At first glance, NFTs seem complicated and difficult to understand, but they are relatively simple.
In simple language, if an item can be replaced by any other item then it is said to be fungible.
A thing having importance of a personal or specific nature that cannot be replaced by another thing. It is non-fungible i.e. irreplaceable item.
A unique serial number is assigned to each token placed on the blockchain network. Each NFT has its own unique serial number.
The success of blockchain as an independent means of storing and authenticating information has given rise to a number of other ideas, one of which is non-fungible tokens, or NFTs.
NFTs can be associated with physical things as well as virtual or digital things.
Non-fungible means that it is the same in the whole world, that is, unique. It is a digital object which is designed in such a way that it cannot be copied and hence it is secure.
