NFTs are created using blockchain technology, which allows for secure and transparent tracking of ownership and transaction history. They are typically stored on decentralized marketplaces or platforms, where buyers can purchase and trade them using cryptocurrency.

NFTs can represent a wide range of digital assets, such as artwork, music, videos, virtual real estate, collectibles, and more. They have become increasingly popular among artists and creators as a way to monetize and sell their digital creations directly to their audience, bypassing traditional intermediaries such as galleries or record labels.

The value of NFTs is determined by market demand and scarcity, with some NFTs selling for millions of dollars. However, there is also controversy surrounding NFTs, particularly around their environmental impact due to the energy-intensive process of creating and trading them, as well as concerns about their long-term value and potential for fraud.
