In recent years, the digital world has witnessed astonishing transactions: a GIF sold for over $500,000, a single tweet fetched $2.9 million, and a purely digital artwork auctioned for 450 million RMB (about $69 million). While these figures may sound surreal, they are real—and they all revolve around one revolutionary concept: NFTs (Non-Fungible Tokens). As blockchain technology evolves, NFTs are redefining how we create, own, and trade digital assets. But what exactly are NFTs? Are they secure? And can anything become an NFT?
Let’s dive into this digital phenomenon and explore how NFTs are transforming ownership in the digital age.
What Is an NFT?
NFTs are unique digital tokens built on blockchain technology. Unlike cryptocurrencies such as Bitcoin or Ethereum—which are fungible (interchangeable like dollars)—NFTs are non-fungible, meaning each token is one-of-a-kind and cannot be replaced by another.
"An NFT is essentially a digital certificate of ownership and authenticity," explains Professor Zhou Qin from the School of Economics and Management at Southeast University. "It represents a unique digital asset—like a tweet, a piece of digital art, or even a virtual real estate plot—but it is not currency itself."
Think of it this way: traditional money operates like game tokens at an arcade. One token equals one game, and every token is identical. But an NFT is more like owning the original signed blueprint of that arcade machine—rare, verifiable, and irreplaceable.

The Technology Behind NFTs
At its core, blockchain is a decentralized ledger that securely records data across thousands of computers. On top of this foundation, platforms like Ethereum have developed what’s known as the Ethereum Virtual Machine (EVM)—a global, shared computing environment where developers can build applications.
NFTs are one such application. Using smart contracts (self-executing code), creators can "mint" an NFT by linking a unique token to a specific digital file—be it an image, video, audio clip, or text.
Each NFT contains metadata that verifies:
- Ownership
- Creation date
- Creator identity
- Transaction history
This ensures transparency and prevents duplication. As Zhou Ping, co-founder of Nanjing Pure White Matrix Technology, puts it: “Non-fungibility means non-interchangeable and non-replicable. You can exchange one Bitcoin for another with no difference—but no two NFTs are the same.”
Why Can’t NFTs Be Split?
Another defining trait of NFTs is indivisibility. While you can send 0.5 ETH, you can’t own half of an NFT. Just as selling one window of a house doesn’t transfer ownership of the entire property, splitting an NFT destroys its integrity and value.
Can Everything Become an NFT?
The short answer: yes, if it can be represented as digital data.
The journey of NFTs began in 2016 when two developers created CryptoPunks—10,000 algorithmically generated pixel-art characters stored on Ethereum. Soon after, CryptoKitties, a blockchain-based game where users breed and trade virtual cats, went viral—clogging the Ethereum network due to overwhelming demand.
Then came pivotal moments that brought NFTs into mainstream consciousness:
- Jack Dorsey’s first-ever tweet sold for $2.9 million
- The animated “Rainbow Cat” GIF fetched over $500,000
- Digital artist Beeple sold a collage for $69 million at Christie’s
These sales weren’t just about the files—they were about provenance, scarcity, and emotional value.
Zhou Ping emphasizes: “If you can describe an object’s properties and package it as data, you can mint it as an NFT.” From digital collectibles and music albums to virtual fashion and in-game items—NFTs enable true digital scarcity.
Real-World Applications Beyond Art
While digital art dominates headlines, NFTs are being used in transformative ways:
- Gaming: Players truly own in-game assets (e.g., skins, weapons) and can trade them across platforms.
- Real Estate: Tokenizing physical properties allows fractional ownership and streamlined transfers.
- Identity & Credentials: Academic degrees, licenses, or memberships can be issued as verifiable NFTs.
- Supply Chain: Luxury brands use NFTs to prove authenticity of high-end goods.

The Value Behind Seemingly Useless Items
Why would someone pay millions for a meme or a tweet?
The answer lies in perceived value—much like physical collectibles. A baseball card isn’t inherently valuable, but rarity, historical significance, and cultural relevance drive its price.
Jack Dorsey’s tweet—“just setting up my twttr”—is historically significant as the birth of Twitter. Anyone can view or copy it, but only one person holds the verified ownership via NFT.
This distinction hinges on two types of consensus:
- Technical Consensus: The data exists securely on the blockchain.
- Social Consensus: The community acknowledges the owner’s rights.
Without both, the system fails.
Are NFTs Just a Bubble?
Critics argue that NFTs resemble a “greater fool theory” market—where prices rise only because buyers believe someone else will pay more later.
According to NonFungible.com, NFT market volume reached $241 million in just one month—surpassing the total transaction value from 2018 to 2020 combined ($338 million). This explosive growth has attracted speculation—and caution.
Zhao Yilei, blockchain ecosystem lead at Pure White Matrix, warns: “NFTs can be forged if verification systems aren’t transparent.” For example, two identical images could be minted as separate NFTs—one legitimate, one fraudulent. Only platforms with open databases can reliably verify authenticity.
Moreover, owning an NFT doesn’t always mean owning copyright. You might own the token, but the creator may retain reproduction rights.
Zhou Qin cautions: “Digitizing assets increases efficiency and lowers transaction costs—but doesn’t guarantee authenticity of the underlying asset.” Bridging physical and digital trust remains a challenge.
Frequently Asked Questions (FAQ)
Q: Can I copy an NFT file?
Yes—you can download or screenshot the associated image or video. But you won’t own the verified original. It’s like printing a Picasso—it’s not the real masterpiece.
Q: Is buying NFTs safe?
Security depends on the platform and wallet used. Reputable marketplaces and cold wallets reduce risks, but scams exist. Always verify smart contracts and sellers.
Q: Do NFTs have real-world utility?
Absolutely. Beyond collectibles, they’re used in gaming, identity verification, ticketing, and decentralized finance (DeFi).
Q: Can I sell my NFT?
Yes. Once you own an NFT, you can list it on secondary markets like OpenSea or Rarible and sell it for profit—if there’s demand.
Q: What happens if the hosting platform shuts down?
Most high-quality NFTs store metadata on decentralized networks like IPFS (InterPlanetary File System), ensuring permanence even if platforms disappear.
Q: Are NFTs environmentally harmful?
Early NFTs relied on energy-intensive proof-of-work blockchains (like Ethereum pre-upgrade). Now, most use eco-friendly alternatives or Ethereum’s energy-efficient proof-of-stake model.

The Future of Digital Ownership
NFTs represent more than speculative assets—they signal a shift toward user-controlled digital economies. In China, mobile payment adoption leapfrogged Western systems; similarly, strategic use of NFTs could revolutionize supply chains, intellectual property rights, and creative industries.
As Zhao Yilei notes, today’s NFT boom may resemble a "hot potato" game—but beneath the hype lies real innovation. With proper regulation, technological refinement, and broader adoption, NFTs could become foundational tools for asset digitization across sectors.
From tweets to tickets, art to assets—the era of verifiable digital ownership is here.
