What is an NFT?

NFT is the abbreviation or acronym for Non Fungible Token. In clearer terms let's take money as an example, which is an asset that is fungible in the area of economics is a thing that is interchangeable; unlike something that is not fungible can not be, it is impossible to exchange because it has unique properties. The Non-Fungible Token (NFT) is the representation of an asset that is unique and a token model of a blockchain, this token is also usually fully digital or be real world assets being tokenized versions. A non fungible token is unrepeatable and unique, this means that it cannot be fractionalized but we can use it to represent things from the real or digital world with its own attributes, then keeping everything by means of a smart contract within a blockchain platform as it is in the Ethereum block sequence.

How does an NFT token work?

NFT tokens work in different ways according to the blockchain platform where their execution takes place. NFTs act in different ways since each blockchain platform has its own sequences of capabilities.
The differences that each platform has are minimal, they are adjustments that are executed so that the smart contracts are conditioned to the blockchain where they are executed (the way they are entered, also the programming language used and the requirements that can be used within the network and its limitations). So the function of NFTs follows the factors we call standard and mainly follows the structure mandated by Ethereum ERC-721 and the more recent ERC-1155, thus creating tools to streamline and facilitate the elaboration of NFT tokens within Ethereum.

Project uses NFT : Gods Unchained

Gods Unchained is a digital collectible card game that is founded on Ethereum ERC721 standards, and they are tokens with the qualities of being collectible and are interchangeable because their main feature when using NFT is to be unique. Cards are cast as NFTs on the blockchain. And each card is unique, also users (players) will be able to get it and to make an exchange it must be with the one with equal ownership level.
The meaning of being unique and exchangeable, is that each player truly owns their digital cards and they have full control in what to do with their cards.

Sourse

As the game uses the Ethereum blockchain effectively, and to clarify the form of the game not all activities must go through the blockchain, because it would lead as consequences would be slow and high cost to play, only be recorded in the purchase and exchange of new cards, not to sacrifice the speed and playability the rest of the game will be held on a server that is centralized to protect the originality, rarity and the unique qualities of the cards to the MTG way in the virtual world.

Conclusion

In short, cryptocurrencies, NFTs do not exist two or more alike and cannot be replaced or exchanged among them because they are unique tokens, in comparison as it would be a work of digital art. Allowing them to be easily traded at the time of acquisition by buying and selling them.
As time goes by, the number of projects with great potential uses of NFT continues to grow, such as today's game Gods Unchained, which is a unique digital collectible card game.
Digging deeper will quickly show the backend of Gods Unchained how the blockchain is enabling this game to rise further above the competition that are not running on the blockchain.
