# NFT Introduction **👋** Hello! NFTs can be exciting, NFTs are a way for artists and others to sell their digital art, and ensure authenticity. NFTs are sold on websites like [opensea.io](https://opensea.io/) or their on creator websites. NFTs are short for Non Fungible Token, these tokens live on the Ethereum blockchain and prove authenticity. You may be wondering, well cant i just download the NFT as an image and it's the same? Well yes you can download it, but it will never be the original if that makes sense. We all know of the monalisa paintings, or 1 of 1 shoes.. but if fakes are made they arent the real deal. {% hint style="success" %} You can read through this guide for information on how to purchase, sell and get started with NFTs. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
