What are non-interchangeable tokens (NFTs) and how can developers use them to develop functional applications?
Non-exchangeable tokens are a type of digital asset that is unique and cannot be replaced by another. They are used to create exclusive digital assets in the game, such as collectibles, players, or even characters. Non-exchangeable tokens can be used for a variety of purposes, including representing ownership of items, game characters, collectibles, various art objects, and possibly creating an in-game economy.
Developers can use NFT to create functional applications in their games, such as virtual economy, player statistics and achievements. This will allow future players to exchange goods and services. Many NFTs are already being created for use in popular games, such as collectible cards in online card games. The first non-interchangeable general-purpose token on Ethereum was CryptoKitties.
