NFT (Non-Fungible Token)
What is an NFT (Non-Fungible Token)?
NFT (Non-Fungible Token) is a type of unique digital asset stored on a blockchain, representing ownership of a specific item, artwork, collectible, or right. Unlike cryptocurrencies such as Bitcoin or Ethereum, which are fungible and interchangeable, each NFT is distinct and cannot be replaced by another identical token.
NFTs use blockchain technology to verify authenticity, ownership, and provenance of digital and physical assets.
How do NFTs work?
Stored on blockchain – NFTs are recorded on public blockchains like Ethereum, Polygon, or Solana.
Unique identifier – Each NFT has a unique ID and metadata distinguishing it from others.
Smart contracts – NFTs are governed by smart contracts (e.g., ERC-721, ERC-1155) that define ownership, transfer, and royalties.
Digital ownership – Owning an NFT means holding a verifiable proof of ownership for a specific digital asset (image, music, video, etc.).
What can NFTs represent?
Digital art – Artwork, illustrations, generative art (e.g., CryptoPunks, Beeple).
Collectibles – Rare items, trading cards (e.g., NBA Top Shot).
Music and videos – Exclusive content, albums, concert tickets.
Gaming assets – In-game items, skins, avatars (e.g., Axie Infinity).
Virtual real estate – Land in metaverses (e.g., Decentraland, Sandbox).
Membership and identity – Access passes, DAO membership tokens.
Why are NFTs important in crypto?
Create digital ownership – First time digital assets can have verified owners.
Enable creator economy – Artists and creators can sell work directly to audiences.
Programmable royalties – Automatic royalty payments to creators on secondary sales.
Digital scarcity – Proven limited supply through smart contracts.
New forms of interaction – Communities, games, and events tied to NFT ownership.
