The question, what are NFTs? is one that continues to be asked by creatives around the world. Even as non-fungible tokens become more widely used and as the value of these tokens rise and fall, we continue to ask what is an NFT? Below I'll explain exactly what NFTs are, what NFTs are used for and how you can create NFT art. 

What began as an experiment in new technology and then a way for artists to take ownership of their work and control their value, has now been joined by major brands and celebrities who have embraced NFTs. The early adopters include Beeple – who set an NFT artwork auction record – as well as CryptoPunks and Bored Ape Yacht Club, but now includes Nike, Disney and the world's most prominent galleries. Game producer Square Enix has even sold off Tomb Raider to fund its NFT business. 

Answering the question, 'what are NFTs?' is actually the easy part: non-fungible tokens are a way of registering a one-of-a-kind image, video, or any form of digital, or indeed, physical item on a blockchain. It's decentralised and open to scrutiny. 

What are NFTs? remains a big question

I certainly don't blame you if you are still confused by what NFTs are or can be used for. Below I'll answer the question what are NFTs? and also touch on how they can be used by creative professionals. If you already own an NFT or two, then take a look at my pick of the best NFT displays to see how to view them in style.

Once you're clued up, you're ready to read the rest of our series of pieces on the world of NFTs. We have articles on the best NFT games and on the best NFT crypto for creatives. If you decide to venture into making NFTs of your own, see our guides to how to make and sell an NFT. NFTs also link into the metaverse and you can see how the two work together in projects such as Butcher Billy's inspired retro Atari posters.

You can also discover more in my feature, NFT meanings, slang and terms: all you need to know, which covers all of the terms around non-fungible tokens. Below I'm skim over the key points, then go into more detail about how NFTs work and more.

NFTs: everything you need to know

What are NFTs?

NFTs are designed as way for digital files to be secured in a way that ensure ownership and create scarcity. Like physical art an NFT can be sold but the artist can retain the copyright, or they can offer it to the buyer, or decide the on a percentage of secondary sales an owner can have.

What are NFTs used for?

Essentially, NFTs can represent any form of digital file, whether that's a jpeg of a piece of art, a video, or even real estate. Turning these files into 'tokens' and securing them on a blockchain make buying, selling and trading these files efficient and reduce fraud. 

How do NFTs and crypto connect?

NFTs are also called non-fungible tokens, and they are blockchain-held tokens that represent a unique asset – whether physical or digital. NFTs are secured on cryptocurrency blockchains, trading using Ethereum, Solana, Wax and other tokens. This means they are tied to the ebb and flow of cryptocurrency values, which is a positive and a negative.

Are NFTs legit?

NFTs are absolutely 'legit' but the term and use is so broad that you may stumble across scams and schemes that aren't. It's always a good idea to do your research, never accept free NFTs and if something sounds too good to be true it's best avoided.

Why do people buy NFTs?

People buy NFTs for many reasons. Some view non-fungible tokens as assets to collect and trade, they see them as investments. Others just love the art or the technology behind NFTs and like to experiment with how it can be used. More and more people are now seeing NFTs as a way to launch products, raise funding and give a voice to marginalised communities. There's a sense NFTs can unlock a new kind of democracy.

What are the best ways to make money from NFTs?

There are many ways to make money from NFTs, if that's your goal. Some key ways are listed below:

1. Play-to-Earn games: these new kind of games enable you to own the assets you earn or unlock in a game. You can collect and sell these NFTs within a game's store or on a marketplace.

2. Collecting: many people collect NFTs, spotting new projects and 'HODLing' until their values increase (they can also decrease).

3. Flipping NFTS: I wouldn't recommend this but some people like to buy NFTs for the purpose of selling them at a higher price. It's risky.

4. Investing in new NFTs: if you're serious about getting into NFTs you'll want to find projects you like and get in early. Often you can be involved in the Discord community and get on the 'whitelist'.

5. Create your own NFT: the success of NFTs is that anyone with a computer can create one, and even an NFT collection a project to fund other a project. NFTs can now even be created for free, though this comes with restrictions. 

Where can I buy and sell an NFT?

The most common way of buying and selling a non-fungible token is on an NFT marketplace, these are auction platforms created specifically to showcase NFTs. The most popular ones are OpenSea, Rarible, SuperRare, Nifty Gateway, Magic Eden and Foundation.

Should I invest in an NFT?

This is a personal question. NFTs can increase and decrease in value, and not all NFT projects are designed to make you money (some are created to raise money for charity, for example). Also, just because a piece of art has been tokenised doesn't mean it will be valuable. Do your research, and ask questions, such as who is behind the project, what will you actually own, and how can the NFT used?

Are NFTs a pyramid scheme?

Critics would say yes, and there have been dodgy projects and schemes that have fallen apart and left buyers with nothing. But, many NFTs are fine and there are good artists creating in this space. In recent months NFTs have evolved from simply being about ways to make investors money to projects with 'utility' – longterm uses in the metaverse and in real life. 

Who's buying NFTs?

Millennials appear to be the largest group buying NFTs, while Gen-X and Gen-Z are coming in close behind. Older generations are staying clear, for now. There are also a growing linear art and corporate communities that are picking up NFTs as investments are showcasing them in the receptions of offices and hotels.

NFTs: what are NFTs, exactly?

New NFT projects are releasing all the time, such as model Bella Hadid who is creating a global project (Image credit: Bella Hadid / Cy-B3lla)

NFT stands for a non-fungible token, which means that hidden in those quirky artworks, there's a unique and non-interchangeable unit of data stored on a digital ledger using blockchain technology to establish proof of ownership. Essential the same, or similar technology used for cryptocurrencies like bitcoin and ether is used to guarantee the uniqueness of each NFT and to prove who owns it. 

Unlike a unit of bitcoin, however, each NFT is completely unique, so it can't be exchanged like-for-like. The file stores extra information that elevates it above pure currency and brings it into the realm of, well, anything, really. As a result, NFTs have become collectable digital assets that hold value, just like how physical art holds value.

Any kind of easily reproduced digital file can be stored as an NFT in order to identify the original copy. The NFTs you're most likely to have seen or read about tend be minted from trippy futuristic motion artworks, NFTs can be made from any kind of photography, art, music or video file. Even tweets and memes have been made into NFTs. To help, we've outlined the NFT trends for 2022.

Essentially, you can make NFTs from almost anything unique that can be stored digitally and holds value. They're like any other collector's item, like a painting or a vintage action figure, but instead of buying a physical item, you're instead paying for a file and proof that you own the original copy. Read about the Bella Hadid NFT project to see how non-fungible tokens can reach a global audience.

NFTs: how do NFTs work?

The unique identity and ownership of an NFT is verifiable via the blockchain ledger. They were first launched on the Ethereum blockchain, but other blockchains including FLOW and Bitcoin Cash now also support them. Read my guide titled 'NFT crypto, which is best?' to get a lowdown on what's what.

Whether the original file is a JPG, MP3, GIF or anything else, the NFT that identifies its ownership can be bought and sold just like any other type of art – and, like with physical art, the price is largely set by market demand.

If you wandered into a gift shop of an art gallery, you'd find a number of replicated prints of famous masterpieces, well there are some NFTs that act the same way. There are parts of the blockchain that are totally valid, but they wouldn't hold the same value as the original. 

NFTs will most likely come with a license to the digital asset it points to, but this doesn't automatically confer copyright ownership. The copyright owner may reproduce work and the NFT owner gains no royalties. Artist Chris Petrocchi explains secondary sales and royalties in his video tutorial on how to create NFT art.

Creating NFTs isn't as difficult as you may think, either. We have a guide to to how to make and sell an NFT that is well-worth a read, and I have put together a tutorial on how to create an NFT for free, which means you can get started in the process without needing to spend any money.

NFTs: where can I buy an NFT?

What are NFTs? Creating your first NFT

NFTs are just about the art, the value is held in the contract they represent, such as Fear City broader project (Image credit: Stephen Bliss)

Don't go thinking you've hacked the system and become a millionaire by right-clicking and saving the image of Beeple's Everydays – The first 5000 days. That's just what NFT's are not. The image associated with an NFT is simply a copy, in JPG form of the original work; it's a 'story' that enables our brains to understand a non-fungible token's smart contract, the thing you're really buying. For example, former-GTA artist Stephen Bliss' illustrations for his Fear City NFT are wonderful but it's the access to the Fear City project that is valuable.

If you do want to look into buying NFTs, they can be bought on a variety of platforms depending on what you want to buy (for example, if you want to buy baseball cards you're best heading to a site like digitaltradingcards (opens in new tab), while other marketplaces sell more general pieces). 

You'll need a wallet specific to the platform you're buying on and you'll need to fill that wallet with cryptocurrency. As the record sale of Beeple's Everydays – The first 5,000 Days at Christie's proved, NFTs are hitting more mainstream auction houses, too, so these also are worth watching out for. In case you missed it, that Beeple piece went for $69.3 million.

Because of the high demand for many types of NFT, they are often released as 'drops', much like with events, when batches of tickets are often released at different times). We go into more detail in our guide to NFT drops. This means a frenzied rush of eager buyers when the drop starts, so you'll need to be registered and have your wallet topped up and ready to spend.

The sites listed below are just some of those that sell NFTs, and some such as rising Magic Eden marketplace specialise in the newer, more environmentally friendly Solana blockchain. We go deeper to this in our guide to NFT marketplaces.

NFTs: NFT games and gaming

NFTs are also changing how games are played and made. Players can buy characters or cards in an NFT game like Axie infinity or Gods Unchained and develop their heroes, the more unique they become the more valuable they are. Mainstream developers such as Ubisoft and Sega have big NFT plans, and there's even a Final Fantasy VII NFT planned for next year.

This play-to-earn model is new to gaming, and NFTs are leading the way. New games are incorporating more traditional ways to play, and some games are now blending play-to-earn with free-to-play. To discover more about NFTs and games, read my guide to everything you need to know about NFT gaming.

NFTs are also making waves as in-game purchases in video games (much to the delight of parents everywhere, we're sure). These assets can be bought and sold by players, and include playable assets like unique swords, skins or avatars.

Presently there's a struggle in gaming between NFT developers and traditional gamers. After the fiasco of loot boxes and expensive micro-transactions gamers are hesitant to embrace market forces in games, as it could lead to more expensive experiences. Or it could lead to a levelling playing field and greater access for gamers to make or invest in games. The future is, ahem, what you make it. 

I look at this in detail in our guide to what this all means for NFT gamers and the future of games. Below I've listed some of the biggest NFT games currently being played.

5 of the best NFT games

1. Axie Infinity (opens in new tab): it's Pokémon with NFTs as you breed and collect adorable creatures while exploring a unique world

2. The Sandbox (opens in new tab): think of this one as Minecraft on a blockchain, where everything you create you own, including games and worlds

3. Gods Unchained (opens in new tab): this card battle and collecting game has been developed by former Magic: The Gathering designers

4. Splinterlands (opens in new tab): another card battle game, this one places an emphasis on speed.

5. CryptoKitties (opens in new tab): collect and breed cute cats, and join with other players to solve puzzles

NFTs: who uses NFTs?

What are NFTs? Varvara Alay and Flower Girls represents NFT art

NFTs are having a moment among artists, gamers and brands across all kinds of sectors. In fact, it seems every day brings a new player to the NFT marketplace. For artists, stepping into the NFT space adds another possibility for selling art, and provides fans with a way to support it.

Celebrities are also getting involved, either as investing as collectors, or creating their own NFTs (or having them created for them by artists). Some of these celebs are using their new NFTs in media projects, while Madonna made headlines when she partnered with Beeple to create her Mother of Creation NFT project.

It would be expected that work by well-known artists would fetch big bucks as NFTs, something an anonymous group of 'art enthusiasts' relied upon when they burned an original Banksy (opens in new tab) in order to increase the value of an NFT. However, some sales are still eye-popping for the prices they reach. When Pak's NFT Artwork 'The Merge' sold for $91.8 million in December (he actually sold shares in the artwork), it was the third-highest price ever fetched by the work of a living artist.

Many new artists and traditional artists coming into NFTs are using the technology to affect change. The artist Nina Chanel Abney's bold NFT collection expresses her views on diversity and develop her style. The Flower Girls NFT by Varvara Alay explores the artistic boundaries of non-fungible tokens and the artist uses money made from her art to fund children's art projects and support female artists.

NFTs are becoming an attractive revenue stream for brands, and we've seen all kinds of companies jumping on the bandwagon. Nike bought NFT studio RTFKT and has since made headlines from selling collectible and customisable non-fungible tokens of Nike sneakers. 

Nike has been joined by brands as diverse as Adidas, Coachella, the Super Bowl and Dolce & Gabanna, and while these companies are using NFTs in fairly standard ways, to offer collectible digital wearables and items, some companies are trying new ideas. For example, fragrance maker Byredo has partnered with RTFKT to create scents to use in the metaverse. These are both digital and in real life scents.

Even the US basketball league NBA has got involved. NBA Top Shot (opens in new tab) is a way of selling digital collectables in the form of trading cards embedded with iconic basketball moments. With a plan to add virtual jewellery, accessories and clothing that can be used across social media, the NBA is aiming to expand this revenue stream as far as it can go.

Musicians are also selling the rights and originals of their work, as well as short videos to clips of their music. In recent times this has even been a Beatles NFT auction that saw rare memorabilia, including John Lennon's famous Help! cape or the Beatles' Afghan coat from Magical Mystery Tour, go up for sale (as NFTs).

NFTs are quickly become an excellent way for musicians and bands to launch their albums and connect in meaningful ways with their audiences. There are some dedicated NFT music marketplaces (opens in new tab) to track, too.

You can even buy digital real estate and 3D assets like furniture as NFTs. A'digital home' sold for an eye-watering $500,000. 'Mars House', designed by Toronto artist Krista Kim (opens in new tab), was described by digital art marketplace SuperRare (opens in new tab) as the 'first digital house in the world'. Created with the help of an architect and video game software, the owner will be able to explore the mansion on Mars using virtual reality and can sunbathe outside the house (in the Mars atmosphere).

NFTs: Why are NFTs controversial?

What are NFTs? How to make and sell an NFT, using Ethereum as represented by a dog illustration

NFTs are controversial, mostly because of the environmental impact from legacy blockchains like Ethereum (Image credit: ethereum.org)

There's a lot of money being made in the NFT market, but you'll have heard there's also great controversy, not least due to the impact on climate. The creation of blockchain assets, NFTs included, uses a large amount of computing power – and so a huge amount of energy. Some are worried about the very real impact the craze could have on the environment. 

Artists can help, by making efforts to create carbon-neutral artwork. But the problem goes deeper, because of the way blockchain works. Ethereum, Bitcoin and the like are built on a 'proof-of-work' system (like a complex series of puzzles) to keep the financial records of users secure. And this system uses an incredible amount of energy.

ArtStation was so worried about the impact on the climate that it recently backtracked on its decision to sell NFTs after a massive backlash. There are organisations trying to make a difference. Check out what Blockchain for Climate (opens in new tab) is doing to improve the situation.

This is getting better. New blockchains such as Palm, Flow, and Wax are low energy and carbon neutral, and offset emissions by planting trees. The Polygon token, for example, states it costs the same amount of energy to mint am NFT on its blockchain as it does to send three emails. 

Many voices in the art and design community are also angry that NFTs are changing hands for such astronomical sums of money, and it's often not going to the artist. Given that NFTs were originally created as a way of giving control (opens in new tab) by asserting digital ownership, the idea that they are becoming increasingly elitist is causing tension. The buy-in fees are prohibitive for many, and the cost to actually buy one means the marketplace is becoming something of a playground for the super-rich.

But, again, times are changing. More and more artists are turning to the Solana blockchain to create NFTs, as this is carbon neutral and has lower 'gas' fees – the cost of registering the NFT. 

NFTs: Can anyone make an NFT?

Technically, anyone can create a piece of art, turn it into an NFT on the blockchain (a process called 'minting') and put it up for sale on a marketplace of choice. You can even attach a commission to the file, which will pay you every time someone buys the piece through a resale. If you are new to NFTs, then read my guide to NFT tips for beginners where I outline some of the big mistakes to avoid.

Much like when buying NFTs, you need to have a wallet set up, and it needs to be stuffed full of cryptocurrency. Though this hurdle is now being dismantled as NFT marketplaces and projects are enabling people to buy NFTs using fiat currency via credit and debit cards. For example, Ebay has acquired NFT marketplace KnownOrigin and is developing its non-fungible token content, enabling buyers and sellers to use credit and debit cards.

The hidden fees can be prohibitively astronomical, with sites charging a 'gas' fee for every sale (the price for the energy it takes to complete the transaction), alongside a fee for selling and buying. You also need to take into account conversion fees and fluctuations in price depending on the time of day. 

All this means that the fees can often add up to a lot more than the price you get for selling the NFT. It is also, however, now easier to create an NFT for free but placing the fees on the buyer and not the creator.

NFTs: has the NFT bubble burst?

Are NFTs over? Not quite, according to experts (Image credit: Vanity Fair)

It's been widely reported that the NFT bubble has slowed down, if not burst, and we're in the midst of a 'Crypto Winter'. Sales of NFTs dropped by 92% year on year, but that headline doesn't tell the full story. Despite news of the decline many tech and media brands are more keen than ever to embrace NFTs. 

Social media giant Meta has revealed it will continue with plans to integrate the blockchains Ethereum, Polygon, Solana and Flow into Instagram and now Facebook – and users won't be charged. Likewise, Square Enix, Ubisoft and even Epic Games have all committed to NFTs as being a part of their future. A recent Vanity Fair NFT cover is very strange but also shows there's still an appetite for this technology.

For collectors it means NFTs have become cheaper, what would have cost $280 six months ago is now around $50. This represents a good time to search out new and interesting projects. For creators the situation is not great, however, as some artists have worked a year on an NFT project, such as Fear City, to find they launch at the wrong time.

Generally hose passionate about NFTs are still keen and see the downturn as a blip, and something caused by external pressures such as high inflation. Many compare the state-of-affairs to the dot.com bubble of the late 1990s, and while many websites closed it also gave rise to good businesses, such as Amazon, Facebook and Google.

Whether or not NFTs are here to stay, for the moment they are making some people money and they're creating new possibilities for digital art. We would, however, advise caution and careful consideration of which platforms to use. And if you want to get creating, make sure you've got one of the best laptops for drawing or one of the best laptops for video editing. A top drawing tablet is also advisable.
