An NFT (non-fungible token) is basically a unique digital asset stored on a blockchain that proves ownership of something online, like art, music, videos, or even in-game items. Unlike cryptocurrencies (like Bitcoin) which are interchangeable, each NFT is one-of-a-kind, so it can’t be swapped equally with another. In simple terms, it’s like having a digital certificate of ownership for something that can be copied, but only one person officially owns the original.
