Web3 is a collection of libraries that allow developers to interact with a decentralized application (DApp) on the Ethereum blockchain. It enables developers to write and deploy smart contracts, create wallets, and send transactions to the Ethereum network. Web3 provides an API for interacting with the Ethereum blockchain, allowing developers to access data stored on the blockchain and build applications on top of it. Web3 also provides tools for developers to create their own decentralized applications (DApps).

Web3 Workshop - Building Your First Dapp
Featured WorkshopFree
In this workshop, you'll learn how to build your first full stack dapp on the Ethereum blockchain, reading and writing data to the network, and connecting a front end application to the contract you've deployed. By the end of the workshop, you'll understand how to set up a full stack development environment, run a local node, and interact with any smart contract using React, HardHat, and Ethers.js.

How to Convert Crypto Currencies With GRPC Microservices in Node.js
Workshop
The workshop overviews key architecture principles, design patterns, and technologies used to build microservices in the Node.js stack. It covers the theory of the GRPC framework and protocol buffers mechanism, as well as techniques and specifics of building isolated services using the monorepo approach with lerna and yarn workspaces, TypeScript. The workshop includes a live practical assignment to create a currency converter application that follows microservices paradigms. It fits the best developers who want to learn and practice GRPC microservices pattern with the Node.js platform.
Prerequistes:- Good understanding of JavaScript or TypeScript- Experience with Node.js and writing Backend applications- Preinstall Node.js, npm- Preinstall Protocol Buffer Compiler- We prefer to use VSCode for a better experience with JavaScript and TypeScript (other IDEs are also ok)

Build Web3 apps with Javascript
WorkshopFree
The workshop is designed to help Web2 developers start building for Web3 using the Hyperverse. The Hyperverse is an open marketplace of community-built, audited, easy to discover smart modules. Our goal - to make it easy for JavaScript developers to build Web3 apps without writing a single line of smart contract code. Think “npm for smart contracts.”Learn more about the Hyperverse here.We will go over all the blockchain/crypto basics you need to know to start building on the Hyperverse, so you do not need to have any previous knowledge about the Web3 space. You just need to have JavaScript experience.

How to Build UI's for Smart Contracts
Workshop
There are many journeys we can take into becoming a web3 developer. Not all journeys require learning a completely new language and becoming a smart contract developer. In this workshop we will learn how to build our own React UI on top of any existing smart contracts on the Polygon Proof of Stake Blockchain. We will explore a basic overview of blockchains and learn about the advantages of building on Polygon. We will also gain an understanding of what Smart Contracts are, learn how to find existing ones, and learn tools that help us interact with them from a React application.
