What Is an NFT? Non-Fungible Tokens Explained

NFTs went from a niche idea to a headline word very quickly, and a lot of the noise buried the basic question. What is the thing you're holding when you hold one? The short version is that it's a unique token recorded on a blockchain.

I've based this guide on ethereum.org's NFT explainer and security page, with the FCA's warnings alongside. It's general education, not financial advice, and I'm not suggesting you buy, sell or collect any NFT.

NFT meaning: unique tokens on a blockchain

NFT stands for non-fungible token. Something fungible can be swapped for an identical item, like one coin for another. A non-fungible token can't. ethereum.org says "Each NFT has different properties (non-fungible) and is provably scarce."

That's the key difference from tokens such as stablecoins, where every unit is the same. If you want that comparison, here's how a stablecoin works.

What an NFT can represent

ethereum.org lists a wide range of uses, well beyond digital art:

• Art and collectibles
• Tickets and proof of attending an event
• Proof of completing a course
• In-game items
• Domain names and online identity
• Access to content
• Real-world items such as property, which can be tokenised

How NFT ownership is recorded

An NFT is built as a smart contract that follows an Ethereum standard. ethereum.org links to two, called ERC-721 and ERC-1155. The contract creates tokens, gives each one an ID and links it to an Ethereum address. Minting is the step that gives a wallet ownership of a specific token.

Ownership is stored on the blockchain for anyone to verify publicly. Creators can also build in rules, such as a maximum supply or a royalty on resales. If smart contracts are new to you, my explainer on smart contracts covers the basics.

What owning an NFT does not automatically give you

This is where people get caught out. Owning an NFT means owning a token that points to something. It doesn't automatically protect the file it points to, and ethereum.org notes that copies often can't be distinguished from originals. It doesn't automatically give you copyright or the right to use the work commercially either. Check what the creator says the token includes.

NFT risks and scams to know about

ethereum.org says NFT security issues are most often related to phishing scams, smart contract vulnerabilities or user errors. Access to your NFTs depends on your wallet, so exposing your private keys or recovery phrase puts them at risk.

• Airdrop scams, where a scam project sends an NFT or token to your wallet to lure you in.
• Giveaways, which ethereum.org says are always scams.
• Approval traps, where unlimited spend limits could let a contract drain your wallet.
• Requests for your recovery phrase, which no legitimate service will make.

The FCA adds that crypto is high risk, that it isn't regulated yet in the UK and that you should be prepared to lose all the money you put in. Many fake projects follow the pattern I describe in what a rug pull is.

Telling a real NFT project from a risky one

There's no foolproof test, but some habits help. Look for a team you can verify, read the contract details, and be suspicious of pressure to act quickly. If someone you don't know sends you an NFT unprompted, don't connect your wallet to claim it.

What happens when you mint or move an NFT

Minting is the moment a token is created and assigned to a wallet. After that, ownership can move from one address to another, and ethereum.org says the record is on the blockchain for anyone to see. Each action needs a transaction from your wallet, which is why it matters to read what you're approving. A request you don't understand is a good reason to stop.

Questions to ask about any NFT

1. What does the token include? A picture, access to content, a ticket? Check the creator's own terms.
2. Who made it, and can you verify them? Anyone can create a token that looks like someone else's work.
3. What rules are built in? ethereum.org says creators can set a maximum supply or a royalty on resales.
4. Where is the file stored? The token points to something, and the token alone doesn't protect that file.
5. Does anything ask for your recovery phrase? If so, it's a scam.

None of this needs technical skills. It simply slows you down enough to notice when something is off, and that's most of what keeps people out of trouble with tokens of any kind.

Writing about NFTs for a wider audience

Balanced NFT writing is rarer than hype or dismissal. If you cover digital collectibles or tokens, you may want to reach other readers.

I keep a short directory of crypto blogs that take articles from outside authors for anyone writing in this space.

Frequently asked questions

What does NFT stand for?

It stands for non-fungible token. ethereum.org says each NFT has different properties and is provably scarce, unlike identical tokens that can be swapped one for one.

Does owning an NFT mean I own the artwork?

Not automatically. You own a token recorded on the blockchain. ethereum.org notes that copies often can't be told apart from originals, so check what rights the creator grants.

Where is NFT ownership recorded?

On the blockchain. ethereum.org says an NFT contract assigns each token an ID and links it to an address, and that ownership can be verified publicly.

Are NFTs safe from scams?

No. ethereum.org says NFT security issues are most often phishing scams, smart contract vulnerabilities or user errors. Never share your recovery phrase.

Can NFTs only be digital art?

No. ethereum.org lists tickets, in-game items, domain names, proof of attendance and access to content, and says real-world items can be tokenised too.
