due to hardware limitations, the NavPi is approaching the end of its useful life as a staking device for NAV. To ensure that it works until its replacement is ready, there is a stable version of the NavPi available. It contains the 4.3.x wallet, and to start staking you will need to run the built-in updater.

    The Core devs are making progress with the new NavDroid stakebox project we also discussed last week. Look out for more updates on this long-term solution in the future.

    Latest Community Fund proposals

    The Guerrilla Gang made its first appearance on the Collab website with a proposal for a guerrilla advertising campaign to increase awareness of NavCoin in the general community.

    CryptoCandor proposed making a review of the NavCoin Community Fund on her YouTube channel. The goal is to show people how the Fund works and hopefully inspire more people to get involved. Check out her proposal on the Collab website.

    Other new proposals include printing NavCoin stickers to be distributed free to the NavCoin community, Code Signing Certificate for the Core wallet, and a Ledger integration.

    If you haven’t already registered your profile on the Collab website, why not head over and do it now. Then you’ll be able to post your own ideas for discussion and help other community members with their projects.

    How to start your own Community Fund project

    Last week’s Community News contained a lot of useful information on how to get your Community Fund project started. If you missed it, check it out now at NavHub.org.

    Community Fund Boot Camp

    The boot camp will be getting into action soon. The objective is to equip you with know-how and experience to help you develop your own Community Fund project. To register your interest in taking part please complete this form.

  • NavCoin Wants You to Cast Your CFund Votes

    Last month we saw the momentous launch of the NavCoin Community Fund which generates 500k NAV per year to fund community based proposals. Thus far there have been 11 proposals created and a lot of discussion and activity from the NavCoin Community.

    For CFund proposals to pass, there needs to be at least 50% participation in voting by stakers and a 75% acceptance rate within that quorum of voters.

    So far, we’re seeing around 40% participation and we are calling on all stakers to get involved in this process and cast your votes. This is your opportunity to positively influence the NavCoin community in ways which has never before been possible. It’s in your best interest to have your voice heard and cast your votes either way.

    Of the top 20 staking addresses, 10 are not voting either yes or no and we need as many people to participate as possible for this process to work.

    If you recognise any of the addresses below as yours, please check your configuration and make sure you’re voting for the proposals you want.

    How to Vote

    You can view the proposals which are currently being voted on here:

    Nav Explorer - Community Fund - NavCoin
    NavCoin Block Explorer. Tracking Nav blocks, transactions, and addresseswww.navexplorer.com

    Depending on how you’re staking there are a few ways to vote. The universal way is to add the vote directly to your navcoin.conf file.

    to vote yes:

    addproposalvoteyes=<proposal_hash>

    or to vote no:

    addproposalvoteno=<proposal_hash>

    Repeat for each proposal you want to vote for.

    NavCoin Core

    Open the debug window and use the command proposalvote followed by the proposal hash and whether you’re voting yes or no.

    proposalvote <proposal_hash> (yes or no)

    Repeat for each proposal you want to vote for.

    The same command can be issued to navcoin-cli if you’re using the daemon.

    NavPi

    Go to the Control menu at the top then click on the All Commands button. Fill in the form as follows.

    Command: proposalvote
    First Variable: <proposal_hash>
    Second Variable: (yes or no)

    The press the Issue Command button.

    Repeat for each proposal you want to vote for.

    NavCoin NEXT

    There’s a handy youtube video which shows the voting process in the NEXT wallet which you can view here:

    Further Assistance

    We realise this isn’t the easiest process currently and we’re working to make it simpler to engage in the voting process. Over time the community will release more tools and resources to help smooth out this experience. If you are having trouble casting your votes, the best place to connect with the community and seek personal assistance is on Discord or Reddit. We want each and every staker to take this opportunity to participate in this revolutionary form of direct democracy.

  • NavCoin Release  v4.5.0 - 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.
