What are NFTs?

Unique digital items on a blockchain, what they can and cannot prove, and what to check.

Simple definition

An NFT, or non-fungible token, is a unique digital item recorded on a blockchain that can show who holds it. "Non-fungible" means one of a kind, unlike a banknote that is the same as any other.

How it works

  1. A creator makes a digital item, like art, a ticket, or a membership pass.
  2. A record is added to a blockchain showing the item and its current holder.
  3. The holder can keep it, show it, or transfer it to someone else.

Everyday example

In real life

A festival issues digital tickets as NFTs. The holder shows the ticket from their wallet at the entrance.

Benefits and why this matters

Why this matters

NFTs got a lot of headlines, good and bad. Knowing what they really are helps you judge new claims calmly.

  • Creators can sell directly to fans
  • Clear proof of who holds an item
  • Can unlock access, like tickets or memberships

Risks and limitations

Things to watch out for

  • Watch out: Many NFTs have lost most of their value, and some never had real demand
  • Watch out: Owning an NFT does not always mean owning the copyright
  • Watch out: Fake collections and phishing links are common

Your beginner action

Try this

Look at a few NFT projects and ask: what does the holder actually get? If you cannot tell, treat that as a warning sign.
