What are NFTs?
NFTs (non-fungible tokens) are intended to be unique digital identifiers; a kind of “uncompromisable digital record”. They are not in fact anything like this, but this is what they claim to be.
The main uses for them so far has been to make digital art “scarce” — by making one copy the ‘original copy’, allowing it to be sold like a traditional artwork would be at a far higher price than a normal digital image could be sold for. (The price of high-price traditional art is also a scam).
