What is an NFT?

NFTs, or non-fungible tokens, are unique digital assets representing a specific data unit stored on a digital ledger such as a blockchain network. This data can also represent a real-world item in the digital realm, such as art, music, videos, and more. Unlike cryptocurrencies, each NFT is one-of-a-kind and cannot be exchanged for something similar.

How are NFTs different from cryptocurrencies?

NFTs are one of a kind and naturally exclusive based on their specific data, in contrast to cryptocurrencies, which are fungible and interchangeable.

For example, if you exchange some of your bitcoin for another bitcoin, you will still have bitcoin, and the exchanged bitcoin will still have the same value. However, NFTs are intentionally created to be unique and collectible, ensuring each is unique and has different specific data.

  • ERC-1155 allows for the issuance of semi-fungible tokens. This is commonly used for in-game NFTs, representing items like weapons, health packs, or skins.
