Explore what a decentralized application and blockchain are, set up a local development environment, and build a local blockchain with the hardhead framework to understand transactions.
Explore how blockchain stores data across distributed nodes in immutable, timestamped blocks. Learn how decentralized apps run on these blockchains, ensuring privacy and censorship resistance with scalability trade-offs.
clarify the difference between decentralized applications and smart contracts, and show how Dapps use self-executing contracts to automate blockchain workflows, with IPFS front ends and Ethereum deployment.
Understand the course plan for building a decentralized app, covering local blockchain setup with hard hat, verifiers and gas fees, and using MetaMask wallets for transactions.
Install Node.js and Visual Studio Code, and configure a MetaMask wallet using Homebrew on Mac to prepare your local environment for developing decentralized apps.
Set up a local Ethereum development environment with node, npm, and Visual Studio Code, create a React app, install Hardhat, and connect MetaMask to a local blockchain.
Compile the greeter solidity contract with hardhat, generate artifacts, and deploy the project from a React app, then illustrate a sample ether transfer via metamask.
Deploy a smart contract locally using hardhat, run the sample script to deploy the greeter contract, and capture the deployed address to interact with your dapp.
Deploy a simple counter smart contract on a local Ethereum test network using remix. Compile, deploy, and interact by incrementing the counter and calling getCount.
The term DApp comes from “decentralized application” and these are applications that run on the blockchain.
Being decentralized, they do not obey the control of any single authority. They can better safeguard user privacy and resist censorship.
This type of application is taking the world by storm along with Web3, NFTs and the decentralized authority available nowadays on the Blockchain. Everyone is talking about them and developers good with these technologies will be very well paid!
With that being said, getting started with DApps is not easy, given the vast amount of options available out there.
That's why I created this simple course on DApps to help you get started on your path of developing in this field.
You will first learn how to set up a development environment on your local machine and install on it all the programming languages, IDEs and frameworks that are necessary to start writing code.
Then, we will create a local Blockchain in order to better understand its presented definition and the transactions it provides.
We will also write our very own Smart contract and deploy it both on our local Blockchain and on a testnet one, on cloud.
All these operations will not require any money, so do not worry about that, you are here to learn!
After finishing this course, you will have a clear idea on what DApps are, how a blockchain and a smart contract work and also how to set up a local environment on your machine that will get you set up to start developing them on your own.
So if all of this sounds interesting, I look forward to seeing you in the first lecture!
