Blockchain for beginners:build certificate registration DApp Download

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

What you’ll learn
  • Understand the basic concept of Blockchain and Ethereum
  • Setup a private blockchain network for local development
  • Understand how smart contract works and communicates with DApp
  • Develop with the latest version of Ethereum development tools (Web3js v1.0 and Solidity v0.5.0)
  • Develop a certification registration Dapp deployed to Ethereum testnet
  • Understand how MetaMask communicates with your DApp
Requirements
  • Basic Knowledge of Javascript and Yarn
  • A Mac, PC, or Linux Machine (We use Mac in this course)
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.
