NFT Storage
For quick recall, a Non-Fungible Token is not a physical or digital item itself. It is a smart contract between the buyer and the seller. The smart contract provides the rights to distribute, use, and re-sell the asset.
Some creators add additional information to the NFT when they mint it. This information may include the link to the original file or instructions about receiving the physical item.
In other words, the files or items themselves are NOT stored on the blockchains due to their size. Fundamentally, Non-Fungible Tokens operate as proof of ownership certificates. However, there is an active development of decentralized storage with the InterPlanetary File System (IPFS).

What is the InterPlanetary File System in simple words?
This peer-to-peer network allows storing and sharing data in a distributed file system similar to BitTorrent. It helps to identify specific files from the whole file pool.
