Crown Core 0.14.0.2 released
Recommended update to stabilize database sync

A new version of Crown Core has been released. It solves inconsistencies between the blocks database and the platform database by levelling out their contents before synchronising to the network.

It is now possible to quickly reindex the NFT database without having to reindex the whole blockchain. To do so you can run platformreindex in the wallet repair GUI. Alternatively, you can run the Crown software with the -platformreindex argument or by adding platformreindex=1 to the crown.conf file.
This update is recommended for users experiencing stuck wallets and for VPS providers that run large amounts of daemons.

Updating Windows and Mac

QT wallets will prompt automatically to download the new version next time they are started. The update procedure is the same as for the previous Emerald update:

    Download the file when prompted.
    Shutdown the wallet.
    Open the downloaded update. This will unzip it into a directory in your downloads folder. Navigate to the Crown-v0.14.0.2-Emerald\bin folder.
    Copy the executables over the old ones.
    Restart the wallet.

Linux

For masternodes, systemnodes and linux wallets the one line script to do all of the above is

sudo curl -s https://gitlab.crownplatform.com/crown/crown-core/raw/master/scripts/crown-server-install.sh | bash -s

You can also download the new version on Github

Dev Flash 21.07.2020
NFT resync functionality coming along. Trezor testers wanted. Crown Bounty program launched. Website drafts evolving.

Ashot
has been working on the nftoken database resync functionality. The release candidate should be ready for public testing by the end of the week. A non-mandatory update will follow shortly. This new version will resync the NFT database to avoid tx-nft db conflicts that led to client instability for some users.

New Crown-Electrum builds
are available for testing. You can get all the information in the Discord channel #bitcore-electrum-testing.

A Crown bounty program
has been launched by several contributors. Read all the details here and engage in open issues to receive rewards!

Bitcore
is progressing slowly, there are no relevant updates on this front.

Website
development for the new community presence has started after intensive feedback rounds on design and structure. You can have a look at the designs and discusssions in Discord.

Stay tuned for more development updates and general news.

Crown bounty program

Incentivising community development contributions

We are pleased to announce the launch of the Crown bounty program. Thanks to the community “sweeper” superblock proposals and some donations, we now have some funds to cover bounties for community-delivered projects.

Several months ago we reviewed the Gitlab open issues and identified some ideal candidates https://gitlab.crownplatform.com/crown/crown-core/-/issues?scope=all&utf8=%E2%9C%93&state=opened&label_name[]=Community for tackling by community members or external coders. We tagged them with the “Community” label and published a Medium article inviting community effort to resolve some of those issues. With no bounties available, unsurprisingly, the response was not great!

The original bounty projects list was a Google docs spreadsheet. Technology progresses and the list will soon be tokenised using the Crown NFT framework. The community fund does not currently have sufficient balance to cover all of the bounty program tasks. We plan to add a “Bounty” label to the Gitlab issues which are active at any one time and also tag those issues with the level of bounty allocated. This will make it easy for anyone to see which issues currently have a bounty attached, and the amount. Simply click here and there’s no need to refer to the spreadsheet.

We will continue to sweep unallocated funds from future superblocks and some community members have indicated a willingness to donate to the fund so we expect to be able to cover all of the bounty tasks in time. If you would like to donate to the community fund please send CRW to CRWW8wDhtZjv8rNfzySvsR2HyGZXRUZwJmZj

If you are interested in working on a bounty task please comment directly in the Gitlab issue, or use the Discord Gitlab updater bot to update the issue, or simply comment in the #bounty-program channel in Discord.

Crown Development Update 07.07.2020
New biweekly format to bring you the latest Crown Platform news

In this edition of the Crown development update we bring you the latest news on the NFT Framework, Bitcore, Crown-Electrum and GitLab CI/CD integration tools. Last week we skipped the development meeting and we have moved it to a biweekly rhythm. It adapts better to our current progress and brings more consistent and digested updates.

NFT Framework

Code lead Ashot has continued debugging logs and has located the main issue we have been experiencing lately, which materialises in some nodes freezing on a certain blockheight before new NFT data is written to the chain. This issue is due to inconsistency between blocks / nftoken databases and can be solved levelling out the amount of information contained in each of them before syncing to the network. In order to improve user experience, Ashot is also going to integrate a new -reindex / -resync option starting on the first NFT block instead of at block 0 so that the process will be much faster and easier to complete by affected users. These fixes are estimated to take 1–2 weeks and will be released in a non-mandatory update.

Crown-Electrum

Community developer Ahmedbodi has been working on a new version of the popular lightweight Electrum client. Testing is advanced and Trezor compatibility has been confirmed, although there are still some bugs to iron out when importing previous CRW Trezor key paths. Once everything is working smoothly, the new version will be officially released.

Bitcore / Insight APIs

Developer Zhanzhenzhen has kept up the work on Bitcore and is now integrating the nfproto APIs. Bitcore will be a key piece to develop on the NFT Framework and will be mainly ued to interact with through the Insight APIs. If you are a developer or an entrepreneur looking to use these featuers, feel free to give feedback on the specs you would like them to include.

GitLab Infrastructure and CI / CDs

The infrastructure team is working on the GitLab environment to integrate Electrum to the official Crown Platform repositories and be able to make these processes easier in future. If you want to help out with Docker or have a high level of Python knowledge, feel free to reach out and give a hand.

A Wordpress plugin to create protocols

Recently, contributor Defunctec released a wordpress plugin to create Crown Platform NF-Protocols. It is available on Github:
defunctec/crown-protocol-generator
A simple Wordpress plugin to create NFT protocols on the Crown blockchain. You need a VPS with (recommended) 2GB RAM, 1…
github.com

NFTRegSign methods

Defuncted has also provided a short and understandable explanation of the NFTRegSign modalities available when creating a new NF-Protocol:

1 (SelfSign)
Imagine being the owner of the protocol but anyone can make a token using this protocol. Someone with enough Crown to sign a NFT transaction can use this protocol to create tokens from their wallet, even though they’re not the protocol owner.

2 (SignByCreator)
Owner makes a protocol and only the owners addresses can be used to create tokens. Unlike “SelfSign” only the owner of the protocol can use addresses associated with the protocol wallet, a user for example cannot use their own addresses.

3 (SignPayer)
This allows an outside address to be used to own a NFT but the NFT must be created via the protocol owners wallet. Eg, You own a website, create a protocol with SignPayer. You can then allow users to enter their address as the NFT owner to create and own tokens using your protocol.

Heartbeat Protocol

The heartbeat NF-Protocol has been created by walkjivefly to keep historical data on Masternode and Systemnode coutns. The tokens issued by this protocol every 6 hours can be called upon to visualize historical data on MN/SN counts and can be used by anyone wanting to leverage this information.

That is all for now on the development front. You are invited to join us on Discord if you want to keep track of everything else that is going on.

Thank you for supporting the Crown Platform project!

Hello. Is there a problem with secure nodes on crown ? Mine are going down every 2 days without having any problems on VPS providers Sad and I don't know what to do anymore as I even re.synced the wallets on the VPS. Any info that anyone can provide me ? Is that burger king deal for real ? :O

Thanks.

You have probably hit the "NFT-glitch" we are experiencing and now fixing https://gitlab.crownplatform.com/crown/crown-core/-/issues/362
If you post the debug.log and we can confirm that is the case.

Does your wallet run 24/7 or do you only run it periodically? On which platform? When was the last wallet restart and did you shut it down cleanly before that?

It would be a good idea to take this opportunity to upgrade your wallet to Artem's hotfix code. The NFT-glitch hotfix builds are at OSX(DMG):

https://gitlab.crownplatform.com/crown/crown-core/-/jobs/7405/artifacts/download
and linux64:
https://gitlab.crownplatform.com/crown/crown-core/-/jobs/7406/artifacts/download
and win64:
https://gitlab.crownplatform.com/crown/crown-core/-/jobs/7407/artifacts/download

Download the appropriate artifact, unzip it, replace the crownd and/or crown-qt by the new ones.

Next you need to straighten out your chain. The quickest way will be with a snapshot of the blocks, chainstate and platform folders from one of your MNs. The alternative is to sync from the latest bootstrap but that'll take longer.

CRW is now on PolisPay
Adding more real-world utility to Crown Platform


PolisPay has released a new version for their popular Desktop application and one of the new highlights is added support for CRW. You can now store, send and receive CRW on the non-custodial PolisPay wallet, as well as use them for a battery of services that are provided in-app such as gift cards, vouchers, phone and card top ups. More upcoming functionalities like the long awaited “Shift” function to swap coins will see the light along with the new mobile versions of the app once Google Play and App Store validate it in the next days.

To help the Crown Platform community onboard PolisPay and learn how to use it, the PolisPay team will be holding a Webinar on Tuesday 19 May at 15:00 UTC. The details will be shared through Twitter, Discord and Telegram, so stay tuned!

You can download the latest PolisPay v8.5.0 desktop application here: https://github.com/grupokindynos/polispay-releases/releases/tag/v8.5.0

Thank you for supporting Crown Platform!

Crown development meeting minutes 04/05/2020
Just the facts, ma’am

Present: crowncoin-knight, Crownfan, pjcltd, walkjivefly

Ashot couldn’t make the meeting but afterwards sent a very short report saying he is still working on the NFT integration and expects it to take about another two weeks. He also provided a link to the essential barebones NFT transaction structure which has now been passed on to the Bitcore and Electrum developers.

There is no progress on the NFT trading design specification documentation.

Community developer Zhen is still working on the Bitcore NFT adaptation. He asked for a brief requirements specification. Our minimum requirements are:
    * correctly decodes NFT transactions
    * it can be used to register both NFT protocols and NF tokens.

    crowncoin-knight will check with Farid of Chronovault what else he requires from it.

Our “on loan” MUE engineer is trying to get ElectrumX to sync and is currently stuck at the first block with NFT transactions. There may be as yet undiscovered NFT-related issues in the Electrum-Crown wallet code as well.
   
Crownfan has been testing PolisPay. The integration is not quite complete yet but hopefully will be released this week.

walkjivefly has added dedicated competition and CRWcard pages to the Platform Monitor, and added geolocation, country totals and map display to the masternode and systemnode pages.

A number of users are experiencing block validation errors on some blocks containing NFT transactions. Their node or wallet ends up banning all of its peers and/or being banned by all of its peers and is then stuck, unable to do anything. This only happens to a small number of users on a small number of blocks. The symptoms are “well known”, the underlying reason is not. Ideally, we need Artem to investigate since Ashot has not had time to do so. Unfortunately, despite there having been at least seven occurrences we know of, most victims have not been uploading their debug.logs as requested so we have very little documentation for Artem/Ashot to work from. The problem does not reproduce at will which makes debugging it much harder.

https://medium.com/crownplatform/crown-development-meeting-minutes-27-04-2020-b630fb2d0a0e

Crown development meeting minutes 27/04/2020
Just the facts, ma’am

Present: ashot, crowncoin-knight, Crownfan, pjcltd, walkjivefly

1. Ashot pushed another MN/SN commit to the Bitcoin codebase update and has started on the NFT integration. In view of the complexity he has revised downwards the completion estimate to 80%. In addition to the NFT integration there are some new RPCs which are stubbed out at present which will need to be implemented.

2. walkjivefly asked Ashot if he could possibly document what he learns about the NFT framework implementation during integration. We are rather short of documentation (as the Bitcore and Electrum community developers have discovered) and despite the extra workload, this would be a good chance to fill a hole in the NFT framework. It could perhaps avoid similar issues with NBitcoin integration further down the line, as required for BTCPay server integration.

3. An agreement has been reached with PolisPay, and funded by a small group of contributors (led by Crownfan), to integrate Crown into their wallet. The Crown node is synced and we are now discussing launch dates.

4. walkjivefly asked what is our official position regarding running masternodes/systemnodes on Windows. Among the recent sync issues have been some on masternodes running on Windows. Despite asking for precise details of the circumstances leading to whatever the issue was, very few users actually provided any or the accompanying debug.log. One user did and it became apparent that their particular sync problem was caused by inconsistent index files after an incomplete shutdown of the QT wallet. While stopping short of saying that doing so is unsupported, we strongly recommend people do NOT attempt to run a masternode or a systemnode on any Windows platform.

5. Artem has not had time to make any progress on the NFT trading design specification documentation. This is a critical requirement for the wider adoption of the NFT framework. A number of developers have considered deploying NFT applications on the Crown framework but told us they have switched to Ethereum instead because of the ability to trade ERC-721 tokens (on the Ethereum blockchain).


6. The community currently needs to fully focus on building NFT use cases aimed at our registration feature only. We believe there might be a lot of space for such use cases in the education, creativity, environment and other mostly non-profit sectors.

7. Community developer Zhen is still working on the Bitcore NFT adaptation. At first the explorer couldn’t download anything. He updated the DNS seeds to make it work again. But then found that after block 2807349 all hashes were wrong because the explorer had followed a fork. He modified the protocol version so the the explorer could get the correct data and it successfully reached block 2817358 (April 3rd). But it stopped downloading later blocks. He found that the next block contains the first NFT transaction. So now he’s implementing NFT features in Bitcore. This problem could have been avoided if he had NFT documentation.


8. Community developer, Sirak, has withdrawn from the Electrum-Crown project. He is too busy to continue with it. pjcltd has enlisted the help of the MUE team to resolve the Electrum issue. The ElectrumX server has heavy CPU requirements (it builds it’s own indexes over the blockchain) which the current VPS struggles to satisfy. The server will be replaced with a higher spec one but this will raise an issue for the infrastructure team regarding provisioning and costs. Meanwhile a MUE engineer is syncing an Electrum server on loaned hardware and is investigating a code problem, possibly caused by NFT transaction incompatibility. If this is the case then it could have been avoided if Sirak had had access to NFT documentation while creating the Electrum-Crown v1.2 release. There may be as yet undiscovered NFT-related issues in the Electrum-Crown wallet code as well.

9. We received an invitation from Portis.io (part of ShapeShift) to be integrated into their non-custodial multi-platform wallet. It wasn’t clear to Crownfan or walkjivefly (who were both contacted) how this would work and requests for additional information have gone unanswered. If there is a community member interested in following up on this, please let us know.

10. There ensued a lengthy discussion about the problems which have followed the NFT framework rollout. A major factor was the lack of project management surrounding it. A small number of dedicated community members pushed through the Emerald release but there was insufficient planning and coordination because we don’t have an actual project/product manager. Combined with the lack of developer documentation this has caused the current Bitcore and Electrum problems. These problems have a detrimental effect on the Crown Platform and increase the costs associated with the projects.

Ultimately the root cause is a lack of funding.

We face the possibility of further problems of this nature with the Bitcoin codebase update. To avoid a repeat performance we need someone to take on a project management role. If there is a community member interested in getting involved in this capacity please get in touch via Discord.

https://medium.com/crownplatform/lets-register-the-most-original-nft-on-the-crown-blockchain-e73581272fd5


Let’s register the most original NFT on the Crown blockchain!
Bounties worth 8500 CRW ($425) waiting for the top 3 winners.

In order to drive visibility and use of the recently released Non-fungible tokens (NFT) Framework which enables public and private participants to tokenise assets on the Crown blockchain, the community has launched a bounty contest with the following details and rules:

Goal: Register the most original NFT on Crown.

NFT Form: Picture, crypto art, video, any ORIGINAL visual or text form.

Requirements:

1.Register your NFT (a simple guide of the steps is below)
2. Share your visual output and NFT txid in Twitter via a Tweet tagging @crownplatform

Voting: The Crown community will vote and select top 3 visuals in the CRW Telegram and Discord channel poll. Votes in both channels will be counted together.

Bounties:
Winning prize: 5k CRW (approx 250 USD)
2nd prize: 2.5k CRW (approx 125 USD)
3rd prize 1k CRW (approx 50 USD)

Contest duration:
* NFTs must be registered and tweeted before 22:00 CEST on Sunday May 10th, 2020.
* Votes must be cast by 22:00 CEST on Sunday May 17th, 2020


For those learning how to use the CRW NFT registration tool, we have put together this short guide. For the competition you need to prepare your content, collect the information needed for the NFT and finally create it.

1. Create your original content.
It’s entirely up to you what you create and how.

2. Digitise it if it’s not already in digital format.
For example, a sketch or painting could be digitised with a scanner or a photo on your mobile phone.

3. Create a sha256 checksum of the digital representation.
Blockchains are not good places to store actual content (a single photo could be several MB, a video hundreds of MB) so we use a sha256 checksum as a short form representation.

Linux users
You can easily create a sha256sum from the command line or perhaps from your file manager. If your content is called /home/alice/art/crown1.tiff you could use the command
sha256sum /home/alice/art/crown1.tiff
to generate the checksum

Mac users
If your content is called /users/bob/crownpic.png you could use the command
shasum -a 256 /users/bob/crownpic.png

Windows users
You may already have a command line or GUI tool installed. If not there are lots of possibilities, some suggestions are here. If your content is called C:\Desktop\photos\competition.mp4 you could use the command
certutil -hashfile C:\Desktop\photos\competition.mp4 SHA256

4. Host the digital representation on any publicly accessible URL.
Use any cloud platform, blog or website you have access to. If you’re using Dropbox, Google Drive, Mega etc., please set the sharing options so that the URL is publicly accessible. Use a URL shortener if you want to pay the smallest possible NFT transaction fee.
Please also ensure the content you upload is the exact one you created the checksum from. It’s a good idea to download the content yourself, calculate the checksum again and compare it with the original value. Some sites, for example imgur.com, alter the content slightly. If the checksum we calculate of the object found at your URL (stored in the metadata field of the NFT) doesn’t match the value in the token id your entry may be invalidated.

5. Prepare to create your NFT.

You will need to provide the following information for your token:

* sha256 checksum as created above. This will be your token id, referred to as <token_id> below.
* Crown address to own the token (any address from your wallet), referred to as <token_address> below.
* URL of the digital representation, referred to as <token_meta> below.

6. Create your competition token
We have created an NFT protocol called nftcomp for competition entries.
You can use the crown-cli tool or the debug console in the GUI wallet to actually register the token using the following steps:
unlock your wallet

{crown-cli} walletpassphrase “your password here” 300
generate a new address if required
{crown-cli} getnewaddress “competition”
register the NFT
{crown-cli} nftoken register nftcomp <token_id> <token_addr> 0 <token_meta>


Successful registration will emit the transaction id you need for your tweet. Registration failure will produce an error message. If the message is
error: {“code”:-32603,”message”:”Signing transaction failed”}

then you forgot to unlock your wallet. If you can’t resolve any other problem please contact us in the #support-wallet channel in Discord.

Don’t forget to tweet your competition entry, for example
@CrownPlatform I just registered #CompetitionEntry #NFT 9bd7bd1b35e66120391959fc7af01aaf3b445703d8660629f310470bd42633a8 representing http://bit.ly/3byUfmm on the $CRW Crown blockchain

You can view competition entries in the dedicated page of the Crown Platform Monitor.
You can view all the other registered protocols and tokens in the monitor too. On the NFTs page you could use the competition protocol name (nftcomp) in the search box or use the “Same protocol” option in the dropdown box on any nftcomp token. Then use the “Txn details” option to see the raw transaction including the metadata which contains the entry URL.

Crown development meeting minutes
Just the facts, ma’am

Present: ashot, crowncoin-knight, pjcltd, walkjivefly

Ashot continues to work on the masternode/systemnode syncing aspects of the codebase update. He pushed one commit last week. The NFT integration looks like being a bigger job than he initially thought. He has updated the FlipsideCrypto chainwalker so that NFT transactions get reported and counted in their metrics. He plans to address the testnet issues once the codebase update is otherwise ready for testing.

Community developer, Zhan, estimates the Bitcore NFT update could be ready in about a month. This will make it easier for Javascript developers, including Chronovault, to build use-cases on the NFT framework.

The Electrum Crown problem has been localised to the Electrumx server which interfaces between the Electrum Crowm wallet and the Crown daemons. We suspect the server doesn’t like or understand our NFT transactions and this stops it from syncing and indexing correctly. This then prevents the wallet from connecting. Community developer, Sirak, is working with Artem to identify and fix the problem. There is no ETA for a fix yet.

It has been suggested that after the Bitcoin codebase update is delivered, we concentrate development on smaller projects which can be completed more quickly and which deliver enhanced usability and functionality to the Crown platform. Examples could be BTCPay server integration, in-wallet proposal creation, Crown Masternode Tool, and on-chain governance (this last one perhaps implemented using NFTs). All present thought this would be a good idea. Some of them are already logged in Gitlab.

If you have any ideas for projects which could be candidates for consideration, please let us know through Discord.

Crown development meeting minutes 06/04/2020
Just the facts, ma’am

Present: artem, ashot, crowncoin-knight, pjcltd, walkjivefly

Testing completed successfully for the NFT registration problem and Artem tagged the patch for release. walkjivefly pushed the release on Saturday. A number of NFT protocols and tokens have now been successfully registered including the first CrownCards.

Artem did not submit a proposal last month nor this and doesn’t expect to have any time for Crown issues beyond emergency hot fixes in the foreseeable future. He is still committed to creating an NFT trading design doc but can’t say when this might happen. He thinks there are two likely ways trading could be implemented. The first would involve a two-party multisig transaction and might be the simplest to implement. The second would involve separate request transactions to advertise an NFT for sale and invite bids, and response transactions. These could be fixed price maker-taker kind of operations or auction style with multiple possible competing bids within a defined limited period of time.

crowncoin-knight asked if someone else could (at least temporarily) takeover continuing development. Artem replied it would be possible for someone with the correct mindset and technical skills. However, doing so without the NFT trading design doc would be difficult and it is unlikely there is anyone in the community with the skills, time and inclination to do so.

Artem will monitor the level of NFT framework adoption as an indicator of how important the community sees the implementation of trading.
There have been a number of reports of sync and “hang” problems since the Emerald release. Most are probably due to forks but some could be related to open testnet issues such as 366, 362, 342 or 341. Artem doesn’t have time to look into them but Ashot said he might be able to. In the meantime we ask anyone having sync/hang problems to provide as much information as possible to help classify and resolve them.

Ashot continues to work on the governance syncing aspects of the codebase update. He estimates the project completion at about 85%. Hopefully this week he will also find time for the FlipsideCrypto chainwalker NFT update, and next week will attempt to merge the NFT framework code into the codebase update. He expects to be ready for testnet soon after that.

Ashot will review the open NFT testnet issues 335 and 333 and decide whether to address them or create a new testnet for the codebase update testing.

The bootstrap instructions have been updated to accommodate NFTs. Testing showed there is no need to change the actual creation process and revealed a potential link to a reduction in bootstrap performance. Issue 367 has been opened. Artem will review the log file.
There has been a report of a potential problem with the Electrum Crown servers. These are not managed by the infrastructure team so defunctec has been asked to contact the community developer to get them upgraded if necessary.

NFTs are unusable in mainnet due to a configuration issue. Artem has created a v0.14.0.1 patch which is undergoing testing. We hope that this will result in a non-mandatory update in the near future.

Ashot missed the meeting but sent a short report: he has fixed the sync issue and is working on masternode/systemnode sync issues. He made three commits in Gitlab since the last meeting. He hasn’t completed the chainwalker update because of the mainnet NFT problem.

NFT testnet is stalled and out of commission until it is rewound to a recent snapshot or issue 335 is resolved.

About 82% of the network updated to the Emerald version before old nodes were disconnected.

Once NFTs are fully operational the bootstrap creation and use will have to include a snapshot of the platform folder.

Crown v0.14 “Emerald” released
NFT Framework will activate on 24/03/2020

Today we are pleased to announce the release of Crown v0.14 “Emerald”. This is a major release and a mandatory upgrade. Crown Emerald includes the NFT Framework code. It is available for download here:

https://www.crownplatform.com/wallet/

ALL nodes and wallets MUST upgrade before 06:00 UTC on 24 March 2020 or they will be cut off from the network. Any node rewards earned, or transactions initiated by previous version clients after that time will NOT be valid on the v0.14 network.
Users have approximately two full weeks, including two weekends to upgrade their nodes and wallets before the cutoff time.
The cutoff will be enforced by a protocol version upgrade which means masternodes and systemnodes must be restarted after upgrading them and the controlling wallet.

Please report bugs through the Help, Guides and Support board at the Crown Forum or through Discord:

https://forum.crownplatform.com/index.php?board=5.0

https://discordapp.com/invite/WXhj2y3

How to upgrade
The next time your current (QT) wallet starts it should prompt you to download the update. The executables for Linux, Mac and Windows are available to download from Github.

Upgrade command for Linux wallets, masternodes and systemnodes:

sudo curl -s https://gitlab.crownplatform.com/crown/crown-core/raw/master/scripts/crown-server-install.sh | bash -s

The basic upgrade procedure is to shutdown your existing version, replace the executable with the new version, and restart. This is true for wallets, masternodes and systemnodes. The exact procedure depends on how you setup the wallet and/or node in the first place. If you use a managed hosting service for your node(s), it is possible they will upgrade them for you, but you will need to upgrade your wallet.
You are recommended to upgrade the controlling wallet before upgrading any nodes in order to minimise the node downtime. The protocol version is changed in this release so you must issue a start command from the upgraded controlling wallet for any masternode or systemnode after upgrading the node.

When a large number of nodes concurrently go offline and come online again it can cause network instability. If you are a node operator or individual with a large number of nodes we ask you to upgrade them sequentially if possible, or in small batches of no more than five at a time, to reduce the risk of destabilising the chain.

What’s new — Crown Core v0.14 “Emerald” features
NFT framework

Crown Core v0.14 “Emerald” is the mainnet release of the non-fungible token (NFT) framework. We have worked long and hard to deliver this unique implementation. Our thanks go to developer Artem for his persistence and dedication, and to the Crown community for continuing to prioritise development funding through very lean times.

There are no changes to the consensus rules, superblock interval or node rewards in this release. The NFT framework provides two new RPCs to register and query NFT protocols and tokens, turning the Crown blockchain into an assetchain.

The NFT framework will be activated at 10:00 UTC on 24 March 2020, shortly after all old version nodes have been disconnected from the network. Until that time the new RPCs are disabled and will report the NFT framework is not yet active.

The new RPCs are:
nftproto which registers and queries NFT protocols.
nftoken which registers and queries individual non-fungible tokens.


More documentation on the NFT Framework is available here:

https://medium.com/crownplatform/crown-platform-nft-framework-18d88f9db76

https://medium.com/crownplatform/crown-platform-nft-framework-part-2-f713fe6cd81c

The framework is nothing without community and 3rd-party developer participation and utilisation. The very first NFT use-case, Crowncards, is ready to roll out the moment the framework comes online.

https://crwcards.com


We described the idea in a recent Medium aticle and the originator, defunctec, has progressed to implementation. He has already taken orders which will be fulfilled as soon as the framework activates.

There are other use-cases in development which we hope will roll out in the days after the framework launch.

Other notable changes
A testnet version of the installation/update script, crown-server-install.sh which simplifies setting up a bare testnet wallet or node.
Some enhancements to the spendfrom.py script which simplify consolidating MN/SN rewards or other cases of multiple transactions sent to a single address.

sandbox.py environment creation and management script for testing independent of the public testnet.
Updated references to Crown Platform home URL wherever it is used in our Gitlab and Github repositories.
Updated mainnet seednodes.

Thank you for your continued support of the Crown Platform project.

Just the facts, ma’am

Present: ashot, crowncoin-knight, Crownfan, walkjivefly

Artem couldn’t make the meeting but hopefully everyone knows by now he made the final merge for Crown Core v0.14 “Emerald” on 9 March and the code was finally released. The NFT framework will activate at 10:00 UTC on 24 March.

Ashot has resumed work on the Bitcoin v0.17 codebase update. He expects to spend about 10 hours per week on the project and estimates it is about 70% complete. He is working on a sync issue and a couple of QT wallet problems. He thinks the basic codebase could be ready for testnet in about 3–4 weeks. Before that can happen though, the NFT framework must be merged in. The NFT framework code is structured in a largely standalone manner. He thinks he’ll need about a week of effort to merge it without calling on Artem for assistance.

Because of the way he has done the codebase integration Crown should, by default, get all of the new features Bitcoin introduced between versions 11 and 17. Some of the highlights include pruning, BIP65, HD wallets, multiple wallets, replace-by-fee transactions, segwit, Bech32 addresses, TOR support. It’s possible some of the new features will prove to be incompatible or otherwise difficult to include but at this point he’s expecting to include all of them.

NFT testnet will remain operational until the NFT framework activation in mainnet on 24 March for anyone who wants to test/experiment, but with a reduced node count. We’ll tear it down and replace it with a new testnet from the genesis block for the codebase testing.

Emerald update progress report
The first of two planned progress reports

Crown v0.14 “Emerald” was released four days ago and the community is making good progress upgrading nodes and wallets.

As of 13:12 UTC on 13 March 2020 the upgraded and total node counts are:

- Masternodes: 261 upgraded of 979 total
- Systemnodes: 505 upgraded of 1027 total


which is fractionally over 38% upgraded.

Remember that you must update your nodes and wallets before 06:00 on 24 March. The NFT framework is scheduled to activate four hours later at 10:00 on 24 March.

Updating nodes and wallets is a very simple task, one which you could do this weekend in less than ten minutes.

Linux users
For each linux node or wallet it’s a simple copy and paste of a one line command:
sudo curl -s https://gitlab.crownplatform.com/crown/crown-core/raw/master/scripts/crown-server-install.sh | bash -s
This will download the update/installation script and run it. The script will download the update, shutdown the wallet or node, unpack the update over the old version and restart the wallet or node.

Windows and Mac users
The process is a manual one but still very simple; you just have to replicate the actions of the linux upgrade script.
Download the Windows 64-bit or MacOS or MacOS DMG update.
Shutdown the wallet.
Open the downloaded update. This will unzip it into a directory in your downloads folder. Navigate to the Crown-v0.14.0.0-Emerald\bin folder.
Copy the executables over the old ones.
Restart the wallet.

In which order should I do things?
We recommend updating your wallet before updating any nodes. After updating any nodes you need to issue a new start command from the controlling wallet.

Artem couldn’t make the meeting.

Ashot couldn’t make the meeting but sent a report: he has identified the cause of the sync problem mentioned last week and is working on the fix.

NFT testnet is still running and will remain operational until the NFT activation in mainnet on 24 March, for anyone who wants to test/experiment, but with a reduced node count. We expect to tear it down and replace it with a new testnet from the genesis block for the codebase testing. Anyone wishing to test NFT applications outside of mainnet after the activation can use a sandbox environment.

The Emerald update is going well, over 48% of the network has upgraded. There have been a couple of reported sync problems but they’re not related to the actual update.

The sync problems (with new nodes) may have been due to DNS seeder issues. The infra team are investigating and will make sure the seednodes are up.

Emerald update progress report
The second of two planned progress reports

Crown v0.14 “Emerald” was released eleven days ago. The community has made further good progress upgrading nodes and wallets since the first report last week.

As of 12:48 UTC on 20 March 2020 the upgraded and total node counts are:

Masternodes: 486 upgraded of 869 total
Systemnodes: 702 upgraded of 986 total


which is fractionally over 64% upgraded.

The figures for 13 March were:

Masternodes: 261 upgraded of 979 total
Systemnodes: 405 upgraded of 1027 total

That’s an extra 522 nodes updated and total node count reduction of 151 nodes. Thank you to the hosting operators and individual community members who have already upgraded.

We expect most of the “missing” nodes to come back online as v0.14 Emerald nodes. Until they do masternodes are earning a roughly 19% ROI and systemnodes a whopping 50% ROI (excluding server expenses).

Remember that you must update your nodes and wallets before 06:00 on Tuesday 24 March. Any node rewards earned, or transactions initiated by previous version clients after that time will NOT be valid on the v0.14 network.

The NFT framework is scheduled to activate at 10:00 on Tuesday 24 March.

Updating nodes and wallets is a very simple task, one which you could do this weekend in less than ten minutes.

Linux users
For each linux node or wallet it’s a simple copy and paste of a one line command:

Open the downloaded update. This will unzip it into a directory in your downloads folder. Navigate to the Crown-v0.14.0.0-Emerald\bin folder.
Copy the executables over the old ones.
Restart the wallet.

In which order should I do things?
We recommend updating your wallet before updating any nodes. After updating any nodes you need to issue a new start command from the controlling wallet.

Something to watch out for
Sometimes an updated node can appear stubborn about not wanting to restart properly. The status reported by your wallet may be different from what the node thinks about it’s own status. If you send a start-alias command from an updated, synced wallet to an updated, synced node, and that node does not report it’s status as “Masternode successfully started” then wait two hours and re-try the start-alias command.
This behaviour is not unique to Crown, but is common across all masternode coins. We are aware of three cases since the Emerald rollout started. All three were resolved as described above.

Just the fact, ma’am

Present: ashot, Crownfan, crowncoin-knight, walkjivefly

Artem couldn’t make the meeting. With Emerald released and programmed to disconnect old nodes and activate the NFT framework tomorrow, he’s had no Crown work to do for the last couple of weeks. He’ll be on hand tomorrow in the event of any unforeseen problems. Hopefully at the next or following meeting he will present a design doc and time estimate for NFT trading functionality.

Ashot has been working on the sync issue with PoS blocks. He still has some UI, MN and SN items to address and estimates he is about 80% ready for testnet. He has also been working on modifying the FlipsideCrypto chainwalker so it can understand NFT transactions ahead of the framework activation tomorrow.

NFT testnet is still running and will remain operational after NFT activation in mainnet tomorrow. Ashot has decided it will be useful to use it for the codebase update so it gets exercised on all the block creation methods we have used.

The Emerald update is going well, over 75% of the network has upgraded. The old node cutoff and NFT activation are programmed in and will happen automatically tomorrow at 06:00 UTC and 10:00 UTC respectively. Everyone who has updated their nodes can look forward to a significant reward boost until the laggards realise they are on the wrong chain and update. Any rewards earned, or transactions initiated by 0.13.4 nodes after 06:00 tomorrow, will NOT be valid on the Emerald chain.

The NFT marketing campaign will kick into high gear tomorrow. The press release is already with the news amplifier service and will start appearing in downstream services in the next couple of days.

Crown Platform activates “Emerald” NFT’s
In-house NFT Framework to tokenise assets on the Crown blockchain

- Crown Core v0.14 “Emerald” brings the NFT Framework to mainnet.
- The NFT Framework enables decentralised, non-fungible token issuance for tokenisation of assets on the Crown blockchain.
- Artem Brazhnikov, Crown Platform technology lead, author of the in-house NFT innovation.
- The decentralised registry functionality activates on March 24.


Crown Platform, a community driven cryptocurrency (CRW) and application platform, has released the Crown Core v0.14 “Emerald” NFT Framework, its latest technological in-house innovation. The Crown Platform NFT Framework enables the tokenisation of assets on the Crown blockchain by the issuance of protocols and tokens. With this release, authored by technology lead Artem Brazhnikov, Crown Platform extends its functionality to serve as a decentralised and immutable registry: an asset-chain.

Issue protocols and tokens on the Crown Platform starting March 24.

“The NFT Framework is a way to tokenise assets without writing any asset-specific code.”

Starting March 24, individuals, businesses and institutions can become issuers of unique protocols and tokens, specifying their rules and participating in the creation of a decentralised on-chain registry linked to the CRW public-key cryptography and powered by a highly secure Masternode Proof of Stake consensus mechanism. The Crown Platform development has been focused on the usability of the framework. That is why no additional coding language is needed to program the tokens, unlike Ethereum’s ‘Solidity’ approach. As Artem Brazhnikov puts it, “the NFT Framework is a way to tokenise assets without writing any asset-specific code”.

NFT structure: Create a protocol and define its rules. Now you can issues tokens within that protocol!
The NFT Framework represents a central part of the always evolving Crown Platform ecosystem. NFT applications range from registry of digital and physical assets to the extension of Crown’s governance and consensus structures through additional possibilities of registry, authentication and documenting. This development milestone is a big step forward for the Crown Platform and it’s enthusiastic community, and there are more to follow. Implementing instant NFT transactions for non-fungible asset exchange and trading are among the top development priorities, together with the soon to be released Bitcoin v0.17 codebase update.

Crown stakeholders have been working on this pioneering cryptocurrency project for years, allowing Crown Platform to evolve through its Decentralized Governance and Proposal System, an algorithmic voting and funding mechanism that allows the Crown Platform project to self-sustain its path towards further technological and social innovation. By doing so, Crown Platform is creating an alternative, decentralised economy based on it’s native fair-launch coin, CRW.

The Crown Platform community is committed to enabling an open, decentralised, and community governed infrastructure, supporting functionalities that leverage the potentials of blockchain technology while remaining truthful to decentralisation and permission-less interaction in a cryptographically secure and incentivised peer-to-peer network. New users are joining Crown Platform everyday, adding new ideas to build on it’s technology.
This press release has gone into distribution using the Cointraffic PR amplifier service starting March 24.

These are some of the websites the PR will be published on:
https://cryptopotato.com/
https://walletinvestor.com

Present: artem, ashot, crowncoin-knight, Crownfan, walkjivefly

Artem pushed fixes for the testnet NFT validation issues.

Ashot did not give his report because we took items out of order but said he would be able to help with the Emerald release cutover if necessary.

Testnet stability has been good for the last three days. We have 34 nodes and a few wallets all on the same chain. The NFT validation issues are resolved. Based on this we think it is safe to proceed with the v0.14.0 “Emerald” release. There was a misunderstanding last week about the mechanics of the protocol enforcing cutover and NFT activation. Artem will not be available on 23 March so the timetable changed slightly. The plan is:

* Release on or by 9 March
* Protocol enforcing and old node disconnection at 06:00 UTC on Tuesday 24 March
* NFT framework activation at 10:00 UTC on Tuesday 24 March.


The marketing team are ready to launch the campaign.

Community developer, Sirak, has completed the work on Crown Electrum and it is working perfectly with Trezor Model T. We expect it to also work with Trezor One when/if Trezor release a firmware update for it. They usually issues releases on the first Wednesday of the month so there is a possibility of it happening today. Crownfan asked ashot to assist with getting the Crown Electrum executables into the Github/Gitlab repos since Sirak doesn’t have the authority to do so. We will publish a Medium article when the “end-user” executables are ready for download. Until then, adventurous souls/experienced command line warriors can clone the Gitlab or Github repos and build the code for themselves.

Crown development meeting minutes 24/02/2020
Just the facts, ma’am

Present: Alexander, artem, Crownfan, crowncoin-knight, pjcltd, walkjivefly

Artem spent the weekend working on the registration issues opened by walkjivefly. Since he couldn’t connect to testnet (for reasons unknown) he worked in his sandbox. He has reproduced some of the issues, identified the problems and will try to push a new build tonight.
He thinks the testnet instability problems are probably not related to the NFT framework.

Ashot was not present but sent a message via crowncoin-knight saying he would soon resume work on the codebase update.

* Testnet stability has improved since the last rewind and blocking of “unknown” nodes. Defunctec did some analysis which suggests the much increased superblock frequency in testnet could be a contributory factor to the instability, probably more so than the old version nodes which connect sometimes.

* walkjivefly asked if Artem could push a new build which reduces the testnet superblock frequency to the same as mainnet and refuses connections from old protocol nodes. If such a build proved more stable it would give us confidence that Emerald should not suffer the instability problems seen in testnet.

* He also asked if having chosen an activation block for disconnecting old nodes, mainnet could refuse NFT transactions before that block is reached in order to prevent any invalid transactions sneaking into the chain and perhaps causing issues later. Artem prefers to enable the NFT functionality with a spork because a skilled attacker could fake an NFT transaction without using the nftproto or nftoken RPCs.

* pjcltd has a pool of 20 additional virtual machines ready to start as soon as he’s given the build number to use. This will increase the size from about a dozen nodes to just over 30 and should help improve the stability for the remainder of the testing period.

* Alexander and pjcltd are working on including new testnet DNS seednodes in the next release which will further improve the testnet stability and ease of adding new nodes.

* We may create a completely new testnet (with a whole new datadir) for the codebase update.

walkjivefly asked how confident are we of being technically ready for a very provisional timetable of Emerald release on 2 March, NFT activation and protocol enforcing on 16 March. Artem wants to address all of the known NFT issues before release. Given our resource availability situation a more achievable plan is to aim for a 9 March release date and protocol enforcing on 23 March.

Crownfan explained the Emerald marketing campaign is in development and close to being ready. It will be deployed in stages with each one building on the previous. We need to be certain that the code is ready to go at the advertised block height/date before launching the campaign. Once launched much of the message will take on a life of it’s own due to organic/viral growth and cannot be altered or stopped. If the cutover doesn’t happen on the announced date the campaign will be much less effective or even wasted.

We have put out feelers to exchange partners about the update. We need to give them two weeks notice of the protocol enforcing cutover point and provide the repository link to the release candidate code in Gitlab.

After lengthy discussion of all the factors we have settled on a provisional timetable of Emerald mainnet release on or around 9 March, protocol enforcing and NFT functionality on 23 March. This gives us a bit over a week to resolve the necessary stability and NFT issues, two full weekends for people to upgrade their nodes, sufficient notice period for our exchange partners, and a short window for contributors to rollout the first NFT use-cases, including Crowncards, before Coinfest 2020 in Manchester on 3–5 April.

Crown development meeting minutes 17/02/2020
Just the facts, ma’am

Present: artem, crowncoin-knight, pjcltd, walkjivefly

There was no development progress meeting last week. Artem is too busy during the day now so we have moved the meeting to Monday evenings.

Does the Emerald release absolutely have to be a hard fork release? If so, how will it be activated?
Artem thinks we should upgrade the protocol version for the new release and cut off old version nodes/wallets after a couple of weeks. Given the recent problems with testnet instability walkjivefly agreed. Theoretically Jade clients should ignore NFT transactions and be able to mint blocks containing them, but the presence of non v0.13.9.3 nodes on testnet is suspected to have contributed to its instability.

A very provisional timetable for the Emerald release is mainnet release around 2 March, protocol enforcing from two weeks later. This will mean the whole network is NFT capable two or three weeks before Coinfest UK (3–5 April) and we will be able to demonstrate NFT applications at the event. This is subject to

* Artem having time to review and fix the latest NFT protocol validation bugs and testnet remaining stable after he releases a new build to test a protocol version change and enforcing.
* No insurmountable obstacles from our exchange partners if presented with Emerald being a hard fork release.

The state of testing completeness
As reported previously there has been very little community participation in NFT framework testing. There have been some practical difficulties for anyone who would like to participate. We had to rewind the chain on 9/10 February to the 16 January snapshot to resolve some incompatibilities introduced by the enhancement requests in v0.13.9.3.

walkjivefly conducted some basic framework command validation last week and encountered a number of problems for which he opened new issues. These were intentional attempts to break things, not expected to occur under “normal” circumstances. Other testing that we’re aware of has amounted to little more than creating some protocols and tokens. There hasn’t been any application-level testing in the public testnet. If anyone has been conducting sandbox testing please let us know.

At the end of last week testnet fractured into at least three chains and proved difficult and time-consuming (ie: all weekend) to restore.
Review of open testnet issues. How/when will the remaining open issues be addressed? Which ones MUST be fixed before release, which ones can be deferred?

Artem will review the protocol and token validation issues. These are fundamental things which MUST be addressed. Testnet stability/locking issues will be monitored after Artem pushes a protocol version bump. To help with this pjcltd will add a bunch of additional testnet nodes on the servers he manages. In this way we should be able to extend testnet from around a dozen nodes to between about 30 and 40.
Some issues will be deferred until after the Emerald release. At that point we will probably completely re-initialise testnet and then see which are still extant.

Probability of getting the bitcore API completed in time for inclusion in the release?
Artem doesn’t have the bandwidth to do this, and definitely not before our target release date. He estimates there may be a month of full time work required. He has discussed this with defunctec and crowncoin-knight who will see if they can find an external developer to complete it. The chances of getting it done in time for the Chronovault use-case to be ready before Coinfest are slim but not entirely impossible.

State of readiness for the marketing campaign?
crowncoin-knight reported the marketing team have secured the funding required for the marketing plan. Materials are being prepared and should be ready for a March campaign launch, in parallel with the Emerald code release.

Crown non-development meeting minutes 06/02/2020
Keeping the community informed

Present: crowncoin-knight, pjcltd, walkjivefly

There was no development progress meeting yesterday. Instead a few contributors had a short discussion about NFT framework testing, strategy regarding the forthcoming “Emerald” release, and the marketing plan for it.

The level of NFT framework testing/experimentation appears to be very low with no testnet activity except from walkjivefly and defunctec. There has been no feedback from any other contributors in Discord or Gitlab. We can only hope the reasons are

* other community members, 3rd-party developers and experimenters are using sandbox environments instead, and
* Artem’s code is rock solid with none of them hitting any issues.

The marketing team lead by Crownfan and KalayaanCrypto have created a comprehensive marketing plan (see below) for the Emerald release. They require that the complete funding for this plan be secured upfront so that there is no chance of not being able to complete it. If funding is not secured then the campaign will not be launched. We are expecting a Medium article from Crownfan this weekend explaining the matter in greater detail.

Crown Platform has signed up as a sponsor of the Coinfest 2020 (see below) meeting in Manchester on the 3rd to 5th of April 2020. We will have a several person presence there for the full three days of the event and expect to be able to demonstrate the NFT framework through defunctec’s Crown Cards application and hopefully other 3rd-party use-cases.

We discussed the timing of the v0.14.0 “Emerald” mainnet release. We are keen to launch it around the start of March with the marketing campaign kicking off at the same time. However, there is an argument for delaying the launch of the marketing campaign, and even the Emerald release, until Coinfest. The decision will be made soon (probably within the next week) and will be influenced by the level and outcome of NFT framework testing and the success or otherwise of raising the funds for the marketing campaign.
