Non-fungible tokens (NFTs) are stored on blockchains, and these “great public ledgers” immutably record the existence and ownership of each token.
NFTs represent ownership of a physical or digital object. Each NFT is a cryptographic asset (a transferable digital representation designed so that it cannot be copied/duplicated) with a unique identification code and metadata (content descriptive information) that differentiates it from other tokens.
NFTs digital wallet cannot be traded with each other equally, as each token can have a different value. NFTs represent ownership of many items, including works of art, virtual collectibles, video game content items, or even plots of land.
What is the interest of NFTs?
When you purchase a product in the physical world, it is common for this product to have specific or even unique properties and to be available only in a finite number of copies. The purchase is usually accompanied by a receipt proving that it belongs to you. Sometimes just owning your product is enough to make you its owner.
Currently, the Internet does not allow users to own digital objects like one can own a physical object. The goal of NFTs with utility is to allow the same rules in the physical world to apply online so that digital assets can be rare and distinct from one another. NFT advocates also claim they provide the security of “proof of ownership” you need on the internet.
NFTs allow us to create rarity, distinction, and proof of ownership of online content. However, there are still limits to this. NFTs are unregulated and do not create legally binding contracts. It still needs to be determined whether an NFTs in apple wallet can provide the same proof of ownership as a physical receipt.
NFTs are part of a self-contained, global economy and can be sold on different NFT marketplaces, person-to-person, in exchange for cryptocurrencies. Currently, NFTs are used to represent:
- works of art ;
- collectibles such as trading cards;
- virtual objects in games, in particular, character outfits and virtual game currencies;
- music ;
- virtual lands in metaverses;
- video sequences;
- legal documents;
- real assets called “tokenized”.
However, the world of Top utility NFTs is still in its infancy. As you move towards an increasingly decentralized digital world, you can expect many other uses for NFTs. The use of NFTs also poses potential problems, such as environmental impact, security issues, and possible financial risks.
How do NFTs work?
Now that you know the basic concepts of an NFT, let’s look at how they work. No two NFTs are the same. Unique NFTs differ from cryptocurrencies, which are fungible. However, all of these digital assets are registered on blockchains. NFTs come with a series of properties that allow them to work.
Single ownership of assets
One owner only owns the vast majority of NFTs at a time, and each NFT represents a single digital or physical asset. The ownership status of an NFT is secure and traceable because it is recorded on a blockchain (the Ethereum blockchain for most NFTs).
The blockchain is a decentralized, anonymous, and non-modifiable public ledger that records transactions. NFT intelligent contracts, which are computer protocols aimed at automating an action when pre-requisite conditions are met, are stored there. In other words, the proof of ownership is immutable. No one can screenshot someone else’s NFT to claim it as their own and authentic.
You cannot lose your NFT, as it is referenced on a blockchain. Thus, NFTs are akin to digital receipts. The proof that the owner of an NFT owns the real digital or physical object is visible to all.
Ownership is managed via the unique identifier and metadata of each NFT. This is information that differs for each digital token. Each NFT has a public key and a private key. The creator of the NFT holds the public key, a certificate of authenticity that proves the origin of the NFT. The owner of the loyalty programs retail also has a corresponding private key, which serves as proof of ownership of the original. A user’s crypto wallet signature can also be used to authenticate them as the owner of an NFT.
