The core features of NFTs include:

Uniqueness: Each NFT has a unique identifier, making it non-fungible and indivisible. This allows it to represent specific digital assets, such as a painting, a music album, or virtual items in a game.

Immutability: NFTs are stored on the blockchain, which ensures that their ownership and transaction records cannot be altered, providing transparency and authenticity.

Proven Ownership: Purchasing or holding an NFT proves ownership of the item and allows for tracking its origin and transaction history.

Tradability: NFTs can be traded on various markets, allowing users to buy, sell, exchange, or auction these digital assets.

NFTs initially gained significant attention in the art world, with many digital artists selling their works through NFTs and earning unprecedented profits.
