What an NFT actually is
An NFT, or non-fungible token, is a unique entry recorded on a blockchain that represents verifiable ownership of a specific digital, or digitally-linked, item. 'Non-fungible' just means not interchangeable: one peso coin is identical to any other peso coin, so pesos are fungible, but an NFT is deliberately made to be one-of-a-kind or part of a limited, individually-numbered set, so token #47 is not the same as token #48.
The token itself is usually small: it lives on the blockchain and mostly holds a pointer, called metadata, to whatever it represents, an image, a video, a piece of music, or something else, which is often stored elsewhere rather than directly on the chain. What the blockchain actually guarantees is the ownership record: who currently holds that specific token, and the full history of who held it before.
This is where the most common misconception creeps in. Buying an NFT of a digital artwork doesn't buy the image or its copyright, and it doesn't stop anyone else from viewing, screenshotting, or copying that same image freely. What changes hands is a verifiable, transferable ownership claim to that particular token, the equivalent of holding the signed certificate rather than owning the exclusive rights to reproduce the artwork.
Someone pays ₱55,000 for an NFT representing a piece of digital art, edition 3 of 10. Thousands of people can still right-click and save that same image for free, and the artist typically keeps the copyright unless it was explicitly transferred, but the blockchain record now shows this buyer, and only this buyer, as the holder of edition 3, a claim anyone can independently verify.
Mini quiz: When someone buys an NFT tied to a digital image, what have they actually purchased?
An NFT is a unique, non-interchangeable blockchain token that verifiably records ownership of a specific item, but buying one transfers that ownership record, not copyright over the underlying content.
