The Open Market, Isn't It a Good Idea?

Nft is an app that lets users buy and sell text books on the open market. The author gets a percentage of the resal value, but also some sort of royalty for each book sold. Nft uses smart contracts to make it more efficient so students don't have to go through three or four different used book resallers before they get their money back. It's easier to resell. Students are happier with nft in general.
