NFT tokens can be used for digital assets that need to be distinguished from each other, like crypto collectibles like CryptoKitties, to prove their value or scarcity. They can represent everything from virtual plots to artwork to ownership licenses. NFTs are not traded on standard cryptocurrency trading platforms, but are bought and sold on digital marketplaces like Opensea or Decentraland's LAND Marketplace. Tokens like Bitcoin and other Ether-based ERC-20 tokens are fungible. Ether's non-fungible token standard, used by platforms like CryptoKitties and Decentraland, is ERC-721. NFTs can also be created on other smart contract-enabled blockchains through the NFT tool and While Ether was the first to be widely used by NFTs, NEO, EOS, and TRON, all now have NFT standards. NFTs and their smart contracts allow for the addition of detailed attributes such as the identity of the owner, rich metadata, or secure file links. the effectiveness of NFTs to irrevocably prove digital ownership is an important advance for an increasingly digital world. They can see the promise of blockchain's trustless security applying to the ownership or exchange of virtually any asset. As with the challenges blockchain has faced to date, NFT and its protocols and smart contract technologies are still evolving. Creating decentralized applications and platforms for managing and creating NFTs is still complex. In addition, there is the challenge of creating standards. Blockchain development is fragmented, with many developers working on their own projects. To be successful, there may need to be uniform protocols and interoperability.
