Cryptocurrency is one of the most well-known – but far from the only – ways to use distributed ledger technology. The real strength of blockchain emerges when it’s applied to certify uniqueness through non-fungible tokens (NFTs). In this guide, we’ll break down what NFTs are, how they’re made, and where they find real-world applications.

What Are NFT Tokens
Non-Fungible Tokens represent a new class of digital assets – each token is unique and cannot be replaced by another. That’s what sets NFTs apart from both digital and fiat currencies, which are completely interchangeable.
Here’s an easy example. Imagine you borrow $10 and are asked to return the exact same banknote. When paying back, you can hand over any $10 – the value remains the same. That’s what it means for money to be fungible.
The same logic applies to digital currencies. One Bitcoin or Ethereum token can be exchanged for another of the same kind. You could borrow 1 ETH created a month ago and repay it with 1 ETH created today – they’re identical in value.
NFTs, however, are different. Think of a football signed by a national team player. You can’t replace it with just any other ball, even if it’s the same model. That signature makes it unique.
The same goes for NFTs: they are one-of-a-kind and cannot be divided. You can split a dollar, ruble, or bitcoin into smaller units – cents, kopeks, or satoshis. But NFTs are transferred only as whole tokens.
These tokens link ownership to a particular digital item – for instance, a game character, artwork, or internet meme. Normally, if you buy something inside a game using in-game currency, that item still technically belongs to the developer and can be changed or removed. But once tokenized as an NFT, ownership is provable and permanent. Both the owner’s address and the asset’s data are recorded on the blockchain – secure and immutable.
Put simply: an NFT is a blockchain-based certificate proving ownership of a unique digital or physical asset.
A Brief History of NFTs
The idea dates back to the early Bitcoin era with projects like Colored Coins and Counterparty, which made indivisible tokens possible. A famous example was a meme – Pepe the Frog – tokenized as a digital collectible. In 2018, one Pepe NFT sold for roughly $38,500 in PepeCash.
Ethereum later became the home of NFT innovation. Larva Labs’ CryptoPunks – pixelated portraits initially given away for free – turned into sought-after digital relics. In early 2021, before ETH’s price surge, one punk sold for 100 ETH.
Then came the famous CryptoKitties: a blockchain game where you “breed” unique NFT cats. Buy two cats, produce NFT offspring. In 2018, one kitten sold for 600 ETH.
Later, games were built around existing NFTs. Wrapped Kitties let users wrap CryptoKitties as ERC-20 tokens to sell fractional exposure. CryptoCelebrities saw a Donald Trump NFT sell for $137,000.
Tokenization spread to trading cards, sports assets, domain names, and even traditional financial instruments. The next wave was digital art, and dedicated NFT marketplaces emerged.
Where Can Non-Fungible Tokens Be Used?
NFTs now span a wide range of industries – from gaming and digital art to ticketing and real estate. While cryptocurrencies act like digital money, NFTs are used to represent ownership of unique goods.
On a technical level, an NFT is simply an entry in a blockchain database. There can be thousands of CryptoKitties, but each one has distinct metadata. When you buy a CryptoKitty, you’re acquiring the specific token linked to that cat – not a generic version.
A few examples that show how NFTs secure identity and provenance on blockchain:
- CryptoPunks – a legend: the first 10,000-punk collection. As of 07/08/2025, average price was ~38.99 ETH (per https://www.coingecko.com/ru/nft/cryptopunks).
- NBA Top Shot – a breakthrough in digital collectibles: NFT “moments” of classic NBA plays. Over $5M in the first month. Notably, it runs off Ethereum.
- Hashmasks – 16k+ unique, randomly generated mask characters created by 70 artists: beautiful and pricey.
Collectibles and Art
We’ve mentioned CryptoKitties, but the collectibles market is vast. Art is a core vertical.
Paintings and sculptures can be authenticated by experts before minting their NFTs. When a collector sells, they list the NFT at auction as proof that the piece is real and they’re the rightful owner.
This digitizes provenance and helps prevent forgery and fraud. The same applies to baseball cards, stamps, jewelry, autographed guitars – any collectible. Blockchain security guarantees transaction legitimacy.
Top Projects
- SuperRare – early curated platform for 1/1 digital works; high average quality and prices.
- Foundation – newer, curated boutique platform.
- Rarible – very open: anyone can mint; a general NFT marketplace (not just crypto-art).
- OpenSea – the largest NFT marketplace overall; strong on secondary sales, but you can mint too.
- Nifty Gateway – popular crypto-art drops, often editions + a 1/1; home to huge weekend sales (e.g., Beeple). Strict curation.
- Blur – known for innovative features and comparatively high NFT liquidity.

Online Games
NFTs are transforming gaming. Players routinely buy items like skins and weapons; turning these into NFTs powers an in-game blockchain economy. Traditional online games and even casinos are getting involved, letting players (and companies) extract real value. Ticketing for shows and sports can also be issued on-chain – each ticket is unique, i.e., an NFT – standardizing ownership but allowing different market values within a category.
Top Projects
- Axie Infinity – the largest crypto game: breed and battle Axies; buy land and build kingdoms.
- Gods Unchained – classic collectible card game.
- Neon District – cyberpunk RPG.
- Sorare – football (soccer) manager plus collectibles.
- CryptoKitties – the original kitty-breeding game.
- Mobox – a platform of play-to-earn NFT games.
Identification and Certification
Non-transferable NFTs could represent birth certificates, passports, or driver’s licenses. They wouldn’t be tradable but could interoperate with authorities for verification. You could share them with employers, doctors, or others who need your info.
University diplomas could be issued as NFTs. You might ask to see a family doctor’s verified NFT diploma. Companies’ customer data (visit history, preferences) could be tokenized and stored.
NFT Token Standards
The Ethereum ecosystem primarily uses the ERC-721 standard, which defines how to build non-fungible tokens and ensures they work seamlessly with wallets and marketplaces. Standards like this matter because they make NFTs interoperable within the ecosystem. ERC-721 underpins most collectibles and game assets.
An evolution of it – ERC-1155 – allows for “semi-fungible” tokens. In this case, a single ID can represent a whole category of items (for example, 1,000 swords of the same type in a game).
ERC-998 combines regular assets with NFTs. There aren’t many such assets yet, but the possibilities are interesting and likely to grow.
Other ecosystems have their own NFT standards: BSC, Solana, TON, Tron, Polkadot, Ravencoin, and more. Projects like DGoods aim for multi-chain compatible NFT standards; Cosmos is developing an NFT spec for the Cosmos SDK.
Minting Your Own NFT
Minting (tokenizing an object) is called minting. The easiest place to mint a sketch or quick render is Rarible or OpenSea.
- Rarible mints immediately, so you’ll pay Ethereum gas up front – whether or not it sells. Browse other artists first before risking gas.
- OpenSea supports lazy minting: you prepare the listing, but the actual on-chain mint (and gas cost) happens only when a buyer appears.
You can also mint and sell NFTs on the built-in marketplace of the Blum game’s Telegram bot (on the TON blockchain), where minting costs pennies: https://t.me/blum. Other TON NFT bots include Getgems and Disintar. Major CEXs like OKX and Bybit offer NFT marketplaces. On Solana, check Tensor and Magic Eden (multi-chain). On Ethereum: Rarible, Blur.
How to Trade and Store NFTs
Decide your niche. Gamers might start with Axie Infinity or The Sandbox. Football fans can try the free-to-play Sorare. There are many NFT games.
If you prefer art, try buying something affordable on OpenSea or Rarible, or mint your own.
Buying and holding NFTs differs from trading fungible crypto. You’ll usually need crypto (e.g., ETH) to purchase – though some sellers accept fiat. Each token is unique and listed on a marketplace connecting buyers and sellers; you’ll negotiate and transact peer-to-peer.
Use MetaMask as your primary wallet (a browser extension for quick, convenient transactions).
To buy crypto and fund MetaMask, you can use a centralized exchange like Bybit and complete quick registration/KYC.
Important: beyond the NFT price, you must pay gas. Depending on network load, that can be ~0.02–0.08 ETH. On other chains like TON or Solana, minting is much cheaper.
The Outlook for NFT Assets
NFTs can represent almost anything – personal records, academic credentials, property rights, or collectibles – giving users the ability to trade and verify ownership across borders.
Conclusion
Mass adoption isn’t far away; in fact, it’s already starting. The biggest trends for 2025 point to NFT integration in traditional industries, AI-generated digital content, and gaming.
To sum up: NFTs are more than just a trend – they’re reshaping how we define ownership in the digital world. As Artur Sychov, founder and CEO of Somnium Space, told CoinTelegraph: “The art industry today is a fast-growing sector for NFTs. Owning both a digital copy and a physical version is becoming a new kind of profitable business. The world is changing rapidly – and NFTs will be the foundation of tomorrow’s economy.”
