Non-Fungible Token (NFT): What It Is, How It Works, and How to Buy or Create One

Non-fungible tokens (NFTs) are digital assets that have been tokenized using blockchain technology. Each NFT is assigned a unique ID and metadata that distinguish it from any other token.

NFTs can be bought, sold, or traded for money, cryptocurrency, or even other NFTs–it all depends on how the market and collectors value them. For example, someone could create an NFT of a banana image. One person might pay millions for it, while someone else might say it’s worthless.

Cryptocurrencies are also tokens, but the main difference is that two crypto coins on the same blockchain are interchangeable–they’re fungible. Two NFTs on the same blockchain might look identical, but they’re not interchangeable.

Key Takeaways

• NFTs (non-fungible tokens) are unique cryptographic tokens that live on a blockchain and can’t be duplicated.
  
• They can represent digital or real-world items, like art or real estate.
  
• “Tokenizing” these assets makes buying, selling, and trading more efficient and reduces the risk of fraud.
  
• NFTs can also represent identity data, ownership rights, and other valuable assets.
  
• Interest in NFTs surged as public awareness grew, but their popularity has since declined.
  

The History of NFTs

NFTs were created long before they gained mainstream popularity. Reportedly, the first-ever NFT was “Quantum,” developed and tokenized by Kevin McCoy in 2014 on Namecoin, then minted and sold in 2021 on Ethereum.

NFTs are built on the ERC-721 standard (Ethereum Request for Comment #721), which defines how ownership is transferred, how transactions are verified, and how apps handle secure transfers. ERC-1155, approved six months later, improves on ERC-721 by combining multiple NFTs into a single contract, which helps cut transaction costs.

In March 2021, a collection of digital artworks by Beeple sold for over $69 million. The piece was a collage of his first 5,000 days of work and set a record as the most expensive digital art sale at the time.

$69 million.

How NFTs Work

NFTs are created through a process called “minting,” where the NFT’s information is recorded on the blockchain. In simple terms, minting involves creating a new block, validating the NFT’s data, and closing the block.

Smart contracts are often part of this process. They assign ownership and manage the transfer of NFTs.

Each minted NFT is given a unique identifier tied to a specific blockchain address. Every NFT has a publicly visible owner (i.e., the address that holds it). Even if you mint 5,000 NFTs of the same item (such as movie tickets), each one has a unique ID and can be distinguished from the others.

Just like traditional NFTs, Bitcoin Ordinals can be bought, sold, and traded. The difference is that NFTs tag art or music files with serial numbers, while Bitcoin Ordinals assign IDs to individual satoshis – the most minor units on the Bitcoin blockchain.

Blockchain and Fungibility

Like physical cash, cryptocurrencies are typically fungible. That means you can trade one for another of equal value. One bitcoin is always worth another bitcoin on the same exchange, just like every US dollar bill is worth $1.

NFTs flip that concept. They’re designed to be one-of-a-kind, making it impossible to say one NFT is “equal” to another. They represent unique digital assets and are often compared to digital passports–each NFT includes non-transferable, unique ID data that makes it stand out.

NFTs can also be composable: you can combine one NFT with another to create a third, unique token.

Examples of NFTs

The best-known use of NFTs is CryptoKitties. Launched in November 2017, these are digital cat images with unique blockchain IDs. Every kitty is different and has its price. They can “breed” to create offspring with new traits and valuations.

Within just weeks of its launch, CryptoKitties built a considerable fan base. Users spent over $20 million worth of Ether buying, feeding, and breeding these virtual pets. Some collectors spent more than $100,000.

More recently, the Bored Ape Yacht Club made headlines with sky-high prices, celebrity attention, and high-profile NFT thefts.

Early NFT markets focused on digital art and collectibles. Today, the scene has expanded. On marketplaces like OpenSea, NFTs now span across categories like:

• Photography: Artists tokenize their photos and sell full or partial ownership. For example, OpenSea user “erubes1” sells ocean and surfing photos from the “Ocean Intersection” series.
  
• Sports: Digital collectibles featuring athletes and sports moments.
  
• Trading Cards: Tokenized versions of collectible cards–some are playable in games, others are purely for collecting.
  
• Utility: NFTs that unlock benefits or grant membership access.
  
• Virtual Worlds: Digital real estate, wearable avatars, and more.
  
• Art: Everything from pixel pieces to abstract designs.
  
• Collectibles: Famous projects like Bored Ape Yacht Club, CryptoPunks, and Pudgy Pandas.
  
• Domains: NFTs that represent ownership of domain names.
  
• Music: Artists tokenize songs and grant buyers specific rights.
  

NFTs Featuring Ukraine’s President Volodymyr Zelenskyy

In a powerful collaboration between Ukrainian tech innovators and blockchain creators, a one-of-a-kind NFT collection featuring President Volodymyr Zelenskyy was born. This project blends art, tech, and charity with a real-life heroic narrative.

The #ActLikeZelensky collection features 100 unique NFTs showcasing Zelenskyy in various roles – from a military leader to a national icon to a Matrix-inspired figure. Each token is an artistic tribute to his defining traits.

All proceeds from these digital artworks will be used to purchase essential military equipment to support Ukrainian soldiers. The goal: raise €3 million to fund 1,000 thermal imagers, 500 vests, helmets, radios, and tactical flashlights.

All donations are managed by the Shields initiative, led by charity organizer Tetiana Kameneva from “Kurazh Bazar.” Any surplus funds will support other charities, such as LifelineForKharkiv and Come Back Alive, helping to keep Ukraine safe and strong.

The Benefits of NFTs

One of the most significant benefits of NFTs is market efficiency. Tokenizing a physical asset can streamline the buying and selling process by eliminating the need for a middleman. For example, an artist can mint their artwork and sell it directly to fans–no need for galleries or agents.

Investment Potential

NFTs can also be powerful investment tools. For example, Ernst & Young developed an NFT solution for a winery client, storing wine in a secure location and utilizing NFTs to verify its origin and authenticity.

Real estate can also be tokenized. A property can be split into sections, with each represented by a unique NFT. Say one plot is near a lake and another closer to the woods–they’d have different characteristics, prices, and NFTs.

NFTs can even represent business ownership, similar to stock shares. Shares already rely on registries that track info like shareholder name, issue date, and certificate number. Blockchain does this even better–smart contracts can automate the transfer of ownership. Sell your NFT stake, and the blockchain handles everything else.

Security

NFTs are also helpful for identity protection. When personal data is stored on the blockchain, it can’t be accessed, stolen, or used without your private keys.

NFTs can also democratize investing by allowing people to fractionalize expensive physical assets, such as art or property. Instead of needing to buy a whole painting, investors can own a share via NFT. More buyers = more demand = potentially higher value.

How to Buy NFTs

Most NFTs are purchased with Ethereum (ETH), so having a crypto wallet with some ETH is typically the first step. You can buy NFTs from major platforms like OpenSea, Rarible, or SuperRare.

Are NFTs Safe?

NFTs are generally secure because they utilize blockchain technology, which is similar to that used in cryptocurrencies. But the weak point is your private keys. If your wallet gets hacked or your device is lost, your NFT is at risk. So remember the golden rule: Not your keys, not your token. Keep your private keys safe and your NFTs will be, too.

What Does Non-Fungible Mean?

Fungibility means that one item can be swapped for another of equal value. Imagine you have three notes with identical smiley faces. Once you tokenize one, it becomes different–it’s non-fungible. The other two can still be swapped, but that NFT stands alone.

Conclusion

NFTs take the basic idea of cryptocurrency and elevate it. Financial systems today handle a wide range of assets–from real estate to art–and NFTs provide a new way to represent them digitally.

Sure, representing physical items in digital form isn’t new. Neither is using unique identifiers. But when combined with secure blockchain tech, smart contracts, and automation, NFTs become a game-changer.
