NFT, or Non-Fungible Token, is a unique digital asset stored on a blockchain, ensuring it cannot be copied or replaced. Unlike cryptocurrencies like Bitcoin, each NFT has a distinct identifier, representing ownership of digital art, game items, virtual real estate, or collectibles. Blockchain ensures transparency in origin and transactions. NFTs are popular in digital art, gaming, and the metaverse, but their value can fluctuate wildly and carry risks of fraud. They offer great opportunities for creativity and investment, but caution is needed.
