NFTs are digital assets used to represent ownership of unique objects, be they virtual or physical. NFTs are registered on a blockchain: in this way, the absence of possible manipulation of information over time is guaranteed.

NFT stands for 'non-fungible token'.
Fungible objects can be interchanged because it is their value that defines them rather than their unique properties. For example, a dollar is fungible because it has the same value as any other dollar.
Non-fungible objects are not interchangeable because they have unique properties that give them a value. A typical example is works of art.

A smart contract is a self-executing contract with the terms of the agreement between the parties being directly written into lines of code.
The code and the agreements contained therein exist across a distributed, decentralized blockchain network where transactions are trackable and irreversible.

NFTs can be used to store information on digital and physical assets (such as ownership) and offer, especially in the industrial field, new services and business models.
OEMs, system integrators and distributors can use NFTs to protect the material and virtual ownership of their know-how and propose new services based on transparency.
