Labs:
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 5 – Modifiers
-
In this Lab we will work with modifiers
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
