Le guide ultime sur les non-fungible tokens (NFT) : tout ce que vous devez savoir !

NFT – What is it?

NFT, or non-fungible token, is a type of digital token that represents a unique asset or object. Fungibility refers to something that can be replaced or exchanged for something else of equal value. In contrast, non-fungible assets are unique, one-of-a-kind assets that cannot be replaced or exchanged for anything else.

How does an NFT work?

NFTs are built on blockchain technology, mostly the Ethereum blockchain. They are created using the same smart contract technology that powers cryptocurrencies. The smart contract on the blockchain contains all the information about the NFT, such as its uniqueness, the owner, and the history of its ownership.

NFT versus Token

NFTs are a type of token, but they are different from regular tokens. Regular tokens, known as fungible tokens, are interchangeable with each other, just like currency. Each token has the same value as any other token in the same category. In contrast, an NFT is a unique token representing one digital asset or object. They are like digital certificates of authenticity.

Why are NFTs becoming popular?

NFTs have gained popularity because they allow for the ownership and transfer of digital assets that were previously impossible to claim ownership of, such as online artwork, music albums, game items, virtual land, and more. NFTs provide a way for creators to monetize their digital creations, enabling them to sell their work as one-of-a-kind assets.
