NFTs are non-fungible digital assets on a blockchain with unique identification codes and metadata that distinguish them from each other.

 

Unlike cryptocurrencies, they cannot be traded or exchanged at equivalency. This differs from fungible tokens like cryptocurrencies, which are identical to each other and, therefore, can be used as a medium for commercial transactions.

Not only can they have a value within the art it self but also can have real-world use cases, such as the deeds to your car or keys to your house, NFTs are growing massively especially when you're applying them to the metaverse.
