A Non-Fungible Token (NFT) is a unique and unrepeatable digital token that has become a collectible in the virtual world. When we talk about fungible, we mean that it can be exchanged for an equivalent, unlike non-fungible tokens, which are limited in quantity. NFTs should be thought of as any other tangible work in real life, such as books, paintings, records, etc. The problem we would encounter is the originality or seal of authenticity of these works. This is what non-fungible tokens are about: a seal of authenticity embedded in blockchains, creating blockchain. Even if the digital work is replicated, NFTs can protect the ownership and/or authorship of that art. This means that it is not exclusive content, but rather the property of the user, which is verified with a certificate of authenticity for the work. To create your NFT, you can use one of the established platforms, most of which use Ether, a cryptocurrency belonging to the Ethereum ecosystem, for their transactions. The first step is creating an NFT platform and a wallet that is compatible with Ether. You\'ll also need to have some Ether in your wallet. OpenSea is considered the leading NFT marketplace, and it doesn\'t charge for storing tokens. Go to your profile icon and select \"Create\" in the upper right corner. You can upload image files, videos, music files—virtually any digital content. Accepted formats include JPG, PNG, GIF, SVG, MP4, WEBM, MP3, WAV, OGG, GLB, and GLTF. Although the maximum file size is 100 MB, the platform recommends uploading files smaller than 40 MB to speed up the upload process. Next, you\'ll need to customize your NFT. Segment it into a collection, add ownership, levels, and content statistics. In this section, you\'ll need to define how many units of the object you want to store. Alternatively, you can choose which blockchain you want to mint your NFT on. When you\'re finished, press the create button and you\'re done. Now you can sell your NFT! ...
