NFT makes it possible to confirm the authenticity and (alleged) ownership of digital data (and any physical objects linked to it) using digital certificates. NFT stands for Non-Fungible Tokens. It is a method of tokenizing assets.
A token is a programmable digital unit of value stored on a blockchain. There are different types of tokens, and they can represent anything from coins to stocks, from goods to loyalty points.
Tokenization is, therefore, an act of recording a digital unit of value on the blockchain. The tokens can represent different things and adhere to different rules. Popular standards (the set of rules defined by the developer on which the nature of the token depends) for tokenization are the
ERC-20 standard and the
ERC-721 standard.
These standards can be used for different types of goods. ERC20 can be utilized for replaceable tokens or fungible tokens. Fungible goods are, by definition, exchangeable. It doesn't matter which specific item you buy or sell – Euros are convertible, just like silver, gold, oil, or grain. It doesn't matter which grain or euro coin you have: every item represents the same value.
The ERC-721 standard, on the other hand, is used for non-replaceable tokens, non-fungible tokens. Non-fungible goods are therefore not replaceable. The goods are unique. Think of a silver necklace or a painting, a signed book, or a football picture with the signature of the football player. It cannot be replaced by the unique creativity it has, or represented, or precisely by the unique signature it bears. The value is not in the item itself but in the uniqueness and authenticity it represents.
Goods tokenized with an NFT are thus digitally guaranteed uniqueness and authenticity. The NFT contains a cryptographic hash function. The blockchain can check the code so that the unique identity and ownership of the NFT can be determined.
The idea behind the NFT is that of scarcity. Non-replaceable, digital works can thus be traded with the notion that the value of the items lies in their uniqueness. Anyone can still trade the football tickets or copy the painting, but there is one unique digital version of that. The rarer the NFT, the more value. So just like the signature on the football ticket, the NFT itself is the signature of the content creator, making it scarce, unique, and valuable. At least, that's the thought.
Copied Digital Files
And that brings a lot of new possibilities that, at least in theory, can trigger a new revolution. Not just for registered property, real estate, or shares. But for basically every possible asset or digital file.
For example, digital files are, in principle, infinitely reproducible. A song, movie, image, in-game items, piece of text, or source code: it can all be copied. But who owns that digital data? Does the digital file belong to one owner, and the rest is an illegal copy of it? Or is it all self-contained data, owned by everyone? And what if you want to transfer a digital file – how do you know that the transferring party owns it and is authorized to transfer it?
This cannot be said with 100% certainty based on the digital file itself. This can be met with NFTs. NFTs can make digital files artificially scarce. A digital file can become 'unique and make it non-replaceable.
NFT Against Counterfeit Goods
But NFTs can also offer a solution in the offline world. Artworks, designer clothes, unique sneakers, collectibles. NFTs can be used to assess whether it is genuine or counterfeit. It infringes on trademark rights, design rights, copyrights, or patent rights.
Does an NFT provide a digital certificate of ownership and authenticity or just a receipt?
NFTs thus offer a kind of digital certificate based on the blockchain. Digital and physical objects can be verified for authenticity and ownership.
However, an NFT is not a digital title for the original. It does not give any actual ownership claim. It's just a receipt, a digital receipt, that you own a signed version of something—not the real thing itself. So while the idea behind the NFT is scarcity, this is just an illusory scarcity.
After all, whoever is the creator of the digital file tokenized in NFT might also make more copies of the work and sell these 'unique' versions. Although it dilutes the value of the NFT, if that copy has already been sold, it has no consequences for the original maker. In other words, more unique versions of the same resource can be created.
Anyone could tokenize a Picasso painting or an expensive pair of sneakers that you don't own with NFT. That doesn't mean you own the tokenized object in question. You only hold the digital certificate that you have linked to it. In short: perhaps you are not buying a unique item, but only a unique receipt.
Nevertheless, this offers countless possibilities. Not only for art, collectibles, or registered property but in fact, everything can be recorded digitally. NFT can also provide a particularly welcome solution for counterfeiting by rightsholders.
NFT Platforms
However, NFTs are not without risks. NFTs can be purchased and created online through platforms such as
OpenSea, Rarible, SuperRare, Mintable, ThetaDrop, and KnownOrigin. As a holder of an NFT, you depend on the relevant platform for the sale of products. This is immediately referred to as vendor lock-in.
And that brings me to another problem. The networks are technical infrastructures and prone to hackers, corruption, scams, bugs, and human error. As with cryptocurrencies, various possible problems can lead to losing access to the NFT.
What if an NFT platform is "flat"? What if an NFT company steals your Ethereum and cannot be found? What if you save an NFT incorrectly? What if you have lost access to your wallet? What if your wallet has been hacked?
Moreover, the question is how rare a (digital) object actually is since it may be the only NFT on one blockchain but can also be tokenized on another blockchain.
Ownership Verification
If you ask me, there are still some challenges to making NFTs commonplace. As far as I'm concerned, one of the most important issues is verifying ownership. Based on the NFT alone, you cannot be sure that the object actually belongs to the person offering it on the aforementioned NFT platforms (or elsewhere).
I expect there will still be some claims related to the healing of objects by linking them to an NFT without that party actually being the owner of the actual object.
Money Laundering
Another problem, which also plays a role with cryptocurrency, is money laundering. The amount obtained can be justified by creating an NFT and buying or selling it with an anonymous wallet, despite the fact that the NFT was made with black money.
In short: NFTs seem like an excellent new development. However, I still see some legal snags before they could actually become commonplace.
