Introduction to NFTs

NFTs make more sense once you stop treating them as expensive profile pictures and start treating them as unique records on a blockchain. The core idea is not art hype. It is digital ownership with identifiers that are meant to be distinct.

That distinction is what separates NFTs from the tokens most crypto users meet first. Fungible tokens are interchangeable units. NFTs are individual entries where token `#1` and token `#2` can point to different assets, rights, or history.

In practice, the NFT itself usually stores ownership and a reference to metadata, not the full media file. That means the token is the on-chain pointer and proof, while the experience people care about often lives one layer away.

This is why good NFT analysis starts with the contract model, not the marketing. If the token standard, metadata design, and rights model are weak, the visuals alone do not rescue the project.
