NFTs( non-fungible tokens) are unique electronic identifier’s that certifies ownership of any digital asset—a video clip, a tweet, a digital image.
These certificates of ownership are recorded on a blockchain, which you can think of as a secure digital ledger, traditional works of art such as paintings are valuable because they are one of a kind unlike digital files which can be easily and endlessly duplicated.
With NFTs, artwork can be “tokenized” to create a digital certificate of ownership that can be bought and sold. The token serves as a certificate of ownership of the art work. For example anyone can buy a painting of the Mona Lisa , But only one person can own the original copy.
Most NFTs are part of the Ethereum blockchain. Ethereum is a cryptocurrency, like bitcoin or dogecoin, but its blockchain also supports these NFTs, which store extra information that makes them work differently from, say, an ETH coin.
