If you have been paying attention to tech news, you may have heard the term “Web 3.0”. But what exactly is it?
Let’s start with the basics. The internet as we know it today – with its websites, social media platforms and search engines – is often referred to as Web 2.0.
But Web 3.0 is thought to be the next generation of the internet. The technology for this is still developing, but its supporters believe it will be more intelligent, connected and decentralised than Web 2.0.
One key concept behind Web 3.0 is the semantic web. This refers to the idea that content on the internet should be structured and labelled in a way that allows machines to more easily understand it.
For example, if you search for “apple” on Google, you might get results for the fruit, the technology company or the record label. In a semantic web, the search engine would be able to determine the meaning and context of your query. So it would be able to deduce which “apple” you are looking for and provide more accurate results.
But the technology supporting Web 3.0 goes beyond just semantics.
For example, machine learning – a form of artificial intelligence (AI) that uses data and algorithms to copy how humans “learn” and gradually improve – is important for making the internet smarter and more personalised.

Another important technology is blockchain, an advanced way of storing data securely. It can enable applications and transactions that are decentralised, meaning no single group or person controls it and there is no need for intermediaries. If more of our data can be stored on the blockchain, the semantic web can access it to provide optimised search results and other services.
So what will Web 3.0 actually look like? One example would be personalised search engines. After you type in your search request, a Web 3.0-powered search engine could analyse your search history, social media and other data to provide the most useful results. Another example of Web 3.0 in action is a decentralised marketplace, where you could buy and sell goods and services without relying on a central authority like Carousell or HKTV Mall.
One technology that will depend heavily on the development of Web 3.0 is the metaverse – a term for a virtual world where people can interact with each other and with digital objects. Think of it like a massive, multiplayer online game. Some people believe the metaverse will be powered by Web 3.0 and that it can provide a new way for people to socialise, work and play.

Web 3.0 is still a work in progress, but it has the potential to revolutionise the internet. Whether you’re excited about the metaverse, sceptical of the new technology, or somewhere in between, it’s worth keeping an eye on Web 3.0 as it continues to develop.
For those who are interested in coding, artificial intelligence or just want to learn more about how the latest technology is shaping our world, there are endless opportunities to engage with the Web 3.0 community.
