NFT (Non-Fungible Token) is an invention of a blockchain-based technology that makes it be a non-interchangeable unit of data that can be traded digitally. The work of NFT is similar to cryptocurrency as it relies on blockchain to maintain the record of all transactions. Nowadays, NFT has been used for digital art trading as a form to support digital creators without worrying about piracy or theft issues. OuterSpace, a minimalist NFT marketplace, is intended as a space for digital creators and collectors to make transactions.
