✦ Key Insight

Enables verifiable digital scarcity and ownership for art, collectibles, gaming items, domain names, and even real-world assets. Traders speculate on, flip, or use NFTs as collateral in DeFi.

✕ Common Misconceptions

Buying without verifying contract authenticity; ignoring royalty or metadata permanence; overpaying in thin markets; storing valuable NFTs only in hot wallets.

Detailed Explanation

How It Works: Typically minted as ERC-721 or ERC-1155 tokens. Metadata (image, traits) is stored on-chain or via IPFS. Ownership transfers via standard token transfers; marketplaces facilitate discovery and sales.

FAQs:
Do I own the copyright? 

Usually only the token, not underlying IP, checks terms.
Can NFTs be fractionalized? 

Yes via additional protocols.
Still relevant in 2026? 

Yes for utility, gaming, identity, and selective collectibles.

In Practice

“An artist mints a digital painting as an NFT on Ethereum, allowing buyers to prove ownership and trade it on NFT marketplaces like OpenSea.”

Blockchain

A blockchain is a decentralized digital ledger that records transactions in blocks, links those blocks together, and makes the record difficult to alter.
