NFTs Explained Without the Hype

An NFT is a database entry proving which address controls a unique token. What that token points at, and what rights come with it, is a separate question entirely.

What an NFT technically is

A non-fungible token is an entry in a smart contract saying that token ID n is controlled by address x. Fungible tokens are interchangeable — any one unit equals any other. Non-fungible ones are individually distinguishable, which is the entire technical distinction.

The standard on Ethereum is ERC-721, with ERC-1155 handling collections that mix fungible and non-fungible items. The contract stores ownership; it does not usually store the content.

Instead, each token has a tokenURI pointing to metadata — a JSON file with a name, description and image link. That metadata frequently lives on a normal web server or on IPFS, and the image lives somewhere else again. This matters: if the server goes away, the token still exists and now points at nothing.

What you actually own

This is where expectation and reality diverge most sharply.

Buying an NFT transfers control of a token. It does not, by default, transfer copyright, reproduction rights, commercial rights or any legal claim to the underlying work. Copyright transfer requires a written agreement under the law of most countries, and a blockchain transaction is not one.

Some projects grant explicit licences — a few grant broad commercial rights, others grant limited personal use, and many grant nothing at all because they never addressed it. The rights you have are whatever the project's licence says, enforceable in ordinary courts like any other contract. The token does not change that.

What happened to the market

An honest account is worth more than either the promotional version or the dismissive one.

Trading volumes peaked in early 2022 and then fell by well over 90 %. Analyses of large samples of collections have found that the substantial majority now have negligible or zero trading activity. Many holders of collections that traded for tens of thousands of dollars cannot sell at any price, because liquidity has gone entirely.

The structural reasons were visible at the time: supply was unlimited while attention was not, most “floor prices” rested on very thin order books, wash trading inflated apparent volumes on some marketplaces, and the dominant use case was speculation on future speculation. When new buyers stopped arriving, there was nothing underneath.

Royalties, promoted as a durable income stream for creators, also proved fragile. Enforcement depended on marketplaces choosing to honour them, and competition drove most to make them optional.

What remains interesting

The speculative collapse does not make the underlying capability useless. Applications that do not depend on resale value continue to work:

• Identity and naming. Blockchain naming services map human-readable names to addresses, and the name is technically an NFT.
• Credentials. Non-transferable tokens representing qualifications or membership, where the point is verifiability rather than trading.
• Ticketing, where programmable resale rules can address scalping — though this requires venues to adopt it.
• In-game items with provable scarcity and portability between compatible applications.
• Provenance records for physical goods, where the chain is a tamper-evident log rather than the asset itself.

The common thread is that these use the token as a pointer and a record, not as a speculative instrument. That is a much smaller idea than the 2021 version, and a more durable one.
