What Are NFTs?
Non-fungible tokens (NFTs) are unique digital assets built on blockchain technology. Unlike cryptocurrencies such as Bitcoin or physical money, NFTs cannot be exchanged at parity due to their non-fungible nature. Each NFT carries a distinct digital signature, ensuring authenticity and ownership. Examples include:
- Digital art (illustrations, videos, music)
- Collectibles (trading cards, sports memorabilia)
- Virtual real estate and in-game items
How NFTs Work
NFTs operate on decentralized ledgers (e.g., Ethereum blockchain), where:
- Unique identification codes verify ownership and provenance.
- Smart contracts automate transactions and royalty payments.
- Tokenization enables fractional ownership of high-value assets like art or real estate.
