NFTs (Non-Fungible Tokens) were the boom of 2021, but their technology goes far beyond expensive JPEGs. Understanding what they are and how they work is fundamental to understanding the crypto ecosystem.
What is an NFT
An NFT is a unique, unrepeatable token on a blockchain. Unlike Bitcoin or ETH (which are fungible: 1 BTC = 1 BTC), each NFT is different and not interchangeable.
How They Work Technically
The ERC-721 Standard
On Ethereum, NFTs are created with the ERC-721 standard. Each token has a unique ID and a verifiable on-chain owner.
Metadata and Storage
- The NFT itself is just a blockchain record
- The image/file is stored on IPFS or Arweave (decentralized)
- The NFT "points" to the file via a URI
Real Use Cases Beyond Art
Gaming
Game items as NFTs: players truly own their items and can sell them outside the game.
Digital Identity
DIDs (Decentralized Identifiers) and verifiable credentials as NFTs: diplomas, certificates, memberships.
Tickets and Events
Tickets as NFTs eliminate forgery and enable transparent secondary markets.
Intellectual Property
Musicians and creators tokenizing royalties: fans invest in songs and receive a share of income.
RWA (Real World Assets)
Real estate titles, fractional shares of physical art and more.
Market State in 2026
After the 2022-2023 crash, the NFT market has reconsolidated. Purely speculative collections have disappeared, but NFTs with real utility (gaming, identity, RWA) continue growing.
How to Buy NFTs
- Create a wallet (Rabby Wallet recommended)
- Buy ETH or SOL on Binance or Coinbase
- Connect your wallet to marketplaces like OpenSea, Blur or Magic Eden
- For maximum security, use Ledger
Risks
- Liquidity: many NFTs are hard to sell
- Scams: rug-pull collections are common
- Rights: buying an NFT doesn't always mean owning the art rights
- Storage: if the server hosting the image disappears, you lose the content
Conclusion
NFTs are a technology with real potential beyond speculation. The key is distinguishing between projects with utility and those just seeking hype. In 2026, NFT technology is invisible infrastructure supporting gaming, identity and digital ownership.
