Brief Introduction

Use Ethereum, Solidity, and Smart Contracts to build Certificate Registration DApp based on the blockchain

Description

What we cover

  • We briefly cover the philosophy of the blockchain and Ethereum.

  • Then we will explain how blockchains work, what is Decentralized App and how smart contract communicates with DApp

  • We setup the easy development environment, including tools that can be used with minimum steps

  • And the biggest part of the course is dedicated to guiding you through a simple Decentralized App


Some of the keyword definition:

Blockchain is a growing list of digital pieces of information which are linked using cryptography. It is an open, distributed ledger that can record transactions between two parties efficiently and also in a verifiable and permanent way.

Decentralized applications (dApps) are applications that run on blockchain rather than a database.

Smart contract is defined as pieces of computer code that self-execute when predetermined conditions are fulfilled. The results of the transaction will be written onto a distributed ledger or blockchain.


We covered the following concept:

  • Ethereum

  • Account

  • Gas

  • Smart Contract

  • Decentralized App

  • Blockchain

  • Bitcoin

  • Solidity

  • Web3.js

  • Ropsten Testnet

What tools and libraries are used?

  • Ethereum

  • The Metamask Chrome extension

  • The Solidity smart contract language (0.5.0)

  • The Web3.js(Web3 1.0.0)

  • The Ganache Ethereum node emulator

  • Github

  • Visual Studio Code (text editor)

  • The Ropsten test network

All our codes are stored in Github and the solidity code will be stored as .sol file.

  • Lesson 2 unit 1: @hashcademy-> choose certificate_dapp -> choose branch master

  • Lesson 2 unit 2: @hashcademy-> choose certificate_dapp -> before modify javascript:  choose branch 1a, after modify javascript: choose branch 2

  • Lesson 2 unit 3: @hashcademy-> choose certificate_dapp -> choose branch 3

  • Lesson 2 unit 4: @hashcademy-> choose certificate_dapp -> choose branch 4
