Building on the current web 2.0, the next incarnation of the internet is referred to as web 3.0 or Web3. Read on to discover how the third generation of the world wide web aims to provide a more intelligent and connected user experience.

At this point in time we are in transition between Web 2.0 and 3.0. The primary mission of web3 is to empower users, instead of the control residing mainly with corporations and companies. It’s this shift in focus that makes Web3 so important.

What’s the difference between web 1.0, web 2.0, web 3.0?

The standout difference between web 3.0 and its predecessors is the fact it is a decentralised model, with data being stored and shared across many devices, as opposed to being only on centralised servers. Having data shared securely across many locations provides a safeguard and reduces risks of large-scale data breach.

 Let’s take a quick peek at previous manifestations of the web.

 Web 1.0

The first step into the world wide web, version 1.0 was a static, read-only experience for users. Driven by web browsers and HTML, HTTP and URL technology, elements were hyperlinked together and there were no search engines to speak of. This passive experience saw reading information as the only interaction between user and platform.

 Web 2.0

Moving on up, 2.0 provides a two-way experience where users can interact by reading and creating content on sites and apps and sharing it between platforms. 2.0 is highly centralised with the big players having a monopoly on the associated user data (think YouTube, Meta/Facebook, Twitter) which they monetise. This extreme imbalance of data ownership and therefore power, along with increased widespread privacy and security concerns, is creating the need for the next generation of the internet.

Key features of web 3.0

Beyond the decentralisation of data, other differences between 3.0 and previous versions are not as clearly defined. There are, however, some key features of 3.0 that provide more definition. 

  • Semantic web

The semantic web is where online pages are structured and tagged in a way that supports computers to directly read and process them at scale and better understand all digital content.

 The benefit of this development is that massive quantities of data and knowledge is easily accessed and read by machines (this includes AI bots and virtual assistants), which results in algorithms needing less data to produce relevant results for users. The machines can analyse the context of the data, not just the data on its own.

  • Artificial intelligence (AI)

A fundamental aspect of Web3, AI is tasked with improving the user experience by providing better content recommendations and human-machine interaction. AI will offer sophisticated learning algorithms and analytics to help machines learn and better process, or understand, digital content.

 AI-powered recommendation already exists with web 2.0 offerings, such as content streaming services that analyse viewer activity. These algorithms will be central to Web3, as they can analyse massive quantities of user data and create predictive models for the individual. As a result, the user will get a more tailored and personalised experience.

  • Blockchain

Already existing within cryptocurrency ecosystems, blockchain technology enables peer-to-peer payments and the collection of digital assets. So, what is blockchains’ role in web 3.0? In the new wave, blockchain networks replace centralised databases. 

With blockchain, you’ll only need a single username and password to access everything that has become decentralised, not one for each platform or service. Blockchain technology will support and facilitate the overall decentralisation that Web3 promises to bring.

  •  Connectivity

All data will be more connected because of semantic metadata. This will result in a better user experience overall as the higher rate of connectivity of information online will provide stronger search results.

What’s an example of a web3 app that exists today?

what is web 3 examplesThe following are three examples of Web3 applications you may already be familiar with.

  •  Blockchain technology

Predominantly used with cryptocurrency and non fungible tokens (NFTs), blockchain technology is a prime example of Web3 application.

  •  Cryptocurrency

Essentially decentralised digital cash that is controlled by users, as opposed to centralised authorities such as a bank, cryptocurrency is a strong example of a web3 app.

  •  Non-fungible tokens (NFTs)

Fundamentally another form of crypto, NFTs are unique and not exchangeable for another. They’re linked to digital or physical assets such as artworks, or paper deed titles and represent the ownership of the item.

How to learn web 3.0

The development of web3 brings with it a range of exciting employment opportunities. Completing industry-approved training in Software Engineering or Web Development is a sure-fire way to learn how to develop and maintain systems, from small applications to large-scale online platforms. This training will give you the foundational skills needed to launch a career involved in the next evolution of the internet.

With massive industry demand and a shortage of IT talent, training in tech will see you future-proofing your career.
