An NFT, or non-fungible token, is a type of digital asset that is unique and cannot be replicated. NFTs are commonly used in the world of cryptocurrency and blockchain technology to verify the authenticity and ownership of digital assets, such as artwork, collectibles, and other forms of digital media.

NFTs can be bought and sold like any other piece of property, but they have no tangible form of their own. They are secured by blockchain technology, which makes them tamper-proof and ensures their authenticity. Because each NFT is unique and cannot be replicated, they are often seen as a way to establish ownership and scarcity in the digital world.
