Re: [ANN][CRW] CROWN (MN-PoS) | Platform | NFT framework | Governance

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.

Crown offers the cheaper equivalent, more secure (MN) and better!

Why is this? Why? How?

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 .
