What Is an NFT? Ownership, Royalties and Marketplaces
A plain-English guide to NFTs: how ownership works on a blockchain, how creator royalties are set and paid, and how marketplaces list and sell them.
Key points
- An NFT is a unique digital token on a blockchain that can record who owns a specific item.
- Ownership is tracked on a public ledger, but the actual file (image, video, etc.) usually lives elsewhere.
- Royalties and marketplace rules are set by smart contracts and platform policies, not by law.
What is an NFT?
An NFT (non-fungible token) is a unique digital token recorded on a blockchain. “Non-fungible” means it is not interchangeable with another token of the same kind — unlike, say, one bitcoin, which is identical to another bitcoin. Each NFT has its own identifier and can be linked to a specific item, such as an image, video, audio file, or virtual land.
When people say they “own” an NFT, they usually mean they control the blockchain address that holds the token. That control is recorded on a public ledger and can be transferred. But owning the token is not the same as owning the copyright to the artwork or having the file stored on the blockchain itself.
How ownership actually works
An NFT lives on a blockchain, most often Ethereum, though other chains support them too. The blockchain records which address holds the token. To move an NFT, you sign a transaction with the private key for that address. Whoever controls the private key controls the token.
The item the NFT points to — the image, video, or document — is usually not stored on the blockchain. Instead, the token contains a link, often to a decentralized storage system like IPFS or to a regular web server. If that link breaks or the file is removed, the token still exists, but the content it points to may not be accessible.
This separation matters. Buying an NFT generally gives you the token and whatever rights the creator has attached to it. It does not automatically give you copyright, trademark, or the right to reproduce the work commercially. Those rights come from a separate license or agreement, if any.
How royalties work
Royalties are payments to the original creator when an NFT is resold. They are not automatic on most blockchains. They are enforced by the smart contract that created the NFT and by the marketplace where the sale happens.
When an NFT is minted, the creator can set a royalty percentage — for example, 5% or 10% of each secondary sale. If a marketplace honors that setting, the creator receives that share when the NFT is sold again. If a marketplace does not honor it, the creator may receive nothing from that sale.
In practice, royalty enforcement has become uneven. Some marketplaces have made royalties optional for buyers or sellers, and some have stopped enforcing them altogether. Creators who rely on royalties should check the rules of each marketplace and understand that enforcement can change.
How marketplaces work
An NFT marketplace is a platform where people can mint, list, buy, and sell NFTs. It connects to your crypto wallet. You approve transactions, pay network fees (often called gas), and the marketplace handles the listing and sale process.
Marketplaces differ in several ways:
- Which blockchains they support. Some focus on Ethereum, others on Solana, Polygon, or multiple chains.
- Royalty policies. Some enforce creator royalties; others make them optional or ignore them.
- Fees. Platforms charge a percentage of each sale, and there may be additional network fees.
- Curation. Some are open to anyone; others review or approve creators.
When you list an NFT, you are not moving it to the marketplace. You are approving the marketplace to transfer it on your behalf if a buyer meets your price. The token stays in your wallet until the sale is completed.
Practical steps: buying and selling an NFT
- Set up a wallet. Use a self-custody wallet that supports the blockchain you plan to use. Keep your seed phrase offline and private.
- Fund the wallet. You will need the blockchain’s native token to pay for purchases and network fees.
- Choose a marketplace. Check which chains it supports, its fee structure, and its royalty policy.
- Connect your wallet. The marketplace will ask for permission to view your address and, later, to approve transactions.
- Buy or mint. To buy, pay the listed price plus fees. To mint, upload your file, set royalties if the platform allows, and confirm the transaction.
- Store and manage. Your NFT stays in your wallet. You can list it for sale, transfer it, or hold it.
Always double-check the contract address and the collection name before buying. Fakes and copycats are common.
Risks and common mistakes
- Confusing the token with the artwork. You may own the NFT but not the copyright. Read the license.
- Assuming royalties are guaranteed. They depend on the marketplace and can be changed or ignored.
- Ignoring network fees. Gas fees can be high and vary with network demand.
- Falling for phishing. Fake marketplaces and wallet-drainer links are widespread. Never share your seed phrase.
- Buying illiquid items. An NFT may be hard to sell quickly, and its market value can drop sharply.
- Overlooking storage. If the file is hosted on a central server, it can disappear. Decentralized storage reduces but does not eliminate this risk.
- Trusting hype. A high price does not guarantee lasting value or a working product.
A quick comparison
| Concept | What it means | Common misunderstanding |
|---|---|---|
| NFT | A unique token on a blockchain | That the file itself is on the blockchain |
| Ownership | Control of the wallet holding the token | That it includes copyright |
| Royalties | Creator share on resale, set in the contract | That they are always paid |
| Marketplace | Platform to list and trade NFTs | That it holds your NFT |
Summary
An NFT is a unique blockchain token that can represent ownership of a specific digital item. Ownership means controlling the wallet that holds the token, not owning the underlying copyright. Royalties are creator payments on resales, enforced by smart contracts and marketplace policies that can vary. Marketplaces are platforms where NFTs are listed and traded, and they connect to your wallet. Before buying or selling, check the license, the royalty rules, the fees, and the storage of the file. Treat NFTs as speculative assets and secure your wallet carefully.
