Non-Fungible Tokens (NFTs) represent unique digital assets on the blockchain, enabling ownership of digital art, collectibles, and other unique items. Unlike cryptocurrencies which are fungible and interchangeable, each NFT is distinct and cannot be replicated. This comprehensive guide explores NFTs, their uses, and investment considerations.
What Are NFTs
NFTs are unique digital tokens representing ownership of digital or physical assets. Each NFT has distinct properties encoded in smart contracts. NFTs prove authenticity and ownership through blockchain immutability. They enable creators to monetize digital content directly. The NFT market reached $25+ billion in 2021.
