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.

OurNetwork contributors and the Dune team are partnering up to bring to fruition Web3's first learn-to-earn data program. We'll spend 30 days teaching a cohort of 30 students how to analyze data in Web3 and communicate their work publicly.

This first cohort was from Oct - Nov 2021, but all material were released publicly on Mirror for anyone to follow along with. 

**Week one:** Learning to become an Etherscan detective, no using premade tables yet!

- Lecture 1: Looking at basic call and event data on Ethereum L1.
  - navigation on Dune, and how to do basic SELECT queries on data tables.
- Lecture 2: Creating basic statistics for L2 data and bridges potentially.
  - how to do aggregate, group by, and CTE queries

**Week two:** Making sense of smart contracts, specifically learning to work with composability!

- Lecture 3: Decoding smart contracts into data tables and working with data from multiple events
  - How to do basic joins and unions, and using Dune Decode
  - Using tables prices.usd to get to more informed data tracking.
- Lecture 4: Querying across DeFi and DAOs
  - More advanced joins, and windows/partitions.
  - Introduce dex.trades.

**Week three:** Putting it all together, to become an open-source query Dune Wizard!

- Lecture 5: Creating complex but reusable queries.
  - How to create User Generated Views and Materialized views
- Lecture 6: Working with NFTs
  - Working with nft.trades and NFTs more generally

**Week four:** Dashboards and Storytelling, really connect with the community behind the data!

- Lecture 7: Telling stories with your charts, formatting well
- Lecture 8: All about using parameters for really custom and flexible dashboards.

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.

Community education platform for developers in the non-fungible token space.

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.


Engaging community members to contribute to the Filecoin protocol, project and ecosystem

Filecoin Dev Grants


The Data Fund exists to support projects that further the vision of a decentralized data economy and welcomes all proposals. It is funded by a 10 million DATA allocation set aside from the initial project funds.

Quick Response grants offer up to $5000 USD and they are available for building integrations, demo apps, adding quality free data sources to the marketplace, research, community initiatives and other smaller projects.

Project grants offer up to $50,000 USD, and are available to fund Data Union applications, data tools and other large scale projects.

The Graph Grants focuses on funding **protocol infrastructure**, **tooling, dapps** and **subgraphs,** and **community building** efforts.

When applying, keep the following in mind:

- Be specific about your project's objectives, the milestones and roadmap
- Share all relevant research and thinking - even if you're in pre-development, we can help!
- Make it clear how the project is aligned with The Graph and could benefit the ecosystem
- Identify gaps in The Graph that could use improvement, do you have a solution?
- If you think your idea is needed, make sure to make the case for it

This tutorial will teach you how to query onchain data using the amazing Dune Analytics platform. Dune Analytics is the all-in-one destination to query, visualise, share and explore human readable smart contract data. It’s trusted by a lot of awesome companies like Gnosis, Compound and Bancor.

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.
