An NFT, or non-fungible token, is a unique digital asset that represents ownership of a specific item or piece of content, such as artwork, music, or a video. Unlike cryptocurrencies such as Bitcoin or Ethereum, which are fungible and can be exchanged for one another, NFTs are non-fungible and cannot be exchanged for other tokens on a one-to-one basis.

​

NFTs are created on blockchain networks, typically using the Ethereum network, and are stored on a distributed ledger, which makes them transparent, secure, and tamper-proof. Each NFT contains a unique digital signature that verifies the authenticity and ownership of the asset.

​

NFTs have gained popularity in the art world as a way for artists to sell and authenticate their digital artwork. NFTs have also been used in the gaming industry, where they can represent in-game items and provide a way for players to trade and sell their digital assets. Additionally, NFTs have been used to create unique collectibles and limited-edition merchandise.

​

The value of an NFT is determined by the market demand for the specific asset it represents. Some NFTs have sold for millions of dollars, while others have a lower value depending on their popularity and scarcity.
