NFTs are helping artists solve a vital problem: who owns digital artwork?

Digital art can be easily and endlessly duplicated, but non-fungible tokens allow buyers to confirm ownership

The artist Kevin Abosch has sold a picture of a potato for $1.5m, made a neon sculpture inspired by cryptocurrency, and even sold his own blood on the blockchain.

So in many ways, entering the world of non-fungible tokens (NFTs) was the next logical step for the 51-year-old Irish artist, whose work explores themes of digital currency and value.
