Proof of ownership: Proof of ownership of (limited edition) physical items can be represented as NFTs and provide provenance (trail of ownership) in the world of arts.A tokenized representation of an identity on the blockchain could be used in voting systems or proof-of-individuality applications.A tokenized representation of an asset on a blockchain (e.g., CryptoKitties) - This could easily be applied to real estate holdings, art pieces, or even a car.In fact, NFTs are ushering in a new era of digital ownership-one in which goods like art, music, real estate, and even software can be represented digitally as non-fungible tokens on the blockchain. However, their utility and importance go far beyond just being a currency. NFTs have been used mainly as an alternative form of cryptocurrency. That asset could be anything from a digital baseball card to a digital house deed. The idea is simple: Instead of a blockchain securing a digital currency like Bitcoin or Ether, it secures a unique digital asset, just like a physical object. In contrast, each NFT is unique and cannot be exchanged with another identical token. The word "fungible" is used in economics to describe a good or asset that can be interchanged with other identical goods or assets for example, a kilogram of crude oil is interchangeable with any other kilogram of crude oil, and one kilogram of gold can be exchanged for another kilogram of gold.
A non-fungible token or NFT is a specific kind of cryptographic token or digital asset - in essence, any digital asset can become an NFT.
