What are NFTs?
A non-fungible token is a unique and non-interchangeable unit of data stored on a blockchain, a form of digital ledger. NFTs can be associated with reproducible digital files such as photos, videos, and audio.
OpenSea is an NFT marketplace built on Ethereum that allows users to create, trade, and exchange NFT assets directly on the platform. Basically, NFTs can be art, virtual experience, music, or virtual property that are unique things on the blockchain.
