How Do NFTs (Non-Fungible Tokens) Work?
What Are NFTs & Why Are They So Popular?
NFTs (Non-Fungible Tokens) have revolutionized digital ownership, creating new opportunities for artists, creators, and investors worldwide. Whether it’s digital art, music, or even virtual real estate, NFTs have taken the internet by storm, with sales reaching billions of dollars. But how do they work, and why are they valuable? In this comprehensive guide, we’ll break down NFTs in simple terms, explain how they function, and explore their real-world applications.
What Does ‘Non-Fungible’ Mean?
Before diving into how NFTs work, let’s clarify the term "non-fungible."
- Fungible assets (like Bitcoin or money) can be exchanged one-for-one without changing their value. Example: A ₹100 note is equal to another ₹100 note.
- Non-fungible assets, on the other hand, are unique and cannot be exchanged on a one-to-one basis. Example: The Mona Lisa is one of a kind; no replica holds the same value.
👉 NFTs are digital assets that are unique and cannot be replaced with something else. These could be digital art, music, videos, tweets, or even virtual land in metaverse platforms.
🛠️ How Do NFTs Work?
NFTs are powered by blockchain technology, primarily the Ethereum blockchain. However, other blockchains like Solana, Binance Smart Chain, and Tezos also support NFTs.
Here’s a simplified step-by-step breakdown of how NFTs function:
1️⃣ Creation (Minting)
- An artist, musician, or creator uploads their digital content to an NFT marketplace (e.g., OpenSea, Rarible, or Foundation).
- The NFT is then minted (converted into a blockchain-based asset), creating a unique record.
- Smart contracts define ownership and specify details like royalty payments.
2️⃣ Ownership & Uniqueness
- Once minted, an NFT has a unique token ID stored on the blockchain.
- The ownership details, metadata (description, image, or asset data), and transaction history are all recorded and cannot be altered.
3️⃣ Buying & Selling NFTs
- NFTs can be listed for sale on marketplaces. Buyers can either purchase at a fixed price or participate in auctions.
- Transactions occur via cryptocurrency payments (e.g., ETH for Ethereum-based NFTs).
- Once purchased, ownership is transferred to the buyer, ensuring verified proof of ownership.
4️⃣ Royalties & Smart Contracts
- Some NFTs have built-in royalties, meaning the original creator earns a percentage every time the NFT is resold.
- Smart contracts ensure automatic payments and ownership tracking without intermediaries.
💡 What Gives NFTs Value?
Not all NFTs are valuable, but certain factors contribute to their worth:
✅ Scarcity & Uniqueness: Rare or one-of-a-kind NFTs have higher demand.
✅ Utility & Functionality: NFTs with in-game perks, access to exclusive content, or metaverse assets hold more value.
✅ Community & Hype: Celebrity endorsements and trending NFT collections increase demand.
✅ Ownership History: NFTs owned by famous personalities (e.g., an NFT bought by Amitabh Bachchan) can appreciate in value.
✅ Aesthetic & Emotional Value: Collectors may buy NFTs purely for artistic appreciation or sentiment.
🔥 Where Are NFTs Used? Popular Real-World Applications
🎨 1. Digital Art & Collectibles
- Artists can sell their digital paintings as NFTs, ensuring authenticity and ownership rights.
- Example: Beeple’s NFT artwork "Everydays: The First 5000 Days" sold for $69 million at Christie’s auction.
🎵 2. Music & Entertainment
- Musicians can sell exclusive tracks or albums as NFTs.
- Example: Indian music producer Ritviz released NFT-based limited edition music.
🎮 3. Gaming & Metaverse
- Gamers can buy in-game assets (weapons, skins, characters) as NFTs.
- Virtual real estate in metaverse platforms like Decentraland & Sandbox is sold as NFTs.
📜 4. Sports & Memorabilia
- NFT trading cards of sports icons (Sachin Tendulkar, Virat Kohli) are gaining popularity.
- Example: NBA Top Shot sells video highlight NFTs of basketball moments.
📜 5. Real Estate & Documentation
- Property ownership can be tokenized as NFTs to prevent fraud and simplify transactions.
- Smart contracts can automate property sales and lease agreements.
⚖️ Are NFTs Legal in India?
India is still developing its regulations for NFTs and cryptocurrencies. Currently:
✅ NFTs are not illegal but lack clear government oversight.
✅ Some Indian celebrities (e.g., Amitabh Bachchan, Salman Khan) have launched their own NFT collections.
✅ The Indian government is exploring a Digital Rupee (CBDC), which may impact the NFT ecosystem.
