🏆 02m: Learning Objectives

  1. Analyze the full-stack ecosystem that enables the development of smart contracts and distributed applications in Node.
  2. Identify and leverage existing boilerplate applications to establish a strong initial foundation in projects.
  3. Begin proposing, designing, and planning your own token based coin using the Truffle framework!

🤔 03m: Why You Should Know This

Frameworks boost programmer productivity by initializing a standards-based foundation with which to develop a product.

Truffle Suite provides the scaffolding to our projects, similar to Create React App or Django.

☀️ 20m: Warm Up

Answer the warm up questions below in breakout rooms:

You may answer the questions solo or in a pair.

  1. Challenge 1: What is the difference between Ether and Ethereum?
  2. Challenge 2: What is an unsigned integer?
  3. Challenge 3: What is Natspec? How is it used? Write out an example using an unsigned integer!

📖 30m: Overview


🔗 Quickstart

A world class development environment, testing framework, and asset pipeline for blockchains using the Ethereum Virtual Machine (EVM), aiming to make life as a developer easier.

Truffle Features

  • Built-in smart contract compilation, linking, deployment and binary management.
  • Automated contract testing for rapid development.
  • Scriptable, extensible deployment and migrations framework.
  • Network management: deploy to any number of public and private networks.
  • Package management via ethpm and npm, using the ERC190 standard.
  • Interactive console for direct contract communication.
  • Configurable build pipeline with support for tight integration.
  • External script runner that executes scripts within a Truffle environment.


🔗 Quickstart

Ganache Features

Ganache is a personal blockchain for Ethereum development you can use to deploy contracts, develop your applications, and run tests.

It is available as both a desktop application as well as a command-line tool (formerly known as the TestRPC).


🔗 Quickstart

Drizzle is a collection of front-end libraries that make writing dapp front-ends easier and more predictable.

Takes care of synchronizing contract data, transaction data, and more. Things stay fast because you declare what to keep in sync.


🔗 Quickstart

OpenZeppelin is a library for secure smart contract development. It provides implementations of standards like ERC20 and ERC721 which you can deploy as-is or extend to suit your needs, as well as Solidity components to build custom contracts and more complex decentralized systems.

OpenZeppelin Features

  • Focused on Security: Using industry standard contract security patterns and best practices, develop applications with reduced risk of vulnerabilities using standard, tested, community-reviewed code.
  • Compatibility: Runs on any EVM-compatible blockchain.
  • Modular Approach: Simple code, only basics. Easy collaboration and auditing.
  • Open Source: Community driven. Used by multiple organizations and individuals.
