Non Fungible Token (NFT)

Here is a non technical article on NFT which serves as an introduction to the NFT topic.
NFT properties

  • Each token is unique
  • Cannot be replaced
  • Cannot be subdivided

For example, a plane ticket is unique — it specifies a specific seat, on a particular flight, at a specific time.

NFTs enable owners of a unique item to prove their ownership and the authenticity of an item.

NFTs live on a distributed ledger (DLT) within an associated account. The original creators of the NFT control the private key of that account where the NFT lives, and they are free to transfer that NFT to any account.

The buyer of the NFT owns a “token” that proves they own the “original” work.

anyone can create NFT based on digital items generated by other people.

  • Content :

a creator may mint different NFT’s for the same digital asset by making indistinguishable duplicates, such as with varying types of file (mp3 vs. mp4, png vs. jpeg, etc.)
