NFT (Non-Fungible Token)
Non-Fungible Token
A digital token issued on a blockchain with a unique identifier
In Simple Terms
An NFT is a "marker (token) with a unique ID" issued on a blockchain. With digital art, for instance, the image file can be copied by anyone — but the token has its own unique ID, and the blockchain records which wallet (a digital wallet) currently holds it. So what's truly one-of-a-kind isn't the image data itself, but the token (ID) on the blockchain. This setup lets tokens linked to digital art or game items be bought, sold, and transferred, and anyone can check on the blockchain at any time which wallet holds a given token.
Behind the Name
NFT stands for Non-Fungible Token. Non-Fungible means "cannot be substituted" — in other words, it has no interchangeable equivalent. Token refers to a mark or identifier. Put together, it means "a one-of-a-kind mark that can't be swapped for anything else."
Take a Closer Look!
NFT stands for Non-Fungible Token — a digital token issued on a blockchain with a unique ID.
Take digital art as an example: anyone can copy the image file itself, but with an NFT, the blockchain records which wallet (a digital wallet) currently holds the token. What's unique isn't the image data — it's the token on the blockchain, which carries a unique ID and a full history of ownership and transfers.
Note that holding a token is separate from holding copyright or usage rights to the work; those are governed by separate contracts or terms of service.
Technically, NFTs live on a blockchain — a distributed ledger that is extremely difficult to tamper with. Each token is assigned a unique ID; creators can also limit how many tokens are issued to create a sense of scarcity, and the full history of ownership transfers is permanently recorded. The actual content (image, video, etc.) is typically not stored on the blockchain itself; the token instead holds a reference to where that content lives (such as a URL). Also, what the blockchain shows is a wallet address (a string of letters and numbers) — it doesn't directly reveal who the real-world owner is.
NFTs are used mainly for digital art, in-game items, and memberships. Artists can mint and sell tokens tied to their work, and players can trade in-game item tokens with each other. Tokens can be bought, sold, and transferred, with ownership always verifiable on the blockchain.
