what is an NFT? – francecrypto.fr

An NFT (Non-Fungible Token) is a type of digital token that represents a single, indivisible asset, such as a digital artwork, photo, tweet, concert ticket, etc. Unlike cryptocurrencies, which are standardized and interchangeable tokens, each NFT is unique and can only be exchanged for an equivalent value. NFTs are often used to certify the authenticity and ownership of digital items, as a way to “lock” a digital file to prevent it from being copied or modified without permission.

Definition and explanation of an NFT


A non-fungible token (NFT) is a special type of cryptographic token unique and indivisible. Unlike an Ethereum token, this one cannot be split into multiple fractions.
By comparison, fungible tokens can be stacked on top of each other indistinguishable from each other. (Example: I have 10 $ETH, in this case my wallet displays 10 $ETH, instead if I have 10 NFTs my wallet will display 10 different tokens.)

Means that each fungible token has exactly the same valuewhile non-fungible tokens can each contain a level of unique value according to their individual identity.

Non-fungible tokens have many potential use cases.
One of the most common applications for NFTs is the use in blockchain-based games.


To get NFTs you will need several things. First of all from a ethereum wallet compatible, i.e. that can receive this type of token.

NFT standards: ERC-721 or ERC-1155


Not all NFTs are created equal. This is what we will see when comparing the ERC-721 and ERC-1155 token standards.

The token standard ERC-1155 was created to function as a vending machine, where developers could implement a single smart contract that can be used to create unlimited fungible (identical) tokens and non-fungible (unique) tokens.

In comparison, the standard token ERC-721 it only produces non-fungible tokens and requires developers to implement a new smart contract for each new token.

To put it simply, the ERC-1155 standard allows for the duplication of unique tokens within the same instance. For the end user there is no difference in the end!

Use cases


NFTs have many possible use cases, but here are some common examples:

  • Selling digital artworks: Artists can use NFTs to sell unique artworks online, assigning them an NFT token that certifies their authenticity and ownership. It can be a way for artists to monetize their work and ensure their art is recognized and protected.
  • Collecting Virtual Goods: Players can use NFTs to collect unique virtual items in online games, such as rare weapons or character outfits. This can add a dimension of real value to virtual goods, allowing players to trade or resell them for real money.
  • Data Ownership: Businesses can use NFTs to store and protect sensitive data, such as contracts or licenses. This can help ensure data integrity and authenticity, preventing unauthorized changes.
  • Concert ticket sales: Concert organizers can use NFTs to sell unique concert tickets by assigning them an NFT token that certifies their authenticity and ownership. This can help fight counterfeit tickets and ensure that only legitimate holders have access to events.

So rare

Sorare is a French fantasy football web-app or dApp in which you can collect players’ cards.

Furthermore, you can buy and sell cards to other players, speculate on the value of the cards but also compose a team with characteristics related to the performance of (real) players and participate in online tournaments.
