What are NFTs?

NFT is a digital asset that represents a piece of art. What makes an NFT unique is its digital signature created by blockchain technology. It defines the ownership of an asset that can be bought and sold for real money or cryptocurrencies. NFTs are not interchangeable as it represents unique assets owned by a specific person. It protects the metadata attached with the image rather than the visual data we see with our eyes, and where the actual value resides. CryptoPunks and CryptoKitties are some popular NFT collections.
