This is a stark contrast to fungible assets, such as a US dollar bill. Any US dollar bill can be exchanged for another dollar bill and it is worth the exact same and has the same characteristics. NFTs cannot be exchanged for one another since no two NFTs are the same. Each has its own value and characteristics. Some of these characteristics are visual or digital assets, such as digital art or a virtual item in a video game. Each NFT secures the information associated with it, such as ownership, asset history, cryptocurrency resale value, by encoding and cryptographically securing it.
