Technology review – Web 3.0

The product of the same visionaries who have helped drive cryptocurrencies and blockchain technology, Web 3.0 is considered to be an evolution of user interaction with web technologies.

From Web 1.0’s “read-only web” (simply walls and walls of text information) to Web 2.0’s “read-write web” (allowing user interaction with dynamic websites),” Web 3.0, sometimes called the “semantic web,” will be a complete reinvention of the web.

Web 3.0 is most likely compared to an artificial intelligence assistant, by being able to get context from the user, and then in turn provide the very same user with most valuable information about a certain information. In other words, it simply understands its user and personalizes everything.

What greatly defines this 3rd generation web is that it has the concept of a distributed ledger (just like Bitcoin), providing more privacy and security and against the control of big organizations.

As what Gian Gonzaga, Ph.D., senior director of research and development at the dating site eHarmony, says, “The Web can give something back that was not previously known. Web 3.0 learns and understands who you are and gives you something back.”

Tl; dr;

Web 3.0 combines the best aspects of Web 1.0 and Web 2.0, allowing online applications and websites to receive information that’s on the Web and give new information/data to the users.

The term Web 3.0 was coined by the reporter John Markoff of The New York Times in 2006, referring to a new evolution of the web, its third generation, with specific innovations and practices.

Decentralized blockchain platforms including Ethereum, EOS, and NEO will make Web 3.0 more useful and dynamic than its predecessor, the Web 2.0.

An extension of Web 2.0, Web 3.0 creates a more personalized web experience with intelligent search and behavioural advertisements where content is generated by machines instead of by humans.

For instance, based on your opinion about a movie you’ve just watched or a restaurant you visited recently, you get a list of those whose interests coincide with yours as close as possible. Web 3.0 specifically target individuals based on their web history and user data using machines and algorithms.

Web 3.0 has 4 main properties:

Semantic Web.

The incoming generation of the Web involves the Semantic Web. It improves web technologies to generate, share and connect content through search and analysis, helping to evolve artificial intelligence that can utilize that information.

The term “Semantic Web” was first coined by Tim Berners-Lee, describing a web of data that can be processed by machines:

“I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A “Semantic Web”, which makes this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy, and our daily lives will be handled by machines talking to machines. The “intelligent agents” people have touted for ages will finally materialize.”

Artificial Intelligence.

Web 3.0 allows computers to understand information like humans to provide faster and more relevant results. Thus, they are becoming more intelligent to satisfy the needs of users, allowing websites to filter and present users the best data possible.

According to the University of Maastricht, “Machine learning algorithms are widely employed and are encountered daily. Examples are automatic recommendations when buying a product or voice recognition software that adapts to your voice.”

Websites such as Rotten Tomatoes lets its users vote on a list of movies. With that, movies with higher ratings are generally considered as good movies, allowing visitors to see upfront good data rather than going through bad data.

3D Graphics.

The next wave evolution of the Web will extensively use three dimensional design in websites and services such as e-commerce, real estate, online games, museum guides, etc. allowing for a more realistic cyber world.


Web 3.0 will be ubiquitous (the idea of being everywhere at the same time i.e. omnipresent), meaning content is accessible by multiple applications, every device is connected to the web, and the services can be used everywhere. This web generation will may as well be called as the web of everything and everywhere as most of the things around us are connected online.

The Pros and Cons of Web 3.0

Even though the incoming generation of the web will give better convenience with our day to day, let us also put into consideration the downsides as well.


  • More specific information data
  • More valuable search results
  • With the Internet being more personalized, accomplishing tasks will be much easier
  • Easier knowledge sharing
  • Scamming incidence due to fake identity will be much lesser because Web 3.0 is more secure (blockchain technology).


  • Privacy policy should be addressed than ever
  • Reputation management will be much needed than ever
  • Your user search results and user data will be used by companies for marketing
  • Personal/private information will be easier to find
  • With exciting features and better convenience, people will now spend more time on the Internet than ever
  • Less anonymity
  • People that aren’t active on the Web 3.0 “don’t exist”


In Web 3.0, data will come from the user and the web will then essentially adjust to meet the needs of the user. The new generation of the Web will be more connected, more open, and more intelligent, having to be equipped with distributed databases, semantic web technologies, natural language processing, machine learning and reasoning, and autonomous agents.
