Non-fungible tokens (NFTs) are unique digital assets that are stored on a blockchain, typically using the Ethereum blockchain. Each NFT has a specific and distinct value, metadata, and ownership that can be verified using blockchain technology. NFTs work by creating a digital certificate of ownership and authenticity for a specific digital asset, such as artwork, collectibles, or virtual real estate. These tokens can be bought, sold, and traded like physical assets but exist purely in the digital realm. Ownership of an NFT is recorded on the blockchain, providing a transparent and secure way to prove ownership and transfer of these digital assets.
