Finally, the time has come for me to write about Web3 Development and how to actually start doing it.
Are you tired of building boring old web applications that are centralized and controlled by a single entity? Are you ready to enter the exciting world of decentralized applications and unleash the full potential of the blockchain? If so, then web3 is for you!
⚡️ What it is?
We already discussed web3 in our previous newsletters but if you've missed it, check it out:
Web3 is the cutting-edge technology that allows developers to build dApps on the blockchain, enabling them to create applications that are decentralized, secure, and transparent.
In this beginner's guide series to web3 development, we'll take a look at what web3 is, how it works, and what you need to know to start building your own dApps. From choosing the right blockchain platform to mastering the tools and techniques of web3 development, we'll cover everything you need to know to get started on your journey to becoming a web3 developer.
So if you're ready to join the ranks of the blockchain elite, grab your laptop and let's get started on your path to becoming a web3 developer!
🔍 Small steps
Familiarize yourself with the basics of blockchain technology and how it works. This will provide you with a foundation for understanding web3 and the role it plays in the blockchain ecosystem. We got you covered with this!
Learn about web3 and what it is. (also with this)
Choose a blockchain platform to develop on. There are several popular blockchain platforms that support web3 development, such as Ethereum, EOS, Polkadot and TRON. Each platform has its own unique features and capabilities, so choose one that aligns with your goals and objectives.
Learn a programming language that is supported by the blockchain platform you have chosen. Most blockchain platforms support popular programming languages such as JavaScript, Python, and Solidity.
Explore the web3 libraries and tools available for the blockchain platform you have chosen. These will enable you to easily interact with the blockchain and build dApps.
Start experimenting and building simple dApps to get a feel for web3 development. This will help you understand the basics and give you a foundation to build more complex applications in the future.
🔨 Smart Contract Development with Solidity
Before starting you will need to know how to create smart contracts.
The most popular programming language for developing smart contracts and dApps is Solidity.
Solidity is a high-level, contract-oriented programming language used for implementing smart contracts on the Ethereum blockchain.
So, what do you need to start?
The basics of Solidity, including its syntax and data types.
The concept of smart contracts and how they are used on the blockchain.
The principles of object-oriented programming and how they apply to Solidity.
The Ethereum Virtual Machine (EVM) and how it executes Solidity code.
The tools and libraries that are available for developing and testing Solidity contracts, such as Remix and Truffle.
🔨 Where to start with Solidity
If you're new to Solidity, there are a number of resources you can use to learn the language and get started building smart contracts. Here are a few suggestions:
The Solidity documentation: This is the official documentation for Solidity, and it covers all the basics of the language, as well as more advanced topics. You can find it here: https://solidity.readthedocs.io
The Solidity tutorial on the Ethereum website provides a step-by-step guide to writing your first smart contract in Solidity. You can find it here: https://ethereum.org/en/developers/tutorials/waffle-say-hello-world-with-hardhat-and-ethers/
Freecodecamp - Really nice one - https://www.freecodecamp.org/news/learn-solidity-handbook/
The Solidity course on Udemy: This course is a comprehensive introduction to Solidity. It covers everything from the basics of the language to more advanced concepts like contract testing and deployment. You can find it here: https://www.udemy.com/course/ethereum-and-solidity-the-complete-developers-guide/
The Solidity section on the Ethereum Stack Exchange: This is a community-driven Q&A site where you can ask questions and get help with Solidity. You can find it here: https://ethereum.stackexchange.com/questions/tagged/solidity
🔨 What do you need?
A text editor: You will need a text editor to write your Solidity code. There are many text editors available, such as Sublime Text, Visual Studio Code, and more. Choose a text editor that you are comfortable with and that has syntax highlighting for Solidity.
A Solidity compiler: Solidity code needs to be compiled before it can be deployed to a blockchain. You will need a Solidity compiler to compile your code. There are many Solidity compilers available, such as Remix, Truffle, and Solc.
A blockchain network: You will need a blockchain network to deploy your Smart Contracts to.
A wallet: You will need a wallet to manage your blockchain accounts and interact with your Smart Contracts. There are many wallets available, such as MetaMask, MyEtherWallet, and more. Choose a wallet that is compatible with your chosen blockchain network (of course).
A debugger: It is a good idea to use a debugger to help you find and fix errors in your Solidity code. There are many debuggers available, such as Remix Debugger, Truffle Debugger, and more.
