Web3 Developer Roadmap
Web3 development domain is constantly evolving and currently, there are great opportunities for Web3 developers. In this section, we will discuss the roadmap for becoming a Web3 developer.
1. Knowledge of programming language
Computer coding is essential in the development of decentralized applications. Most of the blockchains require knowledge of programming languages for development. It is important to attain proficiency in programming languages like:
Solidity is one of the majorly used programming languages for blockchain projects.
2. Understand Blockchain concepts
The first and foremost thing that you need to start learning is Blockchain technology. A blockchain is a distributed database that is shared among a computer network’s nodes. It is best known for its role in cryptocurrency for maintaining secure records of transactions. So start by learning:
- Introduction to Blockchain Technology
- History of Blockchain
- Features of Blockchain
- Blockchain Structure
- Blockchain Transaction Life-cycle
- Components of Blockchain
- Blockchain Protocols and their Working
- Top Applications of Blockchain in the Real World
3. Ethereum
Ethereum is a decentralized blockchain that has smart contracts functionality. Smart contracts help users in transactions without the need for centralized systems. Records are safely distributed over the network and are unchangeable. The important concepts that you need to have a solid understanding of are:
- What is Ethereum?
- Components of the Ethereum Network
- What is an Ethereum Virtual Machine?
- Nodes and Clients in Ethereum
- How to Deploy a Smart Contract on Ethereum?
- What is Ethereum API?
4. Knowledge of Smart contacts
Smart contacts are automated programs that work on the blockchain network and make agreements easier. Smart contacts can be used for trading, enforcing legal agreements, and managing financial transactions. These are essentially code that runs when some criteria are satisfied and recorded in the blockchain. Smart contracts help you automate a process by starting the next operation when a particular circumstance is satisfied. So it is important to understand smart contracts, and their lifecycle and write smart contracts using solidity. You can refer to the topics mentioned below:
- What is a Smart Contract?
- How to Simply Deploy a Smart Contract on Ethereum?
- What is a Cryptographic Token?
- Non-Fungible Tokens
5. Learn Web3 frameworks
Knowledge of Web3 development frameworks is crucial for building decentralized applications. Web 3.0 makes it easy for developers to create and run applications. Some of the common Web3 development frameworks that you can start learning are:
- Truffle framework: Truffle is a unified framework for web development. It has tools that you need to develop smart contracts, manage, debug, and deploy easily. This framework helps the developer throughout the project lifecycle. For more details refer to creating dApps using the Truffle Framework.
- Hardhat framework: The main aim of this framework is to provide all the resources and tools to third-party developers. It supports Django and Ruby on Rails web development frameworks.
- Open Zeppelin SDK: This framework was launched in February 2018. It provides security tools and infrastructure for smooth development.
- Brownie Framework: It is a blockchain framework that helps to develop Nash equilibrium. It further allows automatic interactions of participants related to NFT marketplaces.

6. Understand cryptography
Another important concept that you need to master is cryptography. It is a practice of techniques for safe and secure communication in the presence of adversarial behavior. A Web3 developer needs to understand cryptography, its algorithms, and how these algorithms are developed.
Some of the important concepts that you need to refer to are:
- Cryptography and its Types
- Cryptography in Blockchain
- Blockchain Hash Function
- Block hashing
- Encrypt and decrypt Files With Password Using OpenSSL
7. Decentralized app development
So now you have a clear understanding of the basics it’s time to build your first decentralized application. By building this you will get hands-on experience and learn about the best practices of dApp development. You can start with Flutter and Blockchain – Hello World Dapp.
8. Stay updated
