The InterPlanetary File System (IPFS) is a peer-to-peer network protocol for storing and sharing data in a distributed file system, with addresses based on content, not location. In this course, we'll dive into the basics of cryptographic hashing and content addressing on the decentralized web, take a look at how Content Identifiers (CIDs) are constructed in IPFS, and get hands on with the js-ipfs API. Through JavaScript coding challenges, we'll learn to store and share files with peers, create links between Merkle DAGs, and explore the Mutable File System (MFS), which lets you work with content-addressed files and directories as if you were using a traditional named-based file system. As we go, we'll learn more about other protocol layers of the Web3 stack that work in parallel with IPFS, including Multiformats, IPLD, libp2p, and Filecoin.

ProtoSchool's self-guided interactive tutorials are designed to introduce you to decentralized web concepts, protocols, and tools. This course on IPFS includes both JavaScript code challenges and code-free tutorials with text-based lessons and multiple-choice quizzes. Our handy little icons will guide you to the content that fits your needs. We recommend proceeding through the tutorials in the order in which they're presented.

What does it mean to own a piece of the internet? Can you sell a meme to the highest bidder? Is the metaverse finally happening? Let's find out together!

Welcome to NFT School, a collective of web developers and technology enthusiasts here to figure out what's going on with non-fungible tokens, or NFTs. In the past few years, NFTs have gone from a niche concern within the blockchain world to a cultural phenomenon that has captured the imagination of artists, technologists, and the mass media.

As builders, we'll be exploring NFTs from the technical side, taking them apart, and seeing how they work. We'll also take a look at some of the use cases for NFTs, so that we can help build new experiences around them.

We'll be building on a background of modern web development, with a focus on JavaScript. Along the way, we'll get familiar with the core technologies that make NFTs possible, like smart contracts and content-addressed storage. If you're a newcomer to the space and find yourself confused, we want to know about it! Please open an issue (opens new window)with any suggestions for how to make this content more accessible.

To date, the Filecoin project has focused primarily on research, specification and implementation of a decentralized storage network protocol. Throughout this process we have been fortunate to work with incredible community members and contributors. Some are already building tools on the budding network in active development.

NFTs, as unique items on the blockchain, has a URI that points to data containing the metadata & the corresponding visuals. This URI can be an HTTP link, pointing to a video or image hosted on a normal server, or other services like IPFS (hash-based addresses), or Arweave (incentivized hosting of hash-based content).

There is another way, however, a format that's become increasingly popular: the usage of a data URI. These URIs contain all the information within it. There is thus no server at the other end. Using data URIs has allowed NFT creators to experiment with putting all the content related to an NFT 'on-chain'. It adds a vector of permanence to the art. If Ethereum continues, it does not need ancillary infrastructure to support it. A common format, currently, is to store the NFT visuals as SVG in the data URI, since most browsers are able to natively parse it.

It's fun, and due to some of the constraints of smart contract coding (limited execution & expensive storage), it becomes in itself a game of gas golf, trying to pack as much as one can into the architecture to create dynamic art that will live (currently) forever on Ethereum.

Store NFT visuals as SVG in the data URI, so it does not need ancillary infrastructure to support it.

If you have ever tried to understand and read about EVM before, you might have come across different ways in which EVM is defined. For instance:

- EVM is a Virtual Machine …
- EVM is a State Machine …
- EVM is a Quasi-Turing complete machine…

The Ethereum Virtual Machine can simply be understood as an isolated environment specifically designed to process smart contract transactions as well as, most importantly, determine the overall state of the Ethereum blockchain with every new block that gets mined.

EVM Part I: The ABCs of Ethereum Virtual Machine


In this video, I will guide you through the basics of the EVM, including its architecture, execution model, and bytecode. You'll learn how to write and deploy smart contracts using Solidity, and underlying working of EVM. This crash course is designed to be accessible to beginners, but also covers advanced topics. Whether you're a software engineer, blockchain enthusiast, or just curious about the inner workings of Ethereum, this video has something for you.
