https://medium.com/crownplatform/crown-v0-14-emerald-released-f710c0206555Crown v0.14 “Emerald” releasedNFT Framework will activate on 24/03/2020Today 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=5.0https://discordapp.com/invite/WXhj2y3How to upgradeThe 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 frameworkCrown 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-18d88f9db76https://medium.com/crownplatform/crown-platform-nft-framework-part-2-f713fe6cd81cThe 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.comWe 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 changesA 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.

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.
https://medium.com/crownplatform/emerald-update-progress-report-693eba88daf3Emerald update progress reportThe first of two planned progress reportsCrown 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 totalwhich 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 usersFor 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 usersThe 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.
https://medium.com/crownplatform/emerald-update-progress-report-6de3f0060b00Emerald update progress reportThe second of two planned progress reportsCrown 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 totalwhich 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.

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 forSometimes 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.

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.
https://medium.com/crownplatform/crown-emerald-press-release-d79436340a2eCrown Platform activates “Emerald” NFT’sIn-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.
