It's 2025, a year full of potential for growth, innovation, and new opportunities and if you have been contemplating diving into the Web3 ecosystem as a developer, now is the perfect time to begin your journey.

This article’s aim is to a structured roadmap to guide you towards becoming a skilled Web3 developer capable of building the web3 applications of the future.

What is Web3

But first, let's talk about what Web3 is really about. Web3 is the third generation of the World Wide Web (WWW), also referred to as Web 3.0. It is a proposed future version of the internet that is built on blockchain technology.

Unlike the centralized model of Web2, which we all know as the regular internet we use in our day-to-day lives, it's aim is to move towards a more decentralized experience where users have better control over their data and digital assets which are brought to life through technologies like smart contracts, decentralized applications (dApps), and cryptocurrencies.

These technologies are different from traditional transactional methods because you can make safe transactions directly with others without involving third parties like banks or financial institutions.

What is Blockchain?

At the centre of web3 lies blockchain, which is a decentralized, secure, and transparent digital ledger that records transactions across a network of computers. It uses cryptography to link blocks of data together in a chain, making it difficult to alter or tamper with the stored information.

What is Blockchain Development

Blockchain development simply involves developing the infrastructure for creating and managing blockchain-based applications and services, such as digital currencies, smart contracts, and distributed applications. It also involves developing the tools and technologies needed to support the platform.

What is a Web3 developer?

Building on blockchain development, a web3 developer is a software developer who specializes in building decentralized applications (dApps) using blockchain technology. They use various tools and programming languages, to build and deploy smart contracts which are self-executing contracts with the terms of the agreement written directly into code.

They work on creating decentralized applications (dApps) that operate on blockchain technology and these applications are designed to be more secure, transparent and resistant censorship that traditional applications. They also work on decentralized finance (DeFi) applications, non-fungible tokens (NFTs) marketplaces, supply chain management solutions, identity verification platforms and new blockchain platforms and protocols.

With that being said, the Web3 space is exploding, and for a developer, this is both a unique and exciting opportunity but why exactly should you transition to web3?

What is the difference between Web2 and Web3

Putting it simply, web2 is the current state of the internet we interact with daily our social media apps, e-commerce or banking apps we use, while web3 represents the next-generation internet, a decentralized and futuristic version currently being developed with blockchain technology.

While web2 has experienced tremendous growth over the past 20 years, it comes with a significant trade-off: the internet is largely governed by centralized authorities that collect, control, and monetize our personal data. This centralized model has raised concerns about privacy, ownership, and the fairness of value distribution.

If you've ever wondered whether there's a way for power to be more evenly distributed and for users to have greater control over their digital lives, that's exactly where Web3 comes in.

Let’s look into the fundamental differences between these two generations of the web and how Web3 aims to reshape the internet as we know it:

Web2	Web3
Controlled by large, centralized companies	Controlled and governed by communities, including you and I
Limited control over your data	Ownership and better control over your data
It relies on third parties for transactions and interactions	Doesn't need intermediaries for your transactions
Vulnerable to censorship and content control	Resistant to censorship due to decentralization

Why become a Web3 developer

Firstly, Web3 is the future of the internet; decentralized, user-centric, and secure. You as a Web3 developer, will be working on some technologies like blockchain and cryptography to build innovative applications that could potentially revolutionize industries such as finance, healthcare, supply chain, and gaming. You will be at the forefront in this technological revolution, creating more secure and transparent systems that give power to users. Sounds exciting right? Ofcourse it does!

Web3 is also a relatively young field with fewer established developers and a smaller pool of experienced professionals and following its continous growth, there is more demand for skilled workforce to develop and maintain new and growing applications. There is also shortage of skilled talent which underlaps this demand leading to a less saturated ecosystem filled with opportunities, making it relatively easier to get connected with multiple opportunities compared to web2 which is highly saturated.

The web3 ecosystem is constantly evolving, requiring continuous learning and adaptation so there are more opportunity to grow and learn new and fresh concepts which can be exciting. So if you're passionate for technology and the blockchain then web3 development would be an excellent career choice for you.

What skills are required to become a Web3 developer

To become a successful web3 developer, a set of required skills is necessary for building decentralized applications based on blockchain technology. It includes but is not limited to the following:
