looks like they are progressively re-opening wallets. great news. For now there has been no official confirmation of when CRW D/Ws will re-open.

  You can add peers to your crown.conf file, this will speed up the syncing process:

Try these
addnode=108.61.178.55:9340
addnode=95.85.27.206:9340
addnode=85.217.171.132:9340
addnode=54.37.92.209:9340
addnode=217.182.209.190:9340
addnode=80.209.231.248:9340

Or open the debug console(Tools->Debug Console) and type the following:
addnode add

Crown NFT framework testnet is live

Artem has released the NFT testnet 0.13.9.1. Build is available here: https://gitlab.crownplatform.com/crown/crown-core/pipelines/1153 . He will provide information about the APIs next week. There are 2 main commands now nftproto and nftoken

Defunctec has updated the following to 0.13.9.1:

Long term
Crown contributor defunctec has about a million ideas for use-cases for our forthcoming NFT framework. Here he describes one which has reached the prototype stage. Front and back of first prototype https://miro.medium.com/max/976/1*a-RH2ZIXy165Wut7DFdU9Q.png . MMC card for scale.


Reason
Crown will soon introduce NFT to its network and give users the ability to create unique non fungible assets with a few simple actions. To promote these developments the project needs users to build their own use cases to exploit Crown NFT and exhibit the abilities of NFT to the world.


Concept https://miro.medium.com/max/1024/0*oePZnfFJmSc8-9_1.png


https://crwcards.com


A card that represents a users contribution to the project. The card is credit card sized, plastic and contains a NFC chip. The chip will contain unique details of an NFT which is created specifically for the card. Cards will be custom designed and will be held in a card holder which is also custom designed and holds a NFC chip (Yes, even the card holder has an NFT). The card and card holder will represent a pair that are unique and cannot be replicated.


NFT
Two NFT tokens are created under a specific protocol, “CRWCARDS”, for example. The first token represents the card, second the holder. The token which represents the card uses a combination of the cards unique ID number and the users wallet address to generate a sha-256 hash which is used as the “NFTID”, while the holder hash is generated from the cards/wallet hash.
Both NFT’s metadata will be utilized to show Username, date created etc


Tiers
Community members and contributors can apply for a card based on their amount of time and contribution to the project.
Tier 1 — Community member and Crown holder.
Tier 2–1 Year community member, contributor and holder.
Tier 3–2 Year community member, contributor and holder.


Cards and holders
The card will hold information about the NFT, for example the hash of the token. The hash is generated from the cards unique ID.
This means the card can be used as a form of identity for a user and their username that can be confirmed using the chain.
The holder has attached a NFC tag which again contains simple information about the hash and username etc.
Cards and holders will have simple stylish design printed professionally.


Conclusion
The idea involves community engagement and community incentive to become more involved, NFT use case and an insight into how NFT and physical technology like NFC can work hand in hand.
This is just an idea and may or may not be rolled out in 2020.

Crown development meeting minutes 09/01/2020
Just the facts, ma’am

Present: Artem, Ashot, crowncoin-knight, walkjivefly, EdwardMorra

Artem has been debugging and fixing problems in his local sandbox environment. He expects to be ready to move the code into public testnet week commencing Monday 13 January. Between now and then he will build the executables, write some usage instructions and create a video explaining how to use the sandbox environment. This last part is intended for application developers to be able to develop/test their application privately before releasing into the public testnet. He will push his remaining changes to Gitlab this weekend.

The NFT percentage completion numbers are now
* NFT Core — 100%
* NFT Registration — 100%
* NFT Protocols Registration — 99%
* Bitcore NFT support for web-development — 40%

Interested parties can see the current state of the code in the 234-simple-nf-token-protocol-registration-2 branch. https://gitlab.crownplatform.com/crown/crown-core/commits/234-simple-nf-token-protocol-registration-2

Ashot has continued testing and fixing problems in a private 2-node testnet. He pushed a big commit https://gitlab.crownplatform.com/crown/crown-core/commit/f4e9261e2a4d6c095dd756b7aef6c2ca940bac85 a few days ago for an auxPoW problem. Everything is compiling again. He fixed a problem with sync failing after a halvening event. He still has some PoS issues and problems with the build environment to fix. He estimates the code completion at 75% ready for public testnet. Interested parties can see the current state of the code in the bitcoin-merge branch. https://gitlab.crownplatform.com/crown/crown-core/commits/bitcoin-merge

Alexander a.k.a. Edwardmorra will be making some changes to the Gitlab “Continuous Integration, Continuous Delivery” environment, so it will be ready for Ashot’s bitcoin-merge branch testing.

The spanish-speaking CRW community has just launched their own http://crownplatform.es site.

The community has created a shared document with all the use-cases ideas for NFT so far. It can be accessed here: https://docs.google.com/spreadsheets/d/1ejbUm9R0K8Rd-jAjEpx-thi7pdAuaBJ7a-GlZl2w7BI/edit#gid=0

More information on the NFT Framework is now online on a new section of the Crown website: https://www.crownplatform.com/nft-framework/

https://medium.com/crownplatform/calling-community-coders-a1922fa10242

Calling community coders
We have some jobs for you!

If coding’s not your thing please page down to the What’s next section.
Artem and Ashot are working as hard as funding permits on the NFT framework and codebase updates. But there are a bunch of open issues in Gitlab which they may never get the time to look at. Issues which while not even remotely critical could make everyone’s Crown experience just a little bit smoother if they were fixed.

One of the areas most often asked about in Discord or Telegram in terms of improvements and updates is the GUI wallet. And a lot of the low priority open issues are GUI wallet issues. None of them will make the wallet more beautiful or sexy, but they would make it a little more useful.
If the mere prospect of coding anything Qt related gives you the heebie-jeebies fear not, there are other issues which could be tackled in shell script or Node.js or PHP or any other coding environment you’re familiar with.

A few days ago I made a pass through the open issues list and identified a bunch which would be ideal for weekend coding warriors to have a go at. They have all been tagged with a yellow “Community” label and some of them can be seen in the screenshot above.

This post is an open invitation to anyone in the Crown community, or even outside of it, to fire up their favourite IDE, clone the Crown repository and exercise their skills on one or more of the “Community” tagged issues.

You don’t need a Gitlab id to be able to see the repository or clone the project. The issues list is here and you can clone the repo by
git clone https://gitlab.crownplatform.com/crown/crown-core.git

You don’t need to be a top-class developer, anyone with a bit of git experience and the ability to compile the code themself is welcome to participate. There are no bounties available but you could conceivably make an application by a proposal for some Crown reward if you do a particularly good job on one or more issues or tackle one of the harder ones.

This is one of those “ask not what Crown can do for you, rather ask what you can do for Crown” things. Your reward is basically satisfaction at a job well done, a bit of kudos and community appreciation and perhaps knowing you’ve done your bit to protect your investment in Crown.

If you don’t have a Crown Gitlab id you can express interest in working on an issue using the Discord Gitlab updater bot. If you get to the stage of wanting to open a merge request reach out to us in Discord and we’ll sort out a Gitlab id or some other way to test and if successful, merge your code.
Alternatively, many of the open issues were recently copied from Gitlab to Github so if you have a Github account you could fork/clone the repo there and submit a pull request there. If you fix any of the open issues we’ll make sure your code ends up in the right place.

In addition to the primary benefit of getting some issues fixed sooner than they might be otherwise, any increased Gitlab or Github activity reflects well in our FCAS rating. This can help encourage new investors and ultimately drive up the price of CRW.

What’s next?
Looking further ahead we are starting to think about which projects to pursue after the NFT framework and codebase updates.

Some possibilities include:
-NFT trading. Registration is only the first step. NFTs need to be tradeable to maximise their utility.

-On-chain governance. The Dash-inherited governance code is complex and inefficient. On-chain governance would record proposals and votes directly on the blockchain, providing an immutable and deterministic account of the governance system at any point in time.

-Crown Masternode Tool. This is a fork of the Dash Masternode Tool and builds on the Trezor integration which we really hope will finally arrive in Trezor’s January 2020 firmware update. The tool would allow for control of masternodes and systemnodes whose collateral is held in a Trezor hardware wallet. walkjivefly is working on porting the Dash code as and when he gets a chance.

-BTCpay server integration. For Crown to be a usable currency there needs to be an easy way to spend it. BTCpay server is an open-source tool which lets service providers and retailers raise invoices and receive payments in a range of crypto-currencies.

-BlockDX integration. Trading on centralised exchanges is what everyone is used to but is fraught with problems including hacks and exit scams and ever more KYC. BlockDX is a true decentralised exchange with peer-to-peer atomic swap trades.

-QT wallet makeover.

What would you like to see Crown concentrating on once the current projects are delivered? Join us in Discord or Telegram and let us know.

The Cuban community inspired the Czech community to produce a video for the local audience. About 10 contributors participated and this is their view of Crown! We will be pushing it out in our country. Turn on the english subtitles

https://youtu.be/twh94AMgME8

I will write a medium article about this initiative, the idea is that 1. It can inspire local communities to record their own videos and share it in their countries 2. Produce a global video where anybody who wants to participate records a short video on their mobile and sends it to our video guy who will then paste the material together. Lets see if people here would be interested

Seems we're slowly getting there, keep the updates coming.

Thank you for keeping us posted.

Peace!

Crown development meeting minutes 12/12/2019
Just the facts, ma’am

Present: Artem, Ashot, crowncoin-knight, walkjivefly

Artem made several commits this week bringing the NFT percentage completion numbers to

* NFT Core — 100%
* NFT Registration — 100%
* NFT Protocols Registration — 95%
* Bitcore NFT support for web-development — 40%

He will soon be performing local testing in a sandbox environment. He will fix any bugs he finds there and then will be ready to expand testing to the current testnet.

Interested parties can see the current state of the code in Gitlab in the 234-simple-nf-token-protocol-registration-2 branch.
Ashot has been on vacation but has still made progress with the most recent compilation errors he encountered. Currently he’s concentrating on Dash/Crown/BTC incompatibilities. There are also some cosmetic issues with the QT wallet still to iron out but he thinks the code is nearly ready for testnet.

He plans to clone the existing testnet so the code gets properly exercised with PoW blocks, AuxPoW blocks and PoS blocks. He’ll ask pjcltd for some additional nodes for the separate testnet.

Interested parties can see the current state of the code in Gitlab in the bitcoin-merge branch.
Artem and Ashot will both try to submit their proposals this week.
Anyone interested in helping test either testnet can contact Artem or Ashot directly via DM in Discord, or just express a general interest in the relevant #testing-nft or #testing-codebase channel.

https://medium.com/crownplatform/the-crown-community-in-the-czech-republic-meets-again-in-praha-ad45911b9394

The Crown community in the Czech Republic meets again in Praha
A successful regional community meeting supports the direction of Crown towards a milestone NFT usecase. Here is the summary of the event.

Regional meet-ups gaining importance
Eight Crown community members had lunch and beer together in a cool restaurant in Prague 6 on December 7th 2019. Some of them travelled from different parts of the country like Pardubice, České Budějovice and Kutná Hora.
In a decentralised project like Crown, where contributors are dispersed all over the globe, travelling and accommodation costs, make it currently difficult for a global community to get together. That leaves more space for local communities to meet, share ideas and come up with ways to help the project from a regional perspective showing that decentralisation can be locally coordinated and directed towards a shared goal. If regional communities in their respective countries strive for goals which they think are important from their own perspective, the Crown blockchain will grow stronger.


All eyes on “THE NFT USE-CASE”
The Czech guys exchanged views on the current state of the blockchain industry. There was agreement that the entire sector is undergoing a major “cleaning” phase. The shut down of the Cryptobridge exchange was just a recent reminder. The time has come for blockchain projects and crypto currencies to show the world that their breakthrough technologies can be used by a wider audience. Crown should not rely on the recovery of the market, which might or might not come, that is something the community cannot influence. But what we can influence is to help build an application using the awaited Non-Fungible Tokens Framework, which our long-term tech lead Artem is hopefully about to finish within the upcoming Emerald release.
One of the use cases which was very intensively discussed during the meeting was Crown contributor’s Defuctec’s envisioned application aimed at the gaming and streaming industry. The Czech community thinks that a professionally executed application enabling gaming professionals to tokenise in game items, could open the doors for a strong global use case in the heart of an emerging multi billion USD industry. We have agreed, that it would be beneficial to assist Defunctec to secure funding for his idea, so the application can be developed and launched. Crown needs to prove that its NFT direction was the right step. Ideally by launching an NFT application in a sexy sector where fast adoption is likely: in this respect we agree that the streaming industry might meet this criteria. It is to be noted, that the fundraising help does not automatically guarantee that it will be a success.

50k CRW fundraised to support giveaways and other Crown communities
The Czech community agreed to put together a fundraiser, which will be managed by long term Czech contributor Martin @M4RT1N_81. The eight guys who attended the meeting will donate 50k CRW to this address managed by Martin: CRWLHAPGJaqvqZH8DHmuttRymeQnJgAX59Zp. The fund will be used to support any future giveaways, bounties or simply support other communities. This initiative is here to complement and always respect the Superblock, which has unfortunately decreased in value due to the altcoin bear market, and sometimes it is not able to cover all submitted proposals.

Czech language videos in the works
Contributors @Miras and @Holoubek are working on videos about Crown in Czech language. They were inspired by the recent and awesome video of the Cuban community. The format is about introducing Crown to the local audience in Czech language based on the FAQ article put together by the community. Holoubek has experience in making awesome videos and he has even won a local video competition. Stay tuned!

NFT testing help
Another key Czech contributor David_CRW, who has helped a lot with MNPoS testing, offered help to test the latest NFT framework once it is pushed to testnet by Artem. Fingers crossed, testnet will arrive soon.

Latest development update (05/12/2019)

Artem pushed his latest changes to gitlab, current development now at
https://gitlab.crownplatform.com/crown/crown-core/commits/234-simple-nf-token-protocol-registration-2
* NFT Core — 100%
* NFT Registration — 100%
* NFT Protocols Registration — 90%
* Bitcore NFT support for web-development — 40%

Ashot also pushed large amounts of changes, which can be found here
https://gitlab.crownplatform.com/crown/crown-core/commit/d796755e8eaa65aaad2643ff2b29c296265b9fbf

Trezor update
Still no release from Trezor, awaiting new firmware.

Non-Mandatory release
Seed nodes are being updated and a small release will follow. This is a non-mandatory release but is recommended
to improve sync times.

Right, that escalated quickly..

I totally busted the last scam coin that claimed they were in partnership with Sony:

https://bitcointalksearch.org/topic/m.51672520

I'll do the same to your fraudulent claim as well.

Once a scam coin, always a scam coin......

yes it is true that a good sponsor or even several would do Crown environment some good

Well, it starts with all the wonderful things! it is also written on the other source that :

The international firm says "in addition to creating electronic data, starting this system will automatically verify the generation of rights to a written work, which has traditionally proved difficult. In addition, the system is suitable for rights management of various types of digital content, including electronic textbooks and other educational content, music, films, virtual reality content and electronic books. As such, Sony is considering possible uses in a wide range of areas. In addition, blockchain technology could also be used in the health sector in the near future.

So Crown will be propelled into other world spheres! I'm happy for them

Very nice
Thank you crowncoin_knight
Now i have my CROWN CRW masternode on Raspberry Pi


CrownPi - (MNPoS 0.13.4)
Local Masternode hosting for the Crown(CRW) community.

alt text

Introduction
CROWNPI IS NO LONGER RECOMMENDED AS IT DOESN'T PROVIDE INCOMING CONNECTIONS

Hosting from home is risky as your IP address is made public. CrownPi will help you host from home safely using OpenVPN. You must have a NordVPN or AreaVPN account to use CrownPi.

Usage
Raspberry Pi - Raspian Stretch Lite:

sudo wget "https://raw.githubusercontent.com/defunctec/CrownPi/master/crownpiscript.sh" -O install.sh | bash && sudo chmod +x install.sh && sudo ./install.sh
Installation Guide
You must have a new copy of "Raspian Stretch Lite" installed on a 16GB SD Card using win32DiskImager for example.
This script must be run from root.
Enable SSH connections and expand the file system using
sudo raspi-config
Reboot the Pi
sudo reboot now
Now get the local IP address of the PI which starts with 192.168 and can be used for SSH
ifconfig
Once logged in via SSH, use this command to initiate the installation process
sudo wget "https://raw.githubusercontent.com/defunctec/CrownPi/master/crownpiscript.sh" -O install.sh | bash && sudo chmod +x install.sh && sudo ./install.sh
Installation is mostly automated but does require manual input at the end.
Once the script has installed the Crown client and setup the backend the script will ask you which VPN provider you use, NordVPN or VPNArea, please choose and follow the instructions.
Now the VPN is setup, use the crown.conf to enter VPN IP, genkey ect.
sudo nano /root/.crown/crown.conf
Start the Crown Client
sudo crownd
Goto your wallet, where the collateral is held. Edit the node you would like to host. Change the IP address to your new VPN IP address, Click Ok. The node will remain online or drop off. If it drops try "start missing" one more time.
Back to the CrownPi Check the masternode is synced with the CrownPi by typing
sudo crown-cli masternode status
Linux - Ubuntu 19:

sudo wget "https://raw.githubusercontent.com/defunctec/CrownPi/master/crownpiscript.sh" -O install.sh | bash && sudo chmod +x install.sh && sudo ./install.sh
Installation Guide
This guide is based on a new linux VPS.
This script must be run from root.
Enable SSH connections and expand the file system using
Installation is mostly automated but does require manual input. alt text
Once logged in via SSH, use this command to initiate the installation process
sudo wget "https://raw.githubusercontent.com/defunctec/CrownPi/master/crownpiscript.sh" -O install.sh | bash && sudo chmod +x install.sh && sudo ./install.sh
alt text 6. Follow the instructions and enter your VPN details when promted (VPN instructions below) alt text 7. Now the VPN is setup, use the crown.conf to enter VPN IP, genkey ect.

sudo nano /root/.crown/crown.conf
Start the Crown Client
crownd
Goto your wallet, where the collateral is held. Edit the node you would like to host. Change the IP address to your new VPN IP address, Click Ok. The node will remain online or drop off. If it drops try "start missing" one more time.
Back to your VPS Check the masternode is synced with the CrownPi by typing
crown-cli masternode status
Update CrownPi
alt text

Choose between Linux and RPI, then choose update.

./install.sh
NordVPN Commands
Quick guide to using NordVPN with CrownPI

The script will ask you to enter your VPN account details, have these ready to make installation easy.
The command to change your NordVPN login details
nano /etc/openvpn/auth.txt
This command will show a list of regions to choose from
ls -a /etc/openvpn/nordvpn
The next command shows the selected regions servers
ls -a /etc/openvpn/nordvpn/usservers
This is an example of how to correctly choose a server from a region
cp /etc/openvpn/nordvpn/usservers/us998.nordvpn.com.udp.ovpn /etc/openvpn/nordvpn.conf
Now edit the new nordvpn.conf file you made
sed -i -e 's/auth-user-pass/auth-user-pass auth.txt/g' /etc/openvpn/nordvpn.conf
Restart openvpn and check the IP is correct.
/etc/init.d/openvpn restart
And
./whatsmyip.sh
VPNArea
Quick guide to using VPNArea with CrownPI

alt text

VPNArea installation is very simple as the script takes care of most of the work.
When promted, choose which location you would like to use as VPN server
Make sure to enter your correct VPNArea account details
