I just got the update, so apparently we can edit NFTs directly on the blockchain! That's great! Good job guys!! I wonder if this Monitor can be on an app or in the wallet in the next evolution?

[ReD_Yaka_MoZ_]

Very interesting dear. I'm wondering how for example your CRW token that does the NFT can be useful?

Crown revolutionizes the Blockchain experience by holding, buying and trading fungible or non-fungible goods such as compatible with sales contracts, collections, stamps, numismatics, tamper-proof authentication, works of art or even 1 NFT = 1 human being, his history or anything he wants to spread about himself, as a personal crypto-money valid in the world directly related to a career and billions of possibilities.

For an artist who sells his paintings or sculptures, the value of the NFT token attached to his work will increase with the market value of the work. Art goes up and down all the time, but is a very stable asset if we consider that an artist can only go up if he works well enough to do so

Creating it under a single network useful for different systems makes a drastic difference since the mechanism of access, exchange and even pricing is totally revolutionary in its application! Note that it favors exchanges between peers, it is dematerialized, almost no storage cost, secure, forgery-proof, engraved in rock with the Crown blockchain which is entirely decentralized.

This new art form that changes the industry considerably for an artist.

The same is true for any craft that wishes to exploit Crown's NFTs.

"Owners of CRW and its NFTs are part of a community of avant-gardists (involved since 2014) in the emerging conversations about creative, multiple exploitation and financial domains. Users already have access to an online platform with a full program of exhibitions and exclusive content. They can also participate in IRL events where they can meet with other CRW owners, meet each other, vote on consensus - it's unparalleled because it's compatible with B2B, B2C, B2G, and virtually limitless fields of use.

To come back to my example as an artist:

When art meets money in the digital age, in general, the art and collectibles industry has benefited from the advantages of the blockchain. By registering a work of art on the blockchain, galleries and art registration services can ensure the transparency of the history and physical characteristics of the works of art.

Another example for collector cars is the ability to create an NFT under Crown CRW and index it to the value of collector cars. This way individuals can invest in several cars or even share them legally without an intermediary (just identified by an NFT or parts).

The applications and exploitation is a revolution, the story of your next decades is already there, with and without perspectives!

... allows to exchange goods materialized by NFT "addressed" to a specific and unique "thing", you, your property right etc... You can remain in control of your data at any time, it belongs to you in the dematerialization transcribed of any data in the Block of the Chain, redundant, indelible, unforgeable......

I get on the CRW moving train and I wonder... As I read The above EU directive - the NFT  project would also be affected in the ability to transfer say gaming assets from one environment to the other. Did you read paragraph 53 - that is insane
They want to integrate all the national registers.

The direktivet States that ingame assets are not covered Unless they are tradeable outside the games ecosystem
Trading with any virtuel asset or art or providing a Wallet are subjects under the directive
Yes  I know these integrations should not be a surprice - its just too invasive to the still existing national States and the privacy of the citizens of those States

By Wallet  they does not just mean mobile apps. But I guess we are all just testers

[ReD_Yaka_MoZ_]

The remittance industry has grown considerably over the past decade and will likely continue to grow in the coming years, Crown and its applications have a bright future ahead of them as long as the world learns what CRW is with simple tools that even grandma can easily use in 3 clicks.

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 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.

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.

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!

[ReD_Yaka_MoZ_]

very good reading here the potential is very interesting, according to you crown can it be compared to ethereum and its standards erc 721 what are the advantages of using crown?

yes Crown CRW can largely be compared to ERC 721


Is the useful platform for its accessibility, its openness for developments and its intelligent contracts. Its ecosystem works under the commands of the community (voting system), where everything that is used has been approved by all, as was the ERC20 token standard. The ERC-20 is a standard that has been proposed to make the tokens more suitable for normal activities (such as fiduciary currencies). This standard makes it possible to issue non-fungible tokens, i.e. to specify each token for a unique task, value or object. Its effectiveness in Cryptokitties has attracted the attention of new investors, who may well use it for other purposes.

A bit fuzzy? expand a bit on the subject 🙂

ERC, what is it?
The framework for the creation and development of Ethereum goes through what is called EIP (Ethereum Improvement Proposals). These are documents that propose new functionalities, updates or applications that will be developed within the platform. These EIPs are then validated or not by all members. The EIPs are thus, quite simply, proposals of functionalities. They are then submitted to a vote in order to validate or invalidate them.

The higher version is available from Crown at https://www.crownplatform.com/governance/

In this sphere, there are innumerable topics that can deal with interfaces, intelligent contracts, consensus, networks or block and data management. ERC or Ethereum Requests for Comments is a category of EIP, which manages the domain of the token standard, including ERC-20, which is a consensus adopted within the community and is characterized by its fungible property. But there are many ERCs, each of them offers a small feature adapted to a specific use such as ERC 190 for smart contracts, ERC-181 for addresses, ERC-162 for hash etc.

EIPs are "proposals".
ERC concerns the token standard
ERC-20 was the 20th proposal
ERC-721 was the 721st proposal.


And ERC-721, how does it work?
Contrary to the ERC-20 standard which is known to everyone, the ERC-721 proposes a different use which is characterized by non-fungibility (NFT: Non Fungible Token). This particularity relates to a personal identification of each token. To better understand this specification, let's take the case of the Cryptokitties game where the ERC-721 plays a major role.

Cryptokitties is an online game whose goal is to collect virtual chats, which have a unique value. The non fungible character will allow in this case to specify the types of cats but also their peculiarities (such as eyes, paws, colors, etc). Among other things, the tokens are unique and refer to a physical or digital value, not storable as crypto-active of the same value (but of the same rank). In 2017, CryptoKitties made the buzz and ended up attracting a colossal number of players who like to collect (just like Pokemon Go or other types of online games that are about treasure hunting)!

After this buzz, other investors have understood the value of this technology and are already planning to extend it to real estate, artwork or other unique value trading. Let's say: 1 non-fungible (unique) token = a unique material asset. Thank you ERC-721. Yes it's as simple as that. Like the ERC-20, the ERC-721 has a specific objective to improve the process of using the Ethereum platform. A few conditions define the model and differentiate it from the others.

First of all, ERC-721 tokens are non-fungible. This characteristic is summarized in the term NFT (Non Fungible Token), which implies a unique identification number for each token. Secondly, they are tokens that cannot be subdivided because they represent a particular whole as explained for the case of CryptoKitties, i.e. an ERC-721 token for a real value such as a colour or a particular good (it cannot be subdivided to the thousandth or hundredth, so 1 token remains the smallest reference).

You wouldn't want to dismember your virtual chat? Wouldn't you? Voila! Let's say that a non-fungible token is "whole" and unique.

The case of using several units is possible despite the personal identification of each token, however, we won't be able to store ERC721 tokens as peers.

A token with a very great potential
Anything in the area of personal identification can be governed by ERC-721. The closest example has been that of collector's games, but in another, more economic context, it could encompass a very large number of fields such as works of art or even land ownership.

Indeed, the registration of a parcel of land can be secured by non-fungible token technology. As in the case of the Fieldcoin project, the two types of coins including the ERC-20 and ERC-721 have been mixed for two different uses: the ERC-721 will be used for matching parcels of land (for the notion of uniqueness) while the ERC-20 will be used for standard exchanges (of money) on the platform.

Fungible vs Non-Fungible tokens

NFT Framework
Simple recording of assets on the blockchain. The NFT (non-fungible tokens) framework is a registry subsystem that allows the community to register physical or digital assets on Crown's blockchain.

What are non-fungible tokens?
NFTs offer unique features that make them different and digitally rare. Take airline tickets for example - although they look similar, they contain passenger information that is unique. The same goes for cars, people, buildings, legal contracts, patents - basically, most physical and digital assets are non-fungible: and therein lies the enormous opportunity for NFTs. NFTs have unique properties, just as one asset is not equal to another asset in the same set, so are non-fungible tokens. Most tokens such as crypto-currency are fungible - they are primarily monetary and interchangeable, so is money.

Technical documentation of the NFT framework
The technical manager, Artem, has published a technical documentation of the NFT framework on Medium and a series of 3 educational videos for developers.

Use of NFT tokens
NFTs can be used in a variety of real-world use cases where asset registration is desirable or required. Very good examples can range from intellectual property registries, antique watches, digital art, endangered species or trees, medical records, real estate, legal contracts, notary services and many other examples. What is exciting about these registers is that they are recorded forever on an independent and democratically managed blockchain, which is governed by the decentralized autonomous organization of the Crown. The owners of NFTs can use these records as immutable proof that these assets - documents, know-how, cars, insurance policies, medical records, intellectual property, etc. - exist and have specific non-fungible characteristics at the time they are time-stamped on the blockchain .

Very good exchange and analysis seen on Crown's discord that I report here:

@Crownfan says: "Look - if we tighten the order book and reduce the spread, the "abusive" robots can't do much. action - reaction. crypto is unstoppable.
some teams/projects hire market makers. we have never done this, that's why the btc-crw market is at the charge of the community/traders/bots. the higher the liquidity, the less manipulation. as the liquidity is low, it is easier to manipulate the price - unfortunately this also happens for many other low cap alts (and also high cap - even BTC!). Many alternative operators have been getting rekt due to the rise of BTCs in recent years and the sale of whales, so it is normal that people are cautious and only queue up at the support lines.

It also makes sense that people who use a fiat broker sell when the price of the BTC rises, because their relationship with the fiat is also higher. I guess people use brokers to trade parts and make a profit, so you can't really blame them. But remember, dealers only sell to buy - and buy to sell, so they'll come back if they can make a profit.
Don't be fooled by the fake pumps and develop a self-contained definition of the value of the coin you own or use. Price is and always has been artificial

our big resistance line is at around 900 sats. You see many alts going 3x 4x these days. that is because they managed to break their resistances, which had also been accumulating for a year. For Crown it looks like this:




anything between these ranges is not relevant for the market. Still, there is a lot of spread, which is what causes the effects you mention.
our goal as a project and contributors is to provide a solid code and make it easier for use cases to progress. if these things align, then the market responds accordingly. Seeing it the other way (price -> project relationship) does not get us anywhere.
still, the fixation is there, because Crown depends on valuation to define its available resources.
i hope you can understand so that together we become stronger. its the only way.

@Gohar say: I think every participant in the project can make a positive contribution to the valuation of Crown by consistently using their coins to operate their own nodes. Increased competition for the rewards not only strengthens the network through increased security, but also helps to stabilize the price. As we all know, running nodes costs money. From an economic perspective, the node's rewards should at least cover the costs in the medium term. However, if there is less reward for each node due to increased competition, it will be more difficult to achieve this goal with the same price level. It can therefore be assumed that a continuous increase in the number of nodes will result in a positive price development.
