An NFT, or a non-fungible token, is a type of digital signature that allows anyone to verify the authenticity and ownership of an asset. The digital record is saved on blockchain ledgers that can be read by anybody looking to find out the owner of the asset. Blockchain is also the technology driving the cryptocurrency market.

NFT enthusiasts hope these digital assets will retain value because it is possible to distinguish the original work from copies. They compare it to the original Mona Lisa painting at the Louvre Museum, which is unique and priceless.

Digital objects can be minted as NFTs and traded as assets, including art, sports collectibles, patches of land in virtual worlds, cryptocurrency wallet names, and even tweets.
