There are many kinds and applications of NFTs. Before we dive into the details, let's learn about a key term: **fungibility.** ### What is fungibility? If something is **fungible**, it's easily exchanged with something of equal value. Don't get overwhelmed by the idea of **fungibility;** it's just the ability of a good or an item to be interchanged with other individual goods or items of the same type. A simple comparison of fungible, semi-fungible, and non-fungible items is pictured below. Token types Fungible items like a dollar bill, gold, or even cryptocurrencies like Bitcoin and Ethereum, can be substituted with one another without losing value. They are **fungible**. ### Non-fungibility and NFTs If something is **non-fungible**, it means it cannot be replaced. It represents something unique in value - and that's what an NFT is! The **token** part of a **Non-Fungible Token** refers to a digital certificate stored on a publicly verifiable distributed database, also known as a blockchain. The information on this digital certificate, also known as a smart contract, makes each NFT unique. No two NFTs can be swapped, and this makes them **non-fungible**. Examples of NFTs include digital art, collectibles, virtual reality items, crypto domain names, ownership records for physical items, and more! ### Different types of NFTs There are two types of NFTs currently supported on Shareverse. * **1/1 NFTs** - known as **ERC-721** tokens on Ethereum and Polygon. * **Semi-fungible NFTs** - known as **ERC-1155** tokens on Ethereum and Polygon. **1/1 NFTs**, known by their token standard as **ERC-721** on Ethereum, are the classic definition of Non-Fungible Tokens that we've described above. Each NFT is unique and distinct from other NFTs. **Semi-fungible NFTs**, known by their token standard **ERC-1155** on Ethereum, are slightly different. Because they are semi-fungible, the items themselves are distinct from other NFTs. However, they might have a quantity greater than one. These NFTs are great for gaming items and creating membership passes for your community!
