What is NFT? It’s a Non Fungible Token and it authenticates your digital media as yours. This is one of the most attractive features. The other attraction to this is that you can build in a royalty to your art and media. If it gets sold, built into the code is that royalty so that you are paid as the original creator.
Filmmakers are accustomed to royalties but most original creators are now able to gain the benefits of affirming ownership and receiving royalties for your work online.
There are ways you can save an NFT, of course, just as any art or photograph online. However, collectors or buyers now have a way to verify they own a genuine work of art.
