Building Ethereum Dapps teaches Dapps development on the Ethereum blockchain platform. You'll begin with a mental model of how Dapps operate, and then dive into designing and implementing smart contracts in Ethereum's Solidity language. You'll explore Ethereum smart contract development tools, like Truffle and Web3, and pick up best practices for design and security. Practical exercises throughout give you valuable hands-on experience. 

In this book, you'll learn the principles of Dapps development by rolling up your sleeves and actually building a few!

Building ethereum dapps decentralized applications on the ethereum blockchain


As IBM´s official liaison to the Ethereum core developers I gave talks on blockchain topics pretty much around the world. After one keynote I was asked for a non-technical guide to understand blockchains. This is it.

The book aims to help you get your head around blockchains in general and around Ethereum specifically. Since Ethereum is currently the pre-imminent blockchain, it makes sense as reference point. The essential stuff is the same for any blockchain.

This text was written for people with a fast grasp, who are not programmers. Reading this should give you the basics to cut through the hype and to identify blockchain opportunities in your professional domain. There are tiny bits of code, which can be admired and skipped.

We´ll look at Ethereum´s benefits first, how it is used and what can be done with it; then explain blockchain machinery, visiting the terms that you´ll be confronted with in every discussion about its application. Exactly what you need to tell the signal from the noise in the echo chamber of honest misunderstandings and desperate marketing.

We take a good hard look at limitations, throw in some history and names and give a realistic outlook.

The index reads like an FAQ and you can use the book like that. However, there is a strong build up, one chapter leading to the next, as optimized path to understanding all the interconnected, moving parts. There´s quite a number of them.

Blockchains are not a trivial topic. The fact that blockchain client programs are small has fooled many people into believing it can´t possibly be that hard. The challenges are in the implications though.

But what’s in this book will put you ahead of almost everyone outside the core bubble.

A deep dive into this field now – at least getting started – will help you to become part of the fun ahead. It should allow you to stand out, land deals or a great job.

It will also make you see first hand how early we are in the game.

Hopefully, we will find a contributor to the blockchain community in you, strengthening the portfolio of real-world use cases. Ideally, you´ll learn to navigate your own uncharted course through your domain and revolutionize it.

The book aims to help you get your head around blockchains in general and around Ethereum specifically as it's the preeminent blockchain.

Ethereum: Blockchains, Digital Assets, Smart Contracts, Decentralized Autonomous Organizations


Technology is constantly evolving, and blockchain is taking development to new places, as mobile did a decade ago – and Ethereum is the leading platform for creating this new wave of applications. This book reveals everything you need to create a robust decentralized application (more commonly known as DApp). Unlike other books on the topic, this one focuses on the web application layer, and guides you in creating great experiences on top of the Ethereum blockchain. You’ll review the challenges and differences involved in developing DApps as opposed to traditional web applications. 

After a brief introduction to blockchain history and Ethereum in particular, you’ll jump directly into building a sample decentralized application, to familiarize yourself with all the moving pieces. This book offers specific chapters on querying and rendering data from the blockchain, reacting to events, interacting with user accounts, sending transactions, managing gas, handling confirmations and reorganizations, and more. You will also find a chapter dedicated to Solidity that will give you the necessary means to understand and even build your own smart contracts. 
Other important topics covered include building backend servers that act as indexing layers, and managing storage efficiently with solutions like the interplanetary file system, or IPFS. Last but not least, you will find chapters that examine the biggest problems on Ethereum today: onboarding and scalability. These include the state of the art of the available strategies to tackle them, such as meta-transactions, smart accounts, ENS, state channels, sidechains, and more.

In October 2016, the Berkeley Bitcoin Association, a group of about a dozen members, founded Blockchain at Berkeley, an organization dedicated to becoming the blockchain hub of the East Bay. They also debuted the world’s first undergraduate university-accredited blockchain course, Blockchain Fundamentals, taught to about 50 students. Alongside Blockchain at Berkeley’s education team grew a consultancy that aimed to bridge the gap between geeky bitcoin enthusiasts and technovative early-adopters in the industry to develop Proof-of-Concepts for disruptive blockchain use cases. Since then, as a result of other ambitious B@B members, R&D and Design departments have also emerged.

NFTs, non-fungible tokens, have taken the online world by storm ushering in the proclamation of a new world-wide web... web3.

For most, NFTs mean profile pictures (pfps). 🐵

This isn't the most practical use case, even if it is a lot of fun

Even if you wanted to create useful NFTs, it’s not easy to get started.

Since the tooling is still being developed, it can be confusing as to where to get started. It also doesn't help that there's a paradigm shift with app development from web2 to web3.

Here be dragons 🐉

This course is here to get you through that initial learning curve and frustrating lack of answered questions and good documentation.

Through building this project you will learn the general development lifecycle of NFT smart contracts and dApps giving you the skills to start your own projects.

By the end of this course, you will be able to do the following

- Use the OpenZeppelin Solidity library to create NFT smart-contracts
- Deploy smart contracts to Ethereum testnets
- Host static assets on IFPS
- Create a React dApp that interacts with your smart-contract API
- Confirm a wallet owns an NFT

This course will help you build a ticketing and proof-of-attendance service complete with wallet QR code scanning, using Solidity and React

Smart Contracts? They're here.  The Ethereum Blockchain?  Covered.  Solidity?  Yep!

There can be no understating it: Ethereum and Blockchain technology is the most disruptive force in years.  Companies cannot hire developers who understand blockchain technologies fast enough, but there are a tiny number of resources published to help you truly understand what blockchains are used for, let alone build apps with them.  That's the purpose of this course: to be the best resource online for learning about Ethereum, blockchains, and how to build apps with this new technology.

The development community is still figuring out the best way to use Ethereum in the creation of new and exciting apps.  I spent a tremendous amount of time to research and create best practice for interfacing with Ethereum from Javascript.  I can't overstate it enough; this course will show you the best and most easily repeatable patterns for creating production-ready apps with Ethereum.

Learn Blockchain, Solidity, and Full Stack Web3 Development with JavaScript – 32-Hour Course


You may have heard a lot of jargon related to Web3: distributed ledgers, crypto, NFTs. But what’s revolutionary about the technology is more than the sum of the technical parts; it’s the power it gives you. 

Our lives are increasingly digital and interconnected. Our screens are our windows, our data defines our identity, and more and more of our time is spent online.

Historically, trust in society comes from subjective sources — from personal connections, platforms, institutions. At its core, Web3 is a new foundation for trust, where everything can be verified and you don’t need to place your trust in a single source or entity. 

This new common trust changes what the web is, and what you can do with it. It’s a web for you to own, for us to own. Where the printing press democratized the dissemination of information, Web3 democratizes the creation and dissemination of value. 

Through a series of interactive lessons, MetaMask Learn will show you what Web3 is, why it’s important to you, and how to use MetaMask along the way.

We want to share our enthusiasm for the Web3 of today, and empower you to build, explore, and participate in the world of tomorrow.
