What is an NFT?
NFT stands for non-fungible token. In plain terms, it’s a record on a blockchain that points to a unique digital item and registers who owns that specific token. The token is “non-fungible” because it represents a single, distinct thing — unlike a Bitcoin or a pound, which are fungible and interchangeable.
An NFT can represent digital art, a music file, a video clip, a piece of code, or any other digital asset. The token itself usually contains or points to metadata: who created the item, when it was minted, and where the digital file lives. Ownership of the token can be transferred on the blockchain, and that transfer is public and verifiable.
Important: buying an NFT typically transfers ownership of the token, not the copyright in the underlying work. That’s similar to buying a painting: you own the physical object, but you don’t automatically get the right to reproduce it or control its use unless the creator explicitly transfers those rights.
There are well-known examples of high-profile sales that helped make NFTs widely talked about — auctions of digital works and tokenised artefacts showed the market’s interest in provenance and “signed” digital originals. But the core idea is the same whether a token sells for millions or for a modest sum: it records who owns a particular digital item.
Buying, selling and the risks to watch
How NFTs are created and sold
Anyone can create (or “mint”) an NFT, provided they use a blockchain and meet the platform’s requirements. Some platforms require creators to pay an upfront fee to record the token on-chain; others offer options that delay those costs until a sale. Marketplaces and smart contracts vary in how they handle royalties, editions (single originals or limited copies) and resale rules.
What you need to buy one
To buy an NFT you usually need a cryptocurrency wallet and some of the blockchain’s native currency. Transactions on the blockchain incur fees for processing — often called “gas” — and those fees fluctuate depending on how busy the network is. Marketplaces may also charge commissions or buyer fees, so the final cost can be higher than the listed price.
Checks before you buy
- Verify provenance: who minted the NFT and whether that person is really the creator. - Check what the token gives you: ownership only? any usage rights? royalty arrangements for future sales? - Inspect the metadata and hosting: is the digital file stored permanently on a decentralised service, or does it rely on a single web host? - Be cautious of identical copies: a jpeg you see online may be the same file that's been tokenised; the token’s value comes from its recorded provenance, not from exclusivity of the pixels.
Risks and practical cautions
NFTs are a speculative and evolving space. Prices can be volatile and illiquid. Scams, fake listings and copyright disputes exist. Blockchain costs and marketplace rules change over time. If you're creating NFTs, factor in upfront costs and whether you can realistically cover them. If you’re buying, treat it as buying a collectible rather than a guaranteed investment.
If you decide to explore NFTs, start small, learn how wallets and marketplaces work, and only commit money you can afford to lose. The technology opens interesting possibilities for artists and collectors, but it’s wise to be practical and cautious.
