Learning Web3 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.
After the incredible success of the Complete Solana Development Roadmap I’ve taken the time to gather the best online videos, courses, and websites and put together the best web3 and Solidity developer 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
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).

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 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
The Complete 2022 Front-end development Roadmap with 15+ Free resources to kickstart your journey and start monetizing your skills.
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 Storage.
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 with Free Resources. You might want to give it a read!
Learn: Node, Express, DBs, HTTP, how to develop APIs, and start deploying cutting-edge applications.
6. Web3 and Solidity Developer Roadmap: learn What is Ethereum and How it Works
A web3.0 developer needs to understand how Ethereum works.
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.
Learn what Smart Contracts are, in this free Course Course by the University of Virginia.
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:
- Alchemy University
- Nader Dabit – Full-stack web3 development tutorials
- Solidity in 32hrs + Blockchain – freecodecamp
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.

11. Learn Solidity by Creating Zombies
Turns out one of the best resources to learn about Solidity is a Gamified Programming course, where you’ll learn how to develop Smart Contracts while creating a Zombie factory to start your world domination plan.
The game is divided into sections, going from complete newbie to advanced Solidity developer. I suggest you to play it while following one of the other suggested courses, as it helps with practice.
Check out CryptoZombies, is completely Free.
12. 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.
12.1 Learn Web3.js
Here’s the full web3.js crash course by DApp University.
12.2 Learn Ethers.js

Other DApps Project Inspirations
Finding project ideas to showcase in your blockchain developer portfolio, might not be that intuitive.
Let me share with you 6 projects ideas to practice your web3.0 knowledge.
16. Learn HardHat
Sometimes REMIX IDE won’t be enough, and bringing your project to the good old VSCode will be the only decision to take.
To do this, you’ll need to set up a local Ethereum Development environment, and that is exactly what HardHat helps with.
HardHat comes with a set of fundamental functionalities to create, test, and deploy your decentralized applications on multiple chains, like Polygon, Ropsten, Ethereum Mainnet, and many more.
It will also give you the ability to spin up a local ethereum node to test your Smart Contracts without the need of deploying them on a public Blockchain.
Learn about HardHat in this Full Stack Ethereum Development tutorial by Nader Dabit.
17. Learn Truffle And Ganache
Speed Up Your Development With Truffle: a development environment, testing framework, and asset pipeline for any EVM Blockchain.
It comes with:
- Built-in smart contract compilation
- Scriptable migration framework
- and more.
Ganache on the other side comes included in the Truffle suite and is used to Test Ethereum Contacts. It essentially creates a simulated blockchain with accounts to test your transactions and avoid setting up useless boilerplates to kickstart your DApp development.
Start exploring Truffle in this Tutorial for beginners.
Learn Ganache from the official Documentation.
18. Learn How to Test your Smart Contracts
Testing Your Blockchain Smart Contracts is Key.
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.
Learn More about testing your Decentralized Applications and Smart Contracts, in this 1hr free introduction to Blockchain Tests.
Learning Web3.0 and blockchain development might sound daunting at first, but everyone can do it.
You won’t learn Blockchain Development in 1 week, but you can do it in 1 year of full commitment.
This is awesome

It’s such a wonderful article. I am a complete newbie to programming. I know if I start I will be somewhere in no time. Thank you Vitto. I will follow you on everything.
Thank you for your words Daniel! Means a lot
Hello Vittorio, thank you for the educational content. How long do you think it will take a newbie in programming to learn all this if they give 5 hours a day to learning? Your respond will be really helpful.Thanks
Hey Israel! giving 5hrs per day, every day – weekends will take you 6 months to 1 years to be up and running and join a junior developer position 🙂
It really depends though, it might take you 2 months, or two years depending on a bunch of different factors.
Can I follow the same roadmap now in 2022
Thank you for making me move out of DBA to solidity developer. You laid the foundation steps for me. Kudos to the effort.
Thankyouu for this roadmap Sir .. Right now am learning JS ..and you gave me the end goal of 2022 🙂
Thanx for detaled and ineteresting explanation! What amuses me most – why there are so many sceptics around web 3.0? As for me, it’s the greatest way out for those who looks for a total privacy online. If you can’t get the idea – check the working principles of Utopia p2p. It’s a great representative of web 3.0 with a several years of experience.
Help me a lot Ethernaut, from OppenZeppelin. It’s a war game to improve solidity.
Hey Vitto ,
This is like a life changing adventure for anyone .
My doubt is
How much coding intensive a job is of web3 or blockchain developer ?
Because I can understand the basics of coding but don’t coding intensity requires in this or not ?
my doubt – does it require to be the hardcore coding expert or just the understanding or doing just doing the said courses is just enough ?
People will easily get lost seeing the bulk of resources you shared. You shall only outline those resources which are currently used in industry and shall only give 1 path than many.
Thanks so much! You hit the nail on the head saying it’s tough to find a proper roadmap!
Thanks for this Epic Roadmap Vittorio Rivabella!
Also if there are any Paid Courses that are worth doing or paying for, please do share those as well.
As much as possible I want to treat this as an Investment in myself.
Time Investment is a given, but definitely willing to Pay Premium if need be.
But the fact that we can Learn most of what we need to learn is “Free”, is already amazing, so thanks again for taking the time to reference mostly Free Accessible content in our Journey to become Web 3.0 Devs.
I’ll Reply my Web 3.0 Journey as much as Possible.
awesome roadmap it fulfills what it says zero to hero
Thanks for the RoadMap ~ This article is a kind of DApp which be filled with the spirit of sharing. Thanks a lot ~! 🙂
