Non-fungible tokens (or NFTs) are unique blockchain-based tokens that can represent almost anything, including physical assets. NFTs have been growing significantly in popularity in recent years because of this potential to “tokenize” anything and provide a way to transfer ownership of digital assets to holders. An NFT can be described as a certificate of authenticity. Most NFTs today are based on the Ethereum blockchain, but some other blockchains like TRON and NEO also support NFTs.
