A NFT is a digital asset that represents real world objects like art, music, in-game items and videos. They are bought and sold online, frequently with cryptocurrency and they are generally encoded with the same underlying software as many cryptos. NFT is more secure than a typical digital transaction because the records are kept in blockchain which offers a public record that is “Unhackable” and helps combat misappropriation. At a very high level, most of the NFT's are the part of Ethereum blockchain. Ethereum is a cryptocurrency like bitcoin but it’s blockchain also supports these NFT's which store extra information that makes them work differently.
