What Is an NFT?

An NFT (Non-Fungible Token) is a type of cryptocurrency token that represents unique digital assets.

Unlike regular cryptocurrencies such as Bitcoin or Ethereum, NFTs are not interchangeable because each token has distinct properties or metadata.

Why NFTs Exist

NFTs exist to:

Represent digital ownership and scarcity
Authenticate unique digital items (art, music, collectibles)
Enable creators to monetize digital works
Facilitate decentralized marketplaces and gaming

They provide verifiable proof of ownership on the blockchain.

Transfers are transparent, immutable, and verifiable
