Complete Web3.0 and Solidity Development Roadmap 2022 cover

Complete Web3.0 and Solidity Development Roadmap 2022- Table of Contents

Learning Web3.0 and blockchain development today is like buying a Bitcoin at $10 yesterday.

Entering the Blockchain industry where the average programmer is paid around $140k/year, is probably the best investment you can make as a developer.

Unfortunately, the web has a scarcity of good resources and finding a good blockchain development roadmap might rapidly become tedious.

I’ve taken the time to gather the best online videos, courses, and websites and put together the best web3.0 and Solidity development roadmap.

From complete zero programming knowledge to Solidity and Blockchain expert, that’s why we’ll start with the fundamentals of Computer Science.


1. Before Web3.0 and Blockchain: Fundamentals of Computer Science

A Skyscraper needs solid foundations to not collapse.

Blockchain development it’s a tough subject, I won’t lie. Before digging deeper into nodes and blocks and starting your roadmap, better learn the fundamentals of computer science:

The famous CS50 — fundamentals for Computer Science — free course issued by Harvard itself will teach you all you need to know to understand the basics of computers and data handling.

Once you’ll have some CS understanding, it’s time to learn how the Blockchain works, why it’s useful, and its limitations.


2. Learn The Fundamentals Of Blockchain

Blockchain wrote on a white background.

As a Web3.0 developer, you need to understand what the Blockchain is, how it works and why it might disrupt the way we exchange goods and make payments.
Blockchain technology is no more related only to crypto coins but it has become a truly distributed cloud computing system capable of running full Backends to power cutting edge Decentralized Applications (DApps).

Learn the fundamentals of the Blockchain on Coursera for Free with Blockchain 101.


3. What is a Decentralized Application?

When you’ll have learned about the blockchain, nodes, consensus, and all the main components of this technology, you’ll start to wonder:

“What kind of applications can I develop using the blockchain?”

The applications built on top of Blockchain are called Decentralized applications, or DApps, and have:

  • A standard Front-end built using JavaScript or frameworks/libraries like React, Vue, Svelte, and so on.
  • A Solidity/Solana/Rust backend, built on top of the blockchain.

Learn what is a Decentralized Application:

Check DApp Radar to see real-world examples of Defi (Decentralized Finance) and other Blockchain-based applications

To understand how the front-end and the backend of a DApp work together: communicating and exchanging data, you need to learn Front-end development and the basic principles of standard backend development, APIs, and patterns.


4. Learn Front End Development in 2022

Javascript front-end books

As said Decentralized Applications have a standard vanilla JavaScript or JavaScript Framework Front-end, that’s why before delving into developing your first DApp, it’s key to learn the basics of Front-end development and how the web works.

Learn HTML, CSS, HTTP, JavaScript, pick a framework and start building static websites.

5. Should I Learn Backend Development to Become a Web3 Developer?

Yes and now.

Decentralized Applications backends vastly differ from “standard” applications backends, starting from the fact that Blockchain technology is used as the main source of decentralized data storage, whereas standard backends usually use Databases or Object Storages.

The majority of technical principles remain the same, though, and it’s not suggested to jump straight into blockchain and web3.0 development without a strong foundation of the main principle of standard web development

5.1 Learn Backend Development in 2022

Learning backend development it’s a very rewarding process: connecting DB, creating your own REST API and building the business logic that will power your tools, is a great step to take.

I’ve recently published The ultimate roadmap to backend development updated to 2022. You might want to give it a read!

Learn: Node, Express, DBs, HTTP, how to develop APIs, and start deploying cutting-edge applications.

2022 Roadmap to Backend Development with Free Resources.


6. Web3.0 and Solidity Development roadmap: learn What is Ethereum and How it Works

A web3.0 developer needs to understand how Ethereum works.

Illustration with ethereum Prisma logo in open hands

Ethereum is software running on a network of computers that ensures the replication and processing of small programs called Smart Contracts.

The majority of Decentralized applications, now run on top of the Ethereum Blockchain, Smart Contracts had also been implemented by the Ethereum Consortium, then “copied” by other Blockchains.

It’s key to become an Ethereum expert for a web3.0 and Solidity developer, at least in 2022.

Learn more about Ethereum in this video with Vitalik Buterin, one of the inventors of the Ethereum Blockchain talks about this technology.

If you want to explore further what Ethereum is, I heavily suggest you go and check the documentation and original Ethereum website.


7. Software on the Blockchain: Smart Contracts

Ethereum and Smart Contracts are like Bread and butter, you need to understand both.

A Smart Contract is software stored on a blockchain-based platform, that automatically executes an agreement.

It is written in Solidity, Rust, or Vyper (Solidity but in Python flavor), and it’s the key component of any Decentralized Application, powering its business logic and allowing you to store information on the blockchain, just like you would do in a standard Database.

8. Learn Solidity to Develop and Deploy Smart Contracts

Of course knowing what Smart Contracts are is not enough, as a Web3.0 or Blockchain Developer, you have to know how to write your own Smart Contracts and use them to power your own Decentralized Applications. Here is when Solidity comes in help.

Solidity is a high-level, contract-oriented programming language to write smart contracts, allowing programmers to write self-executing code that powers blockchain DApps.

Unfortunately, as we were saying, the web lacks good resources to learn about Solidity and Blockchain Development.

Here are the best 2022 Solidity free courses / platforms I’ve found:


9. A fully fledged Web3 Developer path

Web3.university collects the best tutorials about Web3 development, from zero to hero, from what is a Smart Contract, to how to create an Automated Market Maker.

13. Connect your DApp Front-end: Learn Web3.js or Ethers.js

Now that you know how to create Smart Contracts, you need a way to connect your front-end with your local or remote Solidity (or similar) backend, using anything from HTTP to Websockets.

To do so you can choose between two JavaScript Libraries:

  • Web3.js
  • Ethers.js

13.1 Learn Web3.js

19. Learn How to Test your Smart Contracts

Testing Your Blockchain Smart Contracts is Key.

Screen with javascript unit tests

What makes the Blockchain so special is the non-reversibility: once a Smart Contract is added, it can’t be edited or recalled, and its deployment also costs real money (GAS fees).

This is the reason why you should learn how to thoroughly test your smart contracts before deploying them.

How do I Test my Decentralized Application?

There are 4 types of testing to test your Smart Contracts:

  • Node Testing.
  • Functional Testing.
  • Performance Testing.
  • API Testing.
