Crown development meeting minutes 24/10/2019

Status: Approved
Present: Artem, Ashot, walkjivefly, crowncoin-knight

- Artem is happy to continue hosting the weekly development meetings.

- Artem has a contract with someone else but will continue developing the NFT framework on a best-effort basis. He will have very little spare time until 6 November but thinks he’ll be able to dedicate 10 hours per week to Crown thereafter. He has committed to delivering the elements discussed in Discord which currently have approximately the following levels of completion:

* NFT Core — 100%
* NFT Registration — 100%
* NFT Protocols Registration — 70%
* Bitcore NFT support for web-development — 40%


We are not announcing a target NFT testnet release date because he is unable to guarantee how much time he will have available for Crown.
Artem will make a development proposal this month at the discretion of the community. If there is nothing the community thinks is more important he will submit for half of the 50% development portion of the superblock.

Ashot has another contract and is able to spend about 10 hours a week on Crown. He has the new codebase compiled and is fixing initial bugs. The QT wallet has been problematic but it is also running. The wallet is not yet syncing the PoW section of the Crown blockchain. When it syncs past the PoS changeover Ashot considers it will be ready for testnet deployment and we’ll invite the community to join in the testing effort.
There is no target codebase testnet release date yet.

Ashot will make a development proposal for half of the 50% development portion of the superblock.

Artem has pushed all outstanding private commits to Gitlab. The code is available for inspection in the https://gitlab.crownplatform.com/crown/crown-core/tree/234-simple-nf-token-protocol-registration-2 and https://gitlab.crownplatform.com/crown/crown-core/tree/develop-platform branches.
Ashot will push all outstanding private commits to Gitlab https://gitlab.crownplatform.com/crown/crown-core/tree/bitcoin-merge branch by the end of this week.

The next release/deliverable may be NFT framework, it may be the codebase update. We’re not making a prediction either way, nor when, at this time because neither Artem or Ashot can guarantee their availability.

Trezor Model T firmware claims to include Crown support but in tests Electrum Crown is unable to connect to the device. The Trezor One firmware doesn’t yet include Crown support. That may be released on 6 November but we have no way of knowing Trezor’s plans in that regard. Our Electrum Crown developer, Sirak, does not have a Model T, only a Model One so is unable to investigate the connection problem at this time.

Community members defunctec and walkjivefly have forked the Dash Masternode Tool and are investigating adapting it for use with Crown and Trezor. It appears there will be quite a lot of work required and probably the efforts of an external developer, possibly Sirak. We’ll know more once Electrum Crown is able to talk to at least one Trezor model.

CROWN a global solution for creating private blockchains for your various transaction models, for the exchange of your non-fungible goods and for the application of your smart contracts all this on CROWN's stable and secure network.

CROWN in progress:

✅ Implementation and imminent deployment of the CROWN Platform which is the ecosystem to accelerate the transition from decentralized systems to NFT to enable the management and production of governance and scalable analysis for all your customized projects to one or more chains hosted directly within the platform network.

✅ Establishment of voting systems without individual control to allocate funds, development, marketing and infrastructure budgets (allocated assets).

✅ CROWN describes itself as an open network for Web 3.0 applications and custom decentralized solutions, with a range of tools specifically designed to facilitate and make accessible the process of developing and executing dApps based on CROWN block chains designed to meet the needs of developers and companies who want to take advantage of the properties of blockchain systems - including security, auditability, verifiability and untrusted transaction execution and business logic.

CROWN next level:  

📢  Publication of the CROWN programming language for the programming logic.

⛏️ Implementation of IDE infrastructures for sandbox development, tools, SDK kits, libraries, frameworks and protocols for simple and practical integrations.

🔥 Implementation of back-end services. First implementation of intelligent contracts operating functions.

 Productions of new compositions of the main layers:

⚡ Infrastructure layer: base for private key management, IDE for sandbox development, CROWN language for intelligent contract programming and other tools for application development, NFT 2.0 API, libraries, games, tools and frameworks.

🚀 Protocol layer: MNPOS X and NFT 2.0 extension for fractional models.

🌎 Application layer: basic open-source applications (decentralized exchange, mobile applications and voting) and various dApps applications running on the network on dApps.

🌙 Formatting of projection controls, interoperability of concrete solutions and optimal security within its decentralized network. Return to operation and implementation of privacy (Filters) and equivalent UTXO (MNPOS X).  

🛸 Interactive marketing, data analysis tools in the global chain.

🌞 Technical and curative audit to analyze and strengthen the scalability of processes through the measurement of relevance and consistency, feasibility and efficiency standards.

✨ CROWN V3

Much more functionality and surprise to come 💎


Great perspective

To answer the Holoubek question on Discord can we add that a Crown MNPOS node can run on Raspberry PI 3 B+ is powered by 5V / 2.5A, but the consumption is estimated on average at ~500mA so very far from the consumption of Proof Of Work protocol from Bitcoin. Crown is very " cost-effective " in terms of resource exploitation and on the environmental footprint and carbon emission, it is quite possible to group in a cluster. It is possible to operate from an environment or from servers hosting websites for example for maximum fluidity and the operation of a "wallet" under windows 10 for a node requires only 640mHz and 700mo of ram memory, and 11GB storage to host the Crown blockchain. Namely also that it is also possible to run several CRW nodes in an emulated environment ;-) the strength lies in dedicated IP addressing, the network velocity is linked to the protocol and the number of nodes, to date there are several hundred active nodes that are a catalyst for the security of the entire network.

Crown's only weakness to date is a limited number of operating developers which penalizes "the speed" of deliveries but the evolution is well present since 2014, that said at Crown there are ideas that are realized through the admirable work of the developers provide and the contributors who work in the shadows and light with or without the slamming of asses.

Crown remains continuously open, if you want to be part of the building the door is wide open, no matter your age, your nationality, your horizons.

It has become clear that chain companies cannot thrive in this sector without the help of regulators and policy makers. thus forming an appropriate framework. Regulation is useful for adoption of It's a fast financial technology, as the absence of regulation will make it difficult to recognize encryption technology. What about CROWN's position in the sector? Is there a label?

Trezor integration is a great step forward for Crown. With the address format changed, is it possible to apply for Ledger integration?
Thank you.

Perhaps one day Crown will launch a new service based on the blockchain supply chain, integrating artificial intelligence and Internet of Things technology as a supply chain service based on its blockchain platform via its open source software allowing developers and third-party applications to leverage traditional enterprise data systems that can be integrated into a distributed general ledger. The new service can be cloud-based, combined with existing management system or order services, will integrate technologies such as blockchain and artificial intelligence to enable real-time visualization of order shipments for e-commerce, for example, alerts and optimization recommendations.

By using an open CROWN API, the supply chain suite allows distributors, manufacturers and retailers to integrate, along with their suppliers' data and networks, into the blockchain to track products and components. Data that can be integrated include the IoT sensor system for real-time cargo location.

It is a suggestion of accompaniment, Blockchain will become the "identity card" for tangible and intangible products.



Hey team Roll Eyes I wonder if it will be possible in the future on CROWN Plateform function to set up privacy protection. In the private binary transaction channel, the user transfers the account to the confidentiality agreement via the public address, the specified number of account assets in the public address disappears and generates the UTXO equivalent as an entry, the confidentiality agreement is verified and the balance is generated in the specific public address account. complete the confidentiality transaction. With the binary element privacy protection function, it is possible to achieve non-connectability and non-traceability, and the privacy channels of both parties to the transaction can be established to protect the privacy information of both parties.

It was noted that the binary confidentiality protection function can be used in management scenarios such as master data and chain confidentiality protection, employee equity incentives and transaction dividends..்

Interesting idea, might be a good idea to add it / pin it in our gitlab for future reference, maybe some dev can make it happen.

Hey thanks for your feedback Smiley

If I understand correctly, CROWN is engaged in a post-production test process where the result may be incomplete due to lack of funding?

Test is very conclusive

Questions:

- Where to see explore public to see NFT?
- How to post pictures, videos, mp3 in metadata?
- How to censor prohibited, illegal texts or metadata images?
- Is there an interface to sell, exchange or buy non-fungible NFTs?
- Is multilingual translation planned?
- Qr code shortcut link is planned?
- Non-Latin character (Chinese-Russian, Indian, Korean........) are they compatible?

Where to see explore public to see NFT?
http://defunctextest2.com/nftlist.php
- How to post pictures, videos, mp3 in metadata?
Metadata is only made for text. Post a link to the image in metadata.
- How to censor prohibited, illegal texts or metadata images? There are no images or videos hosted on the bloclchain, only tokenised representation of it (Hash "nfTokenId" and link in metadata).
- Is there an interface to sell, exchange or buy non-fungible NFTs?
Trading of NFT tokens are planned for the release after Emerald as well as Bitcoin core updates to (0.17).
- Is multilingual translation planned?
Not sure about this.
- Qr code shortcut link is planned?
Couldn't this be built by the community? Block explorers etc
- Non-Latin character (Chinese-Russian, Indian, Korean........) are they compatible?
I doubt this but should be considered if funding allows.

Development update October 2019
Almost ready for release


Despite the constraints on their time resulting from superblock budgetary limitations, both Artem and Ashot are making solid progress with their projects. It looks like they’ll be ready to advance to their next stages at about the same time. In this update we talk about the active projects, the forthcoming Emerald release and tease you with possibilities for the subsequent release.

NFT framework
Artem is still working to finish the mempool transactions and NFT protocol registration functionality. These have proved trickier than anticipated but he thinks they’ll be done and the Emerald release (v0.14) ready for testing by the end of next week. So we’re on track for mainnet release early in November.

We have some volunteers lined up to help with the testing but it would be helpful to have a few more. If you are also keen to help then a good preparatory task would be to get set up on testnet. Then, as soon as we push the release you’ll be able to upgrade and get stuck in. The more people we have testing the release the shorter the test window can be and the sooner we can push the mainnet release.

We’ll publish an article in the next couple of days explaining how to get involved if you’ve never experimented with testnet.

Codebase update

Ashot is putting the finishing touches to the QT wallet code. This has proved a bigger task than anticipated but it is the last section of the Bitcoin v0.17 codebase to be integrated. He is hopeful that by the end of next week he’ll be ready for the first attempt at firing up the merged code. He’s expecting it to not work perfectly first go and to hit some bugs. Probably after a couple of weeks it will be ready for more widespread testing.


Trezor — the proof is in the pudding
Due to an unfortunate oversight, Crown is not yet usable with the Trezor hardware wallets. We have submitted another merge request, which has already been accepted. We are hopeful that Trezor firmware versions 2.1.7 for Model T, and 1.8.4 for One, will finally work with Crown. It’s not possible to test in advance of the releases so we won’t know for certain until the firmwares are available in the wild.


So what will be in the Emerald release?


Crown v0.14 “Emerald” will include:

NFT core functionality
NFT registration
NFT protocols registration
Bitcore NFT support for web-development


These components will provide developers and web developers with enough functionality to really build applications using the NFT framework. We’re aware of a handful of projects in development and look forward to seeing them finished and operational soon after the Emerald release.

What about the codebase update?
Although in the opening paragraph it sounds like NFTs and codebase will be ready for testing at about the same time they are really at different stages in the development process. They will not appear together in the Emerald release. Even if they were at the same level of completion it would be (too) risky with the resources at our disposal to release them at the same time. So the codebase update will be in the next release.

It might be possible is to include the next elements of the NFT framework in that release. Right now NFT framework and the codebase update are happening in parallel from basically the same starting point. So the Emerald code knows nothing about the codebase changes, and the new codebase knows nothing about the NFT framework. Those two branches will have to be merged and the result will hopefully be the base for the next release.
The other planned NFT framework functions are:

NFT protocols data update (plus associated Bitcore changes)
NFT burn (plus associated Bitcore changes)
NFT transfer and transfer authorisation (plus associated Bitcore changes)
NFT trading (expected to be an off-chain protocol using the Bitcore wallet service)


The timing and content of the next release will be dependent on how the market reacts to the Emerald one. Crown is producing really solid technological development but so far that is not reflected in the price. We need to see a good price bump from the Emerald release to be able to afford to continue the development effort.

Would you like to know more?
If you’d like to get involved in Emerald release testing, or have any questions or comments on this update, please let us know in Discord.
We have a weekly development call on Zoom every Thursday at 13:00 CET which any community member is welcome to join. Ping Artem in Discord if you’ve never attended before so he knows to let you in.
If you have a suggestion for a codename for the release after Emerald please let us know in Discord or Telegram. Continuing the (green) gemstone theme, one possibility is Verdite.

Community, technology and longevity
Crownfan at the NON central CONF in León, Spain


Today marks the 5th birthday of the Crown blockchain. A lot has happened in those five years and there is much still in the pipeline. Regular Crown contributor J. Herranz recently represented us at the NON central CONF in León, Spain.

In an interview about Blockchain DAOs he explained what makes Crown special. The interview was recorded and you can watch the whole thing (don’t worry, it’s only 11 minutes long) right here or on YouTube. https://youtu.be/gofzACx-mtE

If you want to jump to specific bits here’s the timeline and topic list.

0:17 What’s different about the Crown DAO?

2:20 How is the Crown DAO working out?

4:12 What is Crown’s most exciting project?

5:40 What is Crown’s unique selling point (USP)?

6:50 What is Crown doing to drive adoption?

8:10 Why did Crown move away from Proof of Work?

10:26 Where to learn more and how to get involved?


What’s your take on Crown and us celebrating our 5th birthday?
Are you a long-term community member or a relative newbie? Either way you probably have some anecdote or opinion of crownplatform.com and we’d love to hear it. Please comment here or for a more interactive experience, join us on Telegram or Discord.
