Smart Contract NFT

A little about NFT's and their real usefulness, for the purpose for which it was created.

With all the hype generated by the phenomenon of NFT's, many developers have focused exaggeratedly on the idea of ​​art and the image associated with the non-fungible token, but NFT is not just for that.

The real usefulness of a non-fungible token is to be able to identify a unique identity within an application or ecosystem, e.g. a community in the metaverse can offer in its economy special privileges for a certain NFT and its holder, as well as resources or new characters in formats of NFT, ensuring anti-fraud control as each NFT has its own unique fingerprint.

This would be impossible to do with ERC20 format tokens, as tokens once moved between wallets can no longer be identified.

With the non-fungible NFT ERC721 tokens, it is possible to guarantee that a certain individual holding a certain UNIQUE TOKEN has already been rewarded or has already used his privilege within his application.

Even if this NFT token is moved within the blokchain, it is fully traceable and guaranteed as a unique identity.
