NFT means non-fungible tokens (NFTs), which are generally created using the same type of programming used for cryptocurrencies. In simple terms these cryptographic assets are based on blockchain technology. They cannot be exchanged or traded equivalently like other cryptographic assets. Like Bitcoin or Ethereum.
NFT is a digital asset on the blockchain, that is unique and can’t be replaced with something else. Think of it as a one-of-a-kind certificate of authenticity, that can be traded, exchanged or kept forever.
It contains all the information related to the certification of a work: name of the work, name of the artist, number of prints, size, medium, etc. It serves as both a title de ed and a certificate of authenticity and as such replaces the physical certificate of authenticity.
