For many years, the internet has allowed us to copy almost anything within seconds. An image, music, a video or another digital file can easily be downloaded, saved and shared further. For that reason, it was long difficult to establish true uniqueness or ownership of digital objects online. NFTs introduced the idea that even on the internet there can be something unique, verifiable and technologically distinguishable from an ordinary copy.

Within a few years, NFTs became one of the best-known concepts connected with cryptocurrencies and blockchain. For some people they represented a revolution in digital ownership; for others, mainly a speculative bubble. Regardless of how we view them, one thing is certain: NFTs opened a debate about what ownership, value and trading in digital assets may look like in a new internet environment.

From a digital copy to digital ownership

NFT stands for non-fungible token. The word "non-fungible" is the key point here. With ordinary money, or for example with Bitcoin, we do not care which exact unit we own, because the units are mutually interchangeable. With an NFT it is different. Each token is unique, has its own properties, identifier and metadata that distinguish it from the others. Thanks to this, it can represent a specific digital or physical object and makes it possible to prove publicly who owns it.

This uniqueness introduced something digital assets had long lacked: scarcity. On the internet, anyone can still download a copy of an image or video, but an NFT makes it possible to prove who owns the original token associated with that work. In other words, an NFT does not prevent the content itself from being copied, but it introduces a system in which ownership of a specific digital asset can be verified.

How it all began

The first known NFT is often considered to be the project Quantum, created by Kevin McCoy back in 2014. For a long time, however, the concept attracted little public attention, and it remained more of a marginal technological curiosity.

An important shift came in 2017, when projects began to appear that showed NFTs in a more practical and visible form. Among the best known were CryptoPunks, a collection of 10,000 unique pixel characters on the Ethereum blockchain, which later became one of the symbols of the entire NFT market. We will discuss CryptoPunks in more detail in the next part of the article.

The CryptoKitties project also appeared in 2017. These were digital collectible cats, each of which had its own unique traits. Users could buy, sell and "breed" them, creating additional unique variants.

This project showed a wider audience that blockchain does not have to be used only for transferring cryptocurrencies, but also for owning unique digital objects. Later, a much broader market began to form around NFTs, expanding into art, gaming, memberships, and digital identity.

What an NFT represents

An NFT is essentially a digital record on a blockchain that confirms ownership of a specific token. That token can represent, for example, digital art, a collectible item, an in-game item, a ticket, a certificate, membership access or even certain real-world assets converted into digital form.

It is important to understand that an NFT is not merely an "image from the internet", but a unique token linked to a specific blockchain address. Anyone can publicly verify ownership.

It is also necessary to understand what an NFT does not mean. When someone buys an NFT connected with a particular work, it does not automatically mean that they receive all copyright rights to that content. That depends on what rights the author or project assigns to the specific token.

An NFT therefore typically confirms ownership of the token, not automatically full control over the work itself in the sense of copyright. This is one of the things that is very often misunderstood.

This is where NFTs derive much of their significance. An NFT makes it possible to create digital proof of ownership or authenticity that can be easily verified.

How NFTs work

An NFT is created through a process called minting, meaning the creation and registration of the NFT on a blockchain. During this process, a unique token is created for digital content such as an image, video or game item. The token is then recorded on the blockchain, where its origin and owner can be traced.

NFTs operate through smart contracts that define ownership, transfers and other rules. It defines the basic rules: who created the NFT, who owns it, how it can be transferred and what properties it has. Each NFT therefore has its own identifier and is assigned to a specific blockchain address, meaning the digital address of the owner's wallet. This ensures that it is distinguishable from other tokens and that its ownership can be publicly verified.

NFTs are most often associated with the Ethereum blockchain, where technical standards such as ERC-721 or ERC-1155 are used for their operation. For an ordinary reader, these can be understood simply as a set of rules that allow wallets, marketplaces and applications to know how to work with NFTs. Thanks to these shared rules, NFTs can be created, bought, sold and used across different services.

Why NFTs attracted so much attention

One of the main reasons NFTs gained so much attention was the possibility for creators to offer their works or digital products directly to an audience without some traditional intermediaries. Thanks to this technology, they could reach a global market while setting the terms under which their work would later be resold or used. NFTs therefore brought a new way to work with digital ownership, content distribution and trading in certain types of assets.

For investors and collectors, the main attraction was that NFTs created a new type of digital scarcity. People could suddenly own something that was publicly verifiable, limited and transferable. It was precisely the combination of technology, collecting, speculation and a new type of digital ownership that brought NFTs to the center of attention of the entire cryptocurrency market.

Limits and problems of NFTs

As with other new technologies, however, it soon became clear that NFTs also have weaknesses. One of the biggest limitations is the fact that the digital content itself can still be copied very easily. Anyone can download and save an image, video or other file just as easily as ordinary internet content. An NFT therefore does not prevent someone else from having the same thing in their gallery or on their device.

The difference is that only the owner of the original NFT has blockchain-verifiable proof that they own the original token. Someone who only copies the content may have the copy, but they do not have verifiable proof of ownership of the original.

This can be compared to a counterfeit luxury watch. At first glance it may look similar, and other people may not even notice the difference, but for the owner of the original, real ownership has a different value from a mere imitation. This human factor - the importance of originality, ownership and the feeling that one holds the "real piece" - is one of the factors that gives NFTs value.

Another weakness is security risk. Problems around NFTs often do not relate so much to the blockchain itself, but rather to phishing, vulnerabilities in smart contracts or user mistakes, for example when handling private keys.

Limited liquidity can also be a challenge. An NFT is usually much more specific than an ordinary cryptocurrency, and if interest in a particular collection or type of token fades, it may be difficult to find a buyer.

It also became clear that a large part of the market was driven by speculation. Many people bought NFTs not because they wanted to own or use them in the long term, but because they expected a rapid increase in price. Once interest cooled, a significant part of the market lost momentum. That does not mean the technology itself lost its significance. Rather, it began to become clearer where NFTs have real use and where they were mainly a short-term wave of enthusiasm.

CryptoPunks Turned Into Tiffany Jewelry

One of the most interesting moments when the world of NFTs connected with the real world was the NFTiff project by Tiffany & Co. In August 2022, Tiffany offered owners of NFTs from the CryptoPunks collection the opportunity to turn their digital avatar into a real luxury jewel. CryptoPunks are among the oldest and most influential NFT projects on Ethereum: the collection was created back in 2017 and contains 10,000 unique pixel characters. Owners could buy a special NFTiff Pass, which gave them access to the production of a custom pendant inspired by their specific Punk.

Each such jewel was made from 18-carat yellow or rose gold, contained at least 30 gemstones, and Tiffany tried to translate the colors and features of the original NFT into physical form as faithfully as possible. The package included not only the pendant itself, but also a digital NFT version of the resulting jewel and a certificate of authenticity. The entire project was limited to 250 pieces, with the price of one NFTiff set at 30 ETH, and according to available information the collection sold out in about 22 minutes.

It is also interesting that this was not a completely classic "Tiffany x official CryptoPunks" collaboration in the traditional sense. The project was based on the fact that, after the transfer of rights under Yuga Labs, CryptoPunks holders gained the ability to use their Punks commercially.

Tiffany was therefore not simply taking someone else's images from the internet, but working with a model in which digital ownership gained a commercial and physical form. This is what matters about the whole project: it shows that an NFT does not have to be only a speculative digital image, but can also function as the basis for a real product, a brand and verifiable ownership.

This is exactly where the possible meaning of NFTs in the real world becomes visible. At the moment when the virtual turns into something physical, while still carrying a reference to something virtual, a new type of value emerges. In such a case, the NFT is no longer only an image on a screen, but becomes digital proof of origin, a ticket to a physical product and a bridge between online identity and the real world. The Tiffany project showed that blockchain can function in luxury goods not only as a technological curiosity, but also as a tool of authenticity, exclusivity and the connection of digital culture with traditional craftsmanship.

Artist Damien Hirst and The Currency

Another interesting NFT project that explored the relationship between digital and physical ownership was The Currency by British artist Damien Hirst. The project was created in cooperation with the HENI platform and was based on a simple but powerful idea: for each of the 10,000 NFTs there also existed 10,000 corresponding physical works on paper. It was therefore not just a sale of digital art, but an experiment exploring what people actually consider more valuable: an original they can hold in their hands, or its existence on the blockchain.

The works themselves were based on Hirst's famous aesthetic of colored dots. Each physical piece was unique, created on handmade paper, numbered, named, signed on the back and equipped with elements verifying authenticity, such as a watermark, a microdot and a hologram with the artist's likeness. The NFT version then functioned as the digital twin of that specific work. In this way, Hirst suggested that the value of art does not have to be tied only to material, but also to trust, origin and the method of recording ownership.

The project launched in July 2021 and each token sold for 2,000 dollars. The key point, however, was that after a certain time buyers had to choose only one option: either keep the NFT and have the physical artwork destroyed, or claim the physical original, in which case their NFT would cease to exist. This choice was the core of the entire project. Hirst effectively turned the debate about the value of digital art into a concrete decision with real consequences. At the end of this process, 5,149 collectors chose the physical work and 4,851 kept the NFT.

In September 2022 came perhaps the most symbolic part of the whole project. At The Currency exhibition, the physical works whose owners had chosen to keep only the digital version began to be burned one by one. Damien Hirst personally started the process by burning his own works, and the conceptual experiment suddenly became a powerful gesture about what we consider an "original" today. The Currency thus showed that an NFT does not have to be just a digital image without broader meaning, but can function as a tool that redefines the relationship between ownership, authenticity and artistic value.

This project clearly shows how interesting the overlap of NFTs into the real world can be. It was not only that a physical object existed as an addition to a digital work. Hirst's idea was far more radical: digital art can exist physically, or only digitally, but not always both at the same time.

And precisely when the virtual becomes something physical, or when the physical remains only as a reference to something virtual, a new type of value emerges. In such a case, the NFT is not just an image on the internet, but a carrier of story, proof of ownership and a decision that has a real impact in the real world.

Bored Ape Yacht Club: when an NFT is not just an image

Another notable example is Bored Ape Yacht Club, often shortened to BAYC. It is a collection of 10,000 unique digital apes on the Ethereum blockchain, created by the company Yuga Labs.

The project launched in 2021 and from the beginning it was not built only on the idea that a person was buying an image. Each ape also functioned as membership in a private club that offered its holders access to a community, further projects, merchandise drops and physical events. This is exactly what distinguished Bored Ape from many other NFT collections: it was not selling only a digital file, but also a sense of belonging, status and entry into a certain world.

Something else was also important about Bored Ape Yacht Club: according to the official terms, the holder owned not only the token in a wallet, but also the image of their ape, which opened the way for broader commercial use.

In other words, the NFT here did not function only as a digital collectible item, but also as an asset that could be developed further. This represented a strong shift from the common perception of NFTs. Suddenly it was not only an image on a profile, but a digital identity, a brand and property that could live beyond the blockchain.

The growth of the project itself was exceptionally fast. At launch, one ape cost 0.08 ETH and the collection sold out in approximately 12 hours. Already in 2021, BAYC became a symbol of the NFT boom and one of the moments that showed how quickly an internet trend could become a cultural and investment phenomenon. Major auctions confirmed this as well: for example, a set of 101 Bored Ape NFTs sold at Sotheby's for more than 24 million dollars. At that moment it was already clear that the "apes" had become more than a short-term internet trend.

The most interesting aspect, however, is its overlap with the real world. Unlike the Tiffany or Damien Hirst projects, this was not primarily about turning one digital work into one physical object. With Bored Ape, the overlap was broader: the NFT became a club, a brand, a ticket to real events and also a basis for collaborations with major companies.

For example, adidas Originals, the lifestyle and streetwear division of adidas, also entered the BAYC ecosystem. It used NFTs and cooperation with Bored Ape Yacht Club as part of its metaverse strategy, meaning its effort to establish itself in virtual environments and digital communities. This clearly shows that an NFT can function as a bridge between the virtual and physical worlds in ways other than a jewel or a painting. It can turn into a community, a business and a real product that still rests on digital ownership.

That is why the "apes" are such an interesting story. They are important not only because they were expensive and famous, but because they showed a new model for how digital ownership can work. Here, the virtual does not turn only into something physical, but into something socially and commercially real. The NFT then is no longer only an image stored on a blockchain, but a ticket into a community, a symbol of identity and a tool through which a digital thing can gain real impact in everyday life. That is where their greater meaning lies.

NFTs today

Today, NFTs are generally no longer viewed as uncritically as they were during the biggest boom. The main wave of interest came in 2021 and at the beginning of 2022, when NFTs became a global phenomenon and a major topic across the cryptocurrency market. Over time, however, interest cooled significantly, and it became clear that much of the original growth had been built mainly on hype and speculation.

Today, NFTs are a smaller and more specialized part of the market, one that is not as attractive to the general public as before. Instead of simple enthusiasm, more attention is paid to the question of where the technology really makes sense. Developers are exploring practical applications, for example, in ticketing, digital identity, membership, the gaming industry and the tokenization of real-world assets.

NFTs today are therefore not only a symbol of digital images sold for high sums, but rather an example of how blockchain can work with ownership of unique things. Whether NFTs succeed in the long term will not depend only on market prices, but mainly on whether they bring real utility beyond the speculative environment.

Conclusion

NFTs represent an attempt to transfer into the digital world something that used to be common mainly in the physical world: the ability to own an original, prove its authenticity and transfer it onward easily. It is not just an image on the internet, but a unique token recorded on a blockchain that can represent a wide range of digital and real-world assets.

As with Bitcoin, many exaggerated expectations arose around NFTs, but also a technology that opened new possibilities. Perhaps NFTs will not become a revolution in all the areas people originally discussed. Even so, NFTs demonstrated that ownership in the digital world can be structured and verified in ways that were previously difficult to achieve on the internet.
