Roadmap for Web3 developers

Web by blockchain and a dream of decentralization? This is the Web3 project that some technophiles keep talking about at the end of 2022. But the logic of financialization that underlies this new fashionable concept is debated.

At the end of the year, Web3 joined the list of technological controversies, alongside the metaverse and the uses of artificial intelligence

For some, it’s an upcoming revolution that will transform the Internet as we know it. For others, a technophile delirium. But behind this nebulous expression, what do we mean by Web3?

This tutorial covers the details of how to start a career in building a blockchain as Web3 developer from scratch. The tutorial is suitable for institutes and training groups as well as for job seekers and training in the field.

We will also cover the most important skills needed as a developer for blockchain and cryptocurrencies. One of the most important things for developers is Bootcamp, both coding and non-coding. You can participate in them to learn and practice the required skills.

Verification of the facts: 

It’s time to become a Web3 developer as it offers an excellent salary and cutting-edge technology for the job. Several startups drive the blockchain adoption fee. Blockchain wallet users grew from 3 million in 2015 to 28 million in 2018.

Blockchain-related jobs have increased by 200 per cent since 2021. It is the number one job sought, and there are approximately crypto and blockchain posts increased by 34.8% the previous year in the United States alone. 

It was ranked in the top 20% of the fastest-growing companies with professional skills while the number of job postings increased by more than 200% for workers with these skills.

Where does the notion of Web3 come from?

If the expression resonates strongly today, the concept actually dates from 2014. The Web3 was thought up by Briton Gavin Wood, the co-founder of the famous cryptocurrency Ethereum, with Vitalik Buterin. 

The idea of ​​Web3 actually germinated more or less at the same time as the establishment of Ethereum: its conception dates back to 2013 and it was in 2015 that the platform was launched.

Web3 now benefits from the support of an ad hoc foundation, founded and led by Gavin Wood, which is aptly called the Web3 Foundation

On its homepage, it is announced that it is there to “ fund the research and development teams that are building the foundations of the decentralized web ”. Two associated projects are mentioned: Polkadot and Kusama.

For several years, the Web3 project remained well below the radar, but in 2022 it has aroused renewed interest from the media, Internet users, but also investors and companies. 

Why talk about it now? Because the technologies and notions mobilized by Web3 are starting to be rather widespread, thanks to the fashion for cryptocurrencies.

What are Web3 and its philosophy?

The project behind Web3 is to decentralize the net, using so-called blockchain technology (or chain of blocks), a mechanism that is the basis of cryptocurrencies such as Ethereum, Bitcoin and all the others.

It is the equivalent of a digital and public ledger in which all cryptocurrency transactions are recorded and stored.

In a Web3 environment, what is built on it would not belong to anyone. “ The platforms and applications will not be owned by a central player, but by the users, who will gain their share of ownership by contributing to the development and maintenance of these services ”, details Wired, during an exchange with Gavin Wood in November 2021.

In short, Web3 would therefore be a third generation of the net, where we would witness a transition from the current model, with online services and platforms, to an approach mobilizing common cryptocurrency technologies: cryptographic tokens and the blockchain. 

By possessing these tokens, one then has a certain amount of power — of decision.

The ideology behind Web3 is to attack the current web, which is characterized by economic concentration in the hands of a handful of net giants – which we summarize in broad strokes by the acronym GAFAM ( Google, Amazon, Facebook, Apple, Microsoft, and sometimes a few others) – which public authorities have trouble regulating.

This growing monopoly has also given rise to a rather striking formulation to illustrate the monopoly of a few key players: the ” TriNet “, where Internet users would spend most of their time surfing between Google, Amazon and Facebook, to the detriment of the rest from the net. 

In short, Web3 would like to blast all that and find a (re)-fragmented net.
