NFT
An NFT (non-fungible token) is a unique cryptographic token on a blockchain that represents ownership of a specific digital or physical asset and cannot be exchanged on a one-to-one basis like fungible cryptocurrencies.
✦ 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.
