Unlike cryptocurrencies like Bitcoin, which are fungible and interchangeable with each other, each NFT is unique and non-replicable. NFTs can represent works of art, music, videos, collectibles, and even virtual real estate. Using blockchain technology, the ownership and authenticity of an NFT are guaranteed and traceable.
NFTs are created through processes called "minting," which record the unique data of the token on the blockchain. This allows artists and creators to monetize their work, selling it along with the rights, directly to buyers without intermediaries. But not just art, NFTs are increasingly proving to be a necessary and highly advantageous tool for anyone who holds objects or archives of digital objects that they want to protect in their integrity and traceability.
There are specific platforms where you can trade NFTs, such as marketplaces, and there are minting services to create new ones.
