NFTs (Non-Fungible Tokens) are unique digital tokens that certify ownership of a digital or physical asset, usually stored on a blockchain (often Ethereum). Here is a simple and clear overview:

1. What is an NFT?

It is a unique digital asset (non-fungible = non-interchangeable).

Unlike cryptocurrencies like Bitcoin (where each unit is identical), each NFT is distinct.

It contains metadata: title, description, owner, image, etc.

2. What are NFTs used for?

Digital art: artworks sold in digital form.

Video games: unique items, land, or characters to own or trade.

Music & videos: titles or clips with ownership rights.

Ticketing & events: verifiable and unique tickets.

Fashion & luxury: digital certificates for clothing, accessories, etc.

3. How to buy or sell an NFT?

Create a crypto wallet (e.g., MetaMask).

Buy ETH (often used for NFTs).

Go to an NFT platform (OpenSea, Rarible, Binance NFT...).

Connect your wallet, choose an NFT, buy or list for sale.

4. Advantages

Traceability and authenticity guaranteed through the blockchain.

Revenue for artists: automatic royalties with each resale.

Possibility to create communities around a collection.

5. Disadvantages

Excessive speculation: some NFTs have no real value.

Environmental impact (although this is decreasing with new blockchains).

Risk of plagiarism or theft of digital works.
