Overview

---

This 3 day instructor-led course is designed for programmers and developers who want to take a comprehensive deep dive in writing smart contracts and building applications that interact with them. This course provides detailed overviews of Ethereum, smart contracts, and the development language, Solidity. The student will be exposed to Ethereum’s adaptable feature set which allows the developer to design decentralized applications for countless applications. Students will also participate in hands-on programming lab sessions to learn, develop, and advance their skills in Ethereum development. The Ethereum Development Training Course is designed for those seeking an in-depth understanding and development experience of the Ethereum Blockchain platform. Students will participate in approximately 50% programming lab time providing practical experience, enhancing their knowledge and existing skill set. Due to the technical programming lab content covered in this course, it is not recommended for those without programming knowledge and experience. The Certified Blockchain Developer Ethereum exam is included with class. Those who attend the Ethereum Development course and pass the exam certification will have a demonstrated knowledge of: An excellent overall understanding of the Ethereum architecture and Solidity language. All functional components (including smart contracts) required to develop an Ethereum Blockchain. The understanding of how to instantiate an Ethereum application on the network. An in-depth understanding of how transactions are created and implemented on an Ethereum network.

Lab Overview

Lab 0 – Understanding Components

In this Lab we discuss the components used, where to get them and how to install them.

Lab 1 – Variables

In this Lab you will get to know Remix and run simple Smart Contracts

Lab 2 – Ropsten and MetaMask

In Lab you will get Ether from the Ropsten or Rinkeby Testnet and trace the Ethers on their way to the browser-plugin MetaMask.

Lab 3 – Web3.JS Operations

During this Lab you will understand what Web3.JS is and how it is used to retrieve Information.

Lab 4 – Events

Here you will learn a classic use-case for events to overcome concurrent workflow issues

Lab 5 – Modifiers

In this Lab we will work with modifiers

Lab 6 – Mappings and Structs

Mappings and Structs are powerful data-structures which you will learn in this Lab

Lab 7 – Inheritance

When using Solidity it’s good to keep things clear and small to be able to audit it. In this Lab we discuss Inheritance

Lab 8 – Gas-Costs and Deployment

In this Lab you will learn how to optimize the smart contract, deploy the contract and what to pay attention to in practice.

Lab 9 – Final DApp, Tie it Together

We put all the components together and work with the final distributed Application.

Lab 10 – Mining

During this lab you will see the difference of mining in a proof of authority consensus network and a proof or work network.

Lab 11 – Truffle Setup

This Lab will teach how Truffle can be used to work in teams and with code locally. We will install and adapt the truffle default workflow.

Lab 12 – Truffle Unit Tests

In this Lab we will do one of the most important steps during Contract Development: Create Unit-Tests for our Smart Contract

Lab 13 – IPFS

During this Lab you will create a fully decentralized file-storage which will store files on IPFS and pointers on Ethereum

Bonus Lab – Solidity Compilation

In this Lab you will learn how to manually compile a solidity file with the command line solidity compiler
