# TL;DR 👀

<mark style="color:purple;">**What are NFTs?**</mark>

<mark style="color:purple;">Non-fungible tokens (NFTs) are cryptographic assets on a blockchain with unique identification codes and metadata that distinguish them from each other</mark>

<mark style="color:purple;">Popular NFT standards include ERC-721 and ERC-1155</mark>

<mark style="color:purple;">NFTs are designed to give you something that can’t be copied: ownership of the work (though the artist can still retain the copyright and reproduction rights, just like with physical artwork)</mark>

<mark style="color:purple;">**NFT Marketplace**</mark>&#x20;

<mark style="color:purple;">In order to browse, buy, sell or create your own NFT, you have to visit an NFT marketplace, and the biggest one around is OpenSea</mark>
