Complete Web3.0 And Solidity Development Roadmap 2022

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

 

1. Blockchain fundamentals

As a Web3 developer, you need to understand the technology at the core of this trend, blockchain. 

  • Blockchain Theory 101 – This course will teach you the basics and potential applications of blockchain technology.
  • Blockchain: Foundations and Use Cases – Ideal for both non-developers and developers who want to thoroughly learn about the fundamentals of Blockchain. This course isn’t limited to the technology side of blockchain; it will also introduce the philosophical concepts of decentralization.
  • Blockchain Fundamentals by UC Berkeley – This course will give you a deep understanding of and let you build your own blockchain.Difference between distributed ledger technology and blockchain | by Naveen  Saraswat | Sodio Technologies | Medium

2. What is Decentralize App?

Dapp stands for Decentralized Application and refers to the applications built on top of blockchains. Dapps are generally composed of two parts:

  • A standard Front-end built using traditional tooling, such as HTML and JavaScript (including frameworks/libraries like React, Vue, Svelte, and so on).
  • A Solidity/Solana/Rust backend, is the part that distinguishes the application as a Dapp. This backend is what interacts with the blockchain you are building on.


Many popular ecosystems such as Ethereum, Gemini, and Solana, all have tutorials and introductions to Dapps:

3. Getting started with Front-end-development

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.

4. Should I learn backend development?

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.

Understand how front-end and backend exchange data.
Learn: Node, Express, DBs, HTTP, how to develop APIs, and start deploying cutting-edge applications.

5. 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.

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 hardly suggest you go and check the documentation and original Ethereum website.

7. How do smart contracts work?

Smart contracts are self-executing programs that run on a blockchain when predetermined criteria are met. They’re generally used to automate the performance of a deal so that everyone can know the result right away, without any third-party involvement or time loss. 

Financial applications like trading, investing, lending, and borrowing are just a few of the uses for smart contracts. They may be utilized in gaming, healthcare, and real estate, and they can even be used to build whole company structures.

8. What is solidity

Solidity Logo

Solidity is a compiled object-oriented programming language created by the Ethereum team that has similar syntax to Javascript. Unlike Javascript, however, Solidity uses inheritance and is strongly typed. 
The main purpose of the language is to develop and deploy contracts onto a blockchain, and is becoming one of the most valuable and in demand languages to learn right now. 

9. Learn solidity by building projects

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.

Check out CryptoZombies, is completely Free.

9. 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

10. Learn Web3.js

web3.js is a collection of libraries that allow you to connect with a local or remote Ethereum node using HTTPWebsockets, and other communication protocols directly from your JavaScript Based front-end.

Here’s the full web3.js crash course by DApp University.

11. Learn Ethers.js

Ethers.js is a lightweight JavaScript library used as an alternative to Web3.js to connect JavaScript front-end with Smart Contacts.

12. Learn Truffle And Ganache Truffle Logo

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.

Conclusion

Learning Web3.0 and blockchain development might sound daunting at first, but everyone can do it.

Learn step-by-step using starting from the fundamentals of Computer Science, to JavaScript, from solidity to cutting edge DeFi applications.

You won’t learn Blockchain Development in 1 week, but you can do it in 1 year of full commitment.
